[0002] At present, the cab lifting and flipping industry at home and abroad all use oil pumps as driving components. Oil pumps usually include multiple devices such as manual pumps, electric pumps, and connecting parts. They not only take up a large space and are heavy, but also have a cumbersome and complicated installation process, which puts a burden on the layout design and installation of the vehicle.

[0003] The cab lifting oil tank is usually arranged horizontally, and the manual pump and electric pump are usually arranged separately, which occupies a large area. Figure 1 As shown, the manual pump and the electric pump are fixedly connected by a connecting bracket 12. The manual pump is located on the left side of the connecting bracket 12, and the electric pump is located on the other side of the connecting bracket 12, resulting in a large overall space occupied. The connecting bracket 12 is a steel plate structure and is heavy. In addition, the oil circuits of the manual pump and the electric pump are connected through two connecting oil pipes 13, and both connecting oil pipes 13 are exposed to the outside. Not only are the pipes long and occupy a certain space, but the oil pipes are also affected by the outside world for a long time, and the connection is prone to oil leakage, unreliable connection and other problems.

[0023] The present invention will be further described in detail below in conjunction with specific embodiments so that those skilled in the art can understand the present invention more clearly.

[0024] It should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For ordinary technicians in this field, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0025] Example 1

[0026] This embodiment provides an integrated hydraulic flip combination oil pump, including a manual pump and an electric pump.

[0027] like Figure 2-4 As shown, the manual pump comprises a Z-shaped valve body 1 and an oil tank 4, wherein the oil tank 4 is mounted on an upper portion of one side of the Z-shaped valve body 1, and a first notch is formed on the lower portion of the Z-shaped valve body 1, and the first notch extends to the bottom end of the Z-shaped valve body 1;

[0028] The electric pump includes an electric pump body 3 and a motor 2. The electric pump body 3 is adapted to the first notch and is installed in the first notch. The motor 2 is installed on the side of the electric pump body 3 facing away from the Z-type valve body 1. A second notch is formed on the upper part of the side of the Z-type valve body 1 facing away from the oil tank 4, and the second notch extends to the top of the Z-type valve body 1.

[0029] The Z-type valve body 1 is provided with an oil circuit, which is similar to the base structure of the manual pump in the prior art. For example, the Z-type valve body 1 is provided with two oil circuits, namely, an oil suction line and an oil discharge line, the oil tank 4 is connected to the two oil circuits at the same time, and the electric pump body 3 is also connected to the two oil circuits at the same time, so that the manual pump and the electric pump use the same oil circuit, and the oil circuit is placed inside the Z-type valve body 1.

[0030] In addition, the vertical length of the Z-type valve body 1 is longer than the base in the prior art, so that the lower part of the Z-type valve body 1 can be used to install the electric pump body 3, and its internal space is increased, which is completely sufficient for integrating the oil circuit.

[0031] Based on the above structure, the integrated hydraulic flip combination oil pump provided in this embodiment cancels the connecting bracket 12, and connects the electric pump and the manual pump into one through the Z-type valve body 1. At the same time, the Z-type valve body 1 can also centrally integrate the oil circuit, reduce the overall weight, and make the structure compact. Among them, the oil tank 4 is arranged above the motor 2 and the electric pump body 3, which can raise the oil tank 4 and make full use of the space below the oil tank 4 to reduce the overall footprint. At the same time, the setting of the notch above the Z-type valve body 1 can avoid interference with the outside world and reduce weight, and the setting of the notch below the Z-type valve body 1 can make enough space for the motor 2 and the electric pump body 3, making the overall structure more compact, avoiding the motor 2 from sticking out too much, and improving the effective volume and standardization of the oil tank.

[0032] In addition, if Figure 1 As shown, the two interfaces of the electric pump need to be connected to the manual pump through the connecting oil pipe 13, and in the present application, the oil tank 4 is directly arranged above the electric pump body 3, and the Z-type valve body 1 is in direct contact with the electric pump body 3, so the connection can be achieved by using an extremely short oil pipe, and the oil pipe can be placed inside the Z-type valve body 1, which can not only save space, but also prevent the oil pipe from being affected by the outside world for a long time, causing problems such as oil leakage and unreliable connection.

[0033] In this embodiment, the manual pump also includes conventional components such as a hexagonal rocker shaft 10 and a reversing valve 6. The hexagonal rocker shaft 10 is arranged in the middle of the side of the Z-type valve body 1 facing away from the oil tank 4. The hexagonal rocker shaft 10 passes through the Z-type valve body 1, and its installation structure is similar to the rocker shaft in the prior art. The reversing valve 6 is arranged at the lower part of the side of the Z-type valve body 1 facing away from the oil tank 4, and its installation structure is similar to the reversing handle in the prior art. When the reversing valve 6 is in the lifting state, the cab can be lifted, and when the reversing valve 6 is in the falling state, the cab can be lowered. Two pipe joints 11 are provided at the bottom end of the side wall of the Z-type valve body 1, and the pipe joints 11 are oil outlets, one of which is a T-shaped oil outlet. An air outlet screw 5 is provided at the top of the oil tank 4 for ventilation.

[0034] In this embodiment, the electric pump further comprises a relay 7, which is installed in the first notch, is electrically connected to the motor 2, and is arranged side by side with the electric pump body 3 to further save space. The relay 7 can control the motor 2 to start or stop.

[0035] The electric pump further comprises a vehicle power plug-in 8, and the vehicle power plug-in 8 is electrically connected to the relay 7. That is, the relay 7 can be connected to an external power source through the vehicle power plug-in 8.

[0036] The electric pump further comprises a control button 9, and the control button 9 is electrically connected to the relay 7. The control button 9 can control the on and off of the relay 7.

[0037] In this embodiment, the Z-shaped valve body 1 is an aluminum alloy valve body. The oil tank 4 is an aluminum alloy oil tank. The use of aluminum alloy materials can achieve the purpose of light weight and low processing cost.

[0038] The mechanisms, components and parts not specifically described in the present invention are all existing structures in the prior art and can be directly purchased from the market.
