Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.
[0045] As people's quality of life improves, they pay more attention to their bodies. Massage chairs use mechanical force to massage the human body to improve human discomfort.
[0046] Massage chairs usually include a pressing structure and a driving mechanism. The driving mechanism drives the pressing structure to achieve massage of the human body. In order to increase the massage effect, some massage chairs use dual movements, that is, two different movements are installed on a massage chair. The two movements drive different objects and provide differentiated massages for different parts of the human body. For example, the dual movement includes a movement for neck massage and a movement for back, waist and hip massage. The use of dual movements can achieve better massage effects than a single-movement massage chair.
[0047] However, at present, when the movement for neck massage and the movement for back, waist and hip massage are moving on their respective tracks and toward each other, the two are prone to collision, thereby affecting the normal operation of the movement.
[0048] Based on this, the present application discloses an anti-collision movement assembly for a massage chair. By arranging an anti-collision device on the movement, it is possible to avoid collision between the movement for neck massage and the movement for back, waist and hip massage when they move towards each other, thereby ensuring the safety of the movement and ensuring the normal operation of the movement.
[0049] like Figure 1 and Figure 2 As shown, the massage chair in the present application includes a leg support 1, a back frame assembly 2 and a connecting bracket 3, wherein the leg support 1 is connected to the back frame assembly 2, and the back frame assembly 2 and the leg support 1 can rotate relative to each other, and the relative rotation includes that the leg support 1 is fixed and the back frame assembly 2 rotates relative to the leg support 1; or the leg support 1 rotates relative to the back frame assembly 2 and the back frame assembly 2 is fixed. The connecting bracket 3 is the entire installation base, the back frame assembly 2 is installed above the connecting bracket 3, and the leg support 1 is connected to the side of the connecting bracket 3, and the back frame assembly 2 and the leg support 1 can form a space for a human body to lie on.
[0050] A leg massage structure can be provided at the leg support 1 to increase the massage effect of the massage chair. The structure of the leg support 1 and the leg massage structure are not specifically limited here, and reference can be made to the existing structure for leg massage. The connecting bracket 3 includes but is not limited to a connecting rod structure, and any structure that can achieve support is acceptable. Optionally, the leg support 1 can be rotatably mounted on the connecting bracket 3, and the back frame assembly 2 can be rotatably mounted on the connecting bracket 3. The back frame assembly 2 is used to support the waist, hips and back of the human body, so the shape of the back frame assembly 2 can be set according to ergonomics.
[0051] Combination Figures 1 to 4 The back frame assembly 2 is provided with an anti-collision movement assembly, and the anti-collision movement includes: a first movement assembly 4, a second movement assembly 5, an anti-collision block 6 and an anti-collision assembly 7.
[0052] The first movement assembly 4 and the second movement assembly 5 are both movably mounted on the back frame assembly 2 of the dual movement massage chair. The first movement assembly 4 is used to massage a first part of the human body, and the second movement assembly 5 is used to massage a second part of the human body. In some embodiments, the first part includes but is not limited to the head, shoulders and / or neck, and the second part includes but is not limited to the back, waist and / or buttocks. It can be understood that the first part and the second part are different parts of the human body.
[0053] The first movement assembly 4 and the second movement assembly 5 include a first movement and a second movement respectively, and the first movement can enable the first movement assembly 4 to move on the back frame assembly 2 , and the second movement can enable the second movement assembly 5 to move on the back frame assembly 2 .
[0054] During operation, the first movement assembly 4 and the second movement assembly 5 of the massage chair in the present application will reciprocate along the position between the head and waist of the human body. Therefore, one of the first movement assembly 4 and the second movement assembly 5 in the present application is provided with an anti-collision block 6, and the other is provided with an anti-collision assembly 7. The anti-collision assembly 7 has a sensing unit, and the anti-collision assembly 7 is abutted against the anti-collision block 6 to trigger the sensing element, which is used to control the start and stop and driving direction of the first movement and the second movement.
[0055] In the present application, an anti-collision block 6 is provided in one of the first movement assembly 4 and the second movement assembly 5, and an anti-collision assembly 7 with a sensing element is provided in the other. When the anti-collision block 6 and the anti-collision assembly 7 collide with each other, the sensing element is triggered, and the first movement and the second movement are controlled to stop working and drive in opposite directions, so that the first movement assembly 4 and the second movement assembly 5 move away from each other, thereby avoiding collision of the movement assemblies and ensuring the normal operation of the movement assemblies.
