Detailed implementation manners

[0030] To make the above objects, features, and advantages of the present application more obvious and understandable, the following will describe the detailed implementation manners of the present application with reference to the accompanying drawings. It can be understood that the specific embodiments described herein are only used to explain the present application, rather than limiting the present application. In addition, it should be noted that for the sake of description, only parts related to the present application are shown in the drawings, rather than all the structures. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0032] In the description of the present application, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of the described features. In the description of the present application, "a plurality of" means two or more, unless otherwise specifically defined.

[0033] In the description of the present application, it should be noted that unless otherwise clearly defined and limited, the terms "mounted", "connected", and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a connection that can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0034] Please refer jointly to Figure 1 and Figure 2 , Figure 1It is a schematic structural diagram of an embodiment of the strut assembly provided by this application. Figure 2 It is Figure 1 a schematic disassembled structural diagram of the center strut assembly. In one aspect of this application, a strut assembly 100 is provided. The strut assembly 100 includes a first support 1, a second support 2, a connecting rod 4, a first elastic member 5, and a second elastic member 6. One end of the connecting rod 4 is fixedly connected to the first support 1, and the other end is movably connected to the second support 2. The first elastic member 5 is sleeved on the outer periphery of the connecting rod 4, and one end of the first elastic member 5 is detachably connected to the first support 1, and the other end is fixedly connected to the second support 2. The second elastic member 6 abuts between the first support 1 and the second support 2. Specifically, the telescopic direction of the first elastic member 5 is the same as that of the second elastic member 6. The strut assembly 100 of the embodiment of this application can be connected to the first support 1 through the first elastic member 5, so that the first elastic member 5 and the second elastic member 6 are in parallel, thereby improving the stiffness and the vehicle's handling performance. It is also possible to disconnect the connection between the first elastic member 5 and the first support 1 to reduce the stiffness and improve the vehicle's comfort. That is to say, the stiffness of the strut assembly 100 can be adjusted according to different vehicle usage conditions to achieve both comfort and handling performance and balance. Moreover, since the strut assembly 100 of the embodiment of this application can achieve stiffness adjustment only by adding a first elastic member 5, the cost of the strut assembly 100 is low, and the versatility is improved.

[0035] Combined with Figure 3 and Figure 4 as shown, Figure 3 it is Figure 1 a schematic structural diagram of the first elastic member in Figure 4 it is Figure 1 a schematic structural diagram of the second elastic member in

[0036] Combined with Figures 5 to 7 as shown, Figure 5 it is Figure 1 a schematic structural diagram of the first support in Figure 6 it is Figure 1 a schematic structural diagram of the assembled structure of the second support and the outer cylinder in Figure 7 it is Figure 1Schematic diagram of the structure of the middle connecting rod. Further, both the first support 1 and the second support 2 are provided with through holes 9 for the connecting rod 4 to pass through, and the first support 1 and the second support 2 are connected by the connecting rod 4. The first support 1 can be connected to the vehicle body, and the second support 2 can be connected to the steering knuckle or control arm on the wheel side of the vehicle. During the driving of the vehicle, vibrations will inevitably occur. The vibrations are transmitted to the second support 2, enabling the second support 2 to move relative to the connecting rod 4 towards or away from the first support 1, and then the second elastic member 6 is used for vibration damping. After the vibration damping, it is transmitted to the first support 1 and even the vehicle body, thereby improving comfort or handling performance. It should be noted that since the opposite ends of the second elastic member 6 respectively abut against the first support 1 and the second support 2, and the first elastic member 5 is fixedly connected to the second support 2, when the first elastic member 5 is connected to the first support 1, the second support 2 moves along the connecting rod 4 towards the first support 1, causing both the first elastic member 5 and the second elastic member 6 to be compressed towards the first support 1, that is, the first elastic member 5 and the second elastic member 6 are in parallel connection to increase the stiffness.

[0037] Please continue to combine Figure 1 and Figure 8 , Figure 8 is Figure 1 Schematic diagram of the structure of the third support in the middle. In an embodiment of the present application, the strut assembly 100 further includes a third support 3, and the third support 3 is detachably connected to the first support 1; a first mounting portion 31 is provided on the surface of the third support 3 facing the second support 2, and a second mounting portion 21 is provided on the surface of the second support 2 facing the third support 3. The opposite ends of the first elastic member 5 are respectively fixedly connected to the first mounting portion 31 and / or the second mounting portion 21.

