[0001] The present invention relates to the technical field of image recognition, and in particular to an on-board image recognition device for a driving training vehicle. Background Art

[0002] The on-board image recognition device is one of the key technologies in autonomous driving and intelligent transportation systems. It is mainly used to detect and identify the vehicle's surrounding environment to improve driving safety. Among them, the on-board image recognition device of the driving training vehicle is mainly used to realize the intelligent management of driving training, improve training efficiency, and ensure the authenticity and safety of training. During the driving training process, the image recognition device is often under high load and needs to run for a long time. Therefore, the image recognition device needs to have good heat dissipation performance.

[0003] For example, Chinese patent No. CN118042255A discloses a vehicle-mounted image recognition device, including a shell, a camera module, a main board, heat dissipation holes and a heat sink; a accommodating cavity is provided in the shell, and a fixing hole for connecting the accommodating cavity with the outside is provided on the side wall of the shell, the camera module is arranged in the accommodating cavity and fixed to the inner wall of the fixing hole, the camera module is used to collect video image data of the driving process, the main board is arranged on the side of the camera module close to the bottom of the accommodating cavity, the main board is communicatively connected with the camera module, a plurality of heat dissipation holes are arranged on the peripheral side of the shell to exchange and connect the hot air in the accommodating cavity with the outside air, the heat sink is arranged on the outer wall of the shell close to the main board, and the heat sink is used to close to the main board for heat conduction; this application solves the heat dissipation problem when the vehicle-mounted camera is working.

[0004] However, when the vehicle-mounted camera is in a low temperature and relatively humid season (such as winter) or region, the high temperature generated by the image processor after the camera is used for a long time and then turned off will cause water vapor in the outside air to condense on the camera lens.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] See also Figures 1 to 10 The present invention provides a technical solution: an image recognition device mounted on a driving training vehicle, comprising a housing 1 that can be mounted on the outside of the vehicle, a housing cover 2 fixedly mounted on the side end of the housing 1, an inner compartment 4 provided in the housing 1, an image processor 13 provided in the inner compartment 4, and a lens 12 provided on the side end of the image processor 13;

[0035] It also includes a driving component, which is used to drive the image processor 13 to extend or retract into the inner compartment 4;

[0036] It also includes a wiping part, which has two states. In state one, the wiping part can clean the surface of the lens 12 when the image processor 13 is fully retracted into the inner chamber 4. In state two, the wiping part can exchange heat on the outer wall of the image processor 13 when the image processor 13 is fully extended out of the inner chamber 4.

[0037] The existing vehicle-mounted image recognition device can only uniformly dissipate heat for the internal components of the camera. In actual use, when the camera is in operation, the heat emitted will cause a heat flow layer to form on the camera surface, so that the moisture in the cold air cannot adhere to the outer wall or lens of the camera. However, when the camera stops working and begins to gradually cool down, the moisture in the air will gradually condense on the outer wall or lens of the camera, and damage the lens or other internal components through contraction and expansion during freezing or liquefaction. Moreover, the condensed frost will also hinder the image acquisition work of the camera. Therefore, the present invention aims to quickly cool down the camera after the camera stops working, and remove the condensed water condensed on the outer wall or lens surface of the camera during the cooling process. The specific implementation method is as follows:

[0038] When the device is in use, when the driving component drives the image processor 13 to extend out of the inner compartment 4, that is, when the camera is working normally, the wiping part is in state 2 and performs heat exchange and heat dissipation on the outer wall of the image processor 13. When the camera stops working, the image processor 13 is cooled together with the wiping part through the external natural low temperature environment. When the image processor 13 is consistent with the external environment temperature, the driving component drives the image processor 13 to retract into the inner compartment 4. Since the shell cover 2 and the outer shell 1 are both made of heat-insulating materials, the condensed water can only condense on the outer surface of the lens 12 after the elastic seal of the outer ring of the lens 12 is sealed and attached to the inner wall of the shell cover 2. For details, see Figure 1 At this time, the wiping part switches to state 1, and cleans the condensed water condensed on the outer surface of the lens 12 during cooling and heat dissipation, thereby completing the rapid cooling of the image processor 13 and the cleaning of the condensed water on the outer surface of the lens 12.

[0039] In this way, the lens 12 is driven to extend through the driving component to form a closed and heat-insulating space in the housing 1, and the condensation range of the condensed water formed when the camera stops working to dissipate heat is limited to the outer surface of the lens 12. In conjunction with the switching of the wiping part between the two states, the outer surface of the lens 12 is cleaned when the lens 12 is retracted to prevent the condensed water from directly condensing on the outer wall of the image processor 13 and causing damage to the image processor 13 and its internal components. The condensed water on the outer surface of the lens 12 is cleaned to prevent the condensed water on the surface of the lens 12 from further freezing, causing damage and obstruction to the surface of the lens 12, and affecting the normal operation of the camera.

