Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of massage waist support test equipment, in particular to a massage waist support load test system equipment. BACKGROUND

[0002] Massage waist support is a physiotherapy device designed based on human engineering mechanics and traditional Chinese medicine meridian theory, usually installed on the back of the car seat or office chair, providing support, massage and hot compress functions for the waist through built-in airbags, electric motors, rollers and other devices.

[0003] The inflatable massage waist support is a device that inflates the air bag through the air pump and uses the expansion and contraction of the air bag to support and massage the waist. Its core working principle is that the air bag expands to exert pressure on the waist after inflation, and contracts after deflation, thereby simulating the massage method of a masseur to knead and press the muscles of the waist, achieving the effect of relaxing muscles and promoting blood circulation. After the manufacture of the massage waist support, the waist support body, side wings and massage load need to be tested. Currently, the operator needs to manually install the sample, connect the test equipment, set the test parameters, and then observe and record all test indicators throughout the process. The traditional manual testing mode is extremely inefficient because each test needs to be carried out one by one and multiple project tests cannot be carried out simultaneously, resulting in a long test period. At the same time, manual operation also has human errors such as inaccurate test intensity control and incorrect data recording, which affect the accuracy of the test results.

[0004] Therefore, the technical personnel in the field are committed to developing a massage waist support load test system equipment to facilitate rapid testing of the massage waist support and improve the testing efficiency of the massage waist support. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a massage waist support load test system equipment to facilitate rapid testing of the massage waist support and improve the testing efficiency of the massage waist support. The technical solution of the present application to solve the above technical problem is as follows: A massage waist support load test system equipment, characterized by comprising A positioning assembly installed in a test box; A pressing assembly installed in the test box and located on the upper side of the positioning assembly for pressing the air bag placed on the positioning assembly, the pressing assembly being connected with a control assembly; A side wing test assembly installed in the test box, and the side wing test assembly being connected with a traction assembly, the traction assembly being connected with the control assembly.

[0006] The beneficial effects of the above scheme are: by setting the positioning assembly, the extrusion assembly, the side wing test assembly, the traction assembly and the control assembly, the automatic test integration of each part of the massage waist support is realized, the operator no longer needs to repeatedly install the sample, connect the test equipment, set the test parameters and observe and record each test index throughout the process, the test efficiency is greatly improved, and the test period is shortened. The control assembly can accurately control the pressure applied by the extrusion assembly on the air bag and the force of the traction assembly on the side wing test assembly, thereby avoiding the problem of inaccurate test force in manual operation, improving the accuracy of the test result, and the connection of each component with the control assembly is beneficial to accurate collection and recording of test data, reducing the possibility of manual data recording error.

[0007] On the basis of the above technical scheme, the application can also be improved as follows.

[0008] Further, the positioning assembly comprises a first positioning bottom plate and a second positioning bottom plate, the first positioning bottom plate is installed on the operation table, and the first positioning bottom plate is provided with a first positioning sheet metal; The second positioning bottom plate is installed on the sliding assembly, and the second positioning bottom plate is provided with a second positioning sheet metal.

[0009] The beneficial effects of the above further scheme are: by the first positioning sheet metal and the second positioning sheet metal, different components of the waist support can be quickly fixed, and subsequent rapid detection test is facilitated.

[0010] Further, the sliding assembly comprises a sliding rail installed on the operation table, a sliding block matched with the sliding rail is installed at the lower end of the second positioning bottom plate, the end of the second positioning bottom plate is connected with the output end of a driving cylinder, and the driving cylinder is installed on the lower side of the operation table.

[0011] The beneficial effects of the above further scheme are: the sliding assembly adopts the structure of the sliding rail, the sliding block and the driving cylinder, so that the second positioning bottom plate can move stably and accurately along the sliding rail Further, the extrusion assembly comprises an extrusion box, the extrusion box is provided with an extrusion plate at the bottom, and an extrusion cylinder is connected to the upper end of the extrusion box. A first measuring weight is further installed in the extrusion box.

[0012] The beneficial effects of the above further scheme are: during the test process, the upper and lower sides of the extrusion cylinder piston are in communication with the external atmosphere, so that the extrusion box extrudes the massage air bag under the gravity of the first measuring weight, and the extrusion cylinder is used to lift the extrusion box after the test is completed. Only the first measuring weight and the extrusion box are used to extrude and test the massage air bag, so that the extrusion force used for each test is consistent.

