As shown in fig. 2, the camera module 2 may be mounted in a vehicle body 200. The utility model discloses a tire detecting system 100 is based on the visual detection principle, compares through the deformation situation of record tire 6 and with original surface condition to and through resource support such as database, thereby whether quick judgement tire 6 is in normal operating condition, whether have limit operating condition and whether necessary maintain or change.

It should be noted that the photographing module 2 includes a first shielding mechanism 31 and the camera 23, wherein the first shielding mechanism 31 can protect the camera 23 and provide an installation space. As shown in fig. 1, the first shielding mechanism 31 is formed with an installation cavity, the camera 23 is installed in the installation cavity of the first shielding mechanism 31, and the camera 23 can move in the installation cavity, such as the camera 23 extends out of the installation cavity when working and retracts into the installation cavity when not working. Wherein images of the tyre 6 in the non-deformed region a and/or the deformed region B can be taken when the camera 23 is extended from the mounting and operated.

And the tire detection system 100 further comprises a control module 1, the control module 1 is used for receiving the data information of the shooting module 2 and performing comparative analysis, so as to judge whether the tire 6 is in a normal working state, if not, a driver can be prompted and the vehicle can be intervened to perform safety control, and the control module 1 can also be used for driving some components to work.

It can be understood that the first shielding mechanism 31 can protect the corresponding camera 23 and provide an installation space, and can provide a driving force for the camera 23, so that the camera 23 can make a telescopic reciprocating motion in the installation cavity. And the shooting module 2 can detect the change of the surface of the tire 6 at any time, and can shoot the deformation condition of the tire 6 or the material under different conditions in various road conditions, weather conditions and the like, so as to provide comprehensive data parameters for the control module 1, and further judge the use state of the tire 6 in some road sections or in some weather and determine whether the driving risk exists or not during driving under the condition of monitoring the condition of the tire 6.

Thus, when the control module 1 receives the data collected from the photographing module 2, it is determined whether the deformation amount of the tire 6 has reached the shape limit or the material limit of the tire 6 or the tire rubber by comparing the deformation amounts of the tires 6, so that the driver can be reminded to perform the safety control.

When camera 23 contracts to the installation cavity, the installation cavity can play the effect of protection and sheltering from to camera 23, and shoot module 2's simple structure, convenient to use.

In some embodiments, the first shielding mechanism 31 includes a mounting shell, a driving member 311 and a resetting member 312. Wherein, the installation shell is formed with the installation cavity, driving piece 311 is used for driving camera 23 withdraws to in the installation cavity, reset piece 312 is used for driving camera 23 is followed the installation cavity stretches out.

It will be appreciated that when it is desired to switch the first blocking mechanism 31 to the open position, as shown in fig. 4, power provided by the reset member 312 pulls the camera 23 out of the mounting cavity until the reset member 312 returns to the natural extended position, at which time the camera 23 is fully extended out of the mounting cavity. When the first shielding mechanism 31 needs to be switched to the closed state, the driving member 311 provides power to pull the camera 23 to retract into the installation cavity, and meanwhile, the driving member 311 also compresses the resetting member 312 to elastically deform the resetting member so as to generate elastic force, thereby providing driving force for pulling the camera 23 when the first shielding mechanism 31 is switched to the open state next time.

It will be appreciated that the shutter can be caused to selectively extend and retract the camera head 23 by operation of the first shutter mechanism 31. If the camera 23 does not work, the first shielding mechanism 31 can retract the camera 23 into the mounting cavity, so that objects such as dust and dirt are prevented from polluting the lens of the camera 23, and poor shooting effect is avoided; and, some rubble or object that drive because of tire 6 rotates lead to the circumstances such as colliding with to camera 23, from this, through the shielding effect of first shielding mechanism 31, can protect camera 23 not receive damage and pollution, improve camera 23's life. Similarly, when the camera 23 is required to shoot, the first shielding mechanism 31 can provide driving force for the camera 23, so that the camera 23 can extend out of the mounting cavity, and can provide supporting force for the camera 23, so that the camera 23 can shoot stably, and the working condition of normal shooting can be entered.

