Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to an active suspension system and vehicle. Background Technology

Active suspension includes a linear motor, one end of which is connected to the vehicle body and the other end to the wheel via a wishbone. The motor can drive linear motion to adjust the vehicle height according to road conditions and driving status. In related technologies, the linear motor is located above the wishbone, which limits design flexibility. If space above the wishbone is limited, a customized design of the linear motor is required, increasing costs. Utility Model Content

[0047] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0048] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0049] In the description of this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0050] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0051] In the description of this utility model, the terms "one embodiment," "some embodiments," "illustrative embodiment," "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. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0052] As mentioned earlier, in related rotary suspension systems, the linear motor is connected to the tire via a fork arm, and is located above the fork arm. This design flexibility is low. If the space above the fork arm is limited, the linear motor needs to be customized, for example, by designing a shorter linear motor. Furthermore, different vehicle models have different spaces above the fork arm, thus requiring the design of various types of linear motors, all of which increase vehicle costs. Based on the above, this utility model proposes an active suspension system that can adjust the installation position of the linear drive component, reducing or eliminating the cost of customized design for the linear drive component. The following will describe this in conjunction with specific embodiments.

[0053] To facilitate understanding, the directions mentioned below will be explained first. In the vehicle coordinate system where the active suspension system 10 is installed behind the vehicle, the first direction is approximately the Z-axis direction of the vehicle, which is the height direction, and the second direction is approximately the Y-axis direction of the vehicle, which is the left and right direction.

[0054] Reference Figures 1 to 3The active suspension system 10 includes a connecting component 100 and a linear drive component 200. The connecting component 100 is used to connect to the vehicle's tire assembly, and the linear drive component 200 is used to connect to the vehicle's body. The linear drive component 200 can drive the connecting component 100 to move linearly in a first direction. It should be noted that when the active suspension system 10 is installed in the vehicle, the connecting component 100 is connected to the tire assembly. It can be considered that the connecting component 100 and the tire assembly are stationary relative to the ground in the height direction. Therefore, the drive of the linear drive component 200 on the connecting component 100 is specifically manifested as the raising and lowering of the linear drive component 200 and the vehicle body. In this way, the relative height between the wheels and the vehicle body can be actively adjusted according to road conditions and driving needs. For example, when there is a depression in the road surface that causes the wheels to move downward, the linear drive component 200 can drive the vehicle body to move upward. When there is a bump in the road surface that causes the wheels to move upward, the linear drive component 200 can drive the connecting component 100 and the tire assembly to move downward, thereby reducing bumps.

[0055] The connection assembly 100 includes a first connection portion 111 for connecting to a tire assembly of a vehicle, exemplarily referred to in [reference]. Figure 4 The first connecting part 111 is configured to extend generally along the first direction and has a mounting hole 111a for the drive shaft connecting the tire to pass through.

[0056] The linear drive assembly 200 includes a main body 210 and a power output part 220. The power output part 220 is connected to the main body 210 and is capable of linearly moving relative to the main body 210 in a first direction. For example, the linear drive assembly 200 is configured as a linear motor. The main body 210 includes a motor housing and windings and other mechanisms disposed in the motor housing. The power output part 220 is configured as the drive shaft of the linear motor. In other specific embodiments, the power output part 220 includes a combination of the drive shaft of the linear motor and other accessories, such as a drive shaft and a damper connected to the drive shaft.

[0057] In this embodiment, the linear drive assembly 200 is offset from the first connecting portion 111 in the second direction. The offset distance can be selected according to the situation of different vehicles. Taking the front compartment of the vehicle as an example, when there is not enough space directly above the first connecting portion 111, but there is space in other nearby positions, the linear drive assembly 200 can be offset to make full use of the space. The linear drive assembly 200 is connected to the tire assembly through the connecting assembly 100. In this way, on the one hand, the space inside the compartment can be made more fully, and on the other hand, the customized design cost of the linear drive assembly can be reduced or eliminated, so that the same type of linear drive assembly can be used in more vehicle models, thereby reducing costs.

