Description

Technical Field

[0001] The present invention relates to the technical field of vehicle monitoring, and in particular to a vehicle-mounted panoramic video recording system and a vehicle comprising the system. Background Art

[0002] The existing vehicle-mounted panoramic camera system is mainly installed on the top of the vehicle. For passenger cars or family cars, the vehicle-mounted panoramic camera system has an upright lifting type, but this panoramic camera system is often limited in height. If the vehicle body is large, it is impossible to capture the scene behind the rear of the vehicle. In addition, the lifting structure of the panoramic camera system in the prior art often uses a simple lifting rod, which cannot achieve a greater height displacement.

[0003] In order to solve the problem of height limitation, the existing vehicle-mounted panoramic camera system adopts a lodging mechanism, such as Figure 1 As shown, its installation layout on the vehicle is as follows Figure 2 As shown, the inverted rod performs a flipping motion around the center of the base to make the camera stand upright. The entire structure is designed as a cantilever beam. During the driving of the vehicle, the camera is laid down and placed horizontally on the top of the vehicle to prevent the excessively high recording system from interfering with the signs or tree branches on the road. However, the entire structure will vibrate due to the ups and downs of the vehicle, causing alternating stress to the transmission mechanism in the base, accelerating fatigue damage to the equipment. Moreover, the area swept during the erection of the camera is very large, the possibility of danger increases, and interference problems are prone to occur. And when the equipment fails, maintenance personnel can only repair it by going up to the roof, which increases the risk to personnel safety and is not convenient for maintenance. In order to ensure the shooting range of the panoramic recording system, reduce the movement area of ​​the mechanism, avoid the risk of damage caused by the cantilever beam form, and reduce the risk to personnel safety, the present invention is proposed.

[0056] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0057] Example 1

[0058] A specific embodiment of the present invention, as Figure 3 and Figure 4 As shown, a vehicle-mounted panoramic camera system 10 is disclosed, comprising a support mechanism 100, a power mechanism 200, a motion mechanism 300, a cable assembly, and a panoramic camera device 400. The vehicle-mounted panoramic camera system 10 descends and remains at the lowest point during the process from when the vehicle 1 starts to drive to when it stops. After the vehicle 1 stops, if the vehicle-mounted panoramic camera system 10 is to be used, it can be electrically raised to the highest point and kept running, and is mainly used for monitoring the surrounding environment of the vehicle 1 after the vehicle 1 stops.

[0059] The supporting mechanism 100 includes a fixing seat 110 , a housing 120 , an end cover 130 , a cover plate 140 and an adapter seat 150 .

[0060] See also Figure 4 , Figure 5 as well as Fig.10The fixing seat 110 is a frame structure for fixing and supporting the power mechanism 200, the motion mechanism 300 and the panoramic camera device 400. The fixing seat 110 includes a bottom plate 111, a first side plate 112, a second side plate 113 and a top plate 114.

[0061] See attached Figure 3-Figure 6 The housing 120 is a quadrangular cylindrical body, and the end of one end of the housing 120 is fixedly arranged on the upper surface of the top plate 114 of the fixing seat 110. The end cover 130 is fixedly arranged on the end of the other end of the housing 120. The adapter 150 is fixedly arranged on the side of the other end of the housing 120.

[0062] The power mechanism 200 includes a motor 210, a reducer unit 220 and a screw nut unit 230. Figure 4-Figure 6 The motor 210 is fixedly arranged below the fixing seat 110, and the output shaft of the motor 210 extends upward into the fixing seat 110. The reducer unit 220 is arranged in the fixing seat 110, and the output shaft of the motor 210 is transmission-connected with the input end of the reducer unit 220. The lead screw and nut unit 230 is arranged above the fixing seat 110, and the lead screw 231 of the lead screw and nut unit 230 is transmission-connected with the output end of the reducer unit 220. And the lead screw and nut unit 230 is located inside the housing 120. With such arrangement, the motor 210 can drive the lead screw 231 to rotate through the reducer unit 220, thereby driving the nut 232 to move up and down along the lead screw 231.

[0063] See attached Figure 4-Figure 5 The motion mechanism 300 includes a moving rod 310, which is a quadrangular prism hollow structure with a flange, and is sleeved outside the lead screw 231 of the lead screw nut unit 230. The moving rod 310 is screwed to the nut 232 of the lead screw nut unit 230. The quadrangular prism hollow structure is used to facilitate the installation of other components such as sliders and cables on its side.

