Description

Technical Field

[0001] This specification relates to the field of laser radar, and specifically to a radar mounting structure, a laser radar, a radar component and a measurement component. Background Art

[0002] LiDAR is applied to vehicles (such as cars, robots, etc.) to assist vehicles in achieving high-precision positioning, obstacle recognition, and target tracking. Taking vehicles as an example, LiDAR can also assist in maintaining lanes and assist in emergency braking during vehicle driving, and assist in parking when the vehicle is parked.

[0003] LiDAR is usually installed directly on the vehicle. The vehicle often bumps during driving, which causes the LiDAR to vibrate with the bumps of the vehicle, thereby generating vibration noise. At the same time, the vibration of the LiDAR caused by the bumps of the vehicle may also cause the components inside the LiDAR to move or be damaged, resulting in reduced reliability of the LiDAR. The vibration generated by the LiDAR during operation can also be transmitted to the vehicle, causing greater vibration noise inside the vehicle, affecting the comfort of the driver and passengers.

[0004] The contents of the background technology section are merely the technologies known to the public and do not necessarily represent the existing technologies in the field. Utility Model Content

The radar installation structure includes at least one mounting seat. The laser radar is connected to the vehicle through at least one mounting seat. The mounting seat includes a vibration reduction component. The relative vibration or impact energy between the laser radar and the vehicle in the axial and radial directions can be converted into heat energy and deformation energy of the buffer by the deformation of the buffer in the vibration reduction component, thereby playing a role in vibration isolation and buffering, so as to reduce vibration noise and reduce the problem of reduced reliability of the laser radar caused by vibration.

The present application is described in detail below through specific embodiments.

[0049] Figure 1A A front view of a radar installation structure 10 in some embodiments of the present disclosure is shown. Figure 1B Shows Figure 1A The cross-sectional view of the radar installation structure 10 along the AA direction. Figure 1A and Figure 1B As shown, the radar mounting structure 10 includes at least one mounting seat 100. The mounting seat 100 includes a mounting portion 110 and a vibration reduction assembly 130. The mounting portion 110 includes a first mounting hole 111. The vibration reduction assembly 130 includes a buffer 131 and a bushing 133. The buffer 131 is inserted into the first mounting hole 111 and is relatively fixed to the first mounting hole 111 in the axial direction. Both ends of the buffer 131 are located outside the first mounting hole 111. The buffer 131 also includes a second mounting hole 1311. The bushing 133 is inserted into the second mounting hole 1311 and is connected to the buffer 131. Among them, both ends of the bushing 133 are located in the second mounting hole 1311, and both ends of the bushing 133 are located outside the first mounting hole 111.

[0050] In some embodiments, the radar mounting structure 10 may include only one mounting seat 100. In other embodiments, the radar mounting structure 10 may include multiple mounting seats 100. In some embodiments, multiple mounting seats 100 may be connected via a base 150. Figure 1AAs shown, the radar mounting structure 10 may include four mounting seats 100. The four mounting seats 100 may all be connected to the base 150. Among them, the base 150 may be directly or indirectly connected to the laser radar. For example, the base 150 may include a accommodating cavity, and the laser radar may be placed in the accommodating cavity. For another example, the base 150 may be fixedly connected to the laser radar through other structural members. In some embodiments, multiple mounting seats 100 may be separately arranged, and multiple mounting seats 100 may be directly or indirectly connected to the laser radar. For example, the mounting seat 100 may be bonded to the laser radar. For another example, the mounting seat 100 may be fixedly connected to the laser radar through other structural members.

[0051] The mounting portion 110 is a component of the radar mounting structure 10 for connecting to a vehicle. The vibration reduction assembly 130 is a component for achieving vibration reduction and buffering. The vibration reduction assembly 130 can be mounted on the mounting portion 110, and the buffer member 130 in the vibration reduction assembly 130 has a buffering effect. The vehicle can be connected to the laser radar through the vibration reduction assembly 130, and vibration reduction between the laser radar and the vehicle can be achieved.

