[0096] The swing mechanism of the electric sofa drives the iron frame to swing back and forth, but the swing mechanism is often specially designed according to the structure of the carried iron frame, and the swing mechanism does not have universality and cannot carry various iron frame structures. Even if it can be compatible with multiple iron frames, due to the structural limitation of the swing mechanism, the coordination between the swing amplitude and the up-and-down fluctuation distance is poor during the swing process, and it is difficult to achieve the requirement of smooth swing.
[0097] Therefore, the current technical problem is how to design a swing mechanism that can not only adapt to different types of sofa iron frames but also effectively coordinate the relationship between the front and rear swing amplitudes and the up-and-down fluctuation during the swing process, so as to achieve a smooth swing effect.
[0098] The embodiment constructs an approximately inverted trapezoidal structure composed of a suspension point A, a suspension point B, a hinge position C and a hinge position D to limit the front and rear swing distance and the up-and-down fluctuation distance. When the swing mechanism is installed with the iron frame, the bottom support positions of the left and right pieces of the iron frame, such as the support ends, can correspond to the iron frame connection positions on the carrier, thereby improving the installation compatibility of the iron frame. Even if different types of iron frames are installed, consistent swing effects can be achieved.
[0099] It should be noted that: similar reference numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. In addition, in the drawings, the thickness of the components can be exaggerated or reduced for effective description of the technical content.
[0100] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.
[0101] As shown in Figures 1 to 3 In order to better show the assembly relationship of the swing mechanism and the sofa iron frame, the specific assembly structure can be referred to Figure 2 andFigure 3 As shown. Specifically, in order to provide at least one implementation of a swing mechanism to solve the above problems, such as Figure 1 As shown, Figure 1 This is a schematic diagram of the swing mechanism provided in an embodiment of the present disclosure. The swing mechanism may include: a base 100, a swing support frame 200, a left support plate 210a, a right support plate 210b, suspension point A, suspension point B, and two iron frame support frames 300 respectively corresponding to the left support plate 210a and the right support plate 210b. Each iron frame support frame 300 includes a first rocker arm 310a, a second rocker arm 310b, a support member 320, a hinge position C, and a hinge position D. For a better representation of the assembly relationship between the swing mechanism and the sofa frame, see [reference needed]. Figure 2 and Figure 3 Arrow F1 indicates the leg direction, and arrow F2 indicates the back direction. The first iron frame connection position 321 and the second iron frame connection position 322 respectively support the left iron frame piece 400a and the right iron frame piece 400b. The left iron frame piece 400a and the right iron frame piece 400b are symmetrically mounted on the support member 320 to form the overall iron frame structure of the sofa. Figure 1 It can be seen that the swing support frame 200 is located on the base 100 and includes a left support plate 210a and a right support plate 210b. Both the upper ends of the left support plate 210a and the right support plate 210b are provided with suspension points A and B. Two iron frame carriers 300 are respectively located on the outer sides of the left support plate 210a and the right support plate 210b, and each includes a first rocker arm 310a and a second rocker arm 310b. The upper ends of the first rocker arm 310a and the second rocker arm 310b are hinged to the suspension points A and B of the corresponding support plates, respectively, and the lower ends of the first rocker arm 310a and the second rocker arm 310b are hinged to the hinge positions C and D of the carrier 320, respectively. Figure 3 It can be seen that at least one first iron frame connection position 321 is provided on the bearing member 320 and on the side of the hinge position C facing away from the iron frame leg, and at least one second iron frame connection position 322 is provided on the side of the hinge position D facing the back of the iron frame.
[0102] In some embodiments, during actual use, since the bearing member 320 has a long reserved space on the hinge position C facing away from the iron frame leg and on the hinge position D facing the back of the iron frame, different models of iron frame left piece 400a and iron frame right piece 400b can be installed as needed to form a complete sofa iron frame structure.
[0103] Combination Figure 1, the hanging point A, the hanging point B, the hinge position C and the hinge position D form an approximate inverted trapezoid, the carrier 320 is located at the lower part of the inverted trapezoid, and the two carriers 320 respectively carry the left piece 400a and the right piece 400b of the iron stand. In some embodiments, in order to meet the swing stability caused by the deformation of the above-mentioned inverted trapezoidal structure during the swing, the structure of the inverted trapezoid and the swing process are limited by the corresponding parameters as follows:
[0104] Figure 4 is a schematic view of the swing mechanism swinging in the F1 direction, Figure 6 is a schematic view of the swing mechanism swinging in the F1 direction and the F2 direction, wherein the F1 direction is represented by a solid line, the F2 direction is represented by a dashed line, and the swing angle of the first rocker arm 310a is represented by β.
