DETAILED DESCRIPTION

[0039] Preferred embodiments of the present application will be described in more detail below. Although the following describes preferred embodiments of the present application, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present application is more thoroughly and completely conveyed to those skilled in the art, and the scope of the present application is fully conveyed to those skilled in the art.

[0040] The present application provides a laser radar collision protection device, comprising:

[0041] A connecting assembly, one end of which is used for connecting with the front anti-collision beam assembly;

[0042] A position adjustment assembly, which is sleeved on the other end of the connecting assembly;

[0043] A pre-limiting assembly, which is arranged on the other end of the connecting assembly, and the pre-limiting assembly can fix the installation position of the position adjustment assembly;

[0044] A final limiting assembly, which is arranged on the other end of the connecting assembly, and the final limiting assembly can stop the movement of the position adjustment assembly when the position adjustment assembly is moved towards the front anti-collision beam due to collision.

[0045] Specifically, the collision protection device connects the laser radar to the front bumper beam assembly through the connecting assembly and the position adjusting assembly, one side of the position adjusting assembly is sleeved on the end of the connecting assembly, and the position adjusting assembly is fixed by using the pre-limiting assembly after being installed in place, so that the assembly precision of the laser radar is guaranteed, the position adjusting assembly cannot be displaced during vehicle driving, the normal use of the laser radar is avoided, the measurement precision of the laser radar is guaranteed, and the connecting assembly and the position adjusting assembly support the laser radar; when the laser radar is displaced during vehicle collision, the laser radar drives the position adjusting assembly to move in the direction of the vehicle interior by breaking through the limitation of the pre-limiting assembly, the position adjusting assembly buffers the impact force received by the laser radar by moving, and the position adjusting assembly stops moving when the position adjusting assembly is attached to the final limiting assembly.

[0046] In one embodiment, the collision protection device is designed in an aluminum alloy structure, is novel in structure, has obvious lightweight effect, has a large precision adjustment range, is reliable in support stiffness, is suitable for batch production, and can be widely promoted.

[0047] Optionally, the pre-limiting assembly is provided with at least two groups, the pre-limiting assemblies are uniformly arranged along the width direction of the position adjusting assembly, each group of pre-limiting assemblies includes two limiting blocks, the limiting blocks are detachably connected with the connecting assembly, and the two limiting blocks are arranged on the two sides of the position adjusting assembly.

[0048] Specifically, the position of the pre-limiting assembly corresponds to the end of the position adjusting assembly in the horizontal direction, after the position adjusting assembly is sleeved on the end of the connecting assembly and reaches the installation position, the two limiting blocks are inserted on the fixing holes of the connecting assembly to fix and limit the two sides of the sleeving direction of the position adjusting assembly, so that the position adjusting assembly and the laser radar mounted thereon cannot be displaced during automobile driving, so that the detection position of the laser radar is ensured to be correct; in addition, after the laser radar is impacted and moves together with the position adjusting assembly, the limiting blocks are damaged by the impact force, and when the position adjusting assembly is reinstalled again, the installation and positioning of the laser radar can be realized by using new limiting blocks to be installed on the fixing holes.

[0049] In one embodiment, the limiting block is made of rubber, so that the rubber limiting block can buffer and limit the laser radar when the laser radar bounces with the automobile.

[0050] Optionally, the final limiting assembly includes at least two limiting rods, the limiting rods are arranged on the position adjusting assembly, and the planes formed by all the limiting rods are perpendicular to the movement direction of the position adjusting assembly.

[0051] Specifically, a plurality of limiting rods are arranged on the connecting assembly. When the laser radar is impacted and moves together with the position adjusting assembly, the distance between the limiting rods and the limiting blocks is used to release the impact force received by the laser radar. When the impact force is released to a certain extent, the position adjusting assembly is limited by the plurality of limiting plates, so that the position adjusting assembly is prevented from continuing to move, the laser radar is prevented from contacting the vehicle body panel, and the probability of damage to the laser radar is reduced.

[0052] Optionally, the connecting assembly comprises:

[0053] The transverse connecting plate is in an L shape, and a short side end of the transverse connecting plate is used to be connected with the front anti-collision beam assembly;

[0054] A plurality of longitudinal guide ribs are arranged on both sides of a long side end of the transverse connecting plate, and the longitudinal guide ribs are integrally formed in a T shape with the transverse connecting plate.

