Description

TECHNICAL FIELD

[0001] The present application relates to the field of vehicle structure, in particular to a vehicle body structure and a vehicle. BACKGROUND

[0002] In recent years, with the development of new energy vehicles, the update speed of vehicles is getting faster and faster. In order to reduce the design cost of vehicles, more and more attention is paid to the platformization of vehicles in vehicle design.

[0003] CN218299920U discloses a battery integration device and an electric vehicle. The battery integration device includes a vehicle body mechanism, a cooling water pipeline mechanism, a plurality of cooling plates and a plurality of battery modules. The vehicle body mechanism is provided with a battery pack box body. The plurality of battery modules are respectively installed in the battery pack box body. The plurality of cooling plates and the plurality of battery modules are one-to-one corresponding installation. The cooling water pipeline mechanism is arranged between the plurality of battery modules, and the cooling plate is in communication with the cooling water pipeline mechanism.

[0004] However, since the above-mentioned scheme is to fixedly connect the flow passage in the vehicle body structure, the flow passage is cumbersome to disassemble and assemble. UTILITY MODEL CONTENT

[0005] The purpose of the present application is to provide a vehicle body structure and a vehicle, which solves the problem of cumbersome disassembly and assembly of the flow passage.

[0006] In order to achieve the above-mentioned purpose, the technical scheme adopted by the present application is as follows:

[0007] According to the first aspect of the present application, a vehicle body structure is provided, which includes a vehicle body body. The vehicle body body is formed with a flow passage. One end of the flow passage has an inlet, and the other end has an outlet. The flow passage is used for flowing liquid medium.

[0008] According to the above technical means, the liquid medium can enter from the inlet at one end of the flow passage and flow out from the outlet at the other end. The flow passage is formed on the vehicle body body. Through the integrated design of the flow passage and the vehicle body body, the disassembly and assembly steps of the flow passage can be omitted, so that the vehicle assembly is more convenient.

[0009] In one possible implementation, the vehicle body body includes a bottom plate and a flow plate. The flow plate is arranged on the bottom plate and connected with the bottom plate. The flow plate is integrally made with the bottom plate, and the flow plate is provided with the flow passage.

[0010] According to the above technical means, the opening position of the flow passage is arranged in the flow plate by the additionally arranged flow plate. Compared with the flow passage arranged in the bottom plate, the design means that only the flow plate needs to be processed when the flow passage is processed, and the design of the bottom plate does not need to be changed. In addition, the additionally arranged flow plate can provide additional structural support for the vehicle body, thereby improving the stability of the vehicle body.

[0011] In a possible implementation, the number of flow passages is multiple.

[0012] According to the above technical means, on the one hand, more liquid medium can be continuously transported, and the heat exchange efficiency of the heat source is improved. On the other hand, a circulation system can be formed between multiple flow passages. The liquid medium flows into the inlet at one end of a flow passage and flows out of the outlet at the other end. After completing the heat exchange, the liquid medium enters through the inlet at one end of another flow passage and flows out of the outlet at the other end of the other flow passage. In this way, by repeatedly using the same liquid medium, the consumption of the liquid medium is reduced, and the energy consumption and operating cost are reduced.

[0013] In a possible implementation, the number of flow plates is one, and multiple flow passages are arranged on one flow plate.

[0014] According to the above technical means, multiple flow passages are arranged in the same flow plate, which can make the structure more compact and reduce the use of materials, thereby helping to optimize the overall layout of the vehicle body.

[0015] In a possible implementation, the number of flow plates is multiple. One flow passage is arranged on one flow plate.

[0016] According to the above technical means, because only one flow passage is arranged on one flow plate, the flow passages of multiple flow plates can be independent of each other, so when a flow passage fails, the flow passages of other flow plates can still operate normally, thereby improving the reliability and safety of heat exchange. In addition, because the flow passages of each flow plate are independent, the independent flow passages are convenient to maintain.

[0017] In a possible implementation, the number of flow plates is multiple. One flow passage is arranged on one flow plate. The multiple flow plates are located on the same side of the bottom plate and arranged on the bottom plate.

[0018] According to the above technical means, since only one flow channel is formed in one flow plate, the flow channels of the plurality of flow plates can be independent of each other. In addition, since the plurality of flow plates are arranged on the same side of the bottom plate, when the flow channels are maintained, the operator can be on one side of the bottom plate without moving positions on both sides of the bottom plate, so that the flow channels can be conveniently maintained.

