Description

Technical Field

[0001] This application relates to the technical field of sensor detection, and particularly relates to a performance detection device for automotive intelligent driving sensors. Background Art

[0002] When a vehicle is driving intelligently, it needs to rely on sensors such as radars and cameras to assist in determining the position of the vehicle. Among them, lidar is a relatively important intelligent driving sensor. Due to the usage environment, it is often necessary to perform performance detection on the lidar when it leaves the factory to meet the factory conditions.

[0003] In the prior art, a high and low temperature test chamber is used to simulate and test the environmental temperature of the radar. During use, after the radar is placed in the test chamber, the radar is supported by a tray. When a batch of radars has been detected, in order to reduce the possibility of incorrect detection results caused by excessive temperature difference during the next batch of radar testing, it is necessary to dissipate heat inside the test chamber. When the existing test chamber dissipates heat, it mostly dissipates heat by opening the chamber door. The heat dissipation effect of this method is slow, which prolongs the detection time and reduces the detection efficiency. Therefore, the present invention proposes a performance detection device for automotive intelligent driving sensors to improve this problem. Summary of the Invention

[0004] The purpose of this application is: to solve the problems in the above background art, this application provides a performance detection device for automotive intelligent driving sensors.

[0005] To achieve the above purpose, this application specifically adopts the following technical solutions:

When the sub-plate moves to a position where the length direction of the sub-plate is perpendicular to the length direction of the main plate, the limiting member restricts the relative movement between the main plate and the sub-plate.

[0012] Furthermore, a resistance rod is slidably installed on the limit plate, and the free end of the resistance rod slides through the limit plate and is located in the inner cavity. An extension plate is installed on the resistance rod, and an inclined block is installed on the part of the insertion rod located in the inner cavity. The resistance rod is used to resist the inclined block, and an elastic hook plate is installed on the limit plate. When the elastic hook plate is connected to the extension plate, the sliding of the resistance rod is limited.

[0013] Furthermore, a groove is provided on the box body, a long groove is provided on the inner wall of the groove, a sliding plate slidably connected to the groove is installed on the box door, and a sliding protrusion movably matched with the long groove is installed on the sliding plate.

[0014] Furthermore, an interlayer is provided on the wall thickness of the side wall of the box body, and a heat dissipation port connected to the outside is provided on the side wall of the box body where the interlayer is provided, and an opening on one side of the heat dissipation port passes through the interlayer and is connected to the detection cavity, and a shielding plate for shielding the heat dissipation port is slidably installed in the interlayer, and the free end of the shielding plate passes through the interlayer and is located on the outside, and a waist hole is provided on the free end of the shielding plate, a rotating rod is rotatably installed on the box body, and the free end of the rotating rod is movably connected to the waist hole, a lifting rod for resisting the rotating rod is slidably installed on the box body, and a driving rod is rotatably installed on the box body, one end of the driving rod is movably connected to the box door, and the other end of the driving rod is used to resist the lifting rod.

[0015] Further, an extension rod is installed on the semi-circular arc plate connected to the connecting spring, and a unified plate is installed between multiple extension rods. The extension rod is hinged to the unified plate.

[0016] Further, a limiting buckle is slidably inserted on the inserted rod, and the limiting buckle is used to connect the inserted rods on adjacent limiting plates.

[0017] Further, a plurality of through openings communicating with the interlayer are opened in the detection cavity, and the communication part between the through openings and the heat dissipation openings is blocked or unblocked by a shielding plate.

[0018] The beneficial effects of the present application are as follows:

[0019] 1. When the present application is in use, the radar is placed in the accommodation cavity, and heating simulation is carried out through the electric heating component in the box to detect the radar. After the detection is completed, when the radar is taken out and the box door is opened, the connecting block and the sub-board are rotated so that the sub-board rotates to a position where the length of the sub-board is perpendicular to the length of the main board. Through the cooperation of the limiting member, the movement of the sub-board is restricted. At this time, through the rotation of the rotating board, the sub-board functions as a fan, accelerating the gas flow in the box, thereby facilitating the rapid heat dissipation inside the box and increasing the detection efficiency of the device.

