Description

Technical Field

[0001] This utility model specifically relates to a pressure feedback device for mattress production testing, belonging to the field of mattress production technology. Background Technology

[0002] A mattress is a piece of bedding designed to provide a comfortable sleep environment, typically placed on a bed frame. It consists of springs, foam, latex, memory foam, coir, or a combination of these materials, designed to provide adequate support and comfort to accommodate different body types and sleeping positions, ensuring a high-quality sleep experience and meeting diverse sleep needs and preferences. However, current mattress testing methods only detect the mattress's compression and rebound performance, failing to detect the bending forces exerted by the body on the mattress. They also cannot detect the pressure distribution under different bending conditions, making it difficult to assess the mattress's comfort and support performance, thus presenting certain drawbacks in the usage process.

[0003] In view of the above, this utility model is hereby proposed. Utility Model Content

[0008] Furthermore, in order to control the rotation of the bidirectional threaded rod so that the two threaded sliders can slide synchronously in opposite directions in the limiting groove, thereby adjusting the distance between the first limiting side plate and the second limiting side plate, there are two threaded sliders, which are respectively located at the opposite thread ends of the bidirectional threaded rod, and the first limiting side plate and the second limiting side plate are respectively fixed on the two threaded sliders.

[0009] Furthermore, in order to enable the lateral sliding connector to move via the extension and retraction of the lateral telescopic rod, the follow-type pin connection assembly includes the vertical mounting base, which is fixed to both ends of the top snap-fit ​​strip.

[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] Please see Figures 1-5 As shown, a pressure feedback device for mattress production testing includes a base 1. A limiting groove is formed on the top of the base 1, and a clamping and positioning component 2 is installed in the limiting groove. The clamping and positioning component 2 is used to clamp and position the mattress. A first limiting side plate 3 and a second limiting side plate 4 are installed on the clamping and positioning component 2. A transverse clearance groove is formed on the first limiting side plate 3 and the second limiting side plate 4, and a top locking strip 5 is slidably installed in the transverse clearance groove. The two ends of the top locking strip 5 are fixedly connected to the first limiting side plate 3 and the second limiting side plate 4 through a follow-type pin connecting component 6. A pressure sensing module 7 is fixedly installed on the top locking strip 5, and the pressure sensing module 7 is in close contact with the top of the mattress. A rotary end lifting component 8 is installed on the top locking strip 5, and the rotary end lifting component 8 is used to rotate and lift both ends of the mattress. In use, the mattress is placed on the base 1. On seat 1, the mattress is limited by the clamping and positioning component 2. When controlling the clamping and positioning component 2, the top locking strip 5 is separated from the first limiting side plate 3 and the second limiting side plate 4 by the following pin connecting component 6 to avoid affecting the positioning of the mattress. At the same time, the top locking strip 5 can slide laterally on the first limiting side plate 3 and the second limiting side plate 4 so that the pressure sensing module 7 can be located at different positions above the mattress. The top locking strip 5 can be fixedly connected to the first limiting side plate 3 and the second limiting side plate 4 by the following pin connecting component 6. After the position of the top locking strip 5 is determined, the rotating end lifting component 8 is controlled to lift the two ends of the mattress respectively, so that the two ends of the mattress are slightly raised. The pressure sensing module 7 realizes the force situation when the mattress is bent at different positions, so as to test the pressure feedback of the human body at different bending angles.

[0022] The clamping and positioning assembly 2 includes a servo motor 201 and a bidirectional threaded rod 202. The servo motor 201 is fixed to the inner wall of one end of the limiting slide groove. The bidirectional threaded rod 202 is rotatably mounted on the inner wall of the other end of the limiting slide groove via a rotating joint 203. One end of the bidirectional threaded rod 202 is fixedly connected to the output shaft of the servo motor 201. Threaded sliders 204 are mounted on the bidirectional threaded rod 202 and are slidably engaged in the limiting slide groove. There are two threaded sliders 204, located at the opposite thread ends of the bidirectional threaded rod 202. A first limiting side plate 3 and a second limiting side plate 4 are fixed to the two threaded sliders 204. In use, the servo motor 201 is started to drive the bidirectional threaded rod 202 to rotate. Because the bidirectional threaded rod 202 has opposite threads, the two threaded sliders 204 slide to the sides, causing the first limiting side plate 3 and the second limiting side plate 4 fixed to them to move, thereby achieving clamping and positioning of the mattress. By precisely controlling the rotation of the servo motor 201, the clamping force and position can be adjusted to ensure that the mattress remains stable during the testing process, thereby improving the accuracy and safety of the testing and making it suitable for testing mattresses of different sizes.

[0023] The follow-type pin connection assembly 6 includes a vertical mounting base 601, which is fixed to both ends of the top snap-fit ​​strip 5. A horizontal telescopic rod 602 is fixedly inserted into the vertical mounting base 601. A horizontal sliding connector 603 is fixedly connected to the telescopic end of the horizontal telescopic rod 602. A positioning pin 604 is slidably inserted into the horizontal sliding connector 603. One end of the positioning pin 604 is inserted into a positioning pin hole that is linearly opened at the top of the first limiting side plate 3 and the second limiting side plate 4. The other end of the positioning pin 604 is fixedly installed with a lifting device. The handle 605 is used to move the positioning pin 604 by pulling the handle 605, so that it can be inserted into or pulled out of the positioning pin hole on the first limiting side plate 3 and the second limiting side plate 4, thereby fixing or separating the top locking strip 5 from the first limiting side plate 3 and the second limiting side plate 4. At the same time, the telescopic function of the horizontal telescopic rod 602 can adjust the position of the horizontal moving connector 603, ensuring that the positioning pin 604 accurately aligns with the positioning pin hole of the first limiting side plate 3 and the second limiting side plate 4, thereby improving connection stability and ease of operation.

[0024] The rotary end lifting assembly 8 includes a drive motor 801, which is fixed at both ends of the top snap-fit ​​strip 5. A rotary drive rod 802 is fixedly connected to the output shaft of the drive motor 801. A swing telescopic rod 803 is fixedly sleeved on the rotary drive rod 802. There are two swing telescopic rods 803, which face the two sides of the base 1 respectively. A rotary lifting plate 804 is fixedly installed at the telescopic end of the swing telescopic rod 803. When in use, the drive motor 801 is started, and the swing telescopic rod 803 is rotated through the rotary drive rod 802. Adjust the telescopic length of the swing telescopic rod 803 so that the rotating lifting plate 804 fits the mattress. As the drive motor 801 continues to rotate, the rotating lifting plate 804 slightly lifts one end of the mattress to simulate the folding action in actual use. This facilitates the testing of the pressure distribution and support performance of the mattress at different angles. During use, the deformation of the mattress is slightly controlled to simulate a slight sinking when a person lies on it. The slight rising and falling of the rotating lifting plates 804 at both ends during operation does not affect the overall operation.
