[0016] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

Conventional structures or constructions will be omitted where they may cause confusion in understanding the utility model. It should be noted that the shapes and dimensions of the components in the figures do not reflect actual size and proportion, but are only schematic representations of the contents of the embodiments of this utility model.

[0017] Unless otherwise defined, the technical or scientific terms used in the embodiments of this utility model shall have the ordinary meaning as understood by those skilled in the art. The terms "first," "second," and similar terms used in the embodiments of this utility model do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

[0018] Figure 1 A schematic diagram of the structure of a lidar device according to an embodiment of the present invention is shown.

[0019] like Figure 1 As shown, the lidar device 100 includes a mounting bracket 1, a lidar 2, two fixed brackets 3, and two connecting components 4.

[0020] In an embodiment of this invention, the mounting bracket 1 includes a first sub-part 11 and two second sub-parts 12. The two second sub-parts 12 are disposed opposite each other on both sides of the first sub-part 11 along a first direction X. The first sub-part 11 and the two second sub-parts 12 form a recess 13. A lidar 2 is fixedly mounted in the recess 13. The lidar 2 is configured to emit radio waves in a specific direction. The lidar 2 is located on one side of the first sub-part 11 in the Z direction.

[0021] The recess 13 formed by the first sub-part 11 and the two second sub-parts 12 can restrict the movement of the lidar 2 in the first direction X. The two second sub-parts 12 are located on both sides of the lidar 2 along the first direction X, so that the lidar 2 can be in a stable and non-shifting state in the first direction X.

[0022] In an embodiment of this utility model, two fixed supports 3 are respectively located below two second sub-parts 12. The second sub-parts 12 are located on one side of the fixed supports 3 in the Z direction. Two connecting parts 4 elastically connect the two second sub-parts 12 to the fixed supports 3 below them respectively. The two second sub-parts 12 are elastically connected to the two fixed supports 3 respectively.

[0023] Since the two second sub-parts 12 are located on opposite sides of the lidar 2 in the first direction X, the two fixed brackets are also located on opposite sides of the lidar 2 in the first direction X, and the two connecting parts 4 are also located on opposite sides of the lidar 2 in the first direction X. Because the lidar 2 has the same structure and the same connection method on both sides in the first direction X, the lidar 2 can maintain balance in the first direction X.

[0024] For example, the mounting bracket 3 can be fixedly mounted on an external device to secure the lidar device 100 to the external device. When the external device moves the mounting bracket 3, the lidar device 100 can move along with the external device.

[0025] When the external device vibrates, the fixed bracket 3 will also vibrate along with it. In this case, the mounting bracket 1 will shift relative to the fixed bracket 3. For example, the mounting bracket 1 may shift in the Z direction. With the buffering effect of the connecting component 4, the shift of the mounting bracket 1 can be controlled within a small range.

[0026] If the displacement of the second sub-part 12 on the right side of the lidar 2 relative to the fixed bracket 3 below it differs from the displacement of the second sub-part 12 on the left side of the lidar relative to the fixed bracket 3 below it, the mounting bracket 1 will tilt in the first direction X. This causes a change in the direction of the radio waves emitted by the lidar 2, resulting in a shift in the azimuth detected by the lidar 2.

[0027] Under the combined action of the two connecting parts 4, the displacement of the second sub-part 12 on the right side of the lidar 2 relative to the fixed bracket 3 below it is similar to the displacement of the second sub-part 12 on the left side of the lidar relative to the fixed bracket 3 below it, and the mounting bracket 1 will remain balanced in the first direction X. This keeps the direction of the radio waves generated by the lidar 2 stable, thereby ensuring that the detection azimuth of the lidar 2 is stable and does not deviate.

[0028] In an embodiment of this utility model, the connecting component 4 includes a plurality of elastic elements arranged sequentially along the second direction Y. The plurality of elastic elements are configured to control the offset of the lidar 2 relative to the fixed support 3 when the fixed support 3 vibrates, so as to control the direction of the lidar 2 emitting radio waves.

[0029] The first direction X intersects the second direction Y. For example, the angle between the first direction X and the second direction Y can be 90°, 89°, and 91°. This invention does not limit the angle between the first direction X and the second direction Y.

[0030] With the buffering effect of multiple elastic elements, the displacement of the mounting bracket 1 relative to the fixed bracket 3 along the Z direction can be controlled within a small range. Since multiple elastic elements are arranged sequentially along the second direction Y, the second sub-part 12 can maintain balance in the second direction Y.

[0031] For example, if the second sub-part 12 is displaced relative to the fixed bracket 3 below it along the Z direction, the displacements of the two ends of the second sub-part 12 along the second direction Y may be different. In this case, the mounting bracket 1 will tilt in the second direction Y. This causes a change in the direction of the radio waves emitted by the lidar 2, resulting in a shift in the azimuth detected by the lidar 2.

[0032] Under the combined action of multiple elastic elements arranged sequentially along the second direction Y, the two ends of the second sub-part 12 along the second direction Y are displaced approximately the same relative to the fixed bracket 3 below it, and the mounting bracket 1 remains balanced in the second direction Y. This keeps the direction of the radio waves generated by the lidar 2 stable, thereby ensuring that the azimuth detected by the lidar 2 is stable and does not deviate.

[0033] In this embodiment of the invention, the lidar 2 maintains balance in the first direction X under the combined action of the two connecting components 4, reducing displacement differences in the first direction X. Similarly, the lidar 2 maintains balance in the second direction Y under the combined action of multiple elastic members arranged along the second direction Y, reducing displacement differences in the second direction Y. In this configuration, the lidar 2 can maintain a state of emitting radio waves in a specific direction during operation, ensuring detection accuracy.