[0013] Furthermore, the control component includes a controller, which is connected to an air supply component and an air pipe mounting plate. The air pipe mounting plate is equipped with multiple air pipes that are respectively connected to the air bag and the side wings.

[0014] The beneficial effects of adopting the above-mentioned further solution are: the controller regulates the air supply component to supply air to the air bag and side wings through the air pipe, realizing the inflation, deflation and pressure control of the air bag and side wings. The centralized air supply and control method ensures that the air bag and side wings are synchronized and precisely controlled, improves test coordination and efficiency, and ensures a smooth test process and accurate results. Furthermore, the wing test assembly includes a wing pressure plate, a sliding column is connected to the lower side of the wing pressure plate, and the traction assembly is connected to the lower side of the sliding column.

[0015] The beneficial effects of adopting the above-mentioned further solution are: the traction component can drive the side wing pressure plate and sliding column to move, realize the stretching and compression test of the side wing of the massage waist support, simulate the actual force and movement of the side wing, comprehensively evaluate the performance and quality of the side wing, provide a complete test solution for the overall test of the massage waist support, and ensure that the side wing function is stable and reliable in actual use.

[0016] Furthermore, the traction assembly includes a traction plate, the upper end of which is connected to the sliding column, and the lower end of which is connected to a traction box, wherein a second measuring weight is installed inside the traction box; The traction plate is also connected to a traction cylinder.

[0017] The beneficial effects of adopting the above-mentioned further scheme are: the traction plate connects the sliding column and the traction box, the second measuring weight in the traction box measures the traction weight, the traction cylinder and the second measuring weight provide stable traction power, so that the traction assembly can apply precise traction force to the side wing test assembly, simulate the actual use of traction force or pressure, and improve the accuracy and reliability of the test.

[0018] Furthermore, a guide post is connected to the upper end of the extrusion box, and a guide sleeve is provided outside the guide post. The guide sleeve is installed on the mounting plate, and the mounting plate is located inside the test box.

[0019] The beneficial effects of adopting the above-mentioned further solution are: the guide column and the guide sleeve cooperate to provide stable guidance for the extrusion assembly, ensure its vertical lifting and lowering, prevent deviation and jamming, ensure that the extrusion cylinder smoothly pushes the extrusion box and extrusion plate to apply pressure to the air bag, improve the stability and reliability of the extrusion assembly, extend the service life of the equipment, and ensure that the test is carried out smoothly.

[0020] Furthermore, the lower end of the extrusion cylinder is open, and a piston is installed inside the extrusion cylinder. The lower end of the piston is connected to the extrusion box via a connecting rod. The upper end of the extrusion cylinder has an air intake pipe, and the end of the air intake pipe is connected to a first flared pipe. The first flared pipe is also connected to an air extraction device. A damping sliding block is installed inside the air intake pipe. The damping sliding block is provided with a vent hole. A fixing plate is installed inside the first flared pipe. The fixing plate has a vent channel. The fixing plate and the damping sliding block are connected by a spring. The extrusion cylinder also has a connecting pipe, which is arranged opposite to the suction pipe. A second flared pipe is connected to the end of the connecting pipe. A sealing ball is provided inside the second flared pipe. The sealing ball is connected to the damping sliding block through a connecting rod, and the length of the connecting rod is greater than the width of the extrusion cylinder.

[0021] The beneficial effects of adopting the above-mentioned further solution are: after the extrusion test, the extrusion box needs to be lifted slowly to avoid excessive pressure changes inside the massage air bag, which could damage the valve body and sensitive detection elements in the controller. At the same time, the feedback delay of the cylinder system in force and position control will affect its control accuracy, making it difficult for the cylinder to accurately control the force and position during the extrusion process, thus making it impossible to achieve precision extrusion.

[0022] In this application, when gas is passed into the first flared tube, the vent on the damping sliding block has a certain blocking effect on the compressed gas, causing the damping sliding block to slide to the left under the action of spring force and gas pressure, so that the sealing ball moves away from the end of the connecting tube, and the connecting tube is connected to the external gas, thereby causing the extrusion box to move down and extrude the air bag, forming an impact force to simulate the instantaneous force on the massage air bag. Moreover, the upper end of the extrusion cylinder is connected to the atmosphere, so that the extrusion force exerted by the extrusion box on the massage air bag is constant during subsequent stability tests.

