Abstract
Description
Technical Field
[0001] The present application relates to the technical field of massage chairs, and in particular to a massage chair calf anti-pinch mechanism and a massage chair. Background Art
[0002] With the development of society, people gradually began to pursue a high standard of life, and massage chairs came into being. In order to improve comfort, the massage chair will change its posture, so that the calf changes between expansion and reduction. During reduction, due to internal structural limitations, the distance between the calf and the internal structural parts often becomes very small. If small animals or human body parts enter this narrow space at this time, it is easy to cause safety hazards.
[0003] The existing anti-pinch systems for calf can be roughly divided into: 1. Electronic anti-pinch system; 2. Mechanical anti-pinch system. The electronic anti-pinch system is subject to the reliability of electronic products. Once the anti-pinch electronic components are damaged, there will still be safety hazards. The mechanical anti-pinch system can ensure the stability of the anti-pinch system. However, most of the existing mechanical anti-pinch systems have defects such as small anti-pinch distance and large space occupation, and their applicability is poor. Utility Model Content
[0004] In order to solve the shortcomings of the existing mechanical anti-pinch system, such as small anti-pinch distance and large occupied space, the present application provides a massage chair calf anti-pinch mechanism, which is arranged between the seat frame and the calf frame of the massage chair, and the calf frame is hinged to the seat frame.
[0005] It includes a driving member, a fixed seat and a sliding member; the fixed seat is connected to the seat frame, one end of the sliding member is hinged to the driving member, and the other end of the sliding member slides back and forth in the fixed seat; one end of the driving member away from the sliding member is hinged to the calf frame, and the driving member drives the calf frame to rotate around the seat frame;
[0006] When the driving member drives the calf frame to be retracted toward the seat frame, the driving member pulls the sliding member to slide in the fixing seat.
[0007] In one embodiment, it also includes an elastic telescopic member, which is arranged between the sliding member and the seat frame or the fixed seat; during the sliding process of the sliding member, the elastic telescopic member is deformed to generate a pulling force on the sliding member, thereby limiting the sliding of the sliding member.
[0008] In one embodiment, a limiting member is further included, the limiting member is fixed on the fixing seat, a sliding groove is provided in the middle of the sliding member, and the limiting member slides back and forth in the sliding groove.
[0009] In one embodiment, a massage structure and a support structure are provided on the calf rack. The support structure is used to support the user's calf, and the massage structure is used to massage the user's calf. The user can apply pressure to the calf rack through the support structure to rotate the calf rack relative to the seat frame.
[0010] In one embodiment, one end of the elastic telescopic member is hinged to the sliding member through a first hinge shaft, and the other end of the elastic telescopic member is connected to a seat frame or a fixed seat; the first hinge shaft is fixed to one end of the sliding member close to the driving member.
[0011] In one embodiment, two sliding members are provided.
[0012] In one embodiment, the elastic telescopic member is a tension spring, and the driving member is an electric push rod.
[0013] In one embodiment, a supporting protrusion is provided at one end of the sliding member away from the driving member.
[0014] In one embodiment, one end of the elastic telescopic member away from the first hinge shaft is hinged to the fixing seat through the second hinge shaft.
[0015] The present application also provides a massage chair that adopts any of the massage chair calf anti-pinch mechanisms described above.
[0016] Based on the above, compared with the prior art, the massage chair calf anti-pinch mechanism provided in the present application provides the driving part with an anti-pinch margin through a sliding part. When the driving part is blocked from retracting the calf, the reaction force exerted on the driving part triggers the sliding of the sliding part, which can effectively avoid safety problems such as pinching injuries, and has a simple and reliable structure with a high degree of integration.

DETAILED DESCRIPTION
[0029] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments; the technical features designed in different implementation modes of the present application described below can be combined with each other as long as they do not conflict with each other; based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0030] In the description of this application, it should be noted that all terms (including technical terms and scientific terms) used in this application have the same meanings as those generally understood by ordinary technicians in the field to which this application belongs, and cannot be understood as limitations on this application; it should be further understood that the terms used in this application should be understood to have meanings consistent with the meanings of these terms in the context of this specification and in the relevant fields, and should not be understood in an idealized or overly formal sense, unless explicitly defined in this application.
[0031] like Figures 1 to 8 As shown, the present application provides a massage chair calf anti-pinch mechanism 100, which is arranged between a seat frame 200 and a calf frame 300 of the massage chair, and the calf frame 300 of the massage chair is hinged to the seat frame 200.
[0032] The massage chair calf anti-pinch mechanism 100 includes a driving member 110, a fixed seat 130 and a sliding member 120. The fixed seat 130 is connected to the seat frame 200, one end of the sliding member 120 is hinged to the driving member 110, and the other end of the sliding member 120 slides back and forth in the fixed seat 130. Specifically, the sliding member 120 and the fixed seat 130 can adopt the sliding form of a slide rail and a slide groove 121, and the tightness of the sliding and the pulling force to trigger the sliding can be adjusted according to actual needs by those skilled in the art.
[0033] One end of the driving member 110 away from the sliding member 120 is hinged to the calf frame 300 , and the driving member 110 pushes the calf frame 300 to rotate around the seat frame 200 .
[0034] When the driving member 110 drives the calf frame 300 to be retracted toward the seat frame 200 , the driving member 110 pulls the sliding member 120 to slide in the fixing seat 130 .
