Description

Technical Field

[0001] This utility model belongs to the field of automotive assembly technology, and in particular relates to a suspension locking structure and a vehicle. Background Technology

[0002] As an important means of transportation, automobiles play an irreplaceable role in people's daily lives. Automobiles typically consist of a frame, body, powertrain, and control system. In existing technologies, to reduce vibration transmission, isolate noise, reduce mechanical fatigue, and isolate road impacts, the powertrain is mounted to the frame via suspension.

[0003] During the installation of powertrain mounts, bolts are typically used to connect them to the vehicle frame to ensure their firmness and reliability. However, this method suffers from problems such as loosening, assembly difficulties, and low assembly efficiency. In the prior art, patent CN215284347U, entitled "Powertrain Mount and Vehicle," discloses a mounting fastening method that uses a retractable stop block on the housing. This stop block, when extended from the housing, prevents the mount assembly from disengaging, achieving fastening through a snap-fit ​​mechanism, thus solving the problems associated with bolt fastening.

[0004] However, the suspension assembly is only connected by a stop block, and the fastening strength is still insufficient. Furthermore, the reaction force generated by the suspension is concentrated on the stop block, which is prone to rapid metal fatigue, making it difficult to guarantee long-term reliability. Utility Model Content

[0005] This utility model solves, to at least a certain extent, one of the technical problems in the related art.

[0006] Therefore, this application aims to provide a suspension locking structure and vehicle, which is intended to improve the strength of suspension fastening and delay metal fatigue of the fastening structure by means of a new structural design of the fastening connection between the suspension and the frame, thereby solving the technical problems of insufficient fastening strength and difficulty in guaranteeing long-term reliability in the prior art when using stop blocks for fastening.

[0007] To achieve the above objectives, in a first aspect, this utility model provides a suspension locking structure, comprising:

[0008] It includes:

[0009] Suspension frame, used to connect the powertrain;

[0010] Locking assembly for connecting the suspension frame to the vehicle frame, the locking assembly comprising:

[0011] A locking seat is disposed on the suspension frame and is used to be inserted into the locking hole of the frame; the locking seat is provided with a first locking cavity;

[0012] A first locking tongue is disposed in the first locking cavity, and the first locking tongue is used to extend into or retract into the first locking cavity;

[0013] The second locking tongue is used to be disposed in the locking hole of the frame. The second locking tongue is used to extend into the locking hole or retract into the second locking cavity of the frame.

[0014] A first elastic element is disposed within the locking seat. The first elastic element is connected to the first locking tongue and is used to drive the first locking tongue to move in the direction of extending out of the locking seat.

[0015] The locking seat is inserted into the locking hole such that the first locking cavity is aligned with the second locking cavity, the first locking tongue is engaged with the second locking tongue, the first elastic element drives the first locking tongue portion to extend into the second locking cavity, and the first locking tongue drives the second locking tongue portion to extend into the first locking cavity, so that the first locking tongue and the second locking tongue restrict the locking seat from disengaging from the locking hole.

[0016] In existing technologies, the housing mounted on the connecting bracket only uses a stop block to prevent the suspension assembly from detaching from the housing. This single component secures the suspension assembly, resulting in insufficient strength. However, this application, through the aforementioned solution, includes not only a first locking tongue within the first locking cavity of the locking seat, but also a second locking tongue within the second locking cavity of the frame, increasing the number of securing components. Therefore, compared to existing technologies, the strength of the suspension fastening is improved. Furthermore, the movement between the first and second locking tongues allows for the fastening of multiple components, reducing assembly difficulty and improving assembly efficiency.

[0017] Furthermore, in existing technologies, vibrations generated by the powertrain during operation, which is mounted on the suspension assembly, are transmitted to the stop block through the suspension assembly. Impacts from road undulations on the vehicle are also transmitted to the suspension assembly through the stop block, causing the reaction force generated by the suspension assembly to act on the stop block. The stop block bears significant forces from both sides. Since metal fatigue is positively correlated with both the magnitude and frequency of force applied to components, under constant force frequency conditions, the support block bears a large force, making it prone to rapid metal fatigue. In this application, fastening is achieved through a first and second locking tongue. Multiple fastening components share the forces from both sides, reducing the force on each fastening component and thus slowing down the rate of metal fatigue in the fastening components, improving long-term reliability. Furthermore, by inserting the locking seat into the locking hole, the first elastic element drives the first locking tongue to engage with the second locking cavity, and the second locking tongue engages with the first locking tongue in turn, thus achieving mutual engagement between the locking seat and the vehicle frame. The structure is compact, allowing for efficient use of space in the engine compartment, convenient installation, and improved production efficiency. No additional assembly tools are required, saving on overall vehicle development costs. The first and second locking tongues are stably engaged in their respective locking cavities, eliminating the need to consider torque issues compared to bolt tightening.

[0018] In some embodiments of this application, the second locking tongue is rotatably disposed within the second locking cavity, so that when the first locking tongue pushes one end of the second locking tongue away from the locking seat, the other end of the second locking tongue can be screwed into the first locking cavity toward the locking seat.

[0019] In the technical solution, the rotational installation method simplifies the structure of the locking assembly, makes it easier for the second locking tongue to extend into the first locking cavity, and makes the locking assembly simpler and more compact.

[0020] In some embodiments of this application, a second elastic member is further included; the second elastic member is disposed in the second locking cavity and connected to the second locking tongue; the second elastic member is used to drive the side of the second locking tongue away from the opening of the locking hole to move in the direction of extending into the locking hole, so that the side of the second locking tongue near the opening of the locking hole is completely located in the second locking cavity.

[0021] In the technical solution, compared to the second locking tongue passively extending into the first locking cavity, the second locking tongue can actively extend into the first locking cavity for fastening under the drive of the second elastic element. This improves the smoothness of the coordinated movement of the first and second locking tongues and enhances the stability of the fastening and locking of the first and second locking tongues.

[0022] In some embodiments of this application, the first locking tongue is connected to an operating arm, which extends beyond the locking seat; the first elastic member is an elastic tension member, one end of which is connected to the locking seat and the other end of which is connected to the operating arm.

