Description

Technical Field

[0001] The invention relates to the technical field of massage chairs, and in particular to a connecting rod opening and closing head cover and a massage chair. Background Art

[0002] With the development of the Internet of Things and mobile payment technologies, as well as changes in mass consumption and leisure habits, shared massage chairs have transformed from a new thing to an indispensable part of public places such as airports, high-speed rail stations, and shopping malls.

[0003] In order to improve the comfort of massage chairs, multiple usage modes are designed for massage chairs so that users can switch between sitting and lying. In public places, the widespread deployment of shared massage chairs often faces the problem of ineffective occupancy, resulting in the massage chairs that should provide services to more people failing to play their true value of sharing.

[0004] In order to improve the privacy of massage chairs, the demand for equipping massage chairs with head covers is increasing. At present, massage chairs with flip head covers are mainly realized by manually pulling and rotating the head covers or by driving the motor to pivot; for example, patent announcement number CN113143671B discloses "a massage chair with a flip head cover and a massage chair with a flip head cover", which realizes the flipping of the head cover through a push rod to provide a private space for the user.

[0005] At present, the switching structures of the head cover and the massage chair are independent of each other and use their own power systems, which not only increases the cost but also reduces the efficiency of use. Therefore, it is necessary to integrate the switching structure of the head cover and the massage chair to achieve more efficient operation and save costs. Summary of the invention

[0006] In view of the deficiencies in the prior art, the present invention provides a connecting rod opening and closing head cover and a massage chair to solve the above problems.

[0007] The present invention provides the following technical solutions:

[0008] A connecting rod opening and closing head cover, comprising:

[0009] A base frame, a first link, a frame and a second link are sequentially connected to form a four-link structure;

[0010] A telescopic component, the two ends of which are respectively connected to the base frame and the frame;

[0011] A head cover is hinged on the frame;

[0012] A first linkage rod, one end of which is hinged to the third link rod, and the other end of which is connected to the head cover via a second linkage rod.

[0013] Preferably, the frame includes a backrest portion and a seat portion.

[0014] Preferably, an auxiliary frame is hinged on the seat portion of the frame, and a second telescopic component for driving the auxiliary frame to rotate is installed on the frame.

[0015] Preferably, a third connecting rod is hinged on the seat portion, the output end of the second telescopic assembly is connected to the third connecting rod, a fourth connecting rod is hinged on the third connecting rod, and a fifth connecting rod is connected between the fourth connecting rod and the auxiliary frame.

[0016] Preferably, the frame is fixedly connected to the hood.

[0017] Preferably, one end of the second linkage rod is rotatably connected to the hood via a hinge shaft, a hinge hole is provided on the hood, and the hinge shaft and the hinge hole cooperate to realize the rotation of the hood relative to the frame.

[0018] Preferably, the head cover is provided with a limiting groove extending circumferentially from the hinge hole, and the hinge shaft is provided with a limiting plate movable in the limiting groove.

[0019] Preferably, a space is reserved between the frame and the hood for the first linkage rod to move.

[0020] Preferably, a telescopic rod is connected between the head cover and the frame.

[0021] A massage chair comprises the connecting rod opening and closing head cover.

[0022] The present invention has the following beneficial technical effects:

[0023] The first telescopic component of the present invention is not only used to drive the frame to rotate a certain angle to switch the frame between sitting and lying modes, but also, when the frame rotates to the lying mode, the head cover is driven by the first and second linkage rods to rotate and close, thereby providing a private space for the user.

[0024] When the frame rotates to the sitting mode, the hood is driven to rotate and open via the first and second linkage rods, thereby providing a wider field of vision for the user and facilitating the user to stand up.

[0025] The frame and the head cover are cleverly connected through the first and second linkage rods, which can reduce the use of driving components and reduce costs.

[0026] When the massage chair is not in use, the frame rotates to the lying mode. This setting will prevent the seat occupant from easily occupying the seat; at the same time, the head cover in the closed state further reduces the space, increasing the difficulty of occupying the seat, thereby achieving the purpose of preventing seat occupation.

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] A connecting rod opening and closing head cover is used in massage chairs, such as Figure 1-3 As shown:

[0043] It includes a base frame 1, a first connecting rod 2, a second connecting rod 3 and a frame 4, the base frame 1 is relatively fixed; the lower end of the first connecting rod 2 is hinged to the right part of the base frame 1, and the upper end of the first connecting rod 2 is hinged to the right part of the seat part 402 of the frame 4; the lower end of the second connecting rod 3 is hinged to the left part of the base frame 1, and the upper end of the second connecting rod 3 is hinged to the left part of the seat part 402 of the frame 4 (or the lower part of the backrest 401); thereby realizing that the base frame 1, the first connecting rod 2, the frame 4, and the second connecting rod are connected in sequence to form a four-link structure.

[0044] The first telescopic assembly 300 can be a telescopic cylinder or an electric push rod. The fixed end of the first telescopic assembly 300 is hinged to the right part of the base frame 1 , and the movable end of the first telescopic assembly 300 is hinged to the right part of the seat part 402 of the frame 4 .

[0045] like Figure 7 As shown, the frame 4 includes a backrest portion 401 and a seat portion 402 , which form an L-shaped structure. During use, the backrest portion 401 is used to support the user's back, and the seat portion 402 is used to support the user's buttocks.

[0046] The lower end of the first linkage rod 5 is hinged to the middle and upper part of the second linkage rod 3, and the upper end of the first linkage rod 5 is hinged to the lower end of the second linkage rod 6. The first linkage rod 5 is relatively located in the space between the frame 4 and the hood 100, and the length of the first linkage rod 5 is almost the same as the length of the backrest 401.

