DETAILED DESCRIPTION

[0038] As mentioned in the background, the performance of electric vehicle batteries in low temperature environments will decrease significantly, and with the advancement of technology and optimization of design, traditional thermal management methods are gradually being canceled or replaced, so the demand for power evaluation of the vehicle electric heater is 2-3 times that of the original vehicle, and water route electric heaters, water pumps, water valves, heat exchangers and other components are added to the vehicle, so it is necessary to integrate the above components while solving the electric heating power, so that the layout space of the vehicle can be reasonably utilized.

[0039] Therefore, the embodiment of the present application integrates the water tank, water pump and heating element on a bracket, reduces the length of the connecting pipeline between each component, optimizes the space layout of the vehicle, reduces the occupied space, and is suitable for electric vehicles with limited space; the integrated design reduces heat loss and improves heating efficiency; the close connection of the water pump and the heating element ensures rapid heating and delivery of water flow; the integrated design simplifies the installation and maintenance process, reduces the complexity and potential failure points of the system; by providing a stable heating environment, the performance of the battery in low temperature environments is not affected, and the overall reliability and user experience of the electric vehicle are improved.

[0040] The exemplary embodiments will be described in detail hereinbelow with reference to the drawings. In the following description, the same reference numerals refer to the same elements throughout the different drawings.

The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0042] Reference Figures 1-2 The embodiment of the present application provides an integrated heating device, which comprises a bracket 100, a water tank 01, a water pump 02 and a heating element 03.

[0043] The bracket 100 is used to be installed on the vehicle body of the motor vehicle.

[0044] The water tank 01 is arranged on the bracket 100, and the water outlet of the water tank 01 is communicated with the water inlet end of the water pump 02.

[0045] The water pump 02 is arranged on the bracket 100, and the water outlet end of the water pump 02 is communicated with the first end of the heating element 03.

[0046] The heating element 03 is arranged on the bracket 100, and the heating element 03 is suitable for heating the water flow from the water pump 02 and delivering the heated water flow to the battery.

[0047] The bracket 100 is used for fixedly mounting the entire heating device on the vehicle body of the motor vehicle, and the bracket is designed in consideration of the spatial layout of the vehicle, and ensures the stability and space utilization of the device. The design of the bracket 100 allows the components to be closely integrated, thereby reducing the occupied space. It should be noted that the water tank 01 can refer to an expansion water tank, which is usually used in a heating system and mainly functions to absorb and relieve the volume expansion of water due to temperature changes. The water outlet of the water pump 02 is in communication with the first end of the heating element 03, thereby ensuring the continuity and stability of the heated water flow. The heating element 03 is arranged on the bracket 100 to provide the necessary heat for the battery to maintain its performance in a low-temperature environment.

[0048] By integrating the water tank 01, the water pump 02 and the heating element 03 on the bracket 100, the length of the connecting pipeline between the components is reduced, the spatial layout of the entire vehicle is optimized, the occupied space is reduced, and the design is suitable for electric vehicles with limited space. The integrated design reduces heat loss and improves heating efficiency. The close connection between the water pump 02 and the heating element 03 ensures rapid heating and delivery of the water flow. The integrated design simplifies the installation and maintenance process, reduces the complexity and potential failure points of the system. By providing a stable heating environment, the performance of the battery in a low-temperature environment is ensured, and the overall reliability and user experience of the electric vehicle are improved.

[0049] In some possible embodiments, the bracket 100 includes a first support 110 and a second support 120 connected to each other.

[0050] The first support 110 and the second support 120 are detachably connected, the first support 110 is used to connect the water tank 01, and the second support 120 is used to connect at least one of the water pump 02 and the heating element 03.

[0051] The bracket 100 is composed of the first support 110 and the second support 120 connected to each other, and the modular design allows flexible installation and disassembly, facilitating maintenance and adjustment. The first support 110 is dedicated to connecting the water tank 01, ensuring stable installation of the water tank 01. Through this connection design, the water tank 01 can be maintained or replaced independently of other components. The design of the second support 120 provides sufficient strength and stability to support the operation of these key components, and the flexible connection mode allows the position and layout of the components to be adjusted according to specific needs.

[0052] It can be known that the detachable connection of the first support 110 and the second support 120 provides the advantage of modular design, so that the components can be installed and maintained independently, improving the maintenance efficiency; by distributing the water tank 01, the water pump 02 and the heating part 03 to different supports, the limited space of the vehicle can be better utilized, and the modular design allows flexible adjustment according to the specific space limit of the vehicle; the independent support and connection of the first support 110 and the second support 120 reduce the influence of vibration and impact on the system, improving the overall reliability and durability of the system; the detachable design simplifies the installation and disassembly process, making the initial installation and subsequent maintenance of the system more convenient.

[0053] In some possible embodiments, the first support 110 includes a bottom plate 111 and a side plate 112, and the first end of the bottom plate 111 is fixedly connected with the second support 120.

[0054] The side plate 112 is fixedly connected with the second end of the bottom plate 111, and the surface of the side plate 112 away from the second support 120 is used to install the water tank 01.

