[0036] The utility model discloses a vehicle distance detection device, as shown in the accompanying Figures 1 to 3 The device is installed in the preset mounting hole 101 of the vehicle body 1, and is used for measuring the distance between the vehicle and the obstacle. The device comprises a positioning sleeve 2, a limiting sleeve 3, an adjusting part 4, a mounting part 5, an end cover 6 and a back cover 7. The positioning sleeve 2 penetrates into the mounting hole 101 of the vehicle body 1 and is connected and fixed with the vehicle body 1 through the connection of the limiting sleeve 3. The vehicle body 1 in the embodiment can be a vehicle body covering part of the vehicle, for example, a front bumper or a rear bumper. The positioning sleeve 2 further forms a containing cavity 201 inside, and the limiting sleeve 3, the adjusting part 4 and the mounting part 5 are all arranged in the containing cavity 201. The end cover 6 and the back cover 7 are respectively fixed to the two ends of the positioning sleeve 2 to cover the ports at the two ends of the positioning sleeve 2.

[0037] As shown in the accompanying Figure 7 A plurality of protruding limiting parts 31 are arranged in the annular surface of the limiting sleeve 3 in an array. Preferably, the limiting sleeve 3 can be an injection molded part, so that the limiting parts 31 have elasticity relative to the movement of the axis of the limiting sleeve 3. Similarly, the positioning sleeve 2, the adjusting part 4, the mounting part 5, the end cover 6 and the back cover 7 can all be injection molded parts. Further, the limiting sleeve 3 is provided with a hollow through hole on both sides of the limiting part 31, so as to reduce the rigidity of the two sides of the limiting part 31, thereby improving the elasticity of the limiting part 31 relative to the movement of the axis of the limiting sleeve 3.

[0038] As shown in the accompanying Figure 8 The annular surface of one end of the positioning sleeve 2 is provided with a blocking part 21, and the outer diameter of the blocking part 21 is greater than the preset mounting hole 101 of the vehicle body 1. The annular surface of the positioning sleeve 2 is distributed with a plurality of limiting holes 202. Referring to the accompanying Figures 4 to 6When the positioning sleeve 2 is installed, the positioning sleeve 2 is inserted through the installation hole 101, and the blocking part 21 is blocked on the outer surface of the vehicle body 1. Then, the limiting sleeve 3 is embedded into the accommodating cavity 201 of the positioning sleeve 2, and each limiting part 31 of the limiting sleeve 3 is pressed into the accommodating cavity 201. When the limiting sleeve 3 is embedded into the accommodating cavity 201 until each limiting part 31 passes through each limiting hole 202, the limiting part 31 and the blocking part 21 clamp the vehicle body 1 to fix the positioning sleeve 2 relative to the vehicle body 1. Further, at least one rubber ring 22 is sleeved on the part of the positioning sleeve 2 located in the vehicle body 1. Each limiting part 31 of the limiting sleeve 3 is pressed against the rubber ring 22, and the limiting part 31 and the blocking part 21 clamp the vehicle body 1 and the rubber ring 22. The limiting part 31 and the blocking part 21 can clamp the vehicle body 1 more tightly, so that the positioning sleeve 2 is more firmly fixed on the vehicle body 1.

[0039] As shown in the accompanying drawings, Figure 7 and 10 The limiting sleeve 3 is provided with a rotating hole 301 on each side, and the mounting part 5 is provided with a rotating pin 53 on each side. The two rotating pins 53 are embedded into the two rotating holes 301, respectively, so that the mounting part 5 rotates relative to the limiting sleeve 3 and the positioning sleeve 2, that is, relative to the vehicle body 1, with the rotating pin 53 as the swing axis. The structure in which the rotating pin 53 is embedded into the rotating hole 301 can be that the inner wall of the limiting sleeve 3 is provided with a rotating column 33 on each side, and the two rotating holes 301 are arranged on the two rotating columns 33, respectively. The side wall of the rotating column 33 facing the outer side of the positioning sleeve 2 is provided with a gap 302, and the width of the gap 302 is slightly smaller than the diameter of the rotating pin 53. The rotating pin 53 is embedded into the rotating hole 301 in a hard pressing manner along the gap 302. During the process, the rotating column 33 is pressed by the rotating pin 53 on both sides of the gap 302 to expand the gap 302. After the rotating pin 53 is embedded into the rotating hole 301, the rotating column 33 restores on both sides of the gap 302 to limit the rotating pin 53 in the rotating hole 301, so that the mounting part 5 can only swing in the accommodating cavity 201.