[0019] In a possible implementation, the plurality of flow channels extend along a first direction, and the plurality of flow channels are arranged at intervals along a second direction. The first direction intersects the second direction, and both are parallel to the bottom plate.

[0020] According to the above technical means, since the plurality of flow channels extend along the first direction, the flow channels can be connected to different components in the first direction. Since the plurality of flow channels are arranged at intervals along the second direction intersecting the first direction, the plurality of flow channels can be kept at intervals, on the one hand, to make the flow channels independent of each other, and on the other hand, to prevent adjacent flow channels from malfunctioning due to heat concentration. In addition, the plurality of flow channels arranged at intervals along the second direction intersecting the first direction can make the outlets and inlets of the plurality of flow channels arranged at intervals in the second direction, so that the regular arrangement facilitates the connection of the outlets and inlets with other components.

[0021] In a possible implementation, the vehicle body structure further comprises a plurality of connecting joints, and the inlets and outlets are respectively provided with connecting joints.

[0022] According to the above technical means, on the one hand, the connecting joints can facilitate the connection of the flow channels with other components. On the other hand, when a component malfunctions, the connecting joints can be disconnected to isolate the malfunction without affecting the operation of other components.

[0023] In a possible implementation, the flow channel extends along a curved direction.

[0024] According to the above technical means, by extending the flow channel along a curved direction, since the length of the curved flow channel between the same inlet and outlet is greater than that of a straight flow channel, the curved flow channel can increase the heat exchange area of the flow channel.

[0025] In a possible implementation, at least one reinforcing rib is formed on the flow plate.

[0026] According to the above technical means, the reinforcing rib can improve the mechanical strength of the flow plate. At the same time, the reinforcing rib increases the surface area of the flow plate, which helps to improve the heat dissipation efficiency of the flow plate.

[0027] According to the second aspect of the present application, a vehicle is provided, comprising the vehicle body structure of any one of the first aspect.

[0028] It should be noted that the technical effects brought by the vehicle in the second aspect can refer to the technical effects brought by the corresponding implementation modes in the first aspect, which will not be described here.

[0029] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and cannot limit the present application. BRIEF DESCRIPTION OF DRAWINGS

[0031] Figure 2 is a schematic view of a partial structure of a vehicle body provided by an embodiment of the present application.

[0032] In the figure, 1 is a vehicle body; 2 is a flow-through channel; 3 is a cable tie; 4 is a bottom plate; 5 is a flow-through plate; and 6 is a connecting joint. DETAILED DESCRIPTION

[0033] In order for those skilled in the art to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings.

[0034] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. The implementation modes described in the following exemplary embodiments do not represent all implementation modes consistent with the present application. On the contrary, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0035] In recent years, with the popularity of new energy electric vehicles, the updating speed of vehicles is getting faster and faster, and there are more and more vehicle models at different prices. For the traditional vehicle design method, the size, position and mounting method of each structural part of the vehicle body need to be designed uniformly. In order to develop a vehicle body assembly, experienced vehicle body professional designers need to accurately grasp the vehicle body structure layout and block. At the same time, the vehicle performance, collision safety and four processes (stamping, welding, painting and assembly) need to be fully analyzed and verified, and the number of developed parts is large and the cycle is long, which cannot meet the needs of the current rapid updating of vehicles.

[0036] Therefore, the concept of vehicle platformization has been proposed in the field of vehicle structure. Vehicle platformization refers to a method of designing and manufacturing multiple vehicle models using a standardized set of components and architecture. In related technologies, the unibody casting of the lower body section facilitates vehicle platformization and reduces the number of parts in the lower body. The main purpose of vehicle platformization is to improve processing efficiency, reduce costs, and shorten the development cycle of new vehicle models.

[0037] As a crucial component of the vehicle's cooling system, the flow channel is responsible for guiding the flow of liquid media between various parts. However, the aforementioned solution only considers the integrated casting of the vehicle body structure and does not take into account the integrated design of the flow channel, resulting in low integration and limited benefits.

