Description

Technical Field

[0001] This utility model relates to the field of seat base technology, specifically to an electric base structure for a recliner. Background Technology

[0002] In the existing technology, a chair is a piece of furniture used to support the human body in a sitting posture and provide comfort and support. As people's living standards continue to improve, people's requirements for the comfort of chairs are also getting higher and higher.

[0003] In existing technology, chairs are usually composed of a support base, a seat board, and a backrest. A reclining chair is a chair in which the user can recline at a certain angle relative to the center line of the seat base when leaning against the backrest. Because it can relax the user after sitting for a long time and relieve muscle fatigue, and in order to meet the needs of people of different heights, the demand for it is increasing. In response to this demand, this utility model proposes an electric base structure for a reclining chair. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide an electric base structure for a reclining chair to solve the problems mentioned in the background art.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An electric base structure for a reclining chair includes: The chassis is mounted on the seat base, with a sway mechanism in the middle of the chassis and support plates at both ends of the chassis. A locking mechanism is mounted on the chassis via a mounting base on one side of the oscillating mechanism. The locking mechanism is used to control the operation of the oscillating mechanism. The locking mechanism includes a locking shaft, a locking assembly, and a driving assembly. The locking shaft is used to insert into the oscillating lock slot of the oscillating mechanism. The locking assembly includes a locking box for locking the locking shaft in the locking box so that it is away from the oscillating lock slot. The driving assembly is used to drive the locking shaft to reciprocate between a position where one end is in the locking box and a position where the other end is in the oscillating lock slot. The chair connecting mechanism has two components, which serve as adjustable structures for the seat base and are respectively arranged inside the support plate on the same side. A chair fixing mechanism is installed on a mounting base. One end of the chair fixing mechanism is connected to the locking shaft of the locking mechanism, and the other end cooperates with the chair connecting mechanism located on the same side of the locking mechanism. The chair fixing mechanism is used to assist in the coordinated control between seat base adjustment and swing. An electric telescopic mechanism is provided on the chassis on the side away from the locking mechanism of the sway mechanism. The electric telescopic mechanism is used to adjust the seat base.

[0006] Furthermore, the locking mechanism also includes a first fixing plate and a second fixing plate for supporting the locking shaft. The first fixing plate and the second fixing plate are vertically arranged parallel to each other on the mounting base. The first fixing plate and the second fixing plate are respectively provided with a first through hole and a second through hole for the locking shaft to pass through, so that the driving component drives the locking shaft to reciprocate in the relative direction of the first through hole and the second through hole.

[0007] Furthermore, the locking box is provided with an opening for the locking shaft to enter and exit, and the opening of the locking box is opposite to the groove of the lock slot. The center of the opening of the locking box is on the same horizontal straight line as the center of the first through hole, the second through hole, and the lock slot.

[0008] Furthermore, the drive assembly includes a drive plate fixedly connected to the locking shaft, the drive plate being connected to an external power cylinder, and the power cylinder driving the drive plate to reciprocate along the same moving direction as the locking shaft.

[0009] Furthermore, the drive assembly also includes a spring, which is disposed on the locking shaft between the drive plate and the second fixed plate.

[0010] Furthermore, the locking shaft is connected to a metal ball that can enter and exit the locking box at one end, and the locking box is equipped with an electromagnet that can attract the metal ball when energized.

[0011] Furthermore, the chair connecting mechanism includes a seat cushion support piece, which is installed on a support plate on the side away from the reclining mechanism. The seat cushion support piece is connected to the rear end of the back support piece, and the footrest support piece is connected to the bottom of the back support piece. The seat cushion support piece and the footrest support piece are connected together.

[0012] Furthermore, the chair fixing mechanism includes a fixing frame, a fixing shaft, and a connecting piece. The fixing shaft is slidably connected inside the fixing frame. One end of the fixing shaft is connected to the locking shaft through the connecting piece, and the other end cooperates with the back support piece.

[0013] Furthermore, the electric telescopic mechanism includes an electric cylinder, which is rotatably connected to the chassis. The telescopic end of the electric cylinder is rotatably connected to a connecting rod, which is positioned between two foot support plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are: (1) This utility model sets a drive assembly and a locking assembly on the chassis. Specifically, a power cylinder is set on the outside. The power cylinder drives the drive plate to move towards the locking box. At the same time, the force of the drive will compress the spring. The drive plate drives the locking shaft towards the locking box in the opposite direction of the first through hole and the second through hole. The metal ball at one end of the locking shaft enters the locking box through the opening of the locking box under the drive of the drive plate. When the electromagnet in the locking box is energized, it attracts the metal ball, so that the locking shaft moves away from the sway lock groove. At this time, there is no locking shaft in the sway lock groove to cooperate with it, so that the sway mechanism drives the seat to sway. Conversely, when the drive plate lacks the drive of the power cylinder and the electromagnet in the locking box is not energized, the end of the locking shaft away from the metal ball moves back into the sway lock groove under the action of the spring. At this time, there is a locking shaft in the sway lock groove to cooperate with it, so that the sway mechanism stops swaying the seat, thereby realizing the start and stop of the swaying of the seat.

