Technical Field

[0001] The utility model relates to the field of massage devices, in particular to a front massage device and a massage chair. Background Art

[0002] Massage chairs are common human body massage machines. The frame of a massage chair usually includes a seat and a backrest. When using the massage chair, the buttocks of the human body sit on the seat, and the back and neck and shoulders lean on the backrest. The movement arranged on the side of the massage chair facing the human body moves back and forth to massage the human body.

[0003] Existing massage chairs usually have the function of massaging the neck and shoulders of the human body. At present, massage chairs for shoulder massage mainly adopt two technical solutions: one is to rely on the movement to mechanically massage the back of the neck and shoulders, and the other is to rely on air bags to squeeze and massage the left and right positions of the shoulders. In the above solutions, the massage chair can only massage the side of the human shoulder and neck facing the backrest of the massage chair, but cannot massage the side of the human body away from the backrest of the massage chair, which has limitations in use. Summary of the invention

[0018] Furthermore, the connecting arm includes a first connecting arm and a second connecting arm, the two ends of the first connecting arm are respectively pivoted to the bracket and the curved arm, the two ends of the second connecting arm are respectively pivoted to the bracket and the curved arm, and the pivot point of the first connecting arm does not coincide with the pivot point of the second connecting arm.

[0019] In this solution, the two ends of the first connecting arm are respectively pivoted to the bracket and the curved arm, the two ends of the second connecting arm are respectively pivoted to the bracket and the curved arm, and the pivot points of the first connecting arm and the second connecting arm do not overlap, and the first connecting arm, the second connecting arm, the bracket and the curved arm form a connecting rod mechanism, and the connecting rod mechanism swings to drive the curved arm to rotate. The connecting rod method is used to drive the curved arm to rotate, so that when the front massage device is in the storage state, the curved arm can move a certain distance to the rear side relative to the frame to store the curved arm, thereby reducing the overall occupied space of the massager.

[0020] Further, the pivot point between the first connecting arm and the bracket is defined as the first pivot point, the pivot point between the first connecting arm and the curved arm is defined as the second pivot point, the pivot point between the second connecting arm and the bracket is defined as the third pivot point, and the pivot point between the second connecting arm and the curved arm is defined as the fourth pivot point, the first pivot point is located on a side of the third pivot point away from the surface of the frame, and the second pivot point is located on a side of the fourth pivot point away from the surface of the frame;

[0021] The sum of the distance from the first pivot point to the second pivot point and the distance from the second pivot point to the fourth pivot point is greater than the sum of the distance from the first pivot point to the third pivot point and the distance from the third pivot point to the fourth pivot point.

[0022] In this solution, the first pivot point is located on the side of the third pivot point away from the surface of the frame, and the second pivot point is located on the side of the fourth pivot point away from the surface of the frame, that is, the first connecting arm and the second connecting arm do not cross, and the first connecting arm is located on the side of the second connecting arm away from the surface of the frame; the sum of the distance between the first pivot point and the second pivot point and the distance from the second pivot point to the fourth pivot point is greater than the sum of the distance from the first pivot point to the third pivot point and the distance from the third pivot point to the fourth pivot point, so that when the front massage device is in the storage state, the bracket, the first connecting arm, the curved arm and the second connecting arm can form a triangle, the first connecting arm and the part of the curved arm located between the second pivot point and the fourth pivot point are the two sides of the triangle, and the part of the bracket located between the first pivot point and the third pivot point is located on the same straight line as the second connecting arm and together forms the bottom side of the triangle, so that the second connecting arm is attached to the outer side of the bracket, so that the front massage device in the storage state forms a stable structure. At the same time, the angle of the curved arm rotating outward reaches the maximum, which is convenient for users to enter and exit the massager.

[0023] Optionally, the first pivot point is located on a side of the third pivot point away from the frame surface, and the second pivot point is located on a side of the fourth pivot point close to the frame surface; that is, the first connecting arm and the second connecting arm are cross-arranged to form a scissor-type linkage mechanism.

[0038] In this solution, the communication module is electrically connected to the controller, and the communication module can send instructions to the controller to control the massage chair. Specifically, when the controller does not receive the massage chair use authorization signal, it sends an anti-seat occupation execution instruction to the drive mechanism, so that the drive mechanism drives the movable arm to enclose to the side of the frame facing the human body, so that others cannot occupy the massage chair, thereby realizing the anti-seat occupation function. After using the massage chair, when the controller receives a signal that the front massage is completed, it sends a front massage device storage execution instruction to the drive mechanism, so that the movable arm leaves the side of the frame facing the human body to store the front massage device, thereby facilitating the human body to leave the massage chair.

[0039] Furthermore, the massage mechanism also includes a pressure sensing module, and the controller is also configured that: when the driving mechanism drives the movable arm to rotate from the storage state to the use state, the driving mechanism stops driving when a signal is received that the front massage pressure value meets the specified conditions.

[0040] In this solution, the pressure sensing module is used to determine whether the front massage device is rotated to the right position. When the front massage device is switched to the use state, the movable arm rotates to drive the massage mechanism to move to the side of the frame facing the human body, and the massage mechanism contacts the human body. The pressure sensing module detects the pressure of the massage mechanism contacting the human body. When the front massage pressure value detected by the pressure sensing module meets the limited conditions, a signal is sent to the controller, and the controller controls the driving mechanism to stop working to avoid the movable arm from continuing to rotate and causing discomfort to the human body. Among them, the limited condition of the front massage pressure value is the judgment pressure for judging whether the front massage device is switched to the use state, and its value is less than the tolerance limit of the human body, which can be set according to the actual use situation.

