Description

Technical Field

[0001] This invention relates to the field of video surveillance technology, specifically a multifunctional mobile base station 4K video surveillance device. Background Technology

[0002] Camera surveillance uses fiber optics, coaxial cables, or microwaves to transmit video signals within a closed loop. It forms an independent and complete system from camera to image display and recording, and can reflect the monitored object in real time, vividly and realistically. It is one of the most commonly used surveillance and protection devices.

[0003] Patent CN101890975B discloses a hand-push mobile camera vehicle, including a cargo platform and wheels. Its feature is that it also includes a chassis arranged in parallel below the cargo platform; the wheels include two sets of front wheels and two sets of rear wheels, each connected to the chassis via an extension arm; each set of wheels has a wheel connecting shaft vertically arranged on its axle, and the wheel connecting shaft is rotatably connected to the end of the corresponding extension arm, and the other end of each extension arm is pivotally connected to the chassis via a vertically arranged pivot. When in use, this hand-push mobile camera cart is not limited by guide rails, allowing for a wider shooting range. When the shooting location is relatively spacious, the four extension arms can be extended to mount a small jib arm, making the wheels provide more stable support for the cart and increasing the shooting range. When shooting in narrow spaces such as alleyways, the four extension arms can be retracted to the center, making it adaptable to various shooting locations and possessing a wide range of applications. Although this invention solves the aforementioned problems, it still has limitations in shooting height and range. Therefore, a multi-functional mobile base station 4K video monitoring device is proposed to address these issues. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a multifunctional mobile base station 4K video monitoring device to address the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a multifunctional mobile base station 4K video monitoring device, including a housing, a push handle provided on the left side of the housing, a support mechanism provided on the outer wall of the housing, a lifting mechanism provided inside the housing, a moving mechanism provided on the right side of the housing, and a camera provided on the top of the lifting mechanism. The lifting mechanism includes a drive shaft, a drive gear, a large gear, a coarse gear, a power transmission shaft, a lifting column, and meshing teeth. The drive shaft is rotatably connected to the inner wall of the housing, the drive gear is fixedly connected to the outer circumferential surface of the drive shaft, the power transmission shaft is rotatably connected to the inner wall of the housing, the large gear is fixedly connected to the outer circumferential surface of the power transmission shaft, the coarse gear is fixedly connected to the outer circumferential surface of the power transmission shaft, the lifting column is slidably connected to the inner wall of the housing, and the meshing teeth are formed on the outer circumferential surface of the lifting column. The lifting mechanism also includes a fixing pin and bent teeth, and the fixing pin is supported by a torsion spring. The device is connected to the top of the housing. The curved gear is fixedly connected to the outer circumference of the drive shaft. The fixing pin contacts the curved gear. The drive gear meshes with the large gear, and the coarse gear meshes with the meshing teeth. A motor is installed at one end of the drive shaft. When the device needs to operate, the motor is started to drive the drive shaft to rotate. The rotation of the drive shaft drives the drive gear to rotate, which in turn drives the large gear at the bottom to rotate. The rotation of the large gear drives the power transmission shaft to rotate, which in turn drives the coarse gear to rotate. When the coarse gear rotates, the meshing teeth drive the lifting column to rise. The rise of the lifting column drives the camera to rise, increasing the camera's height and thus increasing the device's imaging area. At the same time, when the lifting column rises, the drive shaft rotates clockwise, driving the curved gear to rotate. The arc surface of the curved gear causes the fixing pin to bounce up and down. When the curved gear stops rotating, the fixing pin will be locked between the grooves of the curved gear, providing support and fixation for the lifting column. This prevents unnecessary wear and tear on the motor and internal gears caused by supporting the lifting column when the device is stationary.