[0038] Specifically, as Figure 9 shown, Figure 9 is Figure 1 Schematic diagram of the assembly structure of the first support, the third support and the first elastic member in the middle. In one embodiment, the third support 3 is located between the first support 1 and the second support 2 and is coaxially arranged with the first support 1 and the second support 2. Combining Figure 6 and Figure 8 shown, the first mounting portion 31 and the second mounting portion 21 can be arc-shaped grooves to facilitate the embedding and installation of the first elastic member 5 and improve stability. The first elastic member 5 is fixedly connected to the third support 3 and the second support 2, and then is connected or disconnected from the first support 1 through the third support 3 to achieve an increase or decrease in stiffness. As Figure 8As shown, the third support 3 can be an annular support with a hollow center, and a through hole 9 for the connecting rod 4 to pass through is provided at its center. That is to say, the connecting rod 4 can also play a role in installing and supporting the third support 3. In another embodiment, the strut assembly 100 can also include a fourth support, which is located between the third support 3 and the second support 2. The opposite ends of the first elastic member 5 are respectively connected to the third support 3 and / or the fourth support. The fourth support can be integrated on the second support 2 to simplify the structure and reduce costs. The fourth support can also be provided separately. When the first support 1 is disconnected from the third support 3, the fourth support can also be disconnected from the second support 2, so as to improve or avoid the influence of the first elastic member 5 on the damping effect of the second elastic member 6. When the first support 1 is connected to the third support 3, the fourth support can also be connected to the second support 2 to improve the stiffness of the strut assembly 100.

[0039] Furthermore, since there are more solutions for the connection method between the first support 1 and the third support 3, such as connection by elastic buckles, electronic switches, etc., the detachable connection between the first support 1 and the third support 3 can improve the controllability and stability of stiffness adjustment.

[0040] Please continue to refer to Figures 9 to 11 , Figure 10 which is Figure 1 a schematic structural view of the assembly structure of the first support and the control switch in Figure 11 and Figure 1 is a schematic structural view of the assembly structure of the third support and the control switch in . In an embodiment of the present application, the first support 1 is provided with an extension arm 11 extending towards the second support 2, and a plurality of locking holes 12 are provided on the extension arm 11; the third support 3 is provided with a third mounting portion 32; the strut assembly 100 further includes a control switch 7, one end of the control switch 7 is mounted on the third mounting portion 32, and the other end is detachably mounted in the locking hole 12.

[0041] Specifically, the third support 3 and the connecting rod 4 can be movably connected, so that after the control switch 7 is disengaged from the locking hole 12, the third support 3 can move along the connecting rod 4 and when it needs to be locked, the control switch 7 can be aligned with the locking hole 12. In one embodiment, the third mounting portion 32 can be provided on the outer peripheral surface of the third support 3 and corresponds to the extension arm 11. Since the first elastic member 5 is fixedly connected to the third support 3, when the third support 3 moves along the connecting rod 4, circumferential rotation can be reduced or avoided so that the third mounting portion 32 and the extension arm 11 are misaligned.

[0042] Furthermore, in order to improve stability, a limiting member (not shown in the figure) can be provided on the third support 3 to limit the circumferential rotation of the third support 3.

[0043] Please continue to refer to Figure 12 , Figure 12Yes Figure 1 It is a schematic structural diagram of the control switch. In an embodiment of the present application, the control switch 7 includes a control part 71 and a locking head part 72. The control part 71 is installed on the third installation part 32. The control part 71 is connected to the locking head part 72, and the control part 71 can control the locking head part 72 to perform telescopic movement. Specifically, the third installation part 32 is aligned with the lock hole 12. When the locking head part 72 extends out and is installed in the lock hole 12, the third support 3 is connected to the first support 1; when the locking head part 72 retracts and disengages from the lock hole 12, the third support 3 is separated from the first support 1.

