A floating connection module and a smart bracelet acoustic performance test equipment

Abstract

The invention belongs to the technical field of acoustic performance testing equipment, and discloses a floating connection module and an acoustic performance testing equipment for a smart bracelet. The floating connection module includes a first base plate, a first floating structure and a second floating structure; the first floating structure includes a floating plate, two floating connection blocks and two L-shaped support blocks; the horizontal base plate of the L-shaped support block is fixedly connected to the On the first bottom plate, the vertical plate is floatingly connected to the front end of the floating connection block through equal height screws and the first compression spring; the rear bottom end of the floating connection block is fixedly connected with the front end of the floating plate; There are several universal positioning balls at the bottom of the plate. The universal positioning balls can roll in any direction and float in the Z direction, including a cylinder, a ball that is movably clamped at the bottom of the cylinder, and a pre-compressed second compression spring. The invention can solve the problem that the positioning accuracy is difficult to guarantee when the floating direction is perpendicular to the bearing gravity direction, and improve the positioning connection accuracy and testing efficiency.

Description

technical field [0001] The invention belongs to the technical field of acoustic performance testing equipment, and particularly relates to a floating connection module and an acoustic performance testing equipment for a smart bracelet. Background technique [0002] The floating connection structure of equal-height screws and springs is widely used in mechanical design. When the floating direction is parallel to the gravity direction of the floating mechanism, the force of the floating spring can be increased to offset the gravity or pressure to achieve the effect of floating positioning. [0003] For example, the patent document CN208207007U discloses an automatic plugging and unplugging device, which includes a connecting plate and a test connector arranged on the machine base; the test connector is connected with the connecting plate through a floating connection structure; At least two elastic limit components of the elastic limit, the floating block can move relative to ...

Problems solved by technology

[0005] However, during the process of implementing the technical solutions invented in the embodiments of the present application, the inventors of the present application found that the above technical solutions have at least the following technical problems: when the floating direction of the floating mechanism is not parallel to or even perpendicular to the bearing gravity, such as figure 1 As shown, the floating direction of the floating mechanism is the X-axis, and the gravity is along the Z-axis. In this case, but when the spring force is too large, it will also affect the floating accuracy of the floating mechanism along the X-axis direction
