Description

Technical Field

[0001] The utility model belongs to the technical field of sofa structures, and in particular relates to a sofa with a massage function. Background Art

[0002] The massage structure of the common existing massage sofa is generally installed on the backrest plate. Moreover, the conventional sofa massage structure generally includes: a limit frame, a jacking ball head, and a driving structure.

[0003] The function of the limit frame is to prevent the lifting ball head and its installation structure from shifting up, down, left, and right, and can only move forward to trigger massage and retract backward to cancel massage. The above-mentioned installation structure is the force transmission position between the driving structure and the lifting ball head, so that all the lifting ball heads can move forward one by one, row by row, column by column, or in a more complex and scientific order to trigger massage.

[0004] At this point, the jacking ball head presses the entire back of the occupant in an orderly manner, so that the sofa massage function can be effectively realized.

[0005] For example, a Chinese utility model patent with authorization announcement number CN220174796U and authorization announcement date 2023.12.15 discloses a sofa with a massage function, including a sofa fixed shell, the inner cavity side wall of the sofa fixed shell is fixedly connected to a support fixing plate by bolts, the top of the support fixing plate is fixedly connected to two groups of support fixing frames by bolts, the inner cavity side plates of the two groups of support fixing frames are respectively fixedly connected to several groups of evenly distributed fixing rings, the inner cavity side walls of the several groups of fixing rings are rotatably connected to a connecting fixing rod through a rotating shaft, and the surface of the connecting fixing rod is fixedly connected to several groups of evenly distributed rubber massage balls by bolts.

[0006] The general structural principle and advantages of the massage function sofa in this utility model patent are as follows: the massage function of the sofa is realized through the cooperation of transmission control components such as hydraulic telescopic rods, which improves its comfort level, and the overall structural design is relatively simple, which facilitates subsequent repair and maintenance.

[0007] However, in actual use, the massage sofa still has at least the following two shortcomings, which are also the technical problems to be solved by the present utility model, namely:

[0008] 1. When the power is off, the extension of the rubber massage balls of the sofa is uncertain. Most of them may be retracted, or they may be extended out of order, so it is impossible to provide a comfortable and effective passive massage effect for the occupants.

[0009] 2. The order of extension and retraction between the rows of rubber massage balls is fixed. For example, the rubber massage balls in two adjacent rows are always "one extension and one retraction", which greatly reduces the diversity and scientificity of the massage method.

[0010] So in summary, there is an urgent need for a new type of massage sofa with a relatively scientific passive massage effect and a more flexible and changeable active extended massage function. Utility Model Content

[0011] The utility model provides a sofa with a massage function, which can be provided with a front groove, an elastic coating, a fixed hole plate unit, a ball spring rod unit, a back fitting fixed plate unit, and a ball ejection strip unit on a backrest plate, so that:

[0012] 1. When the ball ejector unit is closed, the back fitting fixing plate unit can provide a relatively close-fitting protrusion fixing effect to the ball spring rod unit, ensuring that the sofa has a relatively scientific passive massage effect;

[0013] 2. A single ball ejector bar unit can eject the ball spring rod units in the same column or row outwards. Several ball ejector bar units are independent of each other, ensuring that the active extension massage function is more flexible and changeable.

[0014] The technical solution adopted by the utility model to solve the above-mentioned problem is: a sofa with a massage function, the structure of which includes a backrest plate, a front groove, and an elastic coating, and also includes a fixed hole plate unit arranged in the front groove, a ball spring rod unit inserted into the fixed hole plate unit, a back fitting fixed plate unit arranged in the front groove and located on the inner side of the fixed hole plate unit and used to support the ball spring rod unit, and a plurality of ball ejection strip units sleeved on the ball spring rod unit.

[0015] A further preferred technical solution is that the fixed orifice plate unit comprises a rectangular plate with two ends arranged on the inner side of the front slot, and a mounting hole arranged on the rectangular plate and used for inserting the ball spring rod unit.

[0016] A further preferred technical solution is that the ball-spring rod unit includes a rod body inserted into the mounting hole, a massage ball arranged on the outer end of the rod body, a fixed ring arranged on the rod body and located on the outer side of the rectangular plate, and a tension spring sleeved on the rod body, connecting the rectangular plate and the fixed ring and used to press the inner end of the rod body onto the back-fitting fixed plate unit.

[0017] A further preferred technical solution is that the back-fitting fixing plate unit includes a flat plate with both ends arranged on the inner side of the front groove and used to support the rod body, and an outwardly protruding arc plate arranged on the flat plate and used to support the rod body.

[0018] A further preferred technical solution is that: the number of the flat plates is two, which are respectively arranged at the upper and lower sides of the outwardly protruding arc-shaped plate.

