Description

Technical Field

[0001] This utility model relates to the field of electric seat technology, and in particular to a coordinated adjustment mechanism and an electric seat. Background Technology

[0002] Electric chairs are a common type of furniture, allowing people to adjust their posture as needed. Electric chairs typically offer three sitting positions: reclining, TV position, and sitting. Each electric chair consists of a leg rest, seat, and backrest. In the sitting position, the legs are closed, the seat is horizontal, and the backrest is nearly upright. In the TV position, also known as the television posture, the legs are extended forward, and the backrest remains largely unchanged. In the reclining position, the backrest is tilted back, and the legs remain largely unchanged for rest.

[0003] In the existing technology, electric seats achieve different positions through corresponding adjustment mechanisms. However, these adjustment mechanisms are relatively complex and require multiple drive units to achieve adjustment and support, resulting in high manufacturing costs. Utility Model Content

[0021] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention. It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0022] In the description of this application, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this utility model.

[0023] In this application, unless otherwise expressly specified and limited, the terms "connection," "setup," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0025] Example 1: like Figures 1-2 As shown in the figure, this application discloses a collaborative adjustment mechanism and an electric seat, which are used to realize the rotation of the electric seat and the zero-gravity experience. Specifically, the collaborative adjustment mechanism is designed to simplify its structure while ensuring initial stability.

[0026] like Figure 1 As shown, the coordination mechanism in this application includes: The base frame 1 serves as a support component, providing support and protecting the stability of the seat when other components are subsequently installed. The connecting frame 2 is installed on the base frame 1 at one end. The connecting frame 2 is used to ensure the stability of the subsequent support frame 3. The subsequent support frame, as the main load-bearing component, needs to be supported by the connecting frame 2 to ensure stability. Support frame 3 is installed at the other end of the connecting frame 2. The support frame 3 is used to place a seat or other fittings to facilitate sitting or lying down for the user. Linkage mechanism 4 is movably installed at the end of the support frame 3. This linkage mechanism 4 can be an existing mechanism or a newly designed structure, which makes it easy for users to switch between sitting and lying positions. The drive unit 5 is mounted on the base frame 1 at one end and connected to the support frame 3 at the other end. When the drive unit 5 pushes the support frame 3 to rotate, it drives the linkage mechanism 4 to extend or retract. That is, the drive unit in this application is a power component used to provide power. Preferably, the drive unit 5 is an electric push rod used to provide power, which simplifies the structure.

[0027] Compared to existing adjustment mechanisms, the adjustment mechanism in this application is simpler. To ensure overall stability, the connecting frame 2 is designed to improve support stability. Specifically, the connecting frame in this application includes: At least two diagonal braces 201 are installed at intervals on the base frame 1; The positioning plate 202 is connected to the bottom of all the diagonal braces 201. The positioning plate 202 is used to ensure the stability of the diagonal brace connection, that is, to ensure the stability of the two diagonal braces 201. At the same time, they are connected to the same positioning plate 202, which can ensure consistency and better ensure the stability of their top support frame.

[0028] Further design of the positioning plate 202 is preferred. The positioning plate 202 is an L-shaped plate, and the positioning plate 202 is provided with grooves 203 corresponding to the diagonal brace 201 at intervals. The grooves 203 facilitate the positioning plate 202 and the diagonal brace 201 to fit better and complete the welding and fixing.

[0029] To further improve the stability of the diagonal brace 201, this application also provides a reinforcing rib 204, which is also inclined. Specifically, one end of the reinforcing rib 204 is connected to the base frame 1, and the other end is connected to the top of the diagonal brace 201. The reinforcing rib 204 serves as a connector and forms a triangular support with the diagonal brace 201, thereby further improving the stability of the diagonal brace.

