Description

Fan mounting assembly, lighting device and vehicle

Technical Field

The utility model relates to the technical field of heat dissipation devices, in particular to a fan mounting assembly, and a lighting device and a vehicle adopting the fan mounting assembly.

Background

In the prior art, when it is required to mount and fix a fan to a mount, the following schemes are generally adopted:

scheme 1: an additional pressing plate is used. The pressing plate presses the fan on the mounting seat and both ends of the pressing plate are provided with fastening structures, and then the purpose of mounting the fan on the mounting seat is achieved by fastening the pressing plate on the mounting seat. The purpose of this solution is to require additional components and to be inconvenient to disassemble.

Scheme 2: screw holes are formed in the housing of the fan, and then the fan is fixed to the mounting seat by using screws. This solution has the disadvantage of requiring additional components and increasing the complexity of the fan housing itself and of being inconvenient to disassemble.

Scheme 3: a plurality of clamping structures are arranged on the mounting seat. The fan is clamped by the clamping structure, so that the purpose of installing the fan on the installation seat is achieved. However, the type and size of the clamping structure need to be selected according to the installation environment, which is not beneficial to standardization, and the production process of some clamping structures is complex and the cost is high.

The present utility model has been made to solve at least some of the above-mentioned problems, and other technical problems that are potential.

According to an aspect of the present utility model, there is provided a mounting assembly for a fan, the mounting assembly for a fan comprising a fan and a fan mount. The fan has a plurality of claws distributed along a circumferential direction of the fan. The fan mounting seat is provided with a plurality of clamping tongues distributed along the circumferential direction of the fan mounting seat, and concave parts are formed between every two adjacent clamping tongues. Each jaw of the fan can be inserted into and pass through a corresponding recess of the fan mount in an axial direction of the fan and then rotated by an angle in a circumferential direction of the fan such that each jaw of the fan is caught by a corresponding catch of the fan mount to mount the fan to the fan mount. The mounting assembly is suitable for being conveniently and quickly dismounted, so that the dismounting efficiency is improved; the method is suitable for standardization and can be applied to different installation environments; the production process is simple and the cost is low.

Fig. 8 is a partially cut-away perspective view of a portion of a mounting assembly of a fan according to an exemplary embodiment of the present utility model.

As shown in fig. 1 to 8, a mounting assembly 1 of a fan according to an exemplary embodiment of the present utility model mainly includes a fan 11 and a fan mount 21.

The fan 11 has a circular peripheral wall 111, an impeller 112 surrounded by the peripheral wall 111, and a center support 113 fixedly connected to the peripheral wall 111. On the outer peripheral surface of the center pillar 113, a plurality of (three in the present exemplary embodiment) claws 1a, 1 b, 114c are distributed in the circumferential direction.

The fan mount 21 has a base plate 211. Around the center hole 212, a plurality of (three in the present exemplary embodiment)

tabs

213a, 213b, 213c are distributed along the circumferential direction of the fan mount 21, and

recesses

214a, 214b, 214c are formed between each two adjacent tabs.

Each of the claws 1a, 1 b, 114c is capable of being inserted into and passed through the

corresponding recess

214a, 214b, 214c of the fan mount 21 in the axial direction of the fan 11 (the direction shown by an arrow R1 in fig. 9 and 11, described later), and then rotated by an angle in the circumferential direction of the fan 11 (the direction shown by an arrow R2 in fig. 7 and 10, described later), so that each of the

claws

114a, 114b, 114c is caught by the

corresponding catch

213a, 213b, 213c of the fan mount 21 to mount the fan 11 to the fan mount 21.

As shown in fig. 4, 6 and 7, the mounting assembly 1 of the fan further comprises an elastomer 115. The elastic body 115 is installed between the fan 11 and the fan mount 21. When the fan 11 is mounted on the fan mount 21, the elastic body 115 is compressed, and the resultant resilient force causes the fan 11 to be firmly mounted on the fan mount 21. In particular, the elastic body 115 may be an elastic pad that may be provided on the fan 11 and/or the fan mount 21, for example, on a surface 211a of the substrate 211 facing the fan 11. The elastic body 115 may be configured as a gasket, and may be configured as a gasket to seal a gap between the fan 11 and the fan mount 21. In this way, the sealing of the gap between the fan 11 and the fan mount 21 can be achieved without increasing the number of parts.

