Description

Technical Field

[0001] This utility model relates to the field of mechanical processing equipment, specifically to a novel chassis structure for a reclining chair. 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 refers to a chair in which the user can "recline" and rock 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, its demand is increasing day by day. In response to this demand, this utility model proposes a new chassis 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 a novel chassis 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: A novel chassis structure for a reclining chair includes a chassis on which a locking mechanism is mounted via a first mounting seat. The locking mechanism includes a locking shaft for inserting into a reclining lock slot, a locking component for locking the locking shaft within a locking box and away from the reclining lock slot, and a driving component for driving the locking shaft to reciprocate between a position at one end within the reclining lock slot and a position at the other end within the locking box. The chassis is provided with a first fixing plate and a second fixing plate that are parallel to each other for supporting the locking shaft. The first fixing plate and the second fixing plate are respectively provided with a first through hole and a second through hole through which the locking shaft passes, such that the driving component drives the locking shaft to reciprocate in the opposite direction of the first through hole and the second through hole. The opening on the locking box for the locking shaft to enter and exit is positioned opposite to the opening of the reclining lock slot, and the center of the opening of the locking box is on the same horizontal line as the center of the first through hole, the second through hole, and the reclining lock slot.

[0006] Furthermore, the chassis structure also includes a manual unlocking component, which includes a fixing frame, a drive shaft, and a connecting piece. The drive shaft is slidably connected within the fixing frame, with one end of the drive shaft connected to a locking shaft via the connecting piece, and the other end connected to a button located on the outside of the seat.

[0007] 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.

[0008] Furthermore, the drive assembly also includes a spring, which is disposed on the locking shaft between the drive plate and the second fixed plate.

[0009] Furthermore, the locking shaft is connected to a metal ball that can move in and out of the locking box at one end, and the locking box is equipped with an electromagnet that can attract the metal ball when energized.

[0010] Furthermore, a second mounting seat is installed in the middle of the chassis, and mounting plates are provided on both sides of the chassis, with the chassis mounted on the seat via the mounting plates.

[0011] Furthermore, a seat back adjustment connecting shaft is provided in the middle of the chassis on one side of the second mounting seat.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model sets a drive component and a locking component on the chassis. Specifically, a power cylinder is set externally. The power cylinder drives the drive plate to move back and forth. The drive plate drives the locking shaft to move back and forth in the opposite direction of the first through hole and the second through hole. Since the center of the opening of the locking box is on the same horizontal line as the center of the first through hole, the second through hole, and the center of the rocking mechanism's rocking lock groove, 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, causing the locking shaft to move away from the rocking lock groove. At this time, there is no locking shaft in the rocking lock groove to cooperate with it, so that the rocking mechanism drives the rocking chair to "rock". Conversely, the end of the locking shaft away from the metal ball moves back into the rocking lock groove under the drive of the drive plate. At this time, there is a locking shaft in the rocking lock groove to cooperate with it, so that the rocking mechanism stops the rocking chair from "rocking". Thus, the starting and stopping of the rocking chair's "rocking" is realized. Attached Figure Description

[0021] like Figure 1 and Figure 2As shown, this utility model embodiment provides a novel chassis structure for a reclining chair, including a chassis 1. A locking mechanism is mounted on the chassis 1 via a first mounting seat 10. The locking mechanism includes a locking shaft 2 for inserting into a reclining lock slot of the reclining mechanism, a locking component 3 for locking the locking shaft 2 within a locking box 301 and away from the reclining lock slot, and a driving component 4 for driving the locking shaft 2 to reciprocate between a position where one end is in the reclining lock slot and the other end is in the locking box 301. The chassis 1 is provided with a first fixing plate 6 and a second fixing plate 7 that are parallel to each other for supporting the locking shaft 2. The first fixing plate 6 and the second fixing plate 7 are respectively provided with a first through hole 8 and a second through hole 9 through which the locking shaft 2 passes, so that the driving component 4 drives the locking mechanism. Shaft 2 reciprocates in the opposite direction of the first through hole 8 and the second through hole 9. The opening 302 on the locking box 301 for the locking shaft 2 to enter and exit is set opposite to the slot of the rocker arm lock groove. The center of the opening 302 of the locking box 301 is on the same horizontal straight line as the center of the first through hole 8, the second through hole 9, and the center of the rocker arm lock groove. The drive assembly 4 drives one end of the locking shaft 2 to pass through the opening 302 of the locking box 301 and enter the locking box 301 and be locked. At this time, there is no locking shaft 2 in the rocker arm lock groove, so that the rocker arm mechanism drives the rocker arm chair to "rock". Conversely, the drive assembly 4 drives the other end of the locking shaft 2 to enter the rocker arm lock groove. At this time, there is a locking shaft 2 in the rocker arm lock groove, so that the rocker arm mechanism stops the rocker arm chair from "rocking".

