Description

Technical Field

[0001] This utility model relates to the technical field of mattress testing equipment, specifically a mattress testing device based on a falling ball impact test. Background Technology

[0002] A mattress is an item placed between the human body and a bed to ensure consumers get healthy and comfortable sleep. Mattresses are made of a variety of materials, and mattresses made of different materials can provide different sleep experiences. During the mattress manufacturing process, testing equipment is needed to test the resilience of the mattress foam. Traditional testing methods mostly use the falling ball rebound test.

[0003] In existing technologies, conventional mattress testing devices based on falling ball impact tests are difficult to accurately detect the degree of mattress rebound due to the lack of guidance in the direction of the falling ball's rebound. This results in inaccurate test results. Furthermore, mattress testing devices based on falling ball impact tests can only detect the mattress's rebound by falling balls alone, which is a limited testing method with poor practicality. Utility Model Content

[0004] This invention provides a mattress testing device based on a falling ball impact test to solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mattress testing device based on a falling ball impact test, comprising a battery box assembly. Rollers are fixedly mounted in a rectangular shape at the four corners of the lower surface of the battery box assembly. A lifting mechanism is fixedly mounted on the upper surface of the battery box assembly near the left side. A horizontal plate is fixedly mounted on the right side of the lifting mechanism. Two pressure sensors are fixedly mounted on the lower surface of the horizontal plate near the right edge, and a mounting plate is fixedly mounted between the lower surfaces of the pressure sensors. An electromagnetic chuck is fixedly mounted on the lower surface of the mounting plate. Vertical rods are mounted on the mounting plate near the left and right sides via a first mounting mechanism. A movable plate is mounted on the vertical rods near the lower side via a second mounting mechanism. A ball is fixedly mounted on the middle of the movable plate at a position corresponding to the electromagnetic chuck. A distance measuring sensor is provided on the lower surface of the mounting plate at a position corresponding to the upper surface of the movable plate.

[0006] Furthermore, the lifting mechanism includes a rectangular box, an electric linear module, a controller, and an operation display screen. The rectangular box is fixedly installed on the left edge of the upper surface of the electric heating box assembly. The right side of the rectangular box is an open structure. An electric linear module is provided between the upper and lower inner walls of the rectangular box, and the ball nut of the electric linear module is fixedly connected to the left side of the horizontal plate. The controller is installed on the left side of the rectangular box, and an operation display screen is embedded on the left side wall of the controller.

[0007] Furthermore, the controller is electrically connected to the battery box assembly, pressure sensor, electromagnetic chuck, and distance sensor, respectively.

[0008] Furthermore, the first mounting mechanism includes a first through hole and a locking bolt. The mounting plate has a first through hole at a position corresponding to the vertical rod, and the vertical rod is fixedly installed in the first through hole by the locking bolt.

[0009] Furthermore, the second mounting mechanism has the same structure as the first mounting mechanism.

[0010] Furthermore, each of the horizontal plates corresponding to the vertical rod is provided with a second through hole for the vertical rod to pass through.

[0011] Compared with the prior art, this utility model provides a mattress testing device based on a falling ball impact test, which has the following beneficial effects:

[0012] 1. This mattress testing device based on a falling ball impact test uses a vertical rod to move a ball up and down along the vertical rod via a moving plate. A distance sensor monitors the distance the vertical rod moves up and down, thus accurately detecting the rebound height of the ball and better detecting the degree of mattress rebound. When not in use, the ball on the moving plate can be easily fixed by a second mounting mechanism, making it convenient to use.

[0013] 2. This mattress testing device based on a falling ball impact test uses a first mounting mechanism to fix the vertical rod, and a second mounting mechanism to install the moving plate and ball on the lower edge of the vertical rod. The lifting mechanism moves the pressure sensor downward through the horizontal plate, and the pressure sensor moves the moving plate and ball downward through the mounting plate, allowing the moving plate and ball to press the mattress. This allows for prolonged and repeated pressing, increasing the mattress pressure detection function and enabling the detection of mattress stress and deformation. It is highly practical.

[0018] 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.

[0019] Please see Figures 1-3 This utility model discloses a mattress testing device based on a falling ball impact test, including a battery box assembly 1. Rollers 2 are fixedly installed in a rectangular shape at the four corners of the lower surface of the battery box assembly 1. A lifting mechanism 3 is fixedly installed on the upper surface of the battery box assembly 1 near the left side. A horizontal plate 4 is fixedly installed on the right side of the lifting mechanism 3. Two pressure sensors 5 are fixedly installed on the lower surface of the horizontal plate 4 near the right edge. A mounting plate 6 is fixedly installed between the lower surfaces of the pressure sensors 5. An electromagnetic chuck 7 is fixedly installed on the lower surface of the mounting plate 6. Vertical rods 9 are installed on the mounting plate 6 near the left and right sides via a first mounting mechanism 8. A movable plate 11 is installed on the vertical rods 9 near the lower side via a second mounting mechanism 10. A ball 12 is fixedly installed on the upper middle part of the movable plate 11, corresponding to the position of the electromagnetic chuck 7. A distance measuring sensor 13 is set on the lower surface of the mounting plate 6, corresponding to the position of the upper surface of the movable plate 11.

