Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0029] In the description of this utility model, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] The specific implementation of this utility model is as follows:

[0031] like Figures 1-5 As shown, this utility model provides an auxiliary standing seat to improve the sitting experience, comprising:

[0032] Mechanical extension device 1 is configured to change shape under the action of actuator 4 to switch states;

[0033] A rocking base 3 is provided, and a mechanical extension device 1 is mounted on the rocking base 3. The rocking base 3 is configured to allow the mechanical extension device 1 to swing back and forth in response to an external force. The rocking base 3 includes a fixed seat 7 and two sets of swinging units arranged at intervals on the left and right. Each set of swinging units includes at least two swinging members arranged at intervals on the front and back. The swinging members suspend the mechanical extension device 1 on the fixed seat 7. At least two sets of limiting components are provided between the swinging units and the mechanical extension device 1.

[0034] The limiting assembly comprises a limiting member and a limiting groove, the limiting member is arranged on one of the swing member or the mechanical stretching device 1, and the limiting groove is arranged on the other one of the swing member or the mechanical stretching device 1; the limiting groove comprises a swing space and a locking end, the swing space is configured to gradually decrease in size when approaching the locking end;

[0035] The actuator 4 is configured to control the state switching; under the driving of the actuator 4, the seat has at least a first state and a second state, and has an intermediate state between the first state and the second state; when the seat is in the intermediate state, the limiting member of each set of limiting assemblies is located in the swing space of the limiting groove, at this time, the mechanical stretching device 1 can swing back and forth in response to external force; when the seat switches from the intermediate state to the first state, the limiting member of one set of limiting assemblies gradually moves from the swing space to the locking end, the swing amplitude of the mechanical stretching device 1 gradually decreases and stops swinging after the limiting member enters the locking end of the limiting groove; when the seat switches from the intermediate state to the second state, the limiting member of the other set of limiting assemblies gradually moves from the swing space to the locking end, the swing amplitude of the mechanical stretching device 1 also gradually decreases and stops swinging after the limiting member enters the locking end of the limiting groove; and the driving direction of the actuator 4 when switching from the intermediate state to the first state is opposite to the driving direction of the actuator 4 when switching from the intermediate state to the second state.

[0036] The first state and the second state are two different states, the actuator 4 is generally an electric push rod, and is divided into the first state and the second state according to the extension stroke of the actuator 4, the actuator 4 is in the first state when it is extended to the longest, and the actuator 4 is in the second state when it is shortened to the shortest, and the intermediate state is between the first state and the second state, so the first state and the second state are two completely different states, which can be selected according to specific application scenarios, for example, the first state is an auxiliary standing state, the second state is a lying state, and the intermediate state is a sitting state, which can also include a TV posture state, the first and second states are more functional relative to the intermediate state, and the seat is required to stop swinging and remain stable, while in the intermediate state, the seat can swing to increase the comfortable sitting feeling as much as possible; since the driving direction of the actuator 4 is different when switching to the first and second states, different limiting assemblies need to be set to ensure that the two states can be locked respectively.

[0037] The limiting groove occupies a certain space, the movable space of the limiting member decreases when the limiting member approaches the locking end, and is locked; that is, when switching to the first and second states, the limiting member gradually approaches the locking end, the space gradually decreases, and the swing angle also gradually decreases.

[0038] The mechanical stretching device 1 is a mechanical stretching device mainly composed of a plurality of connecting rod members; the swing angle size reflects the swing ability; the swing ability gradually changes with the state switching, especially when switching from the intermediate state to the first and second states, the swing ability gradually weakens, if the limiting groove is arranged on the fixed seat 7 instead of the two swing members, then it is impossible to achieve this gradual weakening effect, on the contrary, it may appear motion interference, causing the mechanism to be stuck, damaging the mechanism components, affecting the service life; since the swing member and the mechanical stretching device 1 can swing, the limiting assembly arranged between the swing member and the mechanical stretching device 1 can also swing, the swing limiting assembly can transition smoothly, preventing interference and sticking; the specific structure of the mechanical stretching device is not described here, and can be referred to CN202410179965.5.

[0039] In summary, the seat is an electric sofa, the mechanical stretching device 1, i.e. the mechanical stretching device, realizes the conversion between different states when the internal connecting rod member moves; the swing base 3 provides a basic support and flexible movement condition for the swing of the seat, the mechanical stretching device 1 is stably arranged on the swing base 3 and can make the mechanical stretching device 1 respond to the action of external force and swing freely forward and backward; the actuator 4 is the “power engine” of the whole mechanism, which is configured to accurately control the switching of the state, and divides the first state, the intermediate state and the second state in turn from long to short, i.e. the auxiliary standing state, the sitting state, the TV state and the lying state; in the limiting assembly, the limiting groove ingeniously limits the activity range of the limiting member, thereby realizing the control of the swing amplitude of the mechanical stretching device 1.

[0040] Further, in the embodiment, the first state is the auxiliary standing state, the second state is the lying state, and the intermediate state includes the sitting state and the TV state, and the TV state is located between the sitting state and the lying state. In different states, the swing effect is different, in the sitting state, the swing ability is complete, but in the lying and auxiliary standing states, the swing needs to be locked to keep stable; and when switching from the sitting state to the lying state or the standing state, the swing ability gradually weakens until it is completely locked, i.e. when the sitting state is switched to the TV state, the swing ability is weakened, and when it is further switched to the lying state, the swing is locked.

[0041] The mechanical stretching device, the first swing member 8, the second swing member 9 and the fixed seat 7 constitute a four-bar linkage mechanism for rocking, and the rocking base can drive the mechanical stretching device to swing as a whole, so as to give the seat rocking ability, which is more close to the rocking chair experience preferred by the old people, and the mechanical stretching device can still perform the original state switching, realizing its rich functionality, especially the standing assistance function; therefore, the improvement of the seat is particularly aimed at the old people, which is more in line with the preferences and standing assistance function of the old people, so as to improve the competitiveness and increase the market share.
