In addition, the three-dimensional dimensions of length, width and depth should be included in the actual fabrication.
Further, reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one implementation of the invention. The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.
Examples
Referring to fig. 1 to 7, the present embodiment provides a millimeter wave radar transceiver module, which includes a transceiver unit 100, a support unit 200, and an adjustment unit 300, wherein the transceiver unit 100 has a function of transceiving a millimeter wave signal of a radar, the support unit 200 serves as a placement platform of the whole transceiver unit 100, and the adjustment unit 300 is used for adjusting a pitch angle of the transceiver unit 100.
Specifically, the transceiver unit 100 includes a radar 101, a first hinge base 102 located at one end of the radar 101, and rotating bosses 103 located at two sides of the radar 101; when the radar 101 is standing up, the first hinge base 102 is positioned on the bottom surface of the radar 101; the supporting unit 200 comprises a supporting seat 201 and a second hinged seat 202 positioned at one end of the supporting seat 201, wherein the second hinged seat 202 is hinged to the first hinged seat 102, so that the transceiver unit 100 can rotate by taking the second hinged seat 202 as a circle center, and the supporting seat 201 is provided with a rotating column 203; the adjusting unit 300 comprises an adjusting piece 301 and a ratchet bar 302 penetrating through the adjusting piece 301, the adjusting piece 301 is rotatably connected with the rotating boss 103, namely, the adjusting piece 301 can only rotate around the rotating boss 103, and one end of the ratchet bar 302 is hinged with the rotating column 203.
Further, the adjusting member 301 is provided with a through hole 301a, the ratchet bar 302 penetrates through the through hole 301a, the ratchet bar 302 can slide in the through hole 301a, wherein the adjusting member 301 is provided with a sliding groove 301b along a direction perpendicular to the direction of the through hole 301a, and the sliding groove 301b is provided with a plug 303. When one end of the latch 303 is inserted into the tooth groove of the ratchet bar 302, the transceiver unit 100 is restricted from rotating in the horizontal direction.
Further, a rotary cover 304 is connected to an opening of the sliding groove 301b, and a first spring 305 is disposed between the rotary cover 304 and the plug 303. The elastic force of the first spring 305 makes one end of the latch 303 inserted into the tooth slot, and when the angle between the transceiver unit 100 and the horizontal plane is adjusted to be larger, the transceiver unit 100 is directly operated to rotate, because the latch 303 slides along the ratchet surface of the ratchet bar 302 to the next ratchet and the transceiver unit 100 is restricted from falling back.
It should be noted that the profile of the end of the latch 303 near the ratchet bar 302 is consistent with the tooth space profile of the ratchet bar 302, and the purpose is to enable the latch 303 to slide along the inclined tooth surface of the ratchet bar 302.
Preferably, the inner side of the sliding groove 301b is provided with a limiting groove 301c, the limiting groove 301c is divided into a chute 301c-1 and a straight groove 301c-2, the chute 301c-1 is connected with the straight groove 301c-2, wherein a limiting step 301d is formed at the connection position of the chute 301c-1 and the straight groove 301c-2, namely, the depth of the chute 301c-1 from the through hole 301a to the limiting step 301d is smoothly reduced to 0, and the chute 301c-1 is not excessively and directly connected with the straight groove 301 c-2; the side of the bolt 303 is provided with a limit hole 303a, a second spring 306 is arranged in the limit hole 303a, the second spring 306 is connected with a limit pin 307, and one end of the limit pin 307 is embedded in the limit groove 301 c. Thus, when the latch 303 passes over each ratchet tooth on the ratchet bar 302, the displacement of the latch 303 is smaller than the length of the inclined groove 301c-1, preventing one end of the stopper pin 307 from passing over the stopper step 301d into the straight groove 301 c-2.
