Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. It should be noted that, unless otherwise specified, the various features in the embodiments of this application can be combined with each other, and the combined embodiments are still within the protection scope of this application.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this application is in use. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0034] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0035] like Figure 1 and Figure 2 As shown, one aspect of this application provides a multi-system integrated module 100, including an integrated frame 110 for mounting to a vehicle frame 200. The integrated frame 110 includes a support frame 111 and a bottom frame 112, a middle frame 113, and a top frame 114 fixed to the support frame 111 and arranged in layers. A battery 120 and an air tank 130 are fixedly disposed on the bottom frame 112, and the battery 120 and the air tank 130 are arranged along the width direction of the vehicle frame 200. Multiple power batteries 140 are fixedly disposed on the middle frame 113 and the top frame 114, the battery 120 is electrically connected to the power battery 140, and the air tank 130 is connected to the power battery 140 through a pipeline.

[0036] Specifically, the multi-system integration module 100 includes an integrated frame 110, which is fixedly mounted on the vehicle frame 200. The integrated frame 110 includes opposing support frames 111 and a bottom frame 112, a middle frame 113, and a top frame 114 connecting the support frames 111. It should be noted that opposing support frames 111 refer to two or more support frames 111 arranged parallel to each other, with the support rods constituting the support frames 111 corresponding to each other (e.g., top rods corresponding to top rods, side rods corresponding to side rods, and bottom rods corresponding to bottom rods); the bottom frame 112 refers to the layer closest to the vehicle frame 200, the top frame 114 refers to the layer furthest from the vehicle frame 200, and the middle frame 113 refers to the frame located between the bottom frame 112 and the top frame 114. The support frames 111 are fixedly connected to the bottom frame 112, the middle frame 113, and the top frame 114 to form the integrated frame 110. It should be noted that the bottom frame 112, the middle frame 113 and the top frame 114 are parallel to each other and spaced apart from each other. The spaced arrangement and the fixed connection with the support frame 111 form a accommodating space.

[0037] A battery 120 and an air tank 130 are fixedly mounted on the bottom frame 112, and the battery 120 and air tank 130 are placed along the width direction of the frame 200. A power battery 140 is fixedly mounted on the middle frame 113 and the top frame 114, and the power battery 140 placed in the middle frame 113 and the top frame 114 is also placed along the width direction of the frame 200. By integrating the battery 120, air tank 130, and power battery 140 within the integrated frame 110, the overall vehicle structure is more compact, significantly improving the space utilization of the frame 200. Furthermore, this integrated arrangement facilitates the modular design of the frame 200.

[0038] Battery 120 is electrically connected to power battery 140. Power battery 140 charges battery 120 by stepping down the voltage through a converter. When the vehicle is off, battery 120 can power the anti-theft system, key sensing, remote monitoring, and vehicle network; when power battery 140 fails, battery 120 ensures the normal operation of emergency functions (such as hazard warning lights, emergency unlocking, and brake assist); when the vehicle is started, it powers the vehicle's controllers and high-voltage relays, activating power battery 140.

[0039] Air reservoir 130 is connected to power battery 140 via piping. Air reservoir 130 provides a stable pressure source for the pneumatic system by storing compressed air. For example, air reservoir 130 is connected to power battery 140 via a sealing valve and pressure sensor; by injecting compressed air into power battery 140 and monitoring pressure changes, it can determine if there is a leak in power battery 140. Air reservoir 130 is also connected to braking system via piping to provide the air pressure required for braking and enhance braking force. Furthermore, air reservoir 130 is connected to air suspension system via piping for adjusting vehicle height.

[0040] The power battery 140, as a core component of the vehicle, stores high-voltage direct current by connecting to an external power source. This direct current drives the electric motor, replacing the engine in a traditional gasoline-powered vehicle. Additionally, the power battery 140 can also power the high-voltage components of the air conditioning compressor and converter.

[0041] It should be noted that a basic frame is formed by connecting support rods end to end sequentially. Inside the basic frame, a support frame 111 is formed by adding vertical and horizontal reinforcing rods 1111. There is a gap between the top layer frame 114 and the top of the support frame 111, that is, the top layer frame 114 is positioned lower than the top of the support frame 111, so that the power battery 140 can be placed in the receiving space formed by the top layer frame 114 and the support frame 111, without being exposed outside the support frame 111.

