DETAILED DESCRIPTION

[0045] In order to make the above objectives, characteristics and advantages of the present application more apparent, more comprehensible, the specific embodiments of the present application are described in detail below with reference to the drawings. In the following description, a large number of specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, and therefore the present application is not limited to the specific embodiments disclosed below.

[0046] With reference to Figure 1 , Figures 8 to 10 , an embodiment of the present application provides an antenna, which comprises an azimuth angle adjusting mechanism 10. Specifically, the azimuth angle adjusting mechanism 10 comprises a support structure 11, a first connecting piece 12 and a first driving wheel 13. The support structure 11 is provided with a clutch 1101 and a reset piece 1102. The first connecting piece 12 is used to be connected with a power shaft of a motor 20, and the first connecting piece 12 is provided with a first connecting part 121. The first driving wheel 13 is used to drive a reflecting plate 30 to rotate, and the first driving wheel 13 is coaxially arranged with the first connecting piece 12. The first driving wheel 13 is provided with a second connecting part 131 which is abuttingly matched with the first connecting part 121. When the first connecting part 121 rotates, the second connecting part 131 can be driven to move so as to make the first driving wheel 13 move along an axial direction Z from a locking position to an unlocking position. The first driving wheel 13 is also connected with the reset piece 1102, and the reset piece 1102 is used to drive the first driving wheel 13 to move from the unlocking position to the locking position. Wherein, with reference to Figure 12 , when the first driving wheel 13 is located at the unlocking position, the first driving wheel 13 and the clutch 1101 are separated from each other, and the first connecting piece 12 can drive the first driving wheel 13 to rotate. Figure 11 , when the first driving wheel 13 is located at the locking position, the first driving wheel 13 and the clutch 1101 are locked with each other.

[0047] The above-mentioned antenna and the azimuth angle adjusting mechanism 10 thereof. When it is needed to adjust the azimuth angle of the antenna, the motor 20 works, the motor 20 drives the first connecting piece 12 to rotate, the first connecting piece 12 first makes the first driving wheel 13 move along the axial direction Z from the locking position to the unlocking position, and then drives the first driving wheel 13 to rotate to adjust the angular position to a preset angle. When the adjustment of the azimuth angle of the antenna is completed, the reset piece 1102 drives the first driving wheel 13 to move from the unlocking position to the locking position under the action of the reset force of the reset piece 1102, and the first driving wheel 13 and the clutch 1101 are locked with each other, so that the locking of the reflecting plate 30 can be realized, and then the impact force can be prevented from being transmitted to the motor 20 when the reflecting plate 30 is acted by external force, and the damage failure of the motor 20 caused by the external impact force can be effectively avoided.

[0048] In some embodiments, the support structure 11 includes, but is not limited to, various structures such as a housing or a support frame, etc. that can support the first driving wheel 13, which can be flexibly adjusted and arranged according to actual needs.

[0049] Referring to Figures 11 to 15 In some embodiments, the second abutting portion 131 is arranged, for example, at an end of the first driving wheel 13 facing the first abutting member 12, so as to be capable of abutting with the first abutting portion 121 of the first abutting member 12. When the first abutting portion 121 rotates with the first abutting member 12, it can move along the axial direction Z of the first driving wheel 13 from the locking position to the unlocking position.

[0050] Referring to Figures 11 to 15 In one embodiment, the second abutting portion 131 includes a guide wall 1311 arranged around the circumference of the first driving wheel 13, and a first braking surface 1312 connected to an end of the guide wall 1311 close to the first abutting member 12 along the circumferential direction of the first driving wheel 13. The distance S between the guide wall 1311 and the end surface of the first abutting member 12 decreases along the guide direction of the guide wall 1311. Referring to Figure 11 With Figure 13 When the first driving wheel 13 is in the locking position, the first abutting portion 121 corresponds to an end of the guide wall 1311 away from the first abutting member 12 along the circumferential direction of the first driving wheel 13. Referring to Figure 12 , Figure 14 With Figure 15 When the first driving wheel 13 is in the unlocking position, the first abutting portion 121 abuts with the first braking surface 1312. Thus, when the first abutting member 12 rotates to drive the first abutting portion 121 to move from the locking position to the unlocking position, the first abutting portion 121 starts to move from the end of the guide wall 1311 away from the first abutting member 12 along the circumferential direction of the first driving wheel 13, and moves along the guide wall 1311 to the end of the guide wall 1311 close to the first abutting member 12 along the circumferential direction of the first driving wheel 13 to abut with the first braking surface 1312. At the same time, since the first abutting member 12 is fixed in position along the axial direction, the first driving wheel 13 is separated from the clutch 1101 when moving from the locking position to the unlocking position along the axial direction Z, and at the same time, the reset member 1102 is deformed, thereby driving the first driving wheel 13 to rotate.

