Description

Technical Field

[0001] The utility model relates to a massage chair, more particularly to a massage chair with an anti-seat-occupancy function. Background Art

[0002] Shared massage chairs have been installed in many public places, providing help for people's leisure and physical and mental relaxation; with the widespread popularity and large-scale deployment of shared massage chairs in public places, there is a common phenomenon of ineffective occupation, which makes it impossible for massage chairs that should provide massage services to more people to truly play the role of shared massage. For people who sit on massage chairs for a long time without scanning the code for massage, this seriously affects the revenue of shared massage chairs and has an adverse impact on the development of shared massage chairs. Therefore, a way to prevent unreasonable seat occupation is needed.

[0003] A patent document with publication number CN220404359U has been retrieved. Its title is a massage chair with an anti-seat occupation function. Paragraph

[28] of its specification states that "the anti-seat occupation mechanism includes a lifting frame 2 and a driving member 3. The lifting frame 2 is rotatably arranged at the front end of the massage chair body 1 through a pin shaft b. The lifting frame 2 is provided with at least one sensing device 4. The sensing device 4 detects whether the seat is occupied. The lifting frame 2 is provided with a notch 21 at a position corresponding to the buttocks of the human body. One end of the driving member 3 is hinged to the massage chair body 1, and the other side of the driving member 3 is hinged to the lifting frame 2. Specifically, the driving member 3 is an electric push rod, and the output end of the driving member 3 is hinged to the lifting frame 2."

[0004] The above solution has a technical defect, that is, the lifting of the lifting frame 2 is driven by the moving part 3, that is, the electric push rod. If a foreign object falls from the bottom of the pop-up lifting frame 2, if the lifting frame 2 is forcibly reset and falls under the drive of the electric push rod, the object on the lifting frame 2 will be pinched and broken. Utility Model Content

[0005] The purpose of the utility model is to provide a massage chair with an anti-seat occupation function. When the flip frame falls and resets, gravity is used as the power source. The flip frame only lightly presses on the objects, avoiding the possibility of being pinched by the driving parts when there are foreign objects under the flip frame, thereby achieving an anti-pinch effect.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A massage chair with anti-seat occupation protection includes a seat body and an anti-seat occupation protection mechanism. The anti-seat occupation protection mechanism includes a flip frame hinged on the seat body and a telescopic drive member that drives the flip frame to rotate up and down. The flip frame is located above the seat surface of the seat body. The flip frame is fixed with a downward first connecting rod, the lower end of the first connecting rod is hinged with a second connecting rod, the lower end of the second connecting rod is hinged to the telescopic rod of the telescopic drive member, and the main body of the telescopic drive member is hinged to the seat body; the upper end of the second connecting rod is fixed with an extension portion, and the extension portion and the first connecting rod rotate in the same vertical plane; when the telescopic drive member is in the first extended state, the extension portion contacts the first connecting rod to drive the flip frame to rotate upward and open; when the telescopic drive member is in the second extended state, the extension portion and the first connecting rod are separated, and the flip frame rotates downward and resets under gravity.

[0008] By adopting the above technical solution, the reset power source of the traditional flip frame is changed. The traditional anti-seat reset adopts a power push rod to pull and reset. Therefore, the flip frame is reset and falls under the drive of the power push rod. If there is an object under the flip frame at this time, it will be pinched due to the large driving force of the power push rod. The present design overcomes this defect. Through the setting of the second connecting rod, the telescopic drive member plays a power driving role when the flip frame is rotated and popped up. When the flip frame falls, the telescopic rod of the telescopic drive member is quickly separated and retracted, and the flip frame relies on its own gravity to rotate and fall. At this time, if there is an object under the flip frame, it only needs to be pressed by the flip frame cover to withstand its gravity and will not be pinched, thereby achieving a good anti-pinching effect.

[0009] Preferably, the telescopic driving member is a power push rod.

[0010] By adopting the above technical solution, the power push rod is a common electric push rod, which is convenient to use and has stable performance; the electric push rod is also called a linear drive, which is mainly a new type of linear actuator composed of a motor push rod and a control device.

[0011] Preferably, the lower end of the first connecting rod is provided with a receiving groove for the protruding portion to freely enter and exit.

