Description

Technical Field

[0001] The invention relates to an automobile component, in particular to a vibration-isolating electronic water pump. Background Art

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

[0003] Current research has found that there are three main factors that affect the noise level of electronic water pumps during operation: the first is the vibration caused by the tooth torque of the motor 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 cost-effective to reduce the noise of electronic water pumps by starting with rubber vibration isolation pads.

[0004] Generally speaking, rubber vibration isolation pads are usually placed and installed on the engine bracket, acting as a medium for connecting the electronic water pump and the engine bracket. However, the thickness of the rubber vibration isolation pads currently used in transmissions is constant, so its vibration isolation performance and noise reduction capabilities are also fixed and cannot be adjusted according to actual needs. Summary of the invention

[0005] In order to overcome the defect that the above-mentioned traditional rubber vibration-damping pad cannot adjust the noise reduction performance, the present invention proposes a vibration-isolating electronic water pump.

[0006] The technical problem to be solved by the present invention is achieved by adopting the following technical solutions:

[0007] A vibration-isolating electronic water pump includes a water pump body and a rubber clip sleeved on the outside of the water pump body, a locking control assembly is installed on the upper part of the rubber clip; two loading seats are arranged below the rubber clip; a rotation adjustment assembly is arranged between each loading seat and the rubber clip to connect the two. The loading seat and the rubber clip are both made of rubber. The loading seat and the rubber clip constitute the entire rubber vibration isolation pad. The locking control assembly is used to clamp the rubber clip to the outside of the water pump body. The rotation adjustment assembly is used to adjust the inclination angle of the loading seat and the horizontal plane, so as to facilitate the connection of the loading seat with a specific engine bracket, that is, to facilitate the installation and arrangement of the electronic water pump on the engine bracket.

[0008] Preferably, each loading seat is further provided with a thickening control component, which can variably increase the height of the loading seat, thereby reducing the vibration generated when the electronic water pump is working and is transmitted to the engine bracket through the loading seat.

[0009] The upper part of the rubber clip is provided with two lateral extensions; the locking control assembly is composed of a locking bolt connected to the two lateral extensions and a locking nut installed on the locking bolt. The entire rubber clip is C-shaped. By screwing the locking nut, the locking nut can be matched with the threaded head of the locking bolt to complete the lateral extrusion of the two lateral extensions, thereby fixing the rubber clip to the water pump body.

[0010] The rotation adjustment assembly is composed of an L-shaped shaft and a lateral pin installed on each loading seat; the upper part of the L-shaped shaft is connected to the rubber clamp ring through a bearing, and the front side of the upper part of the L-shaped shaft is evenly distributed along the annular direction with sockets that match the lateral pins. Through the cooperation of the lateral pins and different sockets, the loading seat can be fixed at different rotation angles, thereby facilitating the layout and installation of the entire electronic water pump.

[0011] Preferably, a lateral sliding sleeve for slidingly mounting the corresponding lateral pin is installed on the rubber snap ring, and a spring No. 1 connected to the lateral pin is installed in each lateral sliding sleeve, so as to facilitate the cooperation between the lateral pin and the jack.

[0012] Each loading seat is provided with a built-in slot, and the thickening control assembly is composed of a main control panel that is located in the built-in slot and can slide, and a main thickening pad that is hingedly connected to the main control panel. The main control panel and the main thickening pad are made of rubber. The main thickening pad can increase the thickness of the loading seat in a variable manner. Under normal conditions, the main thickening pad and the main control panel are both located inside the built-in slot. Two threaded holes are also provided on the loading seat.

[0013] Preferably, both left and right sides of the main control board are provided with circular shafts; the side walls of the built-in groove are provided with waist-shaped grooves that slide and hinge with the circular shafts. That is, the main control board can slide and also rotate around the central axis of the circular shaft.

[0014] Preferably, a notch groove connected to the lower end of the main control board is provided on the front side of the built-in groove; the front-to-back length of the notch groove corresponds to the thickness of the main control board. The purpose of the notch groove is to facilitate the main control board to rotate 90 degrees.

