Detailed Description
The present invention is described in terms of particular embodiments, other advantages and features of the invention will become apparent to those skilled in the art from the following disclosure, and it is to be understood that the described embodiments are merely exemplary of the invention and that it is not intended to limit the invention to the particular embodiments disclosed. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 6, the invention provides a laser radar protection device for a vehicle, which aims to provide protection for a laser radar and drive the laser radar to intermittently lift by using a power device carried by the laser radar so as to play a role of cleaning at regular time. Specifically, the method comprises the following steps:
the radar protection device comprises a mounting bracket 1, a protection component 3 and a cleaning device 4.
The mounting bracket 1 movably mounts the laser radar 2, so that the laser radar can move in the vertical direction and has a buffering effect on external impact;
the protection component 3 can provide omnibearing protection for two forms of the laser radar 2, namely the laser radar 2 which is impacted and not impacted, and the service life of the laser radar 2 is prolonged;
The mounting bracket 1 comprises a lifting buffer component 101 and a guide component, and the laser radar 2 is mounted above the lifting buffer component 101 and can perform synchronous lifting motion along with the lifting buffer component 101. Particularly, when the buffer cushion is acted by external force, the buffer cushion can play an effective role. Specifically, the method comprises the following steps:
the lifting buffer assembly 101 comprises a lifting plate 103 and a linkage assembly, and the laser radar 2 is installed above the lifting plate 103.
The linkage assemblies are two groups which are arranged oppositely, so that the lifting stability of the lifting buffer assembly 101 can be improved. Each group of linkage assemblies comprises a first mounting plate 104 mounted on a roof sheet metal part and a second mounting plate 105 mounted on the lower surface of the lifting plate 103, a first movable plate 106 is hinged in the middle of the first mounting plate 104, and a second movable plate 107 is hinged in the middle of the second mounting plate 105. The middle part is hinged, so that the vertical supporting force transmitted by the first movable plate 106 and the second movable plate 107 can be transmitted to the first mounting plate 104 and the second mounting plate 105, the force bearing area of the linkage assembly and the connection part thereof is increased, and the force transmission is more uniform.
The first movable plate 106 and the second movable plate 107 are arranged with equal length, and two sets of the first movable plate 106 and the second movable plate 107 form opposite V-shaped openings. Here, the first movable plate 106 and the second movable plate 107 are connected in a non-contact manner. The equal length arrangement is intended to allow the first and second movable plates 106, 107 to deviate from an isosceles triangle configuration.
A hollow limiting sleeve 108 is arranged at the symmetrical axis position of the V-shaped opening, one end of each of the first movable plate 106 and the second movable plate 107 is hinged with the far end of the hollow limiting sleeve 108, and the two groups of hollow limiting sleeves 108 are connected through a return spring 109. At this time, the hollow position-limiting sleeve 108 can move horizontally in the linkage assembly due to the structure of the waist triangle. The return spring 109 is in a pulled-up state in a natural state.
Preferably, the sum of the lengths of the two sets of hollow limiting sleeves 108 is greater than the minimum distance between the two sets of linkage assemblies. After the force applied to the lifting buffer assembly 101 is removed, under the lifting action of the return spring 109, the two hollow limiting sleeves 108 approach each other, and finally the surfaces to be aligned contact each other, so that the support for the linkage assemblies on the two sides is formed, and at the moment, the laser radar 2 just extends out of the protection assembly 3.
It should be explained that: when the transparent protective cover 302 is pressed, the lifting plate 103 forces the linkage member downward, and after the external force is removed, the lifting plate 103 can be quickly restored to the original state under the elastic force of the linkage member.
The guide assembly is arranged to ensure vertical stable movement of the lidar 2 in the vertical direction.
The protective assembly 3 includes a protective frame 301 and a light-transmitting protective cover 302. A double layer of protection for the lidar 2 is formed. Specifically, the method comprises the following steps:
The light-transmissive protective cover 302 is preferably made of transparent tempered glass. The surface of the toughened glass is smooth, so that the transmission of laser signals of the laser radar 2 is not influenced; and on the other hand, the surface is toughened, so that drainage and surface cleaning are facilitated.
The guide assembly provides vertical guidance for the light transmissive protective cover 302. Specifically, the method comprises the following steps:
the guide assembly comprises a guide rail 110 arranged on a support column at the side of the protective frame 301, and a guide limiting block 111 matched with the guide rail 110 is arranged at the side of the lifting plate 103. When the laser radar 2 ascends and descends, the laser radar 2 also moves in the up-and-down direction because the lifting plate 103 below the laser radar can only move up and down under the guiding action of the guide rail 110.
Wherein, the cleaning device 4 is detachably arranged on the mounting bracket 1 and is matched with the periphery of the light-transmitting protective cover 302 in shape. The light-transmissive protective cover 302 in embodiments of the present invention is provided in a circular configuration. Therefore, the cleaning device 4 is disposed in a ring structure surrounding the light-transmissive shield 302, and when the light-transmissive shield 302 moves up and down, the cleaning device rubs against the brush of the cleaning device 4 to clean the dust on the surface of the light-transmissive shield 302.
