Description

Technical Field

[0001] The utility model relates to the technical field of installation structures of vehicle radiators or cooling modules, and specifically relates to a vehicle radiator mount. Background Technique

[0002] Generally, the cooling module of a passenger car or a commercial vehicle includes core components such as a condenser and a radiator. As an important part of the engine cooling system, its function is to forcibly cool the engine to ensure that the engine water temperature is maintained at a reasonable state and prevent the engine water temperature from being too high and malfunctioning. The condenser and radiator need to be connected to the vehicle frame through relevant installation structures to ensure their structural stability. In the prior art, most cooling modules adopt mount supports to connect with the vehicle frame. Among them, one end of the radiator mount is connected to the vehicle frame, and the left end is connected to the radiator, which is used for the fixed connection between the radiator and the vehicle frame. And the radiator mount generally adopts a rubber cushion. While supporting and connecting the radiator, the rubber cushion can provide bearing buffering between the radiator and the vehicle frame, improving the overall NVH performance of the vehicle.

[0003] Through retrieval, relevant technical documents such as vehicle cooling modules or radiator mounts and mounting brackets have been publicly disclosed in the prior art. For example, the utility model patent with the publication number "CN216545713U" and the name "Split Radiator Mount Assembly and Vehicle". It discloses a split radiator mount assembly and a vehicle. The split radiator mount assembly includes a mount bracket connected to the radiator and provided with mounting holes; a bushing structure including a bushing body and an elastic part connected to the bushing body. The elastic part surrounds the bushing body along the circumferential direction of the bushing body. The bushing structure is inserted through the mounting hole, and the elastic part is located within the mounting hole, and at least one end protrudes out of the mounting hole along the corresponding side of its axial direction; a first elastic pad located on one side of the mount bracket and inserted through the bushing body to be in contact with the elastic part; a second elastic pad located on the other side of the mount bracket and inserted through the bushing body to be in contact with the elastic part; a connection component that connects the mount bracket to the vehicle frame through the bushing structure, the first elastic pad and the second elastic pad. The radiator mount assembly in this comparative document is a split structure. Specifically, the first elastic pad and the second elastic pad are installed on both sides of the mount bracket to provide flexible bearing between the radiator and the vehicle frame. However, the center of its elastic pad is rigidly connected to the vehicle frame through bolts, which actually results in a rigid connection point between the vehicle frame and the connection component, which will cause vibration transmission between the radiator and the vehicle frame and is not conducive to the overall NVH performance of the vehicle.

[0004] For example, the utility model patent with the publication number of "CN204296448U" and the name of "A radiator buffer pad and an automobile" discloses a radiator buffer pad, which includes: a rubber pad, and the rubber pad includes a first connection structure, a second connection structure, and a groove structure located between the first connection structure and the second connection structure for clamping with a radiator bracket. The groove structure is integrally formed with the first connection structure and the second connection structure, and through holes are provided in the middle of the three; a sleeve connected to the rubber pad, and the sleeve includes a sleeve structure matching the through hole and a sleeve cover plate structure with a round hole having the same aperture as the sleeve structure. The sleeve, the rubber pad, and the radiator bracket connected to the rubber pad are fixed to the vehicle body through mounting bolts. The radiator buffer pad involved in this comparative document realizes the flexible connection between the radiator and the vehicle frame, but it does not consider the installation convenience between the radiator buffer pad, the radiator, and the vehicle frame.

[0005] Therefore, it is of great significance to propose a vehicle radiator mount in the field that is convenient for disassembly and assembly and can provide bearing buffering between the radiator and the vehicle frame. Utility Model Content

The connection seat includes a split connection seat one and connection seat two, and the elastomer at least includes a rubber body; the inner sides of the connection seat one and connection seat two have semi-cylindrical sides, and a cylindrical cavity is formed after the connection seat one and connection seat two are combined and connected; the upper and lower ends of the rubber body are both bosses with an outer diameter larger than the inner diameter of the cylindrical cavity, and the middle part is a cylindrical section matching the size of the cylindrical cavity; after the cylindrical section is embedded in the cylindrical cavity, the bosses overlap on the outer end surface of the cylindrical cavity; a through cylindrical hollow hole is provided in the center of the rubber body.