[0064] By such arrangement, the nut 232 can move the moving rod 310 up and down when it moves up and down.

[0065] See attached Figure 4-Figure 6 as well as Fig.11 The cable assembly includes a cable, a first threading tube 170, a drag chain 180 and a second threading tube 320. The cable is connected from the bottom of the housing 120, passes through the first threading tube 170, the drag chain 180 and the second threading tube 320 in sequence, and is connected to the panoramic camera device 400.

[0066] The length of the first threading tube 170 is less than or equal to half the height of the housing 120, and the first threading tube 170 is fixedly arranged at the lower half of the housing 120 and extends in the vertical direction. The length of the second threading tube 320 is less than or equal to the length of the moving rod 310, and the second threading tube 320 is fixedly arranged inside the moving rod 310 and extends in the vertical direction. The fixed end of the drag chain 180 is connected to the top end of the first threading tube 170, and the moving end of the drag chain 180 is connected to the bottom end of the second threading tube 320, wherein the drag chain 180 is a flexible drag chain.

[0067] The first threading tube 170 is preferably a hollow round tube, which is fixedly arranged on a side surface inside the housing 120, one end of which is fixedly connected to the bottom of the housing 120, and the other end of which is fixedly connected to the middle of the housing 120. The fixed end of the drag chain 180 is fixedly arranged in the middle of the housing 120 and docked with the first threading tube 170. The movable end of the drag chain 180 is fixedly arranged at the bottom of the movable rod 310.

[0068] The second threading tube 320 is preferably a hollow round tube. The second threading tube 320 is fixedly disposed at a corner inside the moving rod 310 and extends from the top of the moving rod 310 to the bottom of the moving rod 310 .

[0069] The panoramic camera device 400 is fixedly arranged on the top of the moving rod 310. Thus, the panoramic camera device 400 can be driven by the moving rod 310 to move up and down.

[0070] See also Fig. 9 The panoramic camera device 400 includes a housing 410, a switch 420, a cover 430 and a camera module 440. The switch 420 is fixedly arranged in the middle of the housing 410, and a plurality of camera modules 440, preferably 6, are provided, which are respectively fixedly arranged at the six inner surfaces of the housing 410. The camera module 440 is connected to the switch 420 through a cable, and the switch 420 is connected to the external communication through a connector. The cover 430 is fixedly arranged on the top of the housing 410. The images of the 6 camera modules 440 are spliced ​​into a 360° panoramic image through software. The camera modules 440 can also be other quantities, such as 4, or 8, etc. The lenses of the multiple camera modules 440 are all tilted downward, and the fields of view of two adjacent ones of the multiple camera modules 440 have overlapping parts.

[0071] The cable is routed from the center connector at the bottom of the panoramic camera device 400, reaches the bottom of the moving rod 310 through the second threading tube 320, leads out from the opening above the nut 232 of the screw nut unit 230 to the moving end of the drag chain 180 on the moving rod 310, reaches the fixed end of the drag chain 180 in the middle of the outer shell 120 through the drag chain 180, and then reaches the bottom of the outer shell 120 through the first threading tube 170, and leads out a connector from the bottom of the outer shell 120 for use in image transmission between the panoramic camera device 400 and other equipment.

[0072] The signals of the multiple cameras are processed by the switch 420 in the panoramic camera device 400 and then transmitted via a connector.

[0073] The vehicle-mounted panoramic video recording system of this embodiment adopts a lifting structure to reduce the dangerous area of ​​the panoramic camera's falling mechanism from a fan-shaped area to a cylindrical area above the camera component, thereby reducing the probability of interference. The structural features of this embodiment are compact, the technology is mature, and the cantilever beam structure is abandoned to improve the vibration resistance. In addition, since the vehicle-mounted panoramic video recording system of this embodiment adopts a lifting structure, all camera lenses are always placed obliquely downward, which improves the environment in which the camera is located, reduces the variability in the life of the camera, and avoids the harsh environment in which the camera originally designed to rush into the sky after falling over is located, resulting in early scrapping.

