[0029] Referring to Figure 1, this embodiment provides an electric sofa testing device 100, including a control component 110, a drive component 120, a seat frame linkage component 130, and a counterweight component 150. One end of the drive component 120 is connected to the output end 116 of the control component 110, and the other end is drivenly connected to the seat frame linkage component 130. The seat frame linkage component 130 includes a backrest support 131, a seat cushion support 132, and a leg support 133 that are rotatably connected in sequence. At least one counterweight component 150 is provided on the support surface of each of the backrest support 131, seat cushion support 132, and leg support 133. The control component 110 can drive one or more of the backrest support 131, seat cushion support 132, and leg support 133 to rotate around the connection point through the drive component 120 to simulate the posture changes of an electric sofa.

[0030] Specifically, as shown in Figure 1, the electric sofa testing device 100 is configured to be placed on an electric sofa. The electric sofa testing device 100 consists of a control component 110, a drive component 120, a seat frame linkage component 130, and a counterweight component 150. The control component 110 includes a microcontroller 111, which receives and processes input signals, performs calculations and processing on test parameters, etc., to ensure that the electric sofa testing device 100 completes the test according to preset logic.

[0031] As shown in Figure 5, the output terminal 116 of the control component 110 is connected to a drive component 120, preferably an electric actuator 120. One end of the electric actuator is connected to the output terminal 116 of the control component 110, and the other end is driven by the frame linkage component 130. The microcontroller 111 can output a drive signal, and the electric actuator can drive the frame linkage component 130 to adjust different postures according to the drive signal.

[0032] As shown in Figure 2, the seat frame linkage assembly 130 includes a backrest support 131, a seat cushion support 132, and a leg support 133 that are rotatably connected in sequence. The electric push rod can drive one or more of the backrest support 131, seat cushion support 132, and leg support 133 to rotate around the connection point, realizing the conversion between sitting posture, movie-watching posture, and zero-gravity posture in actual use, thereby meeting the needs of life testing of electric sofas at different angles.

[0033] To simulate the load conditions of the human back, torso, and legs under different postures, as shown in Figure 1, at least one counterweight 150 is provided on the support surface of the backrest support 131, seat cushion support 132, and leg support 133. Preferably, the surface of the counterweight 150 is provided with a handle 151 to facilitate the assembly and replacement of the counterweight 150. In one specific embodiment of this application, the counterweight 150 is a weight.

[0034] It should be noted that, in one possible implementation of this application, firstly, this application does not impose any restrictions on the number and placement of counterweights 150 on the support surfaces of the backrest support 131, seat cushion support 132, and leg support 133. This application can increase or decrease the number of counterweights 150 or adjust the test position of the counterweights 150 according to actual test requirements, so as to make the test results more realistic and reliable.

[0035] Second, as shown in Figure 5, the power module 115 is connected to the input terminal 117 of the control component 110. The power module 115 provides voltage to each component in the control component 110 to ensure the normal operation of the electric sofa testing device 100. The control component 110 also includes a relay 112, and the microcontroller 111 is electrically connected to the relay 112. The microcontroller 111 connects or disconnects the power supply of the drive component 120 through the relay 112 at a preset cycle, thereby simulating the power-on and power-off states of the electric sofa testing device 100 during long-term use, accelerating the aging of the device, detecting the normal operating time of the electric sofa testing device 100 under frequent operation, and evaluating the lifespan of the device, making the testing process more flexible and reliable.

[0036] Third, as shown in Figure 3, the electric sofa testing device 100 also includes a dynamic counterweight frame 160 mounted on the seat frame linkage assembly 130. The dynamic counterweight frame 160 is fixedly connected to the seat cushion support 132, and the counterweight 150 is disposed on the side of the dynamic counterweight frame 160 facing away from the seat frame linkage assembly 130. The dynamic counterweight frame 160 serves to assist in simulating the distribution of human body weight. In actual use, the weight distribution of the human body on the sofa changes with the sofa's posture. The dynamic counterweight frame 160 can better simulate this dynamic weight change, making the test results closer to real-world usage scenarios and improving the accuracy and reliability of the test.