[0020] 2. When the device of the present application detects the radar, the semi-circular arc plate connected to the connecting spring is pulled to slide it in a direction away from the other semi-circular arc plate. The radar is placed between the two semi-circular arc plates, and the pulled semi-circular arc plate is released, so that the two semi-circular arc plates clamp the radar, reducing the movement of the radar in the accommodation cavity, and thus reducing the possibility of damage to the radar due to excessive movement. Moreover, the semi-circular arc plate is arc-shaped, and its contact area with the radar is small. Through the arc-shaped structure, the side wall of the radar can be more exposed, reducing the influence on the detection effect. Through the cooperation between the auxiliary frame and the semi-circular arc plate, the possibility of damage to the radar due to mutual collision or collision with the detection components during detection is greatly reduced, reducing the loss caused to the radar during detection and increasing the practicability of the device.

[0021] 3. When the device is in its normal state in this application, the length direction of the sub-board is in a straight line with the length direction of the main board. At this time, through the cooperation of the limiting member, the movement of the sub-board is restricted. At this time, there are two methods to install the radar. The first method is: release the limiting member and rotate the sub-board so that the accommodating cavity is exposed. This method requires releasing the limiting member and rotating the connecting block and the sub-board, which is rather troublesome. The second method is: directly slide the bracket plate with the sliding block to make it move away from the adjacent bracket plate, expose the accommodating cavity, place the radar, and then slide the bracket plate back to its original position. When the bracket plate slides to the maximum sliding limit, rotate the limiting plate so that the side with the accommodating hole abuts and presses against the protruding block, causing the protruding block to slide into the slide rod channel and make way for the limiting plate through its arc-shaped end until the protruding block aligns with the accommodating hole and is inserted into the accommodating hole. At this time, the rotation of the limiting plate is restricted, and the limiting plate blocks the free end of the slide rod, thereby restricting the sliding of the sliding block. Through this method, only by rotating the limiting plate to block or unblock the slide rod can the bracket plate be limited or the restriction be released, and then the bracket plate can be slid, which is more convenient, can further improve the convenience of placing the radar, and thus increases the detection efficiency of the device.

[0022] 4. When this application is in use, when the sub-board needs to function as a fan, after rotating it with the connecting block, insert the limiting plate into the mounting hole on the main board through the mounting rod. At this time, the body of the limiting plate contacts the side wall of the connecting block, and the other side of the connecting block contacts the main board. At this time, the rotation of the connecting block is restricted. At the same time, press down the insertion rod. When the limiting plate is inserted in place, that is, when the mounting rod is completely inserted into the mounting hole on the main board, the insertion rod aligns with the insertion hole. At this time, release the insertion rod, so that the pushing spring pushes the insertion rod into the insertion hole. The insertion hole is located on one side of the sub-board rotating shaft. At this time, the rotation of the sub-board is restricted by the shielding of the inner wall of the insertion hole by the side wall of the insertion rod, making the sub-board more stable during movement. When the device needs to be detected, connect the limiting plate and the sub-board by inserting the mounting rod into the mounting hole on the sub-board, and then rotate the sub-board and the connecting block to reset. When the sub-board is reset, the limiting plates at the ends of the sub-board contact each other. Since the magnetic poles of the two limiting plates are opposite and attract each other, the rotation of the connecting block is restricted. And because an auxiliary frame is installed in the accommodating cavity, the side wall of the auxiliary frame shields the sub-board, restricting the rotation amplitude of the sub-board so that it will not rotate to a position where the opening of the accommodating cavity is too large, increasing the practicality of the device. By using the same limiting member to restrict the movement of the sub-board in different positions, the practicality of the limiting member is increased. Description of the Drawings

Detailed implementation manners

[0037] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0038] Embodiment 1

[0039] As Figure 1 - Figure 13 shown, a performance detection device for an automotive intelligent driving sensor proposed in Embodiment 1 of the present application includes:

[0040] A box body 1, on which a detection chamber 101 is opened. A box opening 102 is opened on the box body 1 to communicate the detection chamber 101 with the outside. A box door 103 for shielding the box opening 102 is installed on the box body 1. An electric heating component is arranged inside the box body 1 to heat the air inside the box body 1, so that a high-temperature environment can be simulated inside the box body 1, and thus the radar can be tested. During the test, the shielding of the box opening 102 by the box door 103 is removed, so that the radar can be placed into the detection chamber 101. When detecting, the box door 103 is closed to reduce the heat loss in the detection chamber 101. After the detection is completed, the box door 103 is opened to facilitate the cooling of the inside of the box body 1;

[0041] The fixture 2 is installed in the detection chamber 101. The fixture 2 includes a plurality of bracket plates 201. An accommodation chamber 202 for accommodating the radar is formed between the bracket plates 201. The accommodation chamber 202 communicates with the detection chamber 101. The bracket plates 201 are arc-shaped, and the number of the bracket plates 201 is four, so that the cross-section of the accommodation chamber 202 is circular. During use, the movement of the radar in the detection chamber 101 is restricted through the accommodation chamber 202, reducing the possibility of collision damage to the radar caused by excessive movement during detection. The accommodation chamber 202 communicates with the detection chamber 101, enabling the heated air in the detection chamber 101 to smoothly contact the radar for detection;

[0042] The fixture 2 further includes a rotating plate 203 rotatably installed in the detection chamber 101. The rotating plate 203 can be driven by a driving member such as a motor. When detecting the radar, the rotation of the rotating plate 203 drives the rotation of the bracket plates 201. During the process, the radar is driven to rotate by the frictional contact of the inner wall of the bracket plate 201 on the radar. Compared with the existing flat carrier plate, each surface of the radar can contact the hot air more evenly, thereby increasing the detection effect of the device;

[0043] The bracket plate 201 includes a main plate 2011 and a sub-plate 2012. A connecting block 2013 is rotatably installed on the main plate 2011. The connecting block 2013 is rotationally matched with the sub-plate 2012. A limiting member 3 is installed between the main plate 2011 and the sub-plate 2012. When the sub-plate 2012 moves to a position where the length direction of the sub-plate 2012 is perpendicular to the length direction of the main plate 2011, the limiting member 3 restricts the relative movement between the main plate 2011 and the sub-plate 2012. The rotation of the connecting block 2013 causes the main plate 2011 and the sub-plate 2012 to have a tendency to fold along the length direction. The rotation between the sub-plate 2012 and the connecting block 2013 is used to adjust the width direction of the sub-plate 2012. When loading the radar, the sub-plate 2012 can be rotated to expose the accommodation chamber 202, facilitating the placement of the radar into the accommodation chamber 202. After placement, the movement of the sub-plate 2012 is restricted by the limiting member 3, enabling the radar to be relatively stable in the accommodation chamber 202. When heat dissipation is required, the connecting block 2013 and the sub-plate 2012 are rotated so that the wider side of the sub-plate 2012 faces the box opening 102 as Figure 7 shown. At this time, when the door 103 releases the occlusion of the box opening 102, the rotation of the rotating plate 203 drives the movement of a plurality of sub-plates 2012 to form a fan structure, which can accelerate the air flow speed in the box body 1, facilitating the rapid heat dissipation of the interior of the box body 1, enabling the device to quickly detect the next batch of radars, and thus increasing the detection efficiency of the device;

[0044] Compared with the prior art, when in use, the radar is placed into the accommodation cavity 202, and heating simulation is carried out through the electrothermal component in the box body 1 to detect the radar. After the detection is completed, when the radar is taken out and the box door 103 is opened, the connecting block 2013 and the sub-board 2012 are rotated so that the sub-board 2012 rotates to a position where the length of the sub-board 2012 is perpendicular to the length of the main board 2011. Through the cooperation of the limiting member 3, the movement of the sub-board 2012 is restricted. At this time, through the rotation of the rotating plate 203, the sub-board 2012 functions as a fan to accelerate the gas flow in the box body 1, thereby facilitating the rapid heat dissipation inside the box body 1 and increasing the detection efficiency of the device.