[0105] As shown in Figure 4 and Figure 6 , the swing angle β of the first rocker arm 310a is limited to 10°-55°, preferably 25-50°, and specifically can be 28°, 34°, 45° or 48°. The straight-line distance between the hanging point A and the hanging point B is L1, the straight-line distance between the hinge position C and the hinge position D is L2, and L1:L2=(12-13):(10-12). The above values are proportional values, which can be adjusted according to the actual situation according to the above proportions. Specifically, in order to meet the above constraints, L1 can be limited to 240mm-260mm, and L2 can be limited to 200mm-240mm. By limiting the up-down distance and the swing angle β of the first rocker arm 310a, the overall swing deformation of the inverted trapezoidal structure can be better controlled, and a more stable swing state can be obtained.
[0106] In combination with Figure 4 and Figure 5 , when the carrier 320 swings, the first rocker arm 310a swings to the side of the iron stand leg (see arrow direction F1), and when the first rocker arm 310a swings to the maximum amplitude to the side of the leg, the maximum angle between the line connecting the hinge position C and the hinge position D and the horizontal plane is α1, wherein Figure 4 α1 above the horizontal line can be defined as a positive value, Figure 5 α1 below the horizontal line can be defined as a negative value; in combination with Figure 6 and Figure 7 , the first rocker arm 310a swings to the side of the iron stand backrest (see arrow direction F2), the hinge position C and the hinge position D move, and the action relationship continues from Figure 6 to Figure 7, when the first rocker arm 310a swings to the maximum amplitude toward the backrest side, the maximum angle between the line connecting the hinged position C' and the hinged position D' and the horizontal line is a2, and the a2 angle is above the horizontal line and is defined as a positive value; wherein a1: a2: L2 = (1° ~ 4°): (2° ~ 6°): (200mm ~ 240mm); from Figure 7 It can be seen that the opening directions of a1 and a2 are opposite. a1 and a2 can be converted into the pitch angle of the human sitting posture in the swinging process. Through the above parameter limitation, when a person sits, a better pitch angle is obtained, and the comfort of one or more posture adjustments such as a sofa iron frame sitting posture, a TV position, and a lying posture can be at least met.
[0107] Please refer to Figure 6 , the straight-line distance between the hanging point A and the hanging point B is L1, the straight-line distance between the hinged position C and the hinged position D is L2, and L1: L2 = (240 ~ 260): (200 ~ 240); and Figure 3 and Figure 4 , the height difference H1 between the highest position and the lowest position of the hinged position C when the carrier swings; wherein L1: L2: H1 = (240 ~ 260): (200 ~ 240): (2 ~ 25). Through the above parameter limitation, when a person sits, the height of the ups and downs in the swinging process is controlled, so that the person obtains a more smooth swinging experience, and the comfort of one or more posture adjustments such as a sofa iron frame sitting posture, a TV position, and a lying posture can be at least met.
[0108] Please continue to refer to Figure 6 , the straight-line distance between the hanging point A and the hanging point B is L1, the straight-line distance between the hinged position C and the hinged position D is L2, and L1: L2 = (240 ~ 260): (200 ~ 240); and the front and back swinging value L when the carrier swings. The front and back swinging value L is specifically the horizontal distance between the hinged position C when the first rocker arm 310a swings to the maximum amplitude toward the leg side and the hinged position C' when the first rocker arm 310a swings to the maximum amplitude toward the backrest side. Wherein, L1: L2: L = (240 ~ 260): (200 ~ 240): (8 ~ 85). The front and back swinging value L corresponds to the front and back distance of the iron frame in the swinging process. In some embodiments, by limiting the distance of L1 and / or L2 and / or L, the front and back swinging amplitude can be limited, so that the person obtains a more smooth swinging experience, and the comfort of one or more posture adjustments such as a sofa iron frame sitting posture, a TV position, and a lying posture can be at least met. For example, moving the C point forward can shorten the length of L2, that is, the swinging amplitude of L can be adjusted at the same time, the swinging amplitude is reduced, and the swinging is more smooth.
[0109] Please refer to Figure 8, the straight-line distance between the suspension point A and the suspension point B is L1, the straight-line distance between the hinging position C and the hinging position D is L2; and the suspension point A and the suspension point B are approximately level, and when the bearing member is in a natural suspension state, due to the approximate horizontal state of the suspension point A and the suspension point B, a CD connecting line is constructed between the hinging position C and the hinging position D, and the vertical distance between the suspension point A and the CD connecting line is H; wherein L1:L2:H=(240~260):(200~240):(83~120). The above H value determines the height of the bearing member, and also limits the ground clearance during the swing of the iron stand in actual application; for example, in the natural drooping state of the bearing member 320, the vertical distance H can be 90mm, 112mm or 120mm, and as the bearing member 320 swings, the vertical distance H changes, and in order to meet the height of the sofa body and the ground, and to ensure the height of the seat, the value of H in the natural drooping state of the bearing member 320 is particularly important.
