Description

Technical Field

[0001] This utility model relates to the field of vehicle engineering technology, and specifically to an automobile and an independent suspension structure. Background Technology

[0002] Independent suspension in automobiles is a suspension system in which each wheel is connected to the vehicle frame via its own independent suspension bracket. The structure of an independent suspension typically includes suspension brackets, shock absorbers, guiding mechanisms, and elastic elements, such as coil springs, torsion bar springs, or air springs, which support the vehicle's weight and absorb road impacts. Taking torsion bar springs as an example, when a car is driving on uneven roads, during cornering, or under overload conditions, the torsion bar springs in the independent suspension will undergo lateral deformation. With continued driving, the torsion bar springs will experience metal fatigue, leading to spring slack and excessive lateral deformation. Existing technologies cannot provide timely warnings when torsion bar spring slack occurs; the problem is only discovered during quality inspection or maintenance, resulting in a lag in risk management and increased driving risks.

[0003] In view of this, a new automotive and independent suspension structure is proposed to solve the problem of lag in the warning of torsion bar spring relaxation in the prior art. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing an automobile and an independent suspension structure.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0006] An independent suspension structure includes a suspension bracket and a torsion bar spring, the independent suspension structure further comprising:

[0007] Support block, the support block being mounted on the suspension bracket;

[0008] The outer casing is mounted on the outside of the support block, and the torsion bar spring is sleeved inside the outer casing;

[0009] A detection structure is installed inside the housing;

[0010] The detection structure includes an alarm, a touch switch connected in series in the alarm switch circuit, and a movable plate; the movable plate and the touch switch have a preset initial distance, and the movable plate is radially movably mounted on the housing so that the movable plate can move towards or away from the touch switch, and can fit into the touch switch when it is close to the limit position.

[0011] In some embodiments, the housing is detachably mounted to the outside of the bracket via a connector.

[0012] In some embodiments, the connector is a bolt.

[0013] In some embodiments, the housing has a storage groove, and the head of the bolt is located in the storage groove.

[0014] In some embodiments, a mounting groove is provided on the inner side of the housing, the mounting groove extends along the axial direction of the housing, and the touch switch is disposed in the mounting groove.

[0015] In some embodiments, the detection structure further includes:

[0016] A support spring is provided, one end of which is connected to the movable plate, and the other end of which is connected to the bottom of the mounting groove.

[0017] In some embodiments, a plurality of support springs are provided, and each support spring is evenly distributed in the extension direction of the mounting groove.

[0018] In some embodiments, there are multiple detection structures, and each detection structure is evenly distributed along the axial direction of the housing.

[0019] In some embodiments, the independent suspension structure further includes:

[0020] An adjustment component is provided, through which the touch switch is mounted in the mounting slot, and the distance between the touch switch and the movable plate is adjusted.

[0021] In some embodiments, the adjusting component includes:

[0022] A threaded rod is provided, and a threaded hole is provided on the outer shell. The threaded rod is screwed into the threaded hole. The inner end of the threaded rod passes through the threaded hole, and its outer end is placed outside the outer shell. The touch switch is installed on the inner end of the threaded rod.

[0023] A rotating block is mounted on the outer end of the threaded rod.

[0024] In one or more specific embodiments, the beneficial effects of this utility model include at least the following:

[0025] By setting up a detection structure, as the torsion bar spring relaxes, the outer side of the torsion bar spring is easily squeezed against the movable plate during the car's operation. When the movable plate is squeezed, it moves and touches the touch switch, which activates the alarm's switching circuit, causing the alarm in the car to emit an alarm signal, thus achieving the effect of reminding the driver to detect vehicle abnormalities and have them repaired in time.

[0026] Furthermore, by rotating the rotating block, the threaded rod is driven to rotate. The rotation of the threaded rod causes the touch switch to move in the radial direction of the housing, thereby adjusting the initial distance between the touch switch and the movable plate. This achieves the effect of adjusting the sensitivity of the detection structure, which helps to cope with different qualified lateral deformation amplitudes of torsion bar springs.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0038] In the description of this application, the term "for example" is used to mean "used as an example, illustration, or description."

The following description is provided to enable any person skilled in the art to implement and use the present invention. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0039] Reference Figure 1 The independent suspension structure provided by this utility model is used in automobiles. This independent suspension structure includes a support block 1, a housing 2, and a detection structure 3. The support block 1 is mounted on the suspension bracket, and the housing 2 is detachably mounted on the outer side of the support block 1. The torsion bar spring is sleeved inside the housing 2, and the detection structure 3 is mounted on the inner side of the housing 2. The detection structure 3 includes an alarm, a touch switch 304 connected in series in the alarm's switching circuit, and a movable plate 303. A preset initial distance is maintained between the movable plate 303 and the touch switch 304. This initial distance ensures the normal operation of the torsion bar spring before fatigue damage and prevents accidental contact with the movable plate 303. The movable plate 303 is radially movably mounted on the housing 2, allowing it to move closer to or further away from the touch switch 304, and to engage with the touch switch 304 when approaching its extreme position. In other words, when the torsion bar spring is not fatigued, the movable plate 303 is in its initial position and will not contact the touch switch 304. The alarm's switching circuit is open, and the alarm does not sound. When the torsion bar spring is fatigued, it will push the movable plate 303 toward the touch switch 304. When the fatigue damage reaches its limit, the movable plate 303 approaches the limit position of the touch switch 304. At this time, the movable plate 303 is in contact with the touch switch 304, pushing the touch switch 304 to conduct the alarm's switching circuit, causing the alarm to sound an alarm signal.

