Description

Technical Field

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

[0002] Currently, most car seats have a seat rotation function to meet user needs. The rotation function of car seats is achieved through a seat turntable, also known as a seat plate. The seat turntable consists of an upper plate and a lower plate. Generally, the lower plate is fixed, and the upper plate is fixed to the seat frame. The upper and lower plates can rotate relative to each other, thereby realizing the rotation of the seat.

[0003] After assembly, the existing seat tray needs to undergo performance testing. The main test is to check whether there are any abnormal noises or vibrations after the seat tray is powered on. If abnormal vibration occurs, it means that the upper plate is not effectively pressing the lower plate, which will cause the turntable to wobble significantly when the seat is rotated. The seat tray is therefore unqualified.

[0004] To improve the efficiency of seat performance testing, there is a need to provide a seat performance testing device. Utility Model Content

[0005] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a seat performance testing device to improve the efficiency of seat plate performance testing.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a seat performance testing device, including a soundproof room and an equipment bracket and a product conveyor line located inside it; the product conveyor line includes a conveyor belt for placing the seat to be tested and a mounting bracket located on its side and arranged along its conveying direction, the mounting bracket having a power pin on the side facing the conveyor belt, which can provide power to the seat placed on the conveyor belt, a pressure load connected to the equipment bracket through a load lifting mechanism, and the pressure load being located above the conveyor belt, the load lifting mechanism being able to drive the pressure load to move downward and place it completely on the seat, the pressure load being equipped with a vibration sensor and a sound collector.

[0007] Furthermore, the conveyor belt is supported by a support bracket below, and at least one guide column lifting cylinder is vertically arranged on the lower surface of the support bracket. A limiting guide column is fixed at the top of the piston rod of each guide column lifting cylinder.

[0008] Furthermore, the power connector is fixedly connected to the mounting bracket via a horizontally positioned telescopic cylinder.

[0009] Furthermore, the lower surface of the pressure load has a first end and a second end opposite to each other. The first end is provided with a limiting pad, and the second end is provided with a limiting block. Both the limiting pad and the limiting block are arranged along the conveying direction of the conveyor belt.

[0010] Furthermore, the bottom of the limiting block is provided with a limiting slot, which includes an arc-shaped surface and an inclined surface extending outward from both ends of the arc-shaped surface.

[0011] Furthermore, the load lifting mechanism includes a lifting bracket horizontally mounted on the upper part of the equipment support and a load driving cylinder vertically mounted on the lifting bracket. A lifting connecting plate is horizontally connected to the top of the piston rod of the load driving cylinder, and the four corners of the lifting connecting plate are respectively connected to the pressure load by connecting belts.

[0012] Furthermore, the lifting support is also equipped with a displacement adjustment component, which enables the pressure load to move back and forth along the conveyor belt conveying direction. The displacement adjustment component includes a fixed base plate and a cylinder support plate arranged parallel to each other. The fixed base plate is fixed on the upper surface of the lifting support. The load driving cylinder is vertically mounted on the cylinder support plate, and its drive shaft passes through the cylinder support plate. The bottom of the cylinder support plate is slidably connected to the fixed base plate through a sliding rail. The cylinder support plate also has a horizontally adjustable cylinder. The drive end of the adjustable cylinder is fixedly connected to the lifting support through a connecting block.

[0016] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0017] See appendix Figures 1 to 7 As shown in this embodiment, a seat performance testing device is used to detect whether the seat tray will produce abnormal noise or vibration during movement. It includes a soundproof room 1 and an equipment bracket 2 and a product conveyor line 9 located inside it. The product conveyor line 9 includes a conveyor belt 91 for placing the seat tray to be tested and a mounting bracket 92 located on its side and arranged along its conveying direction. A power pin 11 is provided on the side of the mounting bracket 92 facing the conveyor belt 91, which can provide power to the seat tray placed on the conveyor belt 91. A pressure load 3 is connected to the equipment bracket 2 through a load lifting mechanism 4, and the pressure load 3 is located above the conveyor belt 91. The load lifting mechanism 4 can drive the pressure load 3 to move downward and place it completely on the seat tray. A vibration sensor 5 and a sound collector 6 are provided on the pressure load 3. After the seat is placed on the conveyor belt 91, the load lifting mechanism 4 drives the pressure load 3 to move downward and press it completely onto the seat. The pressure load 3 is no longer subject to the traction force of the load lifting mechanism 4. At this time, the pressure load 3 can simulate the normal weight of the human body to ensure the accuracy of subsequent seat performance testing.

[0018] The lower plate of the base plate is provided with a connection socket that matches the power pin 11. After power is applied, the upper plate of the base plate can rotate relative to its lower plate. During the rotation, if abnormal noise or vibration occurs between the upper and lower plates, it can be immediately captured and sensed by the sound collector 6 or vibration sensor 5 set on the pressure load 3, which effectively improves the efficiency of base plate performance detection.

[0019] Specifically, the sound collector 6 can compare the collected sound with the preset decibel value on the external controller. If it is higher than the preset value, it proves that the upper plate is making abnormal noise during rotation, and the upper and lower plates are not properly installed. The vibration sensor 5 can sense the vibration generated during the rotation of the upper plate. If the sensed vibration frequency exceeds the preset frequency value on the external controller, it indicates that abnormal vibration is generated during the rotation of the upper plate, and the upper and lower plates are not properly assembled.

[0020] It should be noted that the ability of the upper plate of a car seat to rotate relative to the lower plate after being powered on is existing technology, and its specific principle will not be elaborated here.