As shown in fig. 4, each of the

tabs

213a, 213b, 213c has a corresponding

inclined surface

216a, 216b, 216c. As each

jaw

114a, 1 b, 114c rotates in the circumferential direction of the fan 11 after being inserted into and passed through the

corresponding recess

214a, 214b, 214c, each

jaw

114a, 114b, 114c slides along the corresponding

inclined surface

216a, 216b, 216c. In this way, due to the

inclined surfaces

216a, 216b, 216c, the

respective claws

114a, 114b, 114c are advanced in the axial direction of the fan 11 while rotating in the circumferential direction of the fan 11.

Preferably, the

tabs

213a, 213b, 213c may also have

corresponding slots

217a, 217b, 217c. The shape of the clamping

grooves

217a, 217b, 217c is configured to accommodate the

respective jaws

213a, 213b, 213c. In the rotational direction of each

jaw

213a, 213b, 213c, each

catch

217a, 217b, 217c is located downstream of the corresponding

inclined face

216a, 216b, 216c. After each

jaw

213a, 213b, 213c slides along the respective

inclined surface

216a, 216b, 216c until rotated into place, each

jaw

213a, 213b, 213c is able to snap into the

respective catch slot

217a, 217b, 217c. In this way, the pawls 213a, 213b, 213c can be prevented from loosening due to unintentional reverse rotation.

Preferably, the mounting assembly 1 of the fan may also comprise a fool-proof structure. Specifically, the fool-proof structure may be configured to: the shape of at least one of the plurality of

claws

114a, 114b, 114c (the claw 1a in the present exemplary embodiment) is different from the shape of the other claws (114 b, 114 c); and the shape of the corresponding recess (recess 214a in the present exemplary embodiment) into which at least one jaw (114 a) is inserted and through is different from the shape of the other recesses (214 b, 214 c) such that the at least one jaw (114 a) cannot be inserted and through the other recesses (214 b, 214 c). For example, as shown in fig. 4 and 5, the dimensions of the jaws 114a and corresponding recesses 214a are significantly larger than the dimensions of the

other jaws

114b, 114c and

recesses

214b, 214c. Thus, each

jaw

1, 1 b, 114c can be properly inserted into and through a

respective recess

214a, 214b, 214c if and only if jaw 114a is aligned with a respective recess 214 a. In this way, the fan 11 can be prevented from being erroneously mounted.

Optionally, the fool-proof structure may be further configured to: in the circumferential direction of the fan 11, the spacing between at least two of the plurality of

claws

114a, 114b, 114c is different from the spacing between the other claws. In this way, each

jaw

114a, 114b, 114c is able to be inserted into and through the

corresponding recess

214a, 214b, 214c if and only if the fan 11 is in the only correct relative angle/position with respect to the fan mount 21, thereby achieving the objective of avoiding incorrect mounting of the fan 11.

It will be appreciated that the fool-proof structure described above is merely exemplary. Where applicable and compatible, various types of fool-proof structures may be employed in combination.

Next, an installation process of the installation assembly of the fan according to an exemplary embodiment of the present utility model will be described mainly with reference to fig. 9 to 11. It should be appreciated that prior to mounting the fan 11 to the fan mount 21, the fan mount 21 is typically already secured to the aforementioned heat sink by means such as welding, riveting, integral molding, or the like.

As shown in fig. 9, the center support 113 of the fan 11 is first aligned with the center hole 212 of the fan mount 21, more precisely, the

claws

114a, 114b, 114c are aligned with the

recesses

214a, 214b, 214c, respectively, and then inserted into the corresponding

recesses

214a, 214b, 214c in the axial direction of the fan 11 (i.e., the direction indicated by the arrow R1).