[0052] Figure 2 A front view of the mounting portion 110 in some embodiments of the present disclosure is shown. The mounting portion 110 includes a first mounting hole 111. The first mounting hole 111 is used to mount the vibration reduction assembly 130. The first mounting hole 111 is a through hole that penetrates the mounting portion 110. The cross-sectional shape of the first mounting hole 111 can be any shape. For example, circular, square, oval, and so on. The material of the mounting portion 110 can be any material, such as metal material, polymer material, and so on. The mounting portion 110 may include a side wall 113. The side wall 113 is the end of the mounting portion in the axial direction.

[0053] The buffer 131 can be installed and fixed in the first mounting hole 111. Specifically, the outer surface of the portion of the buffer 131 that passes through the first mounting hole 111 abuts against the surface of the first mounting hole 111 and is relatively fixed to the first mounting hole 111 in the axial direction. There are many different ways to fix the buffer 131 to the first mounting hole 111.

[0054] Figure 3A FIG. 1 shows a half-section view of a buffer member 131 in some embodiments of the present disclosure. Figure 3A The buffer member 131 shown is defined as 131A. In some embodiments, the buffer member 131A can be glued to the hole wall of the first mounting hole 111 to achieve its fixation in the axial direction. In some embodiments, a fixing groove ( Figure 3A ), and the other may be provided with a protrusion ( Figure 3AThe shapes and sizes of the protrusions and the fixing grooves match each other. The protrusions and the fixing grooves can be distributed continuously or independently at intervals. When the buffer 131 is installed in the first mounting hole 111, the protrusions are inserted into the fixing grooves, so that the buffer 131 and the first mounting hole 111 are relatively fixed in the axial direction.

[0055] In other embodiments, the buffer member 131 can be fixed in the axial direction by setting a limiting portion to prevent the buffer member 131 from moving in the axial direction. Figure 3B FIG. 1 shows a half-section view of another buffer member 131 in some embodiments of the present disclosure. Figure 3B The illustrated buffer 131 is defined as 131B. Figure 3C Shows Figure 3B sectional view of the connection between the buffer member 131B and the mounting portion 110. Figure 3B and 3C As shown, the buffer member 131B includes a connecting portion 1313 and a limiting portion 1315. The connecting portion 1313 is inserted into the first mounting hole 111. The outer surface of the connecting portion 1313 can abut against the surface of the first mounting hole 111. The limiting portion 1315 is located at both ends of the connecting portion 1313. And the limiting portion 1315 is located outside the first mounting hole 111. Among them, the limiting portion 1315 can abut against the side wall 113 of the mounting portion 110.

[0056] The buffer 131B is in an I-shape as a whole, and wraps a part of the mounting portion 110. After the limiting portion 1315 abuts against the side wall 113 of the mounting portion 110, the movement of the buffer 131 in the axial direction will be blocked by the mounting portion 110, so that the buffer 131 and the first mounting hole 111 are relatively fixed in the axial direction.

[0057] In some embodiments, the connection portion 1313 and the limiting portion 1315 may be an integrated structure. The buffer may be fixed in the first mounting hole 111 in a variety of ways. For example, the buffer 131B may be formed and fixed at and around the first mounting hole 111 by a rubber encapsulation process. For another example, a molded buffer may be installed in and around the first mounting hole. In some embodiments, the connection portion 1313 and the limiting portion 1315 may be a detachable structure. At this time, the connection portion 1313 may be first installed in the first mounting hole 111, and the limiting portion 1315 may be connected to the connection portion 1313. For example, the limiting portion 1315 is connected to the connection portion 1313 by bonding. For another example, the limiting portion 1315 is connected to the connection portion 1313 by an interference fit.

[0058] like FIG. 3A to FIG. 3CAs shown, the buffer 131 may further include a second mounting hole 1311. The second mounting hole 1311 may be used to mount the bushing 133. The central axis of the second mounting hole 1311 may be coaxial or parallel to the central axis of the first mounting hole 111. The cross-sectional shape of the second mounting hole 1311 may be any shape. For example, circular, square, elliptical, and so on. In some embodiments, the second mounting hole 1311 may be a through hole that penetrates the buffer 131. In some embodiments, the second mounting hole 1311 may be a non-through hole.

[0059] In some embodiments, the material of the buffer 131 may include a damping material. A damping material is a material that can convert the mechanical vibration energy of a solid into heat energy for dissipation, and can be used for vibration reduction and noise control.