[0023] In the technical solution, the operating arm provides a connection position for the first elastic element, and at the same time, the extension of the operating arm provides an operating position for unlocking the locking component, which not only reduces the cost and time during maintenance and disassembly, but also simplifies the structure.

[0024] In some embodiments of this application, both the first latch and the second latch are semi-cylindrical so that they can be combined into a cylinder.

[0025] The inner walls on one side of the first locking cavity and the inner walls on one side of the second locking cavity are both arc-shaped, so as to match the first locking tongue and the second locking tongue respectively.

[0026] In the technical solution, the first and second locking tongues can be rotated and installed by means of arc-shaped matching, which improves the stability and compactness of the assembly. After the first and second locking tongues drive each other, they can maintain close contact with the second locking cavity and the first locking cavity respectively, avoiding gaps during fastening and improving the stability of fastening.

[0027] In some embodiments of this application, the locking seat is provided with a first mounting groove, and a first partition is provided in the first mounting groove. The first partition divides the internal space of the first mounting groove into a first mounting cavity and a first locking cavity, and a through groove is provided on the first partition.

[0028] The first locking tongue is rotatably mounted in the first locking cavity, and the first elastic element is located in the first mounting cavity.

[0029] In this technical solution, the locking seat is hollow, creating space to accommodate the first bolt and the first elastic element, ensuring a compact locking assembly and reducing its weight. The through slot provides movement space for the operating arm connected to the first bolt and also provides a channel for the operating arm to enter the first mounting cavity, enabling the first elastic element to drive the first bolt within the locking seat and ensuring the compactness of the locking assembly.

[0030] In some embodiments of this application, the locking assembly further includes a first cover; the first cover is mounted on the locking seat to close the first mounting groove;

[0031] The first cover is provided with a first column, and the first locking tongue is provided with a first processing groove. The first column is inserted into the first processing groove so that the first locking tongue rotates around the first column.

[0032] In this technical solution, the structure ensures the installation stability of the first locking tongue and the first elastic element, while also enabling the rotational installation of the first locking tongue and reducing the processing difficulty of the parts.

[0033] In some embodiments of this application, the locking assembly further includes an insert housing for being disposed in a mounting hole in the frame, and the second locking tongue is disposed in the insert housing.

[0034] In the technical solution, the insert box improves the ease of assembling the second latch, and at the same time makes the matching structure of the second latch easier to process.

[0035] In some embodiments of this application, the insert box is provided with a second mounting groove, a second partition is provided in the second mounting groove, the second partition divides the internal space of the second mounting groove into a second mounting cavity and a second locking cavity, and a through groove is provided on the second partition.

[0036] The second locking tongue is rotatably installed in the second locking cavity. The second locking tongue is connected to a fastening support arm, which extends into the second mounting cavity through the through groove. A second elastic element is installed in the second mounting cavity. The second elastic element is an elastic compression element, one end of which is connected to the insert box and the other end of which is connected to the fastening support arm.

[0037] In this technical solution, the structure is easier to manufacture when mounted on the insert housing, and it creates space to accommodate the second latch and the second elastic element, ensuring the compactness of the locking assembly and reducing its weight. The through slot provides room for the fastening arm connected to the second latch and also provides a channel for the fastening arm to pass into the second mounting cavity, enabling the second elastic element to drive the connection between the first latch and the locking seat, thus ensuring the compactness of the locking assembly.

[0038] In some embodiments of this application, the locking assembly further includes a second cover; the second cover is mounted on the insert housing to close the second mounting groove; and the second cover is used to close the mounting hole of the frame;

[0039] The second cover is provided with a second column, and the second latch is provided with a second processing groove. The second column is inserted into the second processing groove so that the second latch rotates around the second column.

[0040] In the technical solution, the structure can ensure the installation stability of the second locking tongue and the second elastic element, while realizing the rotational installation of the second locking tongue, reducing the processing difficulty of the parts, and providing a seal for the assembly hole, thereby improving the installation stability of the insert box.

[0041] In addition, this application also provides a suspension locking structure, which includes:

[0042] Suspension frame, used to connect the powertrain;

[0043] Locking assembly for connecting the suspension frame to the vehicle frame, the locking assembly comprising:

[0044] A locking seat is disposed on the suspension frame and is used to be inserted into the locking hole of the frame; the locking seat is provided with a first locking cavity;

[0045] A first locking tongue is disposed in the first locking cavity, and the first locking tongue is used to extend into or retract into the first locking cavity;

[0046] The second locking tongue is used to be disposed in the locking hole of the frame. The second locking tongue is used to extend into the locking hole or retract into the second locking cavity of the frame.

[0047] A first elastic element is disposed in the second locking cavity. The first elastic element is connected to the second locking tongue and is used to drive the second locking tongue to move in the direction of extending out of the second locking cavity.

[0048] The locking seat is inserted into the locking hole such that the first locking cavity is aligned with the second locking cavity, the first locking tongue is engaged with the second locking tongue, the first elastic element drives the second locking tongue portion to extend into the first locking cavity, and the second locking tongue drives the first locking tongue portion to extend into the second locking cavity, so that the first locking tongue and the second locking tongue restrict the locking seat from disengaging from the locking hole.

[0049] In existing technologies, the housing mounted on the connecting bracket only uses a stop block to prevent the suspension assembly from detaching from the housing. This single component secures the suspension assembly, resulting in insufficient strength. However, this application, through the aforementioned solution, includes not only a first locking tongue within the first locking cavity of the locking seat, but also a second locking tongue positioned within a locking hole in the vehicle frame, increasing the number of securing components. Therefore, compared to existing technologies, the strength of the suspension fastening is improved. Furthermore, the movement between the first and second locking tongues allows for the fastening of multiple components, reducing assembly difficulty and improving assembly efficiency.

[0050] Furthermore, in existing technologies, vibrations generated by the powertrain during operation, which is mounted on the suspension assembly, are transmitted to the stop block through the suspension assembly. Impacts from road undulations on the vehicle are also transmitted to the suspension assembly through the stop block, causing the reaction force generated by the suspension assembly to act on the stop block. The stop block bears significant forces from both sides, making it prone to rapid metal fatigue. In this application, however, the first and second locking tongues are used for fastening, with multiple fastening components sharing the forces from both sides. This reduces the stress on each fastening component, slows down the rate of metal fatigue in the fastening components, and improves long-term reliability.