[0040] As shown in the accompanying drawings, Figure 1 , 5As shown in Figure 7, the end cap 6 has several first snap-fit ​​portions 61 on the side facing the positioning sleeve 2. The positioning sleeve 2 has a second snap-fit ​​portion 32 axially fixed in the accommodating cavity 201. The second snap-fit ​​portion 32 can be an annular structure. When installing the end cap 6, each first snap-fit ​​portion 61 is inserted into the accommodating cavity 201 along the port of the positioning sleeve 2 from the outside of the vehicle body 1, so that each first snap-fit ​​portion 61 is engaged and locked with the second snap-fit ​​portion 32, thereby sealing the port of the positioning sleeve 2 facing the outside of the vehicle body 1. In addition, the second snap-fit ​​portion 32 can also be integrally formed in the limiting sleeve 3. When installing the end cap 6, each first snap-fit ​​portion 61 is inserted into the limiting sleeve 3 from the port of the positioning sleeve 2, so that each first snap-fit ​​portion 61 is engaged and locked with the second snap-fit ​​portion 32. In this structure, the end cap 6 can seal the positioning sleeve 2 while also pulling the limiting sleeve 3 towards the vehicle body 1, further improving the firmness of the fixing between the positioning sleeve 2 and the vehicle body 1.

[0041] As attached Figure 9 As shown, the adjusting component 4 has a rotating shaft 41 and a screw 42 that are perpendicular to each other. Specifically, the adjusting component 4 is formed into a T-shaped structure. The screw 42 is located in the middle of the rotating shaft 41, and the screw 42 is adapted to a spiral connecting nut 43.

[0042] As attached Figure 10 As shown, one end of the mounting component 5 is fixed with a detection unit 8 for detecting obstacles. Specifically, the detection unit 8 may include a circuit board 81 and a millimeter-wave radio frequency chip 82, with the millimeter-wave radio frequency chip 82 integrated on the circuit board 81. The end face of the other end of the mounting component 5 is used to mount a laser unit (not shown in the attached figure). Specifically, the laser unit is a laser lamp that emits a linear light source, and the laser unit may be a cylindrical structure.

[0043] Please refer to the appendix. Figure 11 12. Mounting component 5 includes a front shell 51 and a rear shell 52. The front shell 51 is provided with a placement groove 501, and the bottom surface of the front shell 51 within the placement groove 501 is provided with a through clearance opening 502. The detection unit 8 is embedded into the placement groove 501, so that the circuit board 81 abuts against the bottom surface of the placement groove 501, and the millimeter-wave radio frequency chip 82 corresponds to the side or center of the clearance opening 502. One end face of the rear shell 52 is provided with a protruding pressing part 523. When the rear shell 52 is fixed to the front shell 51, the pressing part 523 is inserted into the placement groove 501 and the circuit board 81 of the detection unit 8 is pressed and fixed to the bottom surface of the placement groove 501. After fixing the rear shell 52 and the front shell 51, the detection unit 8 is fixed into the mounting component 5, and the detection unit 8 is located in the end of the positioning sleeve 2 facing outward from the vehicle body 1.

[0044] The rear cover 52 is also provided with a first through hole 503 that runs through both ends, through which the wires connecting the detection unit 8 pass out of the mounting piece 5. (See attached...) Figure 4 and 6, the end cover 6 can be connected with the positioning sleeve 2 by screwing, so that the end cover 6 encapsulates the positioning sleeve 2 at the port of the vehicle body. The back cover 7 is further provided with a second through hole 701 in the center, and the line connected with the detection unit 8 is led out from the first through hole 503 and then from the second through hole 701 to the outside of the accommodating cavity 201. In addition, the end surface of the rear shell 52 away from the pressing portion 523 is further provided with a fixing hole 504, and the fixing hole 504 and the first through hole 503 are in communication. The detection unit 8 is further provided with a light transmission hole in the center of the circuit board 81, and the millimeter wave radio frequency chip 82 is located on one side of the light transmission hole, or the light transmission hole is located on the side edge of the circuit board 81, and the millimeter wave radio frequency chip 82 is located in the center of the circuit board 81. The laser unit is inserted into the fixing hole 504 in a clearance fit to achieve installation, so that the light of the laser unit is sequentially led out from the first through hole 503, the light transmission hole, and then out of the positioning sleeve 2, forming a light ray emitted from the mounting piece 5 to the outside of the vehicle body 1. After adjusting the angle of the mounting piece 5 based on the light ray, the angle of the millimeter wave emitted by the detection unit 8 can be adjusted. Moreover, after adjustment, the laser unit can be pulled out of the fixing hole 504, and the back cover 7 is fixed to the positioning sleeve 2, so that the utilization rate of the laser unit can be improved. It is worth mentioning that the diameter of the light transmission hole of the circuit board 81 is wide enough, so that when the laser unit is inserted into the fixing hole 504, the line connected with the detection unit is pressed against the side wall of the fixing hole, and the laser is not affected when being emitted from the light transmission hole.

