For example, the cooling module 2 may be adaptively arranged according to the type of the selected cooling medium. Specifically, air may be selected as the cooling medium, and in this case, a device capable of driving air flow, such as an air conditioner or a fan 211, may be selected as the driving member 21; a cooling liquid may be used as the cooling medium, and in this case, a device capable of driving the flow of the cooling liquid may be used as the driving member 21, for example, a water pump or the like. In the case where the cooling medium is air and the driving element 21 is an air conditioner, a fan 211, or the like, the imaging element 1 may be provided in a path along which the driving element 21 drives the air, so that the air flow near the imaging element 1 can be accelerated, and the imaging element 1 can be cooled.

In addition, in the embodiment of the present utility model, there are various choices for the position where the photovoltaic power module 3 is provided on the vehicle 4, as long as the photovoltaic power module 3 can be sensitized. However, in view of the capability and efficiency of the photovoltaic power module 3 to generate electric power, the photovoltaic power module 3 may be disposed at a position where it can directly sense light, for example, on the front windshield 41 or the rear windshield, or on the outer surface of the vehicle 4.

In this way, in the vehicle-mounted image pickup system provided by the embodiment of the utility model, the photovoltaic power supply assembly 3 is arranged to provide power for the driving piece 21, so that the driving piece 21 drives the cooling medium to flow so as to exchange heat with the image pickup piece 1, and the purpose of cooling the image pickup piece 1 is achieved. Therefore, the cooling piece of the vehicle-mounted imaging system provided by the embodiment of the utility model does not use the electric energy of the vehicle 4, the electric system of the vehicle-mounted imaging system provided by the embodiment of the utility model can be isolated from the electric system of the vehicle 4, and the electric load of the vehicle 4 can be reduced, so that the influence on the vehicle 4 caused by the vehicle-mounted imaging system provided by the embodiment of the utility model when in use can be reduced. Meanwhile, in the embodiment of the utility model, no mechanical connection structure exists in the process of generating electric energy by using the photovoltaic power module 3, so that the vehicle-mounted camera system provided by the embodiment of the utility model has a simple structure.

The cooling medium is easy to obtain air, has little influence on the environment, and does not need facilities such as a storage water tank or a circulation pipeline compared with the cooling liquid, so that the cooling component 2 of the vehicle-mounted imaging system provided by the embodiment of the utility model has simple structure and strong adaptability.

Specifically, referring to fig. 1, 2 and 4, in some embodiments of the present utility model, the driving member 21 is provided as a fan 211, and the image pickup member 1 is provided on an air outlet path of the fan 211. The fan 211 is generally provided with blades, a housing, an air inlet, and an air outlet, and when the blades of the fan 211 rotate, the blades drive air to flow from the air inlet to the air outlet. In the embodiment of the utility model, the image pickup element 1 is arranged on the air outlet path of the fan 211, so that the air flow flowing through the air outlet of the fan 211 can be utilized to dissipate heat of the image pickup element 1, and the purpose of cooling the image pickup element 1 is achieved.

In the embodiment of the present utility model, the type of the fan 211 is not limited, and an axial fan, a centrifugal fan, a mixed flow fan, a cross flow fan, or the like may be used as an example, which is not limited in the embodiment of the present utility model. In addition, there are various options for setting the image pickup element 1 on the air outlet path of the fan 211, and for example, the image pickup element 1 may be directly set at the air outlet of the fan 211, or the image pickup element 1 may be set near the air outlet of the fan 211, so that the air flowing through the air outlet of the fan 211 flows through the image pickup element 1. In addition, an air flow channel may be provided between the air outlet of the fan 211 and the image pickup device 1, so that the air flow from the air outlet of the fan 211 flows through the image pickup device via the air flow channel, thereby dissipating heat from the image pickup device 1.

On this basis, referring to fig. 1 and 2, in order to facilitate the installation of the image pickup element 1 and the fan 211, in some embodiments of the present utility model, the vehicle-mounted image pickup system further includes a mounting bracket 5, specifically, the mounting bracket 5 may be fixedly connected to the vehicle body, and then the image pickup element 1 and the fan 211 may be fixedly connected to the mounting bracket 5, so that the mounting bracket 5 may serve as a medium for fixedly connecting the image pickup element 1 and the fan 211 to the vehicle body 4, and only the mounting bracket 5 may be fixedly connected to the vehicle body, so that the number of connection structures between the vehicle-mounted image pickup system and the vehicle body provided in the embodiments of the present utility model may be reduced.