[0045] Embodiment 2

[0046] As Figure 6 and Figure 10 shown, Embodiment 2 further discloses the box body 1, the box door 103, the fixture 2 and the limiting member 3 on the basis of Embodiment 1. In Embodiment 2, an auxiliary frame 4 is installed in the accommodation cavity 202, and a through groove is also provided on the auxiliary frame 4 to enable the inside of the auxiliary frame 4 to communicate with the detection cavity 101 through the accommodation cavity 202, reducing the possibility of errors in the detection results caused by the influence of the auxiliary frame 4. A plurality of partition plates 5 are installed in the auxiliary frame 4 to form a plurality of limiting frames 401 in the auxiliary frame 4. Semi-circular plates 402 are installed on both sides of the inner wall of the limiting frame 401. One of the semi-circular plates 402 is fixedly connected to the limiting frame 401, and a connecting spring 403 is installed between the other semi-circular plate 402 and the limiting frame 401. The connecting spring 403 forces the semi-circular plate 402 connected to it to approach the other semi-circular plate 402;

[0047] When the device detects the radar, the semi-circular plate 402 connected to the connecting spring 403 is pulled to slide in a direction away from the other semi-circular plate 402. The radar is placed between the two semi-circular plates 402, and the pulled semi-circular plate 402 is released, so that the two semi-circular plates 402 abut and clamp the radar, reducing the movement of the radar in the accommodation cavity 202, and further reducing the possibility of damage to the radar due to excessive movement. Moreover, the semi-circular plate 402 is arc-shaped, and the contact area between it and the radar housing is small when abutting. Through the arc-shaped structure, more of the side wall of the radar can be exposed, reducing the influence of the semi-circular plate 402 on the detection effect. Through the cooperation between the auxiliary frame 4 and the semi-circular plate 402, the possibility of damage to the radar due to mutual collision during detection or collision between the radar and the detection components is greatly reduced, reducing the loss caused to the radar during detection and increasing the practicality of the device.

[0048] As Figure 2 、 Figure 5 and Figure 9As shown in the figure, in the second embodiment, a mounting plate 6 is installed on the rotating plate 203. A sliding groove 7 is formed in the mounting plate 6. A sliding block 8 that is slidably engaged with the sliding groove 7 is installed on one of the main plates 2011. The sliding direction of the sliding block 8 is such that the bracket plate 201 approaches or moves away from the adjacent bracket plate 201. A sliding rod 9 that slidably penetrates the sliding groove 7 is installed on the sliding block 8. A protruding block 11 is slidably installed on the free end of the sliding rod 9 through a compression spring 10. A limiting slide plate 12 is hinged to the mounting plate 6. A receiving hole 13 for receiving the protruding block 11 is formed in the limiting slide plate 12. When the protruding block 11 is located in the receiving hole 13, the sliding of the sliding block 8 in the sliding groove 7 is restricted. The limiting slide plate 12 is L-shaped. A hole passage is formed in the free end of the sliding rod 9. The compression spring 10 is installed in the hole passage. The protruding block 11 is slidably connected to the hole passage. The top of the protruding block 11 is an arc surface;

[0049] When the device is in its normal state, the length direction of the sub-board 2012 and the length direction of the main board 2011 are on a straight line. At this time, through the cooperation of the limiting member 3, the movement of the sub-board 2012 is restricted. At this time, there are two methods for installing the radar. The first method is: release the limiting member 3 and rotate the sub-board 2012 so that the receiving cavity 202 is exposed. This method requires releasing the limiting member 3 and rotating the connecting block 2013 and the sub-board 2012, which is rather troublesome. The second method is: directly slide the bracket plate 201 on which the sliding block 8 is installed, so that it moves away from the adjacent bracket plate 201, expose the receiving cavity 202, place the radar, and when the placement is completed, slide the bracket plate 201 to reset it. When the bracket plate 201 slides to the maximum sliding limit, rotate the limiting slide plate 12 so that the end with the receiving hole 13 abuts and presses the protruding block 11, causing the protruding block 11 to slide into the hole passage of the sliding rod 9 and make way for the limiting slide plate 12 through its arc-shaped end until the protruding block 11 is aligned with the receiving hole 13 and inserted into the receiving hole 13. At this time, the rotation of the limiting slide plate 12 is restricted, and the limiting slide plate 12 shields the free end of the sliding rod 9, thereby restricting the sliding of the sliding block 8. Through this method, only by rotating the limiting slide plate 12 to shield or release the shielding of the sliding rod 9 can the bracket plate 201 be limited or the limit be released, and then the bracket plate 201 can be slid, which is more convenient and can further improve the convenience of placing the radar, thereby increasing the detection efficiency of the device.

