Description
Technical Field
[0001] This application relates to the technical field of radar installation, and particularly to an adjustable radar mechanical structure. Background Art
[0002] In the current era of intelligent driving, the application of radars is gradually increasing. The previous solution of arranging radars through openings is no longer widely used, and a hidden structure design must be adopted. For a non-opening hidden obstacle avoidance radar, the outer body of the radar is directly bonded to the back of the vehicle body covering part by 3M tape 2, and the probe is in close contact with the covering part, as Figure 1 shown.
[0003] It is required that the radar probe must be in close contact with the vehicle body covering part. In fact, the covering part is not a flat plane, and there is still a gap between the probe and the sheet metal, which affects the effective transmission of mechanical waves, resulting in large signal attenuation. Moreover, the bonding cannot effectively form a pre-tightening pressure on the radar, so that the radar always maintains a zero-fitting state with the vehicle body covering part. Therefore, how to solve the problem of radar wave transmission defects existing in the hidden obstacle avoidance radar has become a problem that technicians need to consider and must solve.

Detailed implementation manners
[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are some, rather than all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.
[0033] With the rapid development of intelligent driving technology, radar applications are becoming more and more common. The previous open-hole radar layout method is no longer applicable, and a hidden structure design must be adopted. The installation of existing concealed obstacle avoidance radars requires the probe 13 to be in close contact with the body covering. However, not all body coverings are flat planes. Therefore, gaps are likely to occur between the probe 13 and the covering, affecting the effective transmission of radar mechanics, resulting in relatively large signal attenuation. Moreover, the existing adhesive connection method cannot form a pre-tightening pressure on the radar, making the radar and the body covering always in a zero-fitting state.
[0034] Before presenting the technical solution of this application, the following is a brief introduction to the structure of the radar:
[0035] The bottom end of the radar body 11 is the probe 13, and a scanning head 14 is provided on the outer side of the radar body 11. This application aims to solve the technical problem that the probe 13 and the non-flat body covering cannot always maintain a zero-fitting state.
[0036] In view of this, please refer to Figure 2-3 , a adjustable radar mechanical structure provided by this application includes a radar mechanism, an adjustment mechanism, and a bracket mechanism. The radar mechanism includes a radar body 11 and a pair of lugs 12 protruding from the radar body 11. The adjustment mechanism includes a housing 21, a pair of sliding grooves 23 opened on the housing 21, a pair of pre-tightening bolts 31, and a pair of springs 32 sleeved outside one of the pre-tightening bolts 31 correspondingly. The pair of lugs 12 are slidably arranged in the corresponding sliding grooves 23. The bracket mechanism includes a mounting bracket 41 and two pre-tightening bolt holes opened on the mounting bracket 41. The housing 21 is detachably installed on the mounting bracket 41, and the mounting bracket 41 is used for being mounted on the pre-installed outer covering of the radar. Among them, the pair of pre-tightening bolts 31 respectively pass through one of the lugs 12 and one sliding groove 23 and are adjusted and fastened to one of the pre-tightening bolt holes, and the two springs 32 are both abutted between the bottom surface of the corresponding lug 12 and the top surface of the mounting bracket 41.
[0037] An embodiment of this application provides an adjustable radar mechanical structure. Since the radar body 11 is pre-tightened and installed on the mounting bracket 41 through a pair of springs 32, the radar body 11 is adjusted and screwed on the mounting bracket 41 through a pair of pre-tightening bolts 31, and the mounting bracket 41 is mounted on the pre-installed outer covering of the radar. The pre-adjustment interference of the radar body 11 can be carried out at any time according to the characteristics of the product, reducing the recall and replacement problems caused by the quality defects of the springs 32.
[0038] As described above, the characteristics of the product refer to the elasticity of the spring 32, the surface flatness of the covering, etc.
[0039] In a more specific embodiment, a first through-hole 121 is provided on each of a pair of the lugs 12, a pair of second through-holes 25 are provided on the bottom surface of the housing 21, the heads of two pre-tightening bolts 31 are respectively limited above the first through-holes 121 on the corresponding side, and the screw rods of the two pre-tightening bolts 31 pass through the lugs 12 on the corresponding side and pass through the sliding grooves 23 and the second through-holes 25 and are fastened to the pre-tightening bolt holes on the mounting bracket 41 on the corresponding side.