[0110] Please refer to Figure 1 and Figure 9 , in some embodiments, the swing mechanism can include a driving mechanism 500, and the driving end of the driving mechanism 500 is hinged with the two iron stand bearing frames to drive the bearing member to swing. For example, the first rocker arm 310a can be used as a power arm through the driving cross arm 330, and the second rocker arm 310b can be used as a driven arm, of course, in some embodiments, the second rocker arm 310b can also be used as a power arm, and the driving cross arm 330 can be used as a driven arm.
[0111] Please refer to Figure 1 , as an optional connection mode of the driving mechanism, the driving cross arm 330 is arranged between the first rocker arm 310a of the two iron stand bearing frames 300, and the driving cross arm 330 is hinged with the driving end.
[0112] Figure 1 is a structural schematic diagram of the driving motor 520, the crank arm 530 and the eccentric wheel 540 as an embodiment, of course, other embodiments can also be used to realize, Figure 1 is only an embodiment schematic diagram of the driving mode, and does not limit the swing mechanism to adopt the above specific embodiments of the driving motor 520, the crank arm 530 and the eccentric wheel 540.
[0113] As shown in Figure 9 , for example, the linear driver 501, the extension end of the linear driver 501 is used as the driving end, and the extension end of the linear driver 501 is also hinged with the driving cross arm 330; the extension distance of the linear driver 501 makes the swing angle of the first rocker arm 310a be 10°~55°. The extension mode of the linear driver 501 is shown by an arrow F3 in Figure 9 , and the first rocker arm swings as shown by an arrow F4.
[0114] Please refer to Figure 1 and Figure 10 , the eccentricity of the eccentric wheel 540 is positively correlated with the swing amplitude of the swing frame. By limiting the eccentricity of the eccentric wheel 540, the specific parameter limit of the eccentricity is shown in the following table, thereby adjusting the swing amplitude of the bearing 320 to meet the installation and swing requirements of different types of electric sofa iron frames. Specifically, the suspension points A and B, the hinge positions C and D form an approximately inverted trapezoid, which makes the bearing 320 carrying the sofa iron frame swing in an elliptical trajectory under the drive of the curved arm 530. For details, see Figures 3 to 7 .
[0115] Please refer to Figure 6 and Figure 10 , the eccentricity a of the eccentric wheel 540 is the distance between the axis O of the rotating bearing 550 and the axis O' of the drive motor output shaft 521, and the rotating bearing 550 can be arranged in a concentric manner inside the eccentric wheel 540; when the bearing swings, the height difference H1 between the highest point and the lowest point of the hinge position C in the bearing; wherein a: H1 = 1: (1~2).
[0116] Please refer to Figure 6 and Figure 10 , in some embodiments, the eccentricity a; when the bearing swings, the front and back swing value of the hinge position C is L; wherein a: L = 1: (3~5).
[0117] For example, under different eccentricity conditions, the corresponding H1 and L values are shown in the following table:
[0118] Eccentricity a (mm) H1 (mm) H2 (mm) H3 (mm) L (mm) L3 (mm) L4 (mm) 2.5 2.52 113.72 111.2 9.9 23.65 33.55 5 5.04 114.64 109.6 19.8 18.67 38.47 7.5 7.6 115.35 107.75 29.7 13.67 43.37 10 10.18 115.83 105.65 39.62 8.65 48.27 12.5 12.82 116.1 103.28 49.56 3.6 53.16 15 15.53 116.14 100.61 59.52 (-1.47) 58.05 17.5 18.36 115.97 97.61 69.51 (-6.56) 62.95 20 21.32 115.57 94.25 79.55 (-11.67) 67.88
[0119] In the above table, H2 is Figure 6 the height difference between point C and point A when point C moves to the lowest point, H3 is Figure 6 the height difference between point C' and point A when point C moves to the highest point. The height difference H1 = H2-H3.
[0120] L3 is Figure 6 the horizontal movement distance of the hinge position C relative to the vertical line of the suspension point A when it moves to the limit of the leg side F1, and L4 is the horizontal movement distance of the hinge position C relative to the vertical line of the suspension point A when it moves to the limit of the back side F2. In the table, the hinge point is set to the right side of the vertical line of the suspension point A as positive, such as the value 23.65~3.6 in the table L3, and the hinge point is set to the left side of the vertical line of the suspension point A as negative, such as -1.47~-11.67, and the specific values are shown in the following table: Figure 6Taking the case that the hinge point is located on the left side of the vertical line of the hanging point A, the distance between L3 and L4 is defined as the swing value L = |L4-L3|.