[0060] The material of the buffer 131 is damping material that can absorb the vibration from the laser radar and the vibration from the vehicle and convert it into deformation of the buffer 131, thereby achieving the effect of vibration reduction, reducing vibration noise, and reducing the problem of reduced reliability of the laser radar caused by vibration.

[0061] In some embodiments, the buffer 131 may include foam plastic. In other embodiments, the buffer 131 may include rubber. For example, the buffer 131 may be silicone rubber. For another example, the buffer 131 may be butyl rubber. In other embodiments, the buffer 131 may include a combination of multiple damping materials. For example, a combination of rubber and foam plastic. This specification does not limit the material of the buffer 131. The buffer 131 has feasible deformation in any direction.

[0062] When the laser radar is connected to the vehicle through the radar mounting structure 10. The bushing 133 is used to limit the position when the vehicle is connected to the radar mounting structure 10. The outer surface of the bushing 133 abuts against the surface of the second mounting hole 1311 to achieve connection. In some embodiments, in the axial direction, the size of the bushing 133 can be equal to the size of the second mounting hole 1311 and larger than the size of the first mounting hole 111. In some embodiments, in the axial direction, the size of the bushing 133 can be smaller than the size of the second mounting hole 1311 and larger than the size of the first mounting hole 111. Figure 4 Shows Figure 1B A partial enlarged view I of the radar mounting structure 10 is provided. Figure 1B and Figure 4 As shown, in the axial direction, the size of the bushing 133 is smaller than the size of the second mounting hole 1311, and larger than the size of the first mounting hole 111. Through the above structure, after the radar mounting structure 10 is assembled with the vehicle, the vehicle connection part can abut against the buffer 131, so that the vibration can be better transmitted to the buffer.

[0063] In some embodiments, the difference between the size of the bushing 133 in the axial direction and the size of the second mounting hole 1311 should be within a preset range, so that after the vehicle and the radar mounting structure 10 are assembled, the compression of the buffer 131 is less than the maximum compression allowed by the buffer 131. The buffer 131 can also be deformed under the action of vibration, thereby playing a role in vibration reduction. In some embodiments, the selection of the preset range is related to the material of the buffer 131. The smaller the elastic modulus of the material, the smaller the difference. In some embodiments, the selection of the preset range is related to the amplitude of the relative vibration between the vehicle and the laser radar. The larger the amplitude, the smaller the difference.

[0064] Figure 5 FIG. 1 shows a half-section view of the bushing 133 in some embodiments of the present disclosure. Figure 5 As shown, the bushing 133 may include a third mounting hole 1331. The third mounting hole 1331 is a through hole that penetrates the bushing 133. The central axis of the third mounting hole 1331 may be coaxial with the central axis of the first mounting hole 111, or may be arranged in parallel. The third mounting hole 1331 may be used for connecting the radar mounting structure 10 with the vehicle. The portion of the vehicle used for connecting with the radar mounting structure 10, that is, the vehicle connecting component may pass through the third mounting hole 1331 and be fixedly connected with the radar mounting structure. In other embodiments, the vehicle connecting component may be a clamp, and the clamp may clamp both ends of the bushing 133 to achieve the connection between the vehicle and the radar mounting structure 10. When the laser radar is connected to the vehicle through the radar mounting structure 10, the vehicle connecting component abuts against both ends of the bushing 133. Because the two ends of the bushing 133 are located outside the first mounting hole 111 and inside the second mounting hole 1311, after the vehicle is connected to the radar mounting structure 10, the vehicle connecting component also abuts against both ends of the buffer 131. The limiting function of the bushing 133 ensures that the buffer 131 remains in a deformable state after installation. When the vehicle or the laser radar vibrates, the vibration can be transmitted to the buffer 131 to achieve vibration reduction between the vehicle and the laser radar, reduce vibration noise, and reduce the problem of reduced reliability of the laser radar caused by vibration.

[0065] In some embodiments, the material of the bushing 133 includes a rigid material. For example, the material of the bushing 133 may be metal or alloy. For example, the material of the bushing 133 may be stainless steel. For another example, the material of the bushing 133 may be ceramic. For another example, the material of the bushing 133 may be a polymer material.