[0058] It should be noted that the connecting component 100 may also be provided with connecting parts for connecting other vehicle components (such as brake components). In this embodiment, it is only necessary to cause an offset between the linear drive component 200 and the first connecting part 111, and the positional relationship between the linear drive component 200 and other connecting parts of the connecting component 100 is not limited. It should also be noted that a more specific understanding of the offset between two components or connecting parts involved in this utility model is: there is an offset between the center lines of the two components or connecting parts. For components or connecting parts with regular shapes and configured as bodies of revolution, the center line is its axis of rotation. For components or connecting parts with irregular shapes, their center lines can be determined by: determining the two farthest ends of the component or connecting part in the second direction, establishing a line connecting the two farthest ends, and the center line passing through the midpoint of this line. For example, Figure 1 The center line between the linear drive assembly 200 and the first connecting part 111 is roughly indicated by two dotted lines.

[0059] Based on the first embodiment, in some embodiments of this utility model, the active suspension system 10 includes various types of connecting components 100, wherein the deviation distance between the linear drive component 200 and the first connecting part 111 is different for different types of connecting components 100. It is understood that for different vehicle models, the interior size and component layout are different, therefore the location of available space also varies. This embodiment, by providing multiple connecting components 100, allows for adaptive installation according to different vehicle models, thereby adjusting the installation position of the linear drive component 200.

[0060] It should be noted that when interpreting the offset between the linear drive assembly 200 and the first connecting part 111 using the aforementioned centerline, their centerlines may be parallel or non-parallel. For the former, the offset between the linear drive assembly 200 and the first connecting part 111 is the distance between their centerlines in the second direction. For the latter, since the distance between the centerlines is not a constant value, the offset can be determined in the following way: Determine a measuring plane parallel to the horizontal plane, install the linear drive assembly 200 onto the same or similar type of vehicle or test fixture through different connecting assemblies 100, fix the relative height between the measuring plane and the vehicle or fixture, and then measure the distance between the intersection point of the centerline of the linear drive assembly 200 and the first connecting part 111 and the measuring plane in different connection situations. This distance is the offset between the linear drive assembly 200 and the first connecting part 111.

[0061] When the active suspension system 10 includes multiple types of connection components 100, in some embodiments of the present invention, refer to Figure 2The connecting assembly 100 includes a first bracket 110 and a second bracket 120. The first bracket 110 has a first connecting portion 111 and a second connecting portion 112, and the second bracket 120 has a third connecting portion 121a and a fourth connecting portion 122a. The second bracket 120 can be an integral structure or a separate structure. The second bracket 120 is detachably connected to the linear drive assembly 200 through the third connecting portion 121a, and the first bracket 110 and the second bracket 120 are detachably connected through the second connecting portion 112 and the fourth connecting portion 122a. Thus, the second bracket 120 can be separated from the linear drive assembly 200 and the first bracket 110, that is, the second bracket 120 can be replaced. For example, the third connecting portion 121a can be connected to the linear drive assembly 200 by means of fastener connection, clamping fixation, snap-fit ​​fixation, etc., and the second connecting portion 112 and the fourth connecting portion 122a can be connected by means of fastener connection, clamping fixation, snap-fit ​​fixation, etc.

[0062] In this embodiment, the third connecting portion 121a of the second bracket 120 is offset from the fourth connecting portion 122a in the second direction. Moreover, the offset distance between the third connecting portion 121a and the fourth connecting portion 122a is not equal for different types of connecting components 100. Thus, by replacing different second brackets 120, the linear drive component 200 can be offset by different distances relative to the first connecting portion 111. Furthermore, the same first bracket 110 can be selected for different vehicle models. Since the first bracket 110 is used to connect with the tire assembly, its modification needs to be verified and the replacement cost is high. Therefore, by replacing the second bracket 120 and retaining the first bracket 110, the cost can be further reduced.

[0063] It should be noted that in this embodiment, the first connecting part 111 and the second connecting part 112 may be offset or not offset in the second direction. When the first connecting part 111 and the second connecting part 112 are not offset, the offset between the third connecting part 121a and the fourth connecting part 122a is larger. When the first connecting part 111 and the second connecting part 112 are offset, the offset between the third connecting part 121a and the fourth connecting part 122a is smaller.

[0064] It is understood that in other embodiments, the first support 110 may be retained and the second support 120 may be replaced with one with a different offset distance.

[0065] When the connecting assembly 100 includes a first bracket 110 and a second bracket 120, in some embodiments of the present invention, refer to Figure 2The second support 120 is configured as a split structure, comprising a first sub-component 121 and a second sub-component 122. The first sub-component 121 has a fifth connecting portion 121b and the aforementioned third connecting portion 121a, while the second sub-component 122 has a sixth connecting portion 122b and the aforementioned fourth connecting portion 122a. The second support 120 is connected to the linear drive assembly 200 via the first sub-component 121 and to the first support 110 via the second sub-component 122. The first sub-component 121 and the second sub-component 122 are detachably connected via the fifth connecting portion 121b and the sixth connecting portion 122b. Thus, the first sub-component 121 can be separated from the linear drive assembly 200 and the second sub-component 122, meaning that the first sub-component 121 can be replaced.

