Description

Technical Field

[0001] The utility model relates to the technical field of blowers, in particular to a vibration damping structure of a blower. Background Art

[0002] An automotive air conditioning assembly is used to realize functions such as refrigeration, heating, ventilation, and air purification of the air inside the vehicle compartment, so as to provide a comfortable riding environment for passengers. And the blower, as an important component in the automotive air conditioning assembly system, provides flowing wind power for the system. A utility model patent with the authorization announcement number CN220015542U discloses a blower, which includes a heat dissipation base. At least three fork-shaped parts are arranged on the heat dissipation base, and a U-shaped socket is arranged on the fork-shaped part. Its vibration damping structure includes a vibration damping seat, and an insertion ring groove is arranged on the vibration damping seat. The socket is clamped in the insertion ring groove to complete the fixation of the vibration damping seat. However, the above vibration damping structure has the following disadvantages:

[0003] 1. Since the vibration damping seat is a cylindrical structure as a whole, and the socket is also an open socket, after the socket is inserted into the insertion ring groove of the vibration damping seat, there is always a small section of the insertion ring groove without any support, resulting in some defects in radial support.

[0004] 2. When the vibration damping seat supports the front cover and the rear cover, it is the two end faces of the vibration damping seat for support, and the contact area is large, so the compression amount is relatively large, and the vibration filtering effect is not obvious.

[0005] 3. Since the shock-absorbing seat is cylindrical, in order to ensure that the socket of the fork-shaped part has enough parts to be inserted into the insertion ring groove, the length of the fork-shaped part needs to be set relatively long, resulting in a relatively large size of the entire heat dissipation base. Summary of the Utility Model

[0006] The technical problem to be solved by the utility model is to provide a vibration damping structure of a blower, which has a better vibration filtering effect and can effectively reduce the length of the fork-shaped part.

[0007] To solve the above technical problems, the technical solution of the present utility model is: a vibration damping structure of a blower, including a plurality of vibration damping seats, each of which is sleeved on a fork-shaped part on the heat dissipation base of the blower one by one. The heat dissipation base is installed between the front cover and the rear cover of the blower through the vibration damping seats and the fork-shaped parts. The vibration damping seat includes a seat body made of a flexible material. A sleeve cavity sleeved on the fork-shaped part is provided on the seat body. One side of the sleeve cavity is provided with a sleeve opening for convenient insertion. Front inner ribs and rear inner ribs are respectively provided on the front inner wall and the rear inner wall of the sleeve cavity. Outer ribs are provided on other outer walls of the vibration damping seat. A receiving cavity for conveniently receiving the vibration damping seat is provided on the front cover and / or the rear cover. Connecting columns for convenient screw installation are provided on the front cover or the rear cover. A receiving groove for receiving the connecting columns is provided on the seat body. The cavity wall of the receiving cavity is in extrusion fit with the outer ribs.

[0008] As a preferred solution, the outer ribs include a front outer rib provided on the front outer wall of the vibration damping seat, a rear outer rib provided on the rear outer wall, a left outer rib provided on the left outer wall, a right outer rib provided on the right outer wall, and a far-side outer rib provided on the far-side away from the center of the front cover. The front outer rib and the rear outer rib are respectively connected with the corresponding front inner rib and rear inner rib to form a front total rib and a rear total rib.

[0009] As a preferred solution, the near-end of the front total rib and the rear total rib close to the center of the front cover extends towards the center and exceeds the edge of the sleeve opening.

[0010] As a preferred solution, the number of the far-side outer ribs is two, and the two far-side outer ribs are respectively connected to the ends of the left outer rib and the right outer rib.

[0011] As a preferred solution, a guiding structure for conveniently sleeving the vibration damping seat is provided on the fork-shaped part.

[0012] As a preferred solution, the guiding structure includes reinforcing ribs provided on the front panel and the rear panel of the fork-shaped part. The reinforcing ribs enclose a guiding groove and / or a guiding notch for conveniently sleeving the front inner rib and the rear inner rib.

[0013] As a preferred solution, a clamping notch for conveniently clamping the seat body is further provided on the reinforcing rib of the fork-shaped part. Correspondingly, a clamping edge adapted to the clamping notch is provided on the inner wall of the sleeve cavity.

