Technical Field

[0001] The present application relates to the technical field of engineering machinery, and more specifically, to a camera bracket for engineering machinery. Background Art

[0002] Due to the large size of the body, construction machinery often has many blind spots during operation. Therefore, there are many products on the market for intelligent modification of construction machinery, such as body surround view systems, assisted driving systems, intelligent driving systems, and remote driving systems. Basically, the above-mentioned intelligent systems require the installation of cameras on the body of the construction machinery.

[0003] The camera in the prior art is installed on engineering machinery through an ordinary camera bracket. When the machinery is working, the image captured by the camera is prone to produce shaking ghosts. That is, the problem with the prior art is that the image captured by the camera installed on the engineering machinery is not clear.

[0008] To further elaborate, the length of the bracket body is 0.1-100 meters.

[0009] Further elaborating, the first mounting base and the second mounting base are mounted on the engineering machinery equipment by bolts, such as being mounted on a ceiling, a ceiling bracket, or other locations where they can be mounted;

[0010] The first damping vibration absorbing connector and the first mounting base are connected together by eight M6 external hexagonal bolts, and the second composite damping vibration absorbing connector and the second mounting base are connected together by eight M6 external hexagonal bolts;

[0011] The support crossbeam is fastened together with the first damping vibration absorbing connector and the second damping vibration absorbing connector by eight M6 bolts on each side.

[0012] Furthermore, in a preferred embodiment of the present invention, the bracket body includes: a bracket beam; a first telescopic slide rail and a second telescopic slide rail installed on the bracket beam; the outer rails of the first telescopic slide rail and the second telescopic slide rail are installed on the bracket beam by screws; a first bracket arm slidably installed on the inner rails of the first telescopic slide rail and the second telescopic slide rail; a third telescopic slide rail and a fourth telescopic slide rail installed on the bracket beam; and a second bracket arm slidably installed on the third telescopic slide rail and the fourth telescopic slide rail.

[0013] To further explain, two pairs of slide rails are installed on both sides of the bracket beam, the outer rails of the first telescopic slide rail and the second telescopic slide rail are installed on the bracket beam by M4 screws, the outer rails of the third telescopic slide rail and the fourth telescopic slide rail are installed on the bracket beam by M4 screws, the first bracket arm is connected to the inner rails of the first telescopic slide rail and the second telescopic slide rail by M4 screws, and can slide, the second bracket arm is connected to the inner rails of the third telescopic slide rail and the fourth telescopic slide rail by M4 screws.

[0014] Furthermore, in a preferred embodiment of the present invention, the first vibration damping connector and the second vibration damping connector both include: a high-frequency rubber damping structure installed on the support beam; and a low-frequency rubber damping structure embedded in the high-frequency rubber damping structure.

[0015] Furthermore, in a preferred embodiment of the present invention, the low-frequency rubber damping structure is embedded and installed in the high-frequency rubber damping structure in the following manner: the low-frequency rubber damping structure is cylindrical, and the clamping bolt passes through the cylinder of the low-frequency rubber damping structure and is tightened to be tightened in the internal hole of the high-frequency rubber damping structure.

[0016] Furthermore, in a preferred embodiment of the present invention, it also includes: a first slide rail buffer rubber block, the first slide rail buffer rubber block is arranged between the outer rail of the first telescopic slide rail, the second telescopic slide rail and the bracket beam; a second slide rail buffer rubber block; the second slide rail buffer rubber block is arranged between the outer rail of the third telescopic slide rail, the fourth telescopic slide rail and the bracket beam.

[0017] Furthermore, the first damping vibration absorbing connector is inserted into the mounting position of the first mounting base and connected together by eight M6 hexagonal bolts. The first damping vibration absorbing connector is inserted into the mounting position of the end edge of the bracket crossbeam and connected by eight M6 bolts. The first damping vibration absorbing connector includes a high-frequency rubber damping structure, a low-frequency rubber damping structure, and a clamping bolt. Its working method is to insert the low-frequency rubber damping structure into the internal hole of the high-frequency rubber damping structure, and the clamping bolt passes through the cylindrical body of the low-frequency rubber damping structure and is tightened. The low-frequency rubber damping structure can be tightened in the internal hole of the high-frequency rubber damping structure, and at the same time form a composite damping vibration absorption effect. The high-frequency rubber damping structure is kept in a vertical state during installation, which can better absorb the longitudinal wave vibration caused by the vehicle body. The support installation design adopted by the mounting surface of the high-frequency rubber damping structure can eliminate the transverse wave vibration caused by the vehicle body. The low-frequency rubber damping structure and the high-frequency rubber damping structure are combined to have a vibration absorption effect with a wider frequency range.

[0018] The second damping vibration absorbing connector works in the same manner as the first damping vibration absorbing connector. The first damping vibration absorbing connector on one side of the camera bracket and the second damping vibration absorbing connector on the other side can work together to achieve a good vibration absorption effect.