[0044] Through the above structure, there are a locked state and an unlocked state between the first support 1 and the third support 3. In the locked state, the locking head part 72 extends out from the control switch 7 and is installed in the lock hole 12, so that the third support 3 is fixedly connected to the first support 1, and further the first elastic member 5 and the second elastic member 6 are connected in parallel, thereby improving the stiffness and enhancing the vehicle's handling performance. In the unlocked state, the locking head part 72 disengages from the lock hole 12, so that the third support 3 is separated from the first support 1. The third support 3 can move along the connecting rod 4, and the connection relationship between the first elastic member 5 and the second elastic member 6 is disconnected. After losing the stiffness improvement effect of the first elastic member 5, due to the smaller stiffness of the second elastic member 6, the vehicle's comfort is improved.

[0045] Furthermore, the locking head part 72 can include a telescopic rod 721, and is connected to the control part 71 through the telescopic rod 721. In a specific embodiment, the control part 71 is fixed to the third installation part 32, and can control the telescopic rod 721 to move relative to the control part 71 to achieve the telescopic movement of the locking head part 72. Of course, in another specific embodiment, the control part 71 can also be connected to the telescopic rod 721 and fixed to the third installation part 32 to control the locking head part 72 to move relative to the telescopic rod 721. In other specific embodiments, the locking head part 72 can also be installed or disassembled in the lock hole 12 by other means, which will not be elaborated here.

[0046] In an embodiment of the present application, the sizes of a plurality of lock holes 12 are equal and are arranged at equal intervals along the extension arm 11, which can divide the stiffness into several gears to facilitate the adjustment of the stiffness and improve the accuracy of the control.

[0047] Specifically, a plurality of lock holes 12 are provided on the extension arm 11. In addition to facilitating the locking of the locking head part 72, the stiffness can also be adjusted to different gears by inserting the locking head part 72 into different lock holes 12. That is to say, the stiffness in the locked state can be further adjusted according to different vehicle usage conditions. For example, if ten lock holes 12 are equally distributed, then in the direction from the second support 2 to the first support 1, the stiffness corresponding to the ten lock holes 12 can be in 1-10 gears from large to small, further enhancing the vehicle's handling performance.

[0048] Further, a detection device (not shown in the figure) may be provided on the extension arm 11 for detecting whether the third support 3 reaches a specified stiffness gear. A driving device may also be provided on the third support 3, and the driving device may be electrically connected to the vehicle body in the same way as the control switch 7, so as to facilitate locking the third support 3 in the gear corresponding to the stiffness.

[0049] In an embodiment of the present application, as Figure 8 shown, the third mounting portion 32 is located on the outer peripheral surface of the third support and communicates with the inner peripheral surface, so as to simplify the process, improve production efficiency and reduce costs.

[0050] Specifically, the third mounting portion 32 may be a mounting hole. That is to say, when producing the third support 3, only a mounting hole penetrating the inner peripheral surface and the outer peripheral surface needs to be drilled along the radial direction, which simplifies the construction process and reduces the design cost.

[0051] In an embodiment of the present application, as Figure 5 and Figure 9 shown, the two extension arms 11 are arranged relatively spaced apart, and the locking holes 12 on one extension arm 11 correspond to the locking holes 12 on the other extension arm 11 one by one.

[0052] Specifically, by locking the two locking holes 12 on both sides of the third support 3, the connection between the third support 3 and the first support 1 is made more stable, improving the stability.

[0053] Further, when the third support 3 is disconnected from the first support 1, the third support 3 can also slide along the extension arms 11 on both sides, that is, the third support 3 is limited by the first elastic member 5, the connecting rod 4 and the extension arms 11, improving the stability. In a specific embodiment, the connection line of the two extension arms 11 may pass through the center of the circle of the first support 1, and the extension arms 11 may extend to connect to the second support 2. In another specific embodiment, in order to simplify the structure and save materials, there may also be a gap between the extension arms 11 and the second support 2, and the length of the extension arms 11 may be greater than or equal to the distance between the third support 3 and the first support 1 when the first elastic member 5 is compressed toward the second support 2, so that the third support 3 can be locked in all gears.

[0054] In an embodiment of the present application, the aperture and depth of the locking hole 12 are both greater than or equal to the size of the locking head 72, so as to facilitate the telescopic movement of the locking head 72 in the locking hole 12.

