Description

Technical Field

[0001] The utility model relates to the technical field of vehicle production and manufacturing, and in particular to a vibration isolation structure and a vehicle. Background Art

[0002] During the development of automobile noise, vibration, and harshness (NVH) performance, the vibration and noise generated by rotating parts is one of the main sources of NVH problems (such as the vibration and noise generated by the engine, electric drive, compressor, water pump, etc.). Regarding water pumps, new energy vehicles have many components that need to be cooled (such as motors, batteries, and other components with very large heat dissipation requirements), so water pumps are needed to drive the flow of coolant in the water circuit to dissipate heat for the batteries and motors to ensure their normal operation. Depending on the different heat dissipation requirements, water pumps of different powers are required, so the vibration and noise generated by the operation vary greatly. The excitation generated by some water pumps can stimulate strong resonance of the body sheet metal, causing serious NVH problems. Utility Model Content

It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0028] It should be noted that the term "plurality" used in this document refers to two or more. "And / or" describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. The character " / " generally indicates an "or" relationship between the associated objects.

[0029] During the development of automobile noise, vibration, and harshness (NVH) performance, the vibration and noise generated by rotating parts is one of the main sources of NVH problems (such as the vibration and noise generated by the engine, electric drive, compressor, water pump, etc.). Regarding water pumps, new energy vehicles have many components that need to be cooled (such as motors, batteries, and other components with very large heat dissipation requirements), so water pumps are needed to drive the flow of coolant in the water circuit to dissipate heat for the batteries and motors to ensure their normal operation. Depending on the different heat dissipation requirements, water pumps of different powers are required, so the vibration and noise generated by the operation vary greatly. The excitation generated by some water pumps can stimulate strong resonance of the body sheet metal, causing serious NVH problems.

[0030] In order to solve the above technical problems, refer to Figures 1 to 3As shown, the present application provides a vibration isolation structure, including a first vibration isolation part 10 and a second vibration isolation part 20, the first vibration isolation part 10 includes a rubber ring 11 and a rubber connecting part 12, the rubber ring 11 forms a mounting hole 111, the rubber connecting part 12 is connected to the outer peripheral side of the rubber ring 11, there are at least two rubber connecting parts 12, one of which is provided with a clamping part 121, and the other rubber connecting part 12 forms a first locking hole 122; the second vibration isolation part 20 includes a bracket 21 and a rubber mounting part 22, the rubber mounting part 22 is connected to the bracket 21, the bracket 21 is provided on the side of the rubber connecting part 12 away from the rubber ring 11, one side of the bracket 21 is clamped into the clamping part 121, and the other side of the bracket 21 forms a second locking hole 211 corresponding to the first locking hole 122, the first locking hole 122 and the second locking hole 211 are inserted into and connected by a locking part (not shown). Thus, the mounting hole 111 of the rubber ring 11 is used to mount the rotating workpiece 1, and the rubber connecting portion 12 can be connected to the bracket 21 of the second vibration isolation portion 20. Specifically, one side of the bracket 21 is engaged with the snap-fitting member 121, and the other side of the bracket 21 forms a second locking hole 211 corresponding to the first locking hole 122. The first locking hole 122 and the second locking hole 211 are inserted through the locking member to connect the bracket 21 and the rubber connecting portion 12. Because the rubber ring 11, the rubber connecting portion 12, and the rubber mounting portion 22 are all made of rubber, which has a good vibration isolation effect, the vibration intensity caused by the rotation of the rotating workpiece 1 is weakened by the rubber ring 11, the rubber connecting portion 12, and the rubber mounting portion 22, thereby weakening the vibration transmitted to the vehicle, thereby reducing the resonance of the body sheet metal and improving the NVH performance.

[0031] In some embodiments, the rubber ring 11, rubber connecting portion 12, and rubber mounting portion 22 are all made of rubber. Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce significant deformation under a very small external force, but can return to its original shape after the external force is removed. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is processed by extracting gum from plants such as rubber trees and rubber grass; synthetic rubber is obtained by polymerization of various monomers.

[0032] In some embodiments, the rubber connecting portion 12 is arranged on the outer peripheral side of the rubber ring 11 close to the bracket 21, reducing the thickness of the rubber connecting portion 12 and enabling the rubber connecting portion 12 to be connected to the bracket 21, thereby improving the vibration isolation effect while ensuring the connection stability.

[0033] In some embodiments, reference Figures 1 to 3 As shown, the number of rubber connecting parts 12 can be set to multiple according to actual conditions. In this embodiment, there are mainly two rubber connecting parts 12, corresponding to the two sides of the connecting bracket 21, so as to at least form a stable connection structure.

[0034] In some embodiments, the bracket 21 can be set as a plastic bracket and a rubber bracket. The stiffness of the plastic bracket is generally greater than the stiffness of the rubber material, which can reduce the deformation degree of the bracket 21, reduce the risk of the bracket falling off from the clamping member 121, and maintain the connection stability between the bracket 21 and the rubber connecting part 12.

[0035] In some embodiments, reference Figure 3 As shown, the first locking hole 122 and the second locking hole 211 can be threaded through holes, and the locking member (not shown) is a threaded locking member. After passing through the first locking hole 122 and the second locking hole 211, the locking member is screwed into the threaded portion of the threaded locking member through a nut, thereby locking the connecting bracket 21 and the rubber connecting part 12.