[0042] In some implementations, the battery 120 can be a lead-acid battery 120 or a lithium-ion battery 120, and the specific type is not limited.

[0043] In some implementations, the power battery 140 can be a lithium iron phosphate battery or a ternary lithium battery, and the specific type is not limited.

[0044] Optionally, such as Figure 3 As shown, the multi-system integration module 100 also includes a battery base 121. The battery base 121 includes a base plate 1211 fixed to the bottom frame 112 and multiple side plates fixedly connected to the periphery of the base plate 1211. The multiple side plates are spliced ​​end to end to form a receiving cavity with an opening at the top. The battery 120 is fixedly installed in the receiving cavity. The height of the receiving cavity gradually decreases from the center of the frame 200 to the side of the vehicle.

[0045] Specifically, the battery 120 is fixedly installed inside the battery base 121. By fixing the battery base 121 to the bottom frame 112, the battery 120 is fixedly installed inside the integrated frame 110. The battery base 121 includes a base plate 1211 and four side plates surrounding the base plate 1211, thereby forming a receiving cavity for accommodating the battery 120.

[0046] The base plate 1211 of the battery base 121 is fixedly mounted on the bottom frame 112. The first side plate 1212 and the second side plate 1213 of the battery base 121 are fixedly mounted on the reinforcing rod 1111 of the integrated frame 110. The first side plate 1212 and the second side plate 1213 are trapezoidal structures. The third side plate 1214 is connected to the long side of the trapezoidal structure, and the fourth side plate 1215 is connected to the short side of the trapezoidal structure. Therefore, the third side plate 1214 is higher than the fourth side plate 1215. The third side plate 1214 is placed at the center of the bottom frame 112, and the fourth side plate 1215 is placed at the edge of the bottom side plate along the width direction of the frame 200. The structure and placement of the battery base 121 facilitate the inspection and maintenance of the battery 120, and also facilitate the electrical connection of the battery 120 with other components.

[0047] Optionally, such as Figure 4 As shown, the multi-system integration module 100 also includes a gas cylinder support 131; the gas cylinder support 131 includes a first fixing plate 1311, a second fixing plate 1312 and a third fixing plate 1313; the surface of the first fixing plate 1311 is attached to and fixedly connected to the bottom frame 112, the first fixing plate 1311 and the second fixing plate 1312 are perpendicular to each other and fixedly connected, the third fixing plate 1313 is attached to and fixedly connected to the surface of the second fixing plate 1312, and the third fixing plate 1313 is fixedly connected to the gas cylinder 130.

[0048] Specifically, the air cylinder 130 is fixedly mounted on the bottom frame 112 via an air cylinder bracket 131, with the air cylinder 130 located on one side of the bottom frame 112 along the width direction of the vehicle frame 200. The air cylinder bracket 131 is attached to and fixedly connected to the bottom frame 112 via the surface of the first fixing plate 1311, making the connection between the air cylinder bracket and the bottom frame 112 more secure. The second fixing plate 1312 is fixedly mounted to the first fixing plate 1311 and perpendicular to each other, used to raise the air cylinder 130. The third fixing plate 1313 is fixedly connected to the second fixing plate 1312, and the side closest to the air cylinder 130 is curved to facilitate support for the air cylinder 130.

[0049] In some embodiments, there are at least two sets of gas cylinder supports 131, which are used to fix the head and tail of the gas cylinder 130 respectively.

[0050] Optionally, such as Figure 1 As shown, a liquid thermal PTC150 is installed on the bottom frame 112. The liquid thermal PTC150 is located between the battery 120 and the gas storage tank 130 and is connected to the power battery 140.

[0051] Specifically, the liquid-thermal PTC150 (Positive Temperature Coefficient) heats the coolant, which then flows through pipes to the power battery 140, thus controlling the temperature of the power battery 140. Furthermore, the liquid-thermal PTC150 is directly powered by the power battery 140. The liquid-thermal PTC150 is placed in the bottom frame 112, while the power battery 140 is placed in the middle frame 113 and the top frame 114, placing the liquid-thermal PTC150 at the bottom of the power battery 140. Since the bottom of the battery is typically the coldest area at low temperatures, placing the liquid-thermal PTC150 at the bottom prioritizes heating the coldest region, avoiding excessively long heat transfer paths and shortening the heating time. Additionally, in the event of coolant leakage, the bottom placement prevents liquid from dripping directly onto electrical components.

