Description

Technical Field

[0001] The invention belongs to the technical field of vehicle-mounted cameras, and in particular relates to a front camera for assisting vehicle driving. Background Art

[0002] The front camera is used to record the audio data of the driving field of view in real time. It is generally installed between the front windshield and the rearview mirror inside the car. At the same time, in order to avoid blocking the driver's line of sight, the lens surface of the camera is often close to the front windshield; but when the car is driving through an environment with a large temperature difference with the interior of the car, such as entering a valley or going to a cooling area, the sudden change in temperature between inside and outside the car will directly cause water droplets to condense on the mirror surface inside the car and the mirror surface of the camera, which will directly blur the image captured by the camera. In addition, there is currently a lack of equipment for wiping the lens in time, so the driver has to wipe it manually while the car is driving, which is inconvenient to wipe the camera lens surface dry, and will affect driving safety. In view of this, overcoming the defects of the above-mentioned prior art is a problem that needs to be urgently solved in this technical field. Summary of the invention

The side wall of the guide rod forms a sliding abutment with one end of the water absorption rod, and the distance between the side wall of the guide rod and the center point of the ring block gradually decreases along the rotation direction of the ring block. When the driving assembly drives the ring block to rotate, the guide rod squeezes the water absorption rod to move toward the direction of the lens of the image acquisition device and makes the side wall of the water absorption rod fit with the end wall of the lens of the image acquisition device.

[0005] Furthermore, a groove is provided on one side wall of the housing, and the ring block, the driving assembly and the guide rod are all arranged in the groove;

[0007] Furthermore, the driving assembly includes a rotating motor embedded in the slot body, a driving gear is coaxially mounted on the output end of the rotating motor, and teeth meshing with the driving gear are formed on the outer wall of the ring block.

[0008] Furthermore, it also includes a control panel, which is electrically connected to the push rod motor and the rotating motor, and the control panel is electrically connected to the vehicle control system.

[0009] Furthermore, the water-absorbing rod includes an end block and mutually connected water-absorbing cotton columns and strips;

[0010] The absorbent cotton column and the strip plate are arranged in parallel and form a sliding sleeve connection with the guide through hole. The ends of the absorbent cotton column and the strip plate close to the guide rod are connected to the end block together. The side wall of the end block close to the fixed block is connected to the fixed block through a spring.

[0011] Furthermore, a through hole for accommodating the absorbent cotton column and the end of the strip is provided on the side wall of the end block, and a threaded hole arranged vertically and connected to the through hole is also provided on the end block, and a limit screw is threadedly connected in the threaded hole.

[0012] Furthermore, the guide rod adopts an arc structure, and the center angle of the guide rod is greater than 180°, and the distance between the starting point where the guide rod side wall and the fixed block form extrusion and the inner wall of the ring block is greater than or equal to the length of the water absorption rod.

[0013] Furthermore, a through hole for accommodating a lens of the image acquisition device is provided on the side wall of the shell, and the length of the water absorption rod is greater than the inner diameter of the through hole.

[0014] Furthermore, the shell includes a base and a pressing plate that are interlocked, an outer tube facing the pressing plate is arranged on the side wall of the base, a through hole matching the outer tube is opened on the pressing plate, and the end of the outer tube facing the pressing plate is threadedly connected to the limit screw;

[0019] 2. Based on the guide rod adopting an arc structure and being provided with a spring, when the water absorption rod is separated from the extrusion of the guide rod, the water absorption rod performs a reset movement under the reaction force of the spring. In this process, since the guide through hole limits the outer diameter of the water absorption rod, an extrusion force is generated on the water absorption rod after absorbing water vapor and the outer wall of the water-absorbing cotton column is combed to squeeze out excess water in the water absorption rod, which is convenient for subsequent reuse. After the spring completes the reset movement, the side wall of the water absorption rod is misaligned with the lens of the image acquisition device, avoiding the normal operation of the image acquisition device.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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.