[0050] As Figure 8 、 Figure 12 and Figure 13 As shown in the figure, in the second embodiment, the limiting member 3 includes a limiting plate 301. An inner cavity 302 is formed in the limiting plate 301. An inserting rod 303 is slidably installed in the inner cavity 302 through a pushing spring 3011. The free end of the inserting rod 303 penetrates the inner cavity 302 and is located outside. The pushing spring 3011 forces the inserting rod 303 to move outward;

[0051] The circuit board 2012 is provided with insertion holes 304 for accommodating the insertion rods 303. An installation rod 305 is installed on the limiting plate 301. Installation holes 306 for accommodating the installation rod 305 are provided on both the circuit board 2012 and the main board 2011. The limiting plate 301 is made of a magnetic material, and the magnetic poles of adjacent limiting plates 301 are opposite. The demagnetization temperature of the magnetic material is mostly above 300 degrees Celsius, while the maximum operating temperature range of the lidar does not exceed 100 degrees Celsius. Therefore, the limiting plate 301 will not be demagnetized during detection. The installation rod 305 and the installation hole 306 are in a tightly inserted relationship.

[0052] During use, when the circuit board 2012 needs to function as a fan, after rotating it with the connecting block 2013, insert the limiting plate 301 into the installation hole 306 on the main board 2011 through the installation rod 305. At this time, the body of the limiting plate 301 contacts the side wall of the connecting block 2013, and the other side of the connecting block 2013 contacts the main board 2011. At this time, the rotation of the connecting block 2013 is restricted. At the same time, press down the insertion rod 303. When the limiting plate 301 is inserted in place, that is, when the installation rod 305 is completely inserted into the installation hole 306 on the main board 2011, the insertion rod 303 is aligned with the insertion hole 304. At this time, release the insertion rod 303, so that the pushing spring 3011 pushes the insertion rod 303 into the insertion hole 304. The insertion hole 304 is located on one side of the rotation axis of the circuit board 2012. The rotation of the circuit board 2012 is restricted by the blocking of the inner wall of the insertion hole 304 by the side wall of the insertion rod 303, making the circuit board 2012 more stable during movement. When the device needs to be detected, connect the limiting plate 301 to the circuit board 2012 by inserting the installation rod 305 into the installation hole 306 on the circuit board 2012, and then rotate the circuit board 2012 and the connecting block 2013 to reset. When the circuit board 2012 is reset, the limiting plates 301 at the ends of the circuit board 2012 contact each other. Since the magnetic poles of the two limiting plates 301 are opposite, they attract each other, restricting the rotation of the connecting block 2013. And because the auxiliary frame 4 is installed in the accommodating cavity 202, the side wall of the auxiliary frame 4 blocks the circuit board 2012, restricting the rotation amplitude of the circuit board 2012 so that it will not rotate to a position where the opening of the accommodating cavity 202 is too large, increasing the practicality of the device. The movement of the circuit board 2012 at different positions can be restricted by the same limiting member 3, increasing the practicality of the limiting member 3.