[0051] Further, when the first adapter 12 drives the first driving wheel 13 to rotate to the preset angle and the reflector 30 is adjusted to the target azimuth angle, the first adapter 12 stops driving the first driving wheel 13. Further, in order to facilitate the reset member 1102 to drive the first driving wheel 13 to move from the unlocking position to the locking position, the first adapter 12 is reversely rotated to move the first adapter portion 121 to the guide wall 1311 away from one end of the first adapter 12 along the circumferential direction of the first driving wheel 13, so that the first adapter portion 121 can avoid the first driving wheel 13 and will not limit the axial reset of the first driving wheel 13. That is, under the reset force of the reset member 1102, the first driving wheel 13 can be smoothly moved from the unlocking position to the locking position, and then the reset member 1102 can use a relatively small reset force to complete the reset of the first driving wheel 13, and the force acting on the motor 20 during the rotation of the first driving wheel 13 is small and will not affect the working performance of the motor 20.

[0052] Of course, in some optional solutions, when the first adapter 12 drives the first driving wheel 13 to rotate to the preset angle and the reflector 30 is adjusted to the target azimuth angle, the first adapter 12 stops driving the first driving wheel 13, and the elastic reset force of the reset member 1102 is large and can drive the first driving wheel 13 to rotate in the reverse direction to move the first driving wheel 13 from the unlocking position to the locking position.

[0053] Please refer to Figure 18 and Figure 19 In some embodiments, the guide wall 1311 can be a spiral wall surface arranged to extend around the first driving wheel 13 in the circumferential direction, and when the first adapter portion 121 moves along the guide wall 1311, the movement of the first adapter portion 121 is relatively smooth, stable, and low noise. Alternatively, the guide wall 1311 can be an arc-shaped wall surface or a straight wall surface arranged to extend around the first driving wheel 13 in the circumferential direction, as long as it can guide the movement of the first adapter portion 121 from one end of the first adapter 12 to the other end of the first adapter 12 along the circumferential direction of the first driving wheel 13.

[0054] It should be noted that when the guide wall 1311 is an arc-shaped wall surface or a straight wall surface, the guide wall 1311 is arranged to be inclined relative to the axial plane of the first driving wheel 13, so that the distance S between the guide wall 1311 and the end surface of the first adapter 12 decreases along the guide direction of the guide wall 1311. The axial plane refers to a plane perpendicular to the axial direction of the first driving wheel 13.

[0055] Please refer to Figure 18 and Figure 19In some embodiments, the first interface portion 121 is provided with a pressing surface 1211 configured to be in abutting contact with the guide wall 1311. In this way, the first interface portion 121 can move along the guide wall 1311 smoothly, stably and quietly due to the surface contact between the first interface portion 121 and the guide wall 1311. In addition, the first interface portion 121 is further provided with a second braking surface 1212 configured to be in abutting contact with the first braking surface 1312. In this way, when the first driving wheel 13 is in the unlocked position, the second braking surface 1212 of the first interface portion 121 is in abutting contact with the first braking surface 1312 of the second interface portion 131, i.e. in surface contact, to drive the first driving wheel 13 to rotate stably.

[0056] Specifically, the pressing surface 1211 can be, for example, an inclined surface or an arc-shaped surface, which is inclined relative to the axial direction of the first driving wheel 13, due to the surface contact between the pressing surface 1211 and the guide wall 1311.

