Description

Technical Field

[0001] This utility model relates to the field of blind spot monitoring technology for engineering machinery, and in particular to a quick-installation blind spot monitoring device for engineering machinery. Background Technology

[0002] During the operation of construction machinery, due to factors such as the large size of the machinery and the complex working environment, there are a large number of blind spots, which can easily lead to safety accidents. At present, in order to solve this problem, the industry usually adopts the method of installing monitoring devices on construction machinery to monitor blind spots. These devices generally include cameras, mounting brackets and display devices. The cameras collect images of blind spots and transmit them to the display devices in the cab to help operators understand the surrounding environment of the machinery in real time.

[0003] However, the installation structure of existing blind spot monitoring devices for construction machinery is often relatively fixed. Most of them are connected to the main body of the construction machinery by welding or multiple bolts. When it is necessary to repair, replace or adjust the installation position of the monitoring device, the disassembly process is cumbersome and requires a lot of time and manpower. Especially in scenarios such as construction sites where the efficiency of operation is required, this inconvenient disassembly and assembly method will seriously affect the progress of the project and make it difficult to meet the actual needs of rapid maintenance and flexible adjustment. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a quick-installation blind spot monitoring device for engineering machinery. The device achieves initial magnetic positioning and auxiliary fastening with the main body of the engineering vehicle through the mounting plate. It uses guide sleeve and mounting plate for limiting and then uses quick-release mechanism to allow the camera to be quickly installed and removed and the angle to be flexibly adjusted, thus solving the problem of cumbersome installation and removal of existing devices that affect efficiency.

[0006] To achieve the above objectives, this utility model proposes a quick-installation blind spot monitoring device for engineering machinery, comprising an engineering vehicle body, a mounting plate, a guide sleeve, an assembly plate, and a quick-release mechanism. The mounting plate includes an assembly back plate, magnetic strips, and fastening bolts. The magnetic strips are located on both sides of the assembly back plate.

One end of the assembly component is installed on the inner top of the rotating housing. The protective housing protects the camera and is installed on the inner bottom of the rotating housing. The top of the protective housing abuts against the other end of the assembly component.

[0007] This utility model discloses a quick-installation blind spot monitoring device for engineering machinery. The mounting plate is fixed to the main body of the engineering vehicle by a magnetic strip for pre-positioning and fastening bolts. After the mounting plate slides along the guide sleeve, it is fixed by the limit bolts. In the quick-release mechanism, the drive device drives the rotating housing and camera to rotate and adjust the angle. The assembly components elastically abut against the protective housing to achieve camera stability and quick release. Through the magnetic attraction, sliding limit and quick-release structure design, it solves the problem of cumbersome disassembly and assembly affecting efficiency of existing devices.

[0023] The embodiments of this utility model are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Rather, the embodiments of this utility model include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0024] The quick-installation blind spot monitoring device for engineering machinery according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0025] like Figures 1-4 As shown, the quick-installation blind spot monitoring device for construction machinery in this embodiment of the present invention may include a construction vehicle body 1, a mounting plate 2, a guide sleeve 3, a mounting plate 4, and a quick-release mechanism 5.

[0026] The mounting plate 2 includes an assembly back plate 21, a magnetic strip 22, and fastening bolts 23. The magnetic strip 22 is located on both sides of the assembly back plate 21, and the fastening bolts 23 are used to fix the mounting plate 2 to the main body 1 of the engineering vehicle.

[0027] Furthermore, there are at least two magnetic strips 22, symmetrically distributed on both sides of the mounting back plate 21, and the magnetic strips 22 magnetically engage with the corresponding mounting surfaces of the engineering vehicle body 1.

[0028] It should be noted that the mounting plate 2 described in this embodiment includes an assembly back plate 21 adapted to the curvature of the mounting surface of the engineering vehicle body 1, magnetic strips 22, and anti-loosening fastening bolts 23. There are two or more magnetic strips 22 symmetrically embedded on the side surface of the assembly back plate 21 facing the engineering vehicle body 1. The outer side of the magnetic strips 22 is covered with a rust-proof and wear-resistant coating and forms a surface contact magnetic attraction with the metal area of ​​the corresponding mounting surface of the engineering vehicle body 1, so as to realize the rapid pre-positioning of the mounting plate 2 and the engineering vehicle body 1. A through hole is opened on the assembly back plate 21, and the anti-loosening fastening bolts 23 pass through the through hole and screw into the pre-set threaded hole of the engineering vehicle body 1, forming a mechanical reinforcement on the basis of magnetic positioning. This ensures the installation stability and avoids the vibration loosening problem that may occur with single magnetic fixation. At the same time, the dual fixing structure of magnetic attraction and bolts takes into account both rapid installation efficiency and long-term reliability.