[0053] Such as Figure 13As shown in the figure, in the second embodiment, a contact rod 307 is slidably installed on the limit plate 301. The free end of the contact rod 307 slidably penetrates through the limit plate 301 and is located inside the inner cavity 302. An extension plate 308 is installed on the contact rod 307. A bevel block 3010 is installed on the part of the insertion rod 303 located inside the inner cavity 302. The contact rod 307 is used to contact the bevel block 3010. An elastic hook plate 309 is installed on the limit plate 301. When the elastic hook plate 309 is connected to the extension plate 308, the sliding of the contact rod 307 is restricted. The shape of the elastic hook plate 309 is as Figure 13 shown. Two elastic hook plates 309 are installed on one limit plate 301. There is a space for accommodating the extension plate 308 between the two elastic hook plates 309. The width of this space is greater than or equal to the width of the extension plate 308. The opening of the elastic hook plate 309 facing the extension plate 308 is smaller than the width of the extension plate 308;

[0054] When the insertion rod 303 is inserted into the insertion hole 304, at this time, only by the push of the push spring 3011, the insertion rod 303 is inserted into the insertion hole 304. In order to increase the stability of the insertion rod 303 located in the insertion hole 304, a contact rod 307 is slidably installed on the limit plate 301. After the insertion rod 303 is connected to the insertion hole 304, the contact rod 307 is slid in the direction close to the limit plate 301, so that its end contacts the bevel block 3010. Through the guidance of the inclined surface of the bevel block 3010, the insertion rod 303 is forced to move into the insertion hole 304 and make contact. When the contact rod 307 is pushed to the maximum position, the extension plate 308 contacts the elastic hook plate 309 and forces the elastic hook plate 309 to undergo elastic deformation, resulting in the extension plate 308 entering the space between the elastic hook plates 309. At this time, by restricting the extension plate 308 by the elastic hook plate 309, the sliding of the contact rod 307 is restricted, so that the contact rod 307 can rigidly contact the insertion rod 303, increasing the stability of the insertion rod 303 during use and increasing the practicability of the device;

[0055] When it is necessary to disconnect the connection between the limit plate 301 and the main board 2011, by pulling out the extension plate 308, the contact of the contact rod 307 with the bevel block 3010 is released, and then the insertion rod 303 is slid to disconnect it from the insertion hole 304, which is also relatively convenient.

[0056] As Figure 3 and Figure 4 shown, in the second embodiment, a groove 17 is opened on the box body 1. A long groove 1701 is opened on the inner wall of the groove 17. A sliding plate 1702 slidably connected to the groove 17 is installed on the box door 103. A sliding convex block 1703 movably matched with the long groove 1701 is installed on the sliding plate 1702. The sliding convex block 1703 can rotate and slide in the long groove 1701 to Figure 1Taking the main perspective, the opening direction of the groove 17 faces vertically upward. When it is necessary to remove the shielding of the box door 103 from the box opening 102, first slide the box door 103 upward so that the sliding plate 1702 slides out of the groove 17, and then rotate the box door 103. Through the groove 17 and the sliding plate 1702, multiple corners are formed at the connection opening and closing part between the box door 103 and the box body 1, reducing the possibility of heat leakage through the opening and closing part of the two during the detection of the device and increasing the practicability of the device.

[0057] Embodiment III

[0058] As Figure 1 - Figure 13 shown, Embodiment III further discloses the present application on the basis of Embodiment II. In Embodiment III, a sandwich layer 14 is provided in the wall thickness of the side wall of the box body 1, and a heat dissipation port 15 communicating with the outside is provided on the side wall of the box body 1 where the sandwich layer 14 is provided. One opening on one side of the heat dissipation port 15 penetrates through the sandwich layer 14 and communicates with the detection chamber 101. A shielding plate 16 for shielding the heat dissipation port 15 is slidably installed in the sandwich layer 14. The heat dissipation port 15 has two openings. One opening makes the sandwich layer 14 communicate with the outside, and the other opening makes the sandwich layer 14 communicate with the detection chamber 101. As Figure 11 shown, when detection is required, slide the shielding plate 16 between the two openings of the heat dissipation port 15 to shield the heat dissipation port 15, reducing the possibility of heat loss inside the device;

