Description

Technical Field

[0001] This application relates to the field of vehicle technology, and more particularly to a vibration-absorbing device for a vehicle and a vehicle. Background Technology

[0002] In modern automotive manufacturing, the vehicle floor area typically includes complex structural components such as the power battery, high-voltage wiring harness, seat rails, auxiliary instruments, air ducts, and low-voltage wiring harness. During vehicle operation, resonance can easily occur, causing the structural components to vibrate and transmit noise into the vehicle interior, resulting in excessive interior noise or unusual rattles.

[0003] With the development of the modern vehicle industry, consumers' demands for vehicle comfort are constantly increasing, and vehicle noise issues are affecting consumers' driving experience. Utility Model Content

[0004] Therefore, this application provides a vibration-absorbing device and a vehicle, which solves the technical problem of excessive noise or abnormal sounds inside the vehicle, thereby improving the driving experience for consumers.

[0005] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a vibration-absorbing device for vehicles.

[0007] This application provides a vibration-absorbing device for vehicles, comprising:

[0008] A mass component having an assembly portion that extends through both opposite sides of the mass component in the thickness direction;

[0009] A vibration damping assembly includes a damping element, a first support element, and a second support element. At least a portion of the damping element is disposed within the assembly portion. The damping element has an installation channel, which has a first end and a second end in an extending direction. At least a portion of the first support element is disposed within the first end, and the first support element has a first mounting portion. At least one second support element is disposed within the second end, and the second support element has a second mounting portion. Both the first mounting portion and the second mounting portion are used to detachably mount the vibration damping assembly to the floor of a vehicle.

[0010] This application provides a vibration-absorbing device for vehicles. A mass member has an assembly portion, allowing at least a portion of a damping element to be housed within the mass member. The mass member contacts the damping element, enabling the damping element to absorb energy generated by vehicle vibrations. The damping element has a mounting channel with a first end and a second end in its extending direction. At least a portion of a first support member is located within the first end, and at least a portion of a second support member is located within the second end, allowing the first and second supports to be connected to the damping element. The first support member has a first mounting portion, and the second support member has a second mounting portion. Both the first and second mounting portions are used to connect to the vehicle floor, enabling a detachable connection between the damping element and the vehicle floor. This facilitates disassembly and improves the installation flexibility of the vibration-absorbing device.

[0011] When the vehicle floor vibrates, the energy generated by the vibration is transmitted to the damping component through the first mounting part and the second mounting part. The damping component can efficiently absorb the energy generated during vehicle operation, thereby reducing the noise transmitted into the vehicle body during vehicle operation and improving the driving experience.

[0012] Furthermore, through contact with the vibration damping component, some vibration is transmitted to the mass component. The mass component can generate a counterforce against the vibration, thereby significantly reducing the vibration amplitude and further reducing noise transmitted into the vehicle body during driving, improving the driving experience. When the weight and size of the mass component are different, the magnitude of the counterforce generated by the mass component against the vibration is different, and the reduction in vibration amplitude is different. The vibration absorption device for vehicles provided in this application embodiment has a simple structure and can meet the vibration amplitude requirements of different frequencies by changing the weight and size of the mass component, thereby improving the frequency coverage and versatility of the vibration absorption device provided in this application embodiment.

[0013] Therefore, an embodiment of this application provides a vibration-absorbing device for vehicles, comprising a mass component and a damping assembly. The damping component is housed within the mass component, and a first support component and a second support component detachably connect the damping component to the vehicle floor. The damping component efficiently absorbs energy generated during vehicle operation, while the mass component reduces vehicle vibration amplitude, thereby reducing noise transmitted into the vehicle body and improving the driving experience. Furthermore, by varying the weight and size of the mass component, the frequency coverage and versatility of the vibration-absorbing device provided in this application embodiment are improved to meet the vibration amplitude requirements of different frequencies. The detachable connection of the damping assembly to the vehicle floor enhances the installation flexibility of the vibration-absorbing device.

[0014] In one possible implementation of this application, the first support member and the second support member are connected at their two ends close to each other.

[0015] In one possible implementation of this application, the first support member and the second support member are inserted into each other at their close ends.