[0006] Preferably, the support mechanism includes a limiting plate, a telescopic rod, an inner rod, a support leg, a transmission arc, a pinion, a gear, a chamfer, a sloping surface, a groove, and a vertical groove. The limiting plate is fixedly connected to the bottom of the lifting column, the telescopic rod is fixedly connected to the outer wall of the limiting plate, the inner rod is rotatably connected to the outer wall of the housing, the sloping groove is formed on the outer wall of the inner rod, the support leg is slidably connected to the inner wall of the sloping groove, the transmission arc is fixedly connected to the outer surface of the telescopic rod, the pinion is rotatably connected to the outer wall of the transmission arc, the gear is fixedly connected to the outer wall of the support leg, the vertical groove is formed on the outer wall of the support leg, and the chamfer is provided on the outer surface of the inner rod. The support mechanism also includes a positioning block, a long sloping rod, a short sloping rod, a support block, a return spring, and a sliding column. The positioning block is fixedly connected to the outer surface of the support leg, the long sloping rod is rotatably connected to the outer wall of the positioning block, the short sloping rod is rotatably connected to the bottom of the long sloping rod, the sliding column is slidably connected to the inner wall of the positioning block, the support block is fixedly connected to the bottom of the sliding column, and one end of the return spring is fixedly connected to... At the bottom of the positioning block, the other end of the reset spring is fixedly connected to the top of the support block. The short and long inclined rods are rotatably connected by a torsion spring. The pinion meshes with the gear column, and the transmission arc contacts the inclined surface. A spring is installed inside the telescopic rod. When the device is started, the lifting column drives the limiting plate to rise. As the limiting plate rises, the telescopic rod rises, which in turn drives the pinion to move upward and meshes with the transmission gear column, driving the support leg to move downward. When the telescopic rod rises, it also drives the transmission arc to move upward. During the movement, the transmission arc is guided by the inclined surface, which drives the inner rod to unfold outward. As the inner rod unfolds outward, the support leg also unfolds downward, providing support and fixation for the device and preventing it from tipping over due to an excessively high center of gravity. At the same time, when the support leg moves downward, it drives the support block to move downward. After the support block contacts the ground, the pressure of the ground drives the sliding column to move upward, which in turn squeezes the reset spring and drives the long inclined rod to move downward. The downward movement of the long inclined rod drives the movement until its horizontal surface is in complete contact with the ground, achieving better support for the device.

[0007] Preferably, the moving mechanism includes a crash barrier, a stress-relieving column, a stress-relieving spring, a brake column, a brake plate, and a fixing block. The fixing block is fixedly connected to the outer wall of the machine body housing. The stress-relieving column is fixedly connected to the bottom of the fixing block. The crash barrier is slidably connected to the outer wall of the stress-relieving column. One end of the stress-relieving spring is fixedly connected to the bottom of the fixing block, and the other end of the stress-relieving spring is fixedly connected to the top of the crash barrier. The brake column is fixedly connected to the bottom of the fixing block, and the brake plate is fixedly connected to the bottom of the brake plate. The moving mechanism also includes casters, cylinders, and other components. The system comprises a crossbar, a top frame, a positioning post, a bottom frame, a bottom beam, a first diagonal brace, and a second diagonal brace. The casters are fixedly connected to the bottom of the housing. The top frame is fixedly connected to the bottom of the housing. The bottom frame is located at the bottom of the top frame. A sliding groove is formed on the inner wall of the bottom frame. One end of the second diagonal brace is rotatably connected to the inner wall of the top frame, and the other end is slidably connected to the inner wall of the sliding groove. One end of the first diagonal brace is rotatably connected to the inner wall of the top frame, and the other end is rotatably connected to the inner wall of the bottom frame. The positioning post is rotatably connected between the second diagonal brace and the first diagonal brace. The bottom beam is fixedly connected to the inner wall of the bottom frame, the crossbar is fixedly connected to the inner wall of the first diagonal bar, one end of the cylinder is rotatably connected to the outer wall of the bottom beam, and the other end of the cylinder is rotatably connected to the outer wall of the crossbar. The brake column is slidably connected to the inner wall of the housing. The anti-collision plate is made of elastic material. When the device is pushed to move, the height of the device may obstruct the operator's partial view and may cause it to collide with some obstacles. At this time, the impact force drives the anti-collision plate to retract inward and squeeze the relief spring along the limit of the relief column to relieve the impact force. When the anti-collision plate retracts inward, it drives the brake column to move downward. The brake column drives the brake plate to move downward, so that the brake plate contacts the ground and generates friction to stop the device from moving and avoid greater damage. When the device is moved to the designated position, the cylinder is activated to drive the crossbar to move upward. The upward movement of the crossbar drives the second diagonal bar to move towards the middle along the fixed block. At the same time, the second diagonal bar moves towards the middle and, under the limit of the top housing, drives the bottom frame to move downward and contact the ground, thereby lifting the device and stopping its movement to prevent displacement of the device during operation.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This multi-functional mobile base station 4K video monitoring device, with the cooperation of the lifting column, camera, bevel gear, and fixing pin, the lifting column rises and drives the camera to rise, increasing the camera's height and thus increasing the device's imaging area. At the same time, the arc surface of the bevel gear causes the fixing pin to bounce up and down. When the bevel gear stops rotating, the fixing pin will be locked between the teeth of the bevel gear, providing support and fixation for the lifting column and preventing unnecessary wear and tear on the motor and internal gears caused by supporting the lifting column when the device is stationary.