[0015] (2) In this utility model, one end of the chair fixing mechanism is connected to the locking shaft, and the other end is engaged with the chair connecting mechanism. Specifically, the locking shaft is driven by the power cylinder to move towards the back support plate, so that one end of it enters the locking box, and the seat is in a swinging motion. At the same time, the driving force compresses the spring, and the connecting plate drives the fixing shaft to move towards the back support plate, so that the end of the fixing shaft will insert into the back support plate and engage with it, thereby fixing the position of the back support plate. Furthermore, through the interconnection between the seat support plate, the back support plate, and the footrest support plate, the seat support plate and the footrest support plate are also connected. The position of the support plate is fixed, making the seat base unadjustable. Conversely, when the locking component stops driving, the locking shaft loses the driving force of the drive component, and the spring returns, thereby driving the locking shaft to reset in the opposite direction of the back support plate. Then, the end of the locking shaft away from the back support plate will be inserted into the swaying mechanism, and the seat stops swaying. At this time, the fixed shaft and the fixed fit inside the back support plate will separate, allowing the user to adjust the seat base by adjusting the connection between the seat support plate, back support plate and footrest support plate through the electric cylinder, thereby achieving coordinated control between seat base adjustment and swaying.

[0025] like Figure 1 and Figure 2 As shown, this utility model embodiment provides an electric base structure for a reclining chair, including a chassis 1, a locking mechanism 2, two chair connecting mechanisms 3, a chair fixing mechanism 4, and an electric telescopic mechanism 5. The chassis 1 is mounted on the seat base, with a reclining mechanism 6 in the middle of the chassis 1 and support plates 7 at both ends of the chassis 1. The locking mechanism 2 is mounted on the chassis 1 via a mounting base 8, located on one side of the reclining mechanism 6. The locking mechanism 2 is used to control the operation of the reclining mechanism 6. The locking mechanism 2 includes a locking shaft 201, a locking component, and a driving component. The locking shaft 201 is used to insert into the reclining lock groove of the reclining mechanism 6 to stop the reclining of the chair. The locking component includes a locking box 202, used to lock the locking shaft 201 in the locking box 202 so that it is away from the reclining lock groove and the chair is able to move freely. The seat rocking mechanism is driven by a drive assembly that allows the locking shaft 201 to reciprocate between a position where one end is in the rocking lock groove and the other end is in the locking box 202, thus switching between rocking and rocking. Two chair connecting mechanisms 3, serving as adjustable structures for the seat base, are respectively located inside the support plate 7 on the same side. A chair fixing mechanism 4 is mounted on the mounting base 8, with one end connected to the locking shaft 201 of the locking mechanism 2 and the other end cooperating with the chair connecting mechanism 3 located on the same side of the locking mechanism 2. The chair fixing mechanism 4 assists in coordinating control between seat base adjustment and rocking. An electric telescopic mechanism 5 is located on the chassis 1 on the side of the rocking mechanism 6 away from the locking mechanism 2, and is used to adjust the seat base.

[0026] In this embodiment, the locking mechanism 2 further includes a first fixing plate 204 and a second fixing plate 205 for supporting the locking shaft 201. The first fixing plate 204 and the second fixing plate 205 are vertically arranged parallel to each other on the mounting base 8. The first fixing plate 204 and the second fixing plate 205 are respectively provided with a first through hole 207 and a second through hole 208 for the locking shaft 201 to pass through, so that the driving component drives the locking shaft 201 to reciprocate in the relative direction of the first through hole 207 and the second through hole 208, so that the driving component can drive the locking shaft 201 to reciprocate in the relative direction of the first through hole 207 and the second through hole 208.

[0027] In this embodiment, the drive assembly includes a drive plate 206 fixedly connected to the locking shaft 201. The drive plate 206 is connected to an external power cylinder, and the power cylinder drives the drive plate 206 to reciprocate along the same moving direction as the locking shaft 201.

[0028] In this embodiment, the drive assembly also includes a spring, which is disposed on the locking shaft 201 between the drive plate 206 and the second fixing plate 205.

[0029] Specifically, when the power cylinder is started, the power cylinder drives the drive plate 206 to move back and forth. The drive plate 206 drives the locking shaft 201 to move back and forth in the opposite direction of the first through hole 207 and the second through hole 208. Under the constraint of the spring, the drive plate 206 moves within a certain range, so that the locking shaft 201 also moves within a certain range. When the power cylinder is stopped, the drive plate 206 returns to the position before starting.

[0030] In this embodiment, the locking box 202 is provided with an opening 203 for the locking shaft 201 to enter and exit, and the opening 203 of the locking box 202 is arranged opposite to the slot of the lock groove. The center of the opening 203 of the locking box 202 is on the same horizontal straight line as the center of the first through hole 207, the second through hole 208 and the lock groove.

[0031] Specifically, the drive assembly drives the locking shaft 201 to pass through the opening 203 of the locking box 202 and enter the locking box 202 to be locked. At this time, there is no locking shaft 201 in the swing lock groove to cooperate with it, so that the swing mechanism 6 drives the swing of the seat.