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, the chassis 1 structure also includes a manual unlocking component 5. The manual unlocking component 5 includes a fixing frame 501, a drive shaft 502, and a connecting piece 503. The drive shaft 502 is slidably connected in the fixing frame 501, and the drive shaft 502 and the locking shaft 2 are set in the same direction. One end of the drive shaft 502 is connected to the side of the locking shaft 2 near the locking box 301 through the connecting piece 503, and the other end is connected to the button located on the outside of the seat.

[0023] Specifically, the user manually presses the button, causing the drive shaft 502 to move on the fixed frame 501 toward the direction of the rocking mechanism. The movement of the drive shaft 502 drives the locking shaft 2 to move toward the direction of the rocking mechanism through the connecting piece 503, so that the locking shaft 2 enters the rocking lock groove. At this time, there is a locking shaft 2 in the rocking lock groove, so that the rocking mechanism can immediately stop the rocking of the rocking chair.

[0024] In this embodiment, as Figure 1 and Figure 2 As shown, the drive assembly 4 includes a drive plate 401 fixedly connected to the locking shaft 2. The drive plate 401 is connected to an external power cylinder, which drives the drive plate 401 to reciprocate along the same moving direction as the locking shaft 2.

[0025] In this embodiment, the drive assembly 4 also includes a spring, which is disposed on the locking shaft 2 between the drive plate 401 and the second fixed plate 7.

[0026] Specifically, when the power cylinder is started, the power cylinder drives the drive plate 401 to move back and forth. The drive plate 401 drives the locking shaft 2 to move back and forth in the opposite direction of the first through hole 8 and the second through hole 9. Under the constraint of the spring, the drive plate 401 moves within a certain range, so that the locking shaft 2 also moves within a certain range. When the power cylinder is stopped, the drive plate 401 returns to the position before starting.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the locking shaft 2 is connected to a metal ball 201 that can enter and exit the locking box 301 at one end. The locking box 301 is equipped with an electromagnet that can attract the metal ball 201 when energized.

[0028] Specifically, when the drive plate 401 drives the locking shaft 2, with the metal ball 201 connected to it, into the locking box 301, the electromagnet in the locking box 301 is energized. The energized electromagnet generates magnetism, attracting the metal ball 201, thereby fixing the locking shaft 2 with the metal ball 201 connected to it in the locking box 301. The locking shaft 2 is located away from the rocker arm lock slot. At this time, there is no locking shaft 2 in the rocker arm lock slot to cooperate with it, so that the rocker arm mechanism drives the rocker arm chair to rock back and forth.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, a second mounting base 11 for mounting the sway mechanism is installed in the middle of the chassis 1, and mounting plates 12 are provided on both sides of the chassis 1, and the chassis 1 is mounted on the seat through the mounting plates 12.

[0030] In this embodiment, as Figure 1 and Figure 2 As shown, a seat back adjustment connecting shaft 13 is provided in the middle of the chassis 1 on one side of the second mounting seat 11. The back of the recliner can be adjusted by rotating the seat back adjustment connecting shaft 13 to meet the seating habits of different users.

[0031] The working principle of this embodiment is as follows: During use, the power cylinder is activated, driving the drive plate 401 to reciprocate. The drive plate 401 drives the locking shaft 2 to reciprocate in the opposite direction of the first through hole 8 and the second through hole 9. Since the center of the opening 302 of the locking box 301 is on the same horizontal line as the center of the first through hole 8, the second through hole 9, and the center of the remote lock groove, when the metal ball at one end of the locking shaft 2 penetrates the opening 302 of the locking box 301 and enters the locking box 301 under the drive of the drive plate 401, it energizes the electromagnet inside the locking box 301. The energized electromagnet generates magnetism, attracting the metal ball 201, thus fixing the end of the locking shaft 2 connected to the metal ball 201 inside the locking box 301, causing the locking shaft 2 to move away from the remote lock groove. At this time, the remote lock... When there is no matching locking shaft 2 in the slot, the reclining mechanism drives the reclining chair to "recline". Conversely, when the end of the locking shaft 2 away from the metal ball is driven by the drive plate 401, it moves back into the reclining lock slot. At this time, there is a matching locking shaft 2 in the reclining lock slot, which stops the reclining mechanism from "reclining" the reclining chair. When it is necessary to stop the reclining of the reclining chair immediately, the user can manually press the button to move the drive shaft 502 on the fixed frame 501 toward the reclining mechanism. The movement of the drive shaft 502 drives the locking shaft 2 toward the reclining mechanism through the connecting piece 503, so that the locking shaft 2 enters the reclining lock slot. At this time, there is a matching locking shaft 2 in the reclining lock slot, which allows the reclining mechanism to immediately stop the reclining of the reclining chair.

[0032] 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.
