The embodiments described below by referring to the drawings are exemplary and are intended to explain the utility model, and cannot be understood as the limitation of the utility model.

[0046] The suspension pump of the utility model embodiment is described below.

[0047] As Figures 1 to 8 The suspension pump 100 of the utility model embodiment comprises a first motor pump 1, a second motor pump 2 and a controller 3.

[0048] The first motor pump 1 has a first motor shell 11, a first motor, a first pump shell 12 and a first pump, the first motor is arranged in the inner cavity of the first motor shell 11, the first pump shell 12 is connected to one end of the first motor shell 11 in the axial direction, and the first pump is arranged in the first pump shell 12 and connected to the first motor.

[0051] The first motor shell 11, the second motor shell 21 and the controller shell 31 are independent of each other and define respective inner cavities. The first motor shell 11 and the second motor shell 21 are connected. It can be understood that the structures of the first motor shell 11, the second motor shell 21 and the controller shell 31 are separated from each other, each being a relatively complete shell structure and defining a respective inner cavity to accommodate corresponding components, for example, the first motor shell 11 defines a first cavity, the first motor is arranged in the first cavity, the second motor shell 21 defines a second cavity, the second motor is arranged in the second cavity, and the controller shell 31 defines a third cavity, and the electric control component is arranged in the third cavity. Compared with the related art in which multiple partial shells are spliced into a complete shell, the embodiment can relatively separate the components in different shells from each other, avoid interference between the components, improve the stability of the structure and ensure the stability of the product performance.

[0052] For example, when there is interference between the electric control component and the motor during the working process, the embodiment can reduce the interference of the signal and improve the anti-interference ability by arranging the electric control component in the controller shell 31 separately, thereby optimizing the performance of the product.

[0053] In the embodiment, the first motor housing 11 has a first abutting surface 13, the second motor housing 21 has a second abutting surface 23, and the first abutting surface 13 and the second abutting surface 23 abut against each other. The first motor housing 11 and the second motor housing 21 can be fixedly connected together by a connecting member such as a bolt 61, a screw, a buckle, a connecting plate 62, or the like.

[0054] Alternatively, the first abutting surface 13 is located at one end of the first motor housing 11 in the axial direction, the second abutting surface 23 is located at one end of the second motor housing 21 in the axial direction, and the first motor housing 11 and the second motor housing 21 are coaxially arranged.

[0056] Alternatively, the first abutting surface 13 is located at one end of the first motor housing 11 in the axial direction, the second abutting surface 23 is located at one end of the second motor housing 21 in the axial direction, and the first motor housing 11 and the second motor housing 21 are coaxially arranged.

[0057] The motor housing and the controller housing 31 of the suspension pump 100 in the embodiment of the utility model are independent of each other, and can define respective cavities, so that corresponding components can be arranged in the respective cavities, the stability of the respective structures is improved, and when the suspension pump 100 is assembled on a vehicle and faces a complex external environment on a chassis, good performance can be ensured and the failure rate can be reduced.

[0058] Referring to Figures 1 to 4In some embodiments, the controller housing 31 is in abutment with the first motor housing 11 and the second motor housing 21 and is connected by a connecting piece. It can be understood that the controller housing 31 is in abutment with the first motor housing 11 and the second motor housing 21, and then is fixed together by a bolt 61, a screw, a buckle, or the like connecting piece to form a stable integrated structure. At this time, the electric control component can be connected with the first motor and the second motor through a cable, or wirelessly connected through a wireless module, or connected through a plug-in piece.

[0059] Referring to Figure 8 In some embodiments, the controller housing 31 is spaced apart from the first motor housing 11 and the second motor housing 21, and the electric control component is connected with the first motor and the second motor through a cable or wirelessly connected through a wireless signal. It can be understood that the controller housing 31 can be arranged at a certain distance from the first motor housing 11 and the second motor housing 21. When the chassis space is limited, the control layout can be more reasonably planned. The electric control component can be connected with the first motor and the second motor through a cable, of course, wireless connection can also be realized through a wireless module.

[0066] The controller 3 has a controller housing 31 and an electric control component. The controller 3 includes a base 312 and an upper cover 311, and the base 312 and the upper cover 311 are connected and define an inner cavity of the controller 3, and the electric control component is arranged in the inner cavity of the controller 3. The electric control component includes but is not limited to a PCBA board, a cable, a plug, a wireless transmission module and the like. The electric control component is connected with the first motor and the second motor to control the actions of the first motor and the second motor, and then the first motor drives the first pump to act, and the second motor drives the second pump to act.

[0067] In the embodiment, the first motor housing 11 has a first side wall 14 facing the controller 3, the second motor housing 21 has a second side wall 24 facing the controller 3, and the controller housing 31 abuts on the first side wall 14 and the second side wall 24.

[0068] The first electric connection component 41 and the second electric connection component 42 are both plugs, and the number of each is multiple, and the third electric connection component 43 and the fourth electric connection component 44 are both sockets, and the number of each is multiple. When connected, the first electric connection component 41 and the corresponding third electric connection component 43 are plug-connected, and the second electric connection component 42 and the corresponding fourth electric connection component are plug-connected.