[0074] Example 2

[0075] Based on Example 1, see Figure 4 , Figure 6 The reducer unit 220 includes a first gear 221, a second gear 222, a third gear 223 and a fourth gear 224, wherein the first gear 221 is arranged on the bottom plate 111 of the fixed seat 110 and is drivingly connected to the output shaft of the motor 210; the second gear 222 is arranged on the first side plate 112 of the fixed seat 110, and the third gear 223 is arranged on the second side plate 113 of the fixed seat 110, the first side plate 112 and the second side plate 113 are arranged opposite to each other, and the second gear 222 and the third gear 223 are both meshed with the first gear 221; the fourth gear 224 is arranged on the top plate 114 of the fixed seat 110, and the fourth gear 224 is respectively meshed with the second gear 222 and the third gear 223; the shaft of the fourth gear 224 is drivingly connected to the lead screw 231.

[0076] The first gear 221 , the second gear 222 , the third gear 223 and the fourth gear 224 are all disposed on the fixing seat 110 via tapered roller bearings 116 .

[0077] The structure of the reducer unit 220 is similar to that of a differential, and the transmission ratio is 1:1. A mounting through hole 115 is provided on the bottom plate 111 of the fixed seat 110, and a tapered roller bearing 116 is provided in the mounting through hole 115. The first gear 221 is arranged on the fixed seat 110 through the tapered roller bearing 116, and the motor 210 is installed with the first gear 221 through a key, and is limited by a retaining ring. A mounting through hole 115 is provided on the top plate 114 of the fixed seat 110, and a tapered roller bearing 116 is provided in the mounting through hole 115. The fourth gear 224 is arranged on the fixed seat 110 through the tapered roller bearing 116, and the lead screw 231 is installed with the fourth gear 224 through a key, and is limited by a retaining ring. In this structure, the first gear 221 is driven to rotate by the motor 210, and the rotation is transmitted to the fourth gear 224 to drive the lead screw 231 to rotate.

[0078] The reducer unit 220 is arranged between the output shaft of the motor 210 and the lead screw 231. When the equipment fails and cannot be electrically controlled to lift, the second gear 222 or the third gear 223 can be driven by rotating the drive head 117 in the reducer unit 220, thereby driving the lead screw 231 to rotate to achieve manual lifting. The second gear 222 and the third gear 223 can be adapted to vehicles with different layouts, and can be installed on the left side of the vehicle or on the right side of the vehicle. Regardless of the layout, there will be a drive head 117 for maintenance personnel to operate. The symmetrical design is also conducive to uniform force on the gears and is not prone to unbalanced loads.

[0079] Furthermore, a mounting through hole 115 is provided on the first side plate 112 and / or the second side plate 113 of the fixed seat 110, a tapered roller bearing 116 is provided in the mounting through hole 115, the axis of the second gear 222 and / or the third gear 223 passes through the tapered roller bearing 116 and extends outside the fixed seat 110, and a drive head 117 is provided at the end of the axis of the second gear 222 and / or the third gear 223.

[0080] Through the above arrangement, when the motor 210 fails, a wrench can be used to drive the drive head 117 to rotate the second gear 222 or the third gear 223, so that the motion mechanism rises or falls.

[0081] Example 3

[0082] Based on the above embodiment 1 or 2, see Figure 4 , Figure 7 In order to make the movement of the motion mechanism 300 more stable, the motion mechanism 300 further includes a guide rail slider unit 160, which includes a guide rail 161, which is fixedly arranged at one side of the housing 120. It also includes a slider 162, which is fixedly arranged at the bottom of the moving rod 310 and is also sleeved on the guide rail 161.

[0083] Through the above arrangement, when the moving rod 310 moves up and down, the slider 162 also moves up and down along the guide rail 161, so that the guide rail 161 can guide the moving rod 310 and make the movement of the moving rod 310 more stable. In order to further improve the guiding effect, multiple guide rail slider units 160 can also be provided.

[0084] Further, see Figure 8 A flange 311 is fixedly provided at the bottom of the moving rod 310 , and a threaded hole is processed on the flange 311 ; an external thread is processed on the flange of the nut 232 , and the moving rod 310 is threadedly connected to the nut 232 through the flange 311 .

[0085] Through the above arrangement, the connection between the nut 232 and the moving rod 310 is stable and reliable.

[0086] Furthermore, the first gear 221, the second gear 222, the third gear 223 and the fourth gear 224 are all straight bevel gears. The straight bevel gear transmission has the characteristics of transmitting large power and torque, reliable operation, stable gear meshing, and low noise.