[0066] In this embodiment, the third connecting portion 121a of the first sub-component 121 is offset from the fifth connecting portion 121b in the second direction. Furthermore, the offset distance between the third connecting portion 121a and the fifth connecting portion 121b varies for different types of connecting assemblies 100. Thus, by replacing different first sub-components 121, the linear drive assembly 200 can be offset relative to the first connecting portion 111 by different distances. In addition, by further disassembling the first bracket 110, the more complex part can be retained for multi-model compatibility, while the simpler part can be replaced, thereby further reducing costs.

[0067] It should be noted that the third connecting part 121a of the first sub-component 121 has the same structure for different types of connecting components 100, so it can be adapted to the same type of linear drive component 200 without changing the connecting structure on the linear drive component 200.

[0068] When the second bracket 120 includes a first sub-component 121 and a second sub-component 122, in some embodiments of the present invention, refer to Figure 4 and Figure 6In this design, one of the second connecting part 112 and the fourth connecting part 122a is configured as a connecting post, and the other as a clamping sleeve. The connecting post is inserted into the clamping sleeve and fixed by the clamping sleeve. In this way, the second sub-component 122 and the first bracket 110 can be connected and separated by a simple operation, thereby improving ease of use. For example, the second connecting part 112 is configured as a clamping sleeve, which specifically includes a cylindrical body. The side wall of the cylindrical body has a groove that runs through it along its own axis. The outer circumferential surface of the cylindrical body has fixing protrusions on both sides of the groove. The fixing protrusions have connecting holes for fasteners to pass through. Before locking, the fastener is in an unlocked state, and the inner diameter of the cylindrical body is slightly larger than or equal to the outer diameter of the connecting post. The connecting post can be inserted into the interior of the cylindrical body. Then, the fastener is locked. During the locking process, the fastener drives the fixing protrusions on both sides to move closer together, thereby reducing the inner diameter of the cylindrical body, so that the inner side wall of the cylindrical body clamps the connecting post to achieve fixation.

[0069] Based on this, in some specific embodiments, the sixth connecting part 122b of the second sub-component 122 is configured as a flange coaxial with the connecting post or the jacket, and the flange is provided with a plurality of connecting holes distributed circumferentially. In this case, the second sub-component 122 as a whole constitutes a rotating body, and the center line between the fourth connecting part 122a and the sixth connecting part 122b is the rotation axis of the second sub-component 122.

[0070] When the second bracket 120 includes a first sub-component 121 and a second sub-component 122, in some embodiments of the present invention, refer to Figure 5 The first sub-component 121 is configured as a flat plate structure. For example, the first sub-component 121 includes two plate layers. The lower plate layer serves as the third connecting part 121a, which is constructed as a rotating body. A portion of the upper plate layer serves as the fifth connecting part 121b. The extent of the fifth connecting part 121b is roughly indicated by dashed lines in the figure. The fifth connecting part 121b has multiple circumferentially distributed connecting holes. The connecting holes on the fifth connecting part 121b correspond to the connecting holes on the sixth connecting part 122b, allowing for connection via fasteners. Furthermore, to clearly illustrate the offset between the third connecting part 121a and the fifth connecting part 121b in the second direction... Figure 5 The center line between the two is indicated by a dashed line.

[0071] When the active suspension system 10 includes multiple types of connecting components 100, in some embodiments of the present invention, the connecting component 100 further includes multiple third connecting portions 121a. The connecting component 100 is connected to the linear drive component 200 through one of the third connecting portions 121a. Each third connecting portion 121a is offset from the first connecting portion 111 along a second direction, and the offset distance between each third connecting portion 121a and the first connecting portion 111 is unequal. The difference between this embodiment and the previous embodiment is that the previous embodiment provides multiple types of connecting components 100, while this embodiment provides multiple third connecting portions 121a on the same connecting component 100, thereby reducing the types of connecting components 100.