[0035] In actual work, Figures 6 to 8 As shown, due to the shape limitation of the massage chair itself, a blocking surface is usually set between the calf frame 300 and the seat frame 200 to protect the internal structure of the seat frame 200. Therefore, when the calf frame 300 is retracted, if an object enters the space between the calf frame 300 and the seat frame 200, it will be squeezed by the two surfaces of the seat frame 200 and the calf frame 300. During the retraction process, the driving member 110 generates a pulling force on the calf frame 300, pulling the calf frame 300 to rotate. When the retraction is blocked, the calf frame 300 continues to rotate. Driven by the reaction force, the driving member 110 pulls the sliding member 120 to slide, and the sliding member 120 slides out, so that the space between the calf frame 300 and the seat frame 200 will not excessively squeeze the obstructing object, and at the same time, it can also prevent the driving member 110 from being damaged due to excessive force.
[0036] Preferably, Figures 1 to 8 As shown, it also includes an elastic telescopic member 140, which is arranged between the sliding member 120 and the seat frame 200 or the fixed seat 130; during the sliding process of the sliding member 120, the elastic telescopic member 140 is deformed to generate a pulling force on the sliding member 120, thereby limiting the sliding of the sliding member 120. The setting of the elastic telescopic member 140 can not only accurately control the trigger force of the sliding member 120, but also automatically retract the sliding member 120 after the obstructing object leaves, thereby ensuring the normal operation of the calf retraction process. Specifically, the elastic telescopic member 140 can be an elastic member such as a spring or a rubber band.
[0037] Further, such as Figures 3 to 5As shown, the positioning member 150 is also included, and the positioning member 150 is fixed on the fixing seat 130. A slide groove 121 is provided in the middle of the sliding member 120, and the positioning member 150 reciprocates in the slide groove 121. The positioning member 150 can limit the sliding distance of the sliding member 120 and ensure that the sliding member 120 does not fall out of the fixing seat 130. Specifically, the positioning member 150 can be in the form of a positioning block or a limiting hinge shaft, and those skilled in the art can select according to actual conditions, and no specific limitation is made.
[0038] Furthermore, Figures 3 to 5 As shown, the slide groove 121 of the sliding member 120 passes through the sliding member 120, and the limiting member 150 passes through the slide groove 121 and is connected to the fixing seat 130. This arrangement can ensure the cooperation between the slide groove 121 and the limiting member 150 to avoid jamming or the limiting member 150 falling out of the slide groove 121.
[0039] Furthermore, a blocking structure is provided on the slide groove 121, and the blocking structure can change the sliding distance of the sliding member 120, so that the whole can adjust the sliding distance, that is, the anti-pinch distance. Specifically, a reserved screw hole can be provided on the sliding member 120, and the blocking structure is installed on the sliding member 120 through the reserved screw hole, and contacts with the limiter 150 during the sliding process to limit the sliding distance of the sliding member 120.
[0040] In one embodiment, a massage structure and a support structure are provided on the calf frame 300, the support structure is used to support the user's calf, and the massage structure is used to massage the user's calf. The user can apply pressure to the calf frame 300 through the support structure to make the calf frame 300 rotate relative to the seat frame 200. This arrangement can further simplify the components while meeting the anti-pinch requirements.
[0041] In one embodiment, if Figures 3 to 5 As shown, one end of the elastic telescopic member 140 is hinged to the sliding member 120 through the first hinge shaft 160, and the other end of the elastic telescopic member 140 is connected to the seat frame 200 or the fixed seat 130; the first hinge shaft 160 is fixed to one end of the sliding member 120 close to the driving member 110. The elastic telescopic member 140 is hinged to the sliding member 120 through the first hinge shaft 160, so that the elastic telescopic member 140 can adapt to the angle change of the sliding member 120 during the sliding process of the sliding member 120, ensuring that the tension of the elastic telescopic member 140 on the sliding member 120 is overall balanced and stable, avoiding excessive stretching of a single part, and improving the service life.
[0042] Preferably, Figures 1 to 8 As shown, there are two sliding members 120, and such an arrangement can ensure the overall stress guidance balance and improve the stability and life of the structure.
[0043] In one embodiment, if Figures 1 to 8As shown, the elastic telescopic member 140 is a tension spring, and the driving member 110 is an electric push rod.
[0044] In one embodiment, if Figure 5 As shown, a support protrusion 122 is provided at one end of the sliding member 120 away from the driving member 110. The support protrusion 122 can reduce the friction between other parts of the sliding member 120 and the fixing seat 130 during the sliding process of the sliding member 120, thereby ensuring smooth sliding.
[0045] In one embodiment, one end of the elastic member 140 away from the first hinge shaft 160 is hinged to the fixing seat 130 via the second hinge shaft 170 .
[0046] The present application also provides a massage chair that adopts any of the massage chair calf anti-pinch mechanisms 100 described above.
[0047] In addition, those skilled in the art should understand that, although there are many problems in the prior art, each embodiment or technical solution of the present application can be improved in only one or several aspects, without having to solve all the technical problems listed in the prior art or background technology at the same time. Those skilled in the art should understand that the content not mentioned in a claim should not be used as a limitation on the claim.
[0048] Although the terms such as massage chair calf anti-clamp mechanism, driving member, sliding member, slide groove, support protrusion, fixed seat, elastic telescopic member, limiter, first hinge shaft, second hinge shaft, seat frame, calf frame, etc. are used more frequently in this article, the possibility of using other terms is not excluded. The use of these terms is only to more conveniently describe and explain the essence of this application; interpreting them as any additional restrictions is contrary to the spirit of this application; the terms "first", "second", etc. (if any) in the description and claims of the embodiments of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