[0009] 2. In this multi-functional mobile base station 4K video monitoring device, with the cooperation of the support block, long diagonal rod, sliding column, and return spring, after the support block contacts the ground, the pressure of the ground drives the sliding column to move upward, thereby squeezing the return spring and driving the long diagonal rod to move downward. The downward movement of the long diagonal rod drives the device to finally make its horizontal surface fully contact the ground, thus achieving a better support effect for the device.

[0010] 3. In this multi-functional mobile base station 4K video monitoring device, with the cooperation of the second diagonal rod, the housing, and the bottom frame, the second diagonal rod moves towards the middle and, under the limit of the top housing, drives the bottom frame to move down and contact the ground, thereby lifting the device and stopping its movement, preventing displacement of the device during operation.

Detailed Implementation

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The curved tooth 309 is fixedly connected to the outer circumferential surface of the transmission shaft 301. The fixing pin 308 contacts the curved tooth 309. The transmission gear 302 meshes with the large gear 303, the coarse gear 304 meshes with the meshing tooth 307, and a motor is provided at one end of the transmission shaft 301. The support mechanism 5 includes a limiting plate 501, a telescopic rod 502, an inner rod 503, a support leg 504, a transmission arc 505, a pinion 506, a gear 507, a chamfered surface 508, a sloping groove 509, and a vertical groove 510. The limiting plate 501 is fixedly connected to the bottom of the lifting column 306. The telescopic rod 502 is fixedly connected to the outer wall of the limiting plate 501. The inner rod 503 is rotatably connected to the outer wall of the housing 1. The sloping groove 509 is formed on the outer wall of the inner rod 503. The support leg 504 is slidably connected to the inner wall of the sloping groove 509. The transmission arc 505 is fixedly connected to the outer surface of the telescopic rod 502. The pinion 506 is rotatably connected to the outer wall of the transmission arc 505. The gear 507 is fixedly connected to the outer wall of the support leg 504. The vertical groove 510 is formed on the outer wall of the support leg 504. The chamfered surface 508 is provided on the outer surface of the inner rod 503. The support mechanism 5 also includes a positioning block 511, a long inclined rod 512, a short inclined rod 513, a support block 514, a return spring 515, and a sliding column 516. The positioning block 511 is fixedly connected to the outer surface of the support leg 504. The long inclined rod 512 is rotatably connected to the outer wall of the positioning block 511. The short inclined rod 513 is rotatably connected to the bottom of the long inclined rod 512. The sliding column 516 is slidably connected to the inner wall of the positioning block 511. The support block 514 is fixedly connected to the bottom of the sliding column 516. One end of the return spring 515 is fixedly connected to the bottom of the positioning block 511, and the other end of the return spring 515 is fixedly connected to the top of the support block 514.

The transmission arc 505 contacts the inclined surface 508. A spring is provided inside the telescopic rod 502.

