[0050] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0051] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "circumferential", "radial", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this utility model 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 of this utility model.

[0052] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0053] As those skilled in the art will understand, the radiator is a core component of a bus heating system, exchanging heat with the air in the cabin through forced convection by a fan. Existing radiators are relatively large, typically a square structure of 250mm × 260mm × 115mm. Furthermore, the cabin's spatial layout prioritizes the needs of essential functional areas such as seat movement aisles and safety equipment, further compressing the radiator's installation space. Therefore, current radiators are usually installed under the seats, placing significant demands on the space beneath the seats. However, some vehicle models, for ergonomic reasons, have seats designed at a low height, resulting in insufficient space under the seats to accommodate the radiator installation, thus affecting the driving and passenger experience.

[0054] Based on this, please refer to Figures 1 to 2 This utility model provides a vehicle frame assembly, including a floor 10 and a radiator 11. The floor 10 has a mounting hole (not shown in the figure) that penetrates the floor 10. The radiator 11 has a housing 110 that passes through the mounting hole. The sidewall of the housing 110 is connected to the floor 10, and a portion of the housing 110 is located below the floor 10. By placing a portion of the housing 110 below the floor 10, the installation space required for the radiator 11 in the height direction within the vehicle cabin is reduced. This eliminates the limitation of insufficient installation space in the vehicle cabin, allowing the radiator 11 to be installed in any unused location. This reduces the difficulty of installing the radiator 11 while ensuring a stable and suitable temperature inside the vehicle, further enhancing the driving and passenger experience.

[0055] Exemplary, the radiator 11 can be installed inside the cockpit, and the floor 10 can be the cockpit floor. Those skilled in the art will understand that the spatial layout of the cockpit typically prioritizes the installation of seat aisles and other equipment, thus further compressing the installation space for the radiator 11. This embodiment, by installing a portion of the radiator 11's housing 110 below the cockpit floor 10, reduces the space required for the radiator 11 within the cockpit, allowing it to be installed in any unused location within the cockpit, further ensuring the comfort of the cockpit environment and enhancing the driver's driving experience.

[0056] The following description uses the case where the radiator 11 is installed in the cockpit as an example to illustrate the installation structure of the radiator 11. This does not mean that the radiator 11 proposed in this embodiment can only be installed in the cockpit. It can be adapted and installed in the passenger compartment or other areas of the vehicle. This embodiment does not limit this.

[0057] Please refer to Figures 2 to 5 The frame assembly also includes a cover 12; the cover 12 is located below the floor 10 and is fixed relative to the floor 10; the cover 12 has an opening that corresponds to a mounting hole; a portion of the housing 110 located below the floor 10 is housed within the cover 12. The cover 12 prevents dust and impurities from the area below the floor 10 from entering the cockpit through the assembly gap between the housing 110 and the floor 10, thus improving the environment inside the cockpit and enhancing driver comfort.

[0058] In this embodiment, please refer to Figure 3 The protective cover 12 can be a box-like structure with four side panels and a bottom plate. The four side panels are distributed and connected sequentially along a direction parallel to the floor 10. The bottom plate is parallel to the floor 10 and is connected to one end of each of the four side panels. The other ends of the four side panels are connected to the floor 10 below. The ends of the four side panels away from the bottom plate form openings, which are positioned corresponding to the mounting holes. After the housing 110 passes through the mounting holes, it can fall directly into the protective cover 12 through the openings.

[0059] Optionally, the cover 12 can also be in other shapes, such as the side plates and bottom plates being curved plates, or partly flat plates and partly curved plates. Of course, for ease of installation, the shape of the cover 12 is preferably a regular shape such as a cuboid, prism, or cylinder, so that installers can install it successfully in one go and improve installation efficiency.

[0060] Please refer to Figures 3 to 5The frame assembly also includes a frame 13; a floor 10 is laid on top of the frame 13; and a cover 12 is installed on the frame 13. The frame 13 serves two purposes: firstly, it supports the floor 10, ensuring its safety and stability; secondly, it provides a connection surface for the cover 12, preventing the cover 12 from directly connecting to the floor 10 and affecting the service life and load-bearing performance of the floor 10.

[0061] Furthermore, the opening of the protective cover 12 is provided with a first protrusion 121 that protrudes outward, and the first protrusion 121 is connected to the bottom of the frame 13. The first protrusion 121 provides a connection surface for the connection between the protective cover 12 and the frame 13, which improves the ease of installation while ensuring the connection strength.

[0062] exist Figure 3 and Figure 4 In the example shown, the first protrusion 121 extends in a direction parallel to the floor 10, and the surface of the first protrusion 121 near the floor 10 forms a welding surface and is welded to the bottom of the frame 13.

[0063] Optionally, the frame 13 is formed by interconnecting multiple crossbeams 131 and multiple longitudinal beams 132, with the crossbeams 131 and longitudinal beams 132 enclosing a mounting frame. The positions of the mounting holes correspond to the positions of the mounting frame. The first protrusion 121 can be respectively provided on the side plates of two opposing protective covers 12, so as to be welded to two adjacent crossbeams 131 or two adjacent longitudinal beams 132 respectively; the first protrusion 121 can also be provided on two interconnected side plates, so as to be welded to the crossbeams 131 and longitudinal beams 132 respectively; the first protrusion 121 can also be provided on the four side plates of the protective cover 12, which is not limited in this embodiment.