[0072] In some specific embodiments, the connecting assembly 100 includes a first bracket 110 and a second bracket 120. The first bracket 110 has a first connecting portion 111 and a second connecting portion 112, and the second bracket 120 has a third connecting portion 121a and a fourth connecting portion 122a. The second bracket 120 is detachably connected to the linear drive assembly 200 through the third connecting portion 121a, and the first bracket 110 and the second bracket 120 are detachably connected to each other through the second connecting portion 112a and the fourth connecting portion 122a. Furthermore, the second bracket 120 has a plurality of third connecting portions 121a.

[0073] Based on the first embodiment, in some embodiments of this utility model, reference is made to Figures 1 to 3 The connecting component 100 includes a first bracket 110 and a second bracket 120. The first bracket 110 has a first connecting portion 111 and a second connecting portion 112, and the second bracket 120 has a third connecting portion 121a and a fourth connecting portion 122a. The first bracket 110 and the second bracket 120 are connected through the second connecting portion 112 and the fourth connecting portion 122a. The second bracket 120 is connected to the linear drive component 200 through the third connecting portion 121a. As mentioned above, since the first bracket 110 needs to be connected to the tire assembly, it may also need to be provided with other connecting portions for connecting brake components, CV joints, and other devices, making the overall structure relatively complex. In this embodiment, the connecting component 100 is set as a split structure, and is connected to the linear drive component 200 through the second bracket 120. The second bracket 120 is designed and manufactured separately, which can reduce the structural complexity of the first bracket 110.

[0074] Based on the first embodiment, in some embodiments of this utility model, reference is made to Figures 1 to 3 The linear drive assembly 200 includes a main body 210 and a power output part 220. The power output part 220 is connected to the main body 210 and can move linearly relative to the main body 210 in a first direction. The main body 210 and the power output part 220 can be understood with reference to the foregoing embodiments.

[0075] One of the main body 210 and the power output part 220 is used to connect to the vehicle body, and the other is connected to the connecting assembly 100. Based on this, the aforementioned "deviation of the linear drive assembly 200 from the first connecting part 111" specifically means that the centerline of the main body 210 and / or the centerline of the power output part 220 deviates from the first connecting part 111 in a second direction. For example, as... Figure 1 As shown, the power output unit 220 is connected to the vehicle body via the tower top 400, the main body 210 is connected to the connecting assembly 100, and the linear drive assembly 200 is connected to the vehicle body via the power output unit 220. The centerline of the power output unit 220 is deviated from the first connecting part 111 in the second direction.

[0076] Based on the first embodiment, in some embodiments of this utility model, the deviation of the linear drive component 200 and the first connecting portion 111 in the second direction specifically means that the projection of the linear drive component 200 in the first direction does not coincide with the projection of the first connecting portion 111 in the first direction. Specifically, it is recommended that the projections of the linear drive component 200 and the first connecting portion 111 on a projection plane perpendicular to the first direction are distributed along the second direction and have no overlapping area.

[0077] Based on the first embodiment, in some embodiments of this utility model, reference is made to Figure 1 The connecting assembly 100 includes a first bracket 110 and a second bracket 120. The first bracket 110 has a first connecting portion 111 and a second connecting portion 112, and the second bracket 120 has a third connecting portion 121a and a fourth connecting portion 122a. The second bracket 120 is connected to the linear drive assembly 200 through the third connecting portion 121a, and the first bracket 110 and the second bracket 120 are connected to each other through the second connecting portion 112 and the fourth connecting portion 122a. The first bracket 110 and the second bracket 120 can be understood with reference to the foregoing embodiments.

[0078] In this embodiment, the first connecting portion 111 is offset from the second connecting portion 112 in the second direction, and the first connecting portion 111 is located on the side of the second connecting portion 112 away from the linear drive assembly 200, so as to Figure 1 As shown in the example, the first connecting part 111 is located to the right of the second connecting part 112, and the linear drive assembly 200 is located to the left of the second connecting part 112. This arrangement helps to extend the offset between the linear drive assembly 200 and the first connecting part 111.

[0079] Based on the first embodiment, in some embodiments of this utility model, reference is made to Figure 1 , Figure 2The connecting component 100 includes a first bracket 110 and a second bracket 120. The first bracket 110 has a first connecting portion 111 and a second connecting portion 112. The second bracket 120 has a third connecting portion 121a and a fourth connecting portion 122a. The second bracket 120 is connected to the linear drive component 200 through the third connecting portion 121a. The first bracket 110 and the second bracket 120 are connected to each other through the second connecting portion 112 and the fourth connecting portion 122a. The first bracket 110 and the second bracket 120 can be understood with reference to the foregoing embodiments.