[0040] Furthermore, the wiping portion includes an annular groove 5 and an annular groove 6 opened in the outer shell 1. An elastic ring that can be flipped into the annular groove 6 is provided in the annular groove 5. The elastic ring consists of an outer ring 14 and an inner ring 18. Both the outer ring 14 and the inner ring 18 are water-absorbent, and the water absorption of the outer ring 14 is greater than that of the inner ring 18. A resistance ring 21 is fixedly installed on the inner wall of the outer shell 1 between the annular groove 5 and the annular groove 6.

[0041] According to the above embodiment, a specific embodiment of the wiping portion is provided. When the driving component drives the lens 12 to extend, the elastic seal of the outer ring of the lens 12 pushes the elastic ring to start flipping under the action of the resistance ring 21, so that the inner ring 18 is flipped out to the position of the outer ring 14, and the outer ring 14 is flipped into the position of the inner ring 18, that is, the inner ring 18 and the outer ring 14 are swapped with each other. At this time, the elastic ring is flipped into the annular groove 6 as a whole and wrapped around the outer wall of the fixed sleeve 9, so as to perform heat exchange and heat dissipation for the image processing in the fixed sleeve 9. When the driving component drives the lens 12 to retract, the elastic seal of the outer ring of the lens 12 drags the elastic ring to the resistance ring 21. Under the action, it begins to flip and flip back into the ring groove 5 until the lens 12 is separated from the elastic ring. When the lens 12 and the image processor 13 are completely retracted into the inner chamber 4, the driving component pushes the lens 12 to pop out in the opposite direction until it contacts and abuts against the inner ring 18. The inner ring 18 absorbs the condensed water on the outer surface of the lens 12 through its own water absorption, and transfers the water to the outer ring 14 with higher water absorption. The outer ring 14 uses its own water absorption to store the condensed water until the next time the elastic ring flips, and uses the internal water to exchange heat with the outer wall of the fixed sleeve 9 to dissipate heat, so as to avoid the image processor 13 becoming insensitive or stuck due to excessive internal temperature.

[0042] In this way, by flipping the inner ring 18 and the outer ring 14 back and forth, the inner ring 18 can be detached from the lens 12 after collecting the condensed water, and cooperate with the outer ring 14 to use the condensed water for heat exchange with the image processor 13, thereby avoiding the image processor 13 from overheating while cleaning the condensed water on the outer surface of the lens 12 to prevent the condensed water from freezing and damaging the lens 12.

[0043] Furthermore, the driving assembly includes a piston plate 7 slidably installed in the inner warehouse 4, the side wall of the piston plate 7 is provided with an electromagnet, the inner wall of the outer shell 1 is provided with a magnetic block that can attract or repel the electromagnet, and a fixed sleeve 9 is fixedly installed on the other side of the piston plate 7. The image processor 13 is slidably installed in the fixed sleeve 9, and a spring 10 is provided between the inner wall of the fixed sleeve 9 and the side wall of the image processor 13. High and low grooves are opened on the inner wall of the fixed sleeve 9, and the high and low grooves are composed of two groups of low inclined grooves 16 and two groups of high inclined grooves 17 that are alternately connected end to end in sequence, and the connecting line between the two inflection points at the connection between the low inclined groove 16 and the high inclined groove 17 is not parallel to the axis of the fixed sleeve 9, and a limit block 11 that can slide in the high and low grooves is fixedly installed on the outer wall of the fixed sleeve 9.

[0044] According to the above embodiment, a specific embodiment of a driving assembly is provided. Figure 4When the electromagnet repels the magnetic block, the piston plate 7 moves toward the shell cover 2, driving the image processor 13 to move together. When the elastic seal of the outer ring of the lens 12 contacts and abuts against the inner ring 18, the lens 12 and the image processor 13 slide together along the fixed sleeve 9 and compress the spring 10. At this time, the limit block 11 slides from the high inclined groove 17 to the low inclined groove 16, and the lens 12 and the image processor 13 rotate 90 degrees together. The friction between the lens 12 and the inner ring 18 is used to wipe the outer surface of the lens 12. When the piston plate 7 Continue to move until the lens 12 fits into the groove on the inner wall of the shell cover 2, and the fixed sleeve 9 continues to compress the spring 10, so that the limit block 11 slides into the high inclined groove 17. At this time, the inner ring 18 and the outer ring 14 complete the flipping, and the camera starts to work. When the camera stops working, the electromagnet and the magnetic block are attracted to each other, so that the piston plate 7 is reset. When the piston plate 7 pulls the lens 12 to completely retract the inner chamber 4, the spring 10 loses resistance and begins to reset, pushes out in the opposite direction, and makes the lens 12 contact and resist the inner ring 18, and uses the water absorption of the inner ring 18 to clean the outer surface of the lens 12.

