Description

TECHNICAL FIELD

[0001] The utility model relates to a shock attenuation fan without screw locking. BACKGROUND

[0002] The shock attenuation fan without screw locking refers to that during the installation of the fan, no screw or other fixing device is needed to fix the fan parts, but other technologies or designs are adopted to realize the shock attenuation effect.

[0003] At present, most devices need to use the fan for heat dissipation, and the fan is usually installed by using the screw, which leads to the problem that the rigid contact exists between the fan shell and other parts. When the fan operates, due to the rigid contact, the vibration is transmitted to other parts through the fan shell, which increases the vibration and noise of the whole device. SUMMARY

[0004] The utility model discloses a shock attenuation fan without screw locking, which solves the problem that the existing heat dissipation device usually installs the fan by using the screw, which leads to the problem that the rigid contact exists between the fan shell and other parts. When the fan operates, due to the rigid contact, the vibration is transmitted to other parts through the fan shell, which increases the vibration and noise of the whole device.

[0005] To achieve the above-mentioned purpose, the utility model provides a shock attenuation fan without screw locking, which comprises: a shell, a fixed plate is fixedly connected inside the shell, a circular groove is formed between the fixed plate and the outer side wall of the shell, a protrusion is connected between the fixed plate and the shell, a blowing device is installed in the circular groove, the blowing device comprises a rectangular block, a fan is rotatably arranged inside the rectangular block, a sleeve ring is sleeved on the outer side of the rectangular block, and a plurality of rubber blocks are fixedly arranged on the outer side of the sleeve ring.

[0006] As a further scheme of the utility model: the circular groove is communicated with the outside.

[0007] As a further scheme of the utility model: the protrusion is fixedly connected between the fixed plate and the shell and is close to the positions of both ends.

[0008] As a further scheme of the utility model: a SOC board and an MCU board are fixedly installed inside the shell.

[0009] Compared with the prior art, the utility model has the beneficial effects that:

[0010] By setting the rubber blocks, the sleeve ring is aligned with the circular groove and embedded, the rubber blocks on the outer side of the sleeve ring contact the protrusion, the inner wall of the shell and the inner wall of the fixed plate, the rubber blocks are extruded and elastically contracted, and the rigid contact between the sleeve ring and other parts is avoided.

[0015] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0016] like Figs. 1-3 As shown, a vibration-damping fan that does not require screw fastening includes: a housing 1, a fixing plate 9 fixedly connected inside the housing 1, and a circular groove 2 formed between the fixing plate 9 and the outer side wall of the housing 1, the circular groove 2 communicating with the outside.

[0017] A protrusion 6 is fixedly connected between the fixing plate 9 and the outer shell 1, near both ends.

[0018] A blower is installed inside the circular groove 2. The blower includes a rectangular block 4. A fan 3 is rotatably installed inside the rectangular block 4. A collar 5 is sleeved on the outside of the rectangular block 4. Several rubber blocks 10 are fixedly installed on the outside of the collar 5.

[0019] The specific process of installing the blower into the circular groove 2 is as follows: Align the collar 5 with the circular groove 2 and insert it in. The rubber block 10 on the outside of the collar 5 contacts the protrusion 6, the inner wall of the outer shell 1, and the inner wall of the fixing plate 9. The rubber block 10 is squeezed and elastically contracts to avoid the collar 5 from rigidly contacting other parts.

[0020] The SOC board 7 and MCU board 8 are fixedly installed inside the outer casing 1.

[0021] Working principle:

[0022] The specific process of installing the blower into the circular groove 2 is as follows: Align the collar 5 with the circular groove 2 and insert it in. The rubber block 10 on the outside of the collar 5 contacts the protrusion 6, the inner wall of the outer shell 1, and the inner wall of the fixing plate 9. The rubber block 10 is squeezed and elastically contracts to avoid the collar 5 from rigidly contacting other parts.

[0023] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