[0020] Specifically, the lifting mechanism 3 includes a rectangular box 301, an electric linear module 302, a controller 303, and an operation display screen 304. The rectangular box 301 is fixedly installed on the left edge of the upper surface of the electric heating box assembly. The right side of the rectangular box 301 is an open structure. The electric linear module 302 is arranged between the upper and lower inner walls of the rectangular box 301, and the ball nut of the electric linear module 302 is fixedly connected to the left side of the horizontal plate 4. The controller 303 is installed on the left side of the rectangular box 301, and the operation display screen 304 is embedded in the left side wall of the controller 303.

[0021] In this embodiment, the operation display screen 304 causes the ball screw in the electric linear module 302 to rotate in the upper and lower bearing assemblies through the controller 303. The ball screw drives the ball nut to move up and down along the inner wall of the rectangular box 301, and the ball nut drives the horizontal plate 4 to move up and down, thereby achieving the effect of adjusting the height of the ball 12.

[0022] Specifically, the controller 303 is electrically connected to the battery box assembly 1, the pressure sensor 5, the electromagnetic chuck 7, and the distance sensor 13, respectively.

[0023] In this embodiment, the battery in the battery box assembly 1 provides power to the controller 303. The controller 303 can control the opening and closing of the pressure sensor 5, the electromagnetic chuck 7 and the distance sensor 13, and receive the detected information.

[0024] Specifically, the first mounting mechanism 8 includes a first through hole 801 and a locking bolt 802. The mounting plate 6 has a first through hole 801 at a position corresponding to the vertical rod 9, and the vertical rod 9 is fixedly installed in the first through hole 801 by the locking bolt 802.

[0025] In this embodiment, the first through hole 801 is used for the installation of the vertical rod 9, and the locking bolt 802 locks and fixes the vertical rod 9 to the mounting plate 6, thereby achieving the effect of fixing the vertical rod 9.

[0026] Specifically, the second mounting mechanism 10 has the same structure as the first mounting mechanism 8.

[0027] In this embodiment, the second installation mechanism 10 can lock and fix the movable plate 11 to the vertical rod 9.

[0028] Specifically, each of the horizontal plates 4 corresponding to the vertical rod 9 is provided with a second through hole 14 for the vertical rod 9 to pass through.

[0029] In this embodiment, the second through hole 14 meets the requirements for the vertical rod 9 to move up and down and be limited on the horizontal plate 4.

[0030] In use, the battery box assembly 1 is moved to the underside of the mattress and locked via the braked roller 2. The operation display screen 304 in the lifting mechanism 3, via the controller 303, causes the ball screw in the electric linear module 302 to rotate in the upper and lower bearing assemblies. This causes the ball screw to move the ball nut up and down along the inner wall of the rectangular box 301. The ball nut then moves the horizontal plate 4 up and down. The horizontal plate 4, via the pressure sensor 5, moves the mounting plate 6 up and down. The mounting plate 6 then moves the electromagnetic chuck 7 up and down, thus adjusting the height of the ball 12. Next, the locking bolt 802 in the first mounting mechanism 8 is loosened, and the vertical rod 9 moves downward within the mounting plate 6, ensuring a suitable distance between the lower surface of the vertical rod 9 and the upper surface of the mattress. The locking bolt 802 is then used to lock the vertical rod 9 into the first through hole 801 on the mounting plate 6. Based on the positions of the left and right vertical rods 9, the impact point on the mattress is determined. The second mounting mechanism 10 is then loosened, and the controller 303 opens the electromagnetic chuck 7, attracting the ball 12 to the lower surface of the electromagnetic chuck 7. 3. The electromagnetic chuck 7 is closed. The ball 12 impacts the mattress along the vertical rod 9 via the moving plate 11. After impacting the mattress, the ball 12 bounces upward along the vertical rod 9. The distance of the upward bounce of the moving plate 11 is detected by the distance sensor 13, which is the height of the upward rebound of the ball 12. This allows for better detection of the mattress's rebound degree. When it is necessary to press the mattress, the ball 12 on the moving plate 11 is installed at the lower edge of the vertical rod 9 via the second mounting mechanism 10. The lifting mechanism 3 drives the pressure sensor 5 downward via the horizontal plate 4. The pressure sensor 5 drives the moving plate 11 and the ball 12 on the vertical rod 9 downward via the mounting plate 6, allowing the moving plate 11 and the ball 12 to press the mattress. This allows for long-term and repeated pressing. The pressure sensor 5 feeds back the pressure information to the controller 303 and displays it on the operation display screen 304. This adds a mattress pressing detection function, enabling the detection of the mattress's stress and deformation, making it highly practical.

[0031] In summary, this mattress testing device based on the falling ball impact test can accurately detect the rebound height of the ball 12, better detect the degree of mattress rebound, and easily fix the ball 12 when not in use. It also adds pressure detection of the mattress, thereby detecting the stress and deformation of the mattress, making it highly practical.

[0032] 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.