[0045] In this way, through the attraction or repulsion between the electromagnet and the magnetic block, the limit block 11 slides in the high inclined groove 17 and the low inclined groove 16, so that the lens 12 can be pushed out in the reverse direction after being fully retracted into the inner bin 4 and contact and resist against the inner ring 18, and the water absorption of the inner ring 18 is utilized to absorb the condensed water condensed on the outer surface of the lens 12, thereby completing the cleaning of the outer surface of the lens 12.

[0046] It is worth mentioning that since the line between the two inflection points at the connection between the low inclined groove 16 and the high inclined groove 17 is not parallel to the axis of the fixed sleeve 9, see Fig.10 The vertical line segments where the upper inflection point and the lower inflection point are located are at a certain distance, so that the limit block 11 can only slide to the left in the figure, preventing the limit block 11 from sliding backward so that the lens 12 cannot contact and resist the inner ring 18 after being fully retracted, making the inner ring 18 ineffective in cleaning the outer surface of the lens 12.

[0047] Furthermore, a plurality of exhaust holes 3 are distributed in a ring shape on the outer wall of the shell cover 2, an air pipe groove 20 is provided on the inner wall of the outer shell 1 to connect the inner chamber 4 with the exhaust holes 3, a one-way air outlet valve is provided in the exhaust hole 3, an air hole 8 is provided on the side wall of the piston plate 7, a one-way air outlet valve is also provided in the air hole 8, and a one-way air inlet is also provided on the side wall of the inner chamber 4.

[0048] According to the above embodiment, when the driving assembly drives the retracted lens 12 to push out in the reverse direction and abut against the inner ring 18, the Figure 8At this time, the air on the right side of the inner chamber 4 enters the left side of the piston plate 7 through the air hole 8, so that the air pressure inside the inner chamber 4 on the left side of the piston plate 7 increases, and the gas is slowly squeezed out of the exhaust hole 3 through the air pipe groove 20, so that the remaining heat inside the image processor 13 can be taken out, and the temperature of the image processor 13 can be kept consistent with the external environment as much as possible, to avoid excessive residual heat remaining inside the image processor 13 after the image processor 13 is retracted into the inner chamber 4, so that the condensed water on the surface of the lens 12 condenses too much and exceeds the absorption limit of the elastic ring, causing the device to fail, and the heat generated by the outer ring 14 when exchanging heat with the image processor 13 and the water vapor evaporated in the outer ring 14 are discharged from the outer shell 1 together, so as to complete the heat dissipation of the image processor 13.

[0049] When the driving assembly drives the lens 12 to extend out of the inner chamber 4, since a one-way air outlet valve is also provided in the air hole 8, the gas on the left side of the inner chamber 4 is squeezed by the piston plate 7 and slowly squeezed out of the exhaust hole 3 through the air pipe groove 20, thereby discharging excess water vapor in the outer shell 1.

[0050] Furthermore, a plurality of groups of oblique grooves 15 are provided on the side wall of the outer ring 14 .

[0051] According to the above embodiment, a specific embodiment is provided to enable the elastic ring to rotate. When the gas is slowly squeezed out of the exhaust hole 3 through the tracheal groove 20, it will pass through the multiple groups of oblique grooves 15 provided on the side wall of the outer ring 14, so that the outer ring 14 drives the elastic ring to rotate as a whole. Figure 8 At this time, because the driving component drives the retracted lens 12 to push out in the opposite direction and abut against the inner ring 18, the inner ring 18 can rotate along the outer surface of the lens 12 and absorb the condensed water attached to the outer surface of the lens 12, so as to achieve the purpose of improving the cleaning effect of the condensed water on the outer surface of the lens 12. When the driving component drives the lens 12 to extend out of the inner chamber 4, the rotating ring rotates to wipe the outer surface of the lens 12, and cleans the dirt that may exist on the outer surface of the lens 12, so as to avoid the image acquisition device from being unable to operate.

