[0049] The following details the specific implementation manners of the present disclosure with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for the purpose of illustration and explanation of the present disclosure, and are not intended to limit the present disclosure.

[0050] The existing radar antenna is separately designed from the mounting base and connected by a flange. The radar chip is mounted on the mounting base, and the outside of the radar antenna is fixedly connected to a horizontal rotation bracket or a pitching rotation bracket through a fixing member, thereby driving mechanical movement through a horizontal rotation shaft or a vertical rotation shaft. In addition, the cables on the radar chip are also installed and fixed through special fixing components. As the horizontal rotation or pitching rotation occurs, the cables rotate accordingly. After long-term rotation, the cables will be bent or damaged, and the service life will be greatly reduced.

[0051] The present utility model provides an integrated injection-molded antenna for a 3D radar, as Figure 1As shown in the figure, it includes an antenna housing 1 and a mounting base 2, and the antenna housing 1 and the mounting base 2 are integrally injection-molded; a radar chip is provided at one end of the mounting base 2 away from the antenna housing 1.

[0052] An opening is provided at one end of the above-mentioned antenna housing 1 away from the mounting base 2, and a lens 7 is installed at the opening to form a lens antenna. Among them, the antenna in the present invention can be a horn antenna.

[0053] As Figures 1-3 shown, a lens mounting hole 111 is provided at the opening end of the antenna housing 1 in the opening extension direction, and the lens 7 can be fixedly installed on the antenna housing 1 through this mounting hole 111; or a positioning hole 112 is provided at the opening end of the antenna housing 1 extending in the radial direction, and the lens 7 can also be fixedly installed on the antenna housing 1 through this positioning hole 112.

[0054] Since the radar antenna needs to emit microwave signals at multiple angles in two dimensions in the horizontal direction or the pitch direction to perform three-dimensional detection, specifically, the radar antenna needs to be driven to rotate by a horizontal rotation structure or a pitch rotation structure. To facilitate the installation and fixation and rotational movement of the radar antenna, the antenna housing 1 of the present invention includes a left rotation shaft 3 and a right rotation shaft 4. The left rotation shaft 3 and the right rotation shaft 4 are on the same straight line and are used for installation on an external fixed bracket 5. The left rotation shaft 3 and the right rotation shaft 4 are integrally integrated on the antenna housing 1.

[0055] As Figure 2 、 3 shown, taking 3D scanning as an example, the radar antenna needs to be installed on a pitch movement structure, and at the same time the pitch movement structure is installed on a horizontal movement structure (not shown). Then, the left rotation shaft 3 and the right rotation shaft 4 provided on the antenna housing 1 of the present invention together constitute the horizontal rotation shaft of the pitch movement structure. The antenna housing 1 is directly installed on the pitch movement bracket (fixed bracket 5) of the pitch movement structure through the left rotation shaft 3 and the right rotation shaft 4 without other fixing parts and the like. Then, driven by a driving motor, the radar antenna rotates in the pitch direction, and then the pitch movement structure rotates synchronously mechanically in the horizontal direction driven by the horizontal movement structure, thereby realizing multi-angle scanning of the radar antenna in two dimensions of horizontal and pitch. Among them, the horizontal movement structure and the pitch movement structure can realize synchronous rotation through the rotation of a synchronous pulley.

[0056] In the present invention, by integrating the antenna housing 1, the mounting base 2, and the rotation shafts 3 and 4 into one body, the antenna structure is simplified. There is no need for additional fixing parts to fix the antenna to the pitch movement structure or the horizontal movement structure. Only the rotation shafts 3 and 4 integrated on the antenna housing 1 are required to realize connection and synchronous rotation with the external drive shaft 51.

[0057] In order to facilitate the rotation of the left rotation shaft 3 and the right rotation shaft 4 provided on the antenna housing 1 in the pitching direction, it is necessary to drive the pitching motion structure (left rotation shaft 3 and right rotation shaft 4) to move in the pitching direction under the drive of the drive motor, and then the pitching motion structure is synchronously mechanically rotated in the horizontal direction under the drive of the horizontal motion structure. For this purpose, it is necessary to fixedly connect the left rotation shaft 3 and the right rotation shaft 4 with the external drive shaft 51. Specifically, a positioning portion 41 may be provided at one end of the left rotation shaft 3 or the right rotation shaft 4 away from the antenna housing 1. As Figure 1 、 6 、7 shows, a positioning portion 41 is provided on the right rotation shaft 4, and the fixed connection and synchronous rotation with the drive shaft 51 are achieved through the positioning portion 41. The drive shaft 51 is driven to rotate by a drive motor, thereby driving the left rotation shaft 3 and the right rotation shaft 4 to be able to rotate in the pitching direction.

