Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle cooling or ventilation equipment, and particularly relates to a pipeline fixing structure for an automobile heater box. Background Technique

[0002] The air conditioning system of an automobile includes a heater box. A heater water tank is arranged in the heater box. The water inlet and outlet of the heater water tank extend outside the shell of the heater box through pipelines and are fixed to form a hot water interface. The hot water interface is connected to the heating system or the engine cooling system of the automobile through a water pipe, so as to introduce circulating hot water into the heater water tank. The heater water tank transfers heat to the air flow through a heat exchanger, so that the heater box realizes the supply of warm air in the vehicle.

[0003] During the development of an automobile, generally, some interchangeable parts are designed based on similar vehicle models to reduce the development and manufacturing costs. However, even in various similar vehicle models, there are certain differences in the space for pipelines to pass through and the positions for pipeline connections. The positions of the hot water interfaces on the existing heater boxes are mostly fixed and non-adjustable. As shown in Figure 1 and Figure 2 The existing heater box integrally forms a mounting base 7 on its upper shell 11 or lower shell 12. The pipeline 4 connected to the heater water tank is clamped and fixed through the mounting base 7 and a fixing block 33 that cooperates with the mounting base, so that the end of the pipeline forms a hot water interface 8. This makes it difficult for similar vehicle models to share the heater box. Even if only the upper shell or lower shell with the mounting base is remolded, and then the position of the hot water interface on the heater box is changed, its development cost is relatively high and the development cycle is relatively long. Therefore, it is necessary to design a pipeline fixing structure for an automobile heater box that can conveniently adjust the position of the hot water interface to improve the versatility of the automobile heater box and reduce the development and manufacturing costs. Summary of the Invention

[0004] Aiming at the above-mentioned deficiencies of the prior art, the purpose of the utility model is to provide a pipeline fixing structure for an automobile heater box, solve the technical problem that the position of the hot water interface on the existing heater box is fixed and difficult to adjust, and achieve the effects of improving the versatility of the automobile heater box and reducing the development and manufacturing costs.

[0031] The pipe 4 fixing structure for the automotive heater box of the present utility model is different from the existing heater box which fixes the pipe 4 through the integrally formed mounting base 7 thereon. In the present utility model, a fixing base 2 is integrally formed on the heater box housing 1, and the mounting base 3 or a replacement of the mounting base 3 is selected and connected to the fixing base 2, and the automotive heater box pipe 4 is fixed through the fixing part 31 thereon, so that the end of the pipe 4 forms a warm water interface 8 on the heater box; during the development of the vehicle, for some vehicle models with the same heater box specifications and similar assembly requirements, a universal heater box and a one-to-one adapted mounting base 3 or a replacement of the mounting base 3 can be designed. When loading and repairing the vehicle, the appropriate mounting base 3 or a replacement of the mounting base 3 can be selected according to the vehicle model and connected to the fixing base 2, thereby changing the position of the warm water interface 8 on the heater box, so that the heater box meets the installation requirements of the corresponding vehicle model; the present utility model can effectively solve the problem that the position of the warm water interface 8 on the existing heater box is fixed and difficult to adjust. By adopting the pipe 4 fixing structure for the automotive heater box, the possibility of re-developing the heater box due to vehicle model changes can be reduced, which is beneficial to improving the universality of the automotive heater box and reducing the development and manufacturing costs.

[0032] During implementation, the mounting base 3 can be connected to the fixing base 2 by means of bonding, snap connection, etc. To improve the connection strength and facilitate maintenance, please refer to Figure 6 and Figure 7 .

[0033] In this way, the mounting base 3 is connected and fixed to the heater box housing 1 through the connecting columns 21 and the screws 6, which can not only improve the connection strength and facilitate later disassembly and maintenance, but also by setting a plurality of installation positions, in addition to selecting different mounting bases 3 or replacements of the mounting base 3 to change the position of the warm water interface 8, the position of the warm water interface 8 can also be changed by setting the same mounting base 3 or a replacement of the mounting base 3 in different installation positions, which is beneficial to further improving the flexibility of the pipe 4 fixing structure for the automotive heater box to adjust the position of the warm water interface 8, so that it meets the loading requirements of more vehicle models.

[0034] Please refer to Figure 7, the fixed base 2 further includes a rib 22 protruding from the air heater casing 1 and enclosing a rectangle, and the connecting column 21 is located inside the rib 22.

The main reinforcing rib 23 extends to be connected to the inner sidewall of the adjacent rib 22 and the connecting column 21 respectively. In this way, the side of the connecting column 21 is connected to the rib 22 and the air heater casing 1 respectively through the cross-shaped main reinforcing rib 23, which is beneficial to strengthening the connection strength of the three, and making the position where the fixed base 2 is arranged on the air heater casing 1 and the fixed base 2 itself have better structural strength.

[0037] Please refer to Figure 7 , a plurality of secondary reinforcing ribs 24 are formed by protruding inside the rib 22 on the air heater casing 1. The secondary reinforcing ribs 24 intersect with the main reinforcing rib 23, and both ends of the secondary reinforcing ribs 24 are connected to the inner sidewall of the rib 22.

In this way, not only can the connection between the upper casing 11 and the lower casing 12 be strengthened through the mounting base 3, but there are usually butted flanges at the connection of the upper casing 11 and the lower casing 12, and the structural strength is relatively good. Arranging the fixed base 2 at the connection of the upper casing 11 and the lower casing 12 is also beneficial to improving the structural stability of the fixed base 2.

[0039] For ease of understanding, the actual use of the pipe 4 fixing structure for the automotive heater box will be further described below with reference to the accompanying drawings of the specification: Please refer to Figure 7 , in this embodiment, the fixing base 2 includes three connecting columns 21 formed by protrusions on the upper housing 11 and two connecting columns 21 on the lower housing 12. The connecting column 21 located in the middle horizontally is shared and forms two mounting positions with the two connecting columns 21 on both sides respectively. That is, the fixing base 2 includes two mounting positions horizontally distributed in Figure 7 , and each mounting position includes three connecting columns 21. In addition, in this embodiment, to improve the accuracy during assembly, the distances between the connecting columns 21 in the two mounting positions are different. Figure 7 , the mounting position on the right in Figure 3 corresponds to the mounting base 3, and the mounting position on the left corresponds to the replacement of the mounting base 3. 5 Figures and 6 show the state where the mounting base 3 is connected to the fixing base 2. Figure 8 and Figure 9 show the state where the replacement of the mounting base 3 is connected to the fixing base 2. By comparing Figure 3 and Figure 8 , when using the replacement of the mounting base 3, the position of the warm water interface 8 is closer to one side edge of the heater box housing 1. By respectively selecting the mounting base 3 and the replacement of the mounting base 3, two positions of the warm water interface 8 can be provided for the heater box.
