Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to an air reservoir assembly and a vehicle. Background Technology

[0002] Large trucks and buses almost all use air pressure braking systems for braking, and the air tank is an important part of the vehicle's air pressure braking system. It is mainly used to store the gas compressed by the air compressor or air pump and deliver the gas to the braking, horn and other systems.

[0003] There are generally two ways to mount air reservoirs on vehicles: 1) using straps to fix the air reservoir to a bracket, and then connecting the bracket to the vehicle's battery frame; 2) welding the air reservoir to the bracket, and then connecting the bracket to the vehicle's battery frame. Both of these connection methods require brackets, resulting in a larger installation space and increased vehicle weight, which is not conducive to reducing fuel consumption. In addition, under bumpy and harsh operating conditions, the welded joint between the bracket and the air reservoir is prone to breakage, causing dangerous situations such as gas leakage.

[0004] Therefore, there is an urgent need for an air reservoir assembly and vehicle to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide an air tank assembly and vehicle that has a small installation space, is not easy to fall off, and helps to reduce the weight of the whole vehicle and reduce fuel consumption.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A gas storage tank assembly, comprising:

[0008] Battery frame, used to connect the vehicle's chassis;

[0009] An air tank is located below the battery frame;

[0010] The fixing component includes a band, a pad, and a fastener. Two pads are spaced apart along a first direction on the side of the battery frame away from the gas cylinder. The band is clamped to the outside of the gas cylinder, and both ends of the band pass through the battery frame in sequence and are fixed to the corresponding pads by the fasteners.

[0011] As a preferred embodiment of the gas cylinder assembly provided by this utility model, the gas cylinder is a cylindrical structure, and the hoop includes an arc-shaped segment and two connecting segments connected to both ends of the arc-shaped segment. The arc-shaped segment fits against the outer wall of the gas cylinder, and the free ends of the two connecting segments pass through the battery frame and the corresponding pads in sequence and are connected to the corresponding fasteners.

[0012] As a preferred embodiment of the gas cylinder assembly provided by this utility model, the number of gas cylinders is at least two, each of the gas cylinders is arranged side by side along the first direction, and each is fixed to the battery frame by the fixing component;

[0013] The band also includes a straight section, and the arc-shaped sections are arranged one-to-one with the gas storage cylinder. The straight section connects each two adjacent arc-shaped sections, and the two connecting sections are respectively connected to the two arc-shaped sections located at both ends.

[0014] As a preferred embodiment of the gas cylinder assembly provided by this utility model, the pad is provided with a first through hole, the battery frame is provided with a second through hole corresponding to the first through hole, and the end of the hoop passes through the second through hole and the first through hole in sequence and is connected to the fastener.

[0015] As a preferred embodiment of the gas storage cylinder assembly provided by this utility model, both the first through hole and the second through hole are strip-shaped holes extending along the first direction.

[0016] As a preferred embodiment of the gas cylinder assembly provided by this utility model, the pad block is provided with a mating inclined surface on the side away from the battery frame, and the mating inclined surface gradually slopes from the edge of the battery frame to its center towards the direction closer to the battery frame.

[0020] The second direction is perpendicular to the first direction.

[0021] This utility model also provides a vehicle, including a frame and an air tank assembly as described above, wherein the battery frame of the air tank assembly is connected to the frame.

[0022] The beneficial effects of this utility model are:

[0023] The air reservoir assembly provided by this utility model directly fixes the air reservoir to the battery frame through a fixing component, eliminating the need for the bracket structure required in related technologies.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0037] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection or a detachable connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; or the internal communication of two components or the interaction between two components.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0039] like Figures 1-4 As shown, this embodiment provides an air tank assembly, which includes a battery frame 10, an air tank 20, and a fixing component 30. The battery frame 10 is used to connect to the vehicle frame; the air tank 20 is located below the battery frame 10; the fixing component 30 includes a band 31, a pad 32, and a fastener 33. Two pads 32 are spaced apart along a first direction on the side of the battery frame 10 away from the air tank 20. The band 31 is clamped to the outside of the air tank 20, and both ends of the band 31 pass through the battery frame 10 in sequence and are fixed to the corresponding pads 32 by the fasteners 33.