[0029] The guide sleeve 3 is fixedly connected to one side of the mounting plate 2. The mounting plate 4 is provided with a limit bolt 41, which is used to cooperate with the guide sleeve 3 for limiting.

[0030] It should be understood that the guide sleeve 3 is a hollow structure with a guide groove inside that is compatible with the mounting plate 4. The mounting plate 4 can slide along the guide groove and is locked in position by the limit bolt 41.

[0031] It should be noted that the guide sleeve 3 described in this embodiment is firmly fixed to one side of the mounting plate 2 by welding or high-strength bolts. It is made of high-strength alloy material and has a guide groove that is precisely matched to the size of the mounting plate 4. The inner wall of the groove is coated with a wear-resistant coating. The mounting plate 4 can slide smoothly along the groove. The mounting plate 4 is provided with a limiting bolt 41 corresponding to the groove position of the guide sleeve 3. When the mounting plate 4 slides to the preset installation position, the limiting bolt 41 is tightened so that its end abuts against the limiting hole or limiting protrusion on the side wall of the guide sleeve 3, so as to realize the quick and accurate matching and limiting of the mounting plate 4 and the guide sleeve 3. The limiting bolt 41 is equipped with an anti-loosening washer to ensure the stability of the limiting state, effectively avoid the displacement of the mounting plate 4 caused by the vibration of the construction machinery, and improve the overall structural connection reliability.

[0032] The quick-release mechanism 5 includes a drive unit 51, a drive rod 52, a rotating housing 53, a rotating base 54, an assembly assembly 55, a protective housing 56, and a camera 57.

[0033] The drive device 51 is installed on the top of the mounting plate 4, and its output end is fixedly connected to one end of the drive rod 52. The other end of the drive rod 52 is snapped into the top of the rotating housing 53. The rotating base 54 is rotatably connected to the bottom inner side of the mounting plate 4. The bottom of the rotating housing 53 is fixedly connected to the rotating base 54. One end of the assembly component 55 is installed on the top inner side of the rotating housing 53. The protective housing 56 protects the camera 57. The protective housing 56 is installed on the bottom inner side of the rotating housing 53. The top of the protective housing 56 is in contact with the other end of the assembly component 55.

[0034] It should be understood that the drive device 51 is a motor used to drive the drive rod 52 to rotate, thereby causing the rotating housing 53 to rotate relative to the rotating base 54 and adjusting the angle of the camera 57. The protective housing 56 is a waterproof and dustproof structure. The bottom of the protective housing 56 is an open structure and is threadedly connected to the bottom by a threaded sleeve. The side wall of the protective housing 56 has an opening for placing the camera 57.

[0035] It should be noted that the drive device 51 described in this embodiment uses a servo motor with a self-locking function. It is rigidly connected to the top of the mounting plate 4 via a flange. Its output end is circumferentially fixed to one end of the drive rod 52 via a keyway structure. The other end of the drive rod 52 is machined with an anti-slip toothed chuck, which forms a tight engagement with the toothed groove on the top of the rotating housing 53 to ensure efficient power transmission. The rotating base 54 is rotatably connected to the bearing seat on the bottom inner side of the mounting plate 4 via a deep groove ball bearing. The bearing seat is filled with grease to reduce rotational friction. The bottom of the rotating housing 53 is connected via an annular array The hexagonal socket head cap screws arranged in rows are fixedly connected to the rotating base 54 to form a stable rotating support structure. The top of the assembly component 55 is fixed to the mounting boss on the top inner side of the rotating housing 53 by bolts. The protective housing 56 is made of lightweight alloy material and can be detachably installed in the positioning groove on the bottom inner side of the rotating housing 53 by a snap-fit ​​structure. Its top is connected to the bottom of the assembly component 55 by a buffer pad, which not only provides rigid protection for the camera 57, but also offsets vibration and impact through the elastic force of the assembly component 55, ensuring that the camera 57 always maintains a stable shooting posture during rotation and adjustment.

