Description

TECHNICAL FIELD

[0001] The present application relates to a kind of automobile parts, specifically a kind of vibration isolation type electronic water pump. BACKGROUND

[0002] With the increasing popularity and application of new energy vehicles, the use of electronic water pumps is also increasing. In order to protect the comfort needs of people when traveling, it is necessary to reduce the noise generated during vehicle driving. Among the noises generated during vehicle driving, the noise generated during the operation of the electronic water pump is particularly prominent and needs to be reduced.

[0003] Current research has found that there are three main factors affecting the noise level of the electronic water pump during operation. One is the vibration caused by the motor slot torque inside the water pump, the second is the liquid pressure pulsation caused by the water pump impeller, and the third is the vibration isolation performance of the rubber vibration isolation pad. Compared with the first two factors, it is undoubtedly relatively low in cost to reduce the noise of the electronic water pump by starting from the rubber vibration isolation pad.

[0004] Generally, the rubber vibration isolation pad is usually placed and installed on the engine support, acting as a medium for connecting the electronic water pump and the engine support. However, the thickness of the current transmission rubber vibration isolation pad is constant, so its vibration isolation performance and noise reduction ability are also fixed and cannot be adjusted according to actual needs. SUMMARY

[0005] In order to overcome the defect that the traditional rubber vibration isolation pad cannot adjust the noise reduction performance, the present application proposes a vibration isolation type electronic water pump.

[0006] The technical problem to be solved by the present application is solved by the following technical scheme:

[0007] A vibration isolation type electronic water pump, comprising a water pump body and a rubber snap ring sleeved outside the water pump body, a locking control assembly is installed on the upper part of the rubber snap ring; two loading seats are provided below the rubber snap ring; a rotating adjustment assembly connecting the two is provided between each loading seat and the rubber snap ring. The material of the loading seat and the rubber snap ring is rubber. The loading seat and the rubber snap ring constitute the entire rubber shock pad. The locking control assembly is used to tightly clamp the rubber snap ring outside the water pump body. The rotating adjustment assembly is used to adjust the inclination angle of the loading seat and the horizontal plane, facilitating the connection of the loading seat and the specific engine support, i.e. facilitating the installation and arrangement of the electronic water pump on the engine support.

[0008] Preferably, a thickening control assembly is further provided on each loading seat. The thickening control assembly can increase the height of the loading seat, thereby reducing the vibration transmitted by the loading seat to the engine support during the operation of the electronic water pump.

[0009] The upper part of the rubber clasp is provided with two lateral extensions; the locking control assembly is composed of a locking bolt connected with the two lateral extensions and a locking nut installed on the locking bolt. The whole rubber clasp is in C shape. By screwing the locking nut, the locking nut can be matched with the threaded head of the locking bolt to laterally extrude the two lateral extensions, thereby fixing and connecting the rubber clasp with the water pump body.

[0010] The rotary adjusting assembly is composed of an L-shaped shaft installed on each loading seat and a lateral pin; the upper part of the L-shaped shaft is connected with the rubber clasp through a bearing, and the front side of the upper part of the L-shaped shaft is uniformly distributed with insertion holes matched with the lateral pin in the annular direction. By matching the lateral pin with different insertion holes, the loading seat can be fixed at different rotary angle positions, thereby facilitating the arrangement and installation of the whole electronic water pump.

[0011] Preferably, the rubber clasp is installed with a lateral sliding sleeve for slidingly installing the corresponding lateral pin, and each lateral sliding sleeve is installed with an I-shaped spring connected with the lateral pin. The lateral pin and the insertion hole are matched.

[0012] Each loading seat is provided with an embedded groove, and the thickening control assembly is composed of a main control plate slidably located in the embedded groove and a main thickening pad plate hingedly connected with the main control plate. The main control plate and the main thickening pad plate are both made of rubber. The main thickening pad plate can increase the thickness of the loading seat. Under normal circumstances, the main thickening pad plate and the main control plate are located inside the embedded groove. The loading seat is also provided with two threaded holes.

[0013] Preferably, the left and right sides of the main control plate are both provided with a circular shaft part; the sidewall of the embedded groove is provided with a waist-shaped groove slidably matched with the circular shaft part. That is, the main control plate can slide and rotate around the central axis of the circular shaft part.

[0014] Preferably, the front side of the embedded groove is provided with a notched groove communicated to the lower end of the main control plate; the front and back lengths of the notched groove correspond to the thickness of the main control plate. The purpose of the notched groove is to facilitate the 90-degree rotation of the main control plate.

