Description

Technical Field

[0001] The present invention relates to the technical field of probes, and specifically to a probe assembly for a vehicle identification sensor. Background Art

[0002] In the fields of intelligent transportation and vehicle safety technologies, vehicle identification sensors (such as radar, lidar probes) are core components for realizing functions such as automatic anti-collision, vehicle distance monitoring, and blind spot detection. Their reliability and ease of use directly affect the active safety performance of vehicles.

[0003] Most probes are directly pasted on the vehicle housing (such as the bumper, side of the vehicle body) using colloid. This method relies on the viscosity of the colloid for fixation. During installation, precise positioning is required and waiting for the colloid to cure is needed, resulting in low efficiency; during disassembly, a heating tool is required to soften the colloid, and improper operation is likely to cause scratches on the probe surface or colloid residue, with high cleaning costs; there are also rigidly installed probes directly exposed outside the vehicle, without buffer protection during collisions, easily causing the housing to crack, the internal circuit to break, or the antenna to shift, resulting in ranging failure or function failure. Therefore, a probe assembly for a vehicle identification sensor is needed to solve the problems existing in the prior art. Summary of the Invention

[0004] The purpose of the present invention is to provide a probe assembly for a vehicle identification sensor to solve the problems raised in the above background art.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A probe assembly for a vehicle identification sensor includes a radar induction probe and an installation housing installed on the vehicle. The installation housing is sleeved outside the radar induction probe. A torsional disassembly and assembly mechanism is provided inside the installation housing. The torsional disassembly and assembly mechanism includes an anti-extrusion plate, a buffer spring, and a rotating convex block. The anti-extrusion plate is movably connected to the inner cavity of the installation housing. One end of the buffer spring is fixed to the end face of the anti-extrusion plate. The rotating convex block is fixed to the housing of the radar induction probe.

[0006] Preferably, buffer guide grooves are formed on the inner wall of the installation housing. A positioning convex block is fixed to the side surface of the anti-extrusion plate, and the positioning convex block is slidably connected to the buffer guide grooves of the installation housing.

[0007] Preferably, an annular positioning groove is formed on the inner wall of the installation housing. The annular positioning groove intersects with the buffer guide grooves to form a cross groove. Two torsional operation ports communicating with the annular positioning groove are formed on the outer surface of the installation housing. An anti-slip rubber pad is fixedly embedded in one of the torsional operation ports.

[0008] Preferably, an annular accommodation groove is formed inside the anti-extrusion plate, and an assembly port is formed on the rear end face of the anti-extrusion plate.

[0009] Preferably, the assembly port is communicated with the annular receiving groove, and both the rotating protrusion and the annular receiving groove are movably matched with the rotating protrusion.

[0010] Preferably, the front end of the mounting shell is provided with a front opening, the rear end of the mounting shell is provided with a removal opening, the radar sensing probe is engaged with the front opening of the mounting shell, the caliber of the removal opening is larger than the diameter of the radar sensing probe, and a connecting wire is passed through the rear end of the radar sensing probe.

[0011] The present invention provides a vehicle identification sensor probe assembly, which has the following advantages compared with the prior art:

[0012] Beneficial effects:

[0013] Through the torsion disassembly and assembly mechanism, when the probe is squeezed, the anti-extrusion plate slides inward along the buffer guide groove, and absorbs the impact force through the compression of the buffer spring, converting the hard collision into elastic deformation. Compared with the traditional rigid installation, it can withstand a certain instantaneous impact force, thereby preventing the probe from breaking the shell, breaking the internal circuit, deviating the antenna and falling off the vehicle body due to impact. After the squeezing force disappears, the spring rebound force pushes the anti-extrusion plate to automatically reset, ensuring that the probe is always in the initial detection position, avoiding the ranging error caused by displacement, and ensuring the reliability of the reversing radar, automatic collision avoidance and other functions.

[0014] Through the anti-extrusion plate and rotating protrusion, the radar sensing probe is connected to the anti-extrusion plate through the twist locking structure of the rotating protrusion + annular receiving groove. There is no need to rely on glue throughout the process. Only two steps, insertion and twisting, are required during installation, which makes disassembly and assembly efficient. It also avoids the tedious process of heating to soften the colloid and cleaning residual glue stains during traditional glue disassembly, thereby reducing the risk of damage to the probe surface.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0021] See also Figures 1-4 The present invention provides a vehicle identification sensor probe assembly, comprising a radar sensing probe 2 and a mounting shell 1 mounted on a vehicle, the mounting shell 1 is sleeved on the outside of the radar sensing probe 2, a torsion disassembly mechanism 4 is arranged inside the mounting shell 1, the torsion disassembly mechanism 4 comprises an anti-extrusion plate 5, a buffer spring 6 and a rotating protrusion 12, after the extrusion force disappears, the buffer spring 6 uses the rebound force to push the anti-extrusion plate 5 to automatically reset, so that the radar sensing probe 2 returns to the initial detection position, the anti-extrusion plate 5 is movably connected in the inner cavity of the mounting shell 1, one end of the buffer spring 6 is fixed on the end face of the anti-extrusion plate 5, the rotating protrusion 12 is fixed on the shell of the radar sensing probe 2, a buffer guide groove 9 is opened on the inner wall of the mounting shell 1, a positioning protrusion 7 is fixed on the side surface of the anti-extrusion plate 5, and the positioning protrusion 7 is slidably connected in the buffer guide groove 9 of the mounting shell 1, when the radar sensing probe 2 is squeezed, the anti-extrusion plate 5 can slide inward along the buffer guide groove 9, compress the buffer spring 6, absorb the impact force, and prevent the radar sensing probe 2 from being damaged due to hard collision.