[0040] In one embodiment, please refer to Figure 4 , a perforation 22 is provided in the middle of the housing 21, the two sliding grooves 23 are located on both sides of the perforation 22, and the probe 13 of the radar body 11 passes through the perforation 22 and is close to the surface of the covering member.
[0041] In one embodiment, the two pre-tightening bolts 31 are both plastic bolts.
[0042] In one embodiment, please refer to Figures 5-7 , the middle of the mounting bracket 41 is suspended, that is, there is a suspended distance from the vehicle body covering member, and the two pre-tightening bolt holes are both provided in the middle of the mounting bracket 41, so as to realize that by adjusting the depth of the pre-tightening bolt 31 screwed into the pre-tightening bolt hole, that is, the length of the pre-tightening bolt 31 screwed into the suspended distance, the probe 13 is closely attached to the vehicle body covering member. A pair of springs 32 are pre-pressed into a pair of sliding grooves 23 of the housing 21 through a pair of lugs 12 of the radar, and a pair of pre-tightening bolts 31 adjust and install the radar body 11 on the mounting bracket 41, ensuring the fidelity and stability of the radar signal transmission.
[0043] In a more specific embodiment, please refer to Figure 3 , the mounting bracket 41 includes a mounting panel 411, a pair of mounting panels 412 and a connecting plate connecting the mounting panel 411 and the two mounting panels 412. The plane of the mounting panel 411 is higher than the plane of the pair of mounting panels 412, so that after the mounting bracket 41 is mounted on the radar pre-mounted outer covering member, there is a suspended distance between the mounting panel 411 and the covering member, providing an adjustment space for the adjustment and screwing of the pre-tightening bolt 31; the pair of mounting panels 412 are used for mounting on the radar pre-mounted outer covering member.
[0044] In a more specific embodiment, the mounting bracket 41 is mounted on the radar pre-mounted outer covering member by welding.
[0045] In a more specific embodiment, the pair of mounting panels 412 of the mounting bracket 41 are both spot-welded to the radar pre-mounted outer covering member, and the fixation is more firm, abandoning the traditional bonding mode and avoiding the instability of bonding.
[0046] In one embodiment, the panel of the mounting bracket 41 at the edge of a pair of the bolt holes 42 is bent inward to form a guiding channel parallel to the axis direction of the holes. The guiding channel guides the screwing-in direction of the pre-tightening bolt 31, ensuring that the axis direction of the pre-tightening bolt 31 is consistent with the axis direction of the corresponding bolt hole 42.
[0047] In a more specific embodiment, an internal thread that is thread-coupled with the screw rod of the pre-tightening bolt 31 is provided on the inner wall surface of the guiding channel.
[0048] In one embodiment, a first guiding structure is provided on the radar body 11, and a second guiding structure is provided on the inner wall surface of the perforation 22 of the housing 21. The extending directions of the first guiding structure and the second guiding structure are both parallel to the axis direction of the pre-tightening bolt 31. The first guiding structure and the second guiding structure cooperate with each other, enabling the radar body 11 to move toward or away from the second through-hole 25 along the axis direction of the second through-hole 25 through the first guiding structure along the second guiding structure, ensuring the consistency and stability of the sliding of the radar body 11. The second guiding structure in the chute 23 of the housing 21 and the first guiding structure on the radar body 11 cooperate with each other to guide the moving direction of the radar body 11. When the radar body 11 is installed in the housing 21, the axis directions of the pre-tightening bolt 31, the first through-hole 121, and the second through-hole 25 are consistent.
[0049] In a more specific embodiment, the first guiding structure is a first strip-shaped groove, and the second guiding structure is a second convex strip. The extending directions of the first strip-shaped groove and the second convex strip are parallel to the axis directions of the first through-hole 121 and the second through-hole 25. The second convex strip slides along the first strip-shaped groove to ensure the consistency and stability of the sliding direction of the radar body 11 along the chute 23 of the housing 21.
