Description

Technical Field

[0001] This utility model relates to the field of sofa technology, and in particular to an intelligent electric sofa based on ergonomics. Background Technology

[0002] A sofa is a backrest chair with a soft backrest, usually fitted with springs or thick foam padding, and typically has armrests on both sides. It generally consists of a backrest, seat, armrests, and legs, providing a comfortable sitting or reclining experience. Its soft cushions and backrest allow the body to relax and reduce fatigue. Whether sitting to read, watch TV, chat, or lying down for a nap, a sofa offers comfort.

[0003] For example, patent application number CN212754962U specifically discloses CN216723889U, which includes the arrangement of a sofa seat, backrest, first enclosure, second enclosure, rollers, drive mechanism, first lifting shaft and support plate, so that it can be adjusted in a moving state or a fixed state, making adjustment convenient and flexible to use. When in a moving state, the sofa can be moved freely by means of the rollers.

[0004] When the aforementioned patent is in use, dust accumulates in the gap between the sofa seat and the floor over time. Because this gap is relatively narrow, brooms and mops have difficulty reaching it during routine cleaning. Dust, hair, and small debris easily accumulate there, and the dust buildup can breed bacteria, mites, and pests such as cockroaches and rats, which may inhabit and reproduce in this dark space. This not only pollutes indoor air but may also pose a threat to human health. Utility Model Content

[0005] This utility model provides an ergonomically based smart electric sofa to address the problem in the aforementioned patent where dust accumulates in the gap between the sofa seat and the ground after prolonged use. Because this gap is relatively narrow, brooms and mops have difficulty reaching it during daily cleaning. Dust, hair, and small debris easily accumulate there, and the dust buildup also promotes bacterial growth.

[0006] This utility model embodiment adopts the following technical solution: an ergonomically based intelligent electric sofa. It mainly includes: a sofa seat with a groove at its bottom and a side slot on the groove; a dust-blocking mechanism installed in the side slot, the dust-blocking mechanism having a barrier that blocks the gap between the sofa seat and the ground and is pushed and held by a first spring member; and a fixing unit installed on the barrier, the fixing unit having a hanging rod for fixing the position of the barrier and a hook member adapted to the hanging rod.

[0007] Furthermore, the sofa seat includes a sofa cushion and a backrest is provided on the sofa seat.

[0008] Furthermore, a lifting mechanism is installed in the groove, and the lifting mechanism is installed on the mounting plate in the groove. The mounting plate has protrusions at both ends. The protrusion at the upper end is defined as the first protrusion, and the protrusion at the lower end is defined as the second protrusion. A second drive source is installed on the first protrusion, and a lead screw is installed at the output end of the second drive source.

[0009] A support seat is threaded onto the lead screw, and two sets of limiting rods are installed between the first protrusion and the second protrusion. The support seat movably passes through the two sets of limiting rods.

[0010] Furthermore, auxiliary pads are installed on the side of the support base.

[0011] Furthermore, the dust-blocking mechanism also includes a mounting box installed in the side slot, the mounting box having an opening slot, the first spring being installed at the top of the inner wall of the opening slot, a sliding block being slidably installed in the opening slot, and the enclosure being installed between four sets of the sliding blocks.

[0012] Furthermore, the fixing unit also includes a mounting base installed on the enclosure, with hinge rods rotatably connected to both sides of the mounting base. A second spring is installed at one end of each hinge rod, and the hanging rod is connected between two sets of the second springs. The hook is installed at the bottom of the mounting box.

[0013] Furthermore, the bottom of the sofa seat is provided with a self-moving mechanism, which has rollers for moving the sofa and a first drive source for driving the rollers to rotate, as well as pulleys that move synchronously with the rollers.

[0014] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects:

[0015] An ergonomically designed smart electric sofa features a sliding block that, under the action of a first spring, causes the barrier to be pressed against the ground, creating a barrier between the bottom of the sofa seat and the ground. This effectively prevents dust from accumulating on the bottom of the sofa and reduces the hassle of cleaning it. When the sofa needs to be moved, the barrier is secured using a hanging rod and hooks. Once the sofa is moved to a new location, the hooks can be easily released, allowing the barrier to return to its ground-pressing position under the action of the springs, continuing to block dust.

[0026] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0027] The technical solutions provided by the various embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 6 As shown, this utility model embodiment provides an ergonomically based intelligent electric sofa, which mainly includes a sofa seat 1, a self-moving mechanism 4, a lifting mechanism 5, and a dust-blocking mechanism 6.

[0029] The sofa seat 1 includes a sofa cushion 2 for enhancing comfort, and a backrest 3 for providing support for the user's back. A groove 11 is provided at the bottom of the sofa seat 1, and a side groove 12 is provided in the groove 11.

[0030] The self-moving mechanism 4 includes a support frame 41 installed at the bottom of the sofa seat 1, and two sets of first drive sources 42 are fixedly installed on the support frame 41. Rollers 43 are fixedly installed at the output end of the first drive sources 42, and pulleys 44 are fixedly installed on the support frame 41 at the end away from the rollers 43.

