Description

Technical Field

[0001] The utility model relates to a patrol car, in particular to a multi-road condition unmanned patrol car, belonging to the technical field of unmanned patrol cars. Background Art

[0002] A patrol car is a vehicle specially designed and developed for public security and peacekeeping personnel. The most commonly used patrol cars in the market are four-wheel steering electric patrol cars, which can accommodate 2-8 people and are equipped with warning lights, horns and shouting devices. This type of car can be roughly divided into open-door patrol cars, patrol cars, and patrol vans. Patrol cars can be divided into electric and fuel types according to the power source, including semi-enclosed and fully enclosed types. Before using an electric patrol car, you should pay attention to check whether the vehicle is in good condition, such as whether the tire pressure is sufficient, whether the front and rear brakes are sensitive, whether there are any abnormalities in the vehicle, whether the screws are loose, and whether the battery is fully charged. When the electric patrol car is just started, it should be accelerated slowly to avoid instantaneous rapid acceleration to damage components. In order to extend the life of the battery and motor, the foot pedal should be used when the electric patrol car is started and climbing. Under the premise of ensuring safety, frequent braking and starting should be reduced as much as possible during driving to save electricity;

DETAILED DESCRIPTION

[0033] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0034] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0035] like Figure 1-6 As shown, an embodiment of the utility model provides a multi-road condition unmanned patrol vehicle, which is composed of a main body mechanism 10 and a protection mechanism 20.

[0036] The main body 10 includes a patrol car body 11, a chassis 19 and a wheel 13. An image collector 12 is installed on the top of the patrol car body 11. The image collector 12 can be adjusted in multiple directions to collect information and transmit the information to the control center through the transmission equipment of the patrol car body 11. The chassis 19 is installed at the bottom of the patrol car body 11. The wheel 13 is installed at one end of the drive shaft of the patrol car body 11. A mounting groove 34 is integrally formed on one side of the chassis 19. A fender 15 is provided on one side of the wheel 13. It is fixedly connected to the patrol car body 11, and mud protection is provided by a mud guard 15 to reduce mud splashing. Display screens 14 are installed on both sides of the patrol car body 11, and information is conveniently displayed through the display screens 14. A storage space is provided on one side of the patrol car body 11 for temporarily storing tools or spare parts. A cover plate 17 is hinged on one side of the patrol car body 11, and a handle 18 is fixedly connected to one side of the cover plate 17. The cover plate 17 can be opened to maintain the internal equipment of the patrol car body 11 or use the tools stored in the storage space.

[0037] In one embodiment, in order to facilitate the removal of mud and debris adhered to the wheel 13 when necessary, a slot 35 is opened on one side of the mudguard 15, and a scraper 16 is clamped inside the slot 35. By connecting the scraper 16 to the mudguard 15, when the wheel 13 rotates, the scraper 16 scrapes off the mud and debris on the surface of the wheel 13.

[0038] In one embodiment, in order to perform an escape operation when the patrol car body 11 cannot move, a hydraulic cylinder 31 is symmetrically installed on one side of the chassis 19, and the piston rod of the hydraulic cylinder 31 is fixedly connected to a support frame 32, and one side of the support frame 32 is symmetrically rotatably connected to an auxiliary wheel 33. The auxiliary wheel 33 can assist in the movement and support of the patrol car body 11 when needed.

[0039] The protective mechanism 20 includes a protective plate 26, a mounting seat 27 and a shock absorber 28. The mounting seat 27 is arranged inside the mounting groove 34. Second bolts 29 are symmetrically threadedly connected on both sides of the mounting seat 27. One end of the second bolt 29 is threadedly connected to the chassis 19. The mounting seat 27 and components such as the protective plate 26 are installed and fixed by the second bolts 29, so that the protective plate 26 can be removed and replaced when the protective plate 26 is damaged. The shock absorber 28 is symmetrically installed inside the mounting seat 27. One end of the shock absorber 28 is fixedly connected to the protective plate 26. A rubber pad 25 is symmetrically fixedly connected to one side of the protective plate 26. One side of the rubber pad 25 is fixedly connected to the chassis 19. The rubber pad 25 enhances the stability of the protective plate 26 while protecting the contact surface between the protective plate 26 and the chassis 19 to prevent wear of the contact surface.

[0040] In one embodiment, in order to enhance the protection effect of the chassis 19, a front guard plate 21 and a rear guard plate 22 are respectively provided on one side of the chassis 19, and both sides of the front guard plate 21 and the rear guard plate 22 are fixedly connected with a fixing plate 23, and the interior of the fixing plate 23 is symmetrically threaded with a first bolt 24, and one end of the first bolt 24 is threadedly connected to the chassis 19.

[0041] When the utility model is working: the patrol car body 11 cooperates with the wheels 13 to patrol in the designated area. During the patrol, the image collector 12 collects information and transmits it to the dispatch center. When the patrol car body 11 cannot move due to road conditions, the hydraulic cylinder 31 is started to push the support frame 32 to contact the ground, and the patrol car body 11 is lifted up in cooperation with the auxiliary wheels 33, so that the staff can easily get the patrol car body 11 out of trouble. The auxiliary wheels 33 can assist in the movement and support of the patrol car body 11 when necessary. When the road surface is uneven, the raised part of the road surface contacts the protective plate 26, and the protective plate 26 cooperates with the front guard plate 21 and the rear guard plate 22 to protect the chassis 19 to prevent the wear of the chassis 19 from affecting the normal use of the patrol car body 11. When the protective plate 26 contacts the road surface or other objects, it squeezes the shock absorber 28 and the rubber pad 25 to reduce the collision. The impact of the vibration on the patrol car body 11, the rubber pad 25 enhances the stability of the protective plate 26, and protects the contact surface between the protective plate 26 and the chassis 19 to prevent the protective plate 26 from wearing the chassis 19 when vibrating. When the road is muddy, if the wheel 13 adheres to too much mud, the patrol car body 11 will clean the wheel 13 when it returns, and the scraper 16 will be stuck in the card slot 35. When the wheel 13 adheres to mud again, the scraper 16 will scrape off the attachments on the surface of the wheel 13 to prevent the attachments from affecting the normal use of the wheel 13. When the road surface is icy, it is necessary to open the cover 17 to install anti-skid chains for the wheel 13, and reduce the driving speed of the patrol car body 11. When necessary, the patrol car body 11 is manually recovered. The display screens 14 on both sides of the patrol car body 11 display information and put advertisements, and can warn pedestrians when used at night.

[0042] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