In some embodiments, both driving member 311 and reset member 312 are mounted in the mounting cavity, i.e. the mounting shell can also provide a mounting space for driving member 311 and reset member 312. Specifically, the output end of driving element 311 is connected to camera 23, one end of resetting element 312 is fixed in the mounting cavity, and the other end is connected to resetting element 312.

It should be noted that, as shown in fig. 3, the mounting shell may be disposed on the vehicle body 200, and the driving element 311 and the resetting element 312 are both located in the mounting cavity of the mounting shell, and the driving element 311 and the resetting element 312 may be disposed on the same horizontal plane. Wherein, drive piece 311 and the one end of installing the shell relatively fixed and being in the installation intracavity, reset piece 312 and connect between drive piece 311 and camera 23, and the one end that camera 23 deviates from reset piece 312 is located the other end of installation intracavity. As shown in fig. 3 and 4, driving member 311 is located on the left side of resetting member 312, camera 23 is located on the right side of resetting member 312, driving member 311 can drive camera 23 to move towards the left side, so that camera 23 can move into the mounting cavity, and resetting member 312 can drive camera 23 to move towards the right side, so that camera 23 can move out of the mounting cavity.

In some embodiments, the output end of the driving member 311 is provided with a driving shaft, the driving shaft is provided with a retractable traction member 313, one end of the traction member 313, which is away from the driving member 311, is connected with the camera 23, and the resetting member 312 is sleeved outside the traction member 313.

As shown in fig. 3 and 4, the left end of the pulling member 313 is connected to the driving shaft of the driving member 311, the right end of the pulling member 313 is connected to the left side surface of the camera 23, that is, the driving member 311 is located on the left side of the pulling member 313, the camera 23 is located on the right side of the pulling member 313, when the driving shaft of the driving member 311 rotates, the pulling member 313 receives a driving force to move toward one end of the driving shaft and wind around the driving shaft, and the camera 23 is connected to the pulling member 313, so that the pulling member 313 drives the camera 23 to retract toward the installation cavity.

The pulling member 313 may be designed as a flexible member, for example, the pulling member 313 may be a flexible member such as a rope or a cloth, so that the pulling member 313 can be wound around the driving shaft of the driving member 311 by its own characteristics. Therefore, the output shaft of the driving piece 311 can rotate, the traction piece 313 is wound, and the camera 23 is effectively driven.

Therefore, the position of the camera 23 is adjusted by the driving force of the driving member 311 or the reset member 312 to flexibly shield the camera, thereby realizing selective shielding of the camera 23 by the first shielding mechanism 31.

And, a starting device may be disposed in the cockpit and electrically connected to the control module 1, so that the control module 1 may control the operation of the driving member 311 by opening or closing the starting device. If the starting device can be set as a switch button which is started by one key and is positioned in the cockpit, the first shielding mechanism 31 can be operated by the starting device when the shooting function of the camera 23 is needed, and the device is simple in structure and convenient to operate.

In some embodiments, one end of the reset element 312 is fixed to the main body of the driving element 311, and the other end is fixedly connected to the camera 23.

It should be noted that the driving member 311 may be configured as a driving motor, and the reset member 312 may be configured as a spring, wherein the driving member 311 is fixedly installed in the mounting case. One end of the spring is connected to the driving member 311, the other end of the spring is connected to the camera 23, and the spring can elastically press between the driving member 311 and the camera 23.

It will be appreciated that the return member 312 and the traction member 313 are mounted between the drive member 311 and the camera head 23, i.e. in a specific implementation, when the drive motor is rotated, the traction member 313 can be driven to wind on the motor shaft, causing the spring to be compressed and the camera head 23 connected thereto to move into the mounting cavity. And, when driving motor does not rotate, the spring is not received pressure elasticity extension, drives camera 23 and extends outside the installation cavity.