[0031] The first drive source 42 is used to start the machine, so as to drive the roller 43 to rotate and simultaneously drive the pulley 44 to move. Thus, the rotation of the roller 43 and the cooperation of the pulley 44 can move the sofa seat 1, which solves the problem of the sofa being fixed in position and difficult to move. For example, it is convenient to clean the dust under the sofa or rearrange the indoor furniture.

[0032] In some practical applications, refer to Figures 2-3 As shown, the lifting mechanism 5 includes a mounting plate 51 fixedly installed in the groove 11. The mounting plate 51 has protrusions at both ends (not shown in the figure) to... Figure 3 For example, the protrusion at the upper end is defined as the first protrusion, and the protrusion at the lower end is defined as the second protrusion. A second drive source 52 is fixedly installed on the first protrusion, and a lead screw (not shown in the figure) is fixedly installed at the output end of the second drive source 52, and the other end of the lead screw is connected to the bearing of the second protrusion.

[0033] A support seat 53 is threaded onto the lead screw, and two sets of limiting rods 54 are fixedly installed between the first protrusion and the second protrusion. The support seat 53 is movably inserted through the two sets of limiting rods 54. The lead screw is adapted to rotate with the output end of the second drive source 52 to drive the support seat 53 to move up and down.

[0034] Furthermore, a support foot 55 is fixedly installed on the support base 53. The support foot 55 is suitable for moving synchronously with the movement of the support base 53 to adjust the height of the sofa seat 1 to be closer to or further away from the ground. At the same time, an auxiliary pad foot 56 is fixedly installed on the side of the support base 53. The auxiliary pad foot 56 is suitable for providing auxiliary support for the sofa seat 1.

[0035] In other practical applications, refer to Figures 2-5As shown, the dust-blocking mechanism 6 is used to cover the gap between the ground and the sofa to prevent dust accumulation. The dust-blocking mechanism 6 includes a mounting box 61 fixedly installed in the side slot 12 (specifically, in actual application, mounting boxes 61 are provided at the four corners of the sofa, that is, there are four sets of side slots 12). An opening slot 62 is provided on the mounting box 61, and a first spring member 63 is fixedly installed at the top of the inner wall of the opening slot 62. At the same time, a sliding block 64 is slidably installed in the opening slot 62. All four sets of sliding blocks 64 are fixedly installed on the barrier 65. The barrier 65 serves as a barrier to protect the inside of the sofa from dust and other debris.

[0036] The sliding block 64, under the action of the first spring 63, drives the barrier 65 to press against the ground, thus forming a barrier between the bottom of the sofa seat 1 and the ground. Dust and other debris have difficulty entering the gap between the bottom of the sofa seat 1 and the ground through this barrier, effectively preventing dust from accumulating on the bottom of the sofa, reducing the hassle of cleaning the bottom of the sofa, and helping to maintain a clean home environment.

[0037] In some practical applications, refer to Figures 3-5 As shown, a fixing unit is installed on the enclosure 65. The fixing unit includes a mounting base 66 fixedly installed on the enclosure 65, and hinge rods 67 are rotatably connected to both sides of the mounting base 66. A second spring member 68 is fixedly installed at one end of the hinge rod 67, and a hanging rod 69 is connected between the two sets of second spring members 68. At the same time, a hook member 610 adapted to the hanging rod 69 is fixedly installed at the bottom of the mounting box 61.

[0038] Therefore, when the sofa needs to be moved, by holding the mounting base 66, the barrier 65 is moved upward and the first spring 63 is compressed, so that the hanging rod 69 is hooked onto the hook 610, creating a certain distance between the barrier 65 and the ground. This facilitates the use of the self-moving mechanism 4 and the lifting mechanism 5, preventing damage to the self-moving mechanism 4 and the lifting mechanism 5 due to friction or collision if the barrier 65 is constantly pressed against the ground during sofa movement. Raising the barrier 65 a certain distance can prevent this from happening and extend the service life of these mechanisms. At the same time, the connection between the hanging rod 69 and the hook 610 fixes the position of the barrier 65. When the sofa is moved to a new position, the connection can be easily released, allowing the barrier 65 to return to the ground-pressing state under the action of the spring, continuing to play its role in blocking dust and maintaining the cleanliness of the home environment.

[0039] In conclusion, considering the comfort of the sofa, an ergonomic design concept is necessary. The following design scheme can be considered: The curves of the seat and backrest of the smart electric sofa are key to ergonomic design. The seat depth and width should be appropriate, generally around 45-55 cm deep and 50-60 cm wide. This ensures that the thighs are adequately supported and the buttocks do not feel cramped when the user sits down. The curve of the backrest should closely conform to the natural curve of the human spine, with corresponding support areas from the cervical to the lumbar spine. For example, in the cervical spine area, the backrest will have a slight forward bulge, about 10-15 cm high, which perfectly supports the user's neck and reduces pressure on the cervical spine; in the lumbar spine area, there is a backward indentation, about 3-5 cm deep, which can well conform to the lumbar spine, prevent the lower back from being unsupported, and maintain the normal physiological curvature of the spine.

[0040] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
