Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and specifically to the arrangement structure of a diesel heating system. Background Technology

[0002] As an independent heating device, automotive diesel heaters primarily address two core needs: firstly, the essential need for traditional gasoline vehicles in frigid regions, and secondly, the industry pain point of significantly reduced driving range in new energy vehicles during winter due to heating requirements. Utilizing the technical principle of "independent fuel combustion + forced heat exchange," it can provide heating for the driver's cabin while parking or driving without starting the vehicle's main engine, and can also be used for engine preheating, effectively improving driving comfort and economy. Currently, diesel heaters are mainly used in the "aftermarket modification" stage. While this retrofit model meets users' immediate heating needs to some extent, it poses serious safety hazards and quality defects. During modification, improper placement can easily lead to carbon monoxide gas from diesel combustion flowing back or leaking into the passenger compartment through gaps, causing personal injury accidents to drivers and passengers. Furthermore, aftermarket modifications can easily damage the vehicle's original structure, compromising the reliability and durability of the vehicle's structure.

[0003] Demand for diesel heaters remains strong, driving the technology to evolve from haphazard "aftermarket modifications" to "original equipment manufacturer (OEM) systems that are safe, compliant, and integrated with the vehicle's thermal management system." The industry urgently needs a solution that considers these aspects from the initial vehicle design stage to fundamentally eliminate safety hazards and ensure perfect integration of the added system with the vehicle's overall performance.

[0029] The embodiments of this utility model will be described below with reference to the accompanying drawings and preferred embodiments. The drawings are for illustrative purposes only and should not be construed as limiting the utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be understood that the preferred embodiments are only for illustrating this utility model and not for limiting the scope of protection of this utility model.

[0030] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0031] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium.

[0032] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0033] This embodiment provides, as follows: Figures 1 to 9 The diagram illustrates the arrangement of a diesel-powered heating system applied to a vehicle. The vehicle includes a frame 01, a floor 02, and a driver's seat 03. The floor 02 is mounted on the frame 01; the driver's seat 03 is mounted on the floor 02. The diesel-powered heating system includes a diesel heater 100, an intake assembly 200, an exhaust assembly 300, a fuel supply assembly 400, and a controller 500. The diesel heater 100 is detachably mounted above the floor 02 and located below the driver's seat 03. The intake assembly 200, exhaust assembly 300, and fuel supply assembly 400 are respectively mounted on the frame 01 and connected to the diesel heater 100. The controller 500 is mounted on the side of the driver's seat 03 and connected to the diesel heater 100. The heater 100 is controlled and connected; the intake assembly 200 includes an air filter 210 and an intake pipe 220. The air filter 210 is mounted on the frame 01 and is connected to the diesel heater 100 through the intake pipe 220; the exhaust assembly 300 includes an exhaust muffler 310 and an exhaust pipe 320. The exhaust muffler 310 is mounted on the frame 01 and is connected to the diesel heater 100 through the exhaust pipe 320; the exhaust outlet of the exhaust pipe 320 faces the rear of the vehicle; the fuel supply assembly 400 includes a fuel tank 410 and a fuel pump 420. The fuel tank 410 is mounted on the frame 01 and is connected to the diesel heater 100 through a fuel pipe 430; the fuel pump 420 is mounted on the fuel pipe 430.

[0034] In this embodiment, the controller 500 is connected not only to the diesel heater 100 but also to the fuel pump 420, so that the occupants can control the fuel pump 420 to circulate fuel through the controller 500, allowing the diesel fuel in the fuel tank 410 to flow into the diesel heater 100 and be atomized. At the same time, the air intake assembly 200 allows filtered air to enter the diesel heater 100, mix with the atomized diesel fuel, and ignite it, generating high temperatures and raising the temperature inside the vehicle's passenger compartment through heat exchange, thus achieving the purpose of heating. The exhaust gas after combustion is discharged towards the rear of the vehicle through the exhaust pipe 320 to prevent exhaust gas from entering the passenger compartment and causing personal safety issues for the occupants. At the same time, the exhaust muffler 310 can silence the exhaust gas and prevent noise pollution.

