Description

Technical Field

[0001] This utility model relates to the field of seat testing technology, and in particular to a seat testing device. Background Technology

[0002] With the continuous development of the automotive industry, car seats, as an important component of the vehicle interior, directly affect passenger comfort and safety in terms of performance and quality. Therefore, rigorous laboratory testing of car seats has become essential.

[0003] Automotive seat testing laboratories are typically equipped with advanced testing equipment capable of simulating various real-world usage conditions to conduct durability tests on different components of the seat. Among these, the backrest side wing compression durability test, simulated knee pressure test, and backrest frame assembly durability test are key tests for evaluating seat reliability and performance. The backrest side wing compression durability test primarily targets the side wing portion of the seat back, simulating the compression and friction exerted on the wing by passengers during prolonged use. By repeatedly applying and releasing pressure, the durability of the side wing material and structure is tested to ensure that deformation or damage does not occur after long-term use.

[0004] The simulated knee pressure test focuses on evaluating the seat's performance under repeated pressure from a passenger's knee. This test simulates the pressure of a passenger's knee on the front edge of the seat when getting on and off the vehicle or sitting for extended periods, examining the wear resistance of the seat materials and the stability of the seat structure. The backrest frame assembly durability test is a comprehensive test of the overall structural strength of the seat back. By simulating loads and stresses under various usage scenarios, it tests the fatigue resistance of the backrest frame, ensuring that structural failure will not occur under extreme conditions and long-term use.

[0005] In existing technologies, when testing car seats, separate components are used to conduct backrest and side wing compression tests on the car seats. That is, when the car seat is tested for side wing compression, a separate compression component is required for durability testing; when the car seat is tested for backrest, another separate set of components is required for durability testing of the car seat backrest. However, in the above solutions, the components need to be configured separately, which increases the floor space. At the same time, the car seat test requires switching between different test components, which greatly increases the preparation time during the test process, resulting in a decrease in overall test efficiency.

[0006] Therefore, this application aims to solve the problem that when testing automotive seats, the use of separate components for side wing compression and backrest results in a large footprint and low efficiency when switching between test components. Utility Model Content

[0007] The main purpose of this invention is to provide a seat testing device that optimizes the structure of automotive seat testing components, further reduces the space occupied, and improves the switching efficiency of automotive seats in side wing compression tests and backrest tests.

[0008] To achieve the above objectives, this utility model proposes a seat testing device, comprising:

[0009] support;

[0010] A movable frame is connected to and can be raised and lowered on the support;

[0011] The adjustment mechanism, slidably mounted on the movable frame, includes:

[0012] The movable plate is slidably connected to the movable frame;

[0013] The second telescopic component is connected to the movable plate;

[0014] The pressure member is connected to the output end of the second telescopic member;

[0015] The connection between the movable frame and the support rotates, causing the pressure member to switch between horizontal and vertical ranges.

[0016] Furthermore, the adjustment mechanism includes a fixed plate, which is connected to the first end of the second telescopic member away from the pressure member, and the fixed plate is connected to the movable plate.

[0017] Furthermore, the output end of the second telescopic member is detachably connected to the pressure member.

[0018] Furthermore, a first telescopic component is installed on the movable frame, and the output end of the first telescopic component is connected to the movable plate, driving the movable plate to move along the trajectory of the movable frame.

[0019] Furthermore, the support includes a horizontal frame and vertical frames connected to both ends of the horizontal frame.

[0020] Furthermore, one or two of the vertical frames are provided with a lifting mechanism, which is connected to the movable frame and drives the movable frame to move along the height direction of the vertical frame.

[0021] Furthermore, the lifting mechanism includes a screw placed on the vertical frame, and a slider threaded onto the screw, the slider being rotatably connected to the movable frame.

[0022] Furthermore, one end of the screw is connected to an adjusting member, which is connected to the vertical frame.

[0023] The above technical solution has the following advantages:

[0024] This utility model employs a bracket, a movable frame, and an adjustment mechanism. The adjustment mechanism uses a second telescopic component to drive the pressure component to apply pressure multiple times toward the car seat, thereby achieving multiple fatigue strength tests on the side wings of the car seat. When a backrest fatigue test is required, the movable frame is rotated, causing the pressure component to rotate and face the seat back, allowing for subsequent fatigue testing of the seat. This angle can be adjusted as needed. Only a single component needs to be switched to test the seat back and side wings, saving personnel setup time and test cycle time. At the same time, one piece of equipment can be used to meet other test operations, greatly improving space utilization and increasing the efficiency of switching tests, thus achieving cost reduction and efficiency improvement.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0032] like Figures 1-4As shown, a seat testing device includes a support 1, a movable frame 2, and an adjustment mechanism 4. The movable frame 2 is connected to and lifts and lowers on the support 1. The adjustment mechanism 4 is slidably placed on the movable frame 2 and includes a movable plate 44, a second telescopic member 43, and a pressing member 5. The movable plate 44 is slidably connected to the movable frame 2. The second telescopic member 43 is connected to the movable plate 44. The pressing member 5 is connected to the output end of the second telescopic member 43. The connection between the movable frame 2 and the support 1 rotates, causing the pressing member 5 to switch between horizontal and vertical ranges. The car seat is positioned below the adjustment mechanism 4. The moving frame 2 is vertically raised and lowered on the support 1, causing the adjustment mechanism 4 to move closer to or away from the car seat. The adjustment mechanism 4 causes the pressing component 5 to press against the seat back, thus conducting multiple fatigue tests on the car seat back. When it is necessary to press against the seat back, simply rotate the moving frame 2 along its connection with the support 1, such as rotating it 90°. This value can be freely switched. When the pressing component 5 is in a horizontal state, it can be moved towards the seat back via the second telescopic component 43 to conduct subsequent backrest fatigue tests. The whole process is simple, requiring only the switching of a single component to test the seat back and side wings, saving personnel setup time and test cycle time. At the same time, saving one piece of equipment can meet other test operations, greatly improving space utilization and increasing the efficiency of switching tests, thus achieving cost reduction and efficiency improvement.

