[0025] See Figure 2-Figure 5 , the utility model provides a technical solution:

[0026] A combined high-pressure pump includes a connecting housing 1, a connecting plate 2, a first drive member 3, a second drive member 4, and a high-pressure pump 5. The high-pressure pump 5 is fixedly mounted on the output portion of each of the first and second drive members 3 and 4. The end of the fixed portion of the first drive member 3 is sealed and fixedly connected to the end of the fixed portion of the second drive member 4. One end of the connecting housing 1 is fixedly connected to the outer wall of the first drive member 3, and the other end of the connecting housing 1 is fixedly connected to the outer wall of the second drive member 4. A first mounting groove 6 is provided on the outer wall of the first drive member 3, and a second mounting groove 7 is provided on the outer wall of the second drive member 4 to cooperate with the first mounting groove 6. One end of the connecting plate 2 is fixedly connected to the first mounting groove 6, and the other end of the connecting plate 2 is fixedly connected to the second mounting groove 7. The first and second drive members 3 and 4 are both conventional motors, and the high-pressure pump 5 is a conventional pump. The connecting housing 1 has two functions: first, to securely connect the first and second drive members 3 and 4; and second, to mount a control board 17, a high-pressure connector 18, and a low-pressure connector 19. The connecting plate 2 is located on a different side from the connecting housing 1. The first mounting groove 6 and the second mounting groove 7 cooperate to install the connecting plate 2. The connecting plate 2 will not protrude after being connected, which facilitates the installation of the entire combined high-pressure pump.

[0027] In some embodiments, two first mounting grooves 6 are provided on the outer wall of the first driving member 3, and two second mounting grooves 7 are provided on the outer wall of the second driving member 4, respectively matching the first mounting grooves 6. The first driving member 3 and the second driving member 4 are connected via two connecting plates 2. The use of the two connecting plates 2 to connect the first driving member 3 and the second driving member 4 makes the connection between the first driving member 3 and the second driving member 4 more stable.

[0028] In some embodiments, a first through hole 8 is provided between the first mounting slots 6, and a second through hole 9 is provided between the second mounting slots 7. A first connecting rod 10 is provided in the first through hole 8 to cooperate with the first through hole 8, and a second connecting rod 11 is provided in the second through hole 9 to cooperate with the second through hole 9. The two ends of the first connecting rod 10 are fixedly connected by one end of the two connecting plates 2, and the two ends of the second connecting rod 11 are fixedly connected by the other end of the two connecting plates 2. The first connecting rod 10 and the second connecting rod 11 are arranged parallel to each other, and the plane in which the first connecting rod 10 and the second connecting rod 11 lie is parallel to the plane in which the connection housing 1 lies. The first connecting rod 10 and the second connecting rod 11 are both arranged on opposite sides of the connection housing 1 and then connected by the two connecting plates 2. This not only makes the connection more stable, but also improves the sealing effect of the first sealing ring 12. The first connecting rod 10 and the second connecting rod 11 are both screws, and can be fixed with nuts at both ends. Alternatively, the first connecting rod 10 and the second connecting rod 11 can be bolts, and one end of the bolts can be fixed with nuts.

[0029] In some embodiments, a first sealing ring 12 is provided between the first driving member 3 and the second driving member 4. A first sealing groove is provided on the end of the first driving member 3 to cooperate with the first sealing ring 12, and a second sealing groove is provided on the end of the second driving member 4 to cooperate with the first sealing ring 12. The first sealing ring 12 is a rubber sealing ring, and the first and second sealing grooves are provided to prevent external water and dust from entering the connection between the first driving member 3 and the second driving member 4.

[0030] In some embodiments, the connecting housing 1 is provided with a third sealing groove, in which a second sealing ring 16 is disposed, which cooperates with the third sealing groove. One end of the second sealing ring 16 cooperates with the first driving member 3, and the other end of the second sealing ring 16 cooperates with the second driving member 4. The first sealing ring 12 is sealed and fixedly connected to the second sealing ring 16. A control board 17 is disposed within the connecting housing 1 to prevent water and dust from entering the connecting housing 1 and thereby preventing damage to the control board.

[0031] In some embodiments, the first driving member 3 and the second driving member 4 are both fixedly connected to the connecting housing 1 via a first screw. The first driving member 3 and the second driving member 4 are both fixedly connected to the connecting plate 2 via a second screw. The connecting housing 1 can be fixed to the first driving member 3 and the second driving member 4 via screws, and the connecting plate 2 can also be fixed to the first driving member 3 and the second driving member 4 via screws, with the ends of the screws not extending into the interior of the first driving member 3 and the second driving member 4.

[0032] In some embodiments, a control board 17 is fixedly mounted within the connection housing 1. A high-voltage connector 18 and a low-voltage connector 19 are sealed and mounted on the connection housing 1. Both the high-voltage connector 18 and the low-voltage connector 19 are electrically connected to the control board 17. Both the high-voltage connector 18 and the low-voltage connector 19 are conventional. The high-voltage connector 18 is used to connect high-voltage electricity, while the low-voltage connector 19 is used to connect low-voltage electricity. Both the high-voltage connector 18 and the low-voltage connector 19 can provide power to the first drive element 3, the second drive element 4, and the control board 17. The control board 17 is used to control the operation of the first and second drive elements 3 and 4.