[0057] Specifically, the second braking surface 1212 is connected to the pressing surface 1211, and when the pressing surface 1211 moves along the guide wall 1311 to the end of the guide wall 1311 close to the first interface portion 12 in the circumferential direction of the first driving wheel 13, the second braking surface 1212 is in abutting contact with the first braking surface 1312. The second braking surface 1212 and the first braking surface 1312 are in mutual abutment, and are both, for example, flat surfaces, and are parallel to the axial direction Z of the first driving wheel 13.

[0058] Please refer to Figure 11 , Figure 18 and Figure 19 In one embodiment, the first interface portion 121 is provided with a first arc-shaped wall surface 1213 and a second arc-shaped wall surface 1214 arranged opposite to each other in the radial direction. The second interface portion 131 is provided with a third arc-shaped wall surface 1313 and a fourth arc-shaped wall surface 1314 arranged opposite to each other in the radial direction. The third arc-shaped wall surface 1313 and the first arc-shaped wall surface 1213 are mutually adapted in shape, and the fourth arc-shaped wall surface 1314 and the second arc-shaped wall surface 1214 are mutually adapted in shape. In this way, when the first interface portion 121 drives the first driving wheel 13 to move from the locked position to the unlocked position, the first arc-shaped wall surface 1213 moves along the third arc-shaped wall surface 1313, and the second arc-shaped wall surface 1214 moves along the fourth arc-shaped wall surface 1314, thereby improving the stability of the movement of the first driving wheel 13 in the axial direction Z.

[0059] Please refer to Figure 11 , Figure 18 and Figure 19In one embodiment, the second interface portion 131 is a groove formed on the axial end face of the first driving wheel 13, and the first interface portion 121 extends into the groove through the slot of the groove. The guide wall 1311 extends from the bottom wall of the groove to the side wall of the groove, and the first braking face 1312 is arranged on the side wall of the groove.

[0060] The bottom wall of the groove refers to the position on the inner wall of the groove opposite to the slot.

[0061] In one embodiment, the guide wall 1311 is provided with two, and the first braking face 1312 is provided with two. The two guide walls 1311 are connected to each other at one end away from the first interface piece 12 along the circumferential direction of the first driving wheel 13, and each guide wall 1311 is connected to one first braking face 1312 at one end close to the first interface piece 12 along the circumferential direction of the first driving wheel 13. In this way, the first interface portion 121 can drive the first driving wheel 13 to move from the locked position to the unlocked position along the clockwise rotation, thereby driving the first driving wheel 13 to adjust the azimuth angle of the reflecting plate 30 according to the clockwise rotation. The first interface portion 121 can also drive the first driving wheel 13 to move from the locked position to the unlocked position along the counterclockwise rotation, thereby driving the first driving wheel 13 to adjust the azimuth angle of the reflecting plate 30 according to the counterclockwise rotation. The adjustment of the azimuth angle of the antenna is more flexible, and bidirectional adjustment can be achieved, which is more convenient for operation.

[0062] Specifically, the abutting face 1211 and the second braking face 1212 are each provided with two. Each abutting face 1211 is arranged corresponding to each guide wall 1311, and each second braking face 1212 is arranged corresponding to each first braking face 1312.

[0063] Optionally, the first interface portion 121 further comprises a first transition face 1215 arranged between the two abutting faces 1211. The second interface portion 131 further comprises a second transition face 1315 arranged between the two second braking faces 1212. When the first driving wheel 13 moves to the locked position, the first transition face 1215 and the second transition face 1315 abut each other.

[0064] It should be noted that in some optional schemes, the specific structure of the first interface portion 121 on the first interface piece 12 in the above embodiment can also be arranged on the first driving wheel 13, and the specific structure of the second interface portion 131 on the first driving wheel 13 is correspondingly arranged on the first interface piece 12, which can also drive the first driving wheel 13 to move from the locked position to the unlocked position when the first interface piece 12 rotates. This embodiment will not be described here, but it should be noted that the simple transformation scheme according to the above embodiment belongs to the same inventive concept and should therefore be within the scope of protection of the present application.

