Detailed Implementation

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] This utility model embodiment provides a millimeter-wave radar bracket, see [link / reference] Figure 1 and combined Figures 2 to 9 , Figure 1 This is a structural schematic diagram of a millimeter-wave radar bracket, which includes: a fixing frame 1, a base 2, and a support frame 3;

[0047] The base 2 is horizontally rotatable and mounted on top of the support frame 3;

[0048] The mounting bracket 1 is provided with a first mounting ear 11 and a second mounting ear 12 that are detachably connected to the base 2, wherein the first mounting ear 11 and the second mounting ear 12 are respectively located on adjacent sides of the mounting bracket 1;

[0049] The mounting bracket 1 is located on the top of the horizontal rotating platform 6. The mounting bracket 1 is provided with a first fixing plate 13 and a second fixing plate 14 for fixing the millimeter-wave radar 9 on both sides.

[0050] It should be noted that the millimeter-wave radar bracket of this application is mainly used for the rectangular structure millimeter-wave radar 9. Therefore, this application provides a first fixing plate 13 and a second fixing plate 14 on the fixing frame 1 for fixing the millimeter-wave radar 9 on both sides, which can fix the millimeter-wave radar 9.

[0051] It should also be noted that the base 2 of this application cannot be simultaneously connected to the first mounting ear 11 and the second mounting ear 12. When the first mounting ear 11 is connected to the base 2, the second mounting ear 12 is in an idle state, and when the second mounting ear 12 is connected to the base 2, the first mounting ear 11 is in an idle state. Therefore, when the first mounting ear 11 is connected to the base 2, the millimeter-wave radar 9 needs to rotate 90° within the same plane (e.g., Figure 2 Change to Figure 7 Simply rotate the fixing bracket 1 to connect the base 2 with the second mounting ear 12.

[0052] In this embodiment of the invention, the base 2 is horizontally rotatable and mounted on the top of the support frame 3. The fixing frame 1 is provided with a first mounting ear 11 and a second mounting ear 12 detachably connected to the base 2, with the first mounting ear 11 and the second mounting ear 12 respectively located on adjacent sides of the fixing frame 1. The fixing frame 1 is mounted on the top of the horizontal rotating platform 6, and a first fixing plate 13 and a second fixing plate 14 are provided on the fixing frame 1 to fix the millimeter-wave radar 9 on both sides. With the millimeter-wave radar bracket disclosed above, since the base 2 of this application is horizontally rotatable and mounted on the top of the support frame 3, and since the fixing frame 1 is provided with a first mounting ear 11 and a second mounting ear 12 detachably connected to the base 2, fixing the millimeter-wave radar 9 with the fixing frame 1 can achieve not only rotation in the horizontal plane but also rotation in the horizontal direction.

[0053] Specifically, the base 2 includes: a base plate 21 and multiple fixing rods 22;

[0054] The base plate 21 is rotatably mounted on the top of the support frame 3;

[0055] Multiple fixing rods 22 are vertically arranged on the base plate 21 and are arranged along the transverse direction of the base plate 21;

[0056] The top of the fixing rod 22 is connected to the first mounting ear 11 or the second mounting ear 12 of the fixing bracket 1 by the first bolt 4.

[0057] It should be noted that by vertically setting multiple fixing rods 22 on the base plate 21 and setting them horizontally along the base plate 21, and by connecting the top of the fixing rods 22 to the first mounting ear 11 or the second mounting ear 12 with the first bolt 4, the connection strength between the base plate 21 and the first mounting ear 11 or the second mounting ear 12 can be effectively improved, thus preventing the millimeter-wave radar 9 from shaking during calibration testing.

[0058] Specifically, the fixing rod 22 includes: a support rod, a first vertical plate 23, and a second vertical plate 24;

[0059] The first vertical plate 23 and the second vertical plate 24 are symmetrically arranged on the top of the support rod to form a slot 25 for the first mounting ear 11 or the second mounting ear 12 to be inserted.

[0060] Both the first mounting ear 11 and the second mounting ear 12 have multiple first screw holes 121 that are threaded to the first bolt 4 along their length.

[0061] The first vertical plate 23 has a first through hole 231 for the first bolt 4 to pass through.

[0062] It should be noted that the first vertical plate 23 and the second vertical plate 24 are symmetrically arranged on the top of the support rod to form a slot 25 for the first mounting ear 11 or the second mounting ear 12 to be inserted. The first mounting ear 11 and the second mounting ear 12 are provided with a plurality of first screw holes 121 that are threaded to the first bolt 4 in the length direction. The first vertical plate 23 is provided with a first through hole 231 for the first bolt 4 to pass through, and the first through hole 231 is coaxial with the first screw hole 121. After the first mounting ear 11 or the second mounting ear 12 is inserted into the slot 25, the first bolt 4 is threaded through the first through hole 231 and connected to the first bolt hole 121, so as to realize the fixed connection between the fixing frame 1 and the base 2.