Rubber rail buffers are installed between these rails, two for each rail. The outer rails of the third and fourth telescopic rails are mounted to the support crossbeam using M4 screws. Rubber rail buffers are installed between these rails, two for each rail. These rubber rail buffers installed between the rails and the support crossbeam effectively absorb vibrations transmitted from the vehicle body. After the composite damping and vibration absorbing connectors and composite damping and vibration absorbing connectors absorb vibrations, they provide additional vibration buffering, ensuring clear image quality for the vehicle-mounted camera and minimizing the impact of vibration on camera images.

[0020] Furthermore, in a preferred embodiment of the present invention, it also includes: a first telescopic drive group and a second telescopic drive group installed on the support beam, the first telescopic drive group is used to drive the first support arm to telescope; the second telescopic drive group is used to control the second support arm to telescope.

[0021] The first telescopic drive group and the second telescopic drive group are installed on the support beam through screws, and can drive the first support arm and the second support arm to telescope synchronously.

[0022] Furthermore, it also includes a first camera cover and a second camera cover; the first camera cover and the first bracket arm are fastened together by bolts, and the first camera cover has a mounting hole for the camera, and the camera can be fixed in the camera cover by screws, thereby protecting the camera from sun, rain and collision; the second camera cover and the bracket arm are fastened together by bolts, and the second camera cover has a mounting hole for the camera, and the camera can be fixed in the second camera cover by screws.

[0023] Furthermore, in a preferred embodiment of the present invention, the first telescopic drive group and the second telescopic drive group both include: a screw support and a motor support installed on the support beam; a motor installed on the motor support; a screw slide for connecting the first support arm or the second support arm; a screw bearing installed in the screw support; a screw structure installed in the screw slide and the screw support; a coupling installed on the long axis diameter of the screw structure; and the coupling is connected to the shaft of the motor.

[0024] Among them, the first telescopic drive group and the second telescopic drive group can complete the telescopic function of the camera after control, and the implementation method is as follows: the screw bearing is installed in the screw support, adopting the transition fit method, the screw bearing is installed in the screw support, adopting the transition fit method, the screw nut is embedded and installed on the screw slide, adopting the interference fit installation method, the screw is screwed into the assembled screw slide, and then the two ends of the screw are respectively assembled into the screw support and the screw support, the coupling is installed on the long shaft neck of the screw, the motor is fastened to the motor bracket by screws, and the assembled motor shaft is connected to the coupling. Next, put the entire assembled first telescopic drive group and the first telescopic drive group into the bracket beam, install the screw support and the screw support on the corresponding holes of the bracket beam by screwing, fasten the motor bracket in the bracket beam with screws, adjust the position of the coupling, and then tighten the locking screw on the coupling, fasten the screw slide and the first bracket arm or the second bracket arm together with bolts, so that the motor can rotate, the coupling is transmitted to the screw, the screw drives the screw slide to move, and the screw slide drives the first bracket arm and the second bracket arm to move, thereby realizing the telescopic movement of the camera.

[0025] Furthermore, in a preferred embodiment of the present invention, it further comprises: a boom motion control system for controlling the motion of the bracket boom.

[0026] Furthermore, in a preferred embodiment of the present invention, the boom motion control system includes: a sensor mounting sleeve installed on both sides of the support beam; a support boom position sensor installed on the sensor mounting sleeve; a first position magnetic mark installed on the first support boom and the second support boom, used to mark the innermost position of the first support boom and the second support boom; a second position magnetic mark installed on the first support boom and the second support boom, used to mark the outermost position of the first support boom and the second support boom.

[0027] Among them, taking the first support arm as an example of the operation control process, when the first support arm is in the initial position, the support arm position sensor collects the first support arm position magnetic mark on the first support arm, and the first support arm can be judged by the system to be in the initial position. When the driver triggers the switch of the extension command, the first telescopic drive group starts to work, driving the first support arm to move outward. After reaching the appropriate position, the command is released, and the first support arm stops at the current position. Due to the self-locking principle of the screw transmission, the first support arm can be maintained in the current position and will not move passively. When the first support arm is driven to the outermost maximum position, the magnetic mark of the first support arm position will reach the support arm position sensor. Above the device, the bracket arm position sensor will receive that the first bracket arm has reached the outermost position, and the first telescopic drive group will no longer drive the first bracket arm to extend, but can only drive the first bracket arm to retract; when the first bracket arm is retracted to the initial position, the first position magnetic mark will reach above the bracket arm position sensor, and the bracket arm position sensor will receive that the first bracket arm has reached the innermost position, and the first telescopic drive group will no longer drive the first bracket arm to retract, the first position magnetic mark and the second position magnetic mark respectively mark the innermost position and the outermost position of the first bracket arm that can be moved, and the bracket arm position sensor is used for judgment to prevent damage to the first bracket arm after it moves to the maximum position.