[0065] In one embodiment, the first driving wheel 13 is provided with a first positioning shaft 132, the first abutting piece 12 is provided with a first shaft hole 122 corresponding to the first positioning shaft 132, and the first positioning shaft 132 is rotatably arranged in the first shaft hole 122. Alternatively, the first driving wheel 13 is provided with a second shaft hole, the first abutting piece 12 is provided with a second positioning shaft 153 corresponding to the first positioning shaft 132, and the second positioning shaft 153 is rotatably arranged in the second shaft hole. In this way, the first abutting piece 12 is positioned and guided relative to the first driving wheel 13, and the rotation of the first abutting piece 12 relative to the first driving wheel 13 is more stable, and the first driving wheel 13 can stably move along the axial direction Z.

[0066] Referring to Figure 10 , Figures 18 to 21 In some embodiments, the support structure 11 is provided as a housing, for example, and the support structure 11 is formed with a third shaft hole 1103 corresponding to the position of the first abutting piece 12. The first abutting piece 12 can extend into the interior of the housing through the third shaft hole 1103 and abut with the second abutting part 131 of the first driving wheel 13 located in the interior of the housing. In addition, the azimuth adjustment mechanism 10 of the antenna further includes a snap ring 14 which is detachably clamped and fixed to the outer wall of the first abutting piece 12 and abuts with the outer wall of the support structure 11. The snap ring 14 limits the position of the first abutting piece 12 and prevents the first abutting piece 12 from falling into the interior of the housing through the third shaft hole 1103, thereby causing the power shaft of the motor 20 to be separated.

[0067] In some embodiments, the support structure 11 is formed with a fourth shaft hole 1104 corresponding to the position of the first positioning shaft 132, and the first positioning shaft 132 is rotatably arranged in the fourth shaft hole 1104. In this way, the first positioning shaft 132 is rotatably arranged in the support structure 11 and the first abutting piece 12 at opposite ends, respectively, and the first driving wheel 13 is stably and rotatably arranged on the support structure 11.

[0068] In some embodiments, the reset member 1102 includes, but is not limited to, an elastic reset member 1102 such as a spring, an elastic block, an elastic strip, an elastic column, etc., as long as it can provide an elastic reset force to push the first driving wheel 13 from the unlocked position to the locked position.

[0069] In this embodiment, the reset member 1102 is a spring, for example, and the spring is connected between the first driving wheel 13 and the support structure 11 at opposite ends, and can be configured as a compression spring or a tension spring, which can be configured according to actual needs. Specifically, the spring is configured as a compression spring, one end of the spring abuts against the end of the first driving wheel 13 away from the first docking member 12, and the other end of the spring abuts against the bottom of the support structure 11. When the first driving wheel 13 is in the unlocked position, the driving portion is located at the end of the first driving wheel 13 away from the first docking member 12 along the circumferential direction of the first driving wheel 13, that is, the distance between the first driving wheel 13 and the bottom of the support structure 11 is relatively large, and the spring is in an extended state or a slightly compressed state; when the first docking member 12 rotates to move the first driving wheel 13 from the unlocked position to the locked position, the first driving wheel 13 moves toward the bottom of the support structure 11, and the spring is compressed at the same time as the clutch member 1101 is disengaged, so that the spring has a restoring force.

[0070] Please refer to Figure 10 、 Figure 11 、 Figure 20 and Figure 21 In some embodiments, the support structure 11 is provided with a first flange 1105 circumferentially arranged around the fourth shaft hole 1104, one end of the spring is sleeved on the first flange 1105, and the first flange 1105 serves as a positioning function for the spring. In addition, the first positioning shaft 132 also penetrates the first flange 1105, thereby improving the rotation stability of the first driving wheel 13. In addition, a second flange 133 is formed on the end face of the first driving wheel 13 away from the first docking member 12, and the other end of the spring penetrates the recess formed by the second flange 133 and the end face of the first driving wheel 13 to serve as a positioning function for the spring.

[0071] In some embodiments, the first driving wheel 13 includes but is not limited to a gear, a belt pulley, or a sprocket, and the like, which can be selected according to actual needs, and is not limited herein. In this embodiment, the first driving wheel 13 will be specifically taken as a gear as an example for expansion, but is not limited thereto.