[0066] Since the bushing 133 can be made of rigid material, it is not easy to deform. When the laser radar is installed on the vehicle through the radar installation structure 10, the bushing 133 can be used for installation and positioning. The bushing 133 can ensure that the spacing of the vehicle connection components meets the requirements, so that the buffer 131 is not completely compressed after the radar installation structure 10 is installed on the vehicle, and is still in a deformable state to absorb the impact energy caused by mechanical movement, so as to perform vibration isolation and buffering.

[0067] Figure 6 A cross-sectional view of a vibration reduction assembly in some embodiments of the present disclosure is shown. For ease of description, Figure 6 The buffer member 131 shown in FIG. Figure 3B The buffer member 131B in FIG. Figure 6 As shown, the bushing 133 can be installed in the second mounting hole 1311. In some embodiments, the bushing 133 can be fixed in the second mounting hole 1311 by a rubber encapsulation process. In some embodiments, the bushing 133 can be connected to the second mounting hole 1311 by bonding, welding, seam connection, riveting, etc.

[0068] In some embodiments, one of the surface of the second mounting hole 1311 and the outer surface of the bushing 133 is provided with a positioning boss 1312, and the other is provided with a positioning groove 1335. The positioning groove 1335 matches the positioning boss 1312. The above structure can improve the stability of the connection between the bushing 133 and the second mounting hole 1311.

[0069] In some embodiments, the surface of the second mounting hole 1311 may be provided with a positioning protrusion 1312 (eg, FIG. 3A to FIG. 3C as well as Figure 6 The outer surface of the bushing 133 may be provided with a positioning groove 1335 (as shown); Figure 5 and Figure 6 In some embodiments, a positioning groove 1335 may be provided on the surface of the second mounting hole 1311 ; and a positioning protrusion 1312 may be provided on the outer surface of the bushing 133 .

[0070] The extending direction of the positioning groove 1335 and the positioning protrusion 1312 can be any direction that is not parallel to the central axis of the second mounting hole 1311. In some embodiments, the extending direction of the positioning groove 1335 and the positioning protrusion 1312 can be the circumferential direction of the second mounting hole 1311. Among them, the positioning groove 1335 and the positioning protrusion 1312 can surround the buffer 131 and the bushing 133 for a complete circle, or they can not surround the complete circle. The positioning groove 1335 and the positioning protrusion 1312 surround the buffer 131 and the bushing 133 in the circumferential direction continuously, or they can surround at intervals. In some embodiments, the positioning groove 1335 and the positioning protrusion 1312 can extend along the buffer 131 and the bushing 133 along a spiral line.

[0071] The positioning groove 1335 matches the positioning boss 1312. When the bushing 133 is installed in the second mounting hole 1311, the positioning boss 1312 is inserted into the positioning groove 1335, thereby fixing the bushing 133 and the second mounting hole 1311 in the axial direction.

[0072] By providing the positioning groove 1335 and the positioning protrusion 1312, the buffer 131 and the bushing 133 can be matched more closely and fixed more firmly. In particular, when the bushing 133 is fixed to the inner side of the buffer 131 through the rubber coating process, providing the positioning groove 1335 and the positioning protrusion 1312 on the surface of the buffer 131 and the bushing 133 can facilitate the rubber coating injection molding, so that the bushing 133 and the buffer 131 are fastened.

[0073] In some embodiments, at least one of the surface of the second mounting hole 1311 and the outer surface of the bushing 133 is provided with a knurled structure. For example, the surface of the second mounting hole 1311 is provided with a knurled structure. For another example, the outer surface of the bushing 133 is provided with a knurled structure. For another example, the surface of the second mounting hole 1311 and the outer surface of the bushing 133 are both provided with a knurled structure.

[0074] By providing a knurling structure on the surface of the second mounting hole 1311 and / or the outer surface of the bushing 133, the bushing 133 and the buffer 131 can be matched more closely and fixed more firmly. In particular, when the bushing 133 is fixed to the inside of the buffer 131 through the rubber coating process, providing a knurling structure on the surface of the buffer 131 and / or the bushing 133 can facilitate the rubber coating injection molding, so that the bushing 133 and the buffer 131 are fastened.

