Description

Technical Field

[0001] This utility model relates to the field of engineering vehicle assisted driving technology, and in particular to a follow-up steering type camera for construction site engineering vehicles. Background Technology

[0002] During the operation of construction vehicles (such as excavators and loaders) on construction sites, drivers often experience increased blind spots due to the vehicle's structure and complex construction environment. This is especially true when reversing, turning, or working in narrow areas, where traditional vehicle-mounted cameras with fixed viewing angles cannot adjust their shooting direction in real time to follow the steering angle of the wheels.

[0003] Although existing cameras support manual or electric rotation, they lack a linkage mechanism with the vehicle's steering system. This can lead to asynchronous rotation, a disconnect between the camera's field of view and the wheel's steering angle, and an inability to automatically align with obstacles behind the trajectory when reversing. Consequently, dynamic blind spots persist on the sides and rear wheel areas of the vehicle, which can easily cause collision accidents.

[0004] Furthermore, in the high-dust environment of construction sites, dust can easily seep into the gaps between the lens and the camera body, causing the mechanism to jam or the image to become blurry.

[0005] To address the above issues, we have launched a follow-up steering camera for construction site vehicles. Utility Model Content

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0031] This utility model discloses a follow-up steering camera for construction site vehicles.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a follow-up steering camera for construction vehicles includes a housing 1, a gear 8 rotatably connected inside the housing 1, a camera module 9 mounted on the top of the gear 8, and the camera end of the camera module 9 extending to the outside of the housing 1.

[0033] An adjusting screw 11 is rotatably connected inside the housing 1. A toothed plate 12 that meshes with the gear 8 is threaded to the outside of the adjusting screw 11. A slide rail 13 is provided between the toothed plate 12 and the inner wall of the housing 1.

[0034] A vertical plate 15 is fixedly connected inside the housing 1. A worm gear 16 is rotatably connected between the vertical plate 15 and the inner wall of the housing 1. A worm wheel 14 that meshes with the worm gear 16 is fixedly connected to the outside of the adjusting screw 11.

[0035] A drive motor 17 is installed on the outside of the upright plate 15, and the output end of the drive motor 17 is connected to the worm gear 16.

[0036] In this embodiment: when the drive motor 17 starts, the output shaft drives the worm 16 to rotate. Through the meshing transmission between the worm wheel 14 and the worm 16, the adjusting screw 11 is driven to rotate. Since the gear plate 12 is threadedly connected to the adjusting screw 11 and is limited by the slide rail 13, the gear plate 12 moves in a straight line, thereby driving the gear 8 meshing with it to rotate. The rotation of the gear 8 directly drives the camera module 9 to deflect around the axis, thereby realizing the adjustment of the camera angle.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the housing 1 is provided with a blocking groove 2, and two blocking plates 3 are slidably connected inside the blocking groove 2, with the camera end of the camera module 9 located between the two blocking plates 3;

[0038] The part of the barrier plate 3 that contacts the camera end of the camera module 9 is made of rubber.

[0039] In this embodiment: when the camera module 9 rotates, the protective cover 10 on the outer side of its camera end continuously slides in contact with the rubber surface of the two side baffles 3; when the camera module 9 deflects, the protective cover 10 pushes the baffles 3 to slide along the baffle groove 2, so that the two baffles 3 are always tightly attached to the surface of the protective cover 10, forming a dynamic sealing barrier to prevent external dust from entering the inside of the housing 1.

[0040] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, push plates 4 are fixedly connected to the blocking plates 3, mounting plates 5 are symmetrically fixedly connected inside the housing 1, sleeves 6 are fixedly connected to the mounting plates 5, springs are provided inside the sleeves 6 and connecting rods 7 are slidably connected, and one end of the connecting rods 7 is fixedly connected to the corresponding mounting plates 5.

[0041] In this embodiment: when the protective cover 10 pushes the blocking plate 3 to move, the push plate 4 fixed to the blocking plate 3 squeezes the connecting rod 7, causing the connecting rod 7 to slide in the sleeve 6 and compress the internal spring; when the camera module 9 returns to its original position, the spring releases its elastic force to push the connecting rod 7 to reset, thereby causing the blocking plate 3 to slide in the opposite direction and maintain the initial contact state with the protective cover 10.

[0042] ReferenceFigure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, a grating touch sensor 19 is fixedly connected to the inner wall of the housing 1, and a grating sensing strip 20 that cooperates with the grating touch sensor 19 is provided on the toothed plate 12.

[0043] In this embodiment: when the toothed plate 12 moves, the grating sensing strip 20 on it and the grating touch sensor 19 fixed on the inner wall of the housing 1 will have relative displacement; the grating touch sensor 19 generates a position signal by detecting the change of the grating stripes, and feeds back the displacement of the toothed plate 12 to the controller 18 in real time, so as to realize the precise closed-loop control of the turning angle of the camera module 9.

[0044] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the camera end of the camera module 9 is connected to a protective cover 10 via a thread;

[0045] In this embodiment, the protective cover 10 is screwed onto the camera end of the camera module 9, which not only protects the lens from scratches but also facilitates disassembly and replacement. Its outer wall and the rubber surface of the baffle plate 3 form a sliding sealing interface, maintaining the dustproof effect during dynamic turning.

[0046] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, the connecting rod 7 elastically abuts against the push plate 4 via a spring inside the sleeve 6;

[0047] In this embodiment, the spring inside the sleeve 6 is always in a pre-compressed state, so that the end of the connecting rod 7 continuously abuts against the push plate 4, providing a constant restoring force to the blocking plate 3, and ensuring that there is no gap between the protective cover 10 and the blocking plate 3.

[0048] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment, a cover plate 21 is connected to the housing 1 by screws;

[0049] In this embodiment, the cover plate 21 is fastened to the housing 1 with screws, forming a sealed maintenance window, which not only protects the internal mechanism from environmental corrosion, but also facilitates the disassembly and maintenance of internal components.

[0050] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 Figure 1 Figure 2 Figure 3 Figure 4As shown, in a preferred embodiment, a wire 22 is installed on the housing 1, and a controller 18 is provided inside the housing 1. The grating touch sensor 19 and the drive motor 17 are both connected to the controller 18.

[0051] In this embodiment: the controller 18 receives the steering wheel angle signal sent by the vehicle computer through the wire 22, and the drive motor 17 drives the gear 8 and the camera module 9 to turn synchronously through the transmission chain of worm 16, worm wheel 14, adjusting screw 11 and gear plate 12, so as to realize the follow-up tracking and shooting with the steering wheels of the engineering vehicle.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