[0012] By adopting the above technical solution, the space provided in the receiving groove facilitates the insertion of the extension portion of the second connecting rod, which can reduce the space occupied by the internal space of the massage chair when the two are pushed together. Secondly, the insertion of the extension portion into the receiving groove also prevents the first connecting rod from swinging left and right relative to the second connecting rod, making the conflict relationship between the first connecting rod and the second connecting rod more stable.

[0013] Preferably, the cross section of the accommodating groove is concave.

[0014] By adopting the above technical solution, the structure is simple and the production is convenient.

[0015] Preferably, the upper surface of the flip frame is hinged with a seat plate, a press-type trigger switch is provided between the flip frame and the seat plate, and a support spring is provided between the flip frame and the seat plate; when the seat plate presses down the trigger switch, the telescopic drive member starts to the first extended state; when the support spring supports the seat plate to separate the trigger switch, the telescopic drive member starts to the second extended state.

[0016] By adopting the above technical solution, the trigger structure of the turnover frame and the seat plate is a relatively common structure with stable performance.

[0017] Preferably, the turnover frame is a U-shaped frame, the seat plate is a U-shaped plate, and the U-shaped openings of the seat plate and the turnover frame are aligned.

[0018] By adopting the above technical solution, the U-shaped openings are aligned to leave space for the massage rollers on the buttocks below.

[0019] Preferably, a positioning column is provided on the lower surface of the flip frame, and a positioning groove is provided on the base body for the positioning column to be inserted into after the flip frame is rotated downward and reset.

[0020] By adopting the above technical solution, the flip frame and the seat body are only hinged with one connecting piece, which has poor stability. The vibration during massage in the massage chair can easily drive the flip frame to move, which can easily cause the user experience of sitting on the seat to decrease. This design adopts the interlocking and limiting effect of the positioning column and the positioning groove, which reduces the occurrence of the flip frame moving back and forth on the seat body and improves the comfort of massage.

[0021] Preferably, the positioning column includes an upper tube and a lower column, the lower column slides in the upper tube, and an inner spring is provided in the upper tube to support the lower column to extend.

[0022] By adopting the above technical solution, the positioning column is also facing the base body, which makes it easy to squeeze the customer when the flip frame falls, reduce rigid collision through buffering, and reduce damage to items during squeezing. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The following is combined with Figure 1 -Attached Figure 7 The utility model is described in further detail.

[0036] Example 1, a massage chair with an anti-seat occupation function, referring to Figures 1-6 , including a seat body 1 and an anti-seat occupation mechanism 2, the seat body 1 includes a backrest and a riding base frame, and a massage device is provided in the backrest and the riding base frame.

[0037] An anti-seat occupation mechanism 2 is installed on the riding chassis;

[0038] The anti-seat occupation mechanism 2 includes a flip frame 24 hinged to the seat body 1; the flip frame 24 is located above the seat surface of the seat body 1.

[0039] A seat plate 27 is hingedly connected to the upper surface of the flip frame 24;

[0040] The flip frame 24 is a U-shaped frame, the seat plate 27 is a U-shaped plate, and the U-shaped openings of the seat plate 27 and the flip frame 24 are aligned. This design facilitates the massager of the buttocks of the massage chair to perform massage actions from the gap position of the U-shaped plate.

[0041] The seat plate 27 and the two ends of the flip frame 24 are connected by a rotating shaft.

[0042] The middle position of the turnover frame 24 is rotatably connected to the riding base of the seat body 1 through another rotating shaft. The connection position is at the outer edge of the seat body 1, so the turnover frame 24 can be freely rotated outward to open or close.

[0043] The flip frame 24 is fixed with a downward first connecting rod 21, and the lower end of the first connecting rod 21 is hinged to the second connecting rod 22. A telescopic driving component 25 is installed under the base body 1. The telescopic driving component 25 is a power push rod. The cylinder body of the power push rod is hinged on the base body 1. The power push rod includes a telescopic rod 26, and the telescopic rod 26 is hinged to the lower end of the second connecting rod 22.

[0044] Therefore, the rotation of the turning frame 24 can be promoted by the telescopic action of the power push rod.

[0045] The upper end of the second connecting rod 22 is fixed with an extension portion 23, and the extension portion 23 and the first connecting rod 21 rotate in the same vertical plane. The lower end of the first connecting rod 21 is provided with a receiving groove 3 for the extension portion 23 to freely enter and exit. The cross section of the receiving groove 3 is concave.