Further, the ratchet bar 302 is divided into a first end 302a and a second end 302b, the ratchet teeth are distributed between the first end 302a and the second end 302b, wherein the first end 302a is one end hinged to the rotation column 203, the second end 302b forms a bevel protrusion 302c at the end of the ratchet teeth, the height of the bevel protrusion 302c is significantly higher than that of the rest of the ratchet bar 302, and the bevel protrusion 302c is in transition with the ratchet bar 302 through a bevel;
correspondingly, the through hole 301a is provided with a groove 301e at a position corresponding to the inclined projection 302c, and the inclined projection 302c can be inserted into the groove 301e to contact with the end of the plug 303. Thus, when the pitch angle of the transceiver unit 100 is the largest angle with the horizontal plane, the adjusting element 301 is located near the end of the second end 302b, and the angle with the horizontal plane is further enlarged, which is equivalent to that the adjusting element 301 is further moved along the ratchet bar 302, so that the inclined protrusion 302c can be inserted into the groove 301e and the inclined surface of the inclined protrusion 302c contacts with the end of the bolt 303 and presses the bolt 303 to move away from the ratchet bar 302, and when the bolt 303 moves, the limiting pin 307 passes through the limiting step 301d along the inclined groove 301c-1 and enters the straight groove 301c-2, because the existence of the limiting step 301d limits the resetting of the bolt 303, the whole of the bolt 303 is located in the sliding groove 301b, at this time, the bolt 303 no longer contacts with the ratchet bar 302, the adjusting element 301 is no longer limited, and then the transceiver unit 100 can be reset, i.e., the transceiver unit 100 is retracted to a position where it is attached to the supporting unit 200.
Further, when the transceiver unit 100 returns to the horizontal position, the adjusting member 301 is located near the first end 302a, because the whole of the plug 303 is located in the sliding groove 301b, the pitch angle of the transceiver unit 100 can no longer be fixed, and thus the limiting groove 301c is provided with a reset groove 301f penetrating through the adjusting member 301 toward the first end 302a at the position of the limiting step 301 d.
The first end 302a is fixedly connected with a reset piece 308, the connection mode can be bolt connection or welding, the reset piece 308 is provided with a reset piece 308a, the end portion of the reset piece 308a is provided with a reset fork 308b, namely, the end portion of the reset piece 308a is divided into two branches, wherein the end portion of the reset fork 308b is triangular and forms a reset surface 308c, the reset surface 308c is an inclined surface, and when the reset piece 308a is embedded into the reset groove 301f, the reset surface 308c is tangent to the tail end of the limit pin 307. Therefore, since the reset surface 308c is an inclined surface, it presses the stopper pin 307 to retract into the stopper hole 303a, and at this time, the plug pin 303 is no longer stopped by the stopper pin 307, and under the elastic force of the first spring 305, it is ejected out of the sliding groove 301b and is embedded into the tooth groove of the corresponding ratchet bar 302, so that the next pitch angle adjustment can be performed.
It should be noted that the adjustment unit 300 is provided on both sides of the radar 101 to prevent uneven force on one side. And the point of the ratchet 302 is biased toward the second end 302b to allow the pin 303 to move from the first end 302a to the second end 302 b.
Preferably, the cross section of the ratchet bar 302 and the cross section of the through hole 301a are both rectangular, and the ratchet bar 302 cannot be shifted in the through hole 301a along the direction perpendicular to the ratchet bar 302.
The specific implementation and principle of the embodiment are as follows: in an initial state, the invention is stored, namely the transceiver unit 100 is attached to the supporting unit 200, the transceiver unit 100 is parallel to a horizontal plane, when a radar is needed, the radar 101 is directly lifted according to the need and the angle is adjusted to enable one end of the bolt 303 to be embedded into the tooth groove of the ratchet bar 302 to keep a constant pitching angle; when the device needs to be stored, the pitch angle of the wire-adjusting transceiver unit 100 is the largest angle with the horizontal plane, that is, the adjusting piece 301 is located near the end of the second end 302b, and when the angle with the horizontal plane is continuously enlarged, it is equivalent to that the adjusting piece 301 continuously moves along the ratchet bar 302, so the inclined plane protrusion 302c can be inserted into the groove 301e, the inclined plane of the inclined plane protrusion 302c contacts with the end of the bolt 303 and presses the bolt 303 to move away from the ratchet bar 302, and when the bolt 303 moves, the limiting pin 307 goes over the limiting step 301d along the inclined groove 301c-1 to enter the straight groove 301c-2, because the existence of the limiting step 301d limits the resetting of the bolt 303, the whole body of the bolt 303 is located in the sliding groove 301b, at this time, the bolt 303 no longer contacts with the ratchet bar 302, the adjusting piece 301 is no longer limited, so that the transceiver unit 100 can be reset, that is, the transceiver unit 100 is retracted to the position where the transceiver unit 200 is attached, at this time, because the reset surface 308c is an inclined surface, the pin 307 is pressed to retract into the limiting hole 303a, at this time, the pin 303 is no longer limited by the pin 307, and under the elastic force of the first spring 305, the pin is ejected out of the sliding groove 301b and is embedded into the tooth groove of the corresponding ratchet bar 302, so that the next pitch angle can be adjusted.
