Detailed Description
The embodiment of the invention provides a massage chair weight detection module 9, which comprises an upper cover 1 for supporting a massage chair. Referring to fig. 1, the upper cover 1 is fixed to the bottom of the massage chair. Further comprising: a lower cover 2, the lower cover 2 is placed on the ground, the lower cover 2 is connected with the upper cover 1 to support the upper cover 1 and the massage chair. And the force measuring assembly is arranged between the upper cover 1 and the lower cover 2, so that the upper cover 1 and the lower cover 2 are arranged at intervals. The pin shaft 3, the pin shaft 3 is fixedly arranged on the upper cover 1. The limiting groove 4 is arranged in the lower cover 2, the limiting groove 4 is arranged corresponding to the pin shaft 3, so that the pin shaft 3 can rotate and reciprocate in the limiting groove 4, and the pin shaft 3 can be clamped by two opposite side walls of the limiting groove 4 in the reciprocating process in the limiting groove 4.
When a user sits on the massage chair, the upper cover 1 presses the force measuring component and forces the force measuring component to deform to a certain degree, and meanwhile, the pin shaft 3 moves downwards in the limiting groove 4. The mass detection module 9 of the massage chair can drive the upper cover 1 to rotate around the pin shaft 3 with the pin shaft 3 as a rotation center relative to the lower cover 2 by a certain angle because the pin shaft 3 can rotate and reciprocate in the limit groove 4. Therefore, the lower cover 2 can actively adapt to uneven ground, so that the lower surface of the lower cover 2 is kept close to the ground, and the measurement precision of the massage chair weight detection module 9 is kept accurate. In the process that the pin shaft 3 rotates in the limiting groove 4, as the side wall can clamp the pin shaft and allow the pin shaft to move up and down, the weight of the massage chair and a user thereon is borne by the force measuring component, and the measurement precision of the massage chair weight detection module can be kept accurate.
In the embodiment of the present invention, referring to fig. 4, the depth of the limit groove 4 is greater than the deformation degree of the force measuring assembly, so that the upper cover 1 and the lower cover 2 can freely rotate around the pin 3 with respect to each other before and after a user sits on the seat, and the upper cover 1 and the lower cover 2 are always spaced from each other. The depth of the limiting groove 4 is the distance between the bottom of the pin shaft 3 and the bottom of the limiting groove 4 in the vertical direction. Because the upper cover 1 extrudes the force measuring assembly and forces the force measuring assembly to deform downwards to a certain degree, and the pin shaft 3 is fixedly arranged on the upper cover 1, the pin shaft 3 can move downwards in the limit groove 4. When the depth of the limit groove 4 is greater than the deformation degree of the force measuring component, the pin shaft 3 cannot be pressed in the limit groove 4 and cannot rotate freely, so that the upper cover 1 can still rotate around the pin shaft 3 and the lower cover 2 when bearing the maximum load. In the process of weighing, the upper cover 1 and the lower cover 2 are always spaced from each other, and the load borne by the upper cover 1 is borne by the force measuring component; when the upper cover 1 and the lower cover 2 are in contact, the lower cover 2 will share a part of the load borne by the upper cover 1, resulting in a large error in the measurement result.

When the upper cover 1 is fastened to the lower cover 2, a certain distance is formed between the inner wall of the upper cover 1 and the outer wall of the lower cover 2 in the horizontal direction, so that the upper cover 1 can rotate relative to the lower cover 2 around the pin 3. When the upper cover 1 stops rotating when the upper cover 1 and the lower cover 2 are in contact with each other, the slope 5 can help increase the angle of rotation of the upper cover 1 relative to the lower cover 2 around the pin 3 when the inner wall edge of the lower cover 2 is higher than the outer wall edge of the lower cover 2 to form a slope 5 and the upper cover 1 first contacts the slope 5, so that the massage chair body weight detection module 9 can adapt to uneven ground with a larger inclination degree. In another embodiment, the side wall of the upper cover 1 only remains a portion for mounting the pin 3, and the upper cover 1 and the lower cover 2 are freely rotatable therebetween, and the rotational movement of the pin 3 in the stopper groove 4 is stopped only by the surface contact of the upper cover 1 with the slope 5.