[0064] To ensure the connection strength between the first protrusion 121 and the skeleton 13, the first protrusion 121 is preferably a long strip structure to increase the welding area between the first protrusion 121 and the skeleton 13; in other embodiments, the first protrusion 121 may also be a block structure.

[0065] In some embodiments, please refer to Figure 2 The portion of the housing 110 located below the floor 10 accounts for 30% to 50% of the total height of the housing 110. Thus, by placing 30% to 50% of the height of the housing 110 below the floor 10, the space occupied inside the cockpit is reduced, allowing the radiator 11 to be installed anywhere within the cockpit, no longer restricted by insufficient space, further reducing the difficulty of installing the radiator 11.

[0066] For example, the ratio of the height of the portion of the housing 110 located below the floor 10 to the total height of the housing 110 can be 30%, 33%, 38%, 40%, 45%, or 50%.

[0067] As an optional embodiment, please refer to Figure 2 , Figures 6 to 7 The radiator 11 includes a water tank 111 and a water pipe 112; the water tank 111 is located inside the housing 110, and the water pipe 112 is connected to the water tank 111; the housing 110 is provided with a first clearance hole 1101, and the protective cover 12 is provided with a second clearance hole 122, and the water pipe 112 passes through the first clearance hole 1101 and the second clearance hole 122 in sequence.

[0068] In this way, hot water is injected into the water tank 111 through the water pipe 112. On the one hand, it can directly dissipate heat to the cockpit. On the other hand, it can cooperate with the fan 114 to draw the cold air in the cockpit into the radiator 11 and exchange heat with the hot water to ensure that the cockpit is always in a suitable temperature range, thereby improving the driver's comfort.

[0069] Preferably, the first clearance hole 1101 and the second clearance hole 122 can overlap in a direction perpendicular to the floor 10 to improve the ease of installation of the radiator 11, and ensure that the water pipe 112 can extend out of the housing 110 and the cover 12 and connect with other heating components.

[0070] In this embodiment, the radiator 11 is a hydroelectric radiator, and the water tank 111 can be connected to the heater via a water pipe 112. The heater is used to heat the water flowing through the water pipe 112 to ensure the water temperature. The water tank 111 can be a pipe-driven water tank.

[0071] by Figure 6 and Figure 7 For example, the water tank 111 is provided with two water pipes 112. Correspondingly, there are two first clearance holes 1101 and two clearance holes 122, which correspond to the positions of the water pipes 112. In some other embodiments, the number of water pipes 112 can also be set to other reasonable numbers, and the number of first clearance holes 1101 and second clearance holes 122 can also be set accordingly. This embodiment does not limit this.

[0072] Preferred, in Figure 2 In the illustrated example, the frame assembly also includes a first seal 14, which is disposed between the wall of the second clearance hole 122 and the water pipe 112. The first seal 14 increases the sealing performance of the cover 12, reduces the probability of dust and impurities entering the radiator 11 through the second clearance hole 122, and effectively isolates the vehicle from the internal and external environments.

[0073] Optionally, the first seal 14 can be a sealing ring, which can be made of materials such as nitrile rubber, fluororubber, silicone rubber, or fluorosilicone rubber.

[0074] Please continue to refer to this. Figure 6 and Figure 7 The radiator 11 includes a partition 113 and a fan 114. An air intake grille 1102 and an air exhaust grille 1103 are provided on the part of the housing 110 located above the floor 10. The partition 113 and the fan 114 are both located inside the housing 110. One end of the partition 113 is connected to the housing 110 to form an air intake channel 115 and an air exhaust channel 116 inside the housing 110. The fan 114 is connected to the air intake channel 115, and the water tank 111 is located in the air exhaust channel 116. The fan 114 blows air to the water tank 111. The air intake grille 1102 is connected to the air intake channel 115, and the air exhaust grille 1103 is connected to the air exhaust channel 116.

[0075] With this configuration, the partition 113 divides the interior of the shell 110 into an air intake channel 115 and an air outlet channel 116. The fan 114 is connected to the air intake channel 115, and the water tank 111 is located in the air outlet channel 116. The fan 114 creates a negative pressure in the air intake channel 115 to draw cold air from the cockpit into the shell 110 and blow it toward the water tank 111. After exchanging heat with the water tank 111, the air is blown out of the shell 110 through the air outlet channel 116 to heat the cockpit and keep the cockpit temperature within a suitable temperature range.

[0076] In this embodiment, the fan 114 can be an axial flow fan, which includes an impeller, a fan housing, and a guide plate. The impeller and the guide plate are both disposed in the fan housing. The impeller is disposed in the air inlet channel 115. By rotating, it converts mechanical energy into gas kinetic energy to drive the gas into the fan housing. The guide plate is connected to the air outlet channel 116. After the gas enters the fan housing, it enters the air outlet channel 116 through the guiding effect of the guide plate and exchanges heat with the hot water and water vapor in the water tank 111.