[0035] This solution designs the installation positions of the diesel heater 100, intake assembly 200, exhaust assembly 300, fuel supply assembly 400, and controller 500 on the vehicle, providing a clear and standardized layout for the installation of the diesel heating system on the vehicle, reducing the assembly difficulty and modification risks of the diesel heating system; at the same time, this solution assembles the diesel heating system without changing the existing vehicle structure layout, which avoids the situation where retrofitted diesel heating systems are prone to damaging the existing vehicle structure, and ensures the comfort of the vehicle when using the diesel heater 100 in cold environments.

[0036] When assembling the diesel-powered heating system of this embodiment into a vehicle, the following precautions should be taken: the air inlet and outlet of the diesel heater 100 should be located at the same ambient temperature to avoid creating a pressure difference within the heater 100 that could affect the exchange of gas between the inside and outside, thus ensuring heating performance; the outlet temperature of the diesel heater 100 is high, so the outlet should not be exposed to prevent burns to occupants. The diesel heater 100 can also be installed under the passenger seat of the vehicle.

[0037] The fuel tank 410 is located on the bottom plate 02 near the rear of the vehicle and behind the rear axle. The fuel filler neck of the fuel tank 410 can be placed on the side of the fuel tank 410 or the opening of the bottom plate 02. To prevent the fuel tank 410 from being collided during vehicle operation, protection can be applied to the fuel tank 410.

[0038] For ease of operation, the controller 500 is located on the left side of the driver's seat 03.

[0039] The oil pump 420 should be adjusted according to the position of the oil tank 410 and located in front of the vehicle's rear shock absorber.

[0040] The air filter 210 should be positioned above the vehicle's battery pack and close to the diesel heater 100.

[0041] like Figure 3As shown, in this embodiment, the frame 01 includes a first longitudinal beam 011, a second longitudinal beam 012, a rear crossbeam 013, a first front crossbeam 014, and a second front crossbeam 015. The first longitudinal beam 011 and the second longitudinal beam 012 are symmetrically arranged. The two ends of the rear crossbeam 013 are respectively installed on the first longitudinal beam 011 and the second longitudinal beam 012, and are close to the rear of the vehicle. The two ends of the first front crossbeam 014 and the second front crossbeam 015 are respectively installed on the first longitudinal beam 011 and the second longitudinal beam 012, and are close to the front of the vehicle. The diesel heater 100 is located between the first front crossbeam 014 and the second front crossbeam 015, and the air filter 210 is installed on the first front crossbeam 014. The first longitudinal beam 011, the second longitudinal beam 012, the rear crossbeam 013, the first front crossbeam 014, and the second front crossbeam 015 form a robust mounting frame, which houses the diesel heater 100 and the air filter 210. This ensures the stability of the diesel heater 100 and the air filter 210, makes full use of the mounting space on the front frame 01 of the vehicle, and clearly defines the mounting positions of the diesel heater 100 and the air filter 210, which is beneficial for parts maintenance.

[0042] When the air filter 210 is installed on the first front crossbeam 014, it should be as close as possible to the diesel heater 100 to reduce the length of the intake pipe 220, thereby reducing the material used in the intake pipe 220 and improving the airflow efficiency.

[0043] like Figure 3 As shown, in this embodiment, the frame 01 further includes a plurality of first reinforcing crossbeams 016 and a plurality of second reinforcing crossbeams 017. Each first reinforcing crossbeam 016 is connected to the first longitudinal beam 011 and the base plate 02 respectively, and is located on the side of the first longitudinal beam 011 away from the rear crossbeam 013 / first front crossbeam 014 / second front crossbeam 015. Each second reinforcing crossbeam 017 is connected to the second longitudinal beam 012 and the base plate 02 respectively, and is located on the side of the second longitudinal beam 012 away from the rear crossbeam 013 / first front crossbeam 014 / second front crossbeam 015. The exhaust muffler 310 is mounted on one of the first reinforcing crossbeams 016. Multiple first reinforcing crossbeams 016 and multiple second reinforcing crossbeams 017 strengthen the connection between the first longitudinal beam 011, the second longitudinal beam 012 and the base plate 02, making the structure of the vehicle base plate 02 stable; at the same time, the first reinforcing crossbeams 016 provide an installation foundation for the muffler, clarify the installation position of the muffler, prevent the muffler installation position from being deviated or not secure, and ensure the accuracy of the muffler installation.