[0007] Furthermore, it further includes a cover plate, and a through hole one is provided in the center of the cover plate. The cover plate covers the boss.

[0012] Further, a positioning protrusion is provided on the inner end surface of the boss, and positioning surfaces are provided on both sides of the positioning protrusion. When the connecting seat I and the connecting seat II are combined, the end surface of the rear semi-cylindrical side surface of the cylindrical cavity contacts the positioning surface.

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0026] As Figure 1 shown, a vehicle radiator mount includes a connecting seat connected to the radiator and an elastomer connected to the vehicle frame. The connecting seat includes a split connecting seat one 21 and a connecting seat two 22. The elastomer includes at least a rubber body 24. The inner sides of the connecting seat one 21 and the connecting seat two 22 have semi-cylindrical sides 211. After the connecting seat one 21 and the connecting seat two 22 are combined and connected, a cylindrical cavity 222 is formed. The upper and lower ends of the rubber body 24 are both bosses 241 with an outer diameter larger than the inner diameter of the cylindrical cavity 222, and the middle part is a cylindrical section 242 with a size matching that of the cylindrical cavity 222. After the cylindrical section 242 is inserted into the cylindrical cavity 222, the boss 241 overlaps the outer end face of the cylindrical cavity 222. The rubber body 24 has a through cylindrical hollow hole 243 in the center.

[0027] In this embodiment, the first connecting seat 21 is connected to the radiator, and the lower boss 241 of the rubber body 24 is in contact connection with the vehicle frame. The rubber body 24 is designed to be similar to a dumbbell or spindle shape. Its upper and lower end faces are both bosses 241. After the upper and lower bosses 241 are lapped on the outer end face of the cylindrical cavity 222, the bottom boss 241 is spaced apart from the vehicle frame, providing flexible bearing between the vehicle frame and the radiator. When the first connecting seat 21 and the second connecting seat 22 are combined and connected, the cylindrical cavity 222 is engaged with the outer peripheral side of the cylindrical section 242 of the rubber body 24. The cooperation of the upper and lower bosses 241 can provide vertical and radial limits and supports for the rubber body 24, improving the connection stability between the vehicle frame and the radiator. The first connecting seat 21 and the second connecting seat 22 are designed as split semi-circular structures, which are convenient for disassembly and assembly. When the rubber body 24 needs to be replaced, the first connecting seat 21 and the second connecting seat 22 can be directly separated to disassemble and replace the rubber body 24. The cylindrical hollow hole 243 in the center of the rubber body 24 can be used as the installation and fixing hole of the rubber body 24. The lower boss 241 and the vehicle frame can be fixedly connected by passing a bolt through it. The shape of the boss 241 is preferably a circular boss in this embodiment, and it can also be square or other shapes. However, it is undoubtedly confirmed that the outer diameter or outer dimension of the boss 241 is larger than the inner diameter of the cylindrical cavity 222, so that the boss 241 can be lapped on the outer end face of the cylindrical cavity 222. The outer end face of the cylindrical cavity 222 is preferably a plane, so that it can be completely in contact with the boss 241.

[0028] Although the above-mentioned implementation provides a basic design solution, the boss 241 at the top of the rubber body 24 is in contact and fixed with the bolt, and its stress area is too small, which is not conducive to the force bearing of the top end face of the boss 241. Therefore Figure 2 A more preferred implementation is shown. That is, the elastomer further includes a cover plate 23. A through hole one 231 is opened in the center of the cover plate 23. The cover plate 23 covers the boss 241. The bolt passes through the through hole one 231 of the cover plate 23 and extends out from the bottom of the cylindrical hollow hole 243 in the center of the rubber body 24, and finally extends out of the bottom boss 241 of the rubber body 24 and is fixedly connected to the vehicle frame. Such a design can increase the stress area of the boss 241 at the top of the rubber body 24 and prevent the local stress of the boss 241 from being too large and failing.