[0014] As a preferred solution, the front outer rib, the rear outer rib, the left outer rib, the right outer rib and the far-side outer rib are all conical ribs.

[0015] After adopting the above technical solution, the effects of the present utility model are as follows: Since the damping seat includes a seat body made of a flexible material, a sleeve cavity sleeved on the fork-shaped part is arranged on the seat body, one side of the sleeve cavity is provided with a sleeve opening for convenient insertion, front inner ribs and rear inner ribs are respectively arranged on the front inner wall and the rear inner wall of the sleeve cavity, outer ribs are arranged on other outer walls of the damping seat, an accommodation cavity for conveniently accommodating the damping seat is arranged on the front cover and / or the rear cover, connecting columns for convenient screw installation are arranged on the front cover or the rear cover, an accommodation groove for accommodating the connecting columns is arranged on the seat body, and the cavity wall of the accommodation cavity is in extrusion fit with the outer ribs. Therefore, firstly, the outer ribs on the seat body are in extrusion fit with the front cover and the rear cover, and the front inner ribs and the rear inner ribs are in extrusion fit with the fork-shaped part, so that the contact area is further reduced, thereby reducing the compression amount and improving the vibration filtering effect. Secondly, the seat body is directly sleeved on the fork-shaped part through the sleeve opening. In this way, the fork-shaped part does not need to be too long for good sleeving, so the size of the heat dissipation base can be reduced, and then the size of the whole blower can be optimized.

[0016] Also, since the outer ribs include a front outer rib arranged on the front outer wall of the damping seat, a rear outer rib arranged on the rear outer wall, a left outer rib arranged on the left outer wall, a right outer rib arranged on the right outer wall, and a far-side outer rib arranged on the far-side away from the center of the front cover, the front outer rib and the rear outer rib are respectively connected with the corresponding front inner rib and rear inner rib to form a front total rib and a rear total rib. Therefore, the front total rib and the rear total rib are simpler to form, and the overall force is more reasonable. The near-end of the front total rib and the rear total rib close to the center of the front cover extends towards the center and exceeds the edge of the sleeve opening, so that the part contacting the fork-shaped part can be closer to the center, thereby further improving the vibration filtering effect without increasing the contact area too much.

[0017] Also, since the number of the far-side outer ribs is two, and the two far-side outer ribs are respectively connected to the ends of the left outer rib and the right outer rib, the strength of the seat body can be further improved.

[0018] Also, since a guiding structure for conveniently sleeving the damping seat is arranged on the fork-shaped part. The guiding structure includes reinforcing ribs arranged on the front panel and the rear panel of the fork-shaped part, and the reinforcing ribs enclose a guiding groove and / or a guiding notch for conveniently sleeving the front inner rib and the rear inner rib, so that the seat body can be better and more accurately sleeved on the fork-shaped part.

[0019] Moreover, a clamping notch for facilitating the insertion of the seat body is provided on the reinforcing rib of the forked portion. Correspondingly, a clamping edge adapted to the clamping notch is provided on the inner wall of the sleeve cavity, so that the sleeve cavity can be better sleeved onto the forked portion. After the clamping edge and the clamping notch cooperate, the stability of the seat body can be ensured, which facilitates the assembly of each damping seat and the heat dissipation base between the front cover and the rear cover.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] The present invention will be further described in detail below through specific embodiments.

[0029] As Figures 1 to 6 shown, a damping structure of a blower, the plurality of damping seats 3, the damping seats 3 are sleeved one by one on the forked portions 11 on the heat dissipation base 1 of the blower, a U-shaped socket 12 is provided on the forked portion 11, and the heat dissipation base 1 is mounted between the front cover 2 and the rear cover of the blower through the damping seats 3 and the forked portions 11.