It should be noted that, in the embodiment of the present utility model, the manner in which the mounting bracket 5 is fixedly connected to the vehicle body is not limited, and, by way of example, referring to fig. 1 and 2, the mounting bracket 5 may be fixedly connected to the vehicle body by means of the fastener 8. In addition, the mounting bracket 5 may be fixedly connected to the vehicle body by welding or bonding. In addition, in the embodiment of the present utility model, the specific form of the mounting bracket 5 is not limited, and the mounting bracket 5 may be made of a plate-like structure, so that the image pickup element 1 may be mounted on a side of the plate-like structure corresponding to the outside of the vehicle 4, the fan 211 may be mounted on a side of the plate-like structure corresponding to the inside of the vehicle 4, and the image pickup element 1 may be located on an air outlet path of the fan 211.

In addition, referring to fig. 1 and 2, the mounting bracket 5 may be made of a box-type structure, so that an air flow passage between the fan 211 and the image pickup element 1 may be provided by using the mounting bracket 5 of the box-type structure. Specifically, the inside of the housing-type mounting bracket 5 may be hollow, and an air inlet 51 and an air outlet (not shown in the figure) are provided on the housing-type mounting bracket 5, the outlet of the fan 211 is mounted to the housing-type mounting bracket 5 corresponding to the air inlet 51, and the camera 1 is mounted to the housing-type mounting bracket 5 corresponding to the air outlet 52 for viewing angle reasons. In this way, an air flow passage between the outlet of the fan 211 and the image pickup element 1 can be formed by the hollow structure inside the housing-type mounting bracket 5. In this way, the air flow channel between the outlet of the fan 211 and the image pickup device 1 can be isolated from the external environment, so that all the air flow at the outlet of the fan 211 flows through the image pickup device 1, and the heat dissipation efficiency of the image pickup device 1 is improved.

In addition, in order to increase the angle of view of the imaging element 1, the imaging element 1 is generally disposed at a position where the vehicle body is high. Therefore, in some embodiments of the utility model, the mounting bracket 5 may be provided in the vehicle 4 at a position near the upper portion of the windshield. Further, depending on the purpose of use of the image pickup device 1, the image pickup device 1 may be provided at a position corresponding to the front of the vehicle 4 or a position corresponding to the rear of the vehicle 4, and for this purpose, the mount bracket 5 may be provided at a position of an inner upper portion of the front windshield 41 or the mount bracket 5 may be provided at a position of an inner upper portion of the rear windshield, which is not limited by the embodiment of the present utility model.

In order to enable the vehicle-mounted image pickup system provided by the embodiment of the present utility model to function more stably and more comprehensively, the number of image pickup pieces 1 may be set to at least two. Specifically, the type or number of the image pickup pieces 1 may be set according to the purpose of use of the in-vehicle image pickup system.

For example, for using the vehicle-mounted image pickup system provided by the embodiment of the present utility model for automatic driving of the vehicle 4, the calculation of the obstacle distance may be realized by using more than two image pickup devices 1 to simulate stereoscopic vision. For the vehicle-mounted image pickup system provided by the embodiment of the utility model to be used for photographing road conditions and in-vehicle conditions, two or more cameras may be mounted on the mounting bracket 5 with the lens of each image pickup element 1 directed to corresponding different positions.

For the vehicle-mounted image capturing system provided in the embodiment of the present utility model includes at least two image capturing elements 1, the number of fans 211 is also at least two, and is set in one-to-one correspondence with the image capturing elements 1. Here, the fans 211 are disposed in one-to-one correspondence with the image pickup devices 1, that is, the number of fans 211 is the same as the number of image pickup devices 1, and each fan 211 can cool the corresponding image pickup device 1. For example, two image pickup pieces 1 and two fans 211 may be provided in the manner shown in fig. 1 and 2. In addition, an air flow passage is provided between each fan 211 and all the image pickup pieces 1. In this way, each fan 211 can cool all the image pickup devices 1.

Specifically, a plurality of air pipes may be disposed at the outlet of the fan 211 to guide the air flow from the outlet of the fan 211 to each of the image pickup members 1. In addition, referring to fig. 1 and 2, the structural features of the mounting bracket 5 may also be utilized to provide an air flow path between each fan 211 and all of the image pickup pieces 1. Referring to fig. 1 and 2, two heat dissipation members and two fans 211 are described as an example, and two or more fans 211 and two or more heat dissipation members may be provided with reference to fig. 1 and 2.