[0037] The aforementioned electric sofa testing device 100 includes a control component 110, a drive component 120, a seat frame linkage component 130, and a counterweight component 150. One end of the drive component 120 is connected to the output end 116 of the control component 110, and the other end is driven to connect to the seat frame linkage component 130. The seat frame linkage component 130 includes a backrest support 131, a seat cushion support 132, and a leg support 133 that are rotatably connected in sequence. At least one counterweight component 150 is provided on the support surface of the backrest support 131, the seat cushion support 132, and the leg support 133 to simulate the load conditions of the human back, torso, and legs under different postures. The control component 110 can drive one or more of the backrest support 131, the seat cushion support 132, and the leg support 133 to rotate around the connection point through the drive component 120 to simulate the posture changes of the electric sofa. Compared to the single testing angle of existing testing devices, this application can flexibly simulate multiple angle switching in actual use, such as sitting posture, movie-watching posture, and zero-gravity posture, through the seat frame linkage component 130, making the test results closer to real-world usage. The aforementioned electric sofa testing device 100 can simulate multiple angle working conditions of the sofa, improving the accuracy and reliability of the test.

[0038] For example, as shown in Figure 3, the dynamic counterweight frame 160 includes a seat frame 161. The side of the seat frame 161 facing the seat frame linkage assembly 130 is provided with a first support frame 1611. The seat frame 161 is fixedly connected to the seat cushion support 132 through the first support frame 1611. At least one counterweight 150 is provided on the side of the seat frame 161 away from the seat cushion support 132.

[0039] Specifically, to improve the connection stability between the seat frame 161 and the seat cushion support 132, a first support frame 1611 is also provided between the seat frame 161 and the seat cushion support 132. Preferably, the first support frame 1611 may include a crossbeam and at least one vertical beam, one end of the vertical beam being fixedly connected to the crossbeam, and the other end being fixedly connected to the side edge of the seat frame 161 via a threaded shaft, a bushing, and a nut. In one specific embodiment of this application, there are two first support frames 1611, which are respectively disposed on opposite sides of the seat frame 161.

[0040] The side of the seat frame 161 facing away from the seat cushion support 132 is relatively flat, and at least one counterweight 150 is provided on its surface. This facilitates the placement of the counterweight 150 and improves the assembly reliability of the electric sofa testing device 100. The counterweight 150 is fixedly connected to the seat frame 161 by screws and sheet metal fixing.

[0041] As shown in Figure 3, in one specific embodiment of this application, the number of counterweights 150 provided on the seat frame 161 is three. The three counterweights 150 can be arranged sequentially on the seat frame 161 in a horizontal or vertical direction, so that the force on the seat frame 161 is more even.

[0042] For example, as shown in Figure 3, the dynamic counterweight frame 160 includes a backrest frame 162, the end of which is hinged to the seat frame 161; a first roller 1621 is provided on the side of the backrest frame 162 facing the seat linkage assembly 130, and the backrest frame 162 is slidably connected to the backrest support 131 through the first roller 1621; at least one counterweight 150 is provided on the side of the backrest frame 162 away from the backrest support 131.

[0043] Specifically, the backrest frame 162 and the seat frame 161 are connected by a hinge, allowing them to rotate relative to each other. When simulating changes in the posture of an electric sofa, such as switching from a sitting posture to a semi-reclining posture for watching a movie, the backrest support 131 tilts backward. At this time, the backrest frame 162 can rotate relative to the seat frame 161 around the hinge point, thereby synchronously adjusting its own posture and accurately simulating the angular changes of the human body in different postures.

[0044] When the backrest support 131 is tilted backward or forward under the action of the drive component 120, the first roller 1621 on the backrest frame 162 can roll along the surface of the backrest support 131, reducing the friction between the two. This arrangement not only allows the backrest frame 162 to move more smoothly with the backrest support 131, avoiding movement jamming or lag caused by frictional resistance, but also reduces component wear and extends the service life of the testing device.

[0045] The side of the backrest frame 162 facing away from the seat cushion support 132 is relatively flat, and at least one counterweight 150 is provided on its surface. This facilitates the placement of the counterweight 150 and improves the assembly reliability of the electric sofa testing device 100. The counterweight 150 is fixedly connected to the backrest frame 162 by screws and sheet metal fixing.

[0046] As shown in Figure 3, in one specific embodiment of this application, there are two counterweights 150 on the back frame 162. The two counterweights 150 are arranged vertically on the back frame 162. One counterweight 150 is located close to the position where the head is placed on the back frame 162, and the other counterweight 150 is located in the middle of the back frame 162.

[0047] For example, as shown in Figure 3, the dynamic counterweight frame 160 includes a leg frame 163, the end of which is hinged to the seat frame 161; a second roller 1631 is provided on the side of the leg frame 163 facing the seat linkage assembly 130, and the leg frame 163 is slidably connected to the leg support body 133 through the second roller 1631; at least one counterweight 150 is provided on the side of the leg frame 163 away from the leg support body 133.

[0048] Specifically, the leg support 163 and the seat support 161 are connected by a hinge, giving them relative rotational freedom. When simulating changes in the posture of an electric sofa, such as switching from a sitting posture to a zero-gravity posture, the leg support 133 is raised. At this time, the leg support 163 can rotate around the hinge point with the seat support 161, thereby accurately simulating the angular relationship between the human legs and torso in different postures.

