Description

Automobile radiator installation structure

Technical Field

The utility model belongs to the technical field of automobile parts assembly, and in particular relates to an automobile radiator installation structure.

Background Art

The automobile radiator is the main component used for heat dissipation of parts in the front cabin of the automobile, and is usually installed horizontally on the front frame at the front of the front cabin. Due to the relatively large size and weight of the radiator, in order to ensure the stable and reliable installation of the radiator, it is usually necessary to set multiple connection points with the front frame. In the existing radiator installation structure, basically at least two radiator mounting brackets are respectively set on the upper beam and the lower beam of the front frame, and then the upper and lower parts of the radiator body are respectively fixedly connected with the corresponding radiator mounting brackets by bolts. This installation structure has relatively high requirements for the position accuracy of each radiator mounting bracket on the upper beam and the lower beam. If the position of one of the radiator mounting brackets is offset, it is necessary to adjust the bracket position multiple times, making the radiator assembly difficult or even impossible, with high manufacturing costs and low assembly efficiency. In particular, for the front frame whose upper beam and lower beam are not an integrated structure, it is easy to be affected by the cumulative assembly error of the upper beam and the lower beam, so that the position of the radiator mounting bracket on the upper beam and the radiator mounting bracket on the lower beam is misaligned. In addition, the existing radiator mounting brackets are mostly integral stamped sheet metal parts with poor seismic isolation effect. The vibration of the radiator when working is easily transmitted along the bracket through the car body to the cockpit, generating loud noise and affecting the user's driving experience.

Therefore, there is an urgent need to provide a new automobile radiator mounting structure, which is expected to reduce the requirements for the position accuracy of the radiator mounting bracket and improve the assembly efficiency, thereby reducing the manufacturing cost while ensuring the stable and reliable installation of the radiator. At the same time, it can reduce the NVH of the whole vehicle and improve the driving experience.

The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the illustrations provided in the following embodiments are only used to illustrate the basic concept of the present invention, and the following embodiments and the features in the embodiments can be combined with each other without conflict.

Please refer to Figures 1-3. This embodiment discloses a car radiator installation structure, including an upper installation beam 2 and a lower installation beam 3 respectively arranged on the upper and lower sides of the radiator body 1, and two lower installation brackets 4 fixed on the lower installation beam 3 and corresponding to the lateral sides of the radiator body 1. Here, "upper and lower" refer to the upper and lower sides based on the vertical direction of the vehicle body, and "lateral" refers to the lateral direction of the vehicle body (that is, the width direction of the vehicle body). Here, the installation connection between the upper installation beam 2 and the lower installation beam 3 and the vehicle body structure is an existing structure. Specifically, the upper installation beam 2 is the front end of the car. The upper crossbeam of the module frame is usually an assembly beam welded from stamped sheet metal parts, and its two ends are connected to the corresponding ends of the front energy absorption box of the car through corresponding overlapped brackets. The lower mounting crossbeam 3 is a steel pipe beam arranged relatively parallel to the upper mounting crossbeam 2, which plays a vertical supporting role for the radiator body 1 to ensure the stable and reliable installation of the radiator body 1, which will not be repeated here; by installing the radiator body 1 between the upper mounting crossbeam 2 and the lower mounting crossbeam 3, the installation stability of the radiator body is ensured; preferably, the lower mounting bracket 4 is fixedly connected to the lower mounting crossbeam 3 by bolts;

The upper part of the radiator body 1 is connected to the upper mounting crossbeam 2, and the lower mounting bracket 4 is provided with a radiator mounting hole 4a that penetrates horizontally along the vehicle body, and the lateral sides of the radiator body 1 are respectively formed with plug-in parts 1a that are plugged and supported in the radiator mounting hole 4a of the corresponding side lower mounting bracket 4. It can be known that here is usually a properly arranged axial hole matching plug-in structure, and the "and supporting" here refers to the lower mounting bracket 4 playing a vertical supporting role for the radiator body 1; there are many ways to connect the upper part of the radiator body 1 with the upper mounting crossbeam 2, usually corresponding connecting holes are designed on the upper mounting crossbeam 2, and the fixed connection is completed by passing bolts through the connecting holes; or an upper mounting bracket is designed, a vertical pin hole is designed on the upper mounting bracket, and a pin is designed on the upper mounting crossbeam 2, and the connection is completed by plugging the pin into the pin hole; these are the existing connection structures between the upper mounting crossbeam 2 and the radiator body 1, and a certain method can be selected according to needs to complete the connection between the radiator body 1 and the upper mounting crossbeam 2, which is not limited here;

In the above structural design, the installation stability of the radiator body is high, and at the same time, the position accuracy requirements for each radiator mounting bracket are reduced, which is beneficial to improving the overall assembly efficiency of the radiator body and reducing the manufacturing cost. Specifically, the upper part of the radiator body 1 is connected to the upper mounting crossbeam 2 to limit the position of the radiator body 1, and the lower part is supported by the lower mounting bracket 4 to complete the stable support of the radiator body 1. The overall structure is simple and the installation is stable and reliable. Moreover, since the radiator body 1 is inserted into the radiator mounting hole 4a that passes through the lower mounting bracket 4 horizontally, when the radiator body 1 is installed, the radiator body 1 can be adjusted to a certain horizontal position along the radiator mounting hole 4a that passes through the lower mounting bracket 4. Even if the upper mounting crossbeam 2 and the lower mounting crossbeam 3 are adjusted, There is a certain misalignment in the installation point position of the radiator body 1, and there is no need to adjust the position of the corresponding mounting brackets on the upper mounting beam 2 and the lower mounting beam 3. The radiator body 1 can be installed in place by lateral adjustment of the radiator body 1, which reduces the requirements for the position accuracy of each mounting bracket to a certain extent, which is beneficial to improving the overall assembly efficiency of the radiator body and reducing manufacturing costs. It should be noted that when the upper mounting beam 2 and the lower mounting beam 3 are connected and installed with the vehicle body structure, it is easy to produce cumulative assembly errors in the lateral direction of the vehicle body, which leads to misalignment of the upper and lower mounting points of the radiator in the lateral direction of the vehicle body. Therefore, in the present technical solution, the radiator body 1 can compensate for the lateral error of the vehicle body, which can be applied to most vehicle models and has good practicality.