[0058] Furthermore, as Figure 2 and 3 shows, the drive shaft 51 can be used as a driven wheel, the drive motor drives the driving wheel to rotate, and the driving wheel and the driven wheel (drive shaft 51) are used as synchronous wheels to achieve synchronous rotation through a belt. The antenna housing 1, the mounting base 2, the left rotation shaft 3, and the right rotation shaft 4 are integrated into one body. The left rotation shaft 3 and the right rotation shaft 4 form a horizontal rotation shaft, and the horizontal rotation shaft is fixed on the external fixed bracket 5. The external fixed bracket 5 then rotates horizontally around the vertical rotation shaft (horizontal motion structure) through another drive motor. Specifically, the external fixed bracket 5 can be fixedly connected (such as threaded connection) with the horizontal support frame, the horizontal support frame is fixedly connected with the vertical rotation shaft, and the horizontal support frame drives the fixed bracket to rotate horizontally under the drive of the vertical rotation shaft, thereby driving the radar antenna to rotate in the horizontal direction. At the same time, the radar antenna rotates in the pitching direction under the drive of the drive shaft 51.

[0059] Furthermore, the positioning portion 41 can be a positioning protrusion, a positioning groove (not shown) is provided on the drive shaft 51, the positioning protrusion matches the positioning groove, and the left rotation shaft 3 or the right rotation shaft 4 is fixedly connected with the drive shaft 51 by snapping the positioning protrusion into the positioning groove, thereby realizing the synchronous rotation of the two.

[0060] Figure 5 This is the right view of an integrated injection-molded antenna for a 3D radar provided by the present utility model. As Figure 5As shown, a threaded hole 42 can be provided inside the center of one end of the right rotation shaft 4. The threaded hole 42 can be made of metal. Through the setting of the threaded hole 42, on the basis that the positioning protrusion matches the positioning groove, the right rotation shaft 4 can be further fixedly connected to the drive shaft 51, realizing the secondary fixed connection between the drive shaft 51 and the right rotation shaft 4. Moreover, using a metal threaded hole 42 is more durable and can also extend the service life of the right rotation shaft 4.

[0061] In the present utility model, the right rotation shaft 4 or the left rotation shaft 3 is designed as a hollow structure for passing through a cable. Specifically, the cable passes through the slip ring and enters the hollow structure through one end of the right rotation shaft 4 or the left rotation shaft 3 away from the antenna housing 1, and exits through a through hole 31 provided on the side surface of one end of the right rotation shaft 4 or the left rotation shaft 3 close to the antenna housing 1. Among them, the slip ring is fixedly installed at one end of the right rotation shaft 4 or the left rotation shaft 3 away from the antenna housing 1 and rotates synchronously with the right rotation shaft 4 or the left rotation shaft 3.

[0062] As Figure 1 、 4 As shown, the left rotation shaft 3 in the present utility model is designed as a hollow structure for passing through a cable. Specifically, the cable passes through the slip ring and enters the hollow structure through one end of the left rotation shaft 3 away from the antenna housing 1, and exits through a through hole 31 provided on the side surface of one end of the left rotation shaft 3 close to the antenna housing 1.

[0063] As Figure 1 As shown, the present utility model passes the cable through the hollow structure of the rotation shaft and then exits through the through hole 31 provided on the side surface of the rotation shaft, thereby enabling the cable to rotate synchronously with the rotation shaft, and thus greatly reducing the damage such as bending of the cable caused by rotation.

[0064] In a further embodiment of the present utility model, as Figures 1-4 shown, a photoelectric switch limit flap 13 is provided on the outer side of the antenna housing 1, and a photoelectric switch corresponding to the photoelectric switch limit flap 13 is provided on the fixed bracket. Since the radar antenna rotates within a certain angle range, in order to determine whether it moves to a fixed angle position, a photoelectric switch can be set to detect whether the radar antenna moves to a fixed angle position (the maximum angle or the minimum angle position).

[0065] As Figure 4 、 5As shown, the left rotating shaft 3 on the antenna housing 1 is arranged as a hollow structure. At one end of the right rotating shaft 4 on the antenna housing 1 away from the antenna housing 1, a positioning protrusion is provided, and a metal threaded hole 42 is provided at the center of the end face. The photoelectric switch limit flap 13 is arranged directly above the left rotating shaft 3 and can rotate with the rotation of the antenna housing 1. At the same time, a photoelectric switch is arranged at a preset position on the fixed bracket 5. The combination of the photoelectric switch and the photoelectric switch limit flap 13 is used to judge and limit the rotation of the radar antenna within a preset angle range.

[0066] In another embodiment of the present invention, as Figure 1 , 2 shown, a first mounting hole 14 can be provided on the antenna housing 1, and the first mounting hole 14 is used for mounting a laser ranging module. Through the setting of the first mounting hole 14, two signals, namely a microwave signal and a laser signal, can be integrated on the antenna housing 1 at the same time. The combination of the microwave signal and the laser signal can make the radar measurement data more accurate. In specific applications, whether two signal sources are set at the same time can be determined according to requirements.

