Description

Technical Field

[0001] This utility model relates to the field of radar technology, and in particular to a radar assembly structure for a cleaning device. Background Technology

[0002] The radar assembly structure of cleaning equipment is a key component that ensures the stable functioning of the radar module during cleaning operations. It is widely compatible with various automated or semi-automated cleaning equipment such as robotic vacuum cleaners, floor scrubbers, and commercial cleaning vehicles. Its design closely matches the complex needs of cleaning scenarios. In actual use, the assembly structure, through preset positioning buckles and buffer pads, can firmly fix the radar module to a suitable position on the top or front of the cleaning equipment. This not only prevents the radar from shifting due to bumps and vibrations when the equipment is moved, but also reduces damage to the internal components of the radar through the buffer design, ensuring the radar detection accuracy and service life.

[0003] Meanwhile, the structure is designed with pre-installed installation interfaces to accommodate different radar models, allowing for the replacement of corresponding radar modules according to the functional requirements of the cleaning equipment without requiring overall equipment modification, thus improving assembly flexibility. Some assembly structures also integrate waterproof and dustproof covers, effectively preventing water stains and dust generated during cleaning from entering the radar's interior, adapting to humid and dusty cleaning environments, and ensuring stable operation of the radar under complex working conditions. Current radar assembly structures for cleaning equipment cannot guarantee the consistency of the laser radar's assembly position and angle, nor can they ensure the electrical distance between the radar and the motherboard. This lack of position and angle consistency can lead to significant differences in the radar detection range and scanning accuracy of cleaning equipment in the same batch. Some equipment may experience detection blind spots due to radar offset. At the same time, the electromagnetic signals generated by the motherboard during operation interfere with the radar's accurate detection, causing the radar to misjudge environmental information. The radar's operating signal also affects the stability of the motherboard circuit, shortening the lifespan of the radar and motherboard, and increasing the frequency and cost of equipment maintenance. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a radar assembly structure for cleaning equipment, aiming to improve the current radar assembly structure of cleaning equipment in the prior art, which cannot guarantee the consistency of the assembly position and angle of the lidar.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see the appendix Figure 1 - Appendix Figure 3An embodiment of this utility model provides a radar assembly structure for a cleaning device, including a housing 1, a main board 9 fixedly connected to the top inner side of the housing 1, a laser radar 10 disposed on the top of the main board 9, radar mounting brackets 8 fixedly connected to the left and right sides of the outer wall of the laser radar 10, a bottom shell 11 disposed on the top left side of the main board 9, a semi-enclosed structure 13 fixedly connected to the bottom of the laser radar 10, a front support structure 17 disposed on the outer wall of the laser radar 10, a back support structure 18 disposed at the bottom of the front support structure 17, and a second radar mounting bracket 14 fixedly connected to the bottom of the back support structure 18.

[0030] Specifically, the lidar 10 is used for detection, capable of emitting laser beams and receiving reflected signals. To ensure the stable installation of the lidar 10, lidar mounting brackets 8 are fixedly connected to both the left and right sides of the outer wall of the lidar 10. These two brackets provide stable support for the lidar 10 from both sides. In addition, a bottom shell 11 is provided on the top left side of the main board 9. At the same time, a semi-enclosed structure 13 is fixedly connected to the bottom of the lidar 10. The semi-enclosed structure 13 may protect the bottom of the lidar 10. A front support structure 17 is also provided on the outer wall of the lidar 10, providing support for the front of the lidar 10. A back support structure 18 is provided at the bottom of the front support structure 17.

[0031] Please see the appendix Figure 4 - Appendix Figure 6 The outer wall of the lidar 10 is provided with a lidar cover 15, the bottom of the lidar cover 15 is provided with a face shell 16, the rear side of the main board 9 is provided with a rear plate 12, the outer wall of the lidar mounting bracket 8 is provided with a screw fixing position 7 near the edge, the top of the lidar cover 15 is fixedly connected with a knob 2, the top front of the top plate 6 is fixedly connected with a long strip 4, the top of the outer shell 1 is fixedly connected with a top plate 6, the top of the top plate 6 is fixedly connected with a protective strip 5 near the edge, and the front of the outer wall of the outer shell 1 is fixedly connected with a warning sign 3.

[0032] Specifically, the mainboard 9 serves as the core control hub of the device, with a rear panel 12 located behind it. The presence of the rear panel 12 further expands the functionality of the mainboard 9. A knob 2 is fixedly connected to the top of the radar cover 15. This knob 2 may have multiple functions, such as adjusting the opening and closing angle of the radar cover 15. The outer shell 1 serves as the external protective housing of the device, with a top plate 6 fixedly connected to its top. The top plate 6 is tightly connected to the outer shell 1, together forming a closed or semi-closed space, providing reliable protection for the internal mainboard 9 and lidar 10, preventing them from being damaged by external collisions and pressure.

[0033] Working principle: The lidar 10 is fixed to the base shell 11 via the lidar mounting bracket 8. It is then secured to the lidar mounting bracket 8 with external screws, and finally, the locking screws on the lidar mounting bracket 8 are used to secure it to the base shell 11. The lidar is then positioned horizontally by the front support structure 17 and the rear support structure 18 of the lidar mounting bracket 8. The deformation of the material itself and the assembly process create protrusions or depressions, resulting in different angles of the emitted laser beam. This prevents calibration errors and ensures consistent ranging. Therefore, the lidar is fixed to the base shell 11 via the lidar mounting bracket 8. Both ends of the motor have output shafts, and the front and rear support structures 17 and 18 of the mounting bracket ensure the consistency of the lidar 10's assembly position and angle. The semi-enclosed structure 13 at the bottom of the lidar mounting bracket 8 maintains the electrical distance between the lidar 10 and the main board 9, providing a certain degree of protection.