In this embodiment, the lower mounting bracket 4 includes a base 401 fixed on the lower mounting beam 3 and a seismic isolation rubber pad 402 fixed and sleeved in the base 401. The radiator mounting hole 4a is formed on the seismic isolation rubber pad 402. Specifically, a lower mounting bracket support plate 301 is welded and fixed on the lower mounting beam 3. The base 401 is detachably fixed to the lower mounting bracket support plate 301 by bolts. The seismic isolation rubber pad 402 is preferably a rubber pad, which can be fixed in the base 401 by interference fit, vulcanization fixation, etc. In this structural design, the seismic isolation rubber pad 402 can be designed to play a seismic isolation role, which is beneficial to improving the NVH performance of the whole vehicle. At the same time, the frame of the radiator body is protected under extreme working conditions to prevent severe impact from damaging the frame of the radiator body. At the same time, the seismic isolation rubber pad 402 can use its own flexibility to further compensate for the position errors of the upper and lower mounting beams and the radiator mounting bracket, which is beneficial to the assembly of the radiator body.

In this embodiment, the radiator mounting hole 4a is an asymmetric hole, which refers to a non-axisymmetric hole and a non-center symmetric hole. Of course, the plug-in portion 1a of the radiator body 1 is conformally configured to the radiator mounting hole 4a. In conventional plug-in structures, the plug-in holes are basically symmetrical holes. During assembly, employees are required to identify the assembly posture of the parts before assembly, which has low assembly efficiency and the possibility that the lower mounting bracket 4 is installed upside down. This structure can achieve structural anti-misinstallation by designing the radiator mounting hole 4a as an asymmetric hole. During installation, the lower mounting bracket 4 can only be installed on the radiator body 1 at a specific angle and a specific side of the plug-in sleeve, thereby improving the consistency of product assembly, improving product quality, and further improving assembly efficiency.

In this embodiment, a lower mounting bracket support plate 301 is formed on the lower mounting cross beam 3 extending rearward along the front-to-rear direction of the vehicle body, and the base 401 is fixed on the lower mounting bracket support plate 301. Of course, the lower mounting bracket support plate 301 corresponds to the lower mounting bracket 4 in two pieces. Specifically, the lower mounting bracket support plate 301 is welded and fixed to the lower mounting cross beam 3, and the base 401 is fixed to the lower mounting bracket support plate 301 by bolts. The overall structure is simple, and the design of the lower mounting bracket support plate 301 is conducive to forming an effective support for the base 401.

In this embodiment, the lower mounting cross beam 3 is a calf protection beam, which is also the auxiliary anti-collision beam of the automobile. The calf protection beam is used as the lower supporting beam of the radiator body 1, which improves the spatial compactness of the overall structure, improves the versatility of components, and is beneficial to the spatial layout in the front cabin of the vehicle.

In this embodiment, the base 401 has a T-shaped structure and is invertedly installed on the lower mounting bracket support plate 301. Specifically, two bolt holes are provided on the wing plate of the T-shaped structure, and steel bushings are also designed in the bolt holes. The fixed installation with the lower mounting bracket support plate 301 is completed by bolts. The T-shaped base 401 in this structural design has a simple structure, good load-bearing capacity, and good torsional stiffness, which is beneficial to further ensure the stable support of the radiator body 1.

In this embodiment, the web 401a of the base 401 is provided with reinforcing ribs 401b on both sides along the front-rear direction of the vehicle body, and the reinforcing ribs 401b are arranged close to one side of the radiator body 1. Specifically, the reinforcing ribs 401b here are triangular plate reinforcing ribs. By designing the reinforcing ribs 401b close to the side of the radiator body 1, it is beneficial to enhance the structural strength of the side of the base 401 close to the radiator body 1, and further improve the durability of the lower mounting bracket. The side away from the radiator body 1 does not need to be designed with reinforcing ribs 401b, which is beneficial to the assembly of connecting bolts.

In this embodiment, the seismic isolation rubber pad 402 is evenly distributed with multiple weight-reducing holes 402a along the circumference of the radiator mounting hole 4a. The design of the weight-reducing holes 402a is beneficial to the lightweight design of the bracket and, at the same time, is beneficial to improving the vibration reduction performance of the seismic isolation rubber pad 402.

In this embodiment, the two lower mounting brackets 4 are symmetrically arranged relative to the vertical center axis of the radiator body 1. The symmetrical arrangement has a simple structure and is convenient for arrangement.

In this embodiment, radiator support arms 101 are integrally formed on both lateral sides of the radiator body 1. Specifically, the radiator support arm 101 and the outer frame of the radiator body 1 are an integrally formed structure. The integrally formed structure has reliable connection and good strength, and is conducive to controlling the position and dimensional accuracy. The radiator support arm 101 extends outward from one end away from the radiator body 1 to form a protruding column, and the protruding column is conformally arranged with the radiator mounting hole 4a. The protruding column is the plug-in portion 1a. In this structural design, the radiator support arm 101 is designed to ensure a stable connection between the radiator body 1 and the lower mounting bracket, and to simplify assembly.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
