[0012] 1. This application integrates the electric scroll compressor body, water heating and electric heating components, and two-in-one controller into the same structure, breaking the traditional split installation mode, reducing redundant space occupation between components, and achieving a compact layout. At the same time, this application further achieves a three-dimensional compact layout through double-sided installation and base limiting structure, adapting to the limited body space requirements of new energy vehicles. Moreover, this application uses shared housing, connectors and other components, reducing the overall volume by about 30%-40% compared to the split solution, freeing up layout space for battery packs or other key components.

[0013] 2.

Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1-5 As shown, an integrated mechanism for electric compressors and water heaters in new energy vehicles includes a two-in-one controller 2. An electric scroll compressor body 1 and a water heater assembly 3 are respectively installed on both sides of the two-in-one controller 2. The water heater assembly 3 and the electric scroll compressor body 1 are fixedly installed on the two-in-one controller 2 by mounting bolts 4. This application integrates the water heater assembly 3 and the two-in-one controller 2 together through layout integration, sharing a control board, and then combining it with the electric scroll compressor body 1 to form a whole, achieving integration and miniaturization, and reducing vehicle space occupation and vehicle production costs.

[0023] As a further embodiment of this application, the water heating electric heating assembly 3 includes a water circuit box 3.1, a membrane heating assembly 3.2, a heating three-phase terminal block 3.3, and a cover plate 3.4. Specifically, the membrane heating assembly 3.2 is fixedly installed inside the water circuit box 3.1, and is connected to the heating three-phase terminal block 3.3. The cover plate 3.4 and the water circuit box 3.1 are fixedly connected to form a heating cavity. Therefore, in use, the membrane heating assembly 3.2 is a device that uses a thin film material as a heating element. It is used for uniform heating to heat the coolant located inside the water circuit box 3.1. The heating three-phase terminal block 3.3 is connected to a power source to provide heating power to the membrane heating assembly 3.2, thereby achieving the heating effect of the water heating electric heating assembly 3.

[0024] As a further embodiment of this application, the membrane heating assembly 3.2 is replaced with a ceramic heating assembly, wherein the ceramic heating assembly uses PTC (positive temperature coefficient) ceramic, thereby using electrical energy to heat the ceramic, thereby enabling the heating of the coolant inside the water tank 3.1.

[0025] Furthermore, the two-in-one controller 2 includes an electrical control board 2.1, a controller housing 2.2, a high-voltage connector 2.3, and a low-voltage connector 2.4. The electrical control board 2.1 is fixedly installed inside the controller housing 2.2. The electrical control board 2.1 is connected to the high-voltage connector 2.3 and the low-voltage connector 2.4. The high-voltage connector 2.3 and the low-voltage connector 2.4 are used to control the power supply to the electrical control board 2.1. At the same time, the electrical control board 2.1 is used to achieve the combined control of the water heating electric heating component 3 and the electric scroll compressor body 1.

[0026] In the prior art, the compressor controller sends instructions to the membrane heating assembly 3.2, causing the membrane heating assembly 3.2 to heat the liquid in the flow channel of the water tank 3.1. The heat is then transferred to the heated chamber through the liquid flow to meet the heating requirements. In this application, the two-in-one controller 2 integrates a compressor control module to control the heating of the membrane heating assembly 3.2. Therefore, based on the original design, power devices and sensor components related to electric heating are added, and the compressor controller's MCU, high-voltage circuit, communication circuit, and other components are shared. At the same time, the original electric heating housing, high and low voltage connectors, and other parts are reduced, as well as the use and installation space occupied by the vehicle's high and low voltage power input harness. This integration of the two components achieves the goal of cost reduction.

[0027] As a further embodiment of this application, a second base 8 is fixed on the top of the two-in-one controller 2, and a first base 5 is fixed on the top of the water heating and electric heating assembly 3. The first base 5 and the second base 8 are used to cooperate to achieve a fixed connection between the two-in-one controller 2 and the water heating and electric heating assembly 3.

[0028] Specifically, a first limiting base 6 and a third limiting base 11 are fixedly installed on the first base 5, and a second limiting base 9 is fixed on the second base 8. The heights of the first limiting base 6, the second limiting base 9, and the third limiting base 11 are different, which are used to move the second limiting base 9 between the first limiting base 6 and the third limiting base 11 to limit the installation of the second limiting base 9. At the same time, a first limiting hole 7 is opened on the first limiting base 6, a second limiting hole 10 is opened on the second limiting base 9, and a third limiting hole 12 is opened on the third limiting base 11. In use, the limiting bolt 13 passes through the first limiting hole 7 and the second limiting hole 10 and is directly threaded into the third limiting hole 12 to achieve a fixed connection between the first base 5 and the second base 8, and further achieve a fixed connection between the two-in-one controller 2 and the water heating and electric heating component 3.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
