Description

Technical Field

[0001] This invention relates to the field of seat accessories technology, specifically to a seat bracket. Background Technology

[0002] The seat frame is an important component of a seat. Existing seat frames generally have functions such as sitting, lying down, and leg-crossing. However, some special users need to achieve a head-down, feet-up lying position on the seat to accelerate blood flow from the feet to the head, or to achieve other purposes. To meet the needs of special users, Chinese Patent Publication No. CN109124120B discloses an iron frame for a standing recliner and its working method. By setting an inclined support, the telescopic support can be extended and driven by a first electric push rod to raise the front end of the base frame, allowing the user to achieve the head-down, feet-up function when lying down. However, the iron frame for this standing recliner has a complex structure and poor stability.

[0003] The technical problem to be solved by this invention is to provide a seat bracket that has a forward tilting function and has a simple and stable structure. Utility Model Content

[0004] To solve the above-mentioned technical problems, this invention provides a seat bracket, including a base frame. At least three support legs are provided at the bottom of the base frame. Fixed rods are vertically arranged on the left and right sides of the rear side frame of the base frame. A swing rod is movably connected to the top of each fixed rod. A support frame is provided between the front bottom sides of the left and right swing rods. A bracket body is provided above the support frame. Limiting plates are provided on the left and right sides of the front end of the support frame. A front support rod extending upwards is provided on the front side frame of the support frame. An electric actuator is movably connected to the top of the front support rod. The end of the electric actuator away from the front support rod is movably connected to the front side frame of the base frame. The electric actuator drives the support frame to rotate, switching the support frame between a horizontal position and a forward-tilted position. In the horizontal position, the support frame is horizontally positioned and located inside the base frame, with the limiting plates abutting against the top surface of the base frame. In the forward-tilted position, the front end of the support frame is tilted upwards.

[0005] In a further preferred embodiment, the fixed rod and the swing rod are respectively grooved, and the left and right side walls of the swing rod are movably connected to the left and right side walls of the fixed rod, respectively. There are two front support rods, which are symmetrically arranged on the left and right sides of the front side frame of the support frame. The tops of the two front support rods are movably connected to one end of the electric push rod, respectively; the structure of the seat bracket is more stable.

[0006] In a further preferred embodiment, the support body includes a pair of top support rods, which are symmetrically arranged above the support frame. The front end of each top support rod is provided with a footrest telescopic assembly, and the rear end of each top support rod is provided with a backrest assembly. The rear end of the bottom frame is provided with a first driving device for synchronously extending or retracting the left and right footrest telescopic assemblies. The front side of the bottom frame is provided with a second driving device for synchronously driving the left and right backrest assemblies. The backrest assembly includes a vertical state and a reclining state. When the backrest assembly is in the vertical state, it enables the user's back to be in a vertical position; when the backrest assembly is in the reclining state, it enables the user's back to be in a reclining position.

[0007] A method for operating the aforementioned seat bracket includes the following steps:

[0008] 1) In the initial state, the support frame is in a horizontal position, the footrest telescopic component is in a retracted state, and the backrest component is in a vertical state, which allows the user's legs to rest and their back to be in a vertical position (i.e., a sitting posture):

[0009] 2) The electric actuator drives the support frame to rotate, causing the front end of the support frame to tilt upwards and be set at an angle. At this time, the support frame is in a forward tilted state, which can realize the user's overall backward tilting state (i.e., a reclining posture).

[0010] 3) The first driving device drives the left and right footrest telescopic components to extend synchronously, so that the user's legs and feet are raised and the head is lower than the feet (i.e., the upturned posture).