[0056] The specific structure of the first movement assembly 4 and the second movement assembly 5 in the present application can refer to the existing massage structure. For example, the first movement assembly 4 and the second movement assembly 5 respectively include a drive motor and a massage piece, and the massage piece includes but is not limited to a massage ball. The drive motor can drive the massage piece to move and / or rotate. During the operation of the first movement assembly 4 and the second movement assembly 5, the drive motor of the first movement assembly 4 drives the corresponding massage ball to move and / or rotate to achieve massage of the first part of the human body, and the drive motor of the second movement assembly 5 drives the corresponding massage ball to move and / or rotate to achieve massage of the second part of the human body. The movement of the massage piece includes moving in a direction perpendicular to the back frame assembly 2. The direction of movement of the first movement assembly 4 and the second movement assembly 5 along the head and waist of the human body is achieved by the first movement and the second movement.
[0057] In some embodiments, the back frame assembly 2 includes a frame, a guide rail 21 and a covering, wherein the frame is connected to the connecting bracket 3, the shape and size of the frame are not specifically limited, and one end of the frame is connected to the leg support 1. The guide rail 21 extends in the direction of one end of the frame close to the leg support 1 and the direction of one end away from the leg support 1. It can be understood that the guide rail 21 extends in the direction of the top and bottom of the back frame assembly 2 to achieve the reciprocating movement of the first movement assembly 4 and the second movement assembly 5 in the relative directions of the first part and the second part of the human body. The covering is the epidermis covering the outside of the frame and the guide rail 21, and the covering includes but is not limited to leather or cotton.
[0058] There are two guide rails 21 symmetrically arranged on both sides of the frame. The first movement assembly 4 and the second movement assembly 5 are both connected to the two guide rails 21 at the same time to improve the stability of the first movement assembly 4 and the second movement assembly 5 during operation.
[0059] Exemplarily, the anti-collision block 6 is installed on the side of the first movement assembly 4 facing the second movement assembly 5. The anti-collision block 6 may be a bar-shaped block fixed on the first movement assembly 4. The installation position of the anti-collision block 6 on the first movement assembly 4 may not be specifically limited. Optionally, the anti-collision block 6 is installed between the two guide rails 21. The anti-collision component 7 is installed on the second movement assembly 5 and arranged opposite to the anti-collision block 6. It should be noted that the relative arrangement is that the anti-collision component 7 is located on the side of the second movement assembly 5 close to the anti-collision block 6 and is arranged toward the anti-collision block 6. The anti-collision block 6 can be abutted against the anti-collision component 7, and can trigger the sensing element when abutting.
[0060] Combination Figures 5 to 7 As shown, the anti-collision assembly 7 in the present application includes: a rotating member 71 , a fixing seat 72 , a reset torsion spring 73 , a sensing element 74 , a limiting shaft 75 , a rotating shaft 76 and a fastener 77 .
[0061] Among them, the fixed seat 72 is fixed on the second movement assembly 5, the rotating member 71 is rotatably installed on the fixed seat 72 through the rotating shaft 76, and the reset torsion spring 73 is sleeved on the rotating shaft 76, and one end is against the rotating member 71, and the other end is against the fixed seat 72. During the rotation of the rotating member 71 relative to the fixed seat 72, the reset torsion spring 73 is deformed. After the external force is cancelled, the reset torsion spring 73 can realize the reset of the rotating member 71 relative to the fixed seat 72.
[0062] In some embodiments, the first end of the rotating member 71 is rotatably mounted on the fixed seat 72 via a rotating shaft 76. The rotating member 71 is a U-shaped member. The fixed seat 72 is located in the U-shaped space of the rotating member 71. The rotating shaft 76 is inserted into the through hole of the rotating member 71 and the through hole of the fixed seat 72, so that the rotating member 71 is sleeved on the outside of the fixed seat 72. The rotating shaft 76 is arranged along the two side walls of the U-shaped structure of the rotating member 71. During the rotation of the rotating member 71 around the rotating shaft 76, the U-shaped space of the rotating member 71 can be moved in the direction of approaching and away from the fixed seat 72.
[0063] The middle position of the rotating member 71 disclosed in the present application can be limited by the limiting shaft 75 against the fixed seat 72. The limiting shaft 75 is penetrated in the middle position of the rotating member 71, and the fixed seat 72 is provided with an arc surface 721. When the limiting shaft 75 of the rotating member 71 is inserted into the arc surface 721, the rotating member 71 is fixed relative to the fixed seat 72; when the rotating member 71 is squeezed by an external force, the second end of the rotating member 71 will move toward the direction close to the fixed seat 72, and during the rotation of the rotating member 71, the limiting shaft 75 will be separated from the arc surface 721. It can be understood that the arc surface 721 can be a positioning groove, including but not limited to an arc surface, as long as it can achieve the effect of being against the limiting shaft 75.