[0121] From the above table, it can be seen that the corresponding relationship of the height difference H1 with respect to the eccentric shaft a is between (a, 2a). The corresponding relationship of the swing value L with respect to the eccentric shaft a is between (3a, 5a).
[0122] Please refer to Figures 1 to 4 , at least one embodiment also provides a swing mechanism, which can further include a base; a swing support frame 200 located on the base and including a left support piece 210a and a right support piece 210b, the upper ends of the left support piece 210a and the right support piece 210b are symmetrically provided with a hanging point A and a hanging point B, respectively; two iron stand bearing frames 300, each including a first rocker arm 310a and a second rocker arm 310b; wherein the upper ends of the first rocker arm 310a and the second rocker arm 310b are respectively hinged to the hanging point A and the hanging point B of the corresponding support piece, and the lower ends of the first rocker arm 310a and the second rocker arm 310b are respectively hinged to the hinge points C and D of the bearing 320; wherein the swing angle of the first rocker arm 310a is 10°-55°; and the straight line distance between the hanging point A and the hanging point B is L1, the straight line distance between the hinge points C and D is L2, and L1:L2=(240mm-260mm):(200mm-240mm). In this embodiment, the bearing 320 can be realized by a connecting rod at the bottom of the iron stand left piece 400a and the iron stand right piece 400b. Figure 11 In this embodiment, the bearing 320 belongs to the iron stand. Figure 11 As a structural schematic diagram of another embodiment of the swing mechanism provided by the present disclosure, the bearing 320 can also be a part of the bottom of the sofa iron stand. Therefore, in some embodiments, whether the bearing 320 in the above-mentioned swing mechanism belongs to a part of the sofa iron stand does not hinder the specific implementation of the swing mechanism.
[0123] Please refer to Figures 1 to 4 , at least one embodiment also provides a swing mechanism, which can further include a left support piece 210a and a right support piece 210b, the upper ends of which are provided with a hanging point A and a hanging point B; a first rocker arm 310a and a second rocker arm 310b corresponding to the support piece, the upper ends of which are respectively hinged to the hanging point A and the hanging point B so that the lower ends are respectively hinged to the hinge points C and D of the bearing 320; wherein the straight line distance between the hanging point A and the hanging point B is L1, the straight line distance between the hinge points C and D is L2, and L1:L2=(240mm-260mm):(200mm-240mm); and a driving mechanism 500 for driving the first and second rocker arms to swing synchronously, wherein the swing angle of the first rocker arm is 10°-55°. In this embodiment, the bearing 320 can be realized by a connecting rod at the bottom of the iron stand left piece 400a and the iron stand right piece 400b.Figure 11 The linkage with the bottom of the left iron frame piece 400a and the right iron frame piece 400b can be achieved by the bearing member 320, and the embodiment does not limit the ownership of the bearing member 320.
[0124] The related parameter constraints of the approximate inverted trapezoidal structure formed by the hanging point A, the hanging point B, the hinge position C, and the hinge position D are described in detail in the above embodiment, and will not be repeated here.
[0125] In some embodiments, the specific implementation of the driving mechanism 500 is described in detail above.
[0126] Please refer to Figure 2 and Figure 3 At least one embodiment also provides an electric rocking chair, comprising a swinging mechanism; and a sofa iron frame arranged on the bearing member 320 and comprising left and right pieces (such as the left iron frame piece 400a and the right iron frame piece 400b), and the support ends of the left and right iron frame pieces are arranged on the corresponding bearing member respectively.
[0127] In some embodiments, at least two support ends of the left and right iron frame pieces are connected with the first iron frame connection position arranged on the hinge position C away from the iron frame leg side and the second iron frame connection position arranged on the hinge position D towards the iron frame back side respectively.
[0128] Please refer to Figure 11 The bearing member 320 can also be part of the bottom of the sofa iron frame. Therefore, as shown in Figures 1 to 10 , the bearing member 320 can be independently arranged, or can be considered as a whole part of the sofa iron frame. Figure 11
[0129] Since the bearing member can be independently arranged or belong to part of the sofa iron frame, the specific iron frame connection position can be adjusted according to the actual situation, as long as the hanging point A, the hanging point B, the hinge position C, and the hinge position D form an approximate inverted trapezoid, and the bearing member 320 is located at the lower part of the inverted trapezoid, that is, the corresponding technical effect of the swinging mechanism can be achieved.
[0130] In summary, the swinging mechanism and the electric rocking chair construct an approximate inverted trapezoidal structure by the hanging point A, the hanging point B, the hinge position C, and the hinge position D to limit the front and rear swinging distance and the up and down fluctuation distance. When the iron frame is installed in the swinging mechanism, the support position of the bottom of the left and right pieces of the iron frame can correspond to the iron frame connection position located on the bearing member, thereby improving the installation compatibility of the iron frame and meeting the same swinging effect after installing different iron frames.