[0063] Furthermore, the height of the first vertical plate 23 is higher than the height of the second vertical plate 24.

[0064] It should be noted that by making the height of the first vertical plate 23 higher than that of the second vertical plate 24, the first vertical plate 23 can be located on the front of the millimeter-wave radar 9, and the second vertical plate 24 can be located on the back of the millimeter-wave radar 9. This can reduce the interference of the first vertical plate 23 and the first bolt 4 on the radio frequency signal of the millimeter-wave radar 9, ensure the radar function, and at the same time improve the overall aesthetics of the millimeter-wave radar bracket.

[0065] Preferably, the first screw hole 121 is a blind hole.

[0066] It should be noted that the first screw hole 121 is set as a blind hole, so that the screw hole is not visible on the front of the millimeter-wave radar bracket. Since the front of the millimeter-wave radar is the signal transmitting surface, it can avoid the millimeter-wave radar bracket, the first bolt and other metals being placed on its front to interfere with the millimeter-wave radar signal. At the same time, it can further improve the overall aesthetics of the millimeter-wave radar bracket.

[0067] It should also be noted that the first screw hole 121 can be a blind hole or a through hole. Those skilled in the art can choose according to their needs. However, in this application, the first screw hole 121 is preferably a blind hole.

[0068] Specifically, the inner sides of the first fixing plate 13 and the second fixing plate 14, which are opposite each other, are provided with grooves 15 along the length direction for cooperating with the side of the millimeter-wave radar 9.

[0069] It should be noted that by providing grooves 15 along the length of the inner sides of the first fixing plate 13 and the second fixing plate 14 for engaging with the sides of the millimeter-wave radar 9, when installing the millimeter-wave radar 9, it is only necessary to align the two sides of the millimeter-wave radar 9 with the grooves 15 of the first fixing plate 13 and the second fixing plate 14 respectively, and then push the millimeter-wave radar 9 into the grooves 15 of the first fixing plate 13 and the second fixing plate 14. Through the above solution, not only is the installation difficulty of the millimeter-wave radar 9 reduced, but the fixing strength of the fixing frame 1 to the millimeter-wave radar 9 is also guaranteed.

[0070] It should also be noted that, since the sliding groove 15 of the first fixed plate 13 and the sliding groove 15 of the second fixed plate 14 are the same, the lower side of the millimeter-wave radar 9 can not only be engaged with the sliding groove 15 of the first fixed plate 13, but also with the sliding groove 15 of the second fixed plate 14. Similarly, the upper side of the millimeter-wave radar 9 can be engaged with both the sliding groove 15 of the first fixed plate 13 and the sliding groove 15 of the second fixed plate 14. Therefore, the millimeter-wave radar 9 can achieve 180° rotation within a plane (e.g., ...). Figure 2 Change to Figure 6 ).

[0071] It is worth noting that, since the millimeter-wave radar 9 can rotate 180° in a plane, and the rotating mounting bracket 1 can achieve the millimeter-wave radar 9's required 90° rotation within the same plane, by rotating the millimeter-wave radar 9 and rotating the mounting bracket 1, the millimeter-wave radar 9 can achieve a 270° rotation in a plane (e.g., ...). Figure 2 Change to Figure 8 ).

[0072] Furthermore, the millimeter-wave radar bracket also includes: multiple second bolts 5;

[0073] The slide 15 has a first retaining plate 151 and a second retaining plate 152;

[0074] The first card plate 151 has multiple second through holes 1511 for the passage of the second bolt 5;

[0075] The second plate 152 has a plurality of second screw holes 1521 that are threaded to the second bolt 5 on the side near the first plate 151. The plurality of second screw holes 1521 correspond one-to-one with the plurality of second through holes 1511 and are coaxially arranged.

[0076] It should be noted that by providing multiple second through holes 1511 for the second bolt 5 to pass through in the first card plate 151, and providing multiple second threaded holes 1521 for the second bolt 5 to be threaded together on the side of the second card plate 152 near the first card plate 151, and then providing a third through hole on the side of the millimeter-wave radar 9, the second bolt 5 can sequentially pass through the second through hole 1511, the third through hole and the second threaded hole 1521 for threaded connection, thus preventing the millimeter-wave radar 9 from coming out of the slide groove 15 during calibration testing.

[0077] Preferably, the second screw hole 1521 is a blind hole.

