Detailed Description

It is easily understood that, according to the technical solution of the present invention, a plurality of alternative structural modes and implementation modes can be proposed by those skilled in the art without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical solutions of the present invention, and should not be considered as limiting or restricting the technical solutions of the present invention in their entirety or in any other way.

The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms. Furthermore, the terms "first," "second," "third," and the like are used for descriptive and descriptive purposes only and not for purposes of indication or implication as to the relative importance of the respective components.

Reference is made to fig. 1, 2 and 3, which show respectively a schematic perspective view of a telescopic support according to the invention, its two-dimensional view in a normal operating condition and its two-dimensional view in a compressed condition.

Telescopic bracket 100 is used for the installation of automobile-used part, wherein, telescopic bracket 100 has and is used for connecting part connecting portion 1, the sleeve 2 of cylindricality, spring 3, slider 4 of automobile-used part and is used for being connected to vehicle body and fixed position's vehicle body connecting portion 5, wherein, part connecting portion 1 with vehicle body connecting portion 5 is followed the longitudinal direction of sleeve 2 arranges in the both sides of sleeve 2, spring 3 with slider 4 arranges in inside sleeve 2, part connecting portion 1 spring 3 slider 4 and vehicle body connecting portion 5 are in connect gradually each other in the longitudinal direction, and spring 3 orientation the one end of part connecting portion 1 for sleeve 2 fixed position.

With the above technical solution, it should be understood that, in an initial state or a normal working state, the spring of the retractable bracket is in a state with a large longitudinal length, so that a vehicle component, such as a vehicle radar, can have a longest extension range, which is convenient for the development of normal work (sending and receiving signals). When an impact occurs, the installed vehicle parts, such as vehicle electronic parts, such as vehicle-mounted radar, can perform a retracting action due to the compression action of the spring 3, so that the impact force is relieved and the vehicle parts are protected. When the external collision force disappears, the spring 3 extends to the initial state due to the inherent characteristics of the spring, and then the vehicle part is driven to return to the initial position to continue to work normally. It should also be understood that the body attachment portion 5 is intended to be attached to the vehicle body, that is, the body attachment portion 5 may be directly attached to the vehicle body or indirectly attached (e.g., via a bracket) to the vehicle body. Furthermore, the expression "the end of the spring 3 facing the part connection 1 is positionally fixed relative to the sleeve 2" means that the compression of the spring 3 is actually brought about by its other end, while this end of the spring 3 and thus the entire part connection 1 cannot have a relative movement relative to the sleeve 2 (including the first nut 6 mentioned below) as a result of the telescopic movement of the spring 3, so that the risk of the connected vehicle part colliding with the sleeve 2 or the first nut 6 during compression is avoided. Furthermore, the slide 4 can substantially completely occupy the inner space of the sleeve 2 in width (while ensuring that the slide 4 can slide properly), so as to maintain a high stability of movement during its sliding, and in particular to be able to have a stable movement characteristic even under strong spring forces. The slider 4 is able to slide inside the sleeve 2 during the extension and retraction of the spring 3. The vehicle-mounted radar may be a long-range radar.

As can also be seen from the drawings, the telescopic bracket 100 further has a first nut 6, the part connecting portion 1 is a bolt, the first nut 6 is disposed at an end of the sleeve 2 facing the part connecting portion 1 and closes an inner space of the sleeve 2, so that it is possible to provide a maximum fixing position for the spring 3 and to ensure that the spring does not fall out of the inner space, and it has a large spring force bearing capacity in combination with the sleeve 2. Furthermore, the screw projects into the first nut 6. The bolt may specifically be a hexagon socket bolt, for example, facilitating the installation of the vehicle radar. The mode low in manufacturing cost, simple structure of the threaded connection of bolt and first nut to it is firm to connect, is difficult for receiving the influence of external impact, and easy dismouting in addition still. Still specifically, the right end face of the bolt is flush with the right end face of the first nut 6 to make full use of the installation space in the first nut to ensure the stability of installation, and the assembly of the spring 3 is not affected. The left end of the first nut 6 can be flush with the left end of the sleeve 2, so that the attractiveness and compactness are guaranteed.

