Description

Technical Field

[0001] This utility model relates to the field of inspection robot technology, and in particular to a parking lot inspection robot. Background Technology

[0002] With economic development, artificial intelligence has gradually come into people's view. The construction of smart parks and intelligent communities has brought a series of conveniences to people. Using inspection robots in parking lots can reduce manpower and allow for real-time monitoring of the parking lot's situation.

[0003] A general-purpose inspection robot for parking lots, patent number CN217123156U, has a defect: when the device works outdoors for a long time, a lot of dust will accumulate on the surface of the camera. If it is not cleaned in time, it will affect the camera image and affect its use.

[0004] An existing patent (publication number: CN222134978U) discloses a parking lot inspection robot. This utility model can not only extend and retract by activating a multi-section electric push rod, which can drive a brush plate to reciprocate within a U-shaped frame, but also clean the dust adhering to the camera surface during the reciprocating motion, preventing the problem of unclear images caused by long-term dust accumulation obstructing the camera's view. Furthermore, the dust generated during the cleaning process of the brush plate on the camera can fall into a collection box for collection. The structure is simple and convenient for staff to clean.

[0005] To address the aforementioned issues, existing patents offer solutions. However, these patents only include protective plates and frames on both sides of the robot body, lacking direct protection measures at the front and rear. In complex parking lot environments, vehicles and other objects may collide with the robot from all directions, significantly increasing the risk of damage from front and rear collisions. Furthermore, the protective frames are directly fixed to the protective plates without an effective buffer structure, causing the impact force to be directly transmitted to the robot body during a collision. This makes it difficult to protect internal precision components, easily leading to loosening and damage, and affecting normal operation. Although one side of the protective plate has a raised rubber pad to increase wear resistance and protection, its energy absorption is limited when facing large impacts, failing to effectively reduce damage to the robot body. Moreover, the raised pad is prone to wear after long-term use, reducing its protective performance.

[0006] To address this, a parking lot inspection robot is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a parking lot inspection robot that solves the problem of the aforementioned patents which only have protective plates and frames on both sides of the robot body, lacking direct protection measures at the front and rear. In complex parking lot environments, vehicles and other objects may collide with the robot from all directions, greatly increasing the risk of damage from collisions at the front and rear. Furthermore, the protective frame is directly fixed to the protective plate without an effective buffer structure, causing the impact force to be directly transmitted to the robot body during a collision, making it difficult to protect internal precision components and easily causing components to loosen and be damaged, affecting normal operation. Although there is a rubber pad with a protrusion on one side of the protective plate, which can increase wear resistance and protection, it has limited energy absorption when facing large impact forces and cannot effectively reduce damage to the robot body. Moreover, the protrusion is prone to wear after long-term use, and the protective performance will decrease.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a parking lot inspection robot, including a robot body, a camera is provided on the top of the robot body, a protective mechanism is provided on the outside of the robot body, and a cleaning structure is provided on the right side of the camera;

[0009] The protective mechanism includes a reinforced shell fixedly connected to the outside of the robot body. Telescopic columns are fixedly connected around the outside of the reinforced shell. A buffer spring is sleeved on the outside of the telescopic columns. The inside of the buffer spring is fixedly connected to the outside of the reinforced shell. A protective plate is fixedly connected to the outside of the buffer spring and the telescopic columns. A deformable buffer frame is fixedly connected to the outside of the protective plate.

[0010] Preferably, the cleaning structure includes an outer frame disposed on the right side of the camera, and a servo motor is bolted to the rear side of the top of the outer frame, with the output end of the servo motor passing through the top of the outer frame.

[0016] Preferably, the telescopic column is made of nitrile rubber, which has good elastic deformation properties, and the deformable buffer frame is made of polyurethane elastomer, which has high elasticity, high strength and good tear resistance.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This application enhances the overall structural strength of the robot body by setting up a protective mechanism and reinforcing the shell. When the robot is hit by a collision, the telescopic column contracts under the impact force, and the buffer spring is compressed, converting the kinetic energy generated by the collision into elastic potential energy, which plays a preliminary buffering role. The deformable buffer frame deforms according to the impact force and direction at the moment of collision, further dispersing the impact force and protecting the robot body in all directions. This greatly reduces the risk of damage from collisions at the front and rear, effectively protects the internal precision components, reduces the occurrence of loosening or damage of components due to collisions, and ensures the normal operation of the robot body.

[0019] 2. By setting up a cleaning structure, this application can clean the dust adhering to the surface of its camera lens, so as to avoid long-term dust accumulation that would obstruct the camera lens's view and cause unclear images, ensuring that the robot body can continuously and clearly capture the situation in the parking lot, thereby improving the accuracy and reliability of the inspection work.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A parking lot inspection robot includes a robot body 1, a camera 2 installed on the top of the robot body 1, a protective mechanism 3 installed on the outside of the robot body 1, and a cleaning structure 4 installed on the right side of the camera 2.