[0015] Two upper sliding sleeves are installed on each loading seat, and a vertical latch is slidably installed on each upper sliding sleeve; each main thickening pad is provided with a through slot, and two lower sliding sleeves that can be compatible with the vertical latch are slidably installed in the through slot. When the main thickening pad and the main control board slide forward, the loading seat can be thickened in disguise by first rotating the main control board 90 degrees to fit the rear end surface of the notch slot, and then rotating the main thickening pad 90 degrees to fit the loading seat. The main thickening pad in the thickened state can be fixed by inserting and cooperating with the vertical latch and the lower sleeve.

[0016] A No. II spring connected to the two lower sleeves is provided between them; both lower sleeves are fitted with an elliptical block; a round shaft is welded at the center of the elliptical block, and a knob is welded on the upper end of the round shaft. The round shaft is installed inside the main thickened pad through a bearing. By manually rotating the knob and the elliptical block, and under the action of the spring elastic force, the two lower sleeves are controlled to slide relative to or back to back, so that the lower sleeves can extend out of the main thickened pad and can cooperate with the vertical latch.

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

[0018] 1. The rubber clamp ring can be tightly mounted on the electronic water pump body, so that when the electronic water pump is working, the rubber clamp ring and the loading seat can play a certain role in vibration isolation and noise reduction, and are easy to install and disassemble.

[0019] 2. Both loading seats have the function of rotating and adjusting the angle and fixing, so that the electronic water pump can meet the special layout and installation requirements on the engine bracket.

[0020] 3. By controlling the main thickened pad to slide and rotate and fit to the bottom of the loading seat and fix it, the thickness of the entire loading seat is thickened in disguise, which has adjustable vibration reduction performance and further reduces the noise of the electronic water pump when it is working.

[0021] 4. The overall structure is novel and easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be explained more clearly and completely below in conjunction with the drawings in the embodiments. Of course, the described embodiments are only a part of the present invention but not all of it. Based on this embodiment, other embodiments obtained by those skilled in the art without creative labor are all within the protection scope of the present invention.

[0036] like Figure 1 and Figure 2 As shown, a vibration-isolating electronic water pump includes a water pump body 1 and a rubber clip 2 which is sleeved on the outside of the water pump body 1, and a locking control assembly is installed on the upper part of the rubber clip 2; two loading seats 5 are arranged below the rubber clip 2; and a rotation adjustment assembly is arranged between each loading seat 5 and the rubber clip 2 to connect the two. The loading seat 5 and the rubber clip 2 are both made of rubber. The loading seat 5 and the rubber clip 2 constitute the entire rubber vibration isolation pad. The locking control assembly is used to clamp the rubber clip 2 to the outside of the water pump body 1. The rotation adjustment assembly is used to adjust the inclination angle of the loading seat 5 and the horizontal plane, so as to facilitate the connection of the loading seat 5 with a specific engine bracket, that is, to facilitate the installation and arrangement of the electronic water pump on the engine bracket.

[0037] like Figure 1 As shown, a thickening control component is also provided on each loading seat 5. The thickening control component can variably increase the height of the loading seat 5, thereby reducing the vibration generated by the electronic water pump when it is working and transmitted to the engine bracket through the loading seat 5.

[0038] like Figure 1and Figure 2 As shown, two lateral extensions 2a are provided on the upper part of the rubber clamp 2; the locking control assembly is composed of a locking bolt 3 connected to the two lateral extensions 2a and a locking nut 4 installed on the locking bolt 3. The entire rubber clamp 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 the rubber clamp 2 to the water pump body 1.

[0039] like Figure 1 and Figure 4 As shown, the rotation adjustment assembly is composed of an L-shaped shaft 6 and a lateral pin 7 installed on each loading seat 5; the upper part of the L-shaped shaft 6 is connected to the rubber clamp 2 through a bearing, and the front side of the upper part of the L-shaped shaft 6 is evenly distributed along the annular direction with sockets 6a adapted to the lateral pins 7. The above is a conventional design of the rotatable structure of the loading seat 5 and the L-shaped shaft 6. Through the cooperation of the lateral pins 7 and different sockets 6a, the loading seat 5 can be fixed at different rotation angles, thereby facilitating the arrangement and installation of the entire electronic water pump.