[0044] like Figure 6As shown, in this embodiment, the exhaust assembly 300 also includes a muffler bracket 330, and the exhaust muffler 310 is mounted on a first reinforcing crossbeam 016 via the muffler bracket 330.

The muffler bracket 330 is an L-shaped bracket, with one side plate screwed onto the muffler and the other side plate screwed onto a first reinforcing crossbeam 016 near the superheater (the muffler's exhaust outlet faces the rear of the vehicle).

[0045] like Figure 7 As shown, in this embodiment, the fuel supply assembly 400 further includes a fuel tank bracket 440, and the fuel tank 410 is mounted on the rear crossbeam 013 via the fuel tank bracket 440; fuel tank brackets 440 are installed on both opposite sides of the fuel tank 410. The fuel tank brackets 440 provide a mounting base for the fuel tank 410, and the presence of fuel tank brackets 440 on both sides of the fuel tank 410 allows for multiple mounting points of the fuel tank 410 on the rear crossbeam 013, enhancing the stability of the fuel tank 410 mounted on the rear crossbeam 013.

[0046] like Figure 7 As shown, in this embodiment, the fuel tank bracket 440 includes a main bracket 441 and a secondary bracket 442. The main bracket 441 is connected to the fuel tank 410 through the secondary bracket 442; the main bracket 441 is mounted on the rear crossbeam 013. The secondary bracket 442 connects to the fuel tank 410 and can be installed in a position that suits the shape of the fuel tank 410. The main bracket 441 is used to securely connect to the rear crossbeam 013. The main bracket 441 and the secondary bracket 442 work together to allow the fuel tank 410 to be fitted onto the rear crossbeam 013. The secondary bracket 442 is an L-shaped bracket, with one side plate connected to the fuel tank 410 (welded or integrally formed with the fuel tank 410), and the other side plate screwed onto the main bracket 441. The main bracket 441 is a laterally elongated U-shaped bracket, with both ends mounted on the two rear crossbeams 013 respectively.

[0047] like Figure 3 As shown, in this embodiment, the frame 01 includes two parallel rear crossbeams 013, and the fuel tank bracket 440 is mounted on the two rear crossbeams 013 at both ends. The two rear crossbeams 013 share the weight of the fuel tank 410 through the fuel tank bracket 440, thus distributing the weight of the fuel tank 410 across the different rear crossbeams 013 and improving the stability of the fuel tank 410 mounted on the rear crossbeams 013 through the fuel tank bracket 440.

[0048] like Figure 8As shown, in this embodiment, the oil supply assembly 400 further includes an oil pump bracket 450, which is mounted on the first longitudinal beam 011.

The oil pump 420 is screwed onto the oil pump bracket 450.

[0049] like Figure 9 As shown, in this embodiment, the air intake assembly 200 further includes a filter bracket 230, which is fitted onto the air filter 210 and mounted on the first front crossbeam 014. The filter bracket 230 provides a mounting base for the air filter 210 on the first front crossbeam 014, ensuring the stability of the air filter 210 mounted on the first front crossbeam 014. The filter bracket 230 is an annular assembly with a connecting protrusion extending from the annular joint, which is screwed onto the first front crossbeam 014.

[0050] like Figure 3 As shown, in this embodiment, the frame 01 further includes a central crossbeam 018, with its two ends respectively mounted on the first longitudinal beam 011 and the second longitudinal beam 012. The central crossbeam 018 strengthens the connection between the first longitudinal beam 011 and the second longitudinal beam 012, improving the overall torsional resistance of the frame 01, making the vehicle chassis structure stable, and contributing to the improvement of the frame 01's stability and durability. In this embodiment, two central crossbeams 018 are provided between the first longitudinal beam 011 and the second longitudinal beam 012.

[0051] like Figure 3 As shown, in this embodiment, each of the first reinforcing crossbeams 016 and each of the second reinforcing crossbeams 017 are arranged close to the first front crossbeam 014 / second front crossbeam 015 / middle crossbeam 018.