[0016] In one possible implementation of this application, the installation channel has an inner wall, and the circumferential outer wall of at least one of the first support member and the second support member is connected to the inner wall of the channel.

[0017] In one possible implementation of this application, the assembly part is an assembly hole, and the circumferential outer wall of the damper has a protrusion protruding toward the mass member, the protrusion contacting the hole wall of the assembly hole.

[0018] In one possible implementation of this application, the number of protrusions is at least two, and the protrusions are spaced apart on the circumferential outer wall of the damping member along the depth direction of the mounting hole.

[0019] In one possible implementation of this application, the circumferential outer wall of the damper further has a first limiting portion and a second limiting portion protruding toward the mass member;

[0020] The first limiting part is located in the area where the first support member is provided on the vibration damper, and at least a portion of the first limiting part is located outside the assembly part and abuts against the mass member;

[0021] The second limiting portion is located in the area where the second support member is provided on the vibration damper, and at least a portion of the second limiting portion is located outside the assembly portion and abuts against the mass member.

[0022] In one possible implementation of this application, both the first limiting part and the second limiting part are annular structures.

[0023] In one possible implementation of this application, both the first mounting part and the second mounting part have mounting holes for a connector to be inserted into the floor.

[0024] The second mounting part is coaxially arranged with the first mounting part and is interconnected with it.

[0025] Secondly, embodiments of this application provide a vehicle, including:

[0026] floor;

[0027] The vibration-absorbing device as described in any of the first aspects above, wherein the vibration-absorbing device is disposed on the floor;

[0028] A connector is inserted into the first and second mounting portions of the vibration-absorbing device and is detachably connected to the floor.

[0029] This application provides a vehicle in which a vibration-absorbing device is detachably connected to the floor by inserting a connector through a first mounting portion and a second mounting portion. Since this vehicle includes the vibration-absorbing device provided in any of the embodiments of the first aspect, the vibration-absorbing device used in this vehicle also has the same technical effect as the vibration-absorbing device provided in the first aspect, namely, it can reduce noise transmitted to the vehicle body during vehicle operation and improve the driving experience. Furthermore, by changing the weight and size of the mass component to meet the vibration amplitude requirements of different frequencies, the frequency coverage and versatility of the vibration-absorbing device provided in this application are improved. The detachable connection between the vibration damping component and the vehicle floor increases the installation flexibility of the vibration-absorbing device. Attached Figure Description

These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0044] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0045] Furthermore, in the embodiments of this application, directional terms such as "upper," "lower," "left," and "right" are defined relative to the positions in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms are relative concepts, used for relative description and clarification, and can change accordingly depending on the position of the components in the accompanying drawings.

[0046] In the embodiments of this application, unless otherwise explicitly specified and limited, the term "connection" should be interpreted broadly. For example, "connection" can mean a fixed connection, a detachable connection, or an integral part; it can mean a direct connection or an indirect connection through an intermediate medium.

[0047] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0048] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0049] This application provides a vehicle embodiment. It should be noted that this application embodiment does not limit the vehicle type. For example, the vehicle in this application embodiment can be a sedan, an off-road vehicle, a multi-purpose vehicle (MPV), or other types of vehicles.

[0050] In this application embodiment, the type of power source of the vehicle is not limited. For example, for a fuel vehicle, the power source may refer to a fuel engine such as a gasoline engine or a diesel engine; for an electric vehicle, the power source may refer to an electric motor; for a hybrid vehicle, the power source may refer to an engine or an electric motor; for a vehicle powered by other means, the power source may refer to a device that generates power.

[0051] This application provides a vehicle including a floor 400. The vehicle floor 400 is an important component of the vehicle body and is typically located at the bottom of the vehicle body. The vehicle floor 400 is usually stamped from high-strength steel sheet and connected to the side panels, front bulkhead, rear longitudinal beams, and other structures of the vehicle body to form an integral rigid structure through welding.

[0052] In this application, no further restrictions are placed on the material of the floor 400 or the connection method between the floor 400 and the side panels, front panels, rear longitudinal beams, etc. of the vehicle body. It is only necessary to meet the rigidity and integrity requirements of the vehicle.