[0040] The air reservoir assembly provided in this embodiment directly fixes the air reservoir 20 to the battery frame 10 via the fixing component 30, eliminating the need for the bracket structure used in related technologies. This simplifies the structure of the air reservoir assembly, reduces installation space, and improves processing and assembly efficiency. It also helps reduce the overall vehicle weight, fuel consumption, and processing costs. Furthermore, it increases the distance between the air reservoir 20 and the ground, improving the vehicle's passability. The pad 32 increases the contact area at the connection point between the fixing component 30 and the battery frame 10, improving the stress distribution on the battery frame 10 and enhancing the fastening effect, thereby preventing the air reservoir 20 from falling off under harsh operating conditions.

[0041] In some embodiments, the battery frame 10 is connected to the vehicle chassis frame by fixing bolts, which has the advantages of simple structure and tight connection.

[0042] In some embodiments, the battery frame 10 is made of composite material, which has the advantages of being lightweight, having excellent mechanical properties, being highly corrosion resistant, and having a long service life.

[0043] It is understood that the battery frame 10 is a rigid structural component used in the prior art for installing, fixing and protecting vehicle batteries, and this embodiment does not limit the specific structure of the battery frame 10.

[0044] For ease of description, such as Figure 1 As shown, the width direction of the battery frame 10 is defined as the first direction, and the length direction of the battery frame 10 is defined as the second direction. The first direction, the second direction, and the height direction of the battery frame 10 are all perpendicular to each other. The gas reservoir 20 is approximately a cylindrical structure, and its axial direction is parallel to the second direction. Figure 1 The direction shown is the actual installation direction of the air tank assembly on the vehicle frame, that is, the battery frame 10 is located above the air tank 20.

[0045] like Figures 5-7 and combined Figure 4 As shown, the pad 32 is provided with a first through hole 321, and the battery frame 10 is provided with a second through hole 101 corresponding to the first through hole 321. The end of the hoop 31 passes through the second through hole 101 and the first through hole 321 in sequence and is connected to the fastener 33 so that the operator can assemble the fixing component 30 and the battery frame 10.

[0046] In some embodiments, both the first through hole 321 and the second through hole 101 are strip-shaped holes extending along a first direction. This design facilitates fine-tuning of the position of the clamp 31 in the first direction when it is connected to the battery frame 10, thereby improving the assembly efficiency of the fixing assembly 30 and the battery frame 10 and enabling a quick connection between the two.

[0047] like Figures 1-4 As shown, the clamp 31 includes an arc-shaped segment 311 and two connecting segments 312 connected to both ends of the arc-shaped segment 311. The arc-shaped segment 311 fits against the outer wall of the air tank 20. The free ends of the two connecting segments 312 pass through the battery frame 10 and the corresponding side pads 32 (specifically the second through hole 101 and the first through hole 321) and are connected to the corresponding fasteners 33. By providing an arc-shaped segment 311 that fits against the outer wall of the air tank 20, the contact area between the clamp 31 and the air tank 20 can be increased, thereby improving the fixing effect of the fixing component 30 on the air tank 20 and preventing the air tank 20 from falling off under harsh operating conditions.

[0048] In some embodiments, the fastener 33 is a fastening nut, and the connecting section 312 has external threads. The fastener 33 is threadedly connected to the free end of the connecting section 312, which has a simple structure and is easy to assemble.

[0049] In some embodiments, a gasket 34 is also provided between the fastener 33 and the pad 32 to improve the fastening effect between the fastener 33 and the band 31.

[0050] In some embodiments, there are at least two gas cylinders 20, each gas cylinder 20 is arranged side by side along a first direction and is fixed to the battery frame 10 by a fixing component 30; the band 31 also includes a straight segment 313, an arc segment 311 is arranged one-to-one with the gas cylinder 20, a straight segment 313 is connected between two adjacent arc segments 311, and two connecting segments 312 are respectively connected to the two arc segments 311 located at both ends.

