Description

Technical Field

[0001] This utility model relates to the field of electric sofa testing technology, specifically to an auxiliary tooling 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 in order to assess its durability and potential defects.

[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 ergonomically designed and includes a headrest, backrest, and leg rest that are rotatably connected in sequence, thus simulating the user's posture and making the test results more realistic and reliable. The counterweights on each seat simulate human body parts. However, while this testing device can simulate the user's posture and make the test results more realistic and reliable, it is inconvenient to adjust the position of the counterweights. This not only hinders the control of load size and force points, reducing the versatility of the tooling, but also makes it difficult to adapt to various lifespan testing requirements, resulting in high testing costs and hindering its widespread use. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide an auxiliary tooling for testing the lifespan of electric sofas. It can effectively solve the problems in the prior art, such as the inconvenience of adjusting the position of the counterweight, the inconvenience of controlling the load size and force point, the limited versatility of the tooling, the inconvenience of adapting to various lifespan testing needs, the high testing cost, and the inconvenience of widespread use.

[0005] The technical solution adopted by this utility model is: an auxiliary tooling for testing the lifespan of an electric sofa, including a leg assembly, a footrest assembly and a backrest assembly, wherein a first connecting rod is fixedly installed at one end of the leg assembly near the footrest assembly, and a second connecting rod is fixedly installed at one end of the leg assembly near the backrest assembly; The leg assembly includes a leg frame, and a placement groove is provided along the inner edge of the leg frame. A counterweight is placed in the leg frame through the placement groove. The footrest assembly includes a footrest frame, a placement groove 2 is provided along the inner edge of the footrest frame, a baffle is fixedly installed at the end of the footrest frame away from the leg assembly, and a counterweight 2 is provided on the footrest frame through the placement groove 2. The backrest assembly includes a backrest frame, and a placement groove three is provided along the inner edge of the backrest frame. A counterweight three and a counterweight four are placed on the backrest frame through the placement groove three, and the counterweight three and the counterweight four are respectively located at both ends of the backrest frame.

[0006] Preferably, the leg assembly is rotatably mounted with a footrest assembly via a first connecting rod, and the leg assembly is rotatably mounted with a backrest assembly via a second connecting rod.

[0007] The above technical solution allows the leg assembly, footrest assembly, and backrest assembly to be placed on the electric sofa under test. The leg assembly is then rotatably connected to the footrest assembly via a first connecting rod and to the backrest assembly via a second connecting rod. This simulates the linkage motion of the electric sofa during actual use and facilitates the simulation of the angle changes of the footrest assembly and backrest assembly, thereby testing the durability of the parts.

[0008] Preferably, a limiting groove is formed through both sides of the leg frame, and a limiting bolt is threadedly connected to the inner edge of the limiting groove, and the limiting bolt abuts against the counterweight.

[0009] The above technical solution, through the design of counterweight one, can simulate the pressure of a user's legs on the sofa. Combined with the design of the upper limit bolt, the counterweight one can be prevented from shifting due to repeated extension and retraction of the leg assembly during testing, thus avoiding its easy fall and affecting normal testing. Preferably, there are multiple identical limiting grooves, and the multiple limiting grooves are distributed at equal intervals.

[0010] The above technical solution, through the design of multiple limiting grooves, allows for easy adjustment of the number and position of counterweights according to test standards, simulating users of different weights. It also facilitates control of load size and force points, improves the versatility of the tooling, adapts to various life test requirements, and allows multiple sets of tests to be completed without changing the leg frame, thus reducing test costs.

[0011] Preferably, the cross-section of the baffle frame is L-shaped, and the length of the end of the baffle frame closest to the second placement groove is 1 / 3 of the length of the second placement groove.

[0012] Through the above technical solution, the "L"-shaped baffle design allows its horizontal part to extend from the edge of the foot support frame and its vertical part to fit against the inner wall of the second placement slot. During repeated extension and retraction tests of the foot support assembly, it prevents the second counterweight from sliding out of the second placement slot due to inertia, thus ensuring test safety and preventing the second counterweight from slipping and damaging the equipment or affecting the test.

[0013] Preferably, the inner edge of the backrest frame is provided with positioning groove 1 and positioning groove 2, and the counterweight block 3 is provided with positioning groove 3 and positioning groove 4 at one end near positioning groove 1 and positioning groove 2. Positioning groove 1 and positioning groove 3 correspond one-to-one, and positioning groove 2 and positioning groove 4 correspond one-to-one.

[0014] Through the above technical solution, by cooperating with positioning slot 1 and positioning slot 3, as well as positioning slot 2 and positioning slot 4, when a longer counterweight block 3 is selected, it can be limited by positioning slot 1 and positioning slot 3, while when a shorter counterweight block 4 is selected, it can be limited by positioning slot 4. The weight of the counterweight block can be adjusted according to different situations. Furthermore, counterweight block 3 and counterweight block 4 are located at both ends of the backrest frame, which facilitates heavier force on one side and facilitates further auxiliary testing.