[0059] The free end of the shielding plate 16 penetrates through the sandwich layer 14 and is located outside. A waist-shaped hole 1601 is provided on the free end of the shielding plate 16. A rotating rod 1602 is rotatably installed on the box body 1. The free end of the rotating rod 1602 is movably connected to the waist-shaped hole 1601. A protrusion is formed on the rotating rod 1602, and the protrusion can rotate and slide in the waist-shaped hole 1601. When the rotating rod 1602 rotates, the inner wall of the waist-shaped hole 1601 is abutted by the protrusion on its free end, thereby pushing the shielding plate 16 upward to release the shielding of the heat dissipation port 15 by the shielding plate 16;

[0060] A lifting rod 1603 for abutting against the rotating rod 1602 is slidably installed on the box body 1. A driving rod 1604 is rotatably installed on the box body 1. One end of the driving rod 1604 is movably connected to the box door 103, and the other end of the driving rod 1604 is used to abut against the lifting rod 1603 to Figure 1 Taking the main perspective, the lifting rod 1603 is slidably installed on the box body 1 in the vertical direction. A groove is provided on the side wall of the box door 103. A block inserted into the groove is installed at the end of the driving rod 1604. The block can rotate and slide in the groove, so that when the box door 103 slides upward, the sliding between the box door 103 and the driving rod 1604 can be used to meet the movement of the box door 103, increasing the feasibility of the device;

[0061] When the device has completed the detection, the box door 103 is opened, and the rotation of the box door 103 drives the driving rod 1604 to rotate, so that the end of the driving rod 1604 that contacts the box door 103 moves downward, and the other end moves upward, thereby resisting the lifting rod 1603, causing the lifting rod 1603 to move upward, and then causing the lifting rod 1603 to push the rotating rod 1602, and the rotating rod 1602 drives the baffle plate 16 to move upward to release the obstruction of the heat dissipation port 15, so that when the box door 103 is opened, the obstruction of the heat dissipation port 15 is also opened, so that when the partition plate 2012 rotates, the air in the detection chamber 101 can be pushed outward from two directions, further increasing the heat dissipation effect of the device and further increasing the detection efficiency of the device.

[0062] In embodiment three, an extension rod 18 is installed on the semi-arc plate 402 connected to the connecting spring 403, and a unified plate 19 is installed between the multiple extension rods 18. The extension rod 18 is hinged to the unified plate 19. When in use, by pulling the unified plate 19, all the semi-arc plates 402 can slide. When placing the radar, there is no need to pull the semi-arc plates 402 one by one, which increases the convenience of the device. The unified plate 19 is hinged to the extension rod 18. When the unified plate 19 is pulled, it can be rotated toward the box mouth 102 to provide a force point for the operator, which is convenient for the operator to apply force. When the pulling is completed, the unified plate 19 falls downward due to the action of gravity, reducing the obstruction of the through groove on the auxiliary frame 4, reducing the impact on radar detection, and increasing the practicality of the device.

[0063] In embodiment three, a limiting buckle 20 is slidably inserted on the insertion rod 303, and the limiting buckle 20 is used to connect the insertion rods 303 on adjacent limit plates 301. One limiting buckle 20 has two channels, which are used to accommodate adjacent insertion rods 303 respectively, and then connect the insertion rods 303 on adjacent limit plates 301. The insertion rod 303 is blocked and restricted by the inner wall of the channel, and the tendency of the limit plates 301 to move away from each other is restricted by hard blocking, which further increases the connection strength between adjacent sub-plates 2012.

[0064] In the third embodiment, a plurality of through openings 21 communicating with the interlayer 14 are formed in the detection cavity 101. The communication portion between the through openings 21 and the heat dissipation opening 15 is blocked or unblocked by a shielding plate 16. The heat dissipation opening 15 is located above the through openings 21. When the shielding plate 16 blocks the heat dissipation opening 15, the cross section of its bottom fills the cross section of the interlayer 14, thereby blocking the communication portion between the through openings 21 and the heat dissipation opening 15, and thus reducing the heat loss of the device during detection. When heat dissipation is required, after the shielding plate 16 releases the blockage of the heat dissipation opening 15, the heat dissipation opening 15, the interlayer 14 and the through openings 21 are communicated. When the sub-board 2012 rotates, more air flow can enter the interlayer 14 and be discharged from the heat dissipation opening 15, increasing the practicability of the device.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application.