[0072] In one specific embodiment, the first driving wheel 13 is specifically configured as a gear. Please refer to Figure 12 、 Figure 14 and Figure 15 When the first driving wheel 13 is in the unlocked position, the toothed portion of the first driving wheel 13 is separated from the clutch member 1101, that is, the rotation of the first driving wheel 13 is not limited by the clutch member 1101, so that the first docking member 12 can drive the first driving wheel 13 to adjust the rotation when the first docking member 12 rotates, thereby achieving adjustment of the azimuth angle of the antenna; please refer to Figure 11 and Figure 13When the first driving wheel 13 is located at the locking position, the clutch 1101 is inserted between any two adjacent tooth portions of the first driving wheel 13, thereby limiting the rotation of the first driving wheel 13 and playing a locking role. When the first abutting member 12 rotates to drive the first driving wheel 13 to move from the locking position to the unlocking position, the first driving wheel 13 moves away from the first abutting member 12, thereby achieving mutual disengagement with the clutch 1101.

[0073] It should be noted that the reflecting plate 30 is connected with a second driving wheel 40 connected with the first driving wheel 13, and the first driving wheel 13 can drive the second driving wheel 40 to rotate, thereby achieving the adjustment of the azimuth angle of the reflecting plate 30. The first driving wheel 13 can be directly connected with the second driving wheel 40 to directly drive the second driving wheel 40 to rotate, or can be indirectly connected with the second driving wheel 40, that is, one or more intermediate transmission wheels 15 are arranged between the first driving wheel 13 and the second driving wheel 40, thereby facilitating the rotation of the reflecting plate 30.

[0074] In an embodiment, the azimuth angle adjustment mechanism 10 of the antenna further comprises an intermediate transmission wheel 15 arranged between the first driving wheel 13 and the reflecting plate 30. The first driving wheel 13 is connected with the intermediate transmission wheel 15, and the intermediate transmission wheel 15 is used to drive the reflecting plate 30 to rotate. The intermediate transmission wheel 15 is specifically, for example, a speed reduction wheel. In this way, the speed reduction wheel plays a role of speed reduction, can stably drive the reflecting plate 30 to rotate and adjust the azimuth angle, and can improve the adjustment accuracy of the azimuth angle.

[0075] When the first driving wheel 13 is a gear, the intermediate transmission wheel 15 is a gear meshing with the first driving wheel 13; when the first driving wheel 13 is a belt pulley or a chain wheel, the intermediate transmission wheel 15 is a belt pulley or a chain wheel arranged correspondingly with the first driving wheel 13. In addition, the speed reduction ratio of the speed reduction wheel includes but is not limited to 1:2-30, which can be flexibly adjusted and arranged according to actual needs.

[0076] Please refer to Figure 10 , Figure 17 and Figure 21 In an embodiment, the intermediate transmission wheel 15 is rotatably arranged on the support structure 11, the intermediate transmission wheel 15 is provided with a stop portion 151, and the support structure 11 is provided with at least one positioning surface 11061 abutting and positioning with the stop portion 151. In this way, when the first driving wheel 13 drives the intermediate transmission wheel 15 to move to a position where the stop portion 151 and the positioning surface 11061 abut and position with each other, the positioning surface 11061 can limit the continuous rotation of the intermediate transmission wheel 15 and the first driving wheel 13, thereby playing a role of positioning and calibration. After completing the zero operation, under the driving of the first abutting member 12, the first driving wheel 13 and the intermediate transmission wheel 15 drive the reflecting plate 30 to rotate in the opposite direction to adjust the azimuth angle, which can improve the adjustment accuracy of the azimuth angle.

