[0003] The aforementioned technologies and existing technologies mostly use screws for fixing during installation. During installation, the circuit board is mounted on the bottom cover with multiple screws, and then the top cover is mounted on the bottom cover with multiple screws. Thus, when the circuit board needs to be replaced, these screws must be removed before replacement. After the new circuit board is installed, the center screws need to be reinstalled. The entire replacement process requires frequent removal and installation of screws, making it impossible to quickly replace the circuit board. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies where frequent disassembly and installation of screws are required during the replacement process, making it difficult to quickly replace circuit boards. The invention proposes a millimeter-wave radar antenna inner and outer angle compensation circuit board.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a millimeter-wave radar antenna inner and outer angle compensation processing circuit board, comprising a bottom shell, a mounting groove on the top surface of the bottom shell, a circuit board body on the top of the bottom shell, a top cover on the top of the circuit board body, locking blocks on both sides of the mounting groove, locking slots on both sides of the top cover, sliding grooves on the surfaces of the two locking blocks, a fixing plate on the top of the top cover, insertion holes on the surfaces of the top cover and the fixing plate, sleeves at each corner of the top surface of the bottom shell, return springs inside the four sleeves, telescopic rods on the top of the four return springs, a connector at the bottom of the bottom shell, and a protrusion on the top surface of the fixing plate.

[0006] Preferably, the two locking blocks are located at both ends of the bottom shell and are integrally formed with the bottom shell, and the connector is bolted to the bottom shell.

[0007] Preferably, the slots on both sides of the top cover correspond one-to-one with the slots on the top surface of the bottom shell, and the two slots of the bottom shell are engaged in the slots of the top cover.

[0008] Preferably, both of the sliding grooves are located at the top of the block, and the two sliding grooves are mirror images of each other with the top cover as the center.

[0009] Preferably, the four insertion holes on the top surface of the top cover correspond one-to-one with the insertion holes on the top surface of the fixing plate, the protrusion is set on the edge of the top surface of the fixing plate, and the protrusion is integrally formed with the fixing plate, and both ends of the fixing plate are installed in the sliding grooves of the two clips.

[0010] Preferably, all four sleeves are integrally formed with the bottom shell, and the positions of the four sleeves correspond one-to-one with the positions of the insertion holes on the top surface of the top cover.

[0011] Preferably, all four telescopic rods are installed in the sleeve, and the top ends of the telescopic rods all pass through the insertion holes of the top cover and the fixing plate, and the circuit board body is installed in the mounting groove of the bottom shell.

[0012] Beneficial effects

[0013] In this invention, four telescopic rods are pressed down to retract into the insertion holes of the fixing plate. The fixing plate is then pulled out of the sliding groove of the locking block by moving the protruding piece. After the fixing plate is removed, the top cover can be inserted. Once the top cover is removed, the circuit board body in the mounting groove on the top surface of the bottom shell can be disassembled, and a new circuit board body can be installed in the mounting groove. After installation, the sliding grooves on both sides of the top cover are aligned, and then the top cover is pressed down to install it on the bottom shell. The telescopic rod in the sleeve on the top surface of the bottom shell is then inserted into the insertion hole of the top cover. After the top cover is installed, the two telescopic rods on the left end are pressed down first to retract... Retract the plate into the socket of the top cover, align both ends of the fixing plate with the sliding groove of the clip, and push the fixing plate into the sliding groove. After the fixing plate is held in place by the telescopic rod on the right end, press the two telescopic rods on the right end again to retract them into the socket of the top cover, and push the fixing plate again to align the socket of the fixing plate with the socket of the top cover. Then, install all four telescopic rods into the sockets of the top cover and the fixing plate to complete the installation. The whole process only requires pressing the telescopic rods and installing the fixing plate. It does not require frequent disassembly and installation of screws, which solves the problem of the circuit board replacement process requiring frequent disassembly and installation of screws.