For the box-type mounting bracket 5, the inside of the mounting bracket 5 may be set to be hollow, and two air flow inlets 51 and two air flow outlets 52 are provided on the box-type mounting bracket 5, the two image pickup pieces 1 are respectively mounted at the two air flow outlets 52, and the two fans 211 are respectively mounted at the two air flow inlets 51. In this way, the hollow structure inside the box-type mounting bracket 5 communicates all the air flow inlets 51 and the air flow outlets 52, which is also equivalent to forming an air flow passage between each fan 211 and all the image pickup pieces 1, each fan 211 being capable of cooling all the image pickup pieces 1.

With the above arrangement, in the vehicle-mounted image capturing system provided in the embodiment of the present utility model, even if one or some fans 211 fail and cannot normally operate, other fans 211 can cool all the image capturing pieces 1, so that the temperature of the image capturing pieces 1 is kept at a normal level, and the image capturing pieces 1 can normally operate.

In addition, in some embodiments of the present utility model, referring to fig. 1 and 4, in order to improve the cooling efficiency of the image pickup element 1, an outer case 6 is further provided at the outer periphery of the image pickup element 1 and the fan 211. In addition, the outer casing 6 can also isolate the camera 1 and the fan 211, plays a role in protecting the camera 1 and the fan 211, and can also hide the wiring harness of the camera and the fan 211 electrically connected to other devices, so that the inside of the vehicle 4 is kept neat and beautiful.

The increase in temperature of the image pickup device 1 is partly due to heat generated when the image pickup device 1 is operated, and partly due to heat transfer to the image pickup device 1 due to a high external environment temperature, so that the temperature of the image pickup device 1 is increased, particularly, a place where solar energy is directly irradiated. However, in order to make the image pickup device 1 have a large angle of view, the image pickup device 1 is generally disposed at a high position of the vehicle 4, for example, the image pickup device 1 is disposed at an upper portion inside the front windshield 41 or the rear windshield, and the temperature of the image pickup device 1 is greatly increased due to direct sunlight. For this, the outer casing 6 may be used to guide the air at the inlet of the fan 211 and the outlet of the fan 211, so that the air at the inlet of the fan 211 comes from a region where the temperature is low, and the air at the outlet of the fan 211 is far from the inlet of the fan 211. Specifically, referring to fig. 1 and 4, the outer cover 6 may be provided in an inwardly recessed structure such that a receiving chamber may be formed between the outer cover 6 and the vehicle body, and the image pickup member 1 and the fan 211 may be provided in the receiving chamber. An air inlet duct 61 and an air outlet duct 62 through which the air flow flows are provided between the outer cover 6 and the windshield.

By way of example, referring to fig. 1 and 4, by providing a gap between the outer case 6 and the vehicle body, the gap can be made to function as the air intake passage 61 and the air outlet passage 62 of the fan 211. Thus, when the fan 211 is operated, air enters the outer casing 6 through the gap corresponding to the air inlet passage 61, flows through the outer casing 6 to cool the imaging element 1, and finally flows out of the outer casing 6 through the gap corresponding to the air outlet passage 62. In addition, holes may be provided in the outer case 6 to form the air inlet passage 61 and the air outlet passage 62. The embodiment of the present utility model does not limit the specific arrangement modes of the air inlet channel 61 and the air outlet channel 62.

On this basis, in some embodiments of the present utility model, the in-vehicle image pickup system is provided at the upper portion inside the front windshield 41 or the rear windshield, so that it is possible to ensure that the image pickup member 1 has a sufficiently large visual angle. In this regard, the air intake duct 61 may be provided on the side of the front windshield 41 or the rear windshield closer to the roof, and the air outlet duct 62 may be provided on the side of the front windshield 41 or the rear windshield closer to the front hatch or the rear hatch, that is, on the side of the front windshield 41 or the rear windshield farther from the roof. Since the roof can block the direct irradiation of part of sunlight, the air temperature at the roof is low relative to the air temperature at the front windshield 41 or the rear windshield, and the air intake duct 61 is provided at a position close to the roof of the automobile, the air temperature for radiating the heat of the image pickup device 1 can be low, and the efficiency of radiating the heat of the image pickup device 1 can be improved. Meanwhile, the air outlet channel 62 is arranged at a position close to the front hatch cover or the rear hatch cover, namely, the air outlet channel 62 is arranged at a position far away from the roof, so that the air outlet channel 62 is far away from the air inlet channel 61 as far as possible, and the influence of hot air of the air outlet channel 62 on the air inlet channel 61 is reduced.