[0051] In addition, this application also provides a vehicle, the vehicle comprising:

[0052] Frame;

[0053] Powertrain;

[0054] The suspension locking structure described above;

[0055] The powertrain is mounted on the suspension frame of the suspension locking structure, and the suspension locking structure is mounted on the vehicle frame.

[0056] The technical solution improves the stability of the powertrain mount installation during vehicle operation by using a new type of mount locking structure, and also enhances the long-term reliability of the powertrain mount installation.

[0057] In some embodiments of this application, a suspension bushing is mounted on the suspension frame, the powertrain is connected to the suspension bushing, and the suspension bushing is an elastic element.

[0058] In the technical solution, the powertrain is installed through elastic components, which reduces the vibration transmitted to the suspension locking structure, further reduces the stress on the first and second locking tongues, delays metal fatigue of the first and second locking tongues, and improves long-term reliability.

[0059] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0087] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0088] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0089] In this utility model, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Furthermore, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0090] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0091] In this application, the vehicle includes a frame 1 and a powertrain 2. Based on power type, vehicles are classified into three types: electric, gasoline, and hybrid. The powertrain 2 of an electric vehicle includes an electric motor; the powertrain 2 of a gasoline vehicle includes an engine, transmission, and drive axle; the powertrain 2 of a hybrid vehicle includes not only an electric motor and engine, but may further include a transmission and drivetrain system. The powertrain 2 generates vibrations during operation. If it is directly and rigidly connected to the frame 1, these vibrations will be transmitted to the vehicle body and converted into noise, causing significant discomfort to passengers inside the vehicle. Furthermore, when the vehicle encounters bumps or road impacts, the direct rigid connection to the powertrain 2 means that vibrations and impacts will be directly transmitted to the powertrain 2, leading to metal fatigue, loose bolts, or even breakage.

[0092] To reduce vibration transmission, isolate noise, and protect component lifespan, while also providing support and positioning, adapting to dynamic operating conditions, and balancing vibrations of different frequencies, the powertrain 2 is mounted via a suspension assembly, meaning the powertrain 2 is mounted to the frame 1. The elastic components in the suspension assembly effectively absorb and isolate vibration energy, reducing the amplitude of vibrations transmitted to the vehicle body, improving ride comfort, and indirectly reducing noise transmission into the vehicle interior, improving cabin quietness. It also absorbs some impacts from the road surface, preventing direct transmission to the powertrain 2. The suspension assembly bears the static load of the powertrain 2, preventing component sagging or displacement. During rapid acceleration or deceleration, the torque output from the engine and / or electric motor generates a reaction force, causing the powertrain 2 to twist in the opposite direction. The suspension system balances these dynamic forces through a specific directional design stiffness (such as a "soft-hard" combination suspension), preventing excessive component sway. The engine and / or electric motor generate vibrations of different frequencies at different speeds; the damping characteristics of the suspension system cover vibration reduction requirements under all operating conditions.

[0093] In the following, embodiments of this application will be described in detail with reference to the accompanying drawings.

[0094] Referring to all the accompanying drawings, in one schematic embodiment of the suspension locking structure of this utility model, the suspension locking structure includes a suspension frame 100, which is connected to the powertrain 2. In a vehicle, the suspension frame 100 is a component located in the vehicle's engine compartment. On one hand, the suspension frame 100, as part of the suspension assembly, provides fixation and support for the powertrain 2. On the other hand, the suspension frame 100 provides a position for mounting and fixing elastic components, enabling the elastic components to effectively absorb and isolate vibrations from the powertrain 2.

[0095] In some embodiments, the suspension locking structure further includes a locking component 200, a portion of which is disposed on the suspension frame 100 and another portion of which is disposed on the vehicle frame 1. The locking component 200 securely connects the suspension frame 100 to the vehicle frame 1, thereby allowing the powertrain 2 to be mounted on the vehicle frame 1 via the suspension frame 100.

[0096] Reference Figures 2 to 3 as well as Figures 15 to 18 In some embodiments, the locking assembly 200 includes a locking seat 201. The locking seat 201 is disposed at one end of the suspension frame 100 near the frame 1. The frame 1 has a locking hole 101, the opening of which is located on the side of the frame 1 near the suspension frame 100. The locking seat 201 connects the suspension frame 100 to the frame 1. During installation, the suspension frame 100 can be inserted into the locking hole 101 simply to position and connect it to the frame 1, facilitating assembly and improving production efficiency.

[0097] The end of the locking seat 201 near the locking hole 101 can be set as a tapered structure. During the process of inserting the locking seat 201 into the locking hole 101, the tapered structure can guide the locking seat 201 to align with the center of the locking hole 101, so as to smoothly insert it into the locking hole 101 and improve the accuracy and convenience of positioning and installation.

[0098] The locking seat 201 is provided with a first locking cavity 202, which is a chamber inside the locking seat 201. The first locking cavity 202 has an opening, through which a component installed in the first locking cavity 202 can extend out of the first locking cavity 202 to the outside of the locking seat 201 or retract into the first locking cavity 202.

[0099] In another embodiment, the locking seat 201 can also be disposed on the frame 1, and the locking hole 101 is formed on the suspension frame 100. The locking seat 201 is inserted into the locking hole 101 of the suspension frame 100, thereby fixing the frame 1 to the suspension frame 100 by plugging it in. This design changes the plugging connection relationship between the suspension frame 100 and the frame 1, making manufacturing and assembly more flexible.

[0100] Reference Figure 2 , Figures 4 to 5 as well as Figures 15 to 18 In some embodiments, the locking assembly 200 further includes a first locking tongue 203, which is disposed in the first locking cavity 202. The first locking tongue 203 extends out of the first locking cavity 202 to the locking seat 201 or retracts into the first locking cavity 202 through the opening of the first locking cavity 202.