[0033] like Figure 1 and Figure 2 As shown, the adjusting mechanism 4 includes a fixed plate 42, which is connected to the first end of the second telescopic member 43 away from the pressure member 5. The fixed plate 42 is connected to the movable plate 44. The fixed plate 42 and the movable plate 44 are fixed to each other by several guide columns, so that the fixed plate 42 and the movable plate 44 can move synchronously, ensuring that the connection of the second telescopic member 43 is stable in the working state. At the same time, the fixed plate 42 can prevent one end of the second telescopic member 43 from touching the top of the bracket 1. A stop switch can be installed on the fixed plate 42 to ensure that the second telescopic member 43 maintains a safe distance from the bracket 1.

[0034] like Figure 2 As shown, the output end of the second telescopic member 43 is detachably connected to the pressure member 5. The second telescopic member 43 can be fixed to the pressure member 5 by bolts or by clips. The pressure member 5 can be replaced at any time, and different pressure members 5 can be replaced according to the test requirements of the seat, such as using a pressure block with an arc-shaped head, an airbag, or a ball head, to meet the different fatigue test requirements of the car seat.

[0035] like Figure 2As shown, a first telescopic member 41 is installed on the movable frame 2. The output end of the first telescopic member 41 is connected to the movable plate 44, which drives the movable plate 44 to move along the trajectory of the movable frame 2. The output end of the first telescopic member 41 is connected to the movable plate 44 and drives the movable plate 44 to move back and forth along the length of the movable frame 2, which is convenient for adjustment according to the position of the seat.

[0036] The support 1 includes a horizontal frame 11 and vertical frames 12 connected to both ends of the horizontal frame 11, making the support 1 in an inverted U shape. The horizontal frame 11 is used to connect the vertical frames 12 at both ends, and the vertical frames 12 provide support for the entire horizontal frame 11.

[0037] like Figure 2 As shown, one or two vertical frames 12 are provided with lifting mechanisms 3. The lifting mechanisms 3 are connected to the movable frame 2 and drive the movable frame 2 to move along the height direction of the vertical frame 12. One or two lifting mechanisms 3 can be used. In this application, it is preferred to provide lifting mechanisms 3 on both vertical frames 12 to ensure the lifting stability of the movable frame 2.

[0038] like Figure 2 As shown, specifically, the lifting mechanism 3 includes a screw 31 placed on the vertical frame 12. A slider 32 is threaded onto the screw 31 and rotatably connected to the movable frame 2. One end of the screw 31 is connected to an adjusting member 33, which is connected to the vertical frame 12. The adjusting member 33 can drive the screw 31 to rotate, driving the slider 32 to move back and forth along the height direction of the vertical frame 12, thereby enabling the movable frame 2 to achieve height adjustment. A separate motor can be installed on the slider 32 to drive the movable frame 2 to achieve rotational adjustment, facilitating precise adjustment of the rotation angle of the pressure member 5. The adjusting member 33 can be driven by a handwheel or by a combination of a motor and a reducer; the specific method is not unique.

[0039] When a single lifting mechanism 3 is used, one of the vertical rods is driven by the aforementioned screw 31 and slider 32, while the slider 32 on the other vertical rod slides along its height direction, together driving the two ends of the moving frame 2 to achieve height adjustment.

[0040] In addition, the lifting mechanism 3 can also be made of pneumatic cylinders, hydraulic cylinders and linear motors, etc. The first telescopic component 41 can be made of pneumatic cylinders, electric cylinders and hydraulic cylinders, which will not be described here.

[0041] The experimental process as part of this application is as follows:

[0042] Apply pressure to the center point of the seat's distribution area using a prosthetic knee (with a ball head of 100mm in diameter), hold for several seconds, then unload, and return the prosthetic knee to its initial position. Repeat this 3000 times for each center point. Seat cushion loading point division: A rectangle composed of dimensions A and B is symmetrical about the seat's symmetry plane. The rectangle is evenly distributed across the seat cushion surface. Points 1 and 2 are positioned on a straight line: When the backrest is adjusted to the designed angle, the ball head can apply pressure normally, and the distance between the ball head and the backrest is minimal, the straight line position of points 1 and 2 is defined by the projection of the ball's center onto the seat cushion surface.

[0043] After the test, the fabric should not be torn, and there should be no protrusions or serious dents. The electrical components located on the seat cushion (such as seat belt alarm sensors, occupant identification system (OCS) system, heating pad, ventilation system, etc.) should function normally.

[0044] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