In other words, since the reset piece 312 and the pulling piece 313 are both connected between the driving piece 311 and the camera 23, it can be ensured that the reset piece 312 and the driving piece 311 provide driving force to the camera 23, so that the camera 23 can be effectively extended or retracted from the mounting cavity, and the camera 23 can be effectively protected or enter a normal working state.

In some embodiments, a first sliding portion 315 is disposed in the mounting cavity, and the camera 23 is provided with a second sliding portion 315, wherein the first sliding portion 315 is in sliding fit with the second sliding portion 315.

It should be noted that the first sliding portion 315 may be configured as a sliding rail, the second sliding portion 315 may be configured as a sliding chute, and the sliding rail and the sliding chute can be slidably engaged. That is to say, be provided with the slide rail in the installation cavity, and be provided with the spout structure at camera 23 for the slide rail in the installation cavity can cooperate with the spout on camera 23.

From this, realize the removal of camera 23 in the installation through mutually supporting of slide rail and spout, can reduce the degree of wear of camera 23 in the removal in-process through slide rail and spout, reduce camera 23's movement resistance, and can protect camera 23 to a certain extent.

In some embodiments, the first shielding mechanism 31 further includes a blocking plate 314. It should be noted that the blocking plate 314 may be configured as a rectangular square plate, and the size of the square plate is larger than the size of the open opening of the mounting cavity. And can be arranged on the outer side of the vehicle body through structures such as a spring hinge and the like, namely arranged at the opening of the installation cavity. It can be understood that, in a specific implementation, in the process that the camera 23 is driven to the outside of the mounting cavity by the reset piece 312, the camera passes through the opening of the mounting cavity, abuts against the blocking plate 314 and pushes the blocking plate 314 open, so as to completely extend out of the mounting cavity, wherein the blocking plate 314 can be kept fixed under the action of the spring hinge after being pushed open. When the camera 23 is driven by the driving member 311 and retracted into the mounting cavity, the blocking plate 314 automatically covers the opening of the mounting cavity under the action of the spring hinge when the camera 23 is fully retracted into the mounting cavity.

Therefore, the arrangement of the blocking plate 314 can further protect the camera 23 from being polluted, and the overall attractiveness of the vehicle 1000 is improved to some extent, so that the consistency of the shielding mechanism and the structure and color of the vehicle body is realized.

In some embodiments, the photographing modules 2 are two groups, two groups of photographing modules 2 are spaced apart along the circumferential direction of the tire 6 and are located outside the tire 6, the camera 23 of one group of photographing modules 2 of the two groups of photographing modules 2 is used for photographing the image of the tire 6 in the non-deformation region a, and the camera 23 of the other group of photographing modules 2 is used for photographing the image of the tire 6 in the deformation region B.

It should be noted that, as shown in fig. 1 and fig. 2, the two groups of shooting modules 2 are a first shooting module 21 and a second shooting module 22, and both the first shooting module 21 and the second shooting module 22 include a first shielding mechanism 31 and a camera 23, and the first shooting module 21 and the second shooting module 22 are circumferentially distributed at intervals outside the tire 6, for example, the first shooting module 21 may be disposed right above the tire 6, and the second shooting module 22 may be disposed obliquely above the tire 6.

The camera 23 of the first photographing module 21 is configured to photograph an image of the tire 6 in a non-deformation area a, the non-deformation area a may present an initial surface state of the tire 6, that is, the first photographing module 21 may be configured to photograph the initial surface state of the tire 6, the camera 23 of the second photographing module 22 is configured to photograph an image of the tire 6 in a deformation area B, and the deformation area B may present a state of the tire 6 when the tire 6 is under a maximum stress, that is, the second photographing module 22 may be configured to photograph an image of an area where the tire 6 is deformed during or after the tire 6 is running.

