[0026] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] Please refer to the attached Figure 1-2 The embodiment of the present application provides a fixing structure of an expansion water tank 2, which includes an expansion water tank 2 and a connecting bracket, the expansion water tank 2 is connected to the connecting bracket, and the connecting bracket is connected to the vehicle body to assemble the expansion water tank 2 on the vehicle body. In the present application, the connecting bracket is connected to the longitudinal beam 1 or the cross beam (such as the cross beam near the front side of the vehicle, such as the attached Figure 1As shown in the figure, and at least part of it is located outside the longitudinal beam 1 (referring to the side facing the outside of the vehicle body in the width direction of the vehicle body, the same below). If one end of the connecting bracket is connected to the longitudinal beam 1 or the cross beam, and the other end extends to the outside of the longitudinal beam 1 and is connected to the expansion water tank 2, then at least the end of the connecting bracket where the collision water tank is fixed and the expansion water tank 2 are both located outside the longitudinal beam 1. In this way, the position of the expansion water tank 2 can be close to the outside of the vehicle in the width direction of the vehicle body, such as close to the edge of the cab in the width direction of the vehicle body, and is in a position area where it can be filled by hand (the operator can directly insert the filling tap into the expansion water tank 2 without the help of tools).

[0028] In this way, the expansion water tank 2 is fixed to the crossbeam or longitudinal beam 1 of the vehicle chassis. On the one hand, it is no longer restricted by the fixed installation position on the rear suspension of the cab, which makes it easy to adjust the position of the expansion water tank 2 on the vehicle body, and can make the expansion water tank 2 closer to the edge of the vehicle, such as flush with the outer edge of the cab on the width of the vehicle body, so that it can be filled by hand, which effectively improves the convenience of filling, and can also improve the convenience of inspection and maintenance of the expansion water tank 2, and can also avoid layout interference with other components on the inner side of the longitudinal beam 1, thereby improving the convenience of layout; on the other hand, by detachably connecting the connecting bracket to the longitudinal beam 1 or the crossbeam, the expansion water tank 2 and the connecting bracket can form an independent module, which can be independently disassembled and assembled as a whole, thereby improving the convenience of disassembly and assembly and after-sales maintainability.

[0029] The chassis of the vehicle body includes two longitudinal beams 1 and a cross beam located between the two longitudinal beams 1 and arranged along the width direction of the vehicle body. In a preferred embodiment, the connecting bracket is connected to the longitudinal beam 1, so that the expansion water tank 2 can be more conveniently fixed at a position convenient for filling, such as the outer edge of the vehicle, and it is also more convenient to connect and disassemble the connecting bracket and the longitudinal beam 1, so as to facilitate the disassembly, assembly, and maintenance of the expansion water tank 2. Compared with being connected to the cross beam, the connecting bracket can be shorter.

[0030] Specifically, the connecting bracket is connected to the section of the longitudinal beam 1 between the carriage and the cab, so that the expansion water tank 2 is located between the carriage and the cab. In this way, the expansion water tank 2 is located between the carriage and the cab in the length direction of the vehicle body, and is close to the outer edge of the cab in the width direction of the vehicle body, such as being flush with the outer edge of one side of the cab. When filling, the cab and the carriage can be filled without turning over, and it is very convenient for disassembly, assembly, maintenance, etc.

[0031] One end of the connecting bracket is connected to the longitudinal beam 1, and the other end is connected to the expansion tank 2. In some embodiments,

[0032] The connecting bracket includes a first connecting seat 4, a second connecting seat 5 and a connecting member 3. The first connecting seat 4 is connected to the outer side wall of the longitudinal beam 1, the second connecting seat 5 is connected to the outer side wall of the expansion water tank 2, the connecting member 3 connects the first connecting seat 4 and the second connecting seat 5, and the connecting member 3 includes a section arranged along the height direction of the vehicle body and a section arranged along the width direction of the vehicle body. In this way, the expansion water tank 2 and the longitudinal beam 1 have a spacing in both the vehicle body height and the vehicle body length.

