Abstract

The present disclosure discloses an electronic device. The electronic device comprises a first part, a second part and a connecting structure, the connecting structure comprises a first connector arranged on the first part and a second connector arranged on the second part, the electronic device further comprises at least one vibration absorbing structure, the vibration absorbing structure comprises elastic material arranged on the first part or the second part, wherein when the first part and the second part are connected by the connecting structure, the elastic material is compressed in a direction which is parallel to the direction in which the first connector and the second connector are connected with each other, such that a damping connection is established between the first part and the second part. The electronic device can achieve good vibration absorbing performance, low cost and high durability.

Claims (36)

1 . An electronic device comprising:

a first part;

a second part; and

a connecting structure comprising a first connector arranged on the first part and a second connector arranged on the second part;

wherein the electronic device further comprises at least one vibration absorbing structure, the vibration absorbing structure comprising elastic material arranged on the first part or the second part; and

wherein when the first part and the second part are connected by the connecting structure, the elastic material is compressed in a direction which is parallel to the direction in which the first connector and the second connector are connected with each other, such that a damping connection is established between the first part and the second part,

wherein the vibration absorbing structure comprises a first component arranged on one of the first part and the second part and a second component arranged on the other one of the first part and the second part, the first component comprises the elastic material, and the second component is configured to compress the elastic material when the first part and the second part are connected by the connecting structure, and

wherein:

the first component is a retaining sleeve with the elastic material arranged inside and at the bottom of the retaining sleeve; and

the second component is a guide pin, and wherein the tip of the guide pin compresses the elastic material when the first part and the second part are connected by the connecting structure.

2 . The electronic device according to claim 1 , wherein when the first part and the second part are connected by the connecting structure, the elastic material does not generate a force that deviates the first connector and the second connector from a mating position in a direction other than the direction in which the first connector and the second connector are connected with each other.

3 . The electronic device according to claim 1 , wherein before the elastic material is compressed, the surface of the elastic material is flat, concave or convex.

4 . The electronic device according to claim 1 , wherein the elastic material is rubber, silica gel, latex, plastic, sponge, or a spring.

5 . The electronic device according to claim 1 , wherein: the elastic material is pressed to the bottom of the retaining sleeve and self-sustain; or the elastic material is stuck to the bottom of the retaining sleeve by glue.

6 . An electronic device comprising:

a first part;

a second part; and

a connecting structure comprising a first connector arranged on the first part and a second connector arranged on the second part;

wherein the electronic device further comprises at least one vibration absorbing structure, the vibration absorbing structure comprising elastic material arranged on the first part or the second part,

wherein when the first part and the second part are connected by the connecting structure, the elastic material is compressed in a direction which is parallel to the direction in which the first connector and the second connector are connected with each other, such that a damping connection is established between the first part and the second part,

wherein the vibration absorbing structure comprises a first component arranged on one of the first part and the second part and a second component arranged on the other one of the first part and the second part, the first component comprises the elastic material, and the second component is configured to compress the elastic material when the first part and the second part are connected by the connecting structure, and

wherein:

the first component is an anti-vibration block made of the elastic material; and

the second component is one of a guide pin and a retaining sleeve, the tip of the guide pin or the retaining sleeve compresses the anti-vibration block when the first part and the second part are connected by the connecting structure.

7 . An electronic device comprising:

a first part;

a second part; and

a connecting structure comprising a first connector arranged on the first part and a second connector arranged on the second part;

wherein the electronic device further comprises at least one vibration absorbing structure, the vibration absorbing structure comprising elastic material arranged on the first part or the second part,

wherein when the first part and the second part are connected by the connecting structure, the elastic material is compressed in a direction which is parallel to the direction in which the first connector and the second connector are connected with each other, such that a damping connection is established between the first part and the second part,

wherein the vibration absorbing structure comprises a first component arranged on one of the first part and the second part and a second component arranged on the other one of the first part and the second part, the first component comprises the elastic material, and the second component is configured to compress the elastic material when the first part and the second part are connected by the connecting structure, and

wherein:

the first component comprises a protrusion with a contacting plane and an anti-vibration block made of the elastic material, the anti-vibration block is attached on the contacting plane of the protrusion; and

the second component is a contacting surface of the first part or the second part, the contacting surface compresses the anti-vibration block when the first part and the second part are connected by the connecting structure.

8 . The electronic device according to claim 7 , wherein: when the first component is arranged on the first part, the first component and the first connector are arranged on a same side of the first part; and when the first component is arranged on the second part, the first component and the second connector are arranged on a same side of the second part.

9 . The electronic device according to claim 7 , wherein one of the first part and the second part is a backplane of a chassis and the other one of the first part and the second part is a fan tray, wherein the first component is arranged on a first one of the backplane and the fan tray, and the second component is a contacting surface of the other one of backplane and the fan tray facing the first one.
