Description

Technical Field

[0001] This utility model relates to the sensing device of automatic doors, and in particular to a microwave sensing device whose microwave sensing direction can be freely adjusted. Background Technology

[0002] With advancements in technology, automatic doors have become widely used in various locations, including convenience stores, department stores, offices, and homes. Currently, automatic door systems primarily consist of a motor system, a track / linkage system, a control system, and sensors. When the sensors detect someone passing by or approaching the door, the control system activates the motor and track / linkage systems to automatically open the door, replacing the previous need for manual opening and thus improving pedestrian flow and commuting efficiency. Commonly used sensors include infrared sensors and microwave sensors.

[0003] Existing microwave sensing devices typically work by orienting the microwave sensor in a specific direction, allowing it to emit microwaves in that direction. The distance or direction of movement of an object is calculated by the time difference or intensity difference of the reflected microwaves. Therefore, correctly orienting the microwave sensor significantly impacts the accuracy and range of the sensing. For example, if the microwave sensor is too perpendicular to the ground, a person would need to be very close to an automatic door to be detected, potentially leading to injury from a collision if the door fails to open in time. Conversely, if the microwave sensor is too parallel to the ground, the automatic door might open from a great distance, potentially preventing it from closing due to movement of people in the distance. Therefore, adjusting the orientation of the microwave sensor is crucial. However, while existing microwave sensors have structures for adjusting orientation, they lack positioning capabilities, making them prone to deviation due to accidental activation or impact. Therefore, providing a microwave sensing device that can accurately adjust the sensor's orientation and has a certain limiting function is a pressing issue for industry professionals and researchers in this field.

[0066] The preferred embodiments of this utility model are described below with reference to the accompanying drawings. It should be understood that these drawings and descriptions are for illustrative purposes only and are not intended to limit the scope of this utility model. Furthermore, the terms "upper" and "lower," "left" and "right," "front" and "rear," "first" and "second," etc., used in the specification are used to clearly describe the relative positions between components or mechanisms and are not intended to be limiting.

[0067] Please see Figures 1 to 3As shown, a preferred embodiment of the microwave sensing device provided by this utility model mainly includes a base 10, a top cover 20, and a movable member 30. The base 10 is used to house the movable member 30, a microwave sensor 40, a circuit board 50, and a light source 60. Specifically, the base 10 has a generally circular rotating groove 11, in which the movable member 30 is rotatably disposed. One side of the rotating groove 11 has a planar abutment surface 110. The base 10 also has a first pivot 12, two first limiting blocks 13, 14, and a first engaging portion 15 on the bottom surface of the rotating groove 11. The first pivot 12 is located at the center of the rotating groove 11. The two first limiting blocks 13, 14 are elongated blocks located on opposite sides of the first pivot 12, forming an angle not equal to 0. In other words, the two first limiting blocks 13, 14 are not parallel. The first engaging portion 15 is an arc-shaped, elongated block located on the side of the first pivot 12 opposite to the abutment surface 110, with multiple first teeth 150 formed on the side facing the first pivot 12. The microwave sensor 40 emits microwaves and receives a microwave sensing signal generated by the reflection of microwaves from an object. The circuit board 50 is electrically connected to the microwave sensor 40 to receive the microwave sensing signal, thereby determining whether an object / person is approaching and transmitting a control signal to an automatic door (not shown) to control its opening and closing. The light source 60 is electrically connected to the circuit board 50 and is controlled to emit a light source of a specific color. In this invention, the microwave sensor 40, the circuit board 50, and the light source 60 are all prior art and not the main creative content of this invention; their detailed structures are not described here. The base 10 also has a latch 16 extending in a direction approximately perpendicular to the base 10, and the latch 16 has a thicker pressing portion 160 at one end away from the base 10.