[0047] The hood 100 is fixed on the frame 4, and the two adjacent sides of the hood 100 are open (the upper and right sides); the head cover 200 is relatively hinged at the upper end of the frame 4 / hood 100.

[0048] The upper end of the second linkage rod 6 is hinged to the head cover 200 .

[0049] Working principle:

[0050] like Figure 3 As shown in the sitting mode, the head cover 200 is in the open state, and the first telescopic component 300 extends to drive the four-bar structure to follow the movement, thereby transforming the originally nearly vertical L-shaped structure skeleton 4 into an inclined setting, so that the originally nearly horizontal seat part 402 rotates upward, and the originally nearly vertical backrest part 401 rotates downward, thereby realizing the transformation from the sitting mode to the lying mode.

[0051] During this process, the rotation of the second connecting rod 3 drives the head cover 200 to rotate (the rotation angle is small at about 20°) through the first linkage rod 5 and the second linkage rod 6 to become a closed state. In this state, the head cover 200 is relatively closed to the upper side opening of the hood 100.

[0052] The frame 4 in the lying mode and the head cover 200 in the closed state provide a relatively independent private space for the user.

[0053] When it is necessary to stand, the first telescopic component 300 is controlled to shorten and reset, driving the four-bar structure to follow the movement, so that the inclined frame 4 rotates to a nearly vertical state. During this process, the head cover 200 opens the upper opening of the hood 100 relatively. The vertical frame 4 and the open head cover 200 make it convenient for the user to stand up and leave the massage chair.

[0054] When not in use, the first telescopic assembly 300 is in an extended state, the frame 4 is in a tilted state (lying mode), the hood 200 is relatively in a closed state with respect to the upper opening of the hood 100, and the tilted frame 4 / hood 100 and the hood 100 with only the right side opening can prevent unused users from easily entering the interior of the hood 100.

[0055] Embodiment 2: includes all the contents of Embodiment 1, except that Figure 4-6 As shown:

[0056] A hinge shaft 61 is fixedly disposed at the upper end of the second linkage rod 6, and the hinge shaft 61 is rotatably connected and matched with the hood 100, and a limit plate 62 is disposed on the hinge shaft 61;

[0057] The hood 200 is provided with a hinge hole 201, and the hinge shaft 61 is inserted into the matching hinge hole 201. The hood 200 is hingedly matched with the hood 100 / frame 4 through the cooperation of the hinge hole 201 and the hinge shaft 61.

[0058] A limiting groove 202 extending circumferentially with the hinge hole 201 as the center is provided on the head cover 200, and the limiting plate 62 on the hinge shaft 61 is relatively arranged in the limiting groove 202. When the hinge shaft 61 rotates relatively in the coaxial hinge hole 201, the limiting plate 62 follows and rotates relatively in the limiting groove 202. The rotation stroke of the limiting plate 62 in the limiting groove 202 is small (approximately 22°).

[0059] During the movement of the four-bar structure, the second link rod 3 drives the first link rod 5 to rotate accordingly, and the rotation of the first link rod 5 drives the second link rod 6 to rotate around the axis of the hinge shaft 61. During this process, the limit plate 62 first rotates to the limit position in the limit groove 202, and then drives the head cover 200 to rotate accordingly.

[0060] The limiting plate 62 can move in the limiting groove 202 to a certain angle. When the user lies inside the hood 100, the hood 200 can be manually pushed up to a certain angle to facilitate the user to observe the external environment; after the hand is released, it will automatically recover under the action of gravity.

[0061] Embodiment 3: includes all the contents of Embodiment 1 / 2, except that, Figure 4 As shown:

[0062] A telescopic rod 7 is connected between the middle part of the hood 200 and the upper end of the frame 4. When the hood 200 rotates relative to the frame 4, the telescopic rod 7 follows and extends. The telescopic rod 7 can be a spring-type telescopic rod that tends to extend under normal conditions. When the hood 200 is in an open state, the telescopic rod 7 provides support for it.

[0063] Embodiment 4: includes all the contents of Embodiment 3, except that, Figure 7 As shown:

[0064] The right end of the seat portion 402 of the skeleton 4 is hinged with the auxiliary frame 8 and the third connecting rod 42, the fixed end of the second telescopic component 41 is hinged at the lower part of the seat portion 402, the movable end of the second telescopic component 41 is hinged to the lower end of the third connecting rod 42, the middle part of the third connecting rod 42 is hinged with the third connecting rod 43, the lower end of the third connecting rod 43 is hinged with the fifth connecting rod 44, and the right end of the fifth connecting rod 44 is hinged at the middle part of the auxiliary frame 8.

[0065] The extension and retraction of the second telescopic assembly 41 drives the third connecting rod 42 to rotate relative to the seat portion 402 . The rotation of the third connecting rod 42 drives the auxiliary frame 8 to rotate relative to the seat portion 402 via the fourth connecting rod 43 and the fifth connecting rod 44 .

[0066] Thereby, the auxiliary frame 8 is rotated to be substantially flush with the seat portion 402 , or the auxiliary frame 8 is rotated to be substantially perpendicular to the seat portion 402 .

[0067] The auxiliary frame 8 can be used to expand the area of ​​the seat portion 402 or to support the legs. The area of ​​the seat portion 402 can be designed to be small and not conducive to sitting, so as to prevent the occupant from occupying the seat; in normal use, the area of ​​the seat portion 402 is expanded by the auxiliary frame 8 to enable the user to sit normally.

[0068] When the area design of the seat portion 402 is normal, the auxiliary frame 8 can be used to support the legs.

[0069] The above-mentioned embodiments only express the specific implementation of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