[0029] The protective mechanism 3 includes a reinforced shell 31 fixedly connected to the outside of the robot body 1. Telescopic columns 32 are fixedly connected around the outside of the reinforced shell 31. A buffer spring 33 is sleeved on the outside of the telescopic columns 32. The inside of the buffer spring 33 is fixedly connected to the outside of the reinforced shell 31. A protective plate 34 is fixedly connected to the outside of the buffer spring 33 and the telescopic columns 32. A deformable buffer frame 35 is fixedly connected to the outside of the protective plate 34.

[0030] In this embodiment: by setting up the protective mechanism 3 and the cleaning structure 4, when the robot body 1 encounters a collision during its inspection operation in the parking lot, the reinforced shell 31 located on the outside of the robot body 1 enhances the overall structural strength of the robot body 1, enabling it to withstand a certain degree of impact. The telescopic column 32 retracts under the impact force, causing the buffer spring 33 fitted on its outside to be compressed. This process converts the kinetic energy generated by the collision into elastic potential energy, providing initial buffering of the impact force. At the same time, the deformable buffer frame 35 deforms accordingly based on the impact force and direction at the moment of collision, further dispersing the remaining impact force. The protective plate 34, together with the telescopic column 32, the buffer spring 33, and the deformable buffer frame 35, work together to provide all-round protection for the robot body 1. This effectively reduces the risk of damage from collisions at the front and rear, minimizes the possibility of loosening or damage to internal precision components due to collisions, and ensures the continuous normal operation of the robot body 1. Furthermore, the cleaning structure 4 continuously functions during daily inspections, cleaning the dust adhering to the lens surface of the camera 2. As the robot body 1 moves continuously within the parking lot, the camera 2 inevitably accumulates dust. If not cleaned in time, the long-term accumulation of dust will obstruct the lens's view, resulting in unclear images. The cleaning structure 4 prevents this from happening, ensuring that the camera 2 of the robot body 1 can continuously and clearly capture the situation within the parking lot, providing accurate and reliable image information for inspection work, thereby improving the accuracy and reliability of the inspection work.

[0031] Specifically, such as Figure 4 As shown, the cleaning structure 4 includes an outer frame 41 located on the right side of the camera 2. A servo motor 42 is bolted to the rear side of the top of the outer frame 41, and the output end of the servo motor 42 passes through the top of the outer frame 41.

[0032] Specifically, such as Figure 4 As shown, a brush plate 43 is provided on the top right side of the camera 2. The brush plate 43 is located on the top side inside the outer frame 41. The output end of the servo motor 42 is fixedly connected to a lead screw 44. The bottom of the lead screw 44 is threaded to the rear side of the top of the brush plate 43 and passes through it.

[0033] Specifically, such as Figure 4 As shown, a fixing rod 45 is fixedly connected to the front side of the top inside the outer frame 41. The bottom of the fixing rod 45 passes through the top of the brush plate 43. The bottom of the outer frame 41 is connected to a collection frame 46. A collection box 47 is provided inside the collection frame 46. The collection box 47 is located at the bottom of the brush plate 43.

[0034] In this embodiment: By setting the cleaning structure 4, when the robot body 1 performs inspection tasks in the parking lot, the system will monitor the image quality captured by the camera 2 in real time. Once it detects that the image quality has deteriorated due to dust accumulation and the preset cleaning start conditions are met, the robot body 1 will send a cleaning request signal to the remote control terminal based on the preset communication protocol. After receiving the signal and confirming that it is correct, the remote control terminal will immediately send a start command to the robot body 1. At this time, the robot body 1 receives the command and quickly starts the servo motor 42, whose output end drives the lead screw 44 to rotate. Since the lead screw 44 is connected to the rear thread on the top of the brush plate 43, The rotation of the lead screw 44 drives the brush plate 43 to move vertically along the fixed rod 45. The fixed rod 45 acts as a guide to ensure the smooth movement of the brush plate 43. As the brush plate 43 moves, the bristles at its bottom fully contact the lens surface of the camera 2, brushing off the dust adsorbed on the lens. The fallen dust falls directly into the collection frame 46 connected below and is collected in the collection box 47. This process continues, effectively preventing dust from accumulating on the lens for a long time, ensuring that the camera 2 can always clearly capture the situation in the parking lot, providing reliable image data for inspection work, thereby improving the accuracy and reliability of inspection work.

[0035] Specifically, such as Figure 2 As shown, reflective stickers 5 are attached to both sides of the robot body 1, and a light 6 is provided on the right side of the robot body 1.

[0036] Specifically, such as Figure 2 As shown, a solar panel 7 is installed on the left side of the robot body 1, and the solar panel 7 is located on top of the left reflective sticker 5.