[0068] The top cover 20 is detachably connected to the base 10. Specifically, the top cover 20 has a pressing hole 21 at the position corresponding to the pressing part 160 of the latch 16. When the top cover 20 and the base 10 are connected, the latch 16 extends into the top cover 20 and the pressing part 160 extends out of the pressing hole 21, thus fixing the top cover 20 and the base 10. Therefore, the top cover 20 will not easily detach from the base 10 if accidentally touched or impacted. When the user needs to remove the top cover 20, they only need to press the pressing part 160 located in the pressing hole 21, and the latch 16 will disengage from the top cover 20. Then, the top cover 20 can be pulled away from the base 10 to separate the top cover 20 from the base 10. The top cover 20 also has a light guide post 22, corresponding to the light source 60 of the base 10. The light guide post 22 is made of transparent light guide material, so that when the light source 60 emits light, the light source can be projected onto the outside of the upper cover 20 through the light guide post 22.

[0069] The movable component 30 is movably disposed in the rotating groove 11 of the base 10 and connected to the microwave sensor 40. Specifically, the movable component 30 has a first rotating seat 31 and a second rotating seat 34. The first rotating seat 31 has a base 310, a first abutment wall 311, a second abutment wall 312, a third abutment wall 313, a first pivot hole 314, a recess 315, and a first engaging member 316. The base 310 is generally semi-circular. The first abutment wall 311, the second abutment wall 312, and the third abutment wall 313 are sidewalls that extend vertically along one side of the base 310 and are interconnected. The first abutment wall 311 and the second abutment wall 312 are respectively connected to the opposite ends of the third abutment wall 313, such that the third abutment wall 313 is located between the first abutment wall 311 and the second abutment wall 312. The first abutment wall 311 and the second abutment wall 312 form a non-zero angle, and the third abutment wall 313 forms a non-zero angle with both the first abutment wall 311 and the second abutment wall 312, causing the first abutment wall 311 and the second abutment wall 312 to extend obliquely away from the third abutment wall 313. The first pivot hole 314 is located in the center of the chassis 310 and is pivotally connected to the first pivot 12 of the base 10, allowing the first rotating seat 31 to rotate around the first pivot 12. The recess 315 is generally arc-shaped, located at the end of the chassis 310 away from the third abutment wall 313, and corresponds to the first engaging portion 15 of the base 10. The first engaging member 316 is a generally curved sheet body located below the recess 315, with both ends connected to the two sides of the recess 315. The first engaging member 316 has a first engaging tooth 317 at the center of the side away from the first pivot 12, which engages with the first teeth 150 of the first engaging part 15.

[0070] The first rotating base 31 also has two side pillars 32 and 33. One end of each side pillar 32 and 33 is connected to the top side of the chassis 310 of the first rotating base 31 and is spaced a predetermined distance apart. The other end extends vertically away from the chassis 310. Each side pillar 32 and 33 has two protruding ribs 320 and 330 arranged side-by-side and extending in opposite directions to strengthen the structural strength of each side pillar 32 and 33. Each side pillar 32 and 33 has a second pivot hole 321 and 331 at the end away from the chassis. The side pillar 32 has a second engaging member 322 at the end away from the chassis 310. The second engaging member 322 is a curved plate approximately 1 / 4 circle in shape, with a second engaging tooth 323 at an approximately 45-degree angle. The side pillar 32 also has a limiting groove 324 communicating with the second pivot hole 321.

[0071] The second rotating seat 34 is rotatably connected to the first rotating seat 31 and can rotate relative to the first rotating seat 31 between a third angle and a fourth angle. Specifically, the second rotating seat 34 has a support frame 340, two second pivots 341, 342, and a second engaging portion 343. The support frame 340 is generally square and is located between the two side posts 32, 33, for mounting the microwave sensor 40 thereon, thereby allowing the microwave sensor 40 to move synchronously with the second rotating seat 34. The two second pivots 341, 342 are respectively connected to opposite sides of the support frame 340 and extend into the two second pivot holes 321, 331 of the two side posts 32, 33, allowing the second rotating seat 34 to rotate around the two second pivots 341, 342. The second engaging portion 343 is an arc-shaped, elongated block located on one side of the support frame 340 adjacent to the second engaging member 322. The second engaging portion 343 has multiple second teeth 344 on the side facing the second engaging member 322, allowing the second engaging teeth 323 of the second engaging member 322 to engage with these second teeth 344. The second rotating seat 34 also has a second limiting block 345 formed on the second pivot 341 adjacent to the limiting groove 324 and extending into the limiting groove 324.