[0032] The present invention provides a front camera for assisting automobile driving. Figure 1 A schematic diagram of a front camera for assisting car driving in an embodiment of the present invention is shown. Figure 1 ,refer to Figure 1-Figure 4 In the figure, the front camera for assisting automobile driving comprises a housing 1, an image acquisition device 2 installed in the inner cavity of the housing 1, a ring block 4 coaxially arranged with the lens of the image acquisition device 2 is rotatably installed on one side wall of the housing 1, a fixing block 5 is fixedly installed on the side wall of the ring block 4, a guide through hole 7 facing the center of the ring block 4 is opened on the fixing block 5, a water absorption rod 8 is slidably sleeved on the guide through hole 7, and the water absorption rod 8 is coplanar with the end wall of the lens of the acquisition device 2 close to the side wall of the housing 1;

[0033] A guide rod 9 and a driving assembly are also installed on the side wall of the shell 1. The driving assembly is connected to the ring block 4 in a transmission manner. The side wall of the guide rod 9 forms a sliding abutment with one end of the water absorption rod 8, and the distance between the side wall of the guide rod 9 and the center point of the ring block 4 gradually decreases along the rotation direction of the ring block 4, so that when the driving assembly drives the ring block 4 to rotate, the guide rod 9 squeezes the water absorption rod 8 to move toward the direction of the lens of the image acquisition device 2 and makes the side wall of the water absorption rod 8 fit with the end wall of the lens of the image acquisition device 2.

[0034] During the actual use of the structure of the present application, when the driving assembly drives the ring block 4 to rotate, the side wall of the guide rod 9 will form a sliding abutment with one end of the water absorption rod 8, and the relative position of the water absorption rod 8 relative to the lens of the image acquisition device 2 will change as the distance between the side wall of the guide rod 9 and the center point of the ring block 4 changes, so that during the use of the device, the water absorption rod 8 will periodically wipe the lens of the image acquisition device 2, thereby achieving comprehensive cleaning of the lens of the image acquisition device 2.

[0035] Here, there is no restriction on the specific shape of the guide rod 9. The guide rod 9 may adopt an elliptical structure, or the guide rod 9 may be arranged below the water absorption rod 8, so that the water absorption rod 8 naturally slides along the guide through hole 7 under the action of its own gravity until the end of the water absorption rod 8 contacts the side wall of the guide rod 9.

[0036] A groove 10 is provided on one side wall of the housing 1, and the ring block 4, the driving assembly, and the guide rod 9 are all arranged in the inner cavity of the groove 10. Figure 2 In the example shown, the groove body 10 includes a square groove for accommodating the through hole 3, the ring block 4, and the driving assembly, and a strip groove for accommodating the guide rod 9, so that the side walls of the through hole 3, the ring block 4, and the driving assembly are all coplanar with the side wall of the shell 1 on this side. At the same time, the lens of the image acquisition device 2 is also coplanar with the side wall of the shell 1 on this side. The fixing block 5 is fixedly arranged on the side wall of the ring block 4, and the working surface of the water absorption rod 8 is also coplanar with the side wall of the shell 1 on this side, ensuring that the working surface of the water absorption rod 8 is coplanar with the lens end arm of the image acquisition device 2.

[0037] At the same time, a push rod motor 13 is embedded in the groove body 10, and the output end of the push rod motor 13 is fixedly connected to the side wall of the guide rod 9. The push rod motor 13 can drive the guide rod 9 to move closer to or away from the groove body 10, that is, drive the guide rod 9 to protrude outward from the strip groove or to retract from the outside into the strip groove. When the device of the present application is not performing cleaning operations, the guide rod 9 is stored in the groove body 10, avoiding the external design of the guide rod 9 and improving the integrity of the device.

[0038] In order to ensure the stability of the transmission connection between the drive assembly and the ring block 4, the drive assembly includes a rotating motor 11 embedded in the slot body 10, and a driving gear 12 is coaxially installed at the output end of the rotating motor 11, and the outer wall of the ring block 4 is provided with teeth meshing with the driving gear 12. The rotating motor 11 drives the ring block 4 to rotate through the driving gear 12, and then drives the fixed block 5 to rotate in a circle, thereby achieving a precise braking effect through the gears.