[0049] When the leg support 133 is angled under the action of the drive component 120, such as when it is raised or lowered, the second roller 1631 on the leg frame 163 can roll along the surface of the leg support 133, effectively reducing the friction between the two. This not only allows the leg frame 163 to move more smoothly with the leg support 133, avoiding movement difficulties or jamming caused by frictional resistance, but also reduces wear between components and extends the service life of the testing device.

[0050] Furthermore, through this sliding connection method, the leg frame 163 can closely conform to the posture changes of the leg support 133 in real time. No matter what angle the leg support 133 is adjusted to, the leg frame 163 can adjust its position in a timely manner through the sliding of the second roller 1631, ensuring that the weight of the human leg simulated by the counterweight 150 on it always acts on the leg support 133 in the correct direction and force. This achieves accurate simulation of the force state of the electric sofa leg support under different usage scenarios, providing more reliable test data for a comprehensive evaluation of the electric sofa's performance.

[0051] The side of the leg frame 163 facing away from the seat cushion support 132 is relatively flat, and at least one counterweight 150 is provided on its surface, which facilitates the placement of the counterweight 150 and improves the assembly reliability of the electric sofa testing device 100. The counterweight 150 is fixedly connected to the back frame 162 by screws and fixing sheet metal.

[0052] As shown in Figure 3, in one specific embodiment of this application, the number of counterweights 150 provided on the leg frame 163 is one, and the counterweight 150 is located in the middle of the leg frame 163 so that the force on the leg frame 163 is more even.

[0053] In one possible embodiment of this application, as shown in Figures 2 and 4, the backrest support 131 is connected in sequence to a second support frame 1311 and a back support plate 1312 at the end away from the seat cushion support 132, and the second support frame 1311 and the back support plate 1312 are fixedly connected; the back frame 162 is slidably connected to the back support plate 1312 through a first roller 1621.

[0054] Specifically, as shown in Figures 2 and 4, to provide better support for the backrest frame 162 and ensure sufficient range of motion, a second support frame 1311 and a back support plate 1312 are provided at the end of the backrest support 131 away from the seat cushion support 132. One end of the second support frame 1311 is fixedly connected to the backrest support 131 by sheet metal and screws, and the surface of the other end is covered with the back support plate 1312. The back support plate 1312 provides a flat contact surface for the backrest frame 162. Preferably, the surface of the back support plate 1312 is provided with a wear-resistant coating to accommodate the requirements of a sliding connection.

[0055] In one possible embodiment of this application, as shown in Figures 2 and 4, the end of the leg support 133 away from the seat cushion support 132 is connected to a leg support plate 1331, and the leg frame 163 is slidably connected to the leg support plate 1331 via a second roller 1631.

[0056] Specifically, to provide better support for the backrest frame 162, as shown in Figures 2 and 4, a leg support plate 1331 is connected to the end of the leg support 133 away from the seat cushion support 132. The leg support plate 1331 is typically made of a high-strength, wear-resistant material, such as steel plate, thereby providing a flat and stable contact surface for the legrest frame 163, while also enhancing the structural strength of the end of the leg support 133 and preventing deformation due to stress concentration during testing.

[0057] Optionally, as shown in Figure 5, the control component 110 further includes a display module 113, which includes a digital display tube. The digital display tube is connected to the microcontroller 111, and the microcontroller 111 can display test information through the digital display tube. The digital display tube can count the data signals received after processing by the microcontroller 111, and display parameters related to the life test in real time through the display module 113, such as the cumulative number of power on / off cycles and the test duration. This allows testers to intuitively understand the test progress and equipment aging status, determine whether the equipment is faulty or has reached its expected lifespan, and improve test efficiency and reliability.

[0058] For example, as shown in Figure 5, the control component 110 also includes a plurality of push-button switches 114, which are electrically connected to the microcontroller 111. The push-button switches 114 can send control signals to the microcontroller 111 to start or stop the test and / or adjust the test parameters. The test parameters include the number of tests, the test posture change, and the driving frequency of the drive unit 120.

[0059] In one specific embodiment of this application, as shown in FIG5, there are four push-button switches 114. The four push-button switches 114 serve as input devices; pressing a push-button switch 114 generates an electrical signal, which is then sent to the microcontroller 111. The microcontroller 111 performs corresponding processing such as increasing, decreasing, or selecting the test time based on different button operations, thereby enabling adjustments to the test display mode and parameter settings.

[0060] The above description is merely an optional embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.

[0061] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.