[0078] It should be noted that the second screw hole 1521 is set as a blind hole, so that the screw hole is not visible on the front of the millimeter-wave radar bracket, thus further improving the overall aesthetics of the millimeter-wave radar bracket.

[0079] It should also be noted that the second screw hole 1521 can be a blind hole or a through hole, and those skilled in the art can choose according to their needs. However, in this application, the second screw hole 1521 is preferably a blind hole.

[0080] Specifically, the first fixing plate 13 has a fourth through hole 131 in the direction away from the second fixing plate 14. The fourth through hole 131 is used for the external plug to be connected to the millimeter-wave radar 9.

[0081] It should be noted that by providing a fourth through hole 131 in the direction away from the second fixed plate 14 on the first fixed plate 13, it is convenient for the external plug to pass through the fourth through hole 131 and be plugged into the millimeter-wave radar 9.

[0082] Specifically, the fixed frame 1 is connected to the base 2 via the horizontal rotating platform 6.

[0083] It should be noted that the fixed frame 1 is connected to the base 2 through the horizontal rotating platform 6, which not only ensures the connection strength between the fixed frame 1 and the base 2, but also enables the fixed frame 1 and the base 2 to rotate relative to each other.

[0084] It should also be noted that the horizontal rotary table 6 of this application includes a mounting base, a rotating plate and a rotating shaft, wherein the rotating plate is rotatably mounted on the mounting base via the rotating shaft.

[0085] Specifically, the support frame 3 is a telescopic support frame 3;

[0086] The base 2 is located on top of the support frame 3.

[0087] It should be noted that the support frame 3 is set as a telescopic support frame 3, and the base 2 is set on the top of the support frame 3. Thus, the height of the millimeter-wave radar 9 can be adjusted by telescopically extending and retracting the support frame 3.

[0088] Specifically, the support frame 3 includes: a first telescopic rod 31, a second telescopic rod 32, a third telescopic rod 33 (not shown), and a support base 34;

[0089] The upper ends of the first telescopic rod 31, the second telescopic rod 32, and the third telescopic rod 33 are all rotatably connected to the lower end face of the support base 34.

[0090] It should be noted that the upper ends of the first telescopic rod 31, the second telescopic rod 32, and the third telescopic rod 33 are all rotatably connected to the lower end face of the support base 34. During use, the first telescopic rod 31, the second telescopic rod 32, and the third telescopic rod 33 can be rotated outwards to form a stable tripod. After use, the first telescopic rod 31, the second telescopic rod 32, and the third telescopic rod 33 can be rotated inwards to bring them closer together, thus reducing the overall volume. Therefore, the support frame 3 of this application is not only easy to install, but also has a stable triangular structure during use, and can also greatly facilitate transportation.

[0091] Furthermore, the support frame 3 also includes: a mounting plate 35 and a pitch adjustment mechanism 36;

[0092] Mounting plate 35 is mounted on support base 34 via pitch adjustment mechanism 36, which is used to adjust the tilt angle between mounting plate 35 and support base 34.

[0093] The base 2 is detachably mounted on the mounting plate 35.

[0094] It should be noted that by setting the mounting plate 35 and the pitch adjustment mechanism 36, and by setting the mounting plate 35 on the support base 34 through the pitch adjustment mechanism 36, this application can adjust the tilt angle between the mounting plate 35 and the support base 34 through the pitch adjustment mechanism 36, thereby adjusting the tilt angle of the millimeter-wave radar 9.

[0095] Preferably, the pitch adjustment mechanism 36 of this application can achieve any angle adjustment from 0° to ±50°.

[0096] Furthermore, the millimeter-wave radar bracket also includes: a quick-release plate 7 and multiple third bolts 8;

[0097] The quick-release plate 7 has multiple slotted holes for the third bolt 8 to pass through;

[0098] The quick-release plate 7 is connected to the base 2 and the support frame 3 by the third bolt 8.

[0099] It should be noted that by setting up a quick-release plate 7 and opening multiple oblong holes in the quick-release plate 7 for the third bolt 8 to pass through, the quick-release plate 7 is connected to the base 2 and the support frame 3 through the third bolt 8. This not only enables the base 2 of this application to be quickly installed and connected to the support frame 3 of this application, but also enables the base 2 of this application to be quickly installed and connected to other support components.

[0100] Preferably, the lower part of the horizontal rotary table 6 is provided with a support plate 10 that is connected to the quick-release plate 7.

[0101] It should be noted that the support plate 10 is connected to the support frame 3 by the third bolt 8 passing through the waist-shaped hole, and the support plate 10 is connected to the upper base 2 by bolts.

[0102] Preferably, the base 2, the horizontal rotating table 6, the support plate 10 and the quick-release plate 7 are all fixedly connected by bolts.

[0103] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