[0052] Optionally, such as Figure 5 As shown, the multi-system integration module 100 also includes a liquid thermal PTC bracket 151; the liquid thermal PTC bracket 151 includes a support portion 1511 with a through groove and a connecting portion 1512 fixedly connected to the opposite side of the support portion 1511, the liquid thermal PTC 150 is fixed to the side of the support portion 1511 away from the through groove, and the connecting portion 1512 is fixedly connected to the bottom frame 112.

[0053] Specifically, the liquid thermal PTC 150 is fixedly connected to the bottom frame 112 via a liquid thermal PTC bracket 151. The liquid thermal PTC bracket 151 is attached and fixedly connected to the bottom frame 112 via a connecting part 1512. The liquid thermal PTC 150 is fixed by a support part 1511 with a through groove, creating a gap between the liquid thermal PTC 150 and the bottom frame 112. The through groove allows gas to pass through the bottom of the liquid thermal PTC 150, more efficiently removing the heat generated by the liquid thermal PTC 150 and preventing heat accumulation on the surface of the liquid thermal PTC 150, thereby reducing the failure rate of the liquid thermal PTC 150.

[0054] Optionally, such as Figure 6 As shown, the multi-system integration module 100 also includes a skin 160, which is disposed on the periphery of the integrated frame 110.

[0055] Specifically, the skin 160 includes an outer peripheral surface 1601 and a fifth side plate 1602 and a sixth side plate 1603 fixedly connected to the outer peripheral surface 1601. The outer peripheral surface 1601 is located around the integrated frame 110, and the skin 160 is fixedly connected to the support frame 111 via the fifth side plate 1602 and the sixth side plate 1603. The skin 160 can prevent rain, snow, or flying stones from damaging the battery 120, the gas tank 130, the liquid thermal PTC 150, and the power battery 140 housed within the integrated frame 110.

[0056] It should be noted that there is a gap between the top of the integrated frame 110 and the skin 160, and the fifth side plate 1602 and the sixth side plate 1603 only cover the two sides of the supporting frame 111. This arrangement allows the gap between the skin 160 and the integrated frame 110 to form a natural ventilation channel and prevent heat accumulation.

[0057] Optionally, such as Figure 6 As shown, the skin 160 is provided with a first inspection door 161 and a second inspection door 162. The first inspection door 161 corresponds to the position of the battery 120, and the second inspection door 162 corresponds to the position of the air tank 130.

[0058] Specifically, by setting a first inspection door 161 and a second inspection door 162 on the skin 160, it is convenient to inspect and maintain the battery 120 and the air tank 130. At the same time, it is also convenient to observe the specific working status of the battery 120, the air tank 130, the liquid thermal PTC 150 and the power battery 140 inside the integrated frame 110, thus avoiding the cumbersome operation of disassembling the skin 160 for inspection and maintenance.

[0059] In some embodiments, the first access door 161 and the second access door 162 can be connected to the skin 160 by a hinge or a hinge connection, which is not limited here.

[0060] Optionally, such as Figure 7 As shown, a charging socket 170 is provided on the side of the bottom frame 112 away from the battery 120, and the charging socket 170 is electrically connected to the power battery 140.

[0061] Specifically, a charging socket 170 is provided on the side of the bottom frame 112 near the vehicle frame 200 and at the end near the battery 120. The charging socket 170 is used to charge the power battery 140 by connecting to an external power source. To prevent rainwater, dust, and other external debris from entering the charging socket 170 and causing risks such as short circuits and leakage, a sealed box 171 is also provided outside the charging socket 170. The sealed box 171 improves the safety, reliability, and durability of the charging system.

[0062] In some implementations, the charging socket 170 can be a dual-gun charging socket 170 or a single-gun charging socket 170, and no limitation is made here.