[0064] Of course, the limiting shaft 75 and the arc-shaped surface 721 may also be limiting components of other structures, as long as the relative fixation of the rotating member 71 with respect to the fixing seat 72 can be achieved.
[0065] The fixed seat 72 is fixed with a sensing element 74. When the rotating member 71 rotates toward the fixed seat 72, the rotating member 71 triggers the sensing element 74. It should be noted that when the limit shaft 75 is engaged with the arc surface 721, the rotating member 71 is in the initial position. Figure 6 When the second end of the rotating member 71 rotates toward the fixed seat 72 and squeezes the reset torsion spring 73, and the sensing element 74 is triggered, the rotating member 71 is in the trigger position, such as Figure 7 shown.
[0066] Exemplarily, the sensing element 74 is a pair of optocoupler sensing elements, specifically a receiving end and a transmitting end. A light-shielding rib 711 is provided in the middle position of the rotating member 71. When the second end of the rotating member 71 rotates toward the fixed seat 72, the light-shielding rib 711 of the rotating member 71 can be located in the middle of the receiving end and the transmitting end, and the optocoupler sensing element is triggered. When the second end of the rotating member 71 rotates away from the fixed seat 72, the light-shielding rib 711 is not located between the receiving end and the transmitting end, and the sensing element 74 is not triggered.
[0067] Based on the above principle, when the anti-collision block 6 and the anti-collision component 7 move toward each other, the anti-collision block 6 can abut against the rotating part 71 of the anti-collision component 7 and drive the rotating part 71 to rotate around the fixed seat 72. Specifically, the rotating part 71 moves in the direction toward the fixed seat 72 until the shading rib 711 is located between the receiving end and the transmitting end, and the sensing element 74 is triggered, and the first movement component 4 and the second movement component 5 are controlled to stop and move in opposite directions.
[0068] In order to realize that the anti-collision block 6 drives the rotating member 71 to rotate, the anti-collision block 6 abuts against the first end of the rotating member 71, and can press the rotating member 71 along the first end of the rotating member 71 toward the fixed seat 72. Preferably, the surface where the first end of the rotating member 71 abuts against the anti-collision block 6 is a guide surface. The specific shape and size of the guide surface are not specifically limited, as long as the anti-collision block 6 can be driven to rotate the rotating member 71 from the initial position to the trigger position during the movement of the anti-collision block 6 toward the anti-collision assembly 7.
[0069] In some embodiments, the limiting shaft 75 and the rotating shaft 76 may be rods with threaded sections at the ends. After the limiting shaft 75 and the rotating shaft 76 are assembled, they are fixed with fasteners 77 to prevent the limiting shaft 75 and the rotating shaft 76 from being separated from the assembly position. Optionally, the fastener 77 is a nut that matches the threaded section.
[0070] Combination Figures 5 to 7As shown, in the initial state, the rotating member 71 opens upward under the action of the reset torsion spring 73, and the limiting shaft 75 rests on the arc surface 721 at the bottom of the fixed seat 72, reaching a static equilibrium state. The shading rib 711 in the middle of the rotating member 71 is not blocked in the middle of the sensing element, and the signal is not triggered at this time.
[0071] When the anti-collision block 6 presses the guide surface of the first end of the rotating member 71, the rotating member 71 rotates around the rotating shaft 76 until the light shielding rib 711 of the rotating member 71 blocks the middle of the sensing element, and the signal is triggered.
[0072] In actual operation, when the first movement assembly 4 moves downward and / or the second movement assembly 5 moves upward (for Figure 3 and Figure 4 During the walking process (in the middle and upper and lower directions), when the anti-collision block 6 and the anti-collision component 7 do not come into contact, the two movement components can work normally; when the anti-collision block 6 contacts the rotating part 71 of the anti-collision component 7 and pushes the rotating part 71 to rotate, covering the path between the receiving end and the transmitting end of the sensing element, when the signal is triggered, the moving movement component will stop moving and move in the opposite direction. This avoids the problem of failure to work due to the collision of the movement component.
[0073] In addition, the present application also discloses a massage chair, which includes the anti-collision movement assembly disclosed in the above embodiment. Therefore, the massage chair with the anti-collision movement assembly also has all the above technical effects, which will not be described one by one here.
[0074] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0075] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
