Description

Technical Field

[0001] The utility model relates to the technical field of vehicle collision warning, in particular to a vehicle collision warning device. Background Art

[0002] The working principle of radar sensors in the automotive field is to transmit FM continuous waves (FMCW) through antennas. There is a time interval between the echo received after the target is reflected and the transmitted wave. This interval can be used to calculate the distance of the target. According to the Doppler principle, the frequency difference between the transmitted and reflected signals is analyzed by the signal processor, and the speed of the target relative to the radar can be accurately measured, thereby achieving separation and tracking of multiple targets.

[0003] In terms of application, radar has experienced a process of gradual development from short-range to medium-range and long-range. Early short-range radar technology was mainly used for basic safety and auxiliary applications, such as anti-lock braking systems and cruise speed systems. With the advancement of technology, long-range radar technology has gradually been introduced into advanced safety applications, including electronic stability control systems (ESC), blind spot detection (BSD), forward collision warning (FCW), rear cross traffic warning (RCW), lane departure warning (LDW), etc. By 2016, high-resolution short-range, medium-range, and long-range radar technologies have been widely used in advanced driver assistance systems (ADAS) such as adaptive cruise control (ACC), automatic emergency braking (AEB), blind spot detection, and lane change assistance. Since 2016, high-resolution short-range, medium-range, and long-range hybrid mode radar sensors have become the core technology for achieving L3 level autonomous driving safety applications.

[0004] In the prior art, during the use of vehicle collision warning, it is not possible to conveniently install and adjust the angle position of the radar sensor harness and the overall sensor; therefore, we make improvements to this and propose a vehicle collision warning device.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments.

[0028] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the present invention to be protected, but only represents some embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. It should be noted that the embodiments of the present invention and the features and technical solutions in the embodiments can be combined with each other without conflict.

[0029] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0030] like Figure 1-4As shown, this embodiment proposes a vehicle collision warning device, including a radar sensor 1, a limit groove 4 is provided at the outer end of the radar sensor 1, a connecting support 2 is provided at the outer end of the limiting groove 4, a positioning seat 3 is provided at the outer end of the connecting support 2, a through pipe 7 is provided at the rear end of the positioning seat 3, an embedding groove 6 is provided at the lower end of the through pipe 7, a linkage rope 8 is provided at the inner ends of the embedding groove 6 and the through pipe 7, the lower end of the linkage rope 8 is fixed to a wire collection rod 9, an end plate 10 and a groove 11 are provided at the rear end of the wire collection rod 9, and a threaded rod 12 is provided at the inner end of the wire collection rod 9.

[0031] The limiting groove 4 is embedded and installed in the front end of the connecting support 2 and the positioning seat 3, and a linkage rod 5 is provided between the connecting support 2 and the positioning seat 3. The through pipe 7 penetrates the inner surfaces of the upper and lower ends of the positioning seat 3, and the lower end of the through pipe 7 is connected with the embedded groove 6. The embedded groove 6 is embedded and installed in the rear end inner surface of the connecting support 2. The linkage rope 8 penetrates the embedded groove 6 and the through pipe 7, and the head end of the linkage rope 8 is wrapped and connected with the wiring terminal of the radar sensor 1. The linkage rope 8 is wrapped around the outer end of the wire collection rod 9, and the groove 11 is embedded and installed in the rear end inner surface of the wire collection rod 9. The inner end of the groove 11 is wrapped with an end plate 10, and the end plate 10 is fixed to the inner end of the connecting support 2. A threaded groove is connected between the inner end of the wire collection rod 9 and the threaded rod 12, and a movable gap is provided between the wire collection rod 9 and the end plate 10.

[0032] When installing the radar sensor 1 on different vehicles, there are certain settings for the ultrasonic emission angle of the radar sensor 1. During this process, the current radar sensor 1 can only set one angle and cannot conveniently and accurately set the emission angle according to the overall vehicle model. At this time, the radar sensor 1 is moved from top to bottom along the positioning seat 3 and the limiting groove 4 in the connecting support 2. When the radar sensor 1 moves to the lower end, the wire collection rod 9 that is not connected to the end plate 10 is rotated at this time, which can facilitate the adjustment of the angle between the positioning seat 3 and the connecting support 2. After the angle is determined, it can be rotated along the threaded pattern in the wire collection rod 9 through the threaded rod 12. At this time, the end plate 10 and the wire collection rod 9 are connected to each other and are embedded through the groove 11, so that the angle of the radar sensor 1 can be conveniently fixed.

[0034] The head end of the linkage rope 8 is connected to the wiring terminal of the radar sensor 1, which can facilitate the elasticity of the elastic rod 13. When the connecting harness is installed and fixed on the vehicle frame, it can avoid excessive positioning and winding to cause the line flow to be unsmooth;

[0035] At the same time, the elastic rod 13 is used to position each circle of the connecting wire harness, so that the installation positioning of the wire harness part of the radar sensor 1 can be improved.

[0036] When the present application is in use: the head end of the linkage rope 8 is connected to the wiring terminal of the radar sensor 1, and the radar sensor 1 is moved from top to bottom along the positioning seat 3 and the limiting groove 4 in the connecting support 2. When the radar sensor 1 moves to the lowermost end, the wire collection rod 9 that is not connected to the end plate 10 is rotated at this time, which can facilitate the adjustment of the angle between the positioning seat 3 and the connecting support 2. After the angle is determined, it can be rotated along the threaded pattern in the wire collection rod 9 through the threaded rod 12. At this time, the end plate 10 and the wire collection rod 9 are interconnected and embedded through the groove 11, so that the angle of the radar sensor 1 can be conveniently fixed.

Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