Optionally, the first nut 6 is welded to the sleeve 2. For this purpose, the first nut 6 may have a welding hole 61 for welding on its outer circumference, and the sleeve 2 may have a corresponding welding opening 21 on its circumferential wall. The welding openings 21 are, for example, uniformly distributed around their central axis at 90 ° on the outer circumference of the sleeve 2 and are configured as circular holes, which is simple to produce, is inexpensive to weld and nevertheless provides a secure connection. Similarly, welded connections are characterized by low cost in money and time, stable connections and good durability, and do not appreciably damage the original structure of the parts to be welded.

As can be seen from the right side of the figure, the retractable bracket 100 further has a connecting rod 7, the connecting rod 7 is respectively connected with the slider 4 and the vehicle body connecting portion 5, an opening is opened at one end of the sleeve 2 facing the vehicle body connecting portion 5, and the connecting rod 7 passes through the opening. According to the technical scheme, the connecting rod 7 extends into the inner space of the sleeve 2 more in the compression process of the spring 3, and the connecting rod 7 is used as a transition piece between the vehicle body connecting part 5 and the sliding block 4, so that the relative movement between the sleeve 5 and the vehicle body connecting part 5 is supported in a low manufacturing cost and a compact structure mode.

Furthermore, it is also exemplarily shown that the end of the connecting rod 7 connected to the vehicle body connecting portion 5 is configured with a thread 71, the vehicle body connecting portion 5 includes a second nut 51 and a washer 52 both fitted on the thread 71, and the washer 52 is disposed between the sleeve 2 and the second nut 51, and the vehicle body can be connected between the washer 52 and the second nut 51. Similar to before, the mode of threaded connection realizes simply, connects firmly and easy dismouting. In addition, the washer 52 takes on the task of contacting the right end of the sleeve 2 under compression of the spring 3, thereby eliminating contact with the second nut 51 and increasing its service life. Instead, the replacement of the gasket 52 is much easier and less costly. It should be understood that the distance between the second nut 51 and the washer 52 can be adjusted according to the parts to be connected to achieve the most stable connection. When the vehicle component is subjected to an external collision force, as shown in fig. 3, the component connecting portion 1 and the sleeve 2 compress the spring 3 backward until the spacer 52 contacts the sleeve 2 (depending on the magnitude of the collision force), which serves to reduce the collision force on the vehicle component to protect the vehicle component. The left end of the thread 71 may be configured to be flush with the left end of the washer 52, and the right end of the thread 71 may be configured to be beyond the right end of the second nut 51, so as to provide a stable impact resistance and an adjustment margin of a receiving space therebetween, respectively.

It should also be mentioned that the spring 3 is configured to have a compression at all times within the sleeve 2, i.e. the spring 3 has already a certain compression in the initial state, so that a restraining force in the axial direction is ensured. This effect can be achieved, for example, by the length of the slide 4 and/or the length of the receiving space of the sleeve 2, although the choice of the spring 3 itself (for example its length in the relaxed state) can also be taken into account. In addition, the sliding block 4 and the connecting rod 7 can be constructed as solid cylinders, so that the movement of the sliding block and the connecting rod during the extension and contraction process is stable, the durability and the supporting strength are high, and meanwhile, the structure is simple and the realization cost is low. The telescoping support 100 may be made of metal.

It should be understood that the retractable stand 100 of the present invention can be mounted on various vehicles, including gasoline vehicles, diesel vehicles, cars, trucks, buses, hybrid vehicles, pure electric vehicles, etc. Accordingly, the subject matter of the present invention is also directed to protecting various vehicles equipped with the retractable stand 100 of the present invention.

It should be understood that all the above preferred embodiments are exemplary and not restrictive, and that various modifications and changes in the specific embodiments described above may be made by those skilled in the art without departing from the spirit of the invention.