[0011] The beneficial effects of this invention are as follows: During operation, the electric actuator drives the support frame to rotate, switching the support frame between a horizontal position and a forward-tilting position. When the support frame is in the horizontal position, it is horizontally positioned and located inside the bottom frame, with the limiting plate abutting against the top surface of the bottom frame. Because the support frame is located inside the bottom frame, the structure of the seat bracket is more compact. When the support frame is in the forward-tilting position, the front end of the support frame is tilted upwards. The seat bracket of this invention has a forward-tilting function, and its structure is simple and stable. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0023] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this new embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0024] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixation," etc., should be interpreted broadly. For example, "fixation" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1

[0025] like Figure 1-8A seat support includes a base frame 1, with four support legs 2 arranged at the corners of the bottom of the base frame 1. Fixed rods 3 are vertically mounted on the left and right sides of the rear side frame of the base frame 1. A swing rod 4 is movably connected to the top of each fixed rod 3. A support frame 5 is located between the front bottom sides of the left and right swing rods 4. A support body is located above the support frame 5. Limiting plates 7 are located on the left and right sides of the front end of the support frame 5. A front support rod 8 extending upwards is located on the front side frame of the support frame 5. An electric actuator 9 is movably connected to the top of the rod 8. The end of the electric actuator 9 away from the front support rod 8 is movably connected to the front side frame of the bottom frame 1. The electric actuator 9 drives the support frame 5 to rotate, so that the support frame 5 switches between a horizontal position and a forward tilted position. When the support frame 5 is in the horizontal position, it is horizontally set and located inside the bottom frame 1, and the limiting plate 7 abuts against the top surface of the bottom frame 1. When the support frame 5 is in the forward tilted position, the front end of the support frame 5 is tilted upward and tilted.

[0026] Preferably, the fixed rod 3 and the swing rod 4 are respectively grooved, and the left and right side walls of the swing rod 4 are movably connected to the left and right side walls of the fixed rod 3, respectively. There are two front support rods 8, which are symmetrically arranged on the left and right sides of the front side frame of the support frame 5. The tops of the two front support rods 8 are movably connected to one end of the electric push rod 9, respectively; the structure of the seat bracket is more stable.

[0027] Preferably, the support body includes a pair of top support rods 10, which are symmetrically arranged above the support frame 5. The front end of each top support rod 10 is provided with a footrest telescopic assembly 11, and the rear end of each top support rod 10 is provided with a backrest assembly 12. The rear end of the bottom frame 1 is provided with a first driving device 13 for driving the left and right footrest telescopic assemblies 11 to extend or retract synchronously. The front side of the bottom frame 1 is provided with a second driving device 14 for driving the left and right backrest assemblies 12 to move synchronously. The backrest assembly 12 includes a vertical state and a reclining state. When the backrest assembly 12 is in the vertical state, it enables the user's back to be in a vertical state. When the backrest assembly 12 is in the reclining state, it enables the user's back to be in a reclining state. Example 2

[0028] A method for operating the seat bracket according to Embodiment 1 includes the following steps:

[0029] 1) In the initial state, the support frame 5 is in a horizontal position, the footrest telescopic assembly 11 is in a retracted state, and the backrest assembly 12 is in a vertical state, which allows the user's legs to rest and their back to be in a vertical position (i.e., a sitting posture):

[0030] 2) The electric actuator 9 drives the support frame 5 to rotate, causing the front end of the support frame 5 to tilt upwards and be set at an angle. At this time, the support frame 5 is in a forward tilting state, which can realize the user's overall backward tilting state (i.e., a reclining posture).

[0031] 3) The first driving device 13 drives the left and right footrest telescopic components 11 to extend synchronously, so that the user's legs and feet are raised and the head is lower than the feet (i.e., the upturned posture).

[0032] During operation, the electric actuator 9 drives the support frame 5 to rotate, causing the support frame 5 to switch between a horizontal position and a forward-tilted position, as shown below. Figure 1 When the support frame 5 is in a horizontal position, it is horizontally positioned and located inside the base frame 1. The limiting plate 7 abuts against the top surface of the base frame 1. Because the support frame 5 is located inside the base frame 1, the structure of the seat bracket is more compact. Figure 2 When the support frame 5 is in a forward tilting state, the front end of the support frame 5 is tilted upwards and tilted; the seat bracket of this embodiment has a forward tilting function, and its structure is simple and stable.

[0033] The above description is the preferred embodiment of this invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention.