[0087] Furthermore, the relationship between the stroke L of the moving rod 310 and the height H of the vehicle is: H / 3≤L≤H / 2, preferably 1 m.

[0088] The travel L of the moving rod 310 is approximately equal to the distance between the panoramic camera device 400 and the top of the vehicle 1 when the moving rod 310 rises to the highest position. Through the above configuration, the vehicle-mounted panoramic camera system 10 of the present invention can be applied to large freight vehicles, and even if the vehicle is too long (12m-18m) and the cargo box is too high (3m-3.5m), panoramic camera recording around the vehicle body can be achieved.

[0089] Further, see Fig.11The cable assembly includes a first threading tube 170, a drag chain 180, and a second threading tube 320, which are arranged as a path for data transmission cables. The first threading tube 170 and the second threading tube 320 are hollow steel tubes. The first threading tube 170 is fixedly arranged in the housing 120, and extends from the bottom connector outlet position of the housing 120 to the middle of the housing 120. The second threading tube 320 is fixedly arranged in the moving rod 310, and extends from the bottom of the moving rod 310 to the top of the moving rod 310. One end of the drag chain 180 is fixedly arranged in the middle of the housing 120, and is connected to the first threading tube 170, and the other end of the drag chain 180 is fixedly arranged at the bottom of the moving rod 310, and is connected to the second threading tube 320. The drag chain 180 is a flexible structure, which can be a chain, or other structures such as a hose and a corrugated pipe. The cable passes through the first threading tube 170, the drag chain 180 and the second threading tube 320, and is fixedly installed. When the cable is lifted or lowered, it does not move relative to the first threading tube 170, the drag chain 180 and the second threading tube 320 in the length direction. When the moving rod 310 is lifted or lowered, the drag chain 180 drives this part of the cable to move. This arrangement can effectively reduce the cables exposed to the external environment, reduce the length of the moving cables, avoid the cables from getting entangled during the movement, or interfere with the movement of the moving rod, and improve the service life of the cables and the stability of the entire system operation.

[0090] Example 4

[0091] See attached Fig.10 The present invention also relates to a vehicle 1, comprising any one of the vehicle-mounted panoramic camera systems 10 of the aforementioned embodiments, wherein the vehicle 1 comprises a cab 2 and a trunk 3 which are spaced apart, and the vehicle-mounted panoramic camera system 10 is arranged between the cab 2 and the trunk 3.

[0092] Through the above arrangement, the panoramic camera system 10 can be improved from a lying type to a lifting type, and the panoramic camera system 10 can be raised to a relatively high height, and thus can be suitable for large vehicles.

[0093] Further, see Figure 10-13 In order to better fix the panoramic camera system 10, a limiting structure 21 is provided on the outer surface of one side of the cab 2 close to the rear compartment 3. The limiting structure 21 includes a first limiting portion 22 engaged with the fixing seat 110, and also includes a second limiting portion 23 fixedly engaged with the adapter 150. The first limiting portion 22 and the second limiting portion 23 can adopt conventional mechanical structures in the prior art, such as a clamping structure, a screwing structure, a welding structure, etc. Through the above arrangement, the panoramic camera system 10 can be stably fixed on the vehicle 1. During the movement of the vehicle 1, no bumps or shakes will occur, and the alternating force on the power mechanism caused by this is also avoided, thereby extending the service life of the entire system.

[0094] Furthermore, the limiting structure 21 is arranged near one side in the width direction of the vehicle. Such arrangement facilitates daily inspection and maintenance. When the vehicle-mounted panoramic camera system 10 fails and the panoramic camera device 400 cannot be electrically raised or lowered, maintenance personnel can operate the driving head 117 of the second gear 222 or the third gear 223 in the reducer unit 220 nearby without climbing the vehicle, and manually raise or lower the panoramic camera device 400, thereby reducing emergency response time, reducing the operation of climbing operations such as getting on the vehicle, and reducing the probability of risks to personnel.

[0095] Compared with the prior art, the vehicle-mounted panoramic video recording system provided in this embodiment is arranged between the cab and the rear compartment, which can reduce the installation space occupied by the whole vehicle product, and convert the original horizontal occupied space on the roof into vertical occupied space, and the vacated plane space can be used to install other equipment.

[0096] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