[0067] In another embodiment of the present invention, a second mounting hole 15 can be provided on one of the antenna housing 1, the left rotating shaft 3 or the right rotating shaft 4, and the second mounting hole 15 is used for mounting an angle sensor. Through the setting of the angle sensor, the specific angle value of the rotation of the radar antenna can be detected, and then the rotation position of the radar antenna can be understood.

[0068] In another embodiment of the present invention, a third mounting hole 16 can be provided on one of the antenna housing 1, the left rotating shaft 3 or the right rotating shaft 4, and the third mounting hole 16 is used for mounting an optical encoder disk. Through the setting of the optical encoder disk, the specific angle value of the rotation of the radar antenna can be detected, and then the rotation position of the radar antenna can be understood.

[0069] If the second mounting hole 15 or the third mounting hole 16 is provided on the left rotating shaft 3 or the right rotating shaft 4, then a mounting plate needs to be provided on the left rotating shaft 3 or the right rotating shaft 4, and then the second mounting hole 15 or the third mounting hole 16 is provided on the mounting plate. As Figure 4 shown, the second mounting hole 15 is provided on the antenna housing 1, and the third mounting hole 16 is provided on the mounting plate of the left rotating shaft 3.

[0070] It should be noted that only one of the angle sensor or the optical encoder disk can be provided, as long as it can detect the specific angle value of the rotation of the radar antenna to judge the rotation position of the radar antenna.

[0071] In a further embodiment of the present invention, as Figure 1 , 3, as shown in FIGS. 7, at least one wire groove 17 is provided on the antenna housing 1, and the wire groove 17 is used to guide the cables provided on electrical components such as radar chips, laser ranging modules, or driving devices to pass through. In order to facilitate the smooth passing of the cables, the wire groove 17 can be designed as a U-shaped structure, and the wire groove 17 of the U-shaped structure is designed with a smooth curved surface.

[0072] As Figures 1-3 shown, on one side of the mounting base 2 above where it is connected to the antenna housing 1, a cable limiting member 22 is provided. The cable limiting member 22 is used to limit the cable to be arranged inside the cavity structure formed between the cable limiting member 22 and the mounting base 2, and inside the cavity structure, a cable limiting flap 23 is provided, which is used to limit the cable to be arranged on one side inside the cavity structure, so that it does not move or shake, and thus the service life of the cable can be extended.

[0073] As Figures 1-5 shown, a plurality of columnar protrusions 18 can be provided on the outer housing of the antenna housing 1, and a support plate 19 is provided between the columnar protrusions 18. This support plate 19 can also be used as a reinforcing rib. Preferably, 4 columnar protrusions 18 are provided. As Figures 1-3 shown, the 4 columnar protrusions 18 enclose a cavity structure. A U-shaped groove is formed between 2 of the columnar protrusions 18, and a U-shaped groove is also formed between the other 2 columnar protrusions 18. The two U-shaped grooves are on a straight line. Of course, only 2 columnar protrusions 18 can also be provided to form a U-shaped groove to guide the cable to pass through. However, compared with 1 U-shaped groove, 2 U-shaped grooves can provide a larger support area for the cable. With the fixed support of the cable, the service life of the cable can be extended.

[0074] A groove 21 is provided inside the mounting base 2, and a reinforcing rib 6 is provided inside the groove 21. By providing the reinforcing rib 6, the effect of enhancing the strength of the mounting base 2 while reducing the weight of the mounting base 2 can be achieved.

[0075] Since the antenna housing 1, the mounting base 2, and the rotating shafts 3 and 4 in the present utility model are all integrally injection-molded, and the antenna housing 1, the mounting base 2, and the rotating shafts 3 and 4 all adopt a pp + glass fiber material. Therefore, at least one of the left rotating shaft 3, the right rotating shaft 4, the antenna housing 1, and the groove 21 inside the mounting base 2 can be provided with a reinforcing rib 6. By providing the reinforcing rib 6 at different positions in the groove 21 of the antenna housing 1 and the mounting base 2 or on the rotating shafts 3 and 4, the strength of the integrally injection-molded antenna structure can be enhanced, so that the integrally injection-molded antenna of the present utility model is light in weight, low in cost, high in strength, simple in structure, easy to install, and high in integration.

[0076] In a further embodiment of the present utility model, a first through hole 211 is provided inside the mounting base 2 (as Figure 7As shown, a second through-hole 12 is provided at the center of the antenna housing 1 (as Figure 6 shown). The centers of the first through-hole 211, the second through-hole 12, and the center of the lens antenna are on the same straight line and are aligned with the signal source of the radar chip.