[0040] like Figure 4 As shown, the rubber snap ring 2 is provided with a lateral sliding sleeve 8 for slidingly installing the corresponding lateral pin 7, and each lateral sliding sleeve 8 is provided with a spring 9 connected to the lateral pin 7. The above is a conventional design of the elastic sliding structure, which facilitates the cooperation between the lateral pin 7 and the insertion hole 6a.

[0041] like Figure 5 and Figure 6 As shown, each loading seat 5 is provided with a built-in groove 5a, and the thickening control assembly is composed of a main control board 10 located in the built-in groove 5a and slidable, and a main thickening pad 11 hingedly connected to the main control board 10. The main control board 10 and the main thickening pad 11 are made of rubber. The above is a conventional design of the sliding structure. The main thickening pad 11 can increase the thickness of the loading seat 5 in a variable manner. Under normal conditions, the main thickening pad 11 and the main control board 10 are both located inside the built-in groove 5a. Two threaded holes are also provided on the loading seat 5.

[0042] like Figure 3 and Figure 7 As shown, as an improvement of the present invention, a recessed groove 11b can be provided at the bottom end of the main thickened pad 11, through which the main thickened pad 11 and the main control panel 10 can be conveniently slid manually.

[0043] like Figure 6 as well as Figure 8As shown, the main control board 10 is provided with a circular shaft portion 10a on both sides, and the side wall of the built-in groove 5a is provided with a waist-shaped groove 5b that slides and hinges with the circular shaft portion 10a. That is, the main control board 10 can slide and also rotate around the central axis of the circular shaft portion 10a.

[0044] like Figure 8 As shown, the front side of the built-in groove 5a is provided with a notch groove 5c connected to the lower end of the main control board 10; the front-to-back length of the notch groove 5c corresponds to the thickness of the main control board 10. The purpose of the notch groove 5c is to facilitate the main control board 10 to rotate 90 degrees.

[0045] like Figure 7 , Fig. 9 as well as Fig.10 As shown, two upper sleeves 18 are installed on each loading seat 5, and a vertical pin 12 is slidably installed on each upper sleeve 18; each main thickening pad 11 is provided with a through groove 11a, and two lower sleeves 13 that can be compatible with the vertical pin 12 are slidably installed in the through groove 11a. When the main thickening pad 11 and the main control board 10 slide forward, the main control board 10 can be rotated 90 degrees to fit the rear end surface of the notch groove 5c, and then the main thickening pad 11 is rotated 90 degrees and abuts against the loading seat 5, so that the loading seat 5 can be thickened in disguise. The main thickening pad 11 in the thickened state can be fixed by inserting and matching the vertical pin 12 with the lower sleeve 13.

[0046] like Figures 8 to 11 As shown, a spring No. II 14 connected to the two lower sleeves 13 is provided between the two lower sleeves 13; an elliptical block 15 is abutted against the two lower sleeves 13; a round shaft 16 is welded at the center of the elliptical block 15, and a knob 17 is welded at the upper end of the round shaft 16. The round shaft 16 is installed inside the main thickened pad 11 through a bearing. By manually rotating the knob 17 and the elliptical block 15, and under the action of the spring elastic force, the two lower sleeves 13 are controlled to slide relative to or back to back, so that the lower sleeve 13 can extend out of the main thickened pad 11 and can cooperate with the vertical latch 12.

[0047] During use, when better noise reduction and vibration reduction effects are required, the main control panel 10 and the main thickened pad 11 only need to be manually pulled forward to the extreme position, and then the main control panel 10 is controlled to rotate 90 degrees around the circular axis portion 10a to fit the rear end surface of the notch groove 5c, and finally the main thickened pad 11 is rotated 90 degrees and abuts against the lower end of the loading seat 5.

[0048] Further, the knob 17 and the elliptical block 15 are manually rotated 90 degrees, so that the two lower sleeves 13 slide back and extend out of the main thickened pad 11. Then the vertical latch 12 is controlled to move down and insert into the lower sleeve 13. At this point, the entire loading seat 5 is thickened in disguise.

[0049] Finally, according to the installation position of the electronic water pump on the engine bracket, the rotation angle of the loading seat 5 can be adjusted to the appropriate position by rotating, and then the lateral pin 7 can be inserted into the corresponding socket 6a. Then, the electronic water pump can be connected and installed with the loading seat 5 and the engine bracket by bolts.