[0101] At least two guide surfaces may be provided on the inner wall of the first locking cavity 202. Both guide surfaces are planar and parallel to each other. The guide surfaces extend to the opening of the first locking seat 201. The first locking tongue 203 is located between the two guide surfaces, and each guide surface slides in cooperation with the surface of the corresponding side of the first locking tongue 203, so that the multiple guide surfaces form a guide groove. The first locking tongue 203 translates by sliding along the guide groove, thereby enabling the first locking tongue 203 to extend out of the first locking cavity 202 and outside the locking seat 201 or retract into the first locking cavity 202.

[0102] A guide rail can also be installed inside the first locking cavity 202. The first locking tongue 203 is slidably installed on the guide rail. Guided by the guide rail, the first locking tongue 203 can slide towards the opening of the first locking cavity 202 or slide away from the opening of the first locking cavity 202. This allows the first locking tongue 203 to extend out of the first locking cavity 202 and out of the locking seat 201 or retract into the first locking cavity 202.

[0103] With the above design, the first locking tongue 203 extends or retracts in a translational manner, which is simple in structure and ensures that the first locking tongue 203 has sufficient travel.

[0104] A rotating shaft can also be provided inside the first locking seat 201. The first locking tongue 203 is rotatably installed on the rotating shaft. The first locking tongue 203 rotates around the rotating shaft, so that a part of the first locking tongue 203 is rotated out of the first locking cavity 202 or retracted into the first locking cavity 202, so that the first locking tongue 203 extends out of the first locking cavity 202 to the outside of the locking seat 201 or retracts into the first locking cavity 202.

[0105] The inner wall of the first locking cavity 202 away from the opening can be set to be arc-shaped, and the side of the first locking tongue 203 away from the opening of the first locking cavity 202 is also arc-shaped, so that the first locking cavity 202 and the first locking tongue 203 match on the side away from the opening of the first locking cavity 202. The two slide relative to each other to realize the rotation of the first locking tongue 203, so that a part of the first locking tongue 203 can be rotated out of the first locking cavity 202 or retracted into the first locking cavity 202, so that the first locking tongue 203 extends out of the first locking cavity 202 to the locking seat 201 or retracts into the first locking cavity 202.

[0106] With the above design, the first locking tongue 203 extends or retracts in a rotating manner, which reduces the space occupied by the first locking tongue 203. At the same time, the rotation of a part of the first locking tongue 203 will cause the other part to retract more deeply, which facilitates the entry of other components into the first locking cavity 202.

[0107] Reference Figure 2 as well as Figures 15 to 18In some embodiments, the locking assembly 200 further includes a first elastic element 204 disposed within the locking seat 201. The first elastic element 204 is connected to the first latch 203, and the elastic force generated by the first elastic element 204 drives the first latch 203 to move in a direction extending out of the locking seat 201, thereby extending the first latch 203 out of the first locking cavity 202 beyond the locking seat 201. An elastic element is a component that can undergo elastic deformation under the action of external force and return to its original shape after the external force is removed. Elastic elements may include, but are not limited to, springs, rubber, elastic plastics, elastic metal sheets, etc.

[0108] The frame 1 is provided with a second locking cavity 205, which is a chamber inside the frame 1. The second locking cavity 205 has an opening, which is located on the inner wall of the locking hole 101. The locking seat 201 is inserted into the locking hole 101, and the first locking cavity 202 is aligned with the second locking cavity 205, so that the opening of the first locking cavity 202 is aligned with the opening of the second locking cavity 205. The first elastic element 204 drives the first locking tongue 203 to extend out of the first locking cavity 202 through the opening of the first locking cavity 202 to the outside of the locking seat 201, and further extend into the second locking cavity 205 through the opening of the second locking cavity 205, thereby engaging with the frame 1 and preventing the locking seat 201 from disengaging from the locking hole 101. This structural design allows the suspension frame 100 to be engaged with the frame 1 through the locking seat 201, realizing the assembly and fastening of the suspension frame 100, which is convenient for assembly and has high production efficiency.

[0109] The first elastic element 204 is an elastic tensioning element, with one end connected to the locking seat 201 and the other end connected to the first locking tongue 203. When the first locking tongue 203 moves away from the opening of the first locking cavity 202, it retracts into the first locking cavity 202, causing the first elastic element 204 to stretch and generate elastic force. This elastic force drives the first locking tongue 203 to move outward from the locking seat 201, thus extending the first locking tongue 203 beyond the first locking cavity 201.

[0110] The first elastic element 204 can also be an elastic compression element, with one end connected to the locking seat 201 and the other end connected to the first locking tongue 203. The first locking tongue 203 moves away from the opening of the first locking cavity 202, retracting into the first locking cavity 202, compressing the first elastic element 204 and generating elastic force. The elastic force generated by the compression of the first elastic element 204 drives the first locking tongue 203 to move outward from the locking seat 201, thus extending the first locking tongue 203 beyond the first locking cavity 201.

[0111] The above design enables the first elastic element 204 to drive the first locking tongue 203 to extend, and the structure is flexible.

[0112] Furthermore, when the locking seat 201 is not inserted into the locking hole 101, the first locking tongue 203 is in a state of extending out of the first locking cavity 202 beyond the locking seat 201, and the side surface of the first locking tongue 203 near the side wall of the locking seat 201 has an inclined guide surface. During the process of the locking seat 201 extending into the locking hole 101, the opening of the locking hole 101 contacts the guide surface of the first locking tongue 203 and slides on the guide surface of the first locking tongue 203, so that the locking hole 101 gradually pushes the first locking tongue 203 back into the first locking cavity 202. The first elastic element 204 is stretched or compressed to generate elastic force. The first locking cavity 202 is aligned with the second locking cavity 205, so that the opening of the first locking cavity 202 is aligned with the opening of the second locking cavity 205. The first locking tongue 203 is freed from the restraint of the inner wall of the locking hole 101. The first elastic element 204 drives the first locking tongue 203 to extend out of the first locking cavity 202 through the opening of the first locking cavity 202 to the outside of the locking seat 201, and further extends into the second locking cavity 205 through the opening of the second locking cavity 205, thereby locking onto the frame 1 and preventing the locking seat 201 from coming out of the locking hole 101. This structural design allows the locking seat 201 to be directly inserted into the locking hole 101 to complete the engagement with the frame 1, without the need for separate operation of the first locking tongue 203, making assembly convenient and production efficiency high.