[0063] Optionally, such as Figure 2 , Figure 7 and Figure 8As shown, the integrated frame 110 includes two opposing support frames 111, which are fixedly connected by a bottom frame 112, a middle frame 113, and a top frame 114. The multi-system integrated module 100 also includes a motor cooling expansion box 190 and a battery cooling expansion box 180, which are respectively fixed to the top of one support frame 111. The motor cooling expansion box 190 is fixed to the top of one support frame 111 by a vertical bracket 1912, and the vertical bracket 1912 is fixedly connected to the top of the other support frame 111 by a diagonal bracket 1913.

[0064] Specifically, the battery cooling expansion box 180 is fixedly mounted on the top of the support frame 111 via a battery cooling expansion box bracket 181. The motor cooling expansion box 190 is fixedly mounted on the top of the support frame 111 via a motor cooling expansion box bracket 191. The motor cooling expansion box bracket 191 includes an expansion box base 1911, a vertical bracket 1912, an inclined bracket 1913, and a Z-shaped connecting seat 1914. The expansion box base 1911 is fixedly mounted on one support frame 111. One end of the vertical bracket 1912 is fixed to the expansion box base 1911, and the other end is used to fix the motor cooling expansion box 190. One end of the inclined bracket 1913 is fixedly connected to the vertical bracket 1912, and the other end is fixedly mounted on the Z-shaped connecting seat 1914. The Z-shaped connecting seat 1914 is fixedly mounted on another support frame 111.

[0065] The motor cooling expansion tank 190 is connected to the motor liquid cooling PTC via piping. The battery cooling expansion tank 180 is connected to the liquid cooling PTC 150 via piping. The motor cooling expansion tank 190 is used to maintain the balance of the motor liquid cooling system, and the battery cooling expansion tank 180 is used to maintain the balance of the battery liquid cooling system. The motor cooling expansion tank 190 and the battery cooling expansion tank 180 balance the system pressure by accommodating the volume expansion of the coolant due to temperature changes, while replenishing the coolant lost due to evaporation or leakage to maintain a stable liquid level. In addition, thanks to their high-level installation, they can effectively remove air bubbles in the circuit to prevent air lock. Together with the liquid level sensor and pressure valve, they achieve status monitoring and overpressure protection, thereby ensuring the cooling efficiency and operational safety of the motor or battery under high-frequency dynamic loads.

[0066] The motor cooling expansion tank 190 is securely mounted on top of the integrated frame 110 via the motor cooling expansion tank bracket 191. This arrangement also allows air bubbles within the system to rise naturally and collect in the motor cooling expansion tank 190, which is then discharged to the outside through the vent (or pressure valve) inside the tank. This ensures smooth flow of coolant in the pipeline and prevents cooling failure due to air resistance. The battery cooling expansion tank 180, mounted on top of the support frame 111, offers the same advantages.

[0067] In some embodiments, the motor cooling expansion box 190 and the battery cooling expansion box 180 are fixedly mounted on the top of the support frame 111 near the cab or on the top of the support frame 111 near the rear of the vehicle, and this is not limited to these embodiments.

[0068] like Figure 7 and Figure 9 As shown, in another aspect of the embodiments of this application, a vehicle is provided, including a frame 200 and a multi-system integration module 100 located behind the vehicle cab. The multi-system integration module 100 is connected to the frame 200 via a connector 210.

[0069] Specifically, the connector 210 includes a first connector 2101, a second connector 2102, a connecting plate 2103, and a reinforcing plate 2104. One end of the first connector 2101 is fixed to the side of the bottom frame 112 near the vehicle frame 200, and the other end is fixed to the reinforcing plate 2104. One end of the second connector 2102 is fixed to the side of the bottom frame 112 near the vehicle frame 200, and the other end passes through a notch above the connecting plate 2103 and is fixedly connected to the reinforcing plate 2104. The connecting plate 2103 is fixedly connected to the reinforcing plate 2104 via wing plates located on both sides of the notch, and another portion of the plate surface is fixedly connected to the vehicle frame 200. The connecting plate 2103 is fixedly disposed on the outer side of the vehicle frame 200 along its width. This connection method ensures a stable connection between the multi-system integration module 100 and the vehicle frame 200.

[0070] In some embodiments, at least two pairs of connectors 210 are included, which are arranged opposite each other along the length of the frame 200.