[0015] Preferably, a long screw rod is threadedly connected to the inner edge of positioning groove one, positioning groove two, positioning groove three and positioning groove four, and nuts are threadedly connected to both ends of the long screw rod away from the backrest frame. A limit seat is fixedly installed at the end of the backrest frame away from the leg assembly.

[0016] Through the above technical solution, and with the design of the long screw and nut, when the appropriate counterweight three and counterweight four are selected, they can be fixed to the backrest frame through the long screw, thereby preventing the backrest of the electric sofa from falling off when it moves. In addition, with the design of the upper limit seat, the entire auxiliary fixture can be connected to the electric sofa through the straps to prevent it from falling off easily.

[0017] Compared with the prior art, this utility model provides an auxiliary tooling for testing the lifespan of an electric sofa, which has the following beneficial effects: 1. The auxiliary fixture for testing the lifespan of the electric sofa can place the leg assembly, footrest assembly, and backrest assembly on the electric sofa under test. The leg assembly is then rotatably connected to the footrest assembly via a first connecting rod and to the backrest assembly via a second connecting rod. This can simulate the linkage movement of the electric sofa during actual use and can easily simulate the angle change state of the footrest assembly and backrest assembly, thereby testing the durability of its parts. 2. This auxiliary fixture for testing the lifespan of electric sofas allows for adjustment of the position of the counterweights on the backrest and leg frames according to actual conditions. It facilitates the adjustment of the number and position of counterweights based on the test standards and to simulate users of different weights. This enables control over the load size and stress points, improves the versatility of the fixture, and allows it to adapt to various lifespan testing needs. Multiple sets of tests can be completed without replacing the leg frames, reducing testing costs. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: As Figure 1-8 As shown, the present invention provides an auxiliary tooling for testing the lifespan of an electric sofa, including a leg assembly 1, a footrest assembly 3, and a backrest assembly 5. A first connecting rod 2 is fixedly installed at one end of the leg assembly 1 near the footrest assembly 3, and a second connecting rod 4 is fixedly installed at one end of the leg assembly 1 near the backrest assembly 5. The leg assembly 1 includes a leg frame 101, and a placement groove 102 is provided at the inner edge of the leg frame 101. A counterweight 105 is placed in the leg frame 101 through the placement groove 102. The foot support assembly 3 includes a foot support frame 301, a placement groove 302 is provided on the inner edge of the foot support frame 301, a baffle 303 is fixedly installed on the end of the foot support frame 301 away from the leg assembly 1, and a counterweight 304 is provided on the foot support frame 301 through the placement groove 302. The backrest assembly 5 includes a backrest frame 501. A placement groove 3 504 is provided at the inner edge of the backrest frame 501. A counterweight 3 505 and a counterweight 4 507 are placed on the backrest frame 501 through the placement groove 3 504. The counterweight 3 505 and the counterweight 4 507 are located at the two ends of the backrest frame 501, respectively.

[0022] Specifically, the leg assembly 1 is rotatably mounted with the footrest assembly 3 via the first connecting rod 2, and the leg assembly 1 is rotatably mounted with the backrest assembly 5 via the second connecting rod 4. The advantage is that the leg assembly 1, footrest assembly 3, and backrest assembly 5 can be placed on the electric sofa under test. Then, the leg assembly 1 is rotatably connected to the footrest assembly 3 via the first connecting rod 2, and to the backrest assembly 5 via the second connecting rod 4. This can simulate the linkage movement of the electric sofa during actual use during testing, and can easily simulate the angle change state of the footrest assembly 3 and the backrest assembly 5, thereby testing the durability of its parts.

[0023] Specifically, limit grooves 103 are provided on both sides of the leg frame 101. Limit bolts 104 are threadedly connected to the inner edge of the limit grooves 103. The limit bolts 104 abut against the counterweight 105. The advantage is that the design of the counterweight 105 can simulate the pressure of the user's legs on the sofa. With the design of the limit bolts 104, the counterweight 105 can be prevented from shifting due to repeated extension and retraction of the leg assembly 1 during the test, thus avoiding it from falling off and affecting the normal test.

[0024] Specifically, multiple limit slots 103 are provided, and the multiple limit slots 103 are distributed at equal intervals. The advantage is that the design of multiple limit slots 103 makes it easy to adjust the number and position of counterweights 105 according to the test standards, simulating users of different weights. It also makes it easy to control the load size and force point, improve the versatility of the tooling, adapt to various life test requirements, and complete multiple sets of tests without changing the leg frame 101, thus reducing test costs.