Preferably, the cleaning device 4 comprises a sleeving ring 401, and a plurality of rubber brushes 402 facing the light-transmitting shield 302 are arranged on the inner side of the sleeving ring 401. Friction is formed between the rubber brush 402 and the surface of the light-transmitting shield 302, so that static electricity is easily generated to temporarily adsorb dust on the surface of the light-transmitting shield 302, and after the friction is removed, the dust on the rubber brush 402 with the static electricity gradually reduced is scattered due to wind power generated by vehicle running, so that the surface of the light-transmitting shield 302 is kept clean.
Since the conventional vehicle radar generally has a steering function, it has a driving unit 201 for driving the laser radar 2 to steer. The present invention considers the driving force as a driving force for driving the laser radar 2 to move up and down, thereby cleaning the surface of the laser radar 2. Specifically, the method comprises the following steps:
the driving part 201 of the laser radar 2 drives the lifting buffer component 101 to make intermittent lifting movement through the force transmission component 5, so that the light-transmitting protective cover 302 is in contact with the surface of the cleaning device 4.
The force transmission assembly 5 comprises a first driving assembly, a second driving assembly and a bidirectional worm 502, the driving part 201 drives the bidirectional worm 502 to rotate through the first driving assembly, and the bidirectional worm 502 drives the lifting plate 103 to lift through the second driving assembly;
the first driving assembly comprises a vertical sliding rail 501 arranged below the lifting plate 103, a rack plate 505 arranged in the vertical sliding rail 501 in a sliding manner, and a first pulley mounting plate 503 fixedly arranged on one side of the vertical sliding rail 501, wherein a first bevel gear 504 is mounted on the first pulley mounting plate 503 through a rotating shaft, a bevel incomplete gear 506 is mounted on a driving shaft of the driving part 201, the bevel incomplete gear 506 is meshed with the first bevel gear 504, the first bevel gear 504 is meshed with the rack plate 505, and a transmission latch 507 meshed with a latch of the rack plate 505 is arranged in the middle of the bidirectional worm 502;
the second driving assembly comprises worm wheels 508 which are arranged at two ends of the bidirectional worm 502 and are matched with worm insections 510 at two ends of the bidirectional worm 502, a latch lifting plate 509 is meshed and installed at one side of each worm wheel 508, and the latch lifting plate 509 is fixedly installed on the lifting plate 103.
Preferably, two sides of the bidirectional worm 502 are provided with worm mounting seats 511 for suspending the bidirectional worm 502, and the bidirectional worm 502 is spanned on the worm mounting seats 511 through bearings 512. The bearing 512 is utilized to improve the smooth degree of the rotation of the bidirectional worm 502 and ensure the favorable realization of the function of the device.
The working mode and principle of the invention are divided into two situations:
the first situation is as follows: when the laser radar works normally;
the laser radar 2 can complete the interval cleaning of surface dust through normal lifting. That is, the rotating shaft of the driving part 201 of the laser radar 2 drives the incomplete bevel gear 506 to move circularly, and the side of the incomplete bevel gear 506 having the teeth intermittently meshes with the first bevel gear 504 to drive, so that the rack plate 505 meshed with the first bevel gear 504 moves in one direction in the vertical direction. The rack plate 505 drives the bidirectional worm 502 to do radial rotary motion through the transmission latch 507, and then drives the latch lifting plate 509 to do descending motion through the worm wheel 508, namely, the lifting plate 103 where the latch lifting plate 509 is located also does descending motion, the transparent protective cover 302 on the lifting plate 103 is contacted with the cleaning device 4 in the descending process to finish one-time cleaning, and at the moment, the reset spring 109 in the lifting buffer component 101 is in a stretching state;
then, the side of the incomplete bevel gear 506 without the tooth pattern faces the first bevel gear 504, and since the first bevel gear 504 is not stressed, the lidar 2 on the lifting plate 103 is restored to the original state again, that is, above the protection frame 301, under the action of the tension of the return spring 109 of the lifting buffer assembly 101.
Case two: when the laser radar is impacted:
the light-transmitting protective cover 302 is pressed by the top and is retracted into the protective frame 301 together with the lower lifting plate 103, at this time, the first pulley mounting plate 503 below the lifting plate 103 moves downwards synchronously with the rack plate 510, and since the driving part 201 drives the same rack plate 510 on the first pulley mounting plate 503 to move downwards, the same rack plate 510 can obtain two downward speeds at the same time, so that the descending of the laser radar 2 on the lifting plate 103 can be accelerated, even though the laser radar 2 is effectively protected.
The protective frame and the light-transmitting protective cover form double-layer protection for the automotive laser radar, when the surface of the laser radar is pressed, the light-transmitting protective cover and the laser radar are immersed into the protective frame together, so that damage is avoided, and the radar can be accelerated to enter the protective frame for protection due to the action force for driving the laser radar to descend when the radar is clean; the laser radar is driven to synchronously move up and down by the rotating acting force of the rotating radar, and the laser radar rubs with the cleaning device arranged on one side of the laser radar, so that the surface of the radar is intermittently cleaned, dust on the surface of the radar is reduced, and the measurement accuracy of the radar is improved.
Although the invention has been described in detail above with reference to a general description and specific examples, it will be apparent to one skilled in the art that modifications or improvements may be made thereto based on the invention.
