Anti-vibration damping type fan assembly

Abstract

A shock-absorbing fan assembly includes a fan body, at least one cover plate, at least one fastener, and at least one shock-absorbing sleeve. The fan body has at least one body fixing channel. The cover plate has at least one cover plate fixing hole corresponding to the body fixing channel. The fastener passes through the body fixing channel and the cover plate fixing hole, thereby fixing the cover plate and the fan body relative to each other. The shock-absorbing sleeve passes through at least one of the body fixing channel and the cover plate fixing hole, or is sleeved on the fastener, thereby ensuring tight contact with the fastener when the fastener passes through the body fixing channel and the cover plate fixing hole, and correspondingly ensuring tight contact with at least one of the fan body and the cover plate at at least one of the body fixing channel and the cover plate fixing hole.

Claims

1. A shock-absorbing and buffering fan assembly, comprising: a fan body having at least one body fixing channel; at least one cover plate having at least one cover plate fixing hole corresponding to the body fixing channel, and including a front cover and a rear cover, the front cover and the rear cover being respectively fixed to opposite sides of the fan body, wherein, The aforementioned cover plate fixing hole on the front cover is a lock hole, and the aforementioned cover plate fixing hole on the rear cover is a through hole; at least one fastener is provided through the aforementioned body fixing channel and the aforementioned cover plate fixing hole, so as to fix the aforementioned cover plate and the fan body relative to each other, wherein the aforementioned fastener is a locking fastener and includes: a through section for sequentially passing through the through hole and the aforementioned body fixing channel; A locking section extends from the through section and is used to lock into the lock hole after the through section passes through the through hole and the aforementioned body fixing channel; and an operating section extends from the through section away from the locking section and is used to rotate the locking section and lock it into the lock hole after being operated; and at least one shock-absorbing sleeve is inserted into at least one of the aforementioned body fixing channel and the aforementioned cover plate fixing hole, or sleeved on the aforementioned fixing member, so as to closely contact the aforementioned fixing member when the aforementioned fixing member passes through the aforementioned body fixing channel and the aforementioned cover plate fixing hole, and correspondingly closely contact the fan body and the aforementioned cover plate at at least one of the aforementioned body fixing channel and the aforementioned cover plate fixing hole.

2. The shock-absorbing fan assembly as described in claim 1, wherein, The aforementioned shock-absorbing sleeve is made of rubber.

3. The shock-absorbing fan assembly as described in claim 1, wherein, The through section has at least one fitting space, so that the shock-absorbing sleeve can be fitted onto the fastener in the fitting space using an in-mold integral forming technology.

4. The shock-absorbing fan assembly as described in claim 1, wherein, The aforementioned body fixing channel is formed by two body fixing holes aligned with each other. The aforementioned body fixing holes are respectively adjacent to the front cover and the rear cover. The aforementioned shock-absorbing and buffer sleeve is inserted through the aforementioned body fixing holes and includes: a body portion for inserting through the aforementioned body fixing holes; and two limiting portions extending from both sides of the body portion to jointly limit the body portion after it is inserted through the aforementioned body fixing holes, so that the aforementioned shock-absorbing and buffer sleeve remains inserted through the aforementioned body fixing holes.

5. The shock-absorbing fan assembly as described in claim 4, wherein, The aforementioned limiting part has a guide slope to guide the main body part through the aforementioned main body fixing hole.