[0030] The damping seat 3 includes a seat body 31 made of a flexible material. The seat body 31 is selected as liquid silicone, and of course it can also be rubber, such as EPDM. A sleeve cavity 32 is provided on the seat body 31 and is sleeved on the fork-shaped portion 11. One side of the sleeve cavity 32 is provided with a sleeve opening for convenient insertion. On the front inner wall and the rear inner wall of the sleeve cavity 32, a front inner rib 34 and a rear inner rib 33 are respectively provided, as Figure 1 shown, Figure 1 which shows a schematic diagram with the rear side of the front cover 2 facing up; Outer ribs are provided on other outer walls of the damping seat 3. An accommodation cavity 22 for conveniently accommodating the damping seat 3 is provided on the front cover 2 and / or the rear cover. Connecting columns 21 for convenient screw installation are provided on the front cover 2 or the rear cover. An accommodation groove 39 for accommodating the connecting column 21 is provided on the seat body 31. The connecting column 21 is located in the accommodation groove 39, and the accommodation groove 39 matches the U-shaped socket 12. Finally, it is fixed with bolts. In this way, the damping seat 3 is squeezed between the front cover 2 and the rear cover, and the cavity wall of the accommodation cavity 22 is in extrusion fit with the outer ribs, thereby achieving the damping effect.

[0031] The outer ribs include a front outer rib 35 provided on the front outer wall of the damping seat 3, a rear outer rib 36 on the rear outer wall, a left outer rib 37 on the left outer wall, a right outer rib 311 on the right outer wall, and a far-side outer rib 38 provided on the far-side away from the center of the front cover 2. The front outer rib 35 and the rear outer rib 36 are respectively connected to the corresponding front inner rib 34 and rear inner rib 33 to form a front total rib and a rear total rib. The front outer rib 35, the rear outer rib 36, the left outer rib 37, the right outer rib 311, and the far-side outer rib 38 are all conical ribs. Of course, other shapes can also be adopted, such as arc-shaped ribs or circular ribs.

[0032] The proximal ends of the front total rib and the rear total rib close to the center of the front cover 2 extend towards the center and exceed the edge of the sleeve opening. In this way, the lengths of the front total rib and the rear total rib are longer than that of the seat body 31. Without increasing the length of the fork-shaped portion 11, the front total rib and the rear total rib can filter vibration better. At the same time, the size of the seat body 31 does not increase, and the size of the overall heat dissipation base 1 does not increase either, thereby optimizing the size of the blower.

[0033] As Figure 4 and Figure 5 shown, the number of the far-side outer ribs 38 is two, and the two far-side outer ribs 38 are respectively connected to the ends of the left outer rib 37 and the right outer rib 311.

[0034] As Figure 6As shown, a guiding structure for facilitating the insertion of the damping seat 3 is provided on the fork-shaped part 11. The guiding structure includes reinforcing ribs 111 provided on the front panel and the rear panel of the fork-shaped part 11. The reinforcing ribs 111 enclose a guiding groove 112 and / or a guiding notch 113 for facilitating the insertion of the front inner convex rib 34 and the rear inner convex rib 33. Among them, in this embodiment, the number of both the front total convex ribs and the rear total convex ribs is three. In the solution of this embodiment, both the guiding groove 112 and the guiding notch 113 are provided, so as to achieve better guiding and at the same time restrict the position of the seat body 31.

[0035] Among them, a clamping notch 114 for facilitating the clamping of the seat body 31 is further provided on the reinforcing rib 111 of the fork-shaped part 11. Correspondingly, a clamping edge 310 adapted to the clamping notch 114 is provided on the inner wall of the sleeving cavity 32. After the sleeving cavity 32 of the seat body 31 is sleeved on the fork-shaped part 11, the clamping edge 310 will be clamped into the clamping notch 114, thereby preventing the seat body 31 from sliding out.

[0036] Compared with the solution in the background technology, the solution in this embodiment first changes the shape of the seat body 31, adopts the way of directly wrapping the fork-shaped part 11 completely, and has good damping effects in both the axial direction and the radial direction. Secondly, the contact area between the seat body 31 and the front cover 2, the rear cover, and the heat dissipation base 1 is reduced, so as to reduce the compression amount. Finally, the sleeving mode of the seat body 31 further reduces the length of the fork-shaped part 11 compared with the length of the fork-shaped part 11 in the background technology, thereby optimizing the size of the heat dissipation base 1 and further optimizing the size of the blower.

[0037] The above embodiments are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and modifications made to the technical solution of the present invention shall fall within the protection scope determined by the claims of the present invention.