[0022] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0023] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0025] Reference Figure 1-5 A millimeter-wave radar antenna inner and outer angle compensation circuit board includes a base shell 1, a mounting groove 13 on the top surface of the base shell 1, a circuit board body 14 on the top of the base shell 1, a top cover 3 on the top of the circuit board body 14, locking blocks 2 on both sides of the mounting groove 13, locking slots 4 on both sides of the top cover 3, sliding grooves 12 on the surface of the two locking blocks 2, a fixing plate 5 on the top of the top cover 3, insertion holes 7 on the surface of the top cover 3 and the fixing plate 5, sleeves 9 at each corner of the top surface of the base shell 1, return springs 11 inside each of the four sleeves 9, telescopic rods 10 on the top of each of the four return springs 11, a connector 8 at the bottom of the base shell 1, a protrusion 6 on the top surface of the fixing plate 5, two locking blocks 2 at both ends of the base shell 1, and the locking blocks 2 are integrally formed with the base shell 1. The connector 8 is bolted to the base shell 1. The slots 4 on both sides of the top cover 3 correspond one-to-one with the slots 2 on the top surface of the bottom shell 1, and the two slots 2 of the bottom shell 1 are engaged in the slots 4 of the top cover 3. The two sliding grooves 12 are both set at the top of the slots 2, and the two sliding grooves 12 are mirror images of the top cover 3. The four insertion holes 7 on the top surface of the top cover 3 correspond one-to-one with the insertion holes 7 on the top surface of the fixing plate 5. The protrusion 6 is set at the edge of the top surface of the fixing plate 5, and the protrusion 6 is integrally formed with the fixing plate 5. Both ends of the fixing plate 5 are installed in the sliding grooves 12 of the two slots 2. The four sleeves 9 are integrally formed with the bottom shell 1, and the positions of the four sleeves 9 correspond one-to-one with the positions of the insertion holes 7 on the top surface of the top cover 3. The four telescopic rods 10 are all installed in the sleeves 9, and the top ends of the telescopic rods 10 all penetrate the insertion holes 7 of the top cover 3 and the fixing plate 5. The circuit board body 14 is installed in the mounting groove 13 of the bottom shell 1.

[0026] The connector 8 is bolted to the base shell 1. The entire millimeter-wave radar is mounted on the vehicle's adapter via the connector 8, and the connector 8 connects to the circuit board body 14 in the mounting groove 13 on the top surface of the base shell 1. Two locking blocks 2 are located at both ends of the base shell 1, and these two locking blocks 2 engage with the locking grooves 4 of the top cover 3, forming a box-like structure with the base shell 1 and the top cover 3. The locking blocks 2 prevent the top cover 3 from moving left or right. The base shell 1 and the top cover 3 protect the circuit board body 14 in the mounting groove 13 on the top surface of the base shell 1. Two sliding... The slots 12 are all located at the top of the locking block 2 for mounting the fixing plate 5. When the two ends of the fixing plate 5 slide into the two slots 12, the top cover 3 is fixed to the bottom shell 1 by the fixing plate 5 to prevent the fixing plate 5 from moving up and down. The protrusion 6 on the left edge of the top cover 3 is used to push the fixing plate 5, making it easier to pull out the fixing plate 5. When the fixing plate 5 is aligned with the top cover 3, the four insertion holes 7 on the top surface of the top cover 3 correspond one-to-one with the insertion holes 7 on the top surface of the fixing plate 5. The positions of the sleeves 9 at each corner of the top surface of the bottom shell 1 correspond to the insertion holes 7 on the top surfaces of the top cover 3 and the fixing plate 5. The positions are one-to-one, with all four telescopic rods 10 installed inside the sleeve 9. Each of the four telescopic rods 10 has a threaded bottom end, and the inner surface of the top of the sleeve 9 also has threads. The threads of the telescopic rods 10 engage with the threads of the sleeve 9, allowing the telescopic rods 10 to be screwed into the sleeve 9. Thus, when the return spring 11 is installed in the sleeve 9, it can also screw the telescopic rods 10 into the sleeve 9. Furthermore, since the telescopic rods 10 only have threads at their bottom ends, and the sleeve 9 only has threads at its top end, when the telescopic rods 10 are screwed into the sleeve 9 and then screwed further down… The thread of the telescopic rod 10 will disengage from the thread of the inner wall of the sleeve 9. After disengagement, the telescopic rod 10 can move up and down in the sleeve 9. When the telescopic rod 10 moves downward, it will squeeze the return spring 11. When the downward force disappears, the telescopic rod 10 will return to its original position by the elastic force of the return spring 11. The top of the telescopic rod 10 passes through the insertion holes 7 of the top cover 3 and the fixing plate 5, so that the fixing plate 5 is fixed in the sliding groove 12 of the two locking blocks 2, preventing the fixing plate 5 from coming out of the sliding groove 12 due to vibration after it is installed in the sliding groove 12.