[0052] Furthermore, an annular cavity 23 is formed on the inner wall of the annular groove 5 and the annular groove 6 which is tangent to the elastic ring, and balls 22 which can make point contact with the elastic ring are disposed in the two annular cavities 23 .

[0053] According to the above embodiment, a specific embodiment is provided to facilitate the rotation of the elastic ring. When the gas passes through the multiple groups of oblique grooves 15 provided on the side wall of the outer ring 14, the elastic ring as a whole will be driven to rotate. Since annular cavities 23 are provided on the inner walls of the annular grooves 5 and 6 that are tangent to the elastic ring, and balls 22 that can make point contact with the elastic ring are provided in the two annular cavities 23, the friction between the elastic ring and the inner walls of the annular grooves 5 and 6 is reduced, thereby preventing the air flow velocity from being too low to drive the elastic ring to rotate, thereby reducing the cleaning effect of the inner ring 18 on the outer surface of the lens 12 and causing residual condensed water.

[0054] Embodiment 1:

[0055] Furthermore, a slot 19 for inserting the outer ring elastic member of the lens 12 is provided on the side wall of the elastic ring close to the lens 12, and a plurality of groups of protrusions are arranged in a circular pattern on the outer wall of the fixing sleeve 9.

[0056] According to the above embodiment, a specific embodiment is provided to facilitate the flipping of the elastic ring. When the driving assembly drives the lens 12 to extend out of the inner chamber 4, the elastic seal on the outer ring of the lens 12 will first be inserted into the slot 19, so that the side wall of the inner ring 18 is subjected to annular pressure, and cooperates with the resistance ring 21 to cause the elastic ring to start flipping. When the elastic member flips over until the elastic seal is out of the slot 19, the protrusion on the outer wall of the fixed sleeve 9 will increase the friction between the elastic ring and the fixed sleeve 9, and continue to drive the elastic ring to complete the flipping.

[0057] In this way, through the cooperation between the protrusion on the outer wall of the fixed sleeve 9 and the slot 19, the force on the elastic ring during flipping is distributed in an annular shape, which improves the uniformity of the force and makes it easier for the elastic ring to complete flipping.

[0058] Furthermore, a capillary core is provided in the inner ring 18, and the portion of the capillary core extending out of the outer wall of the inner ring 18 is provided as a water absorbent strip.

[0059] According to the above embodiment, when the driving assembly drives the retracted lens 12 to push out in the reverse direction and abut against the inner ring 18, the airflow drives the elastic ring to start rotating. Figure 8 At this time, the water absorption strips on the outer wall of the inner ring 18 will absorb the condensed water on the outer surface of the lens 12 and introduce it into the outer ring 14 through the capillary core. After the inner ring 18 and the outer ring 14 are swapped, the moisture in the outer ring 14 can be used to cool the outer wall of the image processor 13, and the hot air and the water vapor formed by evaporation can be discharged from the outer shell 1 through the slowly flowing airflow.

[0060] Embodiment 2:

[0061] Furthermore, the outer wall of the elastic ring is provided with a plurality of elastic hoops 24 in an annular shape.

[0062] According to the above embodiment, a second specific embodiment is provided to facilitate the flipping of the elastic ring. Since the outer wall of the elastic ring is annularly provided with a plurality of elastic hoops 24, see the specific embodiment of the present invention. Fig. 9 When the elastic seal of the outer ring of the lens 12 abuts against the elastic ring and drives the elastic ring to flip, the elastic hoop 24 can make the stress distribution of the elastic seal on the elastic ring more uniform, which not only facilitates the flipping of the elastic ring, but also enables the elastic ring to maintain stability during the flipping process, avoiding inconsistent flipping degrees of various parts of the elastic ring during flipping, resulting in excessive flipping of the elastic ring or failure to flip completely.

[0063] It is worth mentioning that there is no conflict between the implementation methods in Example 1 and Example 2, and they can be used alone or in combination with each other.

[0064] Furthermore, the inner walls of the annular groove 5 and the annular groove 6 can fit with the outer wall of the elastic ring, and the distance between the two annular cavities 23 is half of the circumference of the cross section of the elastic ring.

[0065] According to the above embodiment, since the distance between the two annular cavities 23 is half the circumference of the cross section of the elastic ring, when the elastic ring is pushed by the lens 12 and is flipped by the resistance ring 21, it can just move from the annular groove 5 to the annular groove 6, thereby preventing the elastic ring from rotating too much or too little when flipping, so that the inner ring 18 and the outer ring 14 cannot exchange positions normally, which affects the subsequent cleaning or heat dissipation.

[0066] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification and the drawings can also be directly processed according to the existing technical common sense without any doubt. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