[0025] Example 2: Figure 2-8 As shown, this is an improvement on the previous embodiment.

[0026] Specifically, the baffle frame 303 has an "L" shaped cross-section. The length of the end of the baffle frame 303 closest to the second placement slot 302 is 1 / 3 of the length of the second placement slot 302. The advantage is that the "L" shaped baffle frame 303 design allows its lateral part to extend from the edge of the foot support frame 301 and its longitudinal part to fit against the inner wall of the second placement slot 302. During repeated extension and retraction tests of the foot support assembly 3, it prevents the counterweight 304 from sliding out of the second placement slot 302 due to inertia, thus ensuring test safety and preventing the counterweight 304 from slipping off and damaging the equipment or affecting the test.

[0027] Specifically, positioning groove 1 502 and positioning groove 2 503 are provided on the inner edge of the backrest frame 501. Positioning groove 3 505 has positioning groove 3 506 and positioning groove 4 508 at the end near positioning groove 1 502 and positioning groove 2 503. Positioning groove 1 502 and positioning groove 3 506 correspond one-to-one, and positioning groove 2 503 and positioning groove 4 508 correspond one-to-one. The advantage is that, through positioning groove 1 502 and positioning groove 3 506, as well as positioning groove 2 503 and positioning groove 4 508... The positioning groove 4 508 is used to limit the movement of a longer counterweight 3 505 through positioning groove 1 502 and positioning groove 3 506, while the shorter counterweight 4 507 can be limited through positioning groove 4 508. The weight of the counterweight can be adjusted according to different situations. Furthermore, the counterweight 3 505 and counterweight 4 507 are located at the two ends of the backrest frame 501, which facilitates heavier force on one side and further auxiliary testing.

[0028] Specifically, long screws 509 are threaded along the inner edges of positioning grooves 502, 503, 506, and 508. Nuts 510 are threaded onto both ends of the long screws 509 away from the backrest frame 501. A limit seat 6 is fixedly installed at the end of the backrest frame 501 away from the leg assembly 1. The advantage is that, through the design of the long screws 509 and nuts 510, when appropriate counterweights 505 and 507 are selected, they can be fixed to the backrest frame 501 by the long screws 509, thereby preventing the backrest of the electric sofa from easily falling off when it moves. In addition, with the design of the limit seat 6, the entire auxiliary fixture can be connected to the electric sofa by straps, preventing it from easily falling off.

[0029] Working principle: During use, the leg assembly 1, footrest assembly 3, and backrest assembly 5 can be placed on the electric sofa under test. The leg assembly 1 is then rotatably connected to the footrest assembly 3 via the first connecting rod 2, and to the backrest assembly 5 via the second connecting rod 4. This simulates the coordinated movement of the electric sofa during actual use, and allows for easy simulation of the angle changes of the footrest assembly 3 and backrest assembly 5, thereby testing the durability of the components. The design of the counterweight 105 simulates the pressure of the user's legs on the sofa, and the upper limit bolt 104, through threaded locking, prevents… During testing, the leg assembly repeatedly extends and retracts the counterweight 105 to prevent it from easily falling off and affecting normal testing. The design of multiple limiting slots 103 allows for easy adjustment of the number and position of the counterweight 105 according to testing standards, simulating users of different weights. This facilitates control over load size and stress points, improves the versatility of the tooling, and adapts to various lifespan testing needs. Multiple sets of tests can be completed without replacing the leg frame 101, reducing testing costs. The "L"-shaped baffle frame 303 design allows its lateral portion to extend from the edge of the footrest frame 301. The longitudinal portion fits against the inner wall of the placement slot 2 302. During repeated extension and retraction tests of the foot support assembly 3, it prevents the counterweight block 2 304 from sliding out of the placement slot 2 302 due to inertia, ensuring test safety and preventing the counterweight block 2 304 from slipping off and damaging the equipment or affecting the test. Through the cooperation of positioning slot 1 502 and positioning slot 3 506, as well as positioning slot 2 503 and positioning slot 4 508, when a longer counterweight block 3 505 is selected, it can be limited by positioning slot 1 502 and positioning slot 3 506, while when a shorter counterweight block 4 507 is selected, it can be limited by positioning slot 4 508. This can be adjusted according to different... The weight of the counterweights can be adjusted according to the situation. Counterweights 3 (505) and 4 (507) are located at both ends of the backrest frame 501, which facilitates heavier force on one side and further auxiliary testing. Through the design of the long screw 509 and nut 510, when the appropriate counterweights 3 (505) and 4 (507) are selected, they can be fixed to the backrest frame 501 by the long screw 509, thereby preventing the backrest of the electric sofa from falling off when it moves. In addition, with the design of the upper limit seat 6, the entire auxiliary fixture can be connected to the electric sofa by straps to prevent it from falling off easily.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