[0055] Specifically, the connecting assembly comprises a transverse connecting plate and a plurality of longitudinal guide ribs. One end of the transverse connecting plate is bolted to the front anti-collision beam assembly, the other end of the transverse connecting plate is connected to the longitudinal guide ribs, and the longitudinal guide ribs form a T-shaped structure with the upper and lower sides of the transverse connecting plate, thereby supporting and limiting the position adjusting assembly.

[0056] In one embodiment, the transverse connecting plate adopts a crash crushing L-shaped design and is provided with a crushing boundary line, so that the laser radar can be bent backward along the crushing boundary line when the laser radar is impacted by the outside world, thereby reducing damage to the laser radar.

[0057] Optionally, the pre-limiting assembly is arranged on the longitudinal guide rib at each end, and the middle part of the limiting rod penetrates the longitudinal guide rib on the same side.

[0058] Specifically, since the position adjusting assembly is arranged on the end of the connecting assembly, a groove is arranged on the side of the position adjusting assembly close to the transverse connecting plate. The shape of the groove corresponds to the positions of the longitudinal guide ribs and the transverse connecting plate. The limiting block is arranged on the outermost longitudinal guide rib, and the end region of the position adjusting assembly connected with the connecting assembly is limited by the limiting block. When the automobile is running, the limiting block fixes the moving direction of the position adjusting assembly along the transverse connecting plate. When the laser radar is displaced due to the collision of the automobile, the position adjusting assembly can easily break the limitation of the limiting block and start to move, thereby reducing the impact force received by the position adjusting assembly. The limiting rod is arranged on the longitudinal guide rib, and both ends of the limiting rod are exposed outside the outermost longitudinal guide rib. When the position adjusting assembly moves in the direction of the transverse connecting plate towards the inside of the automobile, the moving direction of the position adjusting assembly is perpendicular to the plurality of limiting rods, thereby forming a force bearing surface. The force bearing surface is used to prevent the position adjusting assembly from moving.

[0062] The fine tuning knob is screwed with the bottom wall of the connecting sleeve in the middle part, and one end of the fine tuning knob in the connecting sleeve abuts against the laser radar main panel.

[0063] Specifically, the collision protection device is to install the laser radar on the vehicle body, and since the design and manufacturing precision of the vehicle body cannot meet the high precision requirement of the laser radar, after the laser radar is installed, the position adjustment assembly needs to be adjusted to ensure the assembly precision of the laser radar; the position adjustment assembly comprises a laser radar main panel, a driven nut plate and an active adjusting nut sliding plate, the laser radar main panel plays a role in improving the Z-direction rigidity, a connecting sleeve and a fine tuning knob are arranged below the three-layer plate, the connecting sleeve is connected with the driven nut plates and the active adjusting nut sliding plates on the two sides respectively, and the bottom of the laser radar main panel only abuts against the fine tuning knob; when the fine tuning knob is rotated and adjusted on the connecting sleeve, the connecting sleeve moves up and down relative to the axial direction of the fine tuning knob, so that the connecting sleeve can drive the driven nut plates and the active adjusting nut sliding plates to move in the Z-direction relative to the laser radar main panel, and the laser radar main panel is further connected with the end of the transverse connecting plate, the laser radar is fixed on the driven nut plates and the active adjusting nut sliding plates, so that the adjustment of the laser radar in the Z-direction is realized.

[0064] Optionally, the laser radar main panel is provided with a plurality of long circular holes, the long circular holes are arranged along the Z-direction, and the middle part of the laser radar main panel is provided with a sliding guide groove corresponding to the other end of the connecting assembly.

[0065] Specifically, the laser radar main panel is provided with a plurality of long circular holes, and when the Z-direction adjustment of the laser radar is needed, the driven nut plates and the active adjusting nut sliding plates can set the adjustment amount according to the size of the long circular holes.

[0066] In one embodiment, the size of the long circular hole is 9*13mm, so that the adjustment amount of the laser radar up and down is 4mm, and the size can be designed according to the tolerance and the adjustment amount to offset the assembly tolerance of the front bumper beam assembly and the manufacturing tolerance of the vehicle body.

[0067] Optionally, the driven nut plate is provided with press rivet nuts corresponding to the long round holes, the driving adjustment nut sliding plate is provided with a plurality of mounting holes and a plurality of locking holes, the mounting holes are provided corresponding to the long round holes in the middle of the laser radar main panel, and the locking holes are provided corresponding to the long round holes on both sides of the laser radar main panel.