[0080] In this embodiment, the second connecting portion 112 and the fourth connecting portion 122a deviate from the center line of the linear drive assembly 200 in a second direction toward the first connecting portion 111. That is, the second connecting portion 112 and the fourth connecting portion 122a deviate from the center line of the linear drive assembly 200 toward one side of the first connecting portion 111. Figure 2 As shown in the example, the center lines of the second connecting part 112 and the fourth connecting part 122a are both located to the right of the center line of the linear drive assembly 200. This helps to ensure the offset between the linear drive assembly 200 and the first connecting part 111.

[0081] In other embodiments, the connecting component 100 further includes a third connecting portion 121a, through which the connecting component 100 is connected to the linear drive component 200. The connecting component 100 can be a split structure as described above, with the third connecting portion 121a disposed on the second bracket 120; alternatively, the connecting component 100 can be an integral structure. In this embodiment, the third connecting portion 121a deviates from the centerline of the power output portion 220 in a second direction toward the first connecting portion 111. For example, the third connecting portion 121a deviates from the centerline of the linear drive component 200 toward one side of the first connecting portion 111, thus helping to ensure the offset between the linear drive component 200 and the first connecting portion 111.

[0082] In the foregoing embodiments, since the second connecting portion 112 and the fourth connecting portion 122a deviate from the centerline of the linear drive assembly 200, or the third connecting portion 121a deviates from the centerline of the linear drive assembly 200, an imbalance of force may occur between the main body 210 and the power output portion 220 of the linear drive assembly 200, affecting its driving effect and lifespan. Figure 1As shown in the example, if the second connecting part 112 and the fourth connecting part 122a are offset to the right, the connecting assembly 100 as a whole applies force from the right side of the main body 210 of the linear drive assembly 200, causing the main body 210 to tend to deflect counterclockwise relative to the power output part 220. Based on this, in some embodiments, the active suspension system 10 improves this problem by applying asymmetrical force through the elastic element 300. Specifically, the linear drive assembly 200 includes a main body 210 and a power output part 220. The power output part 220 is connected to the main body 210 and can move linearly relative to the main body 210 in a first direction. The main body 210 and the power output part 220 can be understood with reference to the aforementioned embodiments. In the second direction, the linear drive assembly 200 has a first side located on the centerline of the power output part 220 facing the first connecting part 111, and a second side away from the first connecting part 111. Figure 1 As shown in the example, with the center line of the power output section 220 as the boundary, the right side of the linear drive assembly 200 is the first side, and the left side is the second side.

[0083] Furthermore, the active suspension system 10 also includes an elastic element 300. When the power output unit 220 moves relative to the main body 210, the elastic element 300 is configured to apply a force to the linear drive assembly 200, thereby achieving buffering and shock absorption. In this embodiment, the force applied by the elastic element 300 to the linear drive assembly 200 is opposite in direction to the force applied by the connecting assembly 100 to the linear drive assembly 200, and the force applied by the elastic element 300 on the first side is greater than the force applied on the second side, thereby balancing the force applied by the connecting assembly 100 as a whole to the linear drive assembly 200. Figure 1 As shown in the example, when the connecting component 100 applies force from the lower right side of the linear drive component 200, the elastic element 300 applies force downward, and the force applied by the elastic element 300 on the right side is greater than the force applied on the left side.

[0084] When the active suspension system 10 also includes an elastic element 300, in some embodiments of this utility model, refer to Figure 1 The power output unit 220 is used to connect to the vehicle body, the main body 210 is connected to the connecting assembly 100, and the elastic element 300 is configured as a spring sleeved on the power output unit 220, with one end of the spring abutting against the main body 210 and the other end abutting against the top 400. In this embodiment, the spring bends or folds towards the first connecting part 111 to achieve asymmetrical force application. It should be noted that when describing the spring as bending towards the first connecting part 111, it means that the spring as a whole is arc-shaped, for example, C-shaped, and the open side of the C-shape faces away from the first connecting part 111. When describing the spring as folding towards the first connecting part 111, it means that the spring includes at least two segments, which are intersecting and relatively inclined to form an included angle.

[0085] A second aspect of this utility model also proposes a vehicle, which includes a tire assembly and the active suspension system 10 described in the foregoing embodiments, with the tire assembly connected to a first connecting portion 111. The vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. It can also be a commercial vehicle, such as a van, bus, small truck, or large trailer. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0086] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