[0045] With reference to the accompanying drawings Figure 11 and 12 , the end surface of the front shell 51 away from the fixed millimeter wave radio frequency chip 82 is provided with a recessed first arc-shaped groove 511, and the front shell 51 is further provided with a first accommodation groove 512 penetrating to the outside of the front shell 51 at the middle position of the first arc-shaped groove 511. The end surface of the rear shell 52 is provided with a recessed second arc-shaped groove 521, and the rear shell 52 is further provided with a second accommodation groove 522 penetrating to the outside of the front shell 51 at the middle position of the second arc-shaped groove 521. After the front shell 51 and the rear shell 52 are connected and fixed, the first arc-shaped groove 511 and the second arc-shaped groove 521 are combined to form a connecting hole for arranging the rotating shaft 41 of the adjusting piece 4, and the first accommodation groove 512 and the second accommodation groove 522 are combined to form an accommodation opening 502 for swinging the screw rod 42 of the adjusting piece 4. With reference to the accompanying drawings Figure 6After the rotating pin 53 of the front housing 51 is inserted into the rotating hole 301 of the limiting sleeve 3, the rotating shaft 41 is first embedded in the first arc-shaped groove 511, and one end of the screw 42 passes through the waist-shaped hole 203 of the positioning sleeve 2. Then, the second arc-shaped groove 521 of the rear housing 52 corresponds to the first arc-shaped groove 511 of the front housing 51, so that the first arc-shaped groove 511 and the second arc-shaped groove 521 combine to restrict the adjusting member 4 in the connecting hole. At the same time, the first clearance groove 512 and the second clearance groove 522 combine to restrict the screw 42 in the clearance opening 502, so that the rotating shaft 41 of the adjusting member 4 is embedded in the connecting hole and rotates, and the screw 42 passes through the clearance opening 502 to the outside of the mounting member 5. In this way, adjusting members 4 are connected to both ends of the mounting member 5, so that the rotating shaft 41 of the two adjusting members 4 is restricted to rotate in the mounting member 5, and the screw 42 swings relative to the mounting member 5 and the positioning sleeve 2 after passing through the waist-shaped hole 203 of the positioning sleeve 2.

[0046] In addition, after the screw 42 passes through the oblong holes 203 on both sides of the positioning sleeve 2, it is also screwed to the nut 43. When one of the screws 42 is restricted by the nut 43 and cannot move into the positioning sleeve 2 relative to the oblong hole 203, but can only swing relative to the mounting part 5, rotating the nut 43 of the other screw 42 inwards towards the positioning sleeve 2 will cause the other screw 42 to move outwards from the positioning sleeve 2 and swing, thereby changing the angle of the mounting part 5 relative to the positioning sleeve 2. See attached figure for details. Figure 4 For example, after the upper screw 42 is restricted from moving into the positioning sleeve 2 by the upper nut 43, the lower nut 43 is rotated in the direction of tightening the positioning sleeve 2, which can drive the lower screw 42 to move downward and outward from the positioning sleeve 2, thereby changing the angle of the mounting part 5 relative to the positioning sleeve 2. In other words, by rotating the nut 43, the end of the mounting part 5 away from the detection unit 8 can be pulled to rotate.

[0047] After fixing the positioning sleeve 2 to the vehicle body 1, the laser unit is inserted into the fixing hole 504 of the mounting part 5, so that the light is emitted from the mounting part 5 through the positioning sleeve 2 to the outside of the vehicle body 1. By rotating the nuts 43 connected to the two screws 42 respectively, the two screws 42 are pulled upward or downward away from the end of the mounting part 5 away from the detection unit 8, thereby causing the mounting part 5 to rotate within the positioning sleeve 2, changing the angle of the light emitted by the laser unit relative to the normal of the vehicle body surface to parallel, thus adjusting the angle of the millimeter wave emission. Then, the nuts 43 are tightened at the two screws 42, so that the mounting part 5 is fixed by the restraint of the two nuts 43, and the adjusted detection unit 8 is kept at a fixed angle relative to the vehicle body 1. It is worth mentioning that whether the angle of the light emitted by the laser unit relative to the normal of the vehicle body surface is parallel can be observed with the naked eye. Slight angular deviations will not affect the detection unit's detection of obstacles in front of the vehicle body.

[0048] In addition, after adjusting the angle of the mounting piece 5 by rotating the nut 43, another nut 43 can be additionally screwed on each of the two screw rods 42, and the two nuts 43 on the same screw rod 42 are screwed to fasten each other, so that the nut 43 is fixed relative to the screw rod 42, thereby preventing the two screw rods 42 from moving into the positioning sleeve 2, and further preventing the positioning sleeve 2 and the detection unit 8 in the positioning sleeve 2 from being fixed. Thus, the utility model can adjust the angle of the millimeter wave radar, so that the installed detection device can accurately detect the obstacle in front of the vehicle body 1.

[0049] The above is only a specific embodiment of the utility model, but the design concept of the utility model is not limited to this, and any non-substantial change of the utility model by using the concept should belong to the act of infringing the protection range of the utility model.