[0072] Based on the above structural configuration, the specific operational applications of the microwave induction device provided by this utility model are as follows:

[0073] When the user installs the microwave sensing device of this utility model in a specific location (usually the wall above an automatic door), the top cover 20 can be removed and the position of the movable part 30 adjusted, thereby adjusting the orientation of the microwave sensor 40. Specifically, the first rotating base 31 can be operated at the first angle (e.g., Figure 4 The position shown) and the second angle (as shown) Figure 5 Rotate between the positions shown. Please refer to... Figure 4 As shown, when the first rotating seat 31 rotates to the first angle, the microwave sensor 40 faces the lower right. At this time, the first abutting wall 311 abuts against the abutting surface 110 of the rotating groove 11, and the first limiting block 13 abuts vertically against the inner wall surface of the third abutting wall 313, thereby limiting the position of the first rotating seat 31 at the first angle. Next, please refer to... Figure 5 As shown, when the first rotating seat 31 rotates to the second angle, the microwave sensor faces the lower left. At this time, the second abutment wall 312 abuts against the abutment surface 110 of the rotating groove 11, and the first limiting block 14 abuts vertically against the inner wall surface of the third abutment wall 313, thereby limiting the position of the first rotating seat 31 at the second angle. Therefore, rotating the first rotating seat 31 can control the microwave sensor 40 to adjust its direction along one of the rotation axes, and the design of the abutment surface 110 and the first limiting blocks 13, 14 can limit the rotation angle of the first rotating seat 31 to between the first angle and the second angle.

[0074] On the other hand, the second rotating seat 34 can be operated at the third angle (e.g. Figure 6 The position shown) and the fourth angle (as shown) Figure 7 Rotate between the positions shown. Please refer to... Figure 6 As shown, when the second rotating seat 34 rotates to the third angle, the microwave sensor 40 forms an angle of approximately 15 degrees with the axis of the first rotating seat 31. At this time, the second limiting block 345 abuts against one side of the limiting groove 324 to limit the position of the second rotating seat 34 at the third angle. Next, please refer to... Figure 7 As shown, when the second rotating seat 34 rotates to the fourth angle, the microwave sensor 40 forms an angle of approximately 65 degrees with the axis of the first rotating seat 31. At this time, the second limiting block 345 abuts against the other side of the limiting groove 324, restricting the position of the second rotating seat 34 at the fourth angle. Therefore, rotating the second rotating seat 34 can control the microwave sensor 40 to adjust its direction along another rotation axis, and the design of the limiting groove 324 and the second limiting block 345 can limit the rotation angle of the second rotating seat 34 to between the third and fourth angles. It is worth noting that this utility model is not limited to the angle range disclosed in the above embodiments and figures. Users can adjust the direction and range of the first, second, third, and fourth angles as needed. Any creation that adjusts the angle to adjust the direction of the microwave sensor does not depart from the protection scope of this utility model.

[0075] In summary, the microwave sensor provided by this utility model, through the adjustable characteristic of the movable part 30, allows for free adjustment of the orientation of the microwave sensor 40. Simultaneously, the limiting means can limit the movable part 30 between the first angle and the second angle, or between the third angle and the fourth angle, thereby preventing excessive deviation in the sensing direction of the microwave sensor 40 due to accidental contact or external impact, which would affect the opening and closing efficiency of the automatic door. Furthermore, the cooperation between the latch 16 and the pressure hole 21 also prevents the upper cover 20 from easily detaching from the base 10 due to accidental contact or external impact.

[0076] The above are preferred embodiments and design drawings of this utility model. The preferred embodiments and design drawings are merely illustrative examples and are not intended to limit the scope of this utility model. Any implementation using equivalent technical means or within the scope of rights covered by the following "Patent Scope" does not depart from the scope of this utility model and falls within the scope of protection of the applicant.