[0036] In some embodiments, reference Figure 3 As shown, the clamping member 121 and the rubber connecting portion 12 are configured as an integral structure; the bracket 21 and the rubber mounting portion 22 are configured as an integral structure. The clamping member 121 and the rubber connecting portion 12 are formed into an integral structure through a vulcanization process, and the bracket 21 and the rubber mounting portion 22 are formed into an integral structure through a process such as injection molding. Optionally, the rubber ring 11 and the rubber connecting portion 12 can also be configured as an integral structure.

[0037] In some embodiments, reference Figure 3 As shown, the rubber ring 11 is an annular rubber ring, and the mounting hole 111 is an annular mounting hole. The mounting hole 111 is used to mount a rotating workpiece such as a water pump. The shapes of the annular rubber ring 11 and the annular mounting hole 111 match the shapes of the rotating workpiece 1, so that the rotating workpiece 1 can be tightly mounted within the annular rubber ring 11.

[0038] In some embodiments, reference Figure 3 As shown, a fracture 112 is formed in the rubber ring 11, forming a first cross-section 1121 and a second cross-section 1122 at the fracture 112. The first vibration isolation portion 10 includes a snap assembly 13, which includes a protrusion 131 formed on the first cross-section 1121 and a slot 132 formed on the second cross-section 1122. The protrusion 131 snaps into the slot 132. The snap assembly 13 can open and close the fracture 112. When the protrusion 131 snaps into the slot 132, the fracture 112 is closed. When the protrusion 131 is released from the slot 132, the fracture 112 is opened. After the fracture 112 is opened, the water pump is placed into the mounting hole 111, and the first cross-section 1121 and the second cross-section 1122 are brought into contact with each other by the snap assembly 13.

[0039] In some embodiments, reference Figure 3As shown, the width of the protrusion 131 on the side away from the first section 1121 is greater than the width on the side close to the first section 1121; the width of the locking groove 132 on the side away from the second section 1122 is greater than the width on the side close to the second section 1122. Thus, the protrusion 131 further forms a protrusion structure on the side away from the first section 1121, so that it can be locked into the locking groove 132 to form a locking structure.

[0040] In some embodiments, reference Figure 3 As shown, the cutout 112 extends from the rubber ring 11 to the rubber connecting portion 12. Locking members are used to secure the two sides of the cutout 112 on the corresponding rubber connecting portion 12. Based on the snap-fit structure formed by the snap-fit assembly 13, locking the cutout 112 with the locking members further stabilizes the rotating workpiece. During installation, the rotating workpiece is mounted in the mounting hole 111, initially secured by the snap-fit assembly 13, and then secured with the locking members. This facilitates installation and provides good installation stability.

[0041] In some embodiments, reference Figure 3 and Figure 4 As shown, the rubber mounting portion 22 connects to the bracket 21 and protrudes toward the side facing away from the first vibration isolation portion 10. The rubber mounting portion 22 comprises an integral outer portion 221 and an inner core portion 222. The inner core portion 222 is located axially inward of the outer portion 221 and is made of metal. The inner core portion 222 is provided with a hole 2221. The rubber mounting portion 22 is used to connect the second vibration isolation portion 20 to the vehicle body sheet metal. The rubber mounting portion 22 protrudes toward the side facing away from the first vibration isolation portion 10, that is, toward the vehicle body sheet metal. This protruding rubber mounting portion 22 isolates the bracket 21 from the vehicle body sheet metal, thereby reducing vibration transmitted to the vehicle body by the rotating mounting portion. The outer portion 221 and the inner core portion 222 are formed into an integral structure through a vulcanization process. A threaded fastener provided in the hole 2221 of the inner core portion 222 secures the second vibration isolation portion 20 to the vehicle body sheet metal.

[0042] In some embodiments, reference Figures 3 to 5 As shown, a notch 213 corresponding to the clamping member 121 can be formed on the side of the bracket 21 facing the clamping member 121. When the bracket 21 is engaged with the clamping member 121, the clamping member 121 and the notch 213 engage with each other. The clamping member 121 includes a claw 1211 and a clamping portion 1212. The claws 1211 extend from the same side to form a groove structure between the two claws 1211, which serves as the clamping portion 1212. The clamping portion 1212 can accommodate the bracket 21 and clamp the bracket 21 by engaging the claws 1211 with the notch 213.

[0043] In some embodiments, reference Figures 3 to 5As shown, one rubber mounting portion 22 is provided on one side of the bracket 21, and two rubber mounting portions 22 are provided on the other side of the bracket 21. These two rubber mounting portions 22 form a triangular mounting structure, which provides both stable installation and cost savings. Specifically, a raised mating structure is formed on the side of the rubber mounting portion 22 facing the body sheet metal, allowing the raised mating structure to extend into the body sheet metal, providing greater structural stability.

[0044] In some embodiments, reference Figure 5 As shown, a grid structure 212 is formed at the bottom of the bracket 21. This can reduce the weight of the bracket 21 and the manufacturing cost while ensuring the structural strength of the bracket 21.

[0045] The present application also provides a vehicle, including a water pump and a vibration isolation structure, wherein the water pump is disposed in a mounting hole 111 of the first vibration isolation structure.

[0046] In this application, unless otherwise specified or limited, the terms "disposed (provided with)" and "connected" should be understood in a broad sense.