[0077] Please refer to Fig Figures 5 to 7 、 Figure 10 、 Figure 17 With Figure 21 In some embodiments, when the stop portion 151 of the intermediate transmission wheel 15 moves to a position in mutual abutment with the positioning surface 11061, the reflecting plate 30 moves to a limit position, for example, left or right rotation, i.e. unable to continue to increase the azimuth angle. Specifically, the positioning surface 11061 is provided with two, for example, the left and right limit positions of the reflecting plate 30 correspond to the left and right limit positions of the reflecting plate 30. When the stop portion 151 rotates, for example, to the left with the intermediate transmission wheel 15 to abut with one of the positioning surfaces 11061, the reflecting plate 30 is adjusted to the left limit position and unable to continue to rotate to the left to increase the azimuth angle. The control device of the antenna can identify the left limit position of the inductive antenna, as shown in Fig Figure 7 ; when the stop portion 151 rotates, for example, to the right with the intermediate transmission wheel 15 to abut with the other positioning surface 11061, the reflecting plate 30 is adjusted to the right limit position and unable to continue to rotate to the right to increase the azimuth angle. The control device of the antenna can identify the right limit position of the inductive antenna, as shown in Fig Figure 6 . In this way, not only left rotation calibration can be achieved, but also right rotation calibration can be achieved.

[0078] In a specific embodiment, the adjustment of the azimuth angle of the antenna includes the following steps:

[0079] The calibration step, the power shaft of the motor 20 drives the first adapter 12 to rotate, for example, in the first direction, i.e. input power to the first adapter 12; the first adapter 12 rotates to drive the first adapter portion 121 to move along the guide wall 1311, at this time the first drive wheel 13 moves away from the first adapter 12 to achieve the gradual separation of the first drive wheel 13 and the clutch 1101, when the second brake surface 1212 of the first adapter portion 121 and the first brake surface 1312 are in mutual abutment, the first drive wheel 13 and the clutch 1101 are separated, i.e. unlocking; the first adapter 12 continues to rotate in the first direction, the first drive wheel 13 drives the intermediate transmission wheel 15 to rotate, the intermediate transmission wheel 15 drives the reflecting plate 30 to rotate in the first direction, when the stop portion 151 of the intermediate transmission wheel 15 abuts with one of the positioning surfaces 11061, the reflecting plate 30 is adjusted to the limit position in the first direction, the control device can sense the position of the antenna and achieve zero calibration;

[0080] The azimuth angle adjusting step, power reverse input, the power rotating shaft of the motor 20 drives the first connecting piece 12 to rotate along the second direction for example, the second direction is opposite to the first direction, the first connecting part 121 of the first connecting piece 12 moves along the guide wall 1311 downhill, at the same time, the first driving wheel 13 resets under the reset force of the reset part 1102 and is locked with the clutch part 1101, which presents a short-term locking. With the continuous power input, the first connecting part 121 of the first connecting piece 12 moves along the guide wall 1311 uphill, at this time, the first driving wheel 13 moves towards the direction away from the first connecting piece 12, to realize the gradual separation of the first driving wheel 13 and the clutch part 1101, when the other second brake surface 1212 of the first connecting part 121 and the other first brake surface 1312 are in mutual abutment, the first driving wheel 13 is separated from the clutch part 1101 again, that is, to realize the unlocking again; the first connecting piece 12 continues to rotate along the second direction, the second driving wheel 40 drives the intermediate transmission wheel 15 to continue to rotate correspondingly, the intermediate transmission wheel 15 drives the reflecting plate 30 to continue to rotate along the second direction, when the reflecting plate 30 rotates to the target azimuth angle, the power stops;

[0081] The locking step, the power is input again in reverse, that is, the power rotating shaft of the motor 20 drives the first connecting piece 12 to rotate along the first direction for example, the first connecting part 121 of the first connecting piece 12 moves along the guide wall 1311, when the second connecting part 131 moves from the unlocking position to the locking position, the power stops, completing the adjusting operation, at the same time, the self-locking of the device is also completed.

The movable groove 1106 is formed with a stop surface at the opposite ends in the movement direction of the stop part 151. The movable groove 1106 not only plays a guiding role to improve the rotation stability of the intermediate transmission wheel 15, but also can realize the azimuth angle calibration function of the reflecting plate 30 due to the formation of the stop surface.

[0083] Please refer to Figure 10 、 Figure 16 and Figure 20 In an embodiment, the intermediate transmission wheel 15 is formed with a sliding groove 152 on the end surface away from the stop part 151, and the support structure 11 is provided with a damping part 16 for abutting and cooperating with the bottom wall of the sliding groove 152.