[0037] In this embodiment: by setting up reflective sticker 5 and solar panel 7, when the light from vehicles or other objects shines on reflective sticker 5, reflective sticker 5 will reflect the light back, making the robot body 1 more easily visible to people and vehicles in the surrounding environment, significantly improving the visibility of the robot body 1 in the parking lot, reducing the risk of collision, and ensuring the operational safety of the robot body 1. The solar panel 7 is installed on the left side of the robot body 1 and is located on top of reflective sticker 5, so it can receive sufficient sunlight. When there is sunlight during the day, the solar panel 7 converts solar energy into electrical energy and stores it to provide continuous power support for the robot body 1, reducing the robot body 1's dependence on external power sources, extending the robot body 1's battery life, and enabling the robot body 1 to perform inspection work in the parking lot more persistently and stably.

[0038] Specifically, such as Figure 5 As shown, a connecting rod 8 is bolted to the top of the camera 2, and a protective cover 9 is fixedly connected to the top of the connecting rod 8. The protective cover 9 is located on the top of the camera 2.

[0039] Specifically, such as Figure 5 As shown, the telescopic column 32 is made of nitrile rubber, which has good elastic deformation properties, and the deformable buffer frame 35 is made of polyurethane elastomer, which has high elasticity, high strength and good tear resistance.

[0040] In this embodiment: By setting a connecting rod 8 and a protective cover 9, the connecting rod 8 at the top of the camera 2 is connected to the protective cover 9, providing stable support for the protective cover 9, so that the protective cover 9 can be firmly located on top of the camera 2. The protective cover 9 can effectively block objects falling in the parking lot, water droplets, and other foreign objects that may damage the camera 2, preventing them from directly contacting the camera 2, protecting the optical components and electronic components of the camera 2, extending the service life of the camera 2, and ensuring that the camera 2 can always work normally. In addition, the telescopic column 32 is made of nitrile rubber material. The good elastic deformation properties of this material allow the telescopic column 32 in the direction of force to quickly undergo elastic deformation when the robot body 1 is hit, regardless of the direction of the impact. At the same time, the telescopic column 32 in other directions will also undergo elastic deformation. The telescopic column 32 will also deform synchronously. This coordinated deformation design avoids the situation where the other telescopic columns 32 cannot cooperate due to the force on a single telescopic column 32, resulting in poor buffering effect. It can buffer the impact force in an all-round and efficient manner, effectively protecting the robot body 1. In addition, the deformable buffer frame 35 is made of polyurethane elastomer material. With its high elasticity, high strength and good tear resistance, it can not only further disperse the impact force through elastic deformation at the moment of collision, but also withstand a large external force without being easily damaged. The telescopic column 32 and the deformable buffer frame 35 work together to protect the robot body 1 in an all-round way, reduce the damage to the robot body 1 caused by the collision, ensure the safety of the precision components inside the robot body 1, and ensure that the robot body 1 can continue to operate normally.

[0041] Working Principle: During the deployment of the parking lot inspection robot, when the robot is performing inspections within the parking lot, in the event of a collision, the reinforced shell 31 first strengthens the overall structural strength of the robot body 1, giving it a certain impact resistance. The impact force causes the telescopic column 32 to contract, driving the buffer spring 33 to compress, converting the collision kinetic energy into elastic potential energy, thus initially buffering the impact force. Because the telescopic column 32 is made of nitrile rubber, it has excellent elastic deformation performance. Regardless of the direction of the collision, the telescopic column 32 in the direction of force deforms rapidly, while the telescopic columns 32 in other directions also deform synchronously, providing all-round buffering of the impact force. At the same time, the deformable buffer frame 35, with its high elasticity, high strength, and good tear resistance of polyurethane elastomer material, deforms according to the force and direction of the collision, further dispersing the remaining impact force. The protective plate 34 works closely with the telescopic column 32, buffer spring 33, and deformable buffer frame 35 to provide all-round protection for the robot body 1, reducing damage to internal precision components from collisions and ensuring the robot's continuous normal operation. Meanwhile, during the inspection process, the system monitors the image quality captured by the camera 2 in real time. When dust accumulates... When the image quality degrades and the preset cleaning start conditions are met, the robot body 1 sends a cleaning request signal to the remote control terminal according to the preset communication protocol. After confirmation, the remote control terminal issues a start command to the robot body 1. Upon receiving the command, the robot body 1 starts the servo motor 42. The output of the servo motor 42 drives the lead screw 44 to rotate. The lead screw 44 is threadedly connected to the top right side of the brush plate 43, driving the brush plate 43 to move vertically along the fixed rod 45. The fixed rod 45 ensures the smooth movement of the brush plate 43, and the bristles at the bottom of the brush plate 43 make full contact with the lens surface of the camera 2. The dust is brushed off and falls into the collection box 47 of the collection frame 46 below, preventing long-term dust accumulation and ensuring that the camera 2 can always capture clear images, providing reliable image data for inspection work and improving the accuracy and reliability of inspection. In addition, the connecting rod 8 and protective cover 9 on the top of the camera 2 protect the camera 2. The connecting rod 8 firmly supports the protective cover 9, placing it on top of the camera 2. The protective cover 9 effectively blocks objects, water droplets and other foreign objects falling in the parking lot, protecting the optical components and electronic components of the camera 2, extending the service life of the camera 2 and ensuring its normal operation.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