[0050] In one embodiment, the first strip-shaped groove is a guiding groove, and the second convex strip is a guide post 24 protruding inside the housing 21.
[0051] In a modified embodiment of the present application, the first guiding structure is a first convex strip, and the second guiding structure is a second strip-shaped groove. The first convex strip slides along the second strip-shaped groove to ensure the consistency and stability of the sliding direction of the radar body 11 along the chute 23 of the housing 21.
[0052] In one embodiment, a first clamping structure is provided on the bottom surface of the housing 21, and a second clamping structure is provided on the mounting panel 411. The first clamping structure and the second clamping structure are in clamping cooperation.
[0053] In one embodiment, the first clamping structure is a card seat 26 protruding from the bottom surface of the housing 21, and the second clamping structure is a bayonet 43 formed on the mounting panel 411. The card seat 26 is in clamping fit with the bayonet 43 to detachably mount the housing 21 on the mounting bracket 41.
[0054] In one embodiment, the radar mechanism further includes a coupling piece provided on the bottom surface of the radar body 11. On the basis that the pre-tightening bolt 31 pre-tightens the radar body 11 close to the vehicle body covering piece, the probe 13 of the radar body 11 and the surface of the vehicle body covering piece are coupled through the coupling piece, avoiding the gap between the non-flat plane and the probe 13. Zero fitting between the probe 13 and the vehicle body covering piece is achieved through the coupling piece, thereby ensuring the effective penetration of the radar mechanical wave and improving the transmission efficiency of the radar wave. The fine adjustment method of adjusting the screwing depth of a pair of pre-tightening bolts 31 into the corresponding bolt holes 42 ensures that the probe 13 of the radar body 11 will not affect the fitting degree between the probe 13 and the outer covering piece due to the adhesive durability failure or the elastic failure of the spring 32.
[0055] In a more specific embodiment, the coupling piece is a silica gel sheet, effectively improving the fitting degree between the covering piece surface of the non-flat plane, such as a curved surface, and the probe 13.
[0056] In one embodiment, each of the pair of chutes 23 is a semi-open slideway structure, ensuring stable up and down adjustment of the radar.
[0057] In one embodiment, a notch is formed on the side surface of the housing 21, and the notch is matched with the scanning head 14.
[0058] The usage method of the embodiment of the present application is as follows:
[0059] Step 1:
[0060] Weld the mounting bracket 41 to the outer covering piece by means of single-sided spot welding;
[0061] Step 2:
[0062] Pre-assemble the two springs 32 in the chutes 23 of the housing 21 respectively, and at the same time ensure that the guiding groove of the radar body 11 is matched with the guide posts 24 on the chute walls of the chutes 23 of the housing 21;
[0063] Step 3:
[0064] Pass two pre-tightening bolts 31 through the first through-holes 121 of the two lugs 12 of the radar body 11 respectively. The two lugs 12 of the radar body 11 pre-compress the spring 32 in the housing 21, and at the same time ensure that neither of the two pre-tightening bolts 31 protrudes from the bottom surface of the housing 21, so as to ensure that the housing 21 can be smoothly snapped onto the mounting bracket 41 after the housing 21 is installed with the radar body 11. Among them, the spring 32 plays an effective control role in pre-compressing the radar body 11 into the housing 21. In the absence of the spring 32, under the action of gravity, the two pre-tightening bolts 31 and the radar body 11 cause the pre-tightening bolts 31 to protrude from the bottom surface of the housing 21, and the protruding screw rods form an interference, which is not convenient for the overall snap-on installation of the housing 21 pre-compressing the radar body 11 on the top surface of the mounting bracket 41.
[0065] Step 4:
[0066] Snap the housing 21 equipped with the radar body 11 onto the card interface of the direct body through the three card seats 26 on its bottom surface, and adjust the depth of the two pre-tightening bolts 31 screwed into the corresponding bolt holes 42, so that the coupling piece attached to the probe 13 of the radar body 11 is closely attached to the surface of the outer covering.