[0015] Each loading seat is installed with two upper sliding sleeves, and each upper sliding sleeve is slidably installed with a vertical bolt; each main thickening pad plate is provided with a penetrating groove, and the penetrating groove is slidably installed with two lower sliding sleeves matched with the vertical bolt. When the main thickening pad plate and the main control plate are slid, the main control plate can be rotated by 90 degrees to abut the rear end surface of the notched groove, and then the main thickening pad plate can be rotated by 90 degrees to abut the loading seat, thereby realizing the virtual thickening of the loading seat. By inserting the vertical bolt into the lower sliding sleeve, the main thickening pad plate in the thickened state can be fixed.

[0016] Two lower sliding sleeves are provided with No. II springs connected with the two lower sliding sleeves; the two lower sliding sleeves are provided with an elliptical block; a round shaft is welded at the center position of the elliptical block, and a knob is welded at the upper end of the round shaft. The round shaft is installed in the inside of the main thickened pad through a bearing. By manually rotating the knob and the elliptical block, and under the elastic force of the spring, the two lower sliding sleeves are controlled to slide relatively or backward, so that the lower sliding sleeve can extend out of the inside of the main thickened pad and can be matched with the vertical bolt.

[0017] The beneficial effects of the present application are:

[0018] 1. The rubber clasp can be tightly and closely installed with the electronic water pump body, so that the rubber clasp and the loading seat can play a certain vibration isolation and noise reduction effect when the electronic water pump works, and the installation and disassembly are convenient.

[0019] 2. The two loading seats have the functions of rotating and adjusting the angle and being fixed, so that the electronic water pump can meet the special arrangement and installation requirements on the engine support.

[0020] 3. By controlling the main thickened pad to be attached to the bottom end of the loading seat in a sliding and rotating manner and being fixed, the thickness of the entire loading seat is thickened in a way, the vibration reduction performance is adjusted, and the noise of the electronic water pump when working is further reduced.

[0021] 4. The overall structure is novel, and the operation is convenient. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0035] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be described more clearly and completely below in conjunction with the accompanying drawings in the embodiments. Of course, the described embodiments are only a part of the present application rather than the whole, and other embodiments obtained by those skilled in the art without creative labor on the basis of the present embodiments are all within the protection scope of the present application.

[0036] As shown in Figure 1 and Figure 2 , a vibration isolation type electronic water pump comprises a water pump body 1 and a rubber snap ring 2 sleeved on the outside of the water pump body 1, and a locking control assembly is mounted on the upper part of the rubber snap ring 2; two loading seats 5 are arranged below the rubber snap ring 2; and a rotating adjustment assembly connecting the two is arranged between each loading seat 5 and the rubber snap ring 2. The materials of the loading seat 5 and the rubber snap ring 2 are both rubber. The loading seat 5 and the rubber snap ring 2 constitute the entire rubber shock pad. The locking control assembly is used for clamping the rubber snap ring 2 on the outside of the water pump body 1. The rotating adjustment assembly is used for adjusting the inclination angle of the loading seat 5 with the horizontal plane, so as to facilitate the connection of the loading seat 5 with a specific engine support, that is, to facilitate the installation and arrangement of the electronic water pump on the engine support.

[0037] As shown in Figure 1 , each loading seat 5 is further provided with a thickening control assembly. The thickening control assembly can increase the height of the loading seat 5, so as to reduce the vibration generated by the electronic water pump when working and transmitted to the engine support through the loading seat 5.

[0038] As shown in Figure 1And Figure 2 As shown in the figure, the upper part of the rubber snap ring 2 is provided with two lateral extensions 2a; the locking control assembly is composed of a locking bolt 3 connected with the two lateral extensions 2a and a locking nut 4 installed on the locking bolt 3. The whole rubber snap ring 2 is C-shaped. By screwing the locking nut 4, the locking nut 4 can be matched with the threaded head of the locking bolt 3 to complete the lateral extrusion of the two lateral extensions 2a, thereby fixing and connecting the rubber snap ring 2 with the water pump body 1.

[0039] As shown in the figure, Figure 1 And Figure 4 The rotary adjusting assembly is composed of an L-shaped shaft 6 installed on each loading seat 5 and a lateral pin 7; the upper part of the L-shaped shaft 6 is connected with the rubber snap ring 2 through a bearing, and the front side of the upper part of the L-shaped shaft 6 is uniformly distributed in the annular direction with a hole 6a matched with the lateral pin 7. The above is the conventional design of the rotatable structure of the loading seat 5 and the L-shaped shaft 6. By matching the lateral pin 7 with different holes 6a, the loading seat 5 can be fixed at different rotary angle positions, thereby facilitating the arrangement and installation of the whole electronic water pump.