In addition, referring to fig. 3, in some embodiments of the present utility model, the in-vehicle imaging system further includes a control module 7, and in particular, the control module 7 includes a temperature measurement assembly 71 and a controller 72. Specifically, the temperature measuring assembly 71 may be thermally connected to the image pickup element 1, so that the temperature of the image pickup element 1 can be measured by the temperature measuring assembly 71. By electrically coupling the temperature measurement assembly 71 and the driving member 21 to the controller 72, the controller 72 can be caused to acquire the temperature of the image pickup member 1 through the temperature measurement assembly 71. Meanwhile, the controller 72 may be configured to control the driver 21 by presetting a relevant program or instruction to the controller 72.

Specifically, the operation of the driving assembly can be controlled according to the temperature of the image pickup element 1, and when the temperature of the image pickup element 1 is high, the controller 72 is used for controlling the driving element 21 to be in an operation state, so that the image pickup element 1 can be cooled; when the temperature of the image pickup device 1 is low, the controller 72 controls the driving device 21 to be in a stopped state. Specifically, the first preset threshold and the second preset threshold may be set to control the operation of the driving element 21, and the controller 72 controls the driving element 21 to be in an operation state when the temperature value of the image pickup element 1 is greater than or equal to the first preset threshold, and controls the driving element 21 to be in a stop operation state when the temperature value of the image pickup element 1 is less than or equal to the second preset threshold. It should be noted that the first preset threshold is greater than the second preset threshold. Illustratively, referring to FIG. 5, a logic control diagram for the driver 21 is shown. In addition, in order to prevent frequent activation of the driving element 21, the difference between the first preset threshold and the second preset threshold may be set slightly larger, specifically, may be set according to the maximum temperature value that can be tolerated during normal operation of the imaging element 1 and considering the cooling efficiency of the cooling medium on the imaging element 1.

In the embodiment of the present utility model, the arrangement of the temperature measuring unit 71 is not limited, and for example, a temperature sensor may be selected as the temperature measuring unit 71, and further, a resistive temperature sensor may be selected, or a galvanic temperature sensor may be selected. Other devices capable of measuring temperature may be used as the temperature measuring assembly 71 in the embodiment of the present utility model.

In addition, there are various arrangements for thermally connecting the temperature measuring assembly 71 to the image pickup member 1, and referring to fig. 1 and 2, for example, the temperature measuring assembly 71 may be directly contacted with the image pickup member 1 and disposed on the upper surface of the image pickup member 1, so that the temperature of the image pickup member 1 can be measured more accurately.

The controller 72 may be a programmable logic controller (Programmable Logic Controller, PLC), or may be another device having a processing function, for example, a vehicle 4 provided with a vehicle control system, or the vehicle control system may be used as the controller 72. In addition, with the development of the vehicle 4 and the vehicle control system, a plurality of sub-control systems are further provided to control the vehicle 4, for example, the vehicle control system may be divided into an intelligent cabin domain controller, a vehicle control unit, a brake integrated controller and a thermal management controller according to the specific equipment controlled by the vehicle control system, and for this purpose, one of the above controllers may be used as the controller 72 in the embodiment of the present utility model.

In order to improve the stability of the vehicle-mounted camera system provided by the embodiments of the present utility model, in some embodiments of the present utility model, the photovoltaic power module 3 includes at least two photovoltaic power components 31, the photovoltaic power components 31 are further disposed at different positions of the vehicle 4, and each photovoltaic power component 31 is electrically connected to the driving component 21 through a corresponding electrical circuit 32.

Illustratively, referring to fig. 1, a photovoltaic power module 3 including two photovoltaic power members 31 is illustrated. Specifically, two photovoltaic power supply members 31 may be provided on the left and right sides of the upper portion of the front windshield 41, respectively. In addition, two photovoltaic power supply members 31 may be provided on the left and right sides of the upper portion of the rear windshield. On this basis, one photovoltaic power supply member 31 may be provided on the front windshield 41, and the other photovoltaic power supply member 31 may be provided on the rear windshield.

The stronger the intensity of the photovoltaic power supply piece 31 irradiated by sunlight, the stronger and more stable the capability of generating electric energy, in the embodiment of the utility model, by arranging more than two photovoltaic power supply pieces 31 and arranging the photovoltaic power supply pieces 31 at different light sensing positions of the vehicle 4, one or some photovoltaic power supply pieces 31 can feel stronger intensity of the sunlight, so that the photovoltaic power supply component 3 of the vehicle-mounted image pickup system provided by the embodiment of the utility model can stably generate electric energy, thereby improving the stability of the vehicle-mounted image pickup system provided by the embodiment of the utility model. In addition, in the embodiment of the present utility model, each photovoltaic power supply element 31 is further connected to the driving element 21 through an independent electrical loop 32, so that when one or some photovoltaic power supply elements 31 fail, other photovoltaic power supply elements 31 can supply power to the driving element 21 through the independent electrical loop 32, thereby further improving the stability of the vehicle-mounted imaging system provided in the embodiment of the present utility model.

