As shown in fig. 1 to 13, the present embodiment provides a water pump assembly including a water pump 1, the water pump 1 including a water pump body 11 and a limit projection 12 connected to the water pump body 11.

Further, the water pump assembly further comprises a mounting bracket 2, the mounting bracket 2 comprises a base 21 and a clamping frame 22, and the base 21 is connected with the clamping frame 22 and used for clamping the water pump 1.

The clamping frame 22 comprises a first arc-shaped section 221 and a second arc-shaped section 222, and a limiting space 205 for installing the water pump 1 is formed between the first arc-shaped section 221 and the second arc-shaped section 222. The first arc-shaped section 221 and the second arc-shaped section 222 are respectively provided with a limiting groove 205a, and the limiting grooves 205a are positioned in the limiting space 205 for installing the limiting protruding blocks 12.

In this embodiment, when the limit bump 12 of the water pump 1 is installed in the limit groove 205a of the first arc-shaped section 221 and the second arc-shaped section 222, the limit effect on the water pump 1 can be achieved, that is, the water pump 1 is prevented from rotating along the arc surfaces of the first arc-shaped section 221 and the second arc-shaped section 222. Meanwhile, the matching of the limiting lug 12 and the limiting groove 205a can facilitate the water pump 1 to be installed in an aligned mode, so that the normal function of the water pump 1 is guaranteed, namely the reciprocating circulation of cooling liquid is promoted, and the purpose of heat dissipation is achieved.

As shown in fig. 2 and 3, the first arc-shaped section 221 and the second arc-shaped section 222 each include a connection end and an adjustment end a, the connection ends of the first arc-shaped section 221 and the second arc-shaped section 222 are connected, and the adjustment ends a of the first arc-shaped section 221 and the second arc-shaped section 222 are both connected with the base 21 in an adjustable manner, so as to adjust the distance between the adjustment ends a and a of the first arc-shaped section 221 and the second arc-shaped section 222, and further change the size of the limiting space 205, and finally enable the water pumps 1 with different sizes to be installed in the limiting space 205, so as to improve the universality of the mounting bracket 2.

For example, the first arc-shaped section 221 and the second arc-shaped section 222 may be metal structures and are integrated, and the distance between the adjusting end a of the first arc-shaped section 221 and the adjusting end a of the second arc-shaped section 222 is adjusted by the elastic property of the metal structures; or the connection end of the first arc segment 221 and the connection end of the second arc segment 222 may be connected in an articulated manner.

In this embodiment, when the distance between the adjusting end a of the first arc segment 221 and the adjusting end a of the second arc segment 222 is gradually increased, the limiting space 205 is synchronously increased, and the water pump 1 with a larger size can be installed; when the distance between the adjusting end a of the first arc-shaped section 221 and the adjusting end a of the second arc-shaped section 222 is gradually reduced, the limiting space 205 is synchronously reduced, and the water pump 1 with smaller size can be installed.

In this embodiment, the center of the first arc segment 221 coincides with the center of the second arc segment 222, so that the first arc segment 221 and the second arc segment 222 together form a circular structure, so as to more conveniently adapt to the shape of the water pump 1, and further facilitate the close fitting of the first arc segment 221 and the second arc segment 222 with the outer surface of the water pump 1.

Further, the first arc-shaped section 221 and the second arc-shaped section 222 are respectively provided with a plurality of limiting grooves 205a, and the limiting grooves 205a are mutually arranged on the first arc-shaped section 221 and/or the second arc-shaped section 222 at intervals along the length direction of the first arc-shaped section 221 or the second arc-shaped section 222; the water pump 1 includes a plurality of limiting protruding blocks 12, and the plurality of limiting protruding blocks 12 are disposed in one-to-one correspondence with the plurality of limiting grooves 205 a.