[0040] As shown in the figure, Figure 4 The rubber snap ring 2 is installed with a lateral sliding sleeve 8 for slidingly installing the corresponding lateral pin 7, and each lateral sliding sleeve 8 is installed with an I-shaped spring 9 connected with the lateral pin 7. The above is the conventional design of the elastic sliding structure, which facilitates the cooperation of the lateral pin 7 and the hole 6a.

[0041] As shown in the figure, Figure 5 And Figure 6 Each loading seat 5 is provided with an embedded groove 5a, and the thickening control assembly is composed of a main control plate 10 located in the embedded groove 5a and slidable and a main thickening pad 11 hingedly connected with the main control plate 10. The materials of the main control plate 10 and the main thickening pad 11 are both rubber. The above is the conventional design of the sliding structure. The main thickening pad 11 can increase the thickness of the loading seat 5. Under normal circumstances, the main thickening pad 11 and the main control plate 10 are located inside the embedded groove 5a. The loading seat 5 is also provided with two threaded holes.

[0042] As shown in the figure, Figure 3 And Figure 7 As an improved way of the present application, a recessed groove 11b can be provided at the bottom end of the main thickening pad 11, through which the main thickening pad 11 and the main control plate 10 can be manually slid.

[0043] As shown in the figure, Figure 6 And Figure 8As shown, the main control board 10 has a circular shaft portion 10a on both the left and right sides; the side wall of the built-in groove 5a has an oblong groove 5b that slides and is hinged to the circular shaft portion 10a. That is, the main control board 10 can both slide and rotate around the central axis of the circular shaft portion 10a.

[0044] like Figure 8 As shown, the front side of the built-in slot 5a has a notch slot 5c that connects to the lower end of the main control board 10; the front and rear lengths of the notch slot 5c correspond to the thickness of the main control board 10. The purpose of the notch slot 5c is to facilitate the main control board 10 to rotate 90 degrees.

[0045] like Figure 7 , Figure 9 as well as Figure 10 As shown, each loading seat 5 is equipped with two upper sliding sleeves 18, and each upper sliding sleeve 18 is slidably fitted with a vertical pin 12; each main thickened pad 11 is provided with a through groove 11a, and two lower sliding sleeves 13 that can be adapted to the vertical pins 12 are slidably installed in the through groove 11a. When the main thickened pad 11 and the main control board 10 slide, the loading seat 5 can be indirectly thickened by first rotating the main control board 10 90 degrees to fit the rear end face of the notch 5c, and then rotating the main thickened pad 11 90 degrees to abut against the loading seat 5. The main thickened pad 11 in the thickened state can be fixed by the insertion and cooperation of the vertical pins 12 and the lower sliding sleeves 13.

[0046] like Figures 8 to 11 As shown, a No. II spring 14 is provided between the two sliding sleeves 13 and connected to them; each of the two sliding sleeves 13 abuts against an elliptical block 15; a round shaft 16 is welded to the center of the elliptical block 15, and a knob 17 is welded to the upper end of the round shaft 16. The round shaft 16 is mounted inside the main thickened pad 11 via a bearing. By manually rotating the knob 17 and the elliptical block 15, and under the action of the spring force, the two sliding sleeves 13 are controlled to slide relative to each other or backward, so that the sliding sleeves 13 can extend out of the main thickened pad 11 and can cooperate with the vertical pin 12.

[0047] When using it, if a better noise reduction and vibration reduction effect is needed, simply pull the main control board 10 and the main thickened pad 11 forward to the limit position manually, then control the main control board 10 to rotate 90 degrees around the circular shaft 10a until it fits the rear end face of the notch groove 5c, and finally rotate the main thickened pad 11 90 degrees and abut against the lower end of the loading seat 5.

[0048] Furthermore, manually rotate knob 17 and elliptical block 15 90 degrees, causing the two sliding sleeves 13 to slide backwards and extend beyond the main thickened pad 11. Then control the vertical pin 12 to move downwards and engage with the sliding sleeves 13. At this point, the entire loading seat 5 is effectively thickened.

[0049] Finally, according to the installation position of the electronic water pump on the engine support, the rotation angle of the loading seat 5 can be adjusted to a suitable position by rotating, then the lateral pin 7 is inserted into the corresponding insertion hole 6a, and then the electronic water pump is connected and installed on the engine support through the bolt.

[0050] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited to the above-mentioned embodiments, and the above-mentioned embodiments and descriptions in the specification are only the principles of the present application.