[0015] Working principle: When the device needs to operate, the motor starts and drives the transmission shaft 301 to rotate. The rotation of the transmission shaft 301 drives the transmission gear 302 to rotate, which in turn drives the bottom large gear 303 to rotate. The rotation of the large gear 303 drives the power transmission shaft 305 to rotate, which in turn drives the coarse gear 304 to rotate. When the coarse gear 304 rotates, the meshing teeth 307 drive the lifting column 306 to rise. The rise of the lifting column 306 drives the camera 6 to rise, increasing the height of the camera 6 and increasing the imaging area of ​​the device. At the same time, when the lifting column 306 rises, the transmission shaft 301 rotates forward and drives the curved tooth 309 to rotate. The arc surface of the curved tooth 309 will drive the fixing pin 308 to bounce up and down. When the curved tooth 309 stops rotating, the fixing pin 308 will be locked between the teeth of the curved tooth 309 to support and fix the lifting column 306, avoiding unnecessary wear and tear on the motor and internal gears due to supporting the lifting column 306 when the device is stationary. When the device is started, the lifting column 306 drives the limiting plate 501 to rise. As the limiting plate 501 rises, the telescopic rod 502 rises, which in turn drives the pinion 506 to move upward. At the same time, the pinion 506 engages with the transmission gear 507, which drives the support leg 504 to move downward. When the telescopic rod 502 rises, it also drives the transmission arc 505 to move upward. During the movement of the transmission arc 505, it is guided by the inclined plane 508, which drives the inner rod 503 to unfold outward. As the inner rod 503 unfolds outward, the support leg 504 also unfolds downward, which provides support and fixation for the device and prevents the device from tipping over due to excessive center of gravity. At the same time, when the support leg 504 moves downward, it drives the support block 514 to move downward. After the support block 514 contacts the ground, the pressure of the ground drives the sliding column 516 to move upward, which in turn squeezes the return spring 515 and drives the long inclined rod 512 to move downward. The long inclined rod 512 moves downward, driving the movement until its horizontal surface is in complete contact with the ground, thus achieving a better support effect for the device.

[0016] Please see Figures 1-8Based on the above embodiments, in another embodiment of the present invention, the moving mechanism 4 includes a crash plate 401, a stress-relieving column 402, a stress-relieving spring 403, a brake column 404, a brake plate 405, and a fixing block 406. The fixing block 406 is fixedly connected to the outer wall of the machine body housing 1. The stress-relieving column 402 is fixedly connected to the bottom of the fixing block 406. The crash plate 401 is slidably connected to the outer wall of the stress-relieving column 402. One end of the stress-relieving spring 403 is fixedly connected to the bottom of the fixing block 406, and the other end of the stress-relieving spring 403 is fixedly connected to the top of the crash plate 401. The brake column 404 is fixedly connected to the bottom of the fixing block 406, and the brake plate 405 is fixedly connected to the bottom of the brake plate 405. The moving mechanism 4 also includes a caster wheel 407, a cylinder 408, a crossbar 409, a top frame 410, a positioning column 411, a bottom frame 412, a bottom beam 413, a first diagonal bar 414, a second diagonal bar 415, and a caster wheel 407. A top frame 410 is fixedly connected to the bottom of the housing 1. A bottom frame 412 is located at the bottom of the top frame 410. A slide groove 416 is formed on the inner wall of the bottom frame 412. One end of a second diagonal rod 415 is rotatably connected to the inner wall of the top frame 410, and the other end of the second diagonal rod 415 is slidably connected to the inner wall of the slide groove 416. One end of a first diagonal rod 414 is rotatably connected to the inner wall of the top frame 410, and the other end of the bottom frame 412 is rotatably connected to the bottom frame 412. The inner wall of frame 2 is provided with positioning pin 411 rotatably connected to the inner wall of diagonal bar 415 and diagonal bar 414, bottom beam 413 fixedly connected to the inner wall of bottom frame 412, crossbar 409 fixedly connected to the inner wall of diagonal bar 414, one end of cylinder 408 rotatably connected to the outer wall of bottom beam 413, the other end of cylinder 408 rotatably connected to the outer wall of crossbar 409, brake pin 404 slidably connected to the inner wall of housing 1, and anti-collision plate 401 is made of elastic material.

[0017] Working principle: When the device is moved, its height may obstruct the operator's view and cause it to collide with obstacles. The impact force drives the anti-collision plate 401 to retract inward and compress the stress relief spring 403 along the limit of the stress relief column 402, thereby dissipating the impact force. When the anti-collision plate 401 retracts inward, it drives the brake column 404 to move downward. The brake column 404 drives the brake plate 405 to move downward, so that the brake plate 405 contacts the ground and generates friction, stopping the device from moving and avoiding greater damage. When the device is moved to the designated position, the start cylinder 408 drives the crossbar 409 to move upward. The upward movement of the crossbar 409 drives the diagonal bar 415 to move towards the center along the fixed block 406. As the diagonal bar 415 moves towards the center, it drives the bottom frame 412 to move downward and contact the ground under the limit of the top housing 1, thereby raising the device and stopping its movement, preventing displacement of the device during operation.