[0113] Reference Figure 2 , Figures 6 to 7 as well as Figures 15 to 18 In some embodiments, the locking assembly 200 further includes a second locking tongue 206, which is disposed within the locking hole 101 of the frame 1. The second locking tongue 206 is located within a second locking cavity 205, and can extend from the second locking cavity 205 into the locking hole 101 or retract into the second locking cavity 205 through the opening of the second locking cavity 205.

[0114] Reference Figures 15 to 18The locking seat 201 is inserted into the locking hole 101, the first locking cavity 202 is aligned with the second locking cavity 205, so that the opening of the first locking cavity 202 is aligned with the opening of the second locking cavity 205, the first locking tongue 203 is engaged with the second locking tongue 206, and the first elastic member 204 drives a portion of the first locking tongue 203 to extend into the second locking cavity 205, thereby engaging with the frame 1; the portion of the first locking tongue 203 extending into the second locking cavity 205 pushes a portion of the second locking tongue 206, causing another portion of the second locking tongue 206 to extend out of the second locking cavity 205 and enter the first locking cavity 202, thereby engaging with the locking seat 201. Through this structural design, the frame 1 and the locking seat 201 are engaged with each other, increasing the number of fastening components to two, which not only improves the fastening stability but also reduces the stress on each fastening component, delaying or even avoiding metal fatigue. This structural design also allows the second locking tongue 206 to be linked with the first locking tongue 203, eliminating the need for independent operation of the second locking tongue 206, making assembly convenient and improving production efficiency.

[0115] In some embodiments, the second locking tongue 206 is rotatably disposed within the frame 1. The first locking tongue 203 partially extends into the second locking cavity 205, pushing one end of the second locking tongue 206 away from the locking seat 201. The second locking tongue 206 rotates, and the other end of the second locking tongue 206 moves towards the locking seat 201, thereby extending out of the second locking cavity 205 and entering the first locking cavity 202. This structural design simplifies the structure of the second locking tongue 206, allows for smooth engagement with the first locking tongue 203, and is easy to manufacture with low production costs.

[0116] In another embodiment, the second locking tongue 206 may include two pins and a transmission chain. The two pins are respectively connected to both ends of the transmission chain. The second locking cavity 205 is an integral U-shaped tubular structure. The first locking tongue 203 is attached to one pin, pushing it deeper into the second locking cavity 205. The transmission chain moves within the tubular second locking cavity 205 under the push of the pin, thereby pushing the other pin out of the second locking cavity 205 and engaging it with the locking seat 201. This structural design ensures the follow-up movement of the second locking tongue 206 and the engagement with the locking seat 201, providing diverse structural configurations for the second locking tongue 206.

[0117] Reference Figure 2 , Figure 10 as well as Figures 15 to 18In some embodiments, the locking assembly 200 further includes a second elastic member 207. The second elastic member 207 is disposed within the second locking cavity and connected to the second latch 206. The locking seat 201 is inserted into the locking hole 101, the first locking cavity 202 is aligned with the second locking cavity 205, and the second elastic member 207 drives the second latch 206 to move away from the opening of the locking hole toward the direction of insertion into the locking hole 101, so that the side of the second latch 206 near the opening of the locking hole 101 is completely located within the second locking cavity 205, or the side of the second latch 206 near the opening of the locking hole 101 is further retracted into the second locking cavity 205, providing space for the first latch 203 to extend into the second locking cavity 205, while simultaneously allowing the side of the second latch 206 away from the opening of the locking hole 101 to extend out of the second locking cavity 205 and further extend into the first locking hole 101 for engagement. This structural design enables the second locking tongue 206 to retract partially and extend partially. While moving in tandem with the first locking tongue 203, the second locking tongue 206 also has the ability to move independently, thus improving the secure engagement of the second locking tongue 206 and thereby enhancing the secure engagement between the locking seat 201 and the frame 1.

[0118] The second elastic element 207 is an elastic tension member, with one end connected to the frame 1 and the other end connected to the second locking tongue 206. The side of the second locking tongue 206 away from the opening of the locking hole 101 moves away from the locking seat 201, while the side of the second locking tongue 206 near the opening of the locking hole 101 moves towards the locking seat 201. The side of the second locking tongue 206 away from the opening of the locking hole 101 retracts into the second locking cavity 205, causing the second elastic element 207 to be stretched and generate elastic force. The elastic force generated by the second elastic element 207 drives the side of the second locking tongue 206 near the opening of the locking hole 101 to extend out of the second locking cavity 205 and drives the side of the second locking tongue 206 away from the opening of the locking hole 101 to retract deeper into the second locking cavity 205, thus enabling the second locking tongue 206 to extend into the first locking cavity 202 for engagement, while simultaneously providing space for the first locking tongue 203 to extend into the second locking cavity 205.

[0119] The second elastic element 207 can also be an elastic compression element, with one end connected to the frame 1 and the other end connected to the second locking tongue 206. The side of the second locking tongue 206 away from the opening of the locking hole 101 moves away from the locking seat 201, while the side of the second locking tongue 206 near the opening of the locking hole 101 moves towards the locking seat 201. The side of the second locking tongue 206 away from the opening of the locking hole 101 retracts into the second locking cavity 205, and the second elastic element 207 is compressed, generating elastic force. The elastic force generated by the second elastic element 207 drives the side of the second locking tongue 206 near the opening of the locking hole 101 to extend out of the second locking cavity 205, and drives the side of the second locking tongue 206 away from the opening of the locking hole 101 to retract deeper into the second locking cavity 205, thus enabling the second locking tongue 206 to extend into the first locking cavity 202 for engagement, while simultaneously providing space for the first locking tongue 203 to extend into the second locking cavity 205.

[0120] The above design enables the second elastic element 207 to drive the extension of the second locking tongue 206, and the structural configuration is flexible.