[0053] See Figure 5 and Figure 6 In this vehicle, the floor 400 typically houses numerous vehicle structural components. Taking an electric vehicle as an example: in the height direction of the vehicle, the side of the floor 400 closest to the road surface typically houses the power battery 410 and high-voltage wiring harness 460. The side of the floor 400 facing away from the road surface typically houses seat rails 450, auxiliary instrument panel 420, air duct 430, low-voltage wiring harness 440, etc.

[0054] When the vehicle is in motion, the vehicle floor 400 and the body structural components mounted on the floor 400 are prone to resonance. The vibration of the body structural components will transmit noise into the vehicle, resulting in excessive noise or abnormal noises inside the vehicle, thus affecting the consumer's driving experience.

[0055] Therefore, how to efficiently absorb the energy generated by vehicle vibration during driving, thereby reducing noise transmitted into the vehicle and improving the driving experience for consumers, is a technical problem that urgently needs to be solved.

[0056] In view of this, the present application provides a vibration-absorbing device for vehicles, in which a damping component 210 is disposed within a mass component 100, and a first support component 220 and a second support component 230 connect the damping component 210 to the vehicle floor 400. The damping component 210 efficiently absorbs energy generated during vehicle operation, while the mass component 100 reduces the vehicle vibration amplitude, thereby reducing noise transmitted into the vehicle body during operation and improving the driving experience. Furthermore, by changing the weight and size of the mass component 100, the device can meet the vibration amplitude requirements of different frequencies, improving the frequency coverage and versatility of the vibration-absorbing device provided in this application. The detachable connection between the damping component 200 and the vehicle floor 400 enhances the installation flexibility of the vibration-absorbing device.

[0057] The following description, in conjunction with the accompanying drawings and embodiments, further illustrates a vibration-absorbing device for vehicles provided in this application.

[0058] See Figure 1 , Figure 2 , Figure 3 and Figure 4 This application provides a vibration-absorbing device for a vehicle, which includes a mass component 100 and a vibration damping assembly 200. The vibration damping assembly 200 includes a vibration damping member 210, a first support member 220, and a second support member 230.

[0059] The mass component 100 has an assembly portion 110 extending through both opposite sides of the mass component 100 in the thickness direction. At least a portion of the damping element 210 is disposed within the assembly portion 110. The assembly portion 110 provides space for the installation and positioning of the damping element 210. The damping element 210 may be entirely located within the assembly portion 110, or a portion of the damping element 210 may be located within the assembly portion 110, with the remainder extending outside the assembly portion 110.

[0060] The vibration damper 210 has a mounting channel 211, which has a first end 2111 and a second end 2112 in the extending direction. At least a portion of the first support member 220 is disposed in the first end 2111, and the first support member 220 has a first mounting portion 221. At least a second support member 230 is disposed in the second end 2112, and the second support member 230 has a second mounting portion 231.

[0061] The vibration damping assembly 200 can be detachably mounted on the vehicle floor 400 via the first mounting portion 221 and the second mounting portion 231. Therefore, the vibration damping assembly 200 can be flexibly positioned at locations on the vehicle floor 400 where vibration occurs, without requiring modifications to the vehicle body structure, thus improving the installation flexibility of the vibration absorption device. Furthermore, when the vibration damper 210 needs to be replaced, the entire vibration absorption device does not need to be replaced, making disassembly simple.

[0062] In this application, the location and number of the vibration damping components 200 on the vehicle floor 400 are not further limited, as long as the vibration damping requirements of the vehicle are met.

[0063] During vehicle operation, vibrations occur due to factors such as the operation of the power system, tire movement, and road surface bumps. The vehicle maintains its natural frequency of vibration, which is first transmitted to the vehicle floor 400, then to the first mounting portion 221 and the second mounting portion 231, and subsequently to the first support member 220 and the second support member 230. Since the first support member 220 and the second support member 230 are located within the mounting channel 211 of the vibration damper 210, meaning they are in close contact with the vibration damper 210, they transmit vibrations to the vibration damper 210. The vibration damper 210 absorbs some of the energy generated by the vibration, thereby reducing noise transmitted into the vehicle body during operation and improving the driving experience.