[0022] Further as Figure 3 As shown, it is worth specifically explaining that an annular positioning groove 8 is provided on the inner wall of the mounting shell 1, and the annular positioning groove 8 intersects with the buffer guide groove 9 to form a cross groove, and the outer surface of the mounting shell 1 is provided with two twisting operation openings 15 connected with the annular positioning groove 8, and a non-slip rubber pad 10 is embedded and fixed inside one of the twisting operation openings 15, and an annular receiving groove 14 is provided inside the anti-extrusion plate 5, and an assembly opening 13 is provided on the rear end face of the anti-extrusion plate 5, and the assembly opening 13 is connected with the annular receiving groove 14, and the rotating protrusion 12 and the annular receiving groove 14 are both movably matched with the rotating protrusion 12, and the rotating protrusion 12 is placed into the annular receiving groove 14 along the assembly opening 13 of the anti-extrusion plate 5 and twisted, so as to realize the assembly and locking of the radar sensing probe 2 and the anti-extrusion plate 5, and ensure that the two are firmly connected.

[0023] Furthermore, as Figure 1 shown, it is worth specifically explaining that a front through-hole 11 is provided at the front end of the installation housing 1, and a removal relief opening 16 is provided at the rear end of the installation housing 1. The radar induction probe 2 is snap-fitted with the front through-hole 11 of the installation housing 1. The diameter of the removal relief opening 16 is larger than the diameter of the radar induction probe 2. A connecting wire 3 is passed through the rear end of the radar induction probe 2. The removal relief opening 16 is provided at the rear end of the installation housing 1, and its diameter is larger than the diameter of the radar induction probe 2, providing sufficient space for the removal of the probe when disassembling the radar induction probe 2.

[0024] This solution has the following working process: Before use, the installation housing 1 is pre-fixed to the inner wall of the vehicle housing with glue. When assembling the radar induction probe 2 with the installation housing 1, the front end of the radar induction probe 2 is sequentially placed into the removal relief opening 16 and the front through-hole 11 of the installation housing 1. At this time, the radar induction probe 2 is placed into a preset hole in the vehicle housing. During the process of the radar induction probe 2 being placed into the installation housing 1, the rotating convex block 12 on the housing of the radar induction probe 2 is placed into the annular accommodation groove 14 along the assembly opening 13 of the anti-extrusion plate 5. Subsequently, the radar induction probe 2 is twisted so that its rotating convex block 12 is twisted into the annular accommodation groove 14 that deviates from the assembly opening 13. In this way, the radar induction probe 2 can be combined with the anti-extrusion plate 5, and the sliding anti-extrusion plate 5 has a buffering effect under the elastic force of the buffer spring 6. In this way, when the radar induction probe 2 in the hole of the vehicle housing is squeezed, it can buffer and move towards the inside of the vehicle housing, and automatically reset using the resilience of the buffer spring 6 when the extrusion force disappears, thereby preventing the radar induction probe 2 from being damaged due to hard collision and the trouble of falling off the vehicle housing;

[0025] When disassembling the radar induction probe 2, pull the radar induction probe 2 inward, driving the anti-extrusion plate 5 to slide inward along the buffer guide groove 9 into the annular positioning groove 8. Subsequently, twist the anti-extrusion plate 5 so that the positioning convex block 7 on the anti-extrusion plate 5 slides along the annular positioning groove 8 to the position of the twisting operation port 15. The anti-slip rubber pad 10 in one twisting operation port 15 presses against the positioning convex block 7 and restricts the anti-extrusion plate 5 from twisting. At this time, twisting the radar induction probe 2 can control the rotating convex block 12 to rotate in the annular accommodation groove 14 of the anti-extrusion plate 5 until the rotating convex block 12 rotates to the assembly opening 13. In this way, the radar induction probe 2 can be pulled out from the anti-extrusion plate 5 along the assembly opening 13. The flexible assembly method of the radar induction probe 2 and the anti-extrusion plate 5 with elastic performance provides convenience for quick disassembly, and the fixing method of the radar induction probe 2 to the vehicle housing is a traditional glue fixing method, which can reduce the trouble of residual colloid on the surface of the radar induction probe 2.