[0121] Furthermore, when the locking seat 201 is not inserted into the locking hole 101, the side of the second latch 206 away from the opening of the locking hole 101 is in a state of extending into the second locking cavity 205 and into the locking hole 101, and the surface of the second latch 206 near the locking seat 201 has an inclined guide surface. During the process of the locking seat 201 extending into the locking hole 101, the locking seat 201 contacts the guide surface of the second latch 206 and slides on the guide surface of the second latch 206, causing the locking seat 201 to gradually push the second latch 206 back into the second locking cavity 205. The second elastic element 207 is then stretched or compressed to generate elastic force, the first locking cavity 202 aligns with the second locking cavity 205, so that the opening of the first locking cavity 202 aligns with the opening of the second locking cavity 205. The second latch 206 is no longer restrained by the side wall of the locking seat 201, and the first latch 203 and... Driven by the second elastic element 207, the side of the second locking tongue 206 away from the opening of the locking hole 101 extends out of the second locking cavity 205 through the opening of the second locking cavity 205, and further extends into the first locking cavity 202 through the opening of the first locking cavity 202, thereby engaging with the locking seat 201 and preventing the locking seat 201 from disengaging from the locking hole 101; at the same time, the side of the second locking tongue 206 near the opening of the locking hole 101 retracts deeper into the second locking hole 101, causing a portion of the first locking tongue 203 to extend into the second locking hole 101, thereby engaging with the frame 1. This structural design allows the locking seat 201 to be directly inserted into the locking hole 101 to complete the engagement with the frame 1, without the need for separate operation of the second locking tongue 206, making assembly convenient and production efficiency high.

[0122] Reference Figure 2 , Figures 4 to 5 as well as Figures 15 to 18In some embodiments, the first locking tongue 203 is connected to an operating arm 208, which extends beyond the locking seat 201. One end of the operating arm 208 extending beyond the locking seat 201 is located inside the vehicle's engine compartment, outside the frame 1 and suspension frame 100. An operator can directly or manually operate the operating arm 208, either directly or with tools, to drive the first locking tongue 203. During maintenance and disassembly, an extended sleeve is inserted into the engine compartment and fitted onto the extended end of the operating arm 208. Moving the extended sleeve moves the operating arm 208, causing it to overcome the elastic force generated by the first elastic element 204 and retract the first locking tongue 203 completely into the first locking hole 101. Simultaneously, the first locking hole 101 drives the second locking tongue 206, which is in contact with it. This causes the second locking tongue 206 to overcome the elastic force generated by the second elastic element 207 and retract completely into the second locking hole 101, eliminating the jamming between the first and second locking tongues 203 and 206. The locking seat 201 is then pulled out of the locking hole 101, and the suspension frame 100 is removed from the frame 1. This structural design improves the convenience of maintenance and disassembly operations and requires simple tools. A through slot 212 is provided on the locking seat 201 and / or the suspension frame 200 to allow the operating arm 208 to extend and move with the first locking tongue 203.

[0123] The first elastic element 204 is an elastic tension member, with one end connected to the locking seat 201 and the other end connected to the operating arm 208. This structural design allows the operating arm 208 to function as a component for external operation of the first latch 203, while also providing a connecting component for the connection between the first elastic element 204 and the first latch 203. This eliminates the need for an additional connecting component on the first latch 203 to connect the first elastic element 204, simplifying the structure and reducing costs. For connecting the first elastic element 204, corresponding fixing buckles are provided in both the locking seat 201 and the operating arm 208.

[0124] Reference Figure 2 , Figure 4 , Figure 6 as well as Figures 15 to 18In some embodiments, both the first latch 203 and the second latch 206 are semi-cylindrical to allow them to be combined into a cylinder. The inner walls of one side of the first locking cavity 202 and the second locking cavity 205 are arc-shaped to match the first latch 203 and the second latch 206, respectively. The cross-section of the first locking cavity 202 is semi-circular following the first latch 203, and the cross-section of the second locking cavity 205 is semi-circular following the second latch 206. The first latch 203 and the second latch 206 fill the first locking cavity 202 and the second locking cavity 205, respectively. The first latch 203 can rotate by sliding against the wall in the first locking cavity 202, and the second latch 206 can rotate by sliding against the wall in the second locking cavity 205. The first latch 203 and the second latch 206 are mutually driven by rotation and engage with each other in their respective locking cavities. The first locking tongue 203 and the second locking tongue 206 have the same cross-sectional radius. When the first locking tongue 203 partially extends into the second locking cavity 205, it mates with the inner wall of the second locking cavity 205. Similarly, when the second locking tongue 206 partially extends into the first locking cavity 202, it mates with the inner wall of the first locking cavity 202. This structural design ensures a tighter fit between the locking tongue and the locking cavity. Even after the locking components drive each other and both extend into the other's locking cavity, they remain tightly fitted, preventing a decrease in fastening stability due to excessive assembly gaps.

[0125] Reference Figure 3 , Figure 16 and Figure 18In some embodiments, the locking seat 201 is provided with a first mounting groove 209, which makes the locking seat 201 hollow, reducing structural weight. The opening of the first mounting groove 209 is located on one side of the locking seat 201, for inserting the first latch 203 and the first elastic member 204 into the locking seat 201. A first partition 210 is provided inside the first mounting groove 209, which divides the internal space of the first mounting groove 209 into a first mounting cavity 211 and a first locking cavity 202. The first latch 203 is rotatably mounted in the first locking cavity 202, and the first elastic member 204 is located in the first mounting cavity 211. A through slot 212 is provided on the first partition plate 210, allowing the first elastic element 204 to extend into the first locking cavity 202 and connect with the first locking tongue 203 through the through slot 212; alternatively, when the first locking tongue 203 is connected to an operating arm 208, the operating arm 208 passes through the through slot 212 into the first mounting cavity 211 and connects with the first elastic element 204. When the first locking tongue 203 is rotatably mounted and connected to the operating arm 208, the through slot 212, having a certain length, provides space for the operating arm 208 to swing as the first locking tongue 203 rotates. This structural design allows the first locking tongue 203 and the first elastic element 204 to be installed in their respective cavities, fully utilizing the internal space of the locking seat 201, resulting in a compact assembly structure.