[0064] For example, the damper 210 may be an elastic element. When the first support 220 and the second support 230 transmit vibrations to the elastic element, the elastic element undergoes elastic deformation, thereby absorbing the energy generated by the vibration.

[0065] The residual vibration generated after the damper 210 absorbs part of the vibration is transmitted to the mass 100, driving the mass 100 to move and causing it to resonate and vibrate at the same frequency. However, based on the principle of inertia, the mass 100 has a certain weight. When the mass 100 changes from a static state to a moving state, it generates a reaction force opposite to the phase of the vibration. This reaction force is fed back to the floor 400 through the damper 210, the first support 220, and the second support 230. Since this reaction force is opposite to the phase of the vibration, it can counteract and suppress the vibration of the vehicle floor 400, thereby further achieving the effect of vibration reduction, reducing the noise transmitted to the vehicle body during vehicle operation, and improving the driving experience.

[0066] For example, during one vibration cycle, along the vehicle height direction, when the floor 400 moves towards the interior of the vehicle, the floor 400 causes the mass component 100 to accelerate towards the interior of the vehicle. The mass component 100 generates a reaction force in the opposite direction, which acts on the floor 400. When the floor 400 moves towards the road surface, the floor 400 causes the mass component 100 to accelerate towards the road surface. The mass component 100 generates a reaction force in the opposite direction, which acts on the floor 400. The reaction force is opposite to the vibration phase, thereby effectively counteracting the vehicle's vibration.

[0067] The weight of the mass component 100 determines the magnitude of the reaction force. The greater the weight of the mass component 100, the greater the reaction force. Therefore, mass components 100 of different weights or sizes can be selected according to the different vibration frequencies of different vehicles, so that the mass component 100 generates a reaction force that matches its vibration, effectively reducing vehicle vibration, reducing noise transmitted into the vehicle body during driving, and improving the driving experience. Furthermore, by replacing different mass components 100, different vehicles can be adapted, thereby improving the frequency coverage and versatility of the vibration absorption device.

[0068] This application provides a vibration-absorbing device for a vehicle. A mass member 100 has an assembly portion 110, allowing at least a portion of a vibration damper 210 to be disposed within the mass member 100. The mass member 100 contacts the vibration damper 210, enabling the vibration damper 210 to absorb energy generated by vehicle vibrations. The vibration damper 210 has a mounting channel 211, which extends to have a first end 2111 and a second end 2112. At least a portion of a first support member 220 is disposed within the first end 2111, and at least a portion of a second support member 230 is disposed within the second end 2112, such that the first support member 220 and the second support member 230 are respectively connected to the vibration damper 210. The first support member 220 has a first mounting portion 221, and the second support member 230 has a second mounting portion 231. Both the first mounting portion 221 and the second mounting portion 231 are used to connect with the vehicle floor 400, thereby enabling the vibration damping assembly 200 and the vehicle floor 400 to be detachably connected, making disassembly convenient and improving the installation flexibility of the vibration damping device.

[0069] When the vehicle floor 400 vibrates, the energy generated by the vibration is transmitted to the damping member 210 through the first mounting part 221 and the second mounting part 231. The damping member 210 can efficiently absorb the energy generated during vehicle operation, thereby reducing the noise transmitted to the vehicle body during vehicle operation and improving the driving experience.

[0070] Furthermore, through contact with the damping component 210, some vibration is transmitted to the mass component 100. The mass component 100 can generate a counterforce against the vibration, thereby significantly reducing the vibration amplitude and further reducing noise transmitted to the vehicle body during driving, thus improving the driving experience. When the weight and size of the mass component 100 are different, the magnitude of the counterforce generated by the mass component 100 against the vibration is different, and the reduction in vibration amplitude is different. The vibration absorption device for vehicles provided in this application embodiment has a simple structure and can meet the vibration amplitude requirements of different frequencies by changing the weight and size of the mass component 100, thereby improving the frequency coverage and versatility of the vibration absorption device provided in this application embodiment.