[0021] During the testing process, the use of a soundproof room 1 can effectively prevent the noise generated during the test from affecting the external environment.

[0022] The conveyor belt 91 is supported by a support bracket. At least one guide column lifting cylinder 14 is vertically installed on the lower surface of the support bracket. A limiting guide column 13 is fixed to the top of the piston rod of each guide column lifting cylinder 14. The limiting guide column 13 can position the seat plate on the conveyor belt 91 to ensure that when the subsequent load lifting mechanism 4 drives the pressure load 3 to move downward, it can press against the seat plate. The center of gravity of the pressure load 3 is exactly on the same vertical line as the center of gravity of the seat plate. This ensures that the pressure or angle of the pressure load 3 is completely consistent with that of a person sitting on the seat plate, thereby ensuring the accuracy of subsequent seat plate performance testing.

[0023] In some embodiments, the conveyor belt 91 includes a plurality of parallel and spaced-apart drive rollers, and the limiting guide post 13 is disposed in the gap between two adjacent drive rollers, so that the drive rollers do not interfere with each other during the up and down movement of the limiting guide post 13.

[0024] Specifically, there are two limit guide posts 13. The seat plate is conveyed to the conveyor belt 91 via a conveyor belt perpendicular to the conveying direction of the conveyor belt 91. The piston rod of the guide post lifting cylinder 14 extends, driving the limit guide post 13 to move upward and pass through the positioning hole opened through the seat plate, thereby accurately positioning the lower plate of the seat plate. This ensures that the seat plate will not shift horizontally relative to the conveyor belt 91 during the performance test, thus ensuring the accuracy of subsequent seat plate performance testing.

[0025] The power pin 11 is fixedly connected to the mounting bracket 92 via a horizontally positioned telescopic cylinder 10. The telescopic cylinder 10 controls the insertion or removal of the power pin 11 into the base plate, thereby automatically powering the base plate and facilitating control of the rotation of the upper plate for testing or stopping.

[0026] The lower surface of the pressure load 3 has a first end and a second end. The first end is provided with a limiting pad 7, and the second end is provided with a limiting block 8. Both the limiting pad 7 and the limiting block 8 are arranged along the conveying direction of the conveyor belt 91. When the pressure load 3 presses against the seat plate, the limiting pad 7 abuts against the seat plate. The upper surface of the seat plate has a positioning groove that matches the shape of the limiting pad 7. When the pressure load 3 moves downward, the limiting pad 7 can be directly inserted into the positioning groove and guide the subsequent downward movement of the pressure load 3.

[0027] The bottom of the limiting block 8 is provided with a limiting slot 81, which includes an arc-shaped surface and an inclined surface extending outward from both ends of the arc-shaped surface. A columnar crossbar is provided at one end of the base plate away from the positioning groove. The limiting slot 81 on the limiting block 8 can precisely engage the columnar crossbar. The inclined surface guides the direction in which the columnar crossbar engages with the limiting slot 81, allowing the columnar crossbar to quickly engage with the limiting slot 81, thereby further limiting the horizontal displacement of the base plate.

[0028] The load lifting mechanism 4 includes a lifting bracket 41 horizontally mounted on the upper part of the equipment support 2 and a load driving cylinder 42 vertically mounted on the lifting bracket 41. A lifting connecting plate 43 is horizontally connected to the top of the piston rod of the load driving cylinder 42. The four corners of the lifting connecting plate 43 are connected to the pressure load 3 by connecting straps 44. When it is necessary to press the pressure load 3 down onto the base plate, the piston rod of the load driving cylinder 42 extends, driving the lifting connecting plate 43 to move downward until the pressure load 3 is pressed firmly onto the base plate.

[0029] The pressure load 3 is not directly fixedly connected to the load drive cylinder 42, so that the pressure load 3 will not be subjected to upward tension when it is pressed on the seat plate, thereby ensuring the accuracy of simulating a human body sitting on the seat plate and ensuring the accuracy of subsequent performance tests.

[0030] The lifting support 41 is also equipped with a displacement adjustment component 15, which enables the pressure load 3 to move back and forth along the conveying direction of the conveyor belt 91. The displacement adjustment component 15 includes a fixed base plate 151 arranged vertically and horizontally and a cylinder support plate 153. The fixed base plate 151 is fixed on the upper surface of the lifting support 41. The load driving cylinder 42 is vertically arranged on the cylinder support plate 153, and its drive shaft passes through the cylinder support plate 153. The bottom of the cylinder support plate 153 is slidably connected to the fixed base plate 151 through a sliding rail 152. There is also a horizontally adjustable cylinder 154 on the cylinder support plate 153. The drive end of the adjustable cylinder 154 is fixedly connected to the lifting support 41 through a connecting block. When it is necessary to adjust the position of the pressure load 3 along the conveyor belt 91, the piston rod of the adjusting cylinder 154 extends or retracts, driving the entire cylinder support plate 153 to move away from or towards the conveyor belt 91, so that the pressure load 3 can press down on the seat plate when it moves downward.

[0031] A distance sensor 12 is also provided on the side of the mounting bracket 92 facing the conveyor belt 91. The distance sensor 12 is used to sense the distance between the seat plate on the conveyor belt and the conveyor belt 91. When the seat plate is transferred from the conveyor belt to the conveyor belt 91, the distance sensor 12 senses and sends a distance signal to an external sensor. After receiving the signal, the external sensor controls the guide column lifting cylinder 14 to work, and the limiting guide column 13 extends and inserts into the seat plate to limit its position on the conveyor belt 91, so as to facilitate subsequent performance testing.

Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