[0126] Reference Figure 2 , Figures 4 to 5 as well as Figures 11 to 12 In some embodiments, the locking assembly 200 further includes a first cover 213. The first cover 213 is mounted on the locking seat 201, closing the opening of the first mounting groove 209 and encapsulating the first latch 203 and the first elastic element 204 within the locking seat 201. The first cover 213 is provided with a first post 2131, and the first latch 203 is provided with a first machining groove 2031. The first post 2131 is inserted into the first machining groove 2031 so that the first latch 203 rotates around the first post 2131. This structural design enables the cover structure to not only encapsulate the first locking tongue 203 and the first elastic element 204, but also to achieve the rotational installation of the first locking tongue 203. Under the radial limitation of the first column 2131, the first locking tongue 203 will not completely disengage from the first locking cavity 202, ensuring the stability of rotational installation. Compared with machining the rotating shaft structure in the first mounting groove 209, it is easier to machine the first column 2131 on the first cover 213, reducing the difficulty of manufacturing.

[0127] Reference Figures 1 to 2 as well as Figures 8 to 10In some embodiments, the locking assembly 200 further includes an insert housing 214. The frame 1 is provided with a mounting hole 102, one end of which communicates with the locking hole 101, and the other end of which has an opening located on the side wall of the frame 1. A second locking cavity 205 is disposed in the insert housing 214, such that a second locking tongue 206 is installed in the insert housing 214. The insert housing 214 is installed in the mounting hole 102, and the opening of the second locking cavity 205 is aligned with the mounting hole 102. This structural design allows the second locking cavity 205 to be machined separately outside the frame 1 along with the insert housing 214, and the second locking tongue 206 can also be installed outside the frame 1 into the insert housing 214, making machining and assembly more convenient and improving production efficiency.

[0128] In some embodiments, the insert housing 214 is provided with a second mounting groove 215, which makes the insert housing 214 hollow, reducing structural weight. The opening of the second mounting groove 215 is located on one side of the insert housing 214, for inserting the second locking tongue 206 and the second elastic member 207 into the insert housing 214. A second partition 216 is provided inside the second mounting groove 215, which divides the internal space of the second mounting groove 215 into a second mounting cavity 217 and a second locking cavity 205. The second locking tongue 206 is rotatably mounted in the second locking cavity 205, and the first elastic member 204 is located in the first mounting cavity 217. The second partition 216 has a through slot 212, allowing the second elastic element 207 to extend into the second locking cavity 205 and connect with the second latch 206; alternatively, the second latch 206 is connected to a fastening arm 218, which passes through the through slot 212 into the second mounting cavity 217 and connects with the second elastic element 207. When the second latch 206 is rotatably mounted and connected to the fastening arm 218, the through slot 212, having a certain length, provides space for the fastening arm 218 to swing as the second latch 206 rotates. This structural design allows the second latch 206 and the second elastic element 207 to be installed in their respective cavities, fully utilizing the internal space of the insert box 214, resulting in a compact assembly structure.

[0129] Reference Figure 2 as well as Figures 13 to 14In some embodiments, the locking assembly 200 further includes a second cover 219. The second cover 219 is mounted on the insert housing 214, closing the opening of the second mounting groove 215 and encapsulating the second latch 206 and the second elastic member 207 within the insert housing 214. The second cover 219 is provided with a second post 2191, and the second latch 206 is provided with a second machining groove 2061. The second post 2191 is inserted into the second machining groove 2061 so that the second latch 206 rotates around the second post 2191. This structural design enables the cover structure to not only encapsulate the second locking tongue 206 and the second elastic element 207, but also to achieve the rotational installation of the second locking tongue 206. Under the radial limitation of the second column 2191, the second locking tongue 206 will not completely disengage from the second locking cavity 205, ensuring the stability of rotational installation. Compared with machining the rotating shaft structure in the second mounting groove 215, it is easier to machine the second column 2191 on the second cover 219, reducing the difficulty of manufacturing.

[0130] Furthermore, both the first locking tongue 203 and the second locking tongue 206 are semi-cylindrical. When they are fitted together, they form a cylinder. The locking assembly 200 includes a first cover 213 and a second cover 219. The first column 2131 of the first cover 213 and the second column 2191 of the second cover 219 are both semi-cylindrical. The first locking cavity 202 is aligned with the second locking cavity 205. The first locking tongue 203 and the second locking tongue 206 are fitted together, and the first column 2131 and the second column 2191 are fitted together, so that the first column 2131 and the second column 2191 are combined into a cylindrical pivot, filling the cylindrical space enclosed by the first processing groove 2031 and the second processing groove 2061. This structural design makes the first column 2131 and the second column 2191 compactly combined, and the first locking tongue 203 and the second locking tongue 206 remain stable when rotating.

[0131] Furthermore, referring to all the accompanying drawings, this application also provides a suspension locking structure, which includes a suspension frame 100 connected to the powertrain 2. In a vehicle, the suspension frame 100 is a component located within the vehicle's engine compartment. On one hand, the suspension frame 100, as part of the suspension assembly, provides fixation and support for the powertrain 2. On the other hand, the suspension frame 100 provides a mounting and fixing position for elastic components, enabling effective absorption and isolation of vibrations from the powertrain 2 by the elastic components.

[0132] In some embodiments, the suspension locking structure further includes a locking component 200, a portion of which is disposed on the suspension frame 100 and another portion of which is disposed on the vehicle frame 1. The locking component 200 securely connects the suspension frame 100 to the vehicle frame 1, thereby enabling the powertrain 2 to be stably mounted on the vehicle frame 1 via the suspension frame 100.

[0133] In some embodiments, the locking assembly 200 includes a locking seat 201. The locking seat 201 is disposed at one end of the suspension frame 100 near the frame 1. The frame 1 has a locking hole 101, the opening of which is located on the side of the frame 1 near the suspension frame 100. The locking seat 201 connects the suspension frame 100 to the frame 1. During installation, the suspension frame 100 can be inserted into the locking hole 101 simply to position and connect it to the frame 1, facilitating assembly and improving production efficiency.

[0134] The end of the locking seat 201 near the locking hole 101 can be set as a tapered structure, so that the locking seat 201 can be inserted into the locking hole 101. The tapered structure can guide the locking seat 201 to align with the center of the locking hole 101, so that it can be smoothly inserted into the locking hole 101, improving the accuracy and convenience of positioning and installation.