[0071] Therefore, an embodiment of this application provides a vibration-absorbing device for a vehicle, comprising a mass component 100 and a vibration damping assembly 200. A vibration damping component 210 is disposed within the mass component 100, and a first support component 220 and a second support component 230 detachably connect the vibration damping component 210 to the vehicle floor 400. The vibration damping component 210 efficiently absorbs energy generated during vehicle operation, while the mass component 100 reduces vehicle vibration amplitude, thereby reducing noise transmitted into the vehicle body during operation and improving the driving experience. Furthermore, by changing the weight and size of the mass component 100, the device can meet the vibration amplitude requirements of different frequencies, improving the frequency coverage and versatility of the vibration-absorbing device provided in this application embodiment. The detachable connection of the vibration damping assembly 200 to the vehicle floor 400 enhances the installation flexibility of the vibration-absorbing device.

[0072] See Figure 4 In some embodiments, the first support member 220 and the second support member 230 are connected at their close ends.

[0073] For example, the second support member 230 is connected to the floor 400 via the second mounting portion 231, and the first support member 220 is connected to the auxiliary instrument 420 via the first mounting portion 221. The first support member 220 and the second support member 230 are connected at their close ends and are disposed within the mounting channel 211. When the floor 400 vibrates, the vibration is directly transmitted to the first support member 220 via the second support member 230, thereby causing the vibration damper 210 to deform, allowing the vibration damper 210 to absorb the energy generated by the vibration.

[0074] The first support member 220 and the second support member 230 are connected at their close ends to form a single integrated support member, resulting in higher structural strength and the ability to resist complex stresses during vehicle operation, thus reducing the risk of structural damage to the shock-absorbing device. Furthermore, the integrated support member 220 and the second support member 230 enhance the stability of the movement of the damper 210 and the mass member 100, preventing unnecessary swaying or wear, thereby extending the service life of the shock-absorbing device.

[0075] See Figure 4 In some embodiments, the first support member 220 and the second support member 230 are interlocked at their close ends.

[0076] For example, the first support member 220 may have a groove at the end near the second support member 230, and the second support member 230 may have a corresponding protrusion at the end near the first support member 220. The first support member 220 and the second support member 230 are connected by the groove and the protrusion cooperating with each other.

[0077] For example, the first support 220 and the second support 230 may be bushings.

[0078] By interlocking the first support member 220 and the second support member 230 at their close ends, the first support member 220 and the second support member 230 have extremely high coaxiality, thereby making the energy transmission generated by vibration more uniform and avoiding unnecessary swaying or wear of the damping member 210 and the mass member 100, thus enhancing the service life of the shock absorption device.

[0079] See Figure 4 In some embodiments, the mounting channel 211 has an inner wall 2113, and the circumferential outer wall of at least one of the first support member 220 and the second support member 230 is connected to the inner wall 2113.

[0080] For example, the outer circumferential wall of the first support member 220 may be connected to the inner wall 2113 of the channel, the outer circumferential wall of the second support member 230 may be connected to the inner wall 2113 of the channel, or both the outer circumferential walls of the first support member 220 and the second support member 230 may be connected to the inner wall 2113 of the channel. When the vehicle floor 400 vibrates, the vibration is directly transmitted to the damping member 210 through the first support member 220 and the second support member 230.

[0081] By connecting the circumferential outer wall of at least one of the first support member 220 and the second support member 230 to the inner wall 2113 of the channel, vibration can be efficiently transmitted to the damping member 210, reducing the loss of vibration energy, thereby ensuring accurate prediction of the frequency of vibration of the vehicle and selecting a vibration absorption device that is compatible with the vehicle vibration frequency to improve the stability of the vibration absorption device.

[0082] In some embodiments, the assembly portion 110 is an assembly hole, and the circumferential outer wall of the damping member 210 has a protrusion 212 protruding toward the side of the mass member 100, and the protrusion 212 contacts the hole wall of the assembly hole.

[0083] For example, the damper 210 can be a rubber damper 210, which is clearance-fitted with the wall of the mounting hole via a protrusion 212. When the vehicle vibrates, the vibration is transmitted to the damper 210, causing it to deform. The protrusion 212 serves as the contact point between the damper 210 and the mounting portion 110. The protrusion 212 can move along the wall of the mounting hole, guiding the damper 210 to deform, thereby enabling it to absorb vibration and reduce noise transmitted into the vehicle body during driving, thus improving the driving experience.