Then, as shown in fig. 11, the

claws

114a, 1 b, 114c are further moved in the axial direction of the fan 11 (i.e., the direction shown by the arrow R1) at the respective

concave portions

214a, 214b, 214c until the

claws

114a, 114b, 114c pass through the respective

concave portions

214a, 214b, 214c, for example, by applying an external force to the fan 11. Reference herein to "the

claws

114a, 114b, 114c passing through the

respective recesses

214a, 214b, 214c" means that the

respective claws

114a, 114b, 114c are moved in the axial direction of the fan 11 to such an extent that they can rotate in the circumferential direction of the fan 11, specifically, means such an extent that the claws 1 b as shown in fig. 11 have completely passed over the circumferential side surfaces 215b of the catch tongues 213 b. Although not shown in the figures, it is conceivable that the

claws

114a and 114c have passed over the circumferential sides of the

tongues

213a and 213c, respectively. It should be noted that at this point the elastomer 115 begins or is already in a compressed state.

Then, as shown in fig. 10, by applying an external force to the fan 11, the fan 11 (each of the

claws

1a, 114b, 114c, respectively) is rotated by an angle (for example, 60 ° in the present exemplary embodiment) in the circumferential direction (i.e., the direction shown by the arrow R2 in fig. 7 and 1 0). As the fan 11 rotates in the circumferential direction, each

jaw

114a, 114b, 114c slides along the corresponding

inclined surface

216a, 216b, 216c. Due to the inclination of the

inclined surfaces

216a, 216b, 216c, the

respective claws

114a, 114b, 114c advance in the axial direction of the fan 11 while rotating in the circumferential direction of the fan 11. It is conceivable that the degree to which the elastic body 115 is compressed gradually increases in this process.

Then, by applying an external force to the fan 11, each of the

claws

1a, 114b, 114c is further rotated in the circumferential direction of the fan 11 until each of the

claws

213a, 213b, 213c is rotated to the position of the

corresponding card slot

217a, 217b, 217c, respectively. At this time, the application of external force to the fan 11 is stopped. Then, the fan 11 is moved in the direction opposite to the direction indicated by the arrow R1 by the resilience of the elastic body 115 until the

respective claws

213a, 213b, 213c are respectively fitted into the corresponding catching

grooves

217a, 217b, 217c. The presence of the

grooves

217a, 217b, 217c prevents the pawls 213a, 213b, 213c from coming loose due to unintentional reverse rotation. In this way, each

claw

114a, 114b, 114c is caught by the

corresponding catch

213a, 213b, 213c, thereby completing the work of mounting the fan 11 to the fan mount 21.

It should be noted that at this time, the elastic body 115 is in a compressed state as a whole although it has slightly sprung back, the resulting sprung back force makes the fan 11 firmly mounted on the fan mount 21, and the elastic body 115 can also function as a sealing gasket to seal the gap between the fan 11 and the fan mount 21.

The process of removing the fan 11 is also relatively simple. First, by applying an external force to the fan 11, the fan 11 is slightly moved in the direction indicated by the arrow R1 until each of the

claws

213a, 213b, 213c is removed from the corresponding

card slot

217a, 217b, 217c. Then, the fan 11 is rotated in the direction opposite to the direction indicated by the arrow R2 while gradually reducing the external force applied to the fan 11 until each of the

claws

213a, 213b, 213c is aligned with the

corresponding recess

214a, 214b, 214c. Then, the application of external force to the fan 11 is stopped to allow the

respective claws

213a, 213b, 213c to be removed from the

respective recesses

214a, 214b, 214c in the direction opposite to the direction indicated by the arrow R1. In this way, the work of detaching the fan 11 from the fan mount 21 is completed.

The fan mounting assembly according to the present utility model has a simple structure, is convenient to standardize, can be quickly assembled and disassembled, and is advantageous for large-scale application to lighting devices such as vehicles.

Although the technical objects, technical solutions and technical effects of the present utility model have been described in detail hereinabove with reference to specific embodiments, it should be understood that the above-described embodiments are merely exemplary and not limiting. Any modifications, equivalent substitutions, and improvements made by those skilled in the art are intended to be included within the spirit and principles of the present utility model.