[0055] The design of the bottom plate 111 provides a stable foundation for supporting and fixing the water tank 01; the first end of the bottom plate 111 is fixedly connected with the second support 120, which ensures the stability and integrity of the entire bracket 100 structure, so that the components can work together; the side plate 112 is fixedly connected with the second end of the bottom plate 111, forming an L-shaped structure to provide additional support and fixation for the water tank 01, and the design of the side plate 112 ensures that the water tank 01 can be stably installed on the bracket 100, preventing displacement during vehicle driving; the surface of the side plate 112 away from the second support 120 is used to install the water tank 01, and through this layout, the water tank 01 can be installed using the vertical space of the vehicle.

[0056] It can be known that the combination of the bottom plate 111 and the side plate 112 provides a stable support structure to ensure that the water tank 01 remains stable during vehicle driving, reducing the influence of vibration and impact on the system; by installing the water tank 01 on the side plate 112, the vertical space of the vehicle is fully utilized, reducing the occupation of horizontal space, which is suitable for electric vehicles with limited space; the fixed connection of the first support 110 and the second support 120 provides the advantage of modular design, so that the components can be installed and maintained independently, simplifying the installation and maintenance process of the system; the stable support structure reduces the vibration and impact of the system, improving the overall reliability and durability of the system.

[0057] In some possible embodiments, the first support 110 includes a reinforcing part 113, and the reinforcing part 113 is arranged obliquely.

[0058] The first end of the reinforcing part 113 is fixedly connected with the bottom plate 111, and the second end of the reinforcing part 113 is connected with the surface of the side plate 112 facing the second support 120.

[0059] The design of the reinforcing part 113 aims to enhance the structural strength and stability of the first support 110. The reinforcing part 113 is arranged obliquely to form a triangular support structure. Triangular structures are widely used in engineering to provide additional strength and stability. In structural engineering, a triangle can effectively disperse and transmit the force applied to its vertex. Due to the geometric shape of the triangle, the force applied to one vertex is dispersed to the other two vertices. This force distribution allows the triangle to withstand greater loads without deforming.

[0060] It can be known that the obliquely arranged reinforcing part 113 significantly enhances the overall strength and stability of the bracket by forming a triangular support structure, ensuring that it can withstand various dynamic loads during vehicle driving; the design of the reinforcing part 113 effectively reduces the impact of vibration and impact on the system, improving the reliability and durability of the system, especially in complex road conditions; such design allows the bracket to provide sufficient strength while minimizing the occupation of the vehicle's internal space, providing more space for the arrangement of other components; the design of the reinforcing part 113 is relatively simple, easy to manufacture and install, reducing production costs and installation difficulty.

[0061] In some possible embodiments, the second support 120 includes a support part 121 and a carrying part 122; the first end of the support part 121 is used for fixedly connecting with the vehicle body.

[0062] The carrying part 122 is fixedly connected with the second end of the support part 121, and the carrying part 122 is at least used for carrying the heating element 03.

[0063] The support part 121 provides a stable foundation for the entire heating device by being fixedly connected with the vehicle body, reducing the impact of vibration and impact on the system and improving the reliability of the system; the design of the carrying part 122 allows the heating element 03 to effectively utilize the limited space of the vehicle, reducing interference with other components and optimizing the space utilization of the entire vehicle; the modular design of the second support 120 allows adjustment according to the specific spatial layout of the vehicle, providing greater installation flexibility; by fixing the heating element 03 on the carrying part 122, the installation and maintenance process of the system is simplified, facilitating subsequent maintenance and replacement.

[0064] In some possible embodiments, the carrying part 122 is integrally arranged with the support part 121.

[0065] The integrated design eliminates the weakness of the connection site, improves the strength and durability of the second support 120, ensures that various dynamic loads can be borne during vehicle driving; by reducing the number of components and connection points, the integrated design simplifies the manufacturing and installation process, reduces production cost and installation difficulty; the integrated structure reduces the influence of vibration and impact on the system, improves the reliability and durability of the system; the integrated design enables the support to be more compactly arranged inside the vehicle, reducing interference with other components and optimizing the space utilization of the vehicle.

[0066] As shown in Figures 6-7 In some possible embodiments, a fixing structure is arranged between the bearing part 122 and the first support 110, and the bearing part 122 and the first support 110 are fixedly connected through the fixing structure.

[0067] The use of the fixing structure ensures the firm connection between the bearing part 122 and the first support 110, improves the stability and durability of the entire support system; through the connection of the fixing structure, a more stable overall support system is formed, which can more effectively disperse and bear the load from each component; the fixing structure design allows quick installation and disassembly, simplifying the installation and maintenance process of the system and improving efficiency; through the stable connection, the support system can be more compactly arranged inside the vehicle, reducing interference with other components and optimizing the space utilization of the vehicle.

[0068] In some possible embodiments, the fixing structure is a connecting bolt, the connecting bolt passes through the bearing part 122 and the first support 110, and a nut and a gasket are used to fix the first support 110 and the second support 120 together, and this connection mode is easy to install and disassemble, and is suitable for structures that need to be regularly maintained or replaced.