[0135] The locking seat 201 is provided with a first locking cavity 202, which is a chamber inside the locking seat 201. The first locking cavity 202 has an opening, which is located on the side wall of the locking seat 201. Through the opening of the first locking cavity 202, the component installed in the first locking cavity 202 can extend out of the first locking cavity 202 to the outside of the locking seat 201 or retract into the first locking cavity 202.

[0136] In another embodiment, the locking seat 201 can also be disposed on the frame 1, and the locking hole 101 is formed on the suspension frame 100. The locking seat 201 is inserted into the locking hole 101 of the suspension frame 100, thereby fixing the frame 1 to the suspension frame 100 by plugging it in. This design changes the plugging connection relationship between the suspension frame 100 and the frame 1, making manufacturing and assembly more flexible.

[0137] In some embodiments, the locking assembly 200 further includes a first locking tongue 203, which is disposed in a first locking cavity 202. The first locking tongue 203 extends out of the first locking cavity 202 to the locking seat 201 or retracts into the first locking cavity 202 through the opening of the first locking cavity 202.

[0138] In some embodiments, the locking assembly 200 further includes a second locking tongue 206 disposed within the locking hole 101 of the frame 1. The frame 1 has a second locking cavity 205, which is a chamber inside the frame 1. The second locking cavity 205 has an opening on the inner wall of the locking hole 101. The second locking tongue 206 extends from the second locking cavity 205 into the locking hole 101 or retracts into the second locking cavity 205 through the opening of the second locking cavity 205.

[0139] refer to Figures 19 to 22 In some embodiments, the locking assembly 200 further includes a first elastic element 204 disposed within the second locking cavity. The first elastic element 204 is connected to the second latch 206, and the elastic force generated by the first elastic element 204 drives the second latch 206 to move in a direction extending out of the second locking cavity 205, thereby allowing the second latch 206 to extend into the locking hole 101. An elastic element is a component capable of elastic deformation under external force and returning to its original shape after the external force is removed. Elastic elements may include, but are not limited to, springs, rubber, elastic plastics, elastic metal sheets, etc.

[0140] Reference Figures 19 to 22 The locking seat 201 is inserted into the locking hole 101. Constrained by the inner wall of the locking hole 101, the first locking tongue 203 is entirely located in the first locking cavity 202. The first locking cavity 202 is aligned with the second locking cavity 205, so that the opening of the first locking cavity 202 is aligned with the opening of the second locking cavity 205. The first elastic element 204 drives the second locking tongue 206 to extend through the opening of the second locking cavity 205 into the locking hole 101. The second latch 206 extends further into the first locking cavity 202 through the opening, thereby engaging with the locking seat 201 and preventing the locking seat 201 from disengaging from the locking hole 101. Simultaneously, the portion of the second latch 206 extending into the first locking cavity 202 pushes one side of the first latch 203, causing the other side of the first latch 203 to extend out of the first locking cavity 202 and into the second locking cavity 205, whereby the first latch 203 engages with the frame 1. This structural design allows the frame 1 and the locking seat 201 to engage with each other, increasing the number of fastening components to two. This not only improves the stability of the fastening but also reduces the stress on each fastening component, delaying or even preventing metal fatigue. This structural design also makes the second latch 206 an active component, with the first latch 203 and the second latch 206 working in tandem, facilitating assembly and improving production efficiency.

[0141] Before the locking seat 201 is inserted into the locking hole 101, ensure that the side of the first latch 203 furthest from the opening of the locking hole 101 is located inside the first locking cavity 202, so that the locking seat 201 can be inserted into the locking hole 101 without being obstructed by the protruding first latch 203. Furthermore, when the locking seat 201 is inserted into the locking hole 101, the opening of the locking hole 101 can push the side of the first latch 203 closest to the opening of the locking hole 101 into the first locking cavity 202, and under the constraint of the inner wall of the locking hole 101, ensure that the first latch 203 is completely located within the first locking cavity 202.

[0142] Furthermore, the first locking tongue 203 is connected to an operating arm 208, which extends beyond the locking seat 201. During maintenance and disassembly, an extension sleeve is inserted into the engine compartment and fitted onto the extended end of the operating arm 208. By moving the extension sleeve, the operating arm 208 moves accordingly, driving the first locking tongue 203 to retract completely into the first locking hole 101. Simultaneously, the first locking hole 101 drives the second locking tongue 206, which is in contact with it, so that the second locking tongue 206 overcomes the elastic force generated by the first elastic element 204, and the second locking tongue 206 retracts completely into the second locking hole 101, eliminating the jamming between the first locking tongue 203 and the second locking tongue 206. The locking seat 201 is then pulled out of the locking hole 101, and the suspension frame 100 is removed from the frame 1.

[0143] Reference Figure 23 In addition, this application also provides a vehicle including a frame 1 and a powertrain 2. The frame 1 has a locking hole 101, and the powertrain 2 is mounted on the suspension frame 100 of the suspension locking structure. The suspension locking structure is mounted on the frame 1, so that the powertrain 2 is fastened to the frame 1 by the suspension locking mechanism.

[0144] In some embodiments, a suspension bushing 300 is mounted on the suspension frame 100, and the powertrain 2 is connected to the suspension bushing 300, so that the powertrain 2 is mounted to the suspension frame 100 through the suspension bushing 300. The suspension bushing 300 is an elastic element, which is a component that can elastically deform under the action of external force and return to its original shape after the external force is removed, used to isolate vibration. The elastic element may include, but is not limited to, rubber, elastic plastic, elastic metal sheet, spring, etc. This structural design allows the vibration generated when the powertrain 2 is working to be partially buffered by the suspension bushing 300, reducing the vibration transmitted to the frame 1 and improving the comfort of the vehicle.

[0145] Furthermore, the powertrain 2 housing is equipped with a support leg 400, and the suspension bushing 300 is cylindrical. The suspension frame 100 has a connection hole 500. The suspension bushing 300 is installed into and mates with the connection hole 500. The suspension bushing 300 is fitted onto the support leg 400, thus connecting to the powertrain 2. This structural design allows the suspension bushing 300 to connect to the powertrain 2 360 degrees, eliminating vibrations generated by the powertrain 2 in all directions, improving vibration damping, and enhancing vehicle comfort.

[0146] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