[0036] Specifically, the mounting plate 21 of the mounting plate 2 is first attached to the mounting surface of the engineering vehicle body 1. The magnetic strips 22 on both sides are used to magnetically attract the metal surface of the engineering vehicle body 1 to achieve quick positioning. Then, the anti-loosening fastening bolt 23 is screwed through the through hole and into the preset threaded hole of the engineering vehicle body 1 to complete the double fixation. Next, the mounting plate 4 is slid along the guide groove of the guide sleeve 3 to the preset position. The limit bolt 41 is turned to make it abut against the limit structure of the guide sleeve 3 to complete the limit fixation. In the quick release mechanism 5, the servo motor of the drive device 51 transmits power through the toothed clasp of the drive rod 52 and the toothed slot of the rotating housing 53, driving the rotating housing 53 and the bottom rotating base 54 to rotate inside the mounting plate 4, realizing the angle adjustment of the camera 57. At the same time, the mounting component 55 forms elastic contact with the protective housing 56 through the support spring 551 and the lower pressure plate 552. With the buckle installation of the protective housing 56, the camera 57 is stably protected and quickly disassembled. The blind spot image collected by the camera 57 can be fed back in real time to assist the operation. The device achieves quick and stable fixing and connection of the mounting plate 2 by combining the magnetic strip 22 with the fastening bolt 23. The guide sleeve 3 cooperates with the mounting plate 4 to achieve quick positioning and limiting. The quick-release mechanism 5 uses the drive rod 52 for transmission, the rotating base 54 for bearing rotation, and the protective shell 56 for snap-on design to achieve quick disassembly and assembly of the camera 57 and flexible angle adjustment. The overall structure solves the problem of cumbersome disassembly and assembly of existing monitoring devices, which affects the efficiency of operation, and meets the needs of quick maintenance and flexible adjustment.

[0037] In one embodiment of this utility model, such as Figures 1-4 As shown, the assembly 55 includes a support spring 551 and a lower pressure plate 552. One end of the support spring 551 is connected to the rotating housing 53, and the other end is connected to the lower pressure plate 552. The bottom of the lower pressure plate 552 abuts against the top of the protective housing 56.

[0038] It should be noted that, in this embodiment, one end of the support spring 551 is welded and fixed to the spring seat on the top inner side of the rotating housing 53, and the other end is threadedly connected to the connecting post on the top of the lower pressure plate 552. The support spring 551 is in a pre-compressed state. The bottom of the lower pressure plate 552 abuts against the matching groove on the top of the protective housing 56 through an arc-shaped contact surface. The edge of the lower pressure plate 552 is provided with a limiting flange, which slides and cooperates with the guide rail on the inner side of the rotating housing 53. This ensures that the elastic force of the support spring 551 acts stably on the protective housing 56, achieving flexible clamping and fixing of the camera 57. At the same time, the sliding guide of the lower pressure plate 552 can prevent the spring from being overloaded. The pre-compressed elastic force is used to offset the vibration and impact during the operation of the engineering machinery, ensuring that the protective housing 56 and the internal camera 57 always maintain a stable posture. When disassembling the protective housing 56, it is only necessary to push the lower pressure plate 552 upward to compress the support spring 551 to release the abutment constraint. Combined with the snap-fit ​​structure of the protective housing 56, quick disassembly and assembly are achieved, taking into account both the reliability of the fixation and the convenience of operation.

[0039] Specifically, one end of the support spring 551 is welded and fixed to the spring seat on the top inner side of the rotating housing 53, and the other end is connected to the top connecting post of the lower pressure plate 552 by a thread. The support spring 551 is in a pre-compressed state. With the help of the pre-compression elastic force, the lower pressure plate 552 is pushed so that its bottom arc-shaped contact surface abuts against the matching groove on the top of the protective housing 56. At the same time, the edge limiting flange of the lower pressure plate 552 slides along the guide rail on the inner side of the rotating housing 53, realizing flexible clamping and fixing of the protective housing 56 and the internal camera 57. This can offset the vibration and impact of operation to maintain stability. When disassembling, pushing the lower pressure plate 552 upward to compress the support spring 551 can release the abutment. With the buckle structure of the protective housing 56, quick disassembly and assembly can be achieved. This structure provides stable clamping force through the pre-compressed spring and is compatible with sliding guide. It not only ensures that the camera 57 is fixed reliably, but also makes the disassembly and assembly of the protective housing 56 and the camera 57 without complicated tools. It solves the problem that the existing monitoring device is cumbersome to disassemble and assemble due to the complex fixing structure, which affects the operation efficiency and meets the needs of rapid maintenance.

[0040] In summary, the quick-installation blind spot monitoring device for engineering machinery of this utility model embodiment has the mounting plate 2 fixed to the main body 1 of the engineering vehicle by the magnetic strip 22 and the fastening bolt 23. The mounting plate 4 slides along the guide sleeve 3 and is fixed by the limiting bolt 41. The driving device 51 in the quick-release mechanism 5 drives the rotating housing 53 and the camera 57 to rotate and adjust the angle. The assembly component 55 elastically abuts against the protective housing 56 to realize the stability and quick release of the camera 57. Through the magnetic attraction, sliding limit and quick release structure design, it solves the problem of the cumbersome disassembly and assembly of the existing device affecting efficiency.