[0084] See Figure 4 In some embodiments, the number of protrusions 212 is at least two, and the protrusions 212 are spaced apart on the circumferential outer wall of the damper 210 along the depth direction of the mounting hole.

[0085] For example, two protrusions 212 are provided at intervals on the circumferential outer wall of the damper 210 along the depth direction of the mounting hole. Each protrusion 212 contacts the wall of the mounting hole, and the area between the two protrusions 212 does not contact the wall of the mounting hole, thus providing deformation space for the damper 210.

[0086] When the damper 210 vibrates, in the area outside the two protrusions 212, the damper 210 is not constrained by the mounting holes and has space to deform freely, which makes the deformation of the damper 210 easier and has a better vibration absorption effect, thereby reducing the noise transmitted to the vehicle body during vehicle operation and improving the driving experience.

[0087] See Figure 4In some embodiments, the circumferential outer wall of the damper 210 further has a first limiting portion 213 and a second limiting portion 214 protruding toward the mass member 100. The first limiting portion 213 is located in the region of the damper 210 where the first support member 220 is provided, and at least a portion of the first limiting portion 213 is located outside the assembly portion 110 and abuts against the mass member 100. The second limiting portion 214 is located in the region of the damper 210 where the second support member 230 is provided, and at least a portion of the second limiting portion 214 is located outside the assembly portion 110 and abuts against the mass member 100.

[0088] For example, the first limiting part 213 and the second limiting part 214 can be connected to the mass member 100 by adhesive. When the vehicle experiences severe vibration, the first limiting part 213 and the second limiting part 214 ensure that the damping member 210 remains connected to the mass member 100, preventing the damping member 210 and the mass member 100 from falling off. This ensures the damping effect of the vibration absorption device while improving its stability.

[0089] In some embodiments, both the first limiting portion 213 and the second limiting portion 214 are annular structures. Both the first limiting portion 213 and the second limiting portion 214 maintain contact with the mass member 100. By having both the first limiting portion 213 and the second limiting portion 214 as annular structures, the uniformity of the force on the first limiting portion 213 and the second limiting portion 214 is improved, ensuring the consistency of the limiting effect, thereby ensuring the stability of the vibration absorption device.

[0090] See Figure 2 In some embodiments, both the first mounting portion 221 and the second mounting portion 231 have mounting holes for the connector 300, which is connected to the floor 400, to pass through. The second mounting portion 231 is coaxially arranged with the first mounting portion 221 and communicates with it.

[0091] For example, the connector 300 can be a bolt. The second mounting portion 231 is coaxially arranged with and communicates with the first mounting portion 221. The bolt passes through the second mounting portion 231 and the first mounting portion 221, thereby fixing it to the floor 400. Through the connector 300, the entire vibration-absorbing device is connected to the floor 400 as a whole, and vibration can be directly transmitted to the vibration-absorbing device through the floor 400. When the vehicle vibrates, the vibration-absorbing device will not move, ensuring connection rigidity and the stability of the vibration-absorbing device.

[0092] See Figure 2 Secondly, this application also provides a vehicle. The vehicle includes a floor 400, a vibration-absorbing device and a connector 300 provided in any embodiment of this application, the vibration-absorbing device being disposed on the floor 400.

[0093] The connector 300 passes through the first mounting portion 221 and the second mounting portion 231 of the vibration-absorbing device and is detachably connected to the floor 400. The floor 400, the vibration-absorbing device, and the connector 300 have all been described above and will not be repeated here.

[0094] Since the vehicle provided in this application includes the vibration-absorbing device provided in any embodiment of this application, the vehicle provided in this application has the same effect, namely, it can reduce the noise transmitted to the vehicle body during vehicle operation and improve the driving experience. Furthermore, by changing the weight and size of the mass component 100, it meets the vibration amplitude requirements of different frequencies, thereby improving the frequency coverage and versatility of the vibration-absorbing device provided in this application embodiment. The detachable connection between the vibration damping component 200 and the vehicle floor 400 improves the installation flexibility of the vibration-absorbing device.

[0095] The sequence numbers of the embodiments in this application are for descriptive purposes only and do not represent the superiority or inferiority of the embodiments. The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