[0023] After the test, the air extraction device extracts air. Because the vent on the damping sliding block blocks the gas, when the air extraction device extracts the gas from the first flared tube, the damping sliding block moves to the right and overcomes the spring force, causing the sealing ball to move to the left and block the connecting pipe. A vacuum gradually appears at the top of the squeezing cylinder, causing the squeezing box to slowly and gradually move upward, reducing the damage to the valve body and sensitive detection elements in the controller caused by the rapid pressure reduction change in the massage air bag.

[0026] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

Therefore, they should not be construed as limitations on this invention.

[0028] In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, a massage lumbar support load testing system device includes... Positioning component 1 is installed inside test chamber 2. Positioning component 1 is mainly used to fix the massage lumbar support in place so that it can maintain a stable position and posture during subsequent testing operations.

[0031] The extrusion assembly 3 is installed inside the test chamber 2 and located above the positioning assembly 1. It is used to extrude the air bag placed on the positioning assembly 1 to simulate the pressure that the massage waist support is subjected to during actual use, and thus test its performance. The extrusion assembly 3 is connected to the control assembly 4. Side wing test assembly 5 is installed inside test box 2 for testing the side wings of air bag, and side wing test assembly 5 is connected to traction assembly 6, which is connected to control assembly 4.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the positioning component 1 includes a first positioning base plate 7 and a second positioning base plate 8. The first positioning base plate 7 is mounted on the operating table 13, and a first positioning sheet metal 9 is mounted on the first positioning base plate 7. A magnetic suction component is mounted on the first positioning sheet metal 9, which can be used to position and fix the corresponding parts of the massage lumbar support. The second positioning base plate 8 is mounted on the sliding component, and a second positioning sheet metal 10 is mounted on the second positioning base plate 8. A magnetic suction component is also mounted on the second positioning sheet metal 10, which can be used to position and fix the corresponding parts of the massage lumbar support.

[0033] like Figure 2 and Figure 3 In another embodiment, the sliding assembly includes a slide rail 11 mounted on the operating table 13, a slider that cooperates with the slide rail 11 is mounted on the lower end of the second positioning base plate 8, and the end of the second positioning base plate 8 is connected to the output end of the drive cylinder 12. The drive cylinder 12 is mounted on the lower side of the operating table 13, so that the second positioning base plate 8 can move smoothly and accurately along the slide rail 11 under the drive of the drive cylinder 12, thereby driving the second positioning sheet metal 10 mounted thereon to move, which is beneficial for subsequent extrusion testing.

[0034] In this embodiment, the extrusion assembly 3 includes an extrusion box 14 with an extrusion plate at its bottom and an extrusion cylinder 15 connected to its upper end. A first measuring weight is also installed inside the extrusion box 14. When the air bag needs to be extruded, the control valve operates to allow both the upper and lower sides of the piston of the extrusion cylinder 15 to communicate with the external atmosphere. Under the influence of gravity, the first measuring weight moves the extrusion box 14 and the extrusion plate downwards, applying pressure to the air bag below. To achieve precise pressure control, the first measuring weight is installed inside the extrusion box 14. The air bag is massaged by the gravity of the first measuring weight, while the extrusion cylinder 15 is only used to lift the extrusion box 14. This allows for precise measurement and application of the required pressure, enabling the extrusion assembly 3 to apply precise pressure to the air bag according to relevant standards and requirements. This simulates various real-world pressure environments such as rapid extrusion, inflation, and deflation, thereby improving the realism of the test simulation and the reliability of the results.

[0035] The upper end of the extrusion chamber 14 is also connected to a guide column 24, and a guide sleeve 25 is provided outside the guide column 24. The guide sleeve 25 is installed on the mounting plate 20, which is located inside the test chamber 2. The cooperation between the guide column 24 and the guide sleeve 25 provides a stable guiding effect for the extrusion assembly 3, ensuring that the extrusion chamber 14 can maintain vertical movement during the lifting process and avoid deviation or jamming. This ensures that the extrusion cylinder 15 can smoothly push the extrusion chamber 14 and the extrusion plate to apply pressure to the air bag, effectively improving the stability and reliability of the extrusion assembly 3, extending the service life of the equipment, and ensuring that the entire testing process can proceed smoothly.