[0030] Specifically, in order to improve the stability of the base frame 1, the base frame 1 described in this application includes: Two crossbeams, 101, are installed at intervals; At least two longitudinal beams 102 are arranged between the transverse beams 101, and the longitudinal beams 102 are spaced apart along the length direction of the transverse beams 101. The diagonal brace 201 is installed on the longitudinal beam 102 at the tail end. The diagonal brace 201 is inclined outward. The positioning plate 202 is parallel to the longitudinal beams 102. Several rollers 103 are installed at the bottom of the crossbeam 101; the rollers 103 in this application serve as auxiliary moving parts to facilitate the stable movement of the entire electric seat; the longitudinal beams 102 and the crossbeams 101 in the base frame 1 are connected to each other to ensure the stability of the bottom, and the stability of the support frame 3 is improved by installing diagonal braces 201 on a single longitudinal beam 102.

[0031] like Figure 2 As shown, the linkage mechanism 4 in this application is for extending or retracting the bench. Its specific structure can be existing, requiring only the above functions, or it can have the following structure, including: Support rod 401, the end of which is movably connected to the diagonal brace 201; The assembly plate 402 is installed on the support frame 3. Specifically, the assembly plate 402 is located on the inner wall of the support frame 3 and serves as the hinge point for the subsequent linkage mechanism movement. The first bench assembly 403 is movably connected to the end of the support rod 401 and then cooperates with the support frame 3; The top of the second bench assembly 404 is movably connected to the assembly plate 402, and the middle part of the second bench assembly 404 is movably connected to the first bench assembly 403. The third bench assembly 405 is movably connected to the ends of the first bench assembly 403 and the second bench assembly 404.

[0032] This application enables the switching between sitting and reclining postures through the cooperation of multiple components.

[0033] Specifically, the first bench assembly 403 in this application includes: The first bench connecting rod 406 is movably connected at its top to the assembly plate 402 and the support rod 401 respectively. The assembly plate 402 has an arc-shaped groove, and the shaft connecting the first bench connecting rod 406 and the support rod 401 is located inside the arc-shaped groove, thereby completing the extension of the entire linkage mechanism; at the same time, the lower part of the first bench connecting rod 406 is also movably connected to the assembly plate 402. The first bench transition rod 407 is connected at one end to the bottom of the first bench connecting rod 406 and at the other end to the third bench assembly 405. The first bench transition rod 407 is a long rod, which facilitates subsequent extension and helps to achieve zero-gravity lying flat. At least two first bench connecting plates 408 are respectively installed on the first bench transition rod 407 and the first bench connecting rod 406. The first bench connecting plates 408 are for subsequent support.

[0034] In one embodiment, the second bench assembly 404 includes: The second bench connecting rod 409 is movably connected to the assembly plate 402 at its top. The second bench transition rod 410 has one end movably connected to the bottom of the second bench connecting rod 409 and the other end movably connected to the third bench assembly 405. The second bench transition rod 410 is located outside the first bench connecting rod 406, and the second bench transition rod 410 is movably connected to the first bench connecting rod 406. This ensures that the second bench transition rod 410 will not interfere with the first bench transition rod 407 when it rotates. The second bench connecting plate 411 is installed on the second bench transition rod 410.

[0035] The third bench assembly 405 includes: The bench frame 412 is movably connected to the ends of the second bench transition rod 410 and the first bench transition rod 407; The third bench connecting plate 413 is installed on the side of the bench frame 412; this application has three components to facilitate the user's lying down.

[0036] Further explanation is provided regarding this application: The embodiments of this application disclose a coordinated adjustment mechanism that can be applied to different electric seats to achieve zero-gravity extension.

[0037] Specifically, during operation, the support frame 3 is rotated by the drive unit 5 (electric push rod). At this time, the first bench assembly 403 rotates around the assembly plate 402, thereby causing the second bench assembly 404 and the third bench assembly 405 to extend, thus achieving zero-gravity support.

[0038] This application also discloses an electric seat that includes the aforementioned coordinated adjustment mechanism.