[0038] In traditional circulation channel designs, cable ties with securing functions are typically used to fix the circulation channel to the vehicle body structure, such as... Figure 1 As shown, Figure 1 This is a schematic diagram of a partial structure of a vehicle. The flow channel 2 is secured by fixing holes on the vehicle body 1 and then using cable ties 3 to bypass the flow channel 2 and pass through the fixing holes. However, because this fixing method is performed at a localized location within the flow channel 2, friction and collisions between the flow channel 2 and surrounding components often occur. These collisions may lead to leakage of liquid media, causing vehicle malfunctions. Furthermore, due to the low degree of vehicle platform compatibility with this fixing method, the flow channel 2 needs to be redesigned when the vehicle is updated.

[0039] In existing vehicle platform implementations, related technologies have integrated the configuration of the circulation channel 2 to a certain extent. For example, the circulation channel 2 is installed in the battery pack housing within the vehicle body structure. Alternatively, the circulation channel 2 is designed into the motor tray, which is then fixedly connected to the vehicle body structure. However, these designs all require the circulation channel 2 to be installed into the vehicle body structure, resulting in cumbersome installation and removal of the circulation channel 2.

[0040] To address the cumbersome disassembly and assembly issue of the circulation channel 2, this application provides a vehicle, which can be an electric vehicle, a hybrid vehicle, a solar-powered vehicle, etc., and the specific type of vehicle is not limited here. To achieve the basic functions of the vehicle, it includes components such as a body structure, a power system, and an electrical system.

[0041] A powertrain provides power to a vehicle, enabling it to perform basic driving functions. The composition of the powertrain varies depending on the vehicle type. For example, when the vehicle is an electric vehicle, the powertrain may include a drive motor.

[0042] In order to supply power to electrical components such as the driving motor, the vehicle provided by the embodiments of the present application further comprises a battery system. The battery system can comprise a battery pack which can be used to provide electrical energy. The battery pack can be electrically connected to the electrical components of the vehicle. In this way, the electrical energy of the battery pack can be transmitted to the electrical components of the vehicle for power supply.

[0043] In addition, components such as the driving motor and the battery pack that generate heat during operation are referred to as heat sources, which usually need to be cooled or heated by a cooling system or a thermal management system to keep the heat sources within a safe working temperature range. In order to achieve heat exchange with the heat sources to cool or heat the heat sources, the cooling system or the thermal management system further comprises a liquid supply assembly which can output liquid medium to the outside and exchange heat with the heat sources.

[0044] The vehicle body structure comprises a vehicle body 1, a door and a window. The vehicle body 1 can form the overall shape configuration of the outside of the vehicle. It also forms a passenger space for accommodating passengers. The door can be rotatably connected to the vehicle body 1 and can open or close the internal passenger space. The window can be installed on the door or the vehicle body 1 to facilitate passengers to observe the external environment.

[0045] In addition, the vehicle body 1 is formed with a flow passage 2. One end of the flow passage 2 has an inlet, and the other end has an outlet. The flow passage 2 is used to flow liquid medium.

[0046] In this way, the two ends of the flow passage 2 are connected to the liquid supply assembly and the heat source respectively, and the liquid medium output by the liquid supply assembly enters the flow passage 2 from the inlet at one end and flows out from the outlet at the other end and enters the heat source, thereby achieving heat exchange with the heat source. The flow passage 2 is formed on the vehicle body 1, and through the integrated design of the flow passage 2 and the vehicle body 1, the disassembly step of the flow passage 2 can be omitted, making the vehicle assembly more convenient.

[0047] In one possible implementation, the liquid medium can be cooling liquid.

[0048] In this way, because the temperature of the output cooling liquid is lower than that of the heat source, the liquid medium can cool the heat source when it comes into contact with the heat source, thereby reducing the working temperature of the heat source.

[0049] In one possible implementation, the liquid medium can be heating liquid.

[0050] In this way, because the temperature of the output heating liquid is higher than that of the heat source, the liquid medium can heat the heat source when it comes into contact with the heat source, thereby increasing the working temperature of the heat source.

[0051] In one possible implementation, as shown in Figure 2 , the liquid supply assembly comprises a liquid supply device and a liquid supply pipe. Figure 2A schematic diagram of a partial structure of a vehicle body 1 is provided in the embodiments of the present application. The vehicle body 1 comprises a bottom plate 4 and a flow plate 5. The flow plate 5 is arranged on the bottom plate 4 and connected with the bottom plate 4. The flow plate 5 is integrally formed with the bottom plate 4, as shown in Figure 1 and Figure 2 The flow plate 5 is provided with a flow channel 2.