[0075] This specification also provides a laser radar 20. Figure 7 A schematic diagram of the structure of a laser radar 20 is shown. The laser radar 20 may include a transmitting system and a receiving system. Among them, the transmitting system may include a laser transmitter. The laser transmitter may transmit a detection signal (laser). The receiving system may include a laser receiver. After the laser emitted by the laser transmitter irradiates the surface of an object, it will be reflected by the object to form an echo signal. The corresponding echo signal can be received by the laser receiver and used to obtain the spatial position information of the obstacle. The laser radar 20 also includes a housing 220. The housing 220 includes a radar mounting structure 10.

[0076] The shell 220 can be the mounting base of the laser radar 20. Other components of the laser radar 20 (such as the transmitting system and the receiving system) can be installed with the shell 220 as a carrier. The shape of the shell 220 can be any shape to adapt to the installation of other components and to meet the measurement requirements. The material of the shell 220 can be any material, such as metal, plastic, polymer, rubber, and so on. This specification does not limit the shape and material of the shell 220. The integral molding of the shell 220 and the radar mounting structure 10 can not only increase the strength, but also reduce the overall volume of the laser radar 20, making the laser radar 20 smaller and more compact, and suitable for installation in more scenes or spaces. In some embodiments, the radar mounting structure 10 can be integrally molded on the shell 220 of the laser radar. In some embodiments, the radar mounting structure 10 can be fixed on the outer shell of the laser radar to form the shell 220 of the laser radar.

[0077] This specification also provides a radar assembly 30 . Figure 8 FIG. 2 shows a schematic diagram of the structure of a radar assembly 30 in some embodiments of the present disclosure. Figure 8 As shown, the radar assembly 30 may include a radar mounting structure 10 and a laser radar 40. The radar mounting structure 10 may be fixedly connected to the laser radar 40.

[0078] The laser radar 40 may include a transmitting system and a receiving system. The transmitting system may include a laser transmitter. The laser transmitter may transmit a detection signal (laser). The receiving system may include a laser receiver. After the laser emitted by the laser transmitter irradiates the surface of an object, it will be reflected by the object to form an echo signal. The corresponding echo signal can be received by the laser receiver and used to obtain the spatial position information of the object.

[0079] The radar mounting structure 10 can be fixedly connected to the laser radar 40 in a number of ways, including but not limited to: threaded connection, welding, bonding, riveting, snap-on connection, and the like.

[0080] In some embodiments, the number of at least one mounting seat 100 in the radar mounting structure is multiple. The multiple mounting seats 100 can be distributed on both sides of the laser radar 40. For example, Figure 8 As shown, the radar mounting structure 10 may include four mounting seats 100. The four mounting seats 100 are distributed on two sides adjacent to the window. Further, multiple mounting seats 100 may be evenly distributed on the two sides, so that the laser radar 40 is evenly stressed when being fixed, and is more stable.

[0081] This specification also provides a measurement component 50 . Fig. 9 FIG. 5 shows a schematic diagram of the structure of a measurement component 50 in some embodiments of the present disclosure. Fig. 9As shown, the measuring assembly 50 includes a radar assembly 30, a bracket 60 and a connecting member 70. The radar assembly 30 can be understood as the aforementioned Figure 8 The corresponding embodiment provides a radar assembly 30. The bracket 60 includes a first mounting portion 61 and a second mounting portion 63. The first mounting portion 61 is configured to be connected to a carrier. The second mounting portion 63 is configured to be connected to the radar assembly 30. The connecting member 70 is connected to the second mounting portion 63 and the buffer member 131. Both ends of the bushing 133 are respectively in contact with the connecting member 70 and the second mounting portion 63.

[0082] The connector 70 is a component used for connection. The connector 70 can fix the radar assembly 30 and the bracket 60. The bracket 60 can fix the radar assembly 30 on a carrier. The carrier can be a vehicle, an airplane, a ship, a robot, and the like. For example, the bracket 60 can fix the radar assembly 30 on the top of a vehicle. For another example, the bracket 60 can fix the radar assembly 30 behind the windshield of the vehicle. The material of the bracket 60 can be any material, such as plastic material, metal material, polymer material, rubber material, and the like. The shape of the bracket 60 can be any shape to meet the installation requirements. This specification does not limit the shape and material of the bracket 60.