[0036] like Figure 2 In some embodiments, the control component 4 includes a controller 16, which is connected to an air supply component and an air pipe mounting plate 17. The air pipe mounting plate 17 is equipped with multiple air pipes that are respectively connected to the air bag and the side wings. As the core control unit of the entire testing system, the controller 16 can regulate the air supply component to supply air to the air bag and the side wings through the air pipes according to the preset test program and parameters, so as to realize the inflation, deflation and pressure control of the air bag and the side wings. This centralized air supply and control method can ensure that the air bag and the side wings are synchronously and accurately controlled during the test, thereby improving the coordination and efficiency of the test, ensuring the smooth progress of the test process and the accuracy of the test results.

[0037] In some embodiments, the side wing testing component 5 is mainly used to test the side wing portion of the massage lumbar support, including stretching and compression operations, to evaluate the performance and quality of the side wing in actual use. The side wing testing component 5 includes a side wing pressure plate 18, a sliding column 19 connected to the lower side of the side wing pressure plate 18, and a traction component 6 connected to the lower side of the sliding column 19. When the side wing needs to be tested, the control component 4 controls the traction component 6 to move, thereby causing the side wing pressure plate 18 and the sliding column 19 to move accordingly, thus realizing the compression test of the massage lumbar support side wing. This simulates various forces and movements experienced by the side wing during actual use, comprehensively evaluating the performance and quality of the side wing, providing a complete test scheme for the overall testing of the massage lumbar support, and ensuring the stability and reliability of the side wing function in actual use.

[0038] The traction assembly 6 includes a traction plate 21, the upper end of which is connected to a sliding column 19, and the lower end of which is connected to a traction box 22. A second measuring weight is installed inside the traction box 22. The traction plate 21 is also connected to a traction cylinder 23. When working, the traction cylinder 23 can provide stable traction power to the traction assembly 6. Under the combined action of the traction cylinder 23 and the second measuring weight, the traction assembly 6 can apply precise traction force to the side wing test assembly 5, thereby simulating the traction force or pressure situation in real use, improving the accuracy and reliability of the test, and ensuring the validity and credibility of the test results of the massage waist support side wing.

[0039] like Figure 4 As shown, in other embodiments, the lower end of the extrusion cylinder 15 is open, and a piston 26 is provided inside the extrusion cylinder 15. The lower end of the piston 26 is connected to the extrusion box 14 through a connecting rod. The upper end of the extrusion cylinder 15 has an air intake pipe 27. The end of the air intake pipe 27 is connected to a first flared pipe 28. The first flared pipe 28 is also connected to an air extraction device. A damping sliding block 29 is installed inside the air intake pipe 27. The damping sliding block 29 is provided with a vent hole, which can produce a damping effect on the gas flow. A fixing plate 30 is installed inside the first flared tube 28. The fixing plate 30 has a ventilation channel. The fixing plate 30 and the damping sliding block 29 are connected by a spring 31. The extrusion cylinder 15 also has a connecting tube 32. The connecting tube 32 is arranged opposite to the suction tube 27. The end of the connecting tube 32 is connected to a second flared tube 33. A sealing ball 34 is installed inside the second flared tube 33. The sealing ball 34 and the damping sliding block 29 are connected by a connecting rod 35. The length of the connecting rod 35 is greater than the width of the extrusion cylinder 15.

[0040] In this embodiment, when gas is introduced into the first flared pipe 28, the gas flow speed is slowed down due to the obstruction of the vent hole of the damping sliding block 29. Under the combined action of the spring 31 and the gas pressure, the damping sliding block 29 slides to the left, causing the sealing ball 34 to move to the right, thus connecting the connecting pipe 32 with the external gas. At this time, the compression box 14 moves down quickly to impact and compress the massage air bag. In the subsequent stability test, the upper end of the cylinder is connected to the atmosphere to ensure that the compression force of the compression box 14 on the air bag remains constant. After the test, the air extraction device is activated. Due to the obstruction of the vent hole of the damping sliding block 29, the damping sliding block 29 moves to the right to overcome the spring force, and the sealing ball 34 moves to the left to block the connecting pipe 32. A vacuum is gradually formed at the upper end of the compression cylinder 15, and the compression box 14 moves up slowly, effectively reducing the damage to the valve body and detection sensitive elements inside the controller caused by the sudden pressure drop inside the air bag.