Thus, when the first photographing module 21 and the second photographing module 22 are disposed at different positions, the surface condition of the tire 6 photographed is different. By comparing the surface variables and with the support of the data in the database, whether the tire 6 is in a normal working state, whether an extreme working state exists, whether travel maintenance or replacement is necessary, and the like can be quickly judged, so that the safety of the lives and properties of the driver can be further protected.

In some embodiments, one set of camera modules 2 is located directly above the tire 6 and the corresponding camera 23 is shooting towards the upper part of the tire 6, and the other set of camera modules 2 is located diagonally above the tire 6 and the corresponding camera 23 is shooting towards the lower part of the tire 6 and the position where it contacts with the road surface. Note that, as shown in fig. 1, the non-deformation region a is at the upper end of the tire 6, and the amount of deformation of the tire 6 is small. The deformation region B is located where the tire 6 contacts the ground, and the amount of deformation of the tire 6 is large. That is, the first photographing module 21 is disposed right above and can photograph the tire image of the initial surface state of the tire 6, and the second photographing module 22 is disposed diagonally above and can photograph the tire image of the deformation of the contact portion of the tire 6 with the ground.

It can be understood that the photographed data information is photographed to be directly above the tire 6 with a smaller amount of deformation and the photographed data information is photographed to be directly below the tire 6 with a larger amount of deformation, so as to determine whether the state of the tire 6 is in a normal state, and thus determine whether to remind the driver and control the safe driving of the vehicle.

In other embodiments, further comprising: the mechanical arm is connected with the shooting module 2 and used for driving the shooting module 2 to be switched between a first position and a second position, and the camera 23 of the shooting module 2 is used for shooting the image of the non-deformation area A at the first position and used for shooting the image of the deformation area B at the second position.

In another embodiment of the present invention, a mechanical arm is connected to the driving member 311, so that the driving member 311 can drive the mechanical arm to move. And the mechanical arm is also connected with a shooting module 2. That is, a robot arm is connected in series between the driving member 311 and the photographing module 2, and the driving member 311 may be fixed to the vehicle body 200. The first position is a non-deformed region a directly above the tire 6, and the second position is a deformed region B directly below the tire 6.

It is understood that the driving member 311 drives the mechanical arm to switch back and forth between the first position and the second position, so that the camera 23 of the camera module 2 can shoot back and forth between the first position and the second position. For example, the robot arm is moved to make the camera 23 shoot the first position, and then the robot arm is moved again to make the camera 23 shoot the second position. Therefore, the shooting module 2 can be moved by moving the mechanical arm, the shooting module 2 can shoot the surfaces of different areas of the tire 6, namely shooting of the initial state of the tire 6 and shooting of the deformation state of the tire 6 in running are completed, the surface deformation state of the tire 6 is analyzed, whether the tire 6 can work normally or not is judged, and the mechanical arm is used, the shooting module 2 can be flexibly used for shooting in different positions, namely not only the deformation area and the non-deformation area of the tire 6 can be shot, but also the shooting module 2 can be used for shooting the positions of a hub and the like and analyzing whether the positions are in the normal state or not, so that the action range of the shooting module 2 is wider.

In some embodiments, the tire inspection system 100 further comprises: the spraying device 4 is electrically connected with the control module 1, and the control module 1 is used for controlling the spraying device 4 to spray detection points on the tire 6. It can be understood that the shooting module 2 is used for shooting the deformation amount of the tire 6, and it is difficult to directly observe the deformation amount with naked eyes on the tire 6 with little surface shape difference, so the spraying device 4 is introduced in the present embodiment, so that the observable shape of the deformation amount of the surface of the tire 6 is more specific and clearly obvious. If the spraying can be performed at different time periods and different driving states, the deformation degree of the tire 6 can be further judged according to the obtained change degree of the spraying shape.