[0039] In order to realize the convenience of the device of the present application during the automobile operation, the device of the present application also includes a control panel 14, which is electrically connected to the push rod motor 13 and the rotating motor 11, and the control panel 14 is electrically connected to the automobile control system. On the one hand, the control panel 14 is used to coordinate and control the operation of the push rod motor 13 and the rotating motor 11 to ensure the degree of coordination between the push rod motor 13 and the rotating motor 11, so as to realize the operation sequence of first pushing the guide rod 9 outward by the push rod motor 13 and then driving the ring block 4 by the rotating motor 11; secondly, a connection is established with the automobile control system to facilitate direct contact with the automobile and improve the convenience of the device in use.

[0040] By acquiring the electrical signal of the automobile control system, the push rod motor 13 and the rotating motor 11 are started or shut down. When started, the push rod motor 13 pushes the guide rod 9 outward so that the ends of the guide rod 9 and the water absorption rod 8 are located on the same working surface. The rotating motor 11 drives the ring block 4 to rotate, thereby driving the fixed block 5 to rotate in a circle. When the end of the water absorption rod 8 located at the outer circle position abuts against the side wall of the guide rod 9, as the distance between the side wall of the guide rod 9 and the center point of the ring block 4 gradually decreases along the rotation direction of the ring block 4, the side wall of the guide rod 9 squeezes the water absorption rod 8 to move toward the direction of the lens of the image acquisition device 2, and the working surface of the water absorption rod 8 gradually fits with the end wall of the lens of the image acquisition device 2, and the size of the fitting area increases or decreases with the movement distance of the water absorption rod 8 toward the lens of the image acquisition device 2.

[0041] Specifically, refer to Figure 5 and Figure 6 The water-absorbing rod 8 includes an end block 801 and an absorbent cotton column 802 and a strip board 803 that are interconnected. The absorbent cotton column 802 and the strip board 803 are arranged in parallel and form a sliding sleeve connection with the guide through hole 7. The absorbent cotton column 802 and the strip board 803 can be connected in a detachable manner such as glue and snaps to facilitate the assembly of the absorbent cotton column 802 and the strip board 803. On the basis of using the absorbent cotton column 802 to achieve the water absorption function, the strip board 803 is additionally provided to limit the extension form of the absorbent cotton column 802 to avoid bending of the absorbent cotton column 802 and affecting the smoothness of the sliding sleeve connection between the absorbent cotton column 802 and the guide through hole 7. Those skilled in the art can make comprehensive considerations based on the connection principle of the present invention and the actual application situation, as long as the principle of the present invention can be realized.

[0042] The ends of the absorbent cotton column 802 and the strip plate 803 near the guide rod 9 are connected to the end block 801 together. The side wall of the end block 801 near the guide rod 9 adopts a curved surface structure and is adapted to the side wall of the guide rod 9 to reduce the friction between the end block 801 and the side wall of the guide rod 9 during sliding friction. The side wall of the end block 801 near the fixed block 5 is connected to the fixed block 5 through a spring 806, and the relative position of the end block 801 and the fixed block 5 is limited by the spring 806. When the side wall of the guide rod 9 does not exert a force on the end block 801, the spring 806 is in a stable state, and the working surface of the water-absorbing rod 8 and the end wall of the lens of the image acquisition device 2 do not form an overlapping surface; when the side wall of the guide rod 9 squeezes the end block 801 to make the water-absorbing rod 8 move toward the direction of the lens of the image acquisition device 2, the spring 806 is in a compressed state and the distance between the end block 801 and the fixed block 5 gradually decreases, and the working surface of the water-absorbing rod 8 and the end wall of the lens of the image acquisition device 2 form an overlapping surface, and the area of ​​the overlapping surface gradually increases.

[0043] Specifically, a through hole 804 for accommodating the end of the absorbent cotton column 802 and the strip 803 is provided on the side wall of the end block 801. A threaded hole is also provided on the end block 801 and is arranged vertically with and connected to the through hole 804. A limit screw 805 is threadedly connected in the threaded hole. The limit screw 805, which is perpendicular to the extension direction of the absorbent cotton column 802, is used to squeeze the absorbent cotton column 802 from the side wall of the absorbent cotton column 802, and the end of the absorbent cotton column 802 is squeezed into the through hole 804 to fix the end of the absorbent cotton column 802. The fixation of the absorbent cotton column 802 can also be released by the limit screw 805, and the absorbent cotton column 802 and the strip 803 can be disassembled and replaced.