[0032] In this embodiment, a metal ball 209 that can enter and exit the locking box 202 is connected to one end of the locking shaft 201 near the locking box 202. The locking box 202 is equipped with an electromagnet that can attract the metal ball 209 when energized.

[0033] Specifically, when the drive plate 206 drives the locking shaft 201 with the metal ball 209 connected to it into the locking box 202, the electromagnet in the locking box 202 is energized. The energized electromagnet generates magnetism and attracts the metal ball 209, thereby fixing the locking shaft 201 with the metal ball 209 connected to it in the locking box 202. The locking shaft 201 is located away from the swing lock slot. At this time, there is no locking shaft 201 in the swing lock slot to cooperate with it, so that the swing mechanism 6 drives the swing of the seat.

[0034] In this embodiment, the chair connecting mechanism 3 includes a seat cushion support plate 301, which is installed on a support plate 7 on the side away from the relaxation mechanism 6. The seat cushion support plate 301 is connected to the rear end of the back support plate 302, and the footrest support plate 303 is connected to the bottom of the back support plate 302. The seat cushion support plate 301 and the footrest support plate 303 are connected to each other, so that the seat base is adjustable.

[0035] In this embodiment, the chair fixing mechanism 4 includes a fixing frame 401, a fixing shaft 402 and a connecting piece 403. The fixing shaft 402 is slidably connected in the fixing frame 401. One end of the fixing shaft 402 is connected to the locking shaft 201 through the connecting piece 403, and the other end cooperates with the back support piece 302.

[0036] Specifically, when the locking shaft 201 is driven by the drive plate 206, it drives the linkage plate 403 to move. The movement of the linkage plate 403 drives the fixed shaft 402 to move. The fixed shaft 402 moves towards the back support plate 302, so that the end of the fixed shaft 402 inserts into the back support plate 302 and cooperates with it, thus fixing the position of the back support plate 302. Through the interconnection between the seat support plate 301, the back support plate 302, and the footrest support plate 303, the positions of the seat support plate 301 and the footrest support plate 303 are also fixed, making the seat base non-adjustable. Conversely, when the fixed shaft 402 moves away from the back support plate 302, the end of the fixed shaft 402 moves away from the back support plate 302, and the back support plate 302 is not fixed, nor are the seat support plate 301 and the footrest support plate 303, making the seat base adjustable.

[0037] In this embodiment, the electric telescopic mechanism 5 includes an electric cylinder 501, which is rotatably connected to the chassis 1. The telescopic end of the electric cylinder 501 is rotatably connected to the connecting rod 502, which is disposed between the two foot support plates 303.

[0038] Specifically, when the back support plate 302, seat support plate 301, and footrest support plate 303 are not fixed, the electric cylinder 501 drives the connecting rod 502 to move, and the movement of the connecting rod 502 causes the footrest support plate 303 to move, thereby realizing the adjustment of the seat base.

[0039] The working principle of this embodiment is as follows: During use, the power cylinder is activated, driving the drive plate 206 to move towards the locking box 202. Simultaneously, the driving force compresses the spring, causing the drive plate 206 to move the locking shaft 201 towards the locking box 202 in the opposite direction of the first through hole 207 and the second through hole 208. When the metal ball at one end of the locking shaft 201 penetrates the opening 203 of the locking box 202 and enters the locking box 202 under the drive of the drive plate 206, it energizes the electromagnet inside the locking box 202. The energized electromagnet generates magnetism, attracting the metal ball 209, thus fixing the end of the locking shaft 201 connected to the metal ball 209 to the locking box. Within 202, the locking shaft 201 is moved away from the sway lock groove. At this time, there is no locking shaft 201 in the sway lock groove, which causes the sway mechanism 6 to drive the seat to sway. At the same time, the locking shaft 201 also drives the fixed shaft 402 to move towards the back support plate 302 through the linkage plate 403, so that the end of the fixed shaft 402 will insert into the back support plate 302 and cooperate with it, so that the position of the back support plate 302 is fixed. Furthermore, through the interconnection between the seat support plate 301, the back support plate 302, and the footrest support plate 303, the positions of the seat support plate 301 and the footrest support plate 303 are also fixed, making the seat base unadjustable. When the drive plate 206 lacks the power cylinder drive and the electromagnet in the locking box 202 is not energized, the end of the locking shaft 201 away from the locking box 202 moves back into the relaxation lock groove under the action of the spring. At this time, there is a locking shaft 201 in the relaxation lock groove that cooperates with it, so that the relaxation mechanism 6 stops the relaxation of the seat. At the same time, the locking shaft 201 drives the fixed shaft 402 to move in the opposite direction of the back support plate 302 through the linkage plate 403. The fixed engagement between the fixed shaft 402 and the back support plate 302 will be separated, so that the user can adjust the seat base by adjusting the connection relationship between the seat support plate 301, the back support plate 302 and the footrest support plate 303 through the electric cylinder 501.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
