A load device for detecting the performance of a massage chair movement

Abstract

The present invention relates to a load device for detecting the performance of a massage chair movement, comprising a movement hanger, a movement fixing module and a movement load applying module. The massage chair movement has the functions of walking, knocking and kneading. The movement fixing module is installed at the front end of the movement hanger, and is used to realize the placement and fixation of the movement and the addition of load to the movement when the movement performs the walking function. The movement load applying module is installed at the rear end of the movement hanger, and is used to realize the addition of load to the movement when the movement performs the knocking and kneading functions and to ensure the stability of the entire device. This device can provide a load when the movement performs a function, so that the movement can run under load. After the movement runs for a period of time under this condition, other devices are used to detect the movement to determine whether the quality of the movement is qualified. Multiple devices can be carried out simultaneously. As shown in the abstract figure, three devices can be carried out simultaneously. The figure shows one of the devices and a movement placed on the device. The device of the present invention is suitable for mass production of massage chair movements, which greatly improves the detection quality.

Description

Technical Field

[0001] The invention relates to a load device for detecting the performance of a massage chair movement, and is applied to the field of massage chair movement detection. Background Art

[0002] Currently, components must be screened for performance before leaving the factory to eliminate components that fail early. The massage chair movement test is to hang the massage chair movement on the massage chair frame under no-load conditions to perform a series of functions, and perform relevant tests during the execution process to determine whether the movement is qualified. This method of testing the massage chair movement under no-load conditions can cause incorrect judgments, because during normal use, when a person lies on a massage chair, the movement will be subject to load. A qualified movement tested in this case may not function for a short time during normal use. There is currently little research on this technology. Based on this situation, it is indeed necessary to develop a load device for testing the performance of massage chair movements. Summary of the invention

[0003] The present invention realizes applying a load to a massage chair movement, allowing the movement to perform walking, knocking and kneading functions under the load, thereby improving the accuracy of the performance detection of the massage chair movement.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: after the movement is placed in the device, the mechanical structure design is used to enable the movement to achieve the application of load when performing the walking, knocking and kneading functions. When the movement is placed and fixed, the modules for placing the movement on the device will be different due to different movement types and different moduli of the movement pinion. In order to achieve versatility, large gears with fixed moduli are installed on the upper and lower sides of the side of the movement gear placement block. Large gears with the same modulus are selected according to the modulus of the movement pinion gear to mesh, and then the movement is hung on the movement fixing module, thereby determining the position of the wheel used to perform the walking function in the movement, and also fixing the rotation of the wheel to prevent the movement from moving. The movement gear placement block can be loosened and tightened by the quick release screw to achieve the movement and fixation of the movement gear placement block to adapt to movements of different sizes. The connection between the movement optical axis side hook and the slider and the looseness of the clamp can achieve the movement and fixation of the movement optical axis side hook, thereby ensuring the other end of the fixed movement, and the massage template can be loosened and tightened by adjusting the pad. The device can realize the placement and fixation of movements of different models and sizes.

[0005] The massage chair movement has the functions of walking, pushing and kneading. When the movement performs the walking function, the gear shaft of the large gear is connected to the tension spring through the crank arm in the movement fixing module. As the movement performs the walking function, the small gear on the movement drives the large gear to rotate, and the crank arm pulls the tension spring to generate displacement and tension, thereby realizing the application of load to the tension spring when the movement performs the walking function; when the movement performs the knocking and kneading function, the movement hanger is connected to the movement load application module through the movement hanger guide shaft to determine the direction of its adjustment frame, and the adjustment frame and the kneading template are fixed by the kneading template guide shaft. The direction of the adjustment frame and the kneading module are aligned with the movement, and the massage template is adjusted and fixed with an adjustment pad to prevent the massage template from moving. The cylinder converts heat energy into mechanical energy through the air source provided by the compressed air equipment to ensure the stability of the device when the movement is operating. The movement performs the knocking and kneading function to cause the compression spring to displace, thereby realizing the application of the movement load, and a buffer is used to prevent the cylinder from exerting too much force on the adjustment frame, thereby impacting the kneading template, and the movement from exerting too much force on the kneading template when operating, thereby impacting the adjustment frame.

[0010] See the instruction manual Figure 1 As shown, the present invention is a load device for detecting the performance of a massage chair movement, which is applied to the field of massage chair movement detection and is characterized in that it is composed of a movement load application module (1), a movement hanger (2) and a movement fixing module (3). The movement load application module (1) is mainly used to ensure the stability of the device and to apply a load to the massage chair movement when performing the knocking and kneading functions, and the movement fixing module (3) is mainly used to place and fix the movement (4) and to apply a load to the massage chair movement when performing the walking function.

[0011] See the instruction manual Figure 2As shown, the movement load application module (1) is composed of a cylinder (1-1), two movement hanger guide shafts (1-2), an adjustment frame (1-3), two kneading template guide shafts (1-4), two buffers (1-5), two compression springs (1-6), and a kneading template (1-7). The movement load application module (1) is connected to the movement hanger (2) through the movement hanger guide shaft (1-2) to determine the direction of the adjustment frame (1-3). The adjustment frame (1-3) is connected to the kneading template (1-7) through the kneading template guide shaft (1-4) to determine the direction of the kneading template (1-7) so that the adjustment frame (1-3) and the kneading template (1-7) are aligned with the movement. When the compressed air device provides a constant air source, the cylinder (1-1) applies a constant force to the adjustment frame (1-3), and the bolts are tightened at the corresponding positions of the compression spring (1-6) on the adjustment frame (1-3), and the compression spring (1-6) is compressed to ensure the stability of the device when the movement is operating; when the movement performs the knocking and kneading functions, the compression spring (1-6) is displaced, thereby realizing the application of load when the movement is operating, and a buffer (1-5) is installed at the corresponding position on the adjustment frame to prevent the cylinder (1-1) from exerting too much force on the adjustment frame (1-3) and thus impacting the kneading template (1-7), and the movement from exerting too much force on the kneading template (1-7) and thus impacting the adjustment frame (1-3) when the movement is operating.