[0077] This is an example; please refer to it. Figure 6 and Figure 7 The cross-section of the housing 110 is trapezoidal, and its top surface is an inclined surface. The air intake grille 1102 and the air exhaust grille 1103 are both arranged on the inclined surface so that the hot air blown out of the radiator 11 from the air exhaust grille 1103 can diffuse toward the interior of the cockpit. This arrangement is suitable for areas with no obstruction at the top but with mounting positions for other components on the sides, such as the front bulkhead sealing plate 18, the sub-dashboard 19, and the area near the footrest block 20.

[0078] In other embodiments, if the radiator 11 needs to be installed in a location where the top is covered but the sides are uncovered, such as under the driver's seat, then the air intake grille 1102 and the air exhaust grille 1103 need to be set on the side wall of the housing 110 to ensure the normal operation of the radiator 11.

[0079] Optionally, the housing 110 can be made into a corresponding shape according to the shape of the installation area to adapt to the installation requirements of various different installation positions. For ease of installation, the part of the housing 110 located below the floor 10 can be set into a regular shape, such as a cylinder, prism, frustum, etc., while the part of the housing 110 located above the floor 10 can be set into a regular shape or an irregular shape depending on the installation position. This embodiment does not impose any restrictions on this.

[0080] Please refer to Figure 3 , Figures 6 to 7 The housing 110 has a second protrusion 15 on its side wall, and the frame assembly includes a connector 16; the second protrusion 15 is supported on the floor 10; the second protrusion 15 has a connection hole 150, the connector 16 passes through the connection hole 150 and is embedded in the floor 10.

[0081] Thus, the connection between the housing 110 and the floor 10 is achieved through the cooperation of the second protrusion 15 and the connector 16, which improves the connection strength between the housing 110 and the floor 10, and can evenly distribute the weight of the radiator 11 to the floor 10, thereby improving the service life of the floor 10.

[0082] Furthermore, a second protrusion 15 is provided on the side wall of the housing 110, and the frame assembly includes a second seal 17; both the second protrusion 15 and the second seal 17 are arranged around the outer periphery of the housing 110, and the second seal 17 is located between the second protrusion 15 and the floor 10. The placement of the second seal 17 between the second protrusion 15 and the floor 10 further improves the sealing performance of the floor 10 in the mounting hole area, reducing the probability of external dust and impurities entering the cabin through the mounting gap between the housing 110 and the mounting hole, thus ensuring a clean and hygienic interior environment.

[0083] Exemplary, the second protrusion 15 is arranged circumferentially around the housing 110 and is respectively provided on the four side walls of the housing 110. Each side wall has a plurality of connecting holes 150 on the second protrusion 15. The connector 16 passes through the connecting holes 150 and is embedded in the floor 10 to realize the connection between the housing 110 and the floor 10. In this embodiment, the connector 16 can be a self-tapping screw, and the connecting hole 150 can be a through hole or a threaded hole that matches the connector 16.

[0084] In some other embodiments, the connection between the housing 110 and the floor 10 can also be welding, snap-fit ​​connection, adhesive bonding, etc.

[0085] Optionally, the second seal 17 can be a sealing ring, which can be made of materials such as nitrile rubber, fluororubber, silicone rubber, or fluorosilicone rubber.

[0086] In another embodiment, the present invention also provides a vehicle including the frame assembly described above. Using the frame assembly reduces the installation space required for the radiator 11 in the height direction, eliminating the limitation of insufficient installation space and reducing the difficulty of installing the radiator 11. This allows the radiator 11 to be installed in any unused location, thus improving the driving and passenger experience.

[0087] Please refer to Figure 8 In a preferred embodiment, the frame assembly further includes a front bulkhead sealing plate 18, a sub-dashboard 19, and a footrest block 20; the vehicle includes a driver's compartment and an engine compartment, and the front bulkhead sealing plate 18, sub-dashboard 19, and footrest block 20 are all disposed in the driver's compartment and are all located above the floor 10; relative to the sub-dashboard 19 and footrest block 20, the front bulkhead sealing plate 18 is disposed on the side of the driver's compartment closer to the engine compartment and extends along the width direction of the vehicle; the sub-dashboard 19 and footrest block 20 are spaced apart along the width direction of the vehicle; a mounting area is formed between the front bulkhead sealing plate 18, sub-dashboard 19, and footrest block 20, and mounting holes are opened in the mounting area.

[0088] This configuration, where the radiator 11 is installed in the mounting area between the front bulkhead sealing plate 18, the sub-dashboard 19, and the footrest block 20, avoids interference with the seat passage and safety equipment area. This allows for the installation of the radiator 11 without compromising cockpit safety, thus improving driver comfort. Furthermore, this spatial arrangement meets the minimum space requirements for radiator 11 installation without affecting its normal operation. In addition, its proximity to the driver directly enhances the driver's driving experience.

[0089] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications or equivalent substitutions made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