[0055] In an embodiment of the present application, as Figure 1 and Figure 6 shown, the second elastic member 6 is coaxially sleeved on the outer periphery of the first elastic member 5; the strut assembly 100 further includes an outer cylinder 8, and the outer cylinder 8 is connected to the side of the second support 2 facing away from the first support 1 to push the second support 2 to move toward or away from the first support 1.

[0056] Specifically, the outer cylinder 8 can be a structure such as an oil storage barrel or an oil storage cylinder to facilitate the movement of the second support 2. In addition, the outer cylinder 8 can also support structures such as the second support 2, the connecting rod 4, the second elastic member 6, and the first elastic member 5.

[0057] In a specific embodiment, one end of the connecting rod 4 can be rigidly connected to the vehicle body through the first support 1, and the other end passes through the second support 2 and extends into the inner part of the outer cylinder 8. The outer cylinder 8 can be connected to a steering knuckle or a control arm on the wheel side. During the driving of the vehicle, the wheel will inevitably bounce up and down. Under the drive of the wheel, the outer cylinder 8 moves reciprocally relative to the connecting rod 4, thereby driving the second support 2 to move towards or away from the first support 1, causing the second elastic member 6 to continuously switch between the compressed and released states to offset part of the vibration. When the first elastic member 5 and the second elastic member 6 are connected in parallel, the first elastic member 5 and the second elastic member 6 jointly bear the pressure brought by the second support 2, reducing the deformation amount of the second elastic member 6, improving the vibration transfer efficiency, and reducing the loss amount of vibration transfer. After the vibration is transmitted to the vehicle body, the driver, passengers, etc. can accurately grasp the magnitude of the vibration and precisely control the vehicle, thereby improving the handling performance of the vehicle. For example, on a flat highway, due to the increase in speed, it is necessary to accurately grasp the change in wheel vibration. Therefore, it can be controlled to make the first support 1 and the third support 3 enter the locked state, increasing the stiffness of the strut assembly 100 and reducing the loss amount of vibration transfer, thereby improving the handling performance of the vehicle. Further, according to the speed, road conditions, etc., the third support 3 can be controlled to be connected to the first support 1 at the corresponding stiffness gear to achieve the balance between handling and comfort.

[0058] Of course, in the case of uneven road surfaces, since the bouncing amplitude of the wheel is relatively large, the strut assembly 100 needs to reduce the vibration transmitted by it. At this time, it can be controlled to make the third support 3 and the first support 1 enter the unlocked state. Since the stiffness of the second elastic member 6 is relatively low, when the second support 2 moves towards the first support 1, the second elastic member 6 can deform by compression to offset part of the pressure, thereby reducing the amount of vibration transfer, making part or a small amount of vibration transmitted to the vehicle body, reducing the impact on the ride, and improving the comfort of the vehicle.

[0059] Furthermore, in another specific embodiment, an automatic system can also be designed to automatically control the locking and unlocking of the third support 3 by detecting the road conditions and the operating conditions of the vehicle, realizing the automation of stiffness adjustment, and further improving the balance between the overall handling and comfort of the vehicle.

[0060] On the other hand, the present application also provides a vehicle, which includes the above-mentioned strut assembly 100. Specifically, since the vehicle includes the strut assembly 100 described in the above embodiment, it also has the beneficial effects of the above-mentioned strut assembly 100, which will not be elaborated here.

[0061] It should be noted that terms such as "horizontal" and "vertical" do not require the components to be absolutely horizontal or vertical, but can be slightly inclined; terms such as "parallel" and "perpendicular" do not mean that the fittings are absolutely parallel or perpendicular to each other, but can have a certain angular deviation. For example, "horizontal" only means that its direction is more horizontal relative to "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined. In addition, the orientation or positional relationship indicated by terms such as "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc. is based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the products of the present application are usually placed during use. It is only for the convenience of describing the embodiments of the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation to the present application.

[0062] It can be understood that the meaning of "a plurality of" herein is at least two, such as two, three, etc., unless there are specific restrictive descriptions. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products or devices. The term "and / or" merely describes the association relationship of associated objects and indicates that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " herein generally represents an "or" relationship between the associated objects before and after.

[0063] The above are only the embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made by using the content of the specification and drawings of the present application, or directly or indirectly applied in other related technical fields, shall be equally included in the patent protection scope of the present application.