It should be understood that, when the diameter of the water pump 1 is far smaller than that of the first arc-shaped section 221 or the second arc-shaped section 222, the limit bump 12 of the water pump 1 can also be installed in the corresponding limit groove 205a, so as to prevent the water pump 1 from rotating along the arc surfaces of the first arc-shaped section 221 and the second arc-shaped section 222.

As shown in fig. 2 and fig. 3, the first arc-shaped section 221 and the second arc-shaped section 222 respectively include a side surface b and a clamping surface c positioned in the limiting space 205, and the side surface b is vertically connected with the clamping surface c; side b is provided with a buffer hole 206, and the buffer hole 206 is recessed towards the axial direction of the first arc-shaped section 221 or the second arc-shaped section 222; the limiting groove 205a is disposed on the clamping surface c and is recessed along the radial direction of the first arc segment 221 or the second arc segment 222.

In this embodiment, the buffer holes 206 are disposed on the side b of the first arc segment 221 and the second arc segment 222, and the buffer holes 206 can play a role in buffering vibration in the radial direction when the severe working condition of the vehicle is greatly excited, so as to improve the NVH performance of the whole vehicle.

Further, after the water pump 1 is assembled between the first arc-shaped section 221 and the second arc-shaped section 222, the clamping surface c of the first arc-shaped section 221 and the second arc-shaped section 222 is tightly attached to the water pump 1 and radially pressed, and the limiting groove 205a provided on the clamping surface c is clamped with the limiting bump 12 of the water pump 1.

It should be appreciated that NVH is one of the metrics for measuring vehicle comfort and is composed of three parts, namely N-noise, V-vibration, H-harshness.

Further, the side b is provided with a plurality of buffer holes 206, and the plurality of buffer holes 206 are elongated holes, so as to better promote the buffer effect of the clamping frame 22.

In this embodiment, the buffer holes 206 are spaced apart from each other and are disposed around the center of the first arc segment 221 or the center of the second arc segment 222, so that when the severe working condition of the vehicle is greatly excited, the water pump 1 is vibrated under the influence of external factors, and the clamping frame 22 can uniformly absorb the vibration source.

In the present embodiment, as shown in fig. 8 and 9, a reinforcing rib 223 is provided in the buffer hole 206, and the reinforcing rib 223 is located at the middle section of the buffer hole 206 to partition the buffer hole 206 into the first buffer groove 206a and the second buffer groove 206b. The reinforcing ribs 223 support the buffer holes 206 in the buffer holes 206, preventing deformation of the holder 22, and thus making the installation of the water pump 1 unstable.

As shown in fig. 3 and 10, the base 21 is provided with a plurality of first positioning holes 201 spaced apart from each other and a plurality of second positioning holes 202 spaced apart from each other, the plurality of first positioning holes 201 and the plurality of second positioning holes 202 being spaced apart from each other; the circle centers of the first positioning holes 201 and the second positioning holes 202 are all positioned on the same straight line; the adjusting end a of the first arc-shaped section 221 can be matched with any one first positioning hole 201 in the plurality of first positioning holes 201 through the positioning piece 3 to realize the connection with the base 21; the adjusting end a of the second arc-shaped section 222 can be connected with the base 21 by matching the positioning piece 3 with any one of the second positioning holes 202 in the plurality of second positioning holes 202.

In the present embodiment, the positioning member 3 is a bolt. Of course, in other embodiments, the positioning member 3 may be a screw or the like.

In this embodiment, three first positioning holes 201 and three second positioning holes 202 are provided on the base 21, and the first positioning holes 201 and the second positioning holes 202 are all the same circular holes. The first positioning holes 201 and the second positioning holes 202 at different positions are matched and combined, so that the clamping frame 22 can be fixed at different positions, the assembly of water pumps 1 with different sizes can be indirectly met, the universalization level of parts is improved, and the cost input of newly opened parts is reduced.

Further, six identical nuts matched with bolts are provided on the other side connected with the holder 22, and the nut and bolt matching connects the holder 22 with the base 21 so that the holder 22 is closely attached to the base 21.