In this way, the connector 3 is overall similar to an S-shape, which is easy to process.

[0034] In some embodiments, the connector 3 is an integrally formed tube. The tube system can be bent into a desired structural form, such as the above-mentioned S-shape, which is not only easier to process than welding multiple sections of tubes, but also has higher overall strength. Compared with a solid rod, the connector 3 uses a tube, which can reduce weight while meeting the structural strength requirements, increase the contact area with the two connection seats, and enhance stability.

[0035] The two ends of the connector 3 are connected to the first connector seat 4 and the second connector seat 5, respectively. To facilitate connection, in some embodiments, a positioning docking structure is provided on the first connector seat 4 and / or the second connector seat 5, and the positioning docking structure is configured to locate the connection position of the connector 3. In this way, when assembling the connector 3 and the connector seat, the docking can be quickly performed to locate the connection position, and at the same time, the docking stability of the connector 3 and the connector seat can be enhanced, which is convenient for a stable connection such as welding the connector 3 and the connector seat, thereby enhancing the connection quality and the stability of the connection.

[0036] The positioning docking structure can be a magnetic structure or a plug structure. In a preferred embodiment, the positioning docking structure is a plug structure, and the first connection seat 4 and / or the second connection seat 5 is provided with a docking slot or a docking jack for the end of the connector 3 to be inserted.

[0037] Specifically, the first connection seat 4 includes a first bottom plate connected to the outer side of the longitudinal beam 1, and a docking slot for the end of the connector 3 to be inserted is provided on the first bottom plate. The end of the first section 31 of the connector 3 is inserted into the docking slot in a direction perpendicular to the first bottom plate and fixedly connected to the first bottom plate. For example, the connector 3 is inserted into the first bottom plate and welded to the first bottom plate. In this way, not only can the positioning be fast, the stability during welding is enhanced, but also the connection strength can be enhanced.

[0038] The second connection seat 5 includes a second bottom plate connected to the side wall of the expansion water tank 2, and side plates distributed on both sides of the second bottom plate in the width direction of the vehicle body; the end section 33 of the connection member 3 sequentially penetrates the two side plates and is fixedly connected to at least the two side plates. For example, the end section 33 of the connection member 3 penetrates the first side plate, is inserted into the second side plate, and is welded to the two side plates, and can be further welded to the second bottom plate. The second bottom plate or the side plate can also be provided with a reinforcing rib connected to the end section 33 of the connection member 3.

[0039] In some embodiments, an adjustment structure is provided on the first connection seat 4 and / or the longitudinal beam 1, and the adjustment structure is configured to adjust the position of the expansion water tank 2 in the vehicle body height and vehicle body length direction. In this way, the position of the expansion water tank 2 can be flexibly adjusted according to the vehicle model or specific needs, thereby improving adaptability.

[0040] Specifically, the adjustment structure includes a first connection hole provided on the first connection seat 4 and a second connection hole provided on the longitudinal beam 1. The first connection hole and / or the second connection hole are provided with a plurality of holes or strip holes. The first connection seat 4 and the longitudinal beam 1 are connected by a connecting member such as a bolt that penetrates the first connection hole and the second connection hole. In this way, the installation position is adjusted by setting multiple holes or strip holes, which is not only convenient for processing, but also convenient for multi-position adjustment.

[0041] In some embodiments, a plurality of either the first connection hole or the second connection hole is distributed along the length direction of the longitudinal beam 1 , and a plurality of the other connection hole is distributed along the height direction of the longitudinal beam 1 .

[0042] In some other embodiments, the first connecting hole and / or the second connecting hole may be a strip hole, and the strip hole has a hole segment extending along the length and / or height direction of the longitudinal beam 1, such as the strip hole is a waist hole extending along the length direction of the longitudinal beam 1, or a waist hole extending along the height direction of the longitudinal beam 1, or includes both a hole segment extending along the length direction of the longitudinal beam 1 and a hole segment extending along the height direction of the longitudinal beam 1.