[0069] The fixing structure can also be a welding seam, which permanently connects two components together by heating and melting the material; welding provides a high-strength connection;

[0070] The fixing structure can also be a buckle structure, which uses buckles or clamps to fix the first support 110 and the second support 120, which is easy to quickly install and disassemble;

[0071] It should be noted that as long as the fixing structure can stably fix the first support 110 and the second support 120 relative to each other, the specific structure of the fixing structure is not limited in the embodiments of the present application.

[0072] In some possible embodiments, the support 100 further comprises a third support 130.

[0073] The second support 120 is used to connect the heating element 03, and the third support 130 is used to connect the water pump 02.

[0074] The third support 130 is used to connect the water pump 02. By providing a dedicated support for the water pump, the installation position of the water pump can be optimized, ensuring its efficient operation and reducing the impact of vibration on other components. By distributing different components to different supports, the support 100 realizes a modular design. This design allows independent installation and maintenance of each component, improving the flexibility and maintainability of the system. The multi-support design allows each component to be optimally installed according to the specific spatial layout of the vehicle, reducing the occupation of the overall space. The independent support of each component reduces interference and vibration between them, improving the overall stability and reliability of the system. The modular support structure makes the installation and maintenance process more convenient, reducing system downtime and maintenance costs.

[0075] It should be noted that the third support 130 can be fixed on the battery frame to make it relative to the vehicle body, providing a stable installation environment for the parts on it.

[0076] In some possible embodiments, the support 100 is used to fix functional modules of the motor vehicle.

[0077] By reusing the support 100, the need for installing multiple independent supports in the vehicle body is reduced, saving space. The material and manufacturing costs are reduced because one support can support multiple functional modules at the same time, reducing the complexity and cost of the overall system. Since multiple functional modules share one support, the installation and maintenance process is more convenient, reducing system downtime and maintenance costs. By integrating multiple functional modules, the support 100 improves the integration of the system, making the vehicle design more compact and efficient.

[0078] As shown in Figure 3 , Figure 5 The support 100 can also fix the thermal management module and the central controller 07. The thermal management module includes the condenser 04, the compressor 05, and the heat exchanger 06. The heat exchanger 06 is fixed on the second support 120, and the central controller 07 is fixed on the third support 130. The compressor 05 is connected to the condenser 04 through a pipeline, and high-pressure high-temperature gaseous refrigerant R134a flows through the pipeline. The condenser is connected to the cab's refrigeration system through a pipeline, and high-pressure medium-temperature liquid refrigerant R134a flows through the pipeline. The cab's refrigeration system is connected to the heat exchanger 06 through a pipeline, and high-pressure medium-temperature liquid refrigerant R134a flows through the pipeline. The cab's refrigeration system is connected to the compressor 05 through a pipeline, and low-temperature low-pressure gaseous refrigerant R134a flows through the pipeline. The heat exchanger 06 is connected to the compressor through a pipeline, and low-temperature low-pressure gaseous refrigerant R134a flows through the pipeline. The heat exchanger 06 can cool the battery.

[0079] R134a (1,1,1,2-tetrafluoroethane) is a commonly used freon refrigerant, widely used in air conditioning, refrigerator and automobile air conditioning system, it is a hydrofluorocarbon (HFC), R134a does not contain chlorine, so it will not destroy the ozone layer; R134a has good thermodynamic performance, suitable for medium temperature application, can provide efficient refrigeration cycle; R134a has good chemical stability, not easy to decompose.

[0080] The support 100 further comprises a fourth support 140 and a fifth support 150, and the compressor 05 is fixed on the fourth support 140.

The above-mentioned pipelines circulate cooling liquid, and the cooling liquid is 50% ethylene glycol + 50% water.

[0082] The three-way valve 08 can be an electromagnetic three-way valve, which is a valve that uses electromagnetic force to control the flow direction of fluid. It usually has three interfaces for inlet, outlet and discharge or switching purposes. The electromagnetic three-way valve has the advantages of fast response speed, simple structure, easy control and maintenance.

[0083] The above-mentioned pipelines can be arranged and adjusted by small pipe clamp supports according to vehicle models, so as to arrange the pipelines concentratedly and reduce space waste.

[0084] As shown in Figures 6-7 , at least one of the first support 110, the second support 120, the third support 130, the fourth support 140 and the fifth support 150 is provided with a counterweight hole 101, which can be used to adjust the weight distribution of the support, thereby improving the balance and stability of the whole device; can effectively reduce the overall weight of the assembly, thereby reducing energy consumption and improving the convenience of operation; can also reduce the amount of material used, thereby reducing manufacturing cost.

[0085] The first support 110, the second support 120, the third support 130, the fourth support 140, and the fifth support 150 can use metal materials such as aluminum alloy, steel, stainless steel, etc., which have good mechanical strength and durability, and are suitable for applications requiring high strength and wear resistance.