[0027] When replacing, press down on the four telescopic rods 10, causing them to retract downwards under the downward force. This allows the telescopic rods 10 to retract into the insertion holes 7 of the fixing plate 5. Since the tops of the telescopic rods 10 are all arc-shaped and their curvature matches that of the latch, when the fixing plate 5 is pulled out of the slide groove 12 of the locking block 2 by moving the protrusion 6, the insertion holes 7 of the fixing plate 5 will press against the telescopic rods 10, causing them to retract further downwards until they are finally retracted into the insertion holes 7 of the top cover 3. This allows the fixing plate 5 to be smoothly pulled out of the slide groove 12 of the locking block 2. After the fixing plate 5 is removed, the top cover 3 loses its top fixing component, allowing the fixing plate 5 to move up and down. This allows the top cover 3 to be pulled upwards and removed. After removing cover 3, the circuit board body 14 in the mounting groove 13 on the top surface of the bottom shell 1 can be removed, and the new circuit board body 14 can be installed in the mounting groove 13. During installation, align the positioning hole of the circuit board body 14 with the positioning block on the top surface of the bottom shell 1, and press the circuit board body 14 downward into the mounting groove 13. After the circuit board body 14 is installed, align the sliding grooves 12 on both sides of the top cover 3, and align the locking block 2 with the locking groove 4. Then, the insertion hole 7 of the top cover 3 will align with the sleeve 9. After alignment, press the top cover 3 downward to install the top cover 3 on the bottom shell 1, and insert the sleeve 9 on the top surface of the bottom shell 1 and the telescopic rod 10 in the sleeve 9 into the insertion hole 7 of the top cover 3. After the top cover 3 is installed, first press down the two telescopic rods 10 on the left end to make the left end of the bottom shell 1... The telescopic rod 10 retracts into the insertion hole 7 of the top cover 3. When the telescopic rod 10 is pressed, it is subjected to a downward force and moves downward. After the telescopic rod 10 moves downward, its bottom end will press down on the return spring 11. The return spring 11 is compressed and stores energy. After pressing the left telescopic rod 10, align the two ends of the fixing plate 5 with the slide groove 12 of the locking block 2 and push the fixing plate 5 so that its two ends slide into the slide groove 12. After the fixing plate 5 is pushed into the slide groove 12, release the pressed return spring 11 so that the fixing plate 5 abuts against the return spring 11. When the fixing plate 5 is pushed further, it will abut against the right telescopic rod 10. After abutting, press the two right telescopic rods 10 again to retract the right telescopic rod 10. Insert the telescopic rod 10 into the socket 7 of the top cover 3 and push the fixing plate 5 again, so that the fixing plate 5 presses the telescopic rod 10 on the right end again. When the socket 7 of the fixing plate 5 is aligned with the socket 7 of the top cover 3, the telescopic rod 10 pressed by the fixing plate 5 loses its downward pressing force. When the downward pressing force disappears, because the spiral coil inside the return spring 11 has good elasticity, it will automatically return to its original state, release the stored elastic energy, and push the telescopic rod 10 back to its original position, so that all four telescopic rods 10 are pushed into the socket 7 of the top cover 3 and the fixing plate 5. The fixing plate 5 is fixed by the telescopic rods 10 to complete the replacement of the circuit board. The whole process only requires pressing the telescopic rod 10 and installing the fixing plate 5, without the need for frequent disassembly and installation of screws. Specific Implementation Example 2:

[0029] Reference Figure 1-5 A millimeter-wave radar antenna inner and outer angle compensation processing circuit board is further based on the basic structure in the first specific embodiment. Since all four sleeves 9 are threaded to the bottom shell 1 and the telescopic rod 10 is threaded to the sleeve 9, when the sleeve 9 or the telescopic rod 10 is broken due to external impact, the sleeve 9 or the telescopic rod 10 can be unscrewed and a new sleeve 9 or the telescopic rod 10 can be screwed into the bottom shell 1 or the sleeve 9, so that the fixing parts of the fixing plate 5 are modularized, thereby facilitating subsequent maintenance.

[0030] In summary:

[0031] 1. Press down the four telescopic rods 10 to retract them into the insertion holes 7 of the fixing plate 5. Then, pull the fixing plate 5 out of the sliding groove 12 of the locking block 2 by moving the protrusion 6. After the fixing plate 5 is pulled out, the top cover 3 can be inserted. After the top cover 3 is removed, the circuit board body 14 in the mounting groove 13 on the top surface of the bottom shell 1 can be removed and the new circuit board body 14 can be installed in the mounting groove 13. After installation, align the sliding grooves 12 on both sides of the top cover 3, and then press the top cover 3 down to install it on the bottom shell 1. The telescopic rods 10 in the sleeve 9 on the top surface of the bottom shell 1 should be inserted into the insertion holes 7 of the top cover 3. After the top cover 3 is installed, first press down the two telescopic rods 10 on the left end to retract them. The telescopic rod 10 retracts into the socket 7 of the top cover 3, and the two ends of the fixing plate 5 are aligned with the slide groove 12 of the clip 2. The fixing plate 5 is pushed into the slide groove 12. When the fixing plate 5 is held in place by the telescopic rod 10 on the right end, the two telescopic rods 10 on the right end are pressed again to retract into the socket 7 of the top cover 3. The fixing plate 5 is pushed again to align the socket 7 of the fixing plate 5 with the socket 7 of the top cover 3. All four telescopic rods 10 are installed into the socket 7 of the top cover 3 and the fixing plate 5 to complete the installation. The whole process only requires pressing the telescopic rod 10 and installing the fixing plate 5. It does not require frequent disassembly and installation of screws, which solves the disadvantage of the circuit board that cannot be quickly replaced due to the need for frequent disassembly and installation of screws during the replacement process.