Thus, the first connecting arm 2211, the second connecting arm 2212, the bracket 210 and the curved arm 222 form a connecting rod mechanism, and the driving mechanism drives the connecting rod mechanism to swing to drive the curved arm 222 to rotate. The connecting rod method is used to drive the curved arm 222 to rotate, so that when the front massage device 200 is in the storage state, the curved arm 222 can move a certain distance to the rear side relative to the frame 100 to store the curved arm 222, thereby reducing the overall occupied space of the massager.

[0074] In addition, in other embodiments, the connecting arm 221 may also include only one of the first connecting arm 2211 and the second connecting arm 2212. In other embodiments, the connecting arm 221 may also include other numbers of straight rod-shaped members.

[0075] In this embodiment, the pivot point between the first connecting arm 2211 and the bracket 210 is defined as the first pivot point 223, the pivot point between the first connecting arm 2211 and the curved arm 222 is defined as the second pivot point 224, the pivot point between the second connecting arm 2212 and the bracket 210 is defined as the third pivot point 225, and the pivot point between the second connecting arm 2212 and the curved arm 222 is defined as the fourth pivot point 226. The first pivot point 223 is located on the side of the third pivot point 225 away from the surface of the frame 100, and the second pivot point 224 is located on the side of the fourth pivot point 226 away from the surface of the frame 100, that is, the first connecting arm 2211 and the second connecting arm 2212 do not cross, and the first connecting arm 2211 is located on the side of the second connecting arm 2212 away from the surface of the frame 100.

[0076] The sum of the distance from the first pivot point 223 to the second pivot point 224 and the distance from the second pivot point 224 to the fourth pivot point 226 is greater than the sum of the distance from the first pivot point 223 to the third pivot point 225 and the distance from the third pivot point 225 to the fourth pivot point 226. Therefore, when the front massage device 200 is in the storage state, the bracket 210, the first connecting arm 2211, the curved arm 222 and the second connecting arm 2212 can form a triangle, the first connecting arm 2211 and the part of the curved arm 222 between the second pivot point 224 and the fourth pivot point 226 are the two sides of the triangle, the part of the bracket 210 between the first pivot point 223 and the third pivot point 225 and the second connecting arm 2212 are located on the same straight line and together form the base of the triangle, so that the second connecting arm 2212 is attached to the outer side of the bracket 210, so that the front massage device 200 in the storage state forms a stable structure. At the same time, the angle of the curved arm 222 rotating outward is maximized, making it convenient for the user to enter and exit the massage chair 1000.

[0077] In addition, in other embodiments, the first pivot point 223 is located on the side of the third pivot point 225 away from the surface of the frame 100, and the second pivot point 224 is located on the side of the fourth pivot point 226 close to the surface of the frame 100; that is, the first connecting arm 2211 and the second connecting arm 2212 are cross-arranged to form a scissor-type linkage mechanism.

[0078] The movable arm 220 is provided with an outer shell 227, which covers the side of the movable arm 220 away from the human body, and is in an arc shape. The outer shell 227 covers the side of the movable arm 220 that is away from the human body (i.e., the outer side of the movable arm 220), so that the rotating joint of the movable arm 220 is not easily exposed to the outside, making the rotation of the movable arm 220 more stable and safe. At the same time, the arc-shaped outer shell 227 can make the transition between the front massage device 200 and the massager natural, and the outer side of the front massage device 200 is more beautiful.

[0079] In this embodiment, the massage mechanism 230 includes at least one of an airbag mechanism, a voice coil vibration massage device, and a heating mechanism. Preferably, the massage mechanism 230 uses an airbag mechanism, so that the airbag mechanism can be deflated and contracted when the front massage device 200 is in the storage state, further reducing the space occupied by the front massage device 230 in the storage state, while making it convenient for users to enter and exit the massage chair 1000.

[0080] In this embodiment, the massage mechanism 230 can be set at the end of the movable arm 220 away from the bracket 210 so as to be adjustable forward and backward and / or left and right relative to the movable arm 220, so that the position of the massage mechanism 230 relative to the movable arm 220 can be adjusted to meet the usage requirements of different users.

[0081] In this embodiment, the massage mechanism 230 also includes a pressure sensing module. The controller is electrically connected to the pressure sensing module. When the driving mechanism drives the movable arm 220 to rotate from the storage state to the use state, the massage mechanism 230 contacts the human body, and the pressure sensing module detects the pressure of the massage mechanism in contact with the human body 230 (front massage pressure). The pressure sensing module determines whether the front massage device is rotated into place. When the front massage pressure value detected by the pressure sensing module meets the limiting conditions, a signal is sent to the controller. The controller receives the signal that the front massage pressure value meets the limiting conditions, and controls the driving mechanism to stop driving to avoid the movable arm from continuing to rotate and causing discomfort to the human body. Among them, the limiting condition of the front massage pressure value is the judgment pressure for judging whether the front massage device is switched to the use state, and its value is less than the tolerance limit of the human body. It can be set according to the actual use situation.

[0082] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