[0083] By using the bracket 60 to fix the radar assembly 30 on the carrier, a more flexible installation position can be provided for the radar assembly 30, so that the radar assembly 30 can be suitable for carriers with different installation requirements or different detection requirements.

[0084] Fig.10 The structure diagram of a bracket 60 in some embodiments of the present disclosure is shown. The bracket 60 includes a first mounting portion 61 and a second mounting portion 63 .

[0085] The first mounting portion 61 is configured to be connected to a vehicle. For example, the first mounting portion 61 can be connected to the vehicle by bonding, welding, seaming, riveting, etc., which are not limited in this specification. As mentioned above, the bracket 60 can fix the radar assembly 30 behind the windshield of the vehicle.

[0086] The second mounting portion 63 is configured to be connected to the radar assembly 30, so as to fix the radar assembly 30 on the carrier. Fig.10 As shown, the second mounting portion 63 may include a connecting hole 631 for fixedly connecting with the connecting member 70 , thereby fixing the radar assembly 30 on the bracket 20 .

[0087] In some embodiments, the second mounting portion 63 may be a mounting post connected to the first mounting portion 61. Fig. 9As shown, the second mounting portion 63 may include four mounting posts to correspond to the four mounting seats 100 of the radar mounting structure 10. A connecting hole 631 may be formed on the end surface of each mounting post to correspond to the second mounting hole 1311 of the radar mounting structure 10.

[0088] Fig.11A Shows Fig. 9 A cross-sectional view of the measurement assembly 50 along the section CC is provided. Fig. 11B Shows Fig.11A A partial enlarged view J of the measurement assembly 50 is provided. Fig.11A and 11B As shown, the connecting member 70 can be inserted into the third mounting hole 1331 and fixedly connected to the connecting hole 631. Both ends of the bushing 133 abut against the connecting member 70 and the second mounting portion 63. Both ends of the buffer member 131 abut against the connecting member 70 and the second mounting portion 63.

[0089] As mentioned above, in the axial direction, the size of the bushing 133 is smaller than the size of the second mounting hole 1311, and larger than the size of the first mounting hole 111. This allows the connection member 70 and the bracket 60 to contact the buffer 131 in the axial direction when the radar mounting structure 10 is connected to the connection member 70 and the bracket 60, and the second mounting portion 63 and the radar mounting structure 10 (mounting portion 110) are spaced apart in the axial direction to ensure that the buffer 131 is deformable in the axial direction, so that the mechanical vibration can be released by the buffer 131 after being transmitted to the buffer 131, thereby playing a vibration reduction role.

[0090] In some embodiments, the connecting member 70 may be a bolt. The thread of the bolt is adapted to the internal thread of the connecting hole 631. The bolt may include a screw and a pan head. The screw may be sequentially inserted into the third mounting hole 1331 and the connecting hole 631 and fastened to the connecting hole 631. The pan head of the bolt may contact the bushing 133 to limit the extent to which the pan head of the bolt compresses the buffer 131 in the axial direction.

[0091] In other embodiments, the connector 70 may be a buckle, and the second mounting portion 63 may be a slot adapted to the buckle or provided with a slot adapted to the buckle. The radar assembly 30 may be fixed to the bracket 20 by the buckle and the slot being engaged. The buckle and the slot may abut against both ends of the bushing 133, respectively, to limit the degree to which the buckle and the slot compress the buffer 131 in the axial direction. In other embodiments, the connector 70 may be a slot, and the second mounting portion 63 may be a buckle adapted to the slot.

[0092] When the laser radar 40 is installed on the vehicle through the radar installation structure 10, the bushing 133 can be used for installation and positioning, so that the buffer 131 is still in a deformable state after the laser radar 40 is installed on the vehicle, and the vibration of the vehicle and the laser radar 40 can be transmitted to the buffer 131, thereby achieving vibration isolation and buffering of the vehicle and the laser radar 40. The vibration in the axial and radial directions or the impact energy received is converted into the heat energy and deformation energy of the buffer 131 through the deformation of the buffer 131, thereby playing the role of vibration isolation and buffering, thereby reducing vibration noise and reducing the problem of reduced reliability of the laser radar 40 caused by vibration.