[0068] Specifically, the driven nut plate is arranged on one side of the laser radar main panel close to the connecting assembly, the driven nut plate is provided with press rivet nuts corresponding to the long round holes, and the press rivet nuts are welded on the driven nut plate to absorb the Z-direction tolerance; the driving adjustment nut sliding plate is arranged on one side of the laser radar main panel close to the laser radar, the driving adjustment nut sliding plate is provided with mounting holes and locking holes, the mounting holes are used to connect the laser radar and the press rivet nuts in the middle of the driven nut plate, and the locking holes are used to connect the driven nut plate and the driving adjustment nut sliding plate into an integrated body; when it is necessary to adjust the Z-direction of the laser radar, the bolts on the mounting holes and the locking holes are loosened, and then the fine adjustment knob is rotated and adjusted; after the position of the laser radar is adjusted, all the bolts are locked.

[0069] In one embodiment, the driven nut plate is provided with a plurality of accommodation feature grooves for avoiding the longitudinal guide ribs.

[0070] Optionally, the laser radar is connected with the press rivet nuts in the middle of the driven nut plate through the first bolt and the laser radar adjustment nut, and the driving adjustment nut sliding plate is connected with the press rivet nuts at both ends of the driven nut plate through the second bolt.

[0071] Specifically, the laser radar adjustment nut is a main connecting component in the field of automotive laser radars, and the laser radar adjustment nut comprises an inner sleeve and an outer sleeve, the inner sleeve can be telescopically moved along the axial direction of the outer sleeve, the inner sleeve is free of internal threads, and the first bolt is arranged in the inner sleeve without radial movement, the laser radar adjustment nut is arranged in the mounting hole of the driving adjustment nut sliding plate and the long round hole of the laser radar main panel, and the end surface of the laser radar adjustment nut abuts against the outer surface of the driven nut plate, the first bolt passes through the inner sleeve of the laser radar adjustment nut and is connected with the press rivet nut in the middle, so that when it is necessary to adjust the up-down movement of the laser radar along the Z-direction, the first bolt is loosened from the press rivet nut, so that there is a space for movement between the driven nut plate and the driving adjustment nut sliding plate, the middle part of the first bolt is limited in the horizontal direction by the long round hole and only moves in the Z-direction; when it is necessary to move the laser radar in the front-back direction, the extension distance of the inner sleeve relative to the outer sleeve of the laser radar adjustment nut is adjusted, so that the front-back fine adjustment of the laser radar is realized; the second bolt connects the driving adjustment nut sliding plate and the press rivet nuts at both ends, so that the laser radar main panel and the driving adjustment nut sliding plate are locked.

[0072] The application further provides an automobile comprising the laser radar collision protection device.

[0073] Specifically, the current automobile has the function of automatic driving, and laser radar needs to be arranged in each direction on the front anti-collision beam assembly, so as to monitor the position of the obstacle and realize avoidance during automatic driving. However, the tolerance caused by the welding of the vehicle body often cannot meet the installation requirements of the laser radar. The laser radar collision protection device can install the laser radar on the vehicle, which can not only ensure the installation accuracy of the laser radar, but also effectively protect the laser radar and reduce the repair cost when the vehicle collides. The laser radar collision protection device keeps the first bolt and the second bolt in a state of being about to be locked after the laser radar is initially positioned, so that the laser radar can still have the possibility of fine adjustment. The front and rear fine adjustment of the laser radar is performed through the laser radar adjusting nut, and the Z-direction position of the laser radar is fine adjusted through the fine adjustment knob. When all the positions of the laser radar are adjusted accurately, the first bolt and the second bolt are locked, so that the positions of the laser radar main panel, the driven nut plate and the driving adjusting nut sliding plate are fixed. Then, the limiting block and the limiting rod are installed on the longitudinal guide rib. No matter when the vehicle is running and bumping or when the vehicle collides with the laser radar and is impacted, the limiting block and the limiting rod protect the laser radar respectively. In the case that the laser radar detects the existence of an obstacle, the laser radar will give a command to the vehicle to slow down. However, when the vehicle still cannot avoid the obstacle after slowing down, the vehicle will hit the obstacle at a very small speed. At this time, the laser radar will be impacted. When the laser radar is impacted, the limiting block is damaged by the position adjusting assembly. The laser radar releases the impact force through displacement. When the position adjusting assembly is in close contact with the limiting rod, the laser radar stops moving, avoiding the collision between the laser radar and the vehicle body sheet metal part, and causing damage to the laser radar.