On this basis, in some embodiments of the present utility model, the vehicle-mounted image capturing system further includes a switching assembly 73, and the switching assembly 73 may be configured to turn on or off the above-described electrical circuit 32 corresponding to each of the photovoltaic power supply members 31. And the controller 72 may be further utilized to obtain parameters of each electrical circuit 32, and by electrically coupling the controller 72 with the switching assembly 73, the switching assembly 73 may be controlled to switch between different electrical circuits 32 according to the parameters of each electrical circuit 32 obtained by the controller 72, so as to ensure that the driving member 21 can operate normally.

For example, a switching component 73 may be disposed between the electrical circuits 32 of each photovoltaic power unit 31, and the controller 72 is further configured to obtain an electrical parameter of each electrical circuit 32, where in a case where the electrical parameter of one electrical circuit 32 is abnormal, the controller 72 is further configured to control the switching component 73 to switch to the other electrical circuit 32.

Note that, the switching element 73 may be a multi-state control switch, or a relay and a contactor may be used to manufacture the switching element 73, which is not limited in the embodiment of the present utility model.

The controller 72 may be used to obtain electrical parameters such as a voltage value, a current value, or an equivalent resistance value of the electrical circuit 32, and may determine whether the electrical circuit 32 is abnormal based on one electrical parameter such as the voltage value, or may determine whether the electrical circuit 32 is abnormal based on two or more electrical parameters such as the voltage value and the current value.

For both photovoltaic power components 31, a tri-state control switch 731 may be selected as the switching element 73 in embodiments of the present utility model. For convenience of description, the two photovoltaic power supply members 31 may be referred to as a first photovoltaic power supply member 31A and a second photovoltaic power supply member 31B, respectively, the electrical circuit 32 corresponding to the first photovoltaic power supply member 31A is referred to as a first electrical circuit 32A, the electrical circuit 32 corresponding to the second photovoltaic power supply member 31B is referred to as a second electrical circuit 32B, the driving element 21 corresponding to the first electrical circuit 32A is referred to as a first driving element 21A, and the driving element 21 corresponding to the second electrical circuit is referred to as a second driving element 21B.

By way of example, referring to fig. 3, the circuit connection may be made in the manner shown in fig. 3. Thus, the tri-state control switch 731 has a functional state of floating, closing the first electrical loop 32A or closing the second electrical loop 32B. When the temperature of the image capturing element 1 is less than or equal to the second preset threshold, the controller 72 controls the three-state control switch 731 to be in a suspended state, and at this time, the first electrical circuit 32A and the second electrical circuit 32B are both in an off state, so that the driving element 21 is in a stopped state. When the temperature of the image pickup element 1 is greater than or equal to the first preset threshold value, the tri-state control switch 731 controls the first electrical circuit 32A or the second electrical circuit 32B to be in a closed state, so that the driving element 21 is in an operating state, thereby cooling the image pickup element 1 and reducing the temperature of the image pickup element 1. In this regard,

in the case where the driver 21 is first connected to the first electrical circuit 32A and the electrical parameter of the first electrical circuit 32A is abnormal, the controller 72 can control the tri-state control switch 731 to switch so that the second electrical circuit 32B is in a closed state; in the case where the driver 21 is first connected to the second electrical circuit 32B and the electrical parameter of the second electrical circuit 32B is abnormal, the controller 72 can control the tri-state control switch 731 to switch so that the first electrical circuit 32A is in a closed state. It should be noted that the electrical circuit 32 that is preferably closed may be provided in advance, for example, in the electrical connection diagram shown in fig. 3, the first electrical circuit 32A may be provided to be preferably closed.

In this way, in the vehicle-mounted image pickup system provided by the embodiment of the utility model, through the redundancy arrangement, the cooling of the driving piece 21 to the image pickup piece 1 can be ensured, and the working performance of the image pickup piece 1 can be ensured. In particular, in the case of automatic driving of the vehicle 4, the requirement for the normal operation of the imaging device 1 is high, and the above arrangement can ensure the normal operation of the automatic driving of the vehicle 4.