[0052] In this way, the flow channel 2 is arranged in the flow plate 5. Compared with arranging the flow channel 2 in the bottom plate 4, this design means that only the flow plate 5 needs to be processed when processing the flow channel 2, without changing the design of the bottom plate 4. In addition, the additional flow plate 5 can provide additional structural support for the vehicle body 1, improving the stability of the vehicle body 1.

[0053] For example, the flow plate 5 is integrally formed with the bottom plate 4.

[0054] In another possible implementation, the flow channel 2 can also be arranged in the bottom plate 4.

[0055] In this way, the processing of the flow plate 5 can be omitted, and the surface of the bottom plate 4 has more space to arrange other components because the flow channel 2 is located inside the bottom plate 4 rather than on the surface of the bottom plate 4.

[0056] In one possible implementation, the number of flow channels 2 is multiple.

[0057] In this way, on the one hand, more liquid medium can be continuously transported into the heat source, improving the heat exchange efficiency of the heat source. On the other hand, a circulation system can be formed between the multiple flow channels 2, the liquid supply assembly and the heat source. The liquid medium flows out of the liquid supply assembly, flows into one end of a flow channel 2 through the inlet, flows out of the other end through the outlet, and enters the heat source through the heat exchange inlet to realize heat exchange. The liquid medium after completing heat exchange flows out of the heat exchange outlet of the heat source, enters the other end of the flow channel 2 through the inlet, and flows out of the other end of the flow channel 2 through the outlet and returns to the liquid supply assembly. In this way, by repeatedly using the same liquid medium, the consumption of the liquid medium is reduced, and the energy consumption and operating cost are reduced.

[0058] In one possible implementation, the number of flow channels 2 is one. In this way, only one flow channel 2 is provided, making the design of the flow channel 2 simpler and suitable for simple and short heat exchange requirements, with lower design and processing costs.

[0059] In one possible implementation, the number of flow plates 5 is one, and multiple flow channels 2 are arranged on one flow plate 5.

[0060] In this way, the plurality of flow channels 2 are arranged in the same flow plate 5, so that the structure is more compact, the use of materials is reduced, and the overall layout of the vehicle body 1 is optimized. At the same time, since the plurality of flow channels 2 are arranged, the contact area between the heat source and the liquid medium is increased, so that efficient heat exchange of the heat source can be achieved in a limited space.

[0061] In a possible implementation, the number of flow plates 5 is multiple. One flow channel 2 is arranged on one flow plate 5.

[0062] In this way, since only one flow channel 2 is arranged on one flow plate 5, and the flow channels 2 of the plurality of flow plates 5 can be independent of each other, when a flow channel 2 fails, the flow channels 2 of the other flow plates 5 can still operate normally, improving the reliability and safety of heat exchange. Moreover, since the flow channels 2 of each flow plate 5 are independent, the independent flow channels 2 are convenient to maintain.

[0063] In a possible implementation, the number of flow plates 5 is multiple. A part of the flow plates 5 are arranged with one flow channel 2, and another part of the flow plates 5 are arranged with a plurality of flow channels 2.

[0064] In this way, the flow plates 5 arranged with different numbers of flow channels 2 can adapt to different application scenarios and technical requirements, and provide different doses of liquid medium for different components. The flow plates 5 arranged with a plurality of flow channels 2 are connected to heat sources with high heat exchange requirements, and the flow plates 5 arranged with one flow channel 2 are connected to heat sources with low heat exchange requirements, so as to reduce resource waste.

[0065] In a possible implementation, the number of flow plates 5 is multiple. A plurality of flow channels 2 are arranged on each flow plate 5.

[0066] In this way, since a plurality of flow channels 2 are arranged on each flow plate 5, a large amount of liquid medium can be transported for heat exchange by a large number of flow channels 2, so that the heat exchange effect of the heat source can be further improved.

[0067] In a possible implementation, the number of flow plates 5 is multiple. One flow channel 2 is arranged on one flow plate 5. The plurality of flow plates 5 are arranged on the same side of the bottom plate 4.