[0019] A further preferred technical solution is that the ball ejection strip unit includes a rectangular strip plate arranged in the front groove and located outside the fixed ring, an opening arranged on the rectangular strip plate and used to pass through the rod body, and a pulling plate arranged on the rectangular strip plate and used to connect the fixed ring.

[0020] A further preferred technical solution is that the ball ejection strip unit also includes two permanent magnets respectively arranged at the two ends of the rectangular strip plate, and an electromagnet arranged in the front groove and respectively located at the two sides of the fixed hole plate unit and the back bonding fixed plate unit, and used to push the permanent magnet outward.

[0021] A further preferred technical solution is that the ball ejector strip unit also includes a cylinder arranged in the front groove and located at both sides of the fixed hole plate unit and the back bonding fixed plate unit, and used to push the end of the rectangular strip plate outward.

[0022] A further preferred technical solution is that the long side direction of the rectangular strip is horizontal.

[0023] A further preferred technical solution is that: the massage ball is provided with a threaded groove for screwing the rod body. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0037] As attached Figure 1-8 As shown, a sofa with massage function comprises a backrest plate 11, a front groove 12, and an elastic coating 13, and also comprises a fixing hole plate unit 1 arranged in the front groove 12, a ball spring rod unit 2 inserted into the fixing hole plate unit 1, a back fitting fixing plate unit 3 arranged in the front groove 12 and located on the inner side of the fixing hole plate unit 1 and used for supporting the ball spring rod unit 2, and a plurality of ball ejection strip units 4 sleeved on the ball spring rod unit 2.

[0038] In this embodiment, the backrest board 11 and the seat board 14 are fixedly connected, and the word "front" of the front slot 12 means that the side faces the occupant.

[0039] The elastic coating 13 is made of commonly available leather or elastic rubber, and needs to be removed from the front slot 12 when the massage structure is disassembled, assembled, or repaired. Therefore, the elastic coating 13 is bonded to the front slot 12 by Velcro or connected by a zipper.

[0040] In addition, the fixed hole plate unit 1 and the back-fitting fixed plate unit 3 are symmetrically connected to the front groove 12 on two sides, and space is left between the other two sides and the side surfaces of the front groove 12 for installing the driving structure of the ball ejection strip unit 4.

[0041] Secondly, the ball spring bar units 2 are arranged horizontally and vertically, and are independent of each other, and the ball ejector bar units 4 are also independent of each other horizontally or vertically. Then the driving structure of the ball ejector bar unit 4 is combined with a simple controller for the common circuit on and off, and finally ensures that all the ball spring bar units 2 can be extended and retracted as needed, achieving a full and flexible massage effect on the sofa backrest.

[0042] In addition, the lengths of all the ball spring rod units 2 are the same, but the back fitting fixing plate unit 3 provides an outward protruding portion, so that all the ball spring rod units 2 can form a generally "straight on the top and curved on the bottom" curved profile, which can better fit the back of the occupant compared to the integral straight plate support method. At this time, even if the ball ejection bar unit 4 is not turned on, the massage sofa can provide the occupant with a passive, comfortable, and relatively scientific massage effect. If the occupant twists his back slightly, the above passive massage effect will be better.

[0043] Finally, the conventional backrest board 11 is generally not solid. Therefore, the front slot 12 can be composed of five boards, namely, upper, lower, left, right and inner boards, and the whole backrest board 11 is a frame structure plus the above five board slot structures.

[0044] The fixed orifice plate unit 1 comprises a rectangular plate 101 with two ends arranged on the inner side of the front slot 12 , and a mounting hole 102 arranged on the rectangular plate 101 and used for inserting the ball spring rod unit 2 .

[0045] In this embodiment, the upper and lower sides of the rectangular plate 101 are fixedly connected to the front slot 12, and the mounting holes 102 are evenly spaced in a linear arrangement, for example, 6 rows and 5 columns.

[0046] The ball spring rod unit 2 includes a rod body 201 inserted into the mounting hole 102, a massage ball 202 arranged on the outer end of the rod body 201, a fixed ring 203 arranged on the rod body 201 and located on the outer side of the rectangular plate 101, and a tension spring 204 sleeved on the rod body 201, connecting the rectangular plate 101 and the fixed ring 203, and used to press the inner end of the rod body 201 onto the back fitting fixed plate unit 3.

[0047] In this embodiment, the main body of the ball spring rod unit 2 is made of hard plastic, and the massage ball 202 is made of relatively soft rubber.

[0048] The function of the tension spring 204 is to:

[0049] First, when the driving structure of the ball ejection strip unit 4 is not turned on, the rod body 201 is stably pressed on the back fitting fixing plate unit 3, so that the curved contour of the back fitting fixing plate unit 3 is the contour of the massage ball 202, ensuring that the sofa can provide active and passive massage effects that fit the back better;

[0050] Second, when the driving structure of the ball ejection strip unit 4 is turned on, the driving force for extending the massage ball 202 outward is much greater than the inward pulling force of the tension spring 204, ensuring that the massage ball 202 can be extended to the outside of the front slot 12 as needed.

