Description

Technical Field

[0001] This utility model relates to the field of electric sofa testing technology, specifically a modular testing fixture for testing the lifespan of an electric sofa. Background Technology

[0002] As a product that combines comfort and functionality in modern homes, electric sofas rely on an electric drive system, such as a push rod motor, control system, and mechanical transmission structure, such as a telescopic bracket and hinge connectors, to achieve actions such as backrest angle adjustment, seat depth extension, and leg support height adjustment. To ensure the reliability of the product in long-term use, life tests are required to simulate users' daily usage scenarios to assess its durability and potential defects. For life test fixtures, modular design is also an essential part.

[0003] Chinese Utility Model Patent Publication No. CN221038049U discloses an electric sofa testing device. The device, as described in the specification, uses a base and counterweights. The base is designed to mimic human anatomy and includes a headrest, backrest, and leg rest that are rotatably connected in sequence. This allows it to simulate a user's posture and body shape, making the test results more realistic and reliable. Counterweights are placed on each seat to simulate human body parts on the electric sofa. However, while this testing device can achieve multiple postures and body shape changes, it lacks a quick-connect and installation structure between multiple modules. This makes it inconvenient to disassemble and reassemble according to actual testing conditions, hindering the implementation of a multi-modal design. Consequently, the overall testing fixture has poor practicality and is not suitable for widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a modular testing fixture for testing the lifespan of electric sofas. It can effectively solve the problem in the prior art that the design of multiple modules lacks a quick connection and installation structure, making it inconvenient to disassemble and assemble according to the actual test conditions, thus making it difficult to realize a multi-modal design. As a result, the overall testing fixture has poor practicality and is not easy to promote and use.

[0005] The technical solution adopted by this utility model is: a modular testing fixture for testing the lifespan of an electric sofa, including a hip and leg module, a leg support module, a backrest module and a fixing module. The hip and leg module is rotatably connected to the leg support module and the backrest module. The fixing module is located at the end of the backrest module away from the leg support module. A counterweight is fixedly installed at the end of the backrest module away from the hip and leg module. A fastening bolt is threadedly connected to the end of the backrest module away from the hip and leg module. The leg support module includes a leg support frame, a positioning groove is provided at the inner edge of the leg support frame, a reserved groove and a slot are provided at the end of the leg support frame away from the hip and leg module, a counterweight is placed at the inner edge of the reserved groove, and a baffle and a side plate are snapped into the end of the leg support frame away from the hip and leg module.

[0022] Example 1: As Figure 1-7As shown, the present invention provides a modular testing fixture for testing the lifespan of an electric sofa, including a hip and leg module 1, a leg support module 7, a backrest module 13, and a fixing module 16. The hip and leg module 1 is rotatably connected to the leg support module 7 and the backrest module 13. The fixing module 16 is located at the end of the backrest module 13 away from the leg support module 7. A counterweight 14 is fixedly installed at the end of the backrest module 13 away from the hip and leg module 1, and a fastening bolt 15 is threadedly connected to the end of the backrest module 13 away from the hip and leg module 1. The leg support module 7 includes a leg support frame 701. A positioning groove 702 is provided at the inner edge of the leg support frame 701. A reserved groove 703 and a slot 704 are provided at the end of the leg support frame 701 away from the hip and leg module 1. A counterweight 705 is placed at the inner edge of the reserved groove 703. A baffle 708 and a side plate 709 are snapped onto the end of the leg support frame 701 away from the hip and leg module 1. The fixing module 16 includes a fixing seat 1601 and a fixing rod 1603. A connecting seat 1604 and a limiting frame 1605 are fixedly installed on the inner edge of the fixing rod 1603.

[0023] Specifically, a mounting plate 2 and a connecting shaft 4 are fixedly installed on one end of the hip and leg module 1 near the leg support module 7. A through groove 5 is provided on the inner edge of the connecting shaft 4. A connector 6 is rotatably installed on the connecting shaft 4 through the through groove 5. The connector 6 is fixedly installed on the leg support module 7. The advantage is that, through the design of the mounting plate 2 and the connecting shaft 4, when connecting the leg support module 7, the leg support module 7 can be aligned with the connecting shaft 4. Then, the connector 6 passes through the leg support module 7, which can realize the connection with the leg support module 7 and also realize the rotation between the two, which can facilitate the quick connection and disassembly of the two.

[0024] Specifically, the hip and leg module 1 is fixedly mounted with a mounting plate 2 8 and a connecting shaft 2 10 at one end near the backrest module 13. A through groove 2 11 is provided on the inner edge of the connecting shaft 2 10. A connector 2 12 is rotatably mounted on the connecting shaft 2 10 through the through groove 2 11. The connector 2 12 is fixedly mounted to the backrest module 13. The advantage is that, through the design of the mounting plate 2 8 and the connecting shaft 2 10, when connecting the backrest module 13, the backrest module 13 can be aligned with the connecting shaft 2 10. Then, the connector 2 12 passes through the backrest module 13, which can achieve both connection with the backrest module 13 and rotation between the two.

In addition, with the design of the positioning post 707 and the positioning hole 706, when the baffle 708 is connected, it can achieve quick alignment and avoid displacement during fixing.

[0028] Specifically, a fixing block 1602 is fixedly installed at the end of the fixing base 1601 away from the backrest module 13, and a fixing rod 1603 is fixedly installed at the end of the fixing block 1602 away from the fixing base 1601. The advantage is that the design of the fixing block 1602 and the fixing rod 1603 can easily fix the upper components, and can prevent the first limiting frame 1605 and the second limiting frame 1607 from easily shifting, thereby affecting normal use.

[0029] Specifically, limit frame 1605 and limit frame 2 1607 have the same structure. Limit frame 1605 and limit frame 2 1607 together form an "L" shape. The advantage is that, through the design of limit frame 1605 and limit frame 2 1607, when placing the overall tooling, the strap can pass through limit frame 2 1607, then go around the electric sofa and connect to limit frame 1 1605, which can realize the connection between the tooling and the electric sofa being tested, and can avoid displacement of the modular tooling.

[0030] Working Principle: During use, the design of mounting plate 2 and connecting shaft 4 allows for alignment of leg support module 7 with connecting shaft 4 when connecting it. Connector 6 then passes through leg support module 7, enabling both connection and rotation. This facilitates quick connection and disassembly. Similarly, the design of mounting plate 8 and connecting shaft 10 allows for alignment of backrest module 13 with connecting shaft 10 when connecting it. Connector 12 then passes through backrest module 13, enabling both connection and rotation. Combined with the quick-release design of leg support module 7, disassembly and assembly can be performed according to actual testing conditions. This also facilitates multi-modal design. The design of positioning bolts 3 and 9 allows for connection of mounting plates 2 and 8 with hip and leg module 1, enabling the bolts to pass through and then be tightened. The design allows for quick connection between mounting plates 1 and 2 and the hip and leg module 1. Combined with the design of connectors 1 and 2, multiple modular disassembly methods are available. The pre-drilled hole 711 allows adjustment of the connection length between the leg support frame 701 and the hip and leg module 1. Furthermore, the design of the positioning post 707 and positioning hole 706 enables quick alignment when connecting the baffle 708, preventing displacement during fixing. The design of the fixing block 1602 and fixing rod 1603 facilitates the fixing of the upper components, preventing displacement of the limiting frame 1605 and limiting frame 2 1607, which could affect normal use. The design of limiting frame 1605 and limiting frame 2 1607 allows for connection with the tested electric sofa by passing a strap through limiting frame 2 1607 and then around the electric sofa to connecting to limiting frame 1 1605, preventing displacement of the modular fixture.