[0040] To improve the ease of connection between the outer shell 2 and the bracket, the outer shell 2 is detachably installed on the outside of the bracket via a connector. This connector can be a bolt 201 or a clip. In this embodiment, the outer shell 2 is equipped with a bolt 201, and the outer shell 2 is connected to the support block 1 via the bolt 201. The bolt 201 facilitates the assembly and disassembly of the outer shell 2.

[0041] The outer casing 2 has a storage groove 202. The head of the bolt 201 is located in the storage groove 202. The storage groove 202 is used to place the head of the bolt 201. The head of the bolt 201 is embedded in the storage groove 202, which can minimize the protrusion of the head of the bolt 201 and thus prevent the bolt 201 from taking up space.

[0042] The inner side of the outer casing 2 is provided with a mounting groove 301, which extends along the axial direction of the outer casing 2. The touch switch 304 is disposed in the mounting groove 301. The detection structure 3 also includes a support spring 302, one end of which is connected to the movable plate 303, and the other end of which is connected to the bottom of the mounting groove 301. Thus, the support spring 302 is provided between the mounting groove 301 and the movable plate 303 to support the movable plate 303 without affecting its movement.

[0043] Furthermore, multiple support springs 302 are provided, and each support spring 302 is evenly distributed in the extension direction of the mounting groove 301, so as to better install the movable plate 303.

[0044] To improve the detection effect and ensure that improper movement of the torsion bar spring in any direction can trigger an alarm, multiple detection structures 3 are provided, and each detection structure 3 is evenly distributed along the axial direction of the outer shell 2.

[0045] Alternatively, the alarm can be an audible and visual alarm, a flashing light, or a buzzer, etc.

[0046] In some embodiments, refer to Figures 1-3 The outer casing 2 is provided with a detection structure 3, which includes a mounting groove 301 opened on the inner side of the outer casing 2 and a touch switch 304 located in the mounting groove 301. A support spring 302 is installed on the outer casing 2 through the mounting groove 301. A movable plate 303 is installed on one end of the support spring 302. The movable plate 303 is movably connected to the outer casing 2 through the mounting groove 301. Multiple support springs 302 are provided. According to the above technical solution, specifically, as the torsion bar spring relaxes, during the driving process, the outer side of the torsion bar spring is easily squeezed against the movable plate 303. When the movable plate 303 is squeezed, the movable plate 303 moves and touches the touch switch 304, thereby causing the flashing light in the car to flash, thus achieving the effect of reminding the driver to find the vehicle abnormality and repair it in time.

[0047] It should be noted that a flashing light needs to be installed in the center console of the car. The circuit connection between the flashing light and the touch switch 304 can be reasonably set according to the actual situation, and the signal transmission method of the two is existing technology.

[0048] Furthermore, in order to adjust the accuracy range to suit different working conditions, the independent suspension also includes an adjustment component. The touch switch 304 is installed in the mounting slot 301 through the adjustment component, and the distance between the touch switch 304 and the movable plate 303 is adjusted through the adjustment component.

[0049] Specifically, the adjusting component includes a threaded rod 4 and a rotating block 5. The outer casing 2 has a threaded hole, the threaded rod 4 is screwed into the threaded hole, the inner end of the threaded rod 4 passes through the threaded hole, and its outer end is placed outside the outer casing 2. The touch switch 304 is installed at the inner end of the threaded rod 4; the rotating block 5 is installed at the outer end of the threaded rod 4.

[0050] In some embodiments, refer to Figure 3 A threaded rod 4 is threadedly connected to the outer casing 2. A touch switch 304 is installed at one end of the threaded rod 4, which is located in the mounting groove 301. A rotating block 5 is installed at the other end of the threaded rod 4. By rotating the rotating block 5, the threaded rod 4 is rotated. The rotation of the threaded rod 4 causes the touch switch 304 to move, thereby achieving the effect of adjusting the sensitivity of the detection structure 3, which helps to cope with different transverse deformation amplitudes of torsion bar springs.

[0051] During operation, as the torsion bar spring relaxes, its outer side easily presses against the movable plate 303 while the car is in motion. When the movable plate 303 is pressed, it moves and touches the touch switch 304, causing the flashing light inside the car to blink, thus alerting the driver to detect vehicle abnormalities and perform timely repairs. By rotating the rotating block 5, the threaded rod 4 is rotated, which in turn moves the touch switch 304, thereby adjusting the sensitivity of the detection structure 3 and helping to handle different acceptable lateral deformation ranges of the torsion bar spring.

[0052] In addition to the aforementioned independent suspension structure, this utility model also provides a car that includes the independent suspension structure. For the structure of other parts of the car, please refer to the prior art, which will not be described in detail here.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0054] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