[0051] The back-fitting fixing plate unit 3 includes a flat plate 301 with both ends arranged on the inner side of the front slot 12 and used to support the rod body 201 , and an outwardly protruding arc plate 302 arranged on the flat plate 301 and used to support the rod body 201 .

[0052] In this embodiment, even when the ball ejection strip unit 4 is closed, all of the massage balls 202 protrude from the outside of the front groove 12, and a lower arc-shaped protruding back fitting area is formed through the outwardly protruding arc plate 302, ensuring that the passive massage effect at this time and the subsequent active massage effect can better fit the back.

[0053] The installation method of the back-fitting fixing plate unit 3 is the same as that of the fixing hole plate unit 1 , which is also fixed up and down and leaves space on the left and right for installing the above-mentioned driving structure, that is, the driving structure of the ball ejection strip unit 4 .

[0054] There are two flat plates 301 , which are respectively disposed at the upper and lower sides of the outwardly protruding arc-shaped plate 302 .

[0055] In this embodiment, the lower protrusion of the back-fitting fixing plate unit 3 is specifically in the following two ways:

[0056] First, it is divided into two areas, the lower area is the outwardly protruding arc plate 302, corresponding to the waist area of ​​the back, and the upper area is corresponding to the back area;

[0057] Second, it is divided into three areas: upper, middle and lower. The middle area is the arc-shaped plate 302 protruding outward, corresponding to the waist area of ​​the back, the upper area corresponds to the back area, and the lower area corresponds to the sacrum area.

[0058] It is generally believed that the second method is better, so that the back massage effect is more comprehensive. At this time, the upper flat plate 301, the middle outwardly protruding curved plate 302, and the other flat plate 301 below are connected in sequence, or can be bent and formed by a whole plate.

[0059] The ball ejection strip unit 4 includes a rectangular strip plate 401 arranged in the front groove 12 and located outside the fixed ring 203, an opening 402 arranged on the rectangular strip plate 401 and used to pass through the rod body 201, and a pulling plate 403 arranged on the rectangular strip plate 401 and used to connect the fixed ring 203.

[0060] In this embodiment, the length of the rectangular strip 401 is greater than the lateral side dimensions of the fixed hole plate unit 1 and the back-fitting fixed plate unit 3. The former is exposed at both ends of the latter, and the exposed portion is used to install the above-mentioned driving structure.

[0061] At this point, the massage balls 202 arranged in rows and columns can be extended outwards in rows or columns for massage, and there is no restriction on the order and amplitude of the extending action, thereby ensuring that the active massage effect is more flexible and efficient.

[0062] The ball ejection strip unit 4 also includes two permanent magnets 404 respectively arranged at the two ends of the rectangular strip plate 401, and an electromagnet 405 arranged in the front groove 12 and respectively located at the two sides of the fixed hole plate unit 1 and the back bonding fixed plate unit 3, and used to push the permanent magnet 404 outward.

[0063] In this embodiment, the combination of the permanent magnet 404 and the electromagnet 405 is one of the implementation methods of the above-mentioned driving structure. Among them, the current size and power-on time of the latter are adjustable, and the initial magnetic strength of the former is also optional, which ultimately ensures that the massage ball 202 can be extended in a more diversified massage manner.

[0064] The ball ejector strip unit 4 also includes a cylinder 406 which is arranged in the front groove 12 and is located at both sides of the fixed hole plate unit 1 and the back bonding fixed plate unit 3 and is used to push the end of the rectangular strip plate 401 outward.

[0065] In this embodiment, the cylinder 406 is the second implementation of the above-mentioned driving structure. Like the electromagnet 405, it can achieve the effective and flexible massage effect of the massage ball 202 by cooperating with the existing circuit on-off and size controller.

[0066] It does not matter whether the cylinder shaft of the cylinder 406 is connected to the exposed end of the rectangular strip 401 or not.

[0067] The long side direction of the rectangular strip 401 is horizontal.

[0068] Common sense tells us that it is more reasonable to divide the back area into upper, middle and lower, which correspond to the back, waist and sacrum respectively. The massage intensity and method required for the three are different.

[0069] Therefore, although the massage balls 202 can be extended in rows, the massage effect is average and not as good as extending them in rows, so the long side of the rectangular strip 401 is set to be horizontal, which is a better solution.

[0070] The massage ball 202 is provided with a thread groove for screwing the rod body 201 .

[0071] In this embodiment, a threaded section is provided on the outer end of the rod body 201, so that the massage ball 202, which is relatively easy to break, can be replaced separately, which is very convenient.

[0072] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