[0068] In this way, since only one flow channel 2 is arranged on one flow plate 5, the flow channels 2 of the plurality of flow plates 5 can be independent of each other. In addition, since the plurality of flow plates 5 are arranged on the same side of the bottom plate 4, when the flow channels 2 are maintained, the operator can be only on one side of the bottom plate 4 without moving positions on both sides of the bottom plate 4, so that the flow channels 2 are convenient to maintain.

[0069] Exemplarily, the flow-through plate 5 is arranged on the side of the base plate 4 away from the ground. In this way, the flow-through passage 2 can also be protected from the external environment by the base plate 4.

[0070] In a possible implementation, the number of flow-through plates 5 is multiple. One flow-through passage 2 is arranged on one flow-through plate 5. Part of the multiple flow-through plates 5 is arranged on one side of the base plate 4, and the other part of the flow-through plates 5 is arranged on the other side of the base plate 4. The multiple flow-through plates 5 are arranged on the base plate 4.

[0071] In this way, because one flow-through passage 2 is arranged on each of the multiple flow-through plates 5, each flow-through passage 2 is independent of each other. At the same time, part of the multiple flow-through plates 5 is arranged on one side of the base plate 4, and the other part of the flow-through plates 5 is arranged on the other side of the base plate 4. In this way, the intersection between the part of the flow-through passages 2 arranged on one side of the base plate 4 and the other part of the flow-through passages 2 arranged on the other side of the base plate 4 can be reduced, and the complexity of the arrangement of the flow-through passages 2 is reduced.

[0072] In a possible implementation, the multiple flow-through passages 2 extend along a first direction, and the multiple flow-through passages 2 are arranged at intervals along a second direction. The first direction intersects the second direction, and both are parallel to the base plate 4.

[0073] In this way, because the multiple flow-through passages 2 extend along the first direction, the flow-through passages 2 can be connected to different components in the first direction. Because the multiple flow-through passages 2 are arranged at intervals along the second direction intersecting the first direction, the multiple flow-through passages 2 can be kept at intervals from each other. On the one hand, the flow-through passages 2 can be independently flowed through from each other. On the other hand, the adjacent flow-through passages 2 will not malfunction due to the concentration of heat. In addition, the multiple flow-through passages arranged at intervals along the second direction intersecting the first direction can make the outlets and the inlets of the multiple flow-through passages arranged at intervals in the second direction. In this way, the regular arrangement facilitates the connection of the outlets and the inlets to other components.

[0074] In a possible implementation, as shown in FIG. 1, the vehicle body structure further includes multiple connection joints 6. The inlets and the outlets are respectively provided with the connection joints 6. Figure 2

[0075] In this way, on the one hand, the connection joints 6 can facilitate the connection of the flow-through passages 2 to other components. On the other hand, when a component malfunctions, the connection joints 6 can be disconnected to isolate the malfunction, without affecting the operation of other components.

[0076] In addition, the connection joints 6 can have multiple types. Exemplarily, the connection joints 6 can be straight pipe joints or quick-connect joints. Different types of connection joints 6 can be provided to achieve different functions.

[0077] ​In another possible implementation, the vehicle body structure can also not be provided with the connecting joint 6, and other components are directly connected with the flow passage 2.

[0078] In this way, the possibility of liquid medium leakage caused by loose or poor sealing of the connecting joint 6 is reduced.

[0079] In a possible implementation, the flow passage 2 extends along a curved direction.

[0080] In this way, by extending the flow passage 2 along a curved direction, the curved flow passage 2 can increase the heat dissipation area of the flow passage 2, because the length of the curved flow passage 2 between the same inlet and outlet is greater than that of the straight flow passage.

[0081] In another possible implementation, the flow passage 2 can also extend along a straight direction.

[0082] In this way, compared with the curved flow passage 2, the straight flow passage 2 is simpler to process, and the processing difficulty of the flow passage 2 is reduced.

[0083] In a possible implementation, at least one reinforcing rib is formed on the flow plate 5.

[0084] In this way, the mechanical strength of the flow plate 5 can be improved by arranging the reinforcing rib. At the same time, the surface area of the flow plate 5 is increased by arranging the reinforcing rib, which helps to improve the heat dissipation efficiency of the flow plate 5.

[0085] In another possible implementation, the flow plate 5 can also not be provided with the reinforcing rib.

[0086] In this way, the flow plate 5 without the reinforcing rib is simpler to process.

[0087] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto, any change or replacement within the technical scope disclosed in the present application should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