[0044] Specifically, refer to Figure 2 In the example shown, the drive assembly and the push rod motor 13 are respectively located on the left and right sides of the ring block 4, and the guide rod 9 is located above the ring block 4. The guide rod 9 adopts an arc structure, and the center angle of the guide rod 9 is greater than 180°. The guide rod 9 forms a semi-enclosed state for the ring block 4, and the distance between the guide rod 9 and the center of the ring block 4 gradually decreases from the left end of the guide rod 9 to the right end of the guide rod 9.

[0045] At the same time, the distance between the starting point of extrusion formed by the side wall of the guide rod 9 and the fixed block 5 and the inner wall of the ring block 4 is greater than or equal to the length of the water absorption rod 8, so as to avoid collision between the water absorption rod 8 and the end of the guide rod 9, resulting in the guide rod 9 being unable to rotate under the drive of the ring block 4.

[0046] When the driving assembly drives the ring block 4 to rotate, the ring block 4 rotates clockwise; during the rotation of the ring block 4, based on the arc-shaped structure of the guide rod 9, the water absorption rod 8 and the side wall of the guide rod 9 will change from a non-contact state to a contact state with the left end of the guide rod 9, and then to a contact state with the right end of the guide rod 9, and finally break away from the extrusion of the guide rod 9 and form a non-contact state with the guide rod 9.

[0047] During the process of the water absorption rod 8 and the guide rod 9 forming contact, the water absorption rod 8 moves toward the direction of the lens of the image acquisition device 2 under the squeezing of the guide rod 9, the spring 806 is gradually squeezed, the working surface of the water absorption rod 8 is in contact with the end wall of the lens of the image acquisition device 2 and absorbs the water vapor on the end wall of the lens of the image acquisition device 2. At the same time, a through hole 3 for accommodating the lens of the image acquisition device 2 is opened on the side wall of the shell 1, and the length of the water absorption rod 8 is set to be greater than the inner diameter of the through hole 3, so that in the process of at least 180° rotation, the water absorption rod 8 can achieve a comprehensive cleaning of the lens of the image acquisition device 2.

[0048] When the water absorption rod 8 is separated from the squeezing of the guide rod 9, the water absorption rod 8 performs a reset movement under the reaction force of the spring 806. During this process, since the guide through hole 7 will limit the outer diameter of the water absorption rod 8, an extrusion force is generated on the water absorption rod 8 after absorbing water vapor and the outer wall of the absorbent cotton column 802 is combed to squeeze out excess water in the water absorption rod 8 for subsequent reuse. After the spring 806 completes the reset movement, the side wall of the water absorption rod 8 is misaligned with the lens of the image acquisition device 2, and the water absorption rod 8 is removed from the field of view of the image acquisition device 2 to avoid affecting the normal operation of the image acquisition device 2.

[0049] refer to Figure 7 and Figure 8 The shell 1 includes a base 101 and a pressure plate 102 that are buckled together. An outer tube 103 facing the pressure plate 102 is arranged on the side wall of the base 101. A through hole adapted to the outer tube 103 is opened on the pressure plate 102, and the end of the outer tube 103 facing the pressure plate 102 is threadedly connected with a limiting screw 104. During the buckling process of the base 101 and the pressure plate 102, the outer tube 103 on the side wall of the base 101 is inserted into the through hole on the pressure plate 102, and then the limiting screw 104 is threadedly installed on the end of the outer tube 103, so that the nut portion of the limiting screw 104 and the end of the outer tube 103 clamp the pressure plate 102, thereby realizing the relative fixation of the base 101 and the pressure plate 102.

[0050] In addition, the shell 1 also includes a connecting block 105 installed on the outer wall of the base 101. The connecting block 105 rotates and hinges one end of the connecting rod 106, and the other end of the connecting rod 106 is fixedly connected to a suction cup 107 for connecting to the car, which facilitates the overall installation of the shell 1 and the adjustment of the placement angle of the shell 1.

[0051] In addition, a heat dissipation through hole is provided at the center of the side wall of the pressing plate 102 of the present application to facilitate heat dissipation and installation of the image acquisition device 2 .