[0028] Furthermore, the electric extension and retraction buttons and the maximum extension and retraction buttons are communicated with the electric telescopic controller. When the electric telescopic controller receives the telescopic command signal, it first judges the position through the signal collected by the sensor. After the position judgment meets the telescopic conditions, the electric telescopic controller will send a transmission signal to the motor driver, and the motor driver drives the motor to work, thereby realizing the synchronous telescopic function of the camera.

[0029] Furthermore, in a preferred embodiment of the present invention, it further includes: a camera telescopic control system communicatively connected to the boom motion control system.

[0030] Furthermore, in the telescopic control of the camera, in this solution, the switch can be long pressed or clicked to adjust the electric telescopic position of the camera bracket; it includes a one-touch adjustment button to achieve one-touch extension to the outermost or retraction to the innermost; a stroke protection setting module can be freely adjusted within the effective stroke, and the system is protected after exceeding the stroke to prevent hardware damage; specifically, when the momentary extension button or the maximum extension button is triggered, the bracket arm position sensors on both sides of the bracket beam respectively detect the extension position of the cameras on both sides. When the maximum extension position is not reached, the telescopic drive system will work to drive the camera to extend. After reaching the maximum extension position, the drive work will be stopped because the sensor detects that it has been extended to the maximum position. When the momentary retraction button or the maximum retraction button is triggered, the bracket arm position sensors on both sides of the bracket beam respectively detect the extension position of the cameras on both sides. When the maximum retraction position is not reached, the telescopic drive system will work to drive the camera to retract. After reaching the maximum retraction position, the drive work will be stopped because the sensor detects that it has been retracted to the maximum position.

At the same time, it also has a good vibration absorption effect on the vibration caused by the vibrating working parts to the camera, thereby overcoming the problem of jitter and ghosting when the camera is mounted on the engineering equipment.

[0072] Among them, taking the first support arm 106 as an example of the operation control process, when the first support arm 106 is in the initial position, the support arm position sensor 702 collects the first position magnetic mark 703 on the first support arm 106, and the first support arm 106 can be judged by the system to be in the initial position. When the driver triggers the switch of the extension command, the first telescopic drive group 9 starts to work, driving the first support arm 106 to move outward. After reaching the appropriate position, the command is released, and the first support arm 106 stops at the current position. Due to the self-locking principle of the screw transmission, the first support arm 106 can remain in the current position and will not move passively. When the first support arm 106 is driven to the outermost maximum position, the magnetic mark of the first support arm 106 position will reach above the support arm position sensor, and the support arm 106 will be in the initial position. The arm position sensor 702 will receive the information that the first support arm 106 has reached the outermost position, and the first telescopic drive group 9 will no longer drive the first support arm 106 to extend, and can only drive the first support arm 106 to retract; when the first support arm 106 is retracted to the initial position, the first position magnetic mark 703 will reach above the support arm position sensor, and the support arm position sensor 702 will receive the information that the first support arm 106 has reached the innermost position, and the first telescopic drive group 9 will no longer drive the first support arm 106 to retract, the first position magnetic mark 703 and the second position magnetic mark 704 respectively mark the innermost position and the outermost position that the first support arm 106 can move, and the support arm position sensor is used for judgment to prevent damage to the first support arm 106 after it moves to the maximum position.

[0073] Specifically, in an embodiment of the present invention, the electric extension and retraction buttons and the maximum extension and retraction buttons are communicated with the electric telescopic controller. When the electric telescopic controller receives the telescopic command signal, it first performs position judgment through the signal collected by the sensor. After the position judgment meets the telescopic conditions, the electric telescopic controller will send a transmission signal to the motor driver, and the motor driver drives the motor to work, thereby realizing the synchronous telescopic function of the camera.

[0074] Specifically, in an embodiment of the present invention, it further includes: a camera telescopic control system communicatively connected to the boom motion control system.

[0075] Furthermore, in the telescopic control of the camera, in this solution, the switch can be long pressed or clicked to adjust the electric telescopic position of the camera bracket; it includes a one-touch adjustment button to achieve one-touch extension to the outermost or retraction to the innermost; a stroke protection setting module can be freely adjusted within the effective stroke, and the system is protected after exceeding the stroke to prevent hardware damage; specifically, when the momentary extension button or the maximum extension button is triggered, the bracket arm position sensors on both sides of the bracket beam 101 respectively detect the extension position of the cameras on both sides, and when the maximum extension position is not reached, the telescopic drive system will work to drive the camera to extend, and when it reaches the maximum extension position, the sensor will stop driving because it detects that it has been extended to the maximum position, and when the momentary retraction button or the maximum retraction button is triggered, the bracket arm position sensors on both sides of the bracket beam 101 respectively detect the extension position of the cameras on both sides, and when the maximum retraction position is not reached, the telescopic drive system will work to drive the camera to retract, and when it reaches the maximum retraction position, the sensor will stop driving because it detects that it has been retracted to the maximum position.