[0029] On the basis of the above-mentioned implementation, it can be further optimized. The cover plate 23 can be designed as a pair, which respectively cover the bosses 241 at the upper and lower ends of the rubber body 24. The cover plate 23 at the bottom cooperates with the bottom boss 241 and the vehicle frame to be fixedly connected, which can also make the bearing of the bottom boss 241 more uniform.

[0030] Another more preferred implementation can be Figure 3As shown. The elastomer further includes a hollow support column 26 vertically connected to the center of the cover plate 23. The outer diameter of the hollow support column 26 matches the inner diameter of the cylindrical hollow hole 243. The cover plate 23 and the hollow support column 26 form a support member 27. The support member 27 forms a T-shaped rigid member. The hollow support column 26 is inserted into the cylindrical hollow hole 243 of the rubber body, providing rigid support for the axial and radial directions of the rubber body 24, and improving the stability of the connection.

[0031] Another more preferred embodiment may be Figure 4 As shown. It is characterized in that: there are a pair of the support members 27. After the respective hollow support columns 26 are symmetrically inserted into the cylindrical hollow holes 243, the cover plates 23 are respectively covered on the bosses 241 at the upper and lower ends of the rubber body 24. The paired support members 27 can provide rigid support and limit for the axial, radial and vertical directions of the rubber body 24. Preferably, the hollow support columns 26 of the support members 27 abut against each other. In this way, even if the rubber body 24 is damaged as a whole, the paired support members 27 can still provide stable rigid support and limit, preventing the radiator from coming off.

[0032] In a further preferred embodiment, the first connecting seat 21 is integrally connected to the fixing plate 212. A plurality of second through holes 214 are opened on the fixing plate 212. A pair of bolt seats 213 are provided in the middle of the semi-cylindrical side surface 211 of the first connecting seat 21; a pair of bolt seats 221 are provided in the middle of the semi-cylindrical side surface 211 of the second connecting seat 22; the first connecting seat 21 and the second connecting seat 22 are fixedly combined and connected through bolts cooperating with the bolt seats 213 and bolt seats 221 to form a cylindrical cavity 222. The fixing plate 212 uses the second through holes 214 to cooperate with bolts to connect the entire suspension and the radiator. After the rubber body 24 is clamped into the semi-cylindrical side surface 211 of the first connecting seat 21, the second connecting seat 22 is combined and connected. At this time, the bolt seats 213 and bolt seats 221 are aligned, and the bolt seats 213 and bolt seats 221 are locked with bolts to complete the assembly of the entire radiator suspension. Then, the radiator suspension is fixedly connected to the vehicle frame by passing bolts through the support member 27 or the cover plate 23 or the rubber body 24, and the connection and installation of the radiator suspension are completed. The entire assembly process is fast and convenient.

[0033] In a further preferred embodiment, in order to ensure that after the rubber body 24 is clamped into the semi-cylindrical side surface 211 of the first connecting seat 21 and the first connecting seat 21 and the second connecting seat 22 are assembled and connected, the inner side surface of the cylindrical cavity 222 contacts the outer peripheral side of the cylindrical section 242 of the rubber body 24. As Figure 5 and Figure 6 shown, the inner end surface of the boss 241 has a positioning protrusion 244. The two sides of the positioning protrusion 244 are positioning surfaces 2441. When the first connecting seat 21 and the second connecting seat 22 are combined, the end surface of the semi-cylindrical side surface 211 of the cylindrical cavity 222 contacts the positioning surface 2441.

[0034] In a further preferred embodiment, a pair of positioning protrusions 244 are distributed radially along the boss 241.

[0035] In a further preferred embodiment, the first through hole 231 on the cover plate 23 is an oblong hole. The oblong hole can facilitate the adjustment and alignment when the bolt fixes the suspension and the vehicle frame.

[0036] In a further preferred embodiment, the outer sides of the first connecting seat 21 and the second connecting seat 22 are hollowed out to achieve the light weight of the first connecting seat 21 and the second connecting seat 22 as much as possible.
