The utility model provides a prevent pressing sealing connection structure and have this prevent pressing sealing connection structure's wearable equipment, will use the wearable equipment that has this prevent pressing sealing connection structure as the example below, the structural component and the technological effect that this prevent pressing sealing connection structure and wearable equipment of detailed description.

Example one

The present embodiment proposes a wearable device, as shown in fig. 1, including a housing 11 and a speaker 12, wherein the speaker 12 is connected to the housing 11 through a pressure-proof seal connection structure.

As a preferred embodiment, as shown in fig. 1 to 3, an O-ring 13 is provided on the outer side wall of the speaker 12 in the circumferential direction.

The housing 11 has a fitting cavity 110 for fitting the speaker 12, an inner surface of the fitting cavity 110 is formed with a closed fitting groove 111, the O-ring 13 is fitted into the fitting groove 111 when the speaker 12 is fitted into the fitting cavity 110, and a stopper structure 112 is formed on a side wall of the fitting groove 111. The stopper 112 serves to block the speaker 12 from axially escaping from the fitting chamber 110 after the O-ring 13 is fitted in the fitting groove 111.

The housing 11 in this embodiment corresponds to a first connection body of the pressure-proof seal connection structure, and the housing 11 corresponds to a second connection body of the pressure-proof seal connection structure.

When assembling, under the action of the pressure device, the loudspeaker 12 is axially assembled into the assembly cavity 110 from the mouth of the assembly cavity 110, when the O-ring 13 moves to the assembly groove 111 in the process that the loudspeaker 12 moves axially, the extrusion force of the assembly cavity 110 to the O-ring 13 is suddenly reduced, the O-ring 13 with elasticity is deformed under the action of the restoring force of the O-ring 13, at least part of the O-ring 13 is embedded into the assembly groove 111, and in order to realize the sealing function of the loudspeaker 12 and the assembly cavity 110, the O-ring 13 and the assembly groove 111 are in an interference fit mode.

When the speaker 12 is subjected to pressure of liquid or gas in the axial direction at the time of use or test, the resistance to the relative movement of the speaker 12 and the fitting chamber 110 in the axial direction can be increased by fitting the O-ring 13 into the fitting groove 111.

By forming the stopping structure on the side wall of the assembling groove 110 for stopping the loudspeaker 12 from axially separating from the assembling cavity 110, the O-ring 13 can be limited in the assembling groove 110, the O-ring 13 is prevented from separating from the assembling groove 110, and the stability and reliability of the sealed connection between the loudspeaker 12 and the assembling cavity 110 are further improved.

A front cavity space 113 is formed between the loudspeaker 12 and the bottom of the assembly cavity 110, a sound hole 114 penetrating through the front cavity space 113 is formed in the shell 110, and sound emitted by the loudspeaker 12 can enter the front cavity space 113 and then can penetrate out of the wearable device through the sound hole 114.

The height of the front space 113 is set in advance so that the optimum sound emission state can be achieved. When the speaker 12 is moved by the axial pressure, the size of the front space 113 is changed regardless of whether it is moved toward the mouth or the bottom of the front space 113, and the high frequency uniformity is deteriorated, which affects the sound quality.

When a user wears the wearable device for swimming or the wearable device is subjected to a waterproof test, external liquid or high-pressure gas enters the front cavity space 113 through the sound hole 114, water pressure or air pressure acts on the surface of the speaker 12 facing the front cavity space 113 to generate pressure for moving the speaker 12 axially towards the mouth of the assembly cavity 110, and in the embodiment, the stop structure 112 is formed on one side wall of the assembly groove 111 close to the mouth of the assembly cavity 110, that is, the stop structure 112 can provide a reaction force opposite to the pressure to the O-ring, so that the speaker 12 can be effectively prevented from being displaced.

The speaker 12 is firmly assembled in the assembly cavity 110 without displacement, which is beneficial to ensuring the stability of the audio effect and maintaining strong waterproof performance.

As shown in fig. 3, the stopping structure 112 extends obliquely away from the mouth of the assembling cavity 110 and forms a barb-like structure with the inner wall of the assembling cavity 110, so as to tightly clamp the O-ring 13 in the assembling groove 111.

In order to prevent the barbed end of the stopper 112 from piercing the O-ring 13 and losing the sealing effect, it is preferable that the free end of the stopper 112 is formed with a curved edge to increase the contact area with the O-ring 13 and reduce damage to the O-ring 13.

A side wall of the fitting groove 111 away from the mouth of the fitting cavity 110 extends obliquely towards the bottom of the fitting groove 111, the extending direction of the side wall is along the direction of the external pressure applied to the speaker 12, and the side wall forms an obtuse angle with the bottom of the fitting groove 111, so that the side wall can play a role in guiding the O-ring 13 when the speaker 12 is applied with the external pressure, and the O-ring can be clamped by the stopping structure 112.

In order to prevent the O-ring 13 from being separated from the assembling groove 111, the width of the notch of the assembling groove 111 is 1/3-1/2 of the diameter of the O-ring, and the O-ring 13 is limited in the radial direction.

As shown in fig. 1, the baffle plate 14 is fixed to the mouth of the fitting chamber 110, and can contact with a surface of the speaker 12 facing the mouth of the fitting chamber 110, thereby functioning to stop the operation of the speaker 12.

The blocking sheet 14 can be made of metal material, so that the strength of the stopping and limiting of the blocking sheet is improved. The flap 14 may be fixed to the housing 11 by, but not limited to, screw fixation.

Since the space of the wearable device is limited and the strength of the corresponding barrier 14 is limited, in order to prevent the loudspeaker 12 from generating a large impact force on the barrier 14, which may cause the barrier 14 to be damaged, it is preferable to provide a buffering foam 15 between the barrier 14 and the loudspeaker 12. The cushion foam 15 can serve to cushion the impact force on the baffle 14.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