The spraying device 4 is electrically connected with the control module 1, so that the rapidity of starting the spraying device 4 and spraying the tire 6 can be ensured, the spraying device 4 can be directly controlled to work through the control module 1, the operation is convenient, and the effect is obvious. Therefore, the tire 6 can be sprayed by the spraying device 4 in the running process of the vehicle 1000, so that the deformation of the tire 6 can be observed more obviously and specifically, and the parameters such as the limit degree of the calculated material and the like and the result of comparing the original tire 6 condition are more accurate when the control module 1 is used for analyzing the tire 6 condition, so that the driving safety is improved.

In some embodiments, the spray coating device 4 comprises: the spraying device comprises a spraying liquid storage tank 41, a cleaning liquid storage tank 42 and a spraying piece 43, wherein the spraying liquid storage tank 41 and the cleaning liquid storage tank 42 are selectively communicated with the spraying piece 43, and the spraying piece 43 is used for spraying a detection point or cleaning the detection point.

It should be noted that the spray reservoir 41 is used for storing spray paint, the cleaning reservoir 42 is used for storing detergent or cleaning water, and the spray member 43 may include a spray head. The spraying device 4 further comprises a vacuum pump 44, the vacuum pump 44 is connected with the spraying liquid storage tank 41 and the cleaning liquid storage tank 42, the vacuum pump 44 can be selectively communicated with the spraying liquid storage tank 41 or the cleaning liquid storage tank 42 through a control valve, and the vacuum pump 44 is connected with the spraying piece 43 through a hose 45.

And the spraying device 4 further comprises a casing 46, the spraying liquid storage tank 41, the cleaning liquid storage tank 42, the spraying piece 43, the vacuum pump 44 and the hose 45 are all arranged in the casing 46 of the spraying device 4, and the spray head of the spraying piece 43 is exposed out of the casing 46.

In a specific implementation, when the spraying reservoir 41 or the cleaning reservoir 42 is used, the liquid for spraying the reservoir 41 or the cleaning reservoir 42 is fed into the vacuum pump 44, and the vacuum pump 44 turns the liquid into high-pressure liquid and emits the high-pressure liquid through the spraying member 43, so as to achieve the effect of spraying or washing the surface of the tire 6, that is, the surface of the tire 6 can be sprayed with paint or dirt on the surface of the tire 6 can be peeled off and washed clean.

It will be appreciated that the spraying or cleaning of the sprayed monitoring points by the spraying member 43 can reduce the calculation error caused when the tire 6 is seriously deformed or does not meet the measurement requirements during the continuous running process.

Among them, one example in the present embodiment is that the image sprayed by the spraying device 4 on the surface of the tire 6 is a circular dot, and the error range in which the size of the dot exceeds the initial spraying point ± 0.1mm is satisfied. However, the shape of the image sprayed on the surface of the tire 6 by the spraying device 4 is not limited in this embodiment, and may be set according to the shape of the tire 6 or personal preference, for example, the spraying shape may be a square point or other irregular image.

And, the vacuum pump 44 included in this embodiment can selectively clean the liquid in the liquid storage tank 42 through the control valve, so that the spraying member 43 can achieve better spraying and cleaning effects on the tire 6.

In practical implementation, the spraying error of the spraying device 4 of the embodiment is different in different driving states of the vehicle 1000, that is, the selection of the spraying timing affects the change of the detection accuracy, for example, when the vehicle 1000 stops, the spraying effect is the best, and when the vehicle stops, the surface of the tire 6 can be sprayed with the mark points first; if spraying is required during the running process, a certain requirement for the precision of the spraying equipment, namely the speed of the vehicle 1000, can be determined according to the precision of the spraying device 4 and the requirement of the detection system. For example, the error range of the point sprayed at 70km/h can be +/-0.1 mm, the requirement that the precision range of a detection system can be +/-0.2 mm is met, and the like.

A specific variation may be as shown in fig. 5, i.e. a flow image of the tire 6 at each stage after the spraying device 4 sprays the surface of the tire 6.