[0051] In this embodiment, there are two gas storage cylinders 20, which are arranged side by side along the first direction. Correspondingly, there are two arc-shaped segments 311 and one straight segment 313. The two arc-shaped segments 311 are connected by the straight segment 313, and each arc-shaped segment 311 has a connecting segment 312 connected to the end facing away from the straight segment 313. Of course, this embodiment does not limit the specific number of gas storage cylinders 20. The number of gas storage cylinders 20 can also be three, four, five, or even more. The number of arc-shaped segments 311 and straight segments 313 can be adjusted adaptively according to the specific number of gas storage cylinders 20.

[0052] In some embodiments, the band 31 can be directly machined from screw rods, simplifying the processing technology and improving processing efficiency.

[0053] In some embodiments, a protective tube is fitted over the outer portion of the clamp 31. The protective tube serves two purposes: firstly, it increases the contact area between the fixing component 30 and the air reservoir 20, thereby improving the fixing effect of the fixing component 30 on the air reservoir 20; secondly, it provides protection to prevent excessive force between the clamp 31 and the air reservoir 20 from scratching the air reservoir 20. It is understood that the connecting section 312 of the clamp 31 is at least partially exposed through the protective tube to facilitate connection with the fastener 33.

[0054] In some embodiments, the protective tube is made of nylon, which has the advantages of high strength, good toughness and strong wear resistance, and can play a good protective role.

[0055] like Figure 4 and Figure 7 and combined Figure 1 As shown, the pad 32 has a mating inclined surface 323 on the side facing away from the battery frame 10. The mating inclined surface 323 gradually slopes from the edge of the battery frame 10 towards its center. It can be understood that when the outer diameter of the gas cylinder 20 and / or the width of the battery frame 10 changes, the angle between the axial direction of the connecting section 312 of the clamp 31 and the battery frame 10 will also change after the connecting section 312 passes through the second through hole 101 and the first through hole 321. By providing the mating inclined surface 323 on the pad 32, the axial direction of the connecting section 312 can be made perpendicular to the mating inclined surface 323. After the connecting section 312 is connected to the fastener 33, the fastener 33 fits against the mating inclined surface 323, thereby further ensuring the fixing effect between the fixing component 30 and the battery frame 10.

[0056] In some embodiments, the pad 32 is provided with a connecting lug 322, which is detachably connected to the battery frame 10. By providing a detachable connection between the pad 32 and the battery frame 10, the operator can replace the pad 32 with mating inclined surfaces 323 with different inclination angles to adapt to the installation and fixation of air tanks 20 with different outer diameters and / or battery frames 10 with different widths, thereby improving the versatility of the air tank assembly.

[0057] In some embodiments, there are two connecting ears 322, each detachably connected to the battery frame 10 by screws, to improve the connection effect and facilitate disassembly and replacement. Of course, in other embodiments, the number of connecting ears 322 can be one, three, four, etc. This embodiment does not limit this, and designers can make adaptive adjustments to the number of connecting ears 322 according to actual assembly requirements.

[0058] Continue as Figure 1As shown, there are at least two fixing components 30, and each fixing component 30 is spaced apart along the second direction. That is to say, all the gas cylinders 20 are fixed to the battery frame 10 by at least two fixing components 30, which can further improve the fixing effect of the gas cylinders 20, prevent them from falling off during use, and enhance safety.

[0059] This embodiment also provides a vehicle, which includes a frame and the aforementioned air tank assembly, with the battery frame 10 of the air tank assembly connected to the frame. By applying the aforementioned air tank assembly, it is beneficial to reduce the overall vehicle weight, reduce fuel consumption and processing costs, and improve the vehicle's passability. In addition, the air tank 20 has a good fixing effect, which can prevent the air tank 20 from falling off under harsh operating conditions.

[0060] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