[0046] Figure 4 In state b, when the extension portion 23 rotates and contacts the first link 21, the second link 22 drives the first link 21 to rotate;

[0047] Figure 4 In state c, when the extension portion 23 rotates away from the first connecting rod 21, the first connecting rod 21 and the second connecting rod 22 maintain a rotational connection, and the power push rod does not apply a pushing force to the first connecting rod 21.

[0048] A push-type trigger switch 28 is provided between the flip frame 24 and the seat plate 27. The trigger switch 28 is a push switch.

[0049] When the seat plate 27 presses the trigger switch 28, the trigger switch 28 electrically controls the power push rod to retract, that is, the telescopic driving member 25 is activated to the first extended state;

[0050] When the support spring 29 props up the seat plate 27 to separate the trigger switch 28, the seat plate 27 separates the trigger switch 28, and the trigger switch 28 electrically controls the power push rod to extend, and the telescopic driving member 25 is started to the second extended state.

[0051] A support spring 29 is provided between the flip frame 24 and the seat plate 27. The support spring 29 pushes up the seat plate 27 so that there is a gap between the trigger switch 28 and the seat plate 27. When someone sits on the seat plate 27, the support spring 29 is squeezed; when the person leaves the seat plate 27, the support spring 29 pushes up the seat plate 27 again to keep it separated.

[0052] When the telescopic driving member 25 is in the first extended state, the extended portion 23 abuts against the first connecting rod 21 to drive the flip frame 24 to rotate upward and open;

[0053] When the telescopic driving member 25 is in the second extended state, the extending portion 23 is separated from the first connecting rod 21, and the turnover frame 24 rotates downward and resets under gravity.

[0054] The lower surface of the flip frame 24 is provided with a positioning column 5, and the base body 1 is provided with a positioning groove 4; Figure 1 When the flip frame 24 rotates downward to the seating position, Figure 2 , the positioning column 5 is inserted into the positioning groove 4.

[0055] Working principle:

[0056] A design is adopted in which a second connecting rod 22 is added, and the extension portion 23 at the upper end of the second connecting rod 22 and the first connecting rod 21 maintain a counter-rotation relationship as follows:

[0057] Figure 5 , the second connecting rod 22 rotates counterclockwise, and the extension portion 23 and the first connecting rod 21 come into conflict with each other.

[0058] Figure 6 , the second connecting rod 22 rotates clockwise, and the extension portion 23 and the first connecting rod 21 are separated from each other.

[0059] When the massage chair is in normal use, the trigger switch 28 is in a disabled state. For example, when the user scans the code to make a purchase, the trigger switch 28 is disabled, and the anti-seat occupation function will not be triggered. When the massage chair is occupied, for example, when the user sits on the massage chair without scanning the code to make a purchase, the trigger switch 28 is in an enabled state. The activated trigger switch 28 will send a signal of the corresponding state to the power push rod.

[0060] Therefore, the normal state of the overturning frame 24 is as follows Figure 4 a;

[0061] When someone occupies the massage chair, the seat plate 27 is pressed down, the trigger switch 28 is pressed down, the power push rod retracts, and the flip frame 24 rotates to the position as shown in FIG. Figure 4 b;

[0062] When no one is on the occupied seat, the seat plate 27 is reset under the support spring 29, the trigger switch 28 is reset, and the power push rod is extended. At this time, the overturning frame 24 loses the top holding force of the telescopic rod 26 and falls under the action of gravity.

[0063] The advantage of this design is clear, that is, it reduces the possibility of objects or creatures being strongly pinched or damaged by the reset turning frame 24. Since the turning frame 24 relies on its own gravity to fall, the clamping force generated by its fall is relatively small, thus greatly avoiding the occurrence of strong pinching or damage by the turning frame 24.

[0064] Example 2, a massage chair with an anti-seat occupation function, which is different from Example 1 in that Figure 7 The positioning column 5 includes an upper tube 6 and a lower column 7. The lower column 7 slides in the upper tube 6. The upper tube 6 is provided with an inner spring 8 that supports the lower column 7 to extend. The role of this design is to play an elastic buffer to avoid the rigid impact of the positioning column 5.

[0065] The above description is merely a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiment. All technical solutions based on the concept of the present invention are within the scope of protection of the present invention. It should be noted that for those skilled in the art, certain improvements and modifications that do not depart from the principles of the present invention should also be considered within the scope of protection of the present invention.