[0034] Combination Figure 2 , Figure 3 and Figure 4 A schematic description of the lidar device 100 is provided. Figure 2 A schematic diagram of a lidar device according to another embodiment of the present invention is shown. Figure 3 An exploded structural diagram of a lidar device according to an embodiment of the present invention is shown. Figure 4 A cross-sectional schematic diagram of a lidar device according to an embodiment of the present invention is shown.

[0035] like Figure 2 As shown, the connecting component 4 includes multiple elastic elements, including a spring 41 and two rubber pillars 42. The connecting component 4 also includes a first connector 43 and two second connectors 44.

[0036] In this embodiment of the invention, one end of the spring 41 is located in the limiting part 31 of the fixed bracket 3 and abuts against the upper surface of the fixed bracket 3. The other end of the spring 41 extends out of the upper surface of the second sub-part 12 through the first through hole 121 of the second sub-part 12. Two rubber pillars 42 are arranged opposite to each other on both sides of the spring 41 along the second direction Y. The rubber pillars 42 abut against the lower surface of the second sub-part 12 and extend into the second through hole 32 of the fixed bracket 3.

[0037] The limiting part 31 can be located in the middle of the fixed bracket 3, and one end of the spring 41 is located in the limiting part 31. The limiting part 31 can restrict the position of the spring 41 so that during the displacement of the second sub-part 12 relative to the fixed bracket 3, the end of the spring 41 located in the limiting part 31 remains stable and does not shift.

[0038] The first through hole 121 can also be located in the middle of the second sub-part 12. For example, the orthographic projection of the first through hole 121 onto the lower fixing bracket 3 can at least partially overlap with the limiting part 31. The other end of the spring 41 is located in the first through hole 121, which can limit the position of the spring 41 so that during the displacement of the second sub-part 12 relative to the fixing bracket 3, the end of the spring 41 located in the first through hole 121 remains stable and does not shift.

[0039] The spring 41 is in the limiting part 31 and abuts against the upper surface of the fixed bracket 3. Therefore, the spring 41 can deform in the direction from the second sub-part 12 to the fixed bracket 3, thereby providing a buffering effect on the second sub-part 12.

[0040] In an embodiment of this utility model, two second through holes 32 are disposed opposite to each other on both sides of the limiting part 31 along the second direction Y. The rubber column 42 extends into the second through hole 32, and the second through hole 32 can limit the position of the rubber column 42, so that during the displacement of the second sub-part 12 relative to the fixed bracket 3, the portion of the rubber column 42 located in the second through hole 32 remains stable and does not shift.

[0041] The rubber column 42 abuts against the lower surface of the second sub-part 12. During the displacement of the second sub-part 12 relative to the fixed bracket 3, the rubber column 42 can support the second sub-part 12 to provide a supporting force to the second sub-part 12 away from the fixed bracket 3, thereby playing a buffering role for the second sub-part 12.

[0042] The spring 41 is located in the middle of the second sub-section 12 and provides the main cushioning effect for the second sub-section 12. The two rubber pillars 42 are located at both ends of the second sub-section 12 along the second direction Y, providing support for the two ends of the second sub-section 12 along the second direction Y and providing auxiliary cushioning effect for the second sub-section 12.

[0043] In this embodiment of the invention, a composite structure formed by a spring 41 and a rubber column 42 is used to dampen the vibration of the mounting bracket 1 and improve the stability of the lidar 2. The spring 41 can store kinetic energy. When the lidar device 100 passes over complex road surfaces, the spring 41 can convert the large swings of the mounting bracket 1 into small-amplitude, high-frequency vibrations, thereby reducing the vibration amplitude of the lidar 2 and achieving a damping effect. The rubber column 42 absorbs the energy of the lidar 2's shaking through deformation, allowing the lidar 2 to stop quickly. The deformation direction of the rubber column 42 is unrestricted and can adapt to lidar 2 shaking in different directions.

[0044] The composite damping mechanism, employing both spring 41 and rubber column 42, can reduce vibration amplitude to meet complex road conditions, while also providing rapid vibration damping for the lidar 2 via the rubber column 42. Specifically, the spring 41 quickly reduces the vibration amplitude, while the rubber column 42 simultaneously absorbs high-frequency vibrations. In this configuration, the rubber column 42 exhibits minimal deformation; the spring 41 absorbs axial vibrations, while the rubber column 42 absorbs multi-directional vibrations. The combined use of spring 41 and rubber column 42 extends the individual lifespan of both, thereby extending the overall lifespan of the lidar device 100.

[0045] like Figure 3 and Figure 4As shown, the lidar 2 is fixed to the mounting bracket 1. For example, the mounting bracket 1 has positioning holes through which the lidar 2 is fixedly mounted.

[0046] The first connector 43 connects the second sub-part 12 and the fixed bracket 3 through the first through hole 121 of the second sub-part 12 and the third through hole 33 of the fixed bracket 3. The spring 41 is sleeved on the first connector 43. The two second connectors 44 connect the second sub-part 12 and the rubber pillar 42 through the fourth through hole 122 of the second sub-part 12 and the limiting hole 421 of the rubber pillar 42.

[0047] The first through hole 121 and the third through hole 33 are coaxial with the limiting part 31. The orthographic projection of the first through hole 121 on the fixed bracket 3 can at least partially overlap with the third through hole 33. The fourth through hole 122 is coaxial with the second through hole 32, and the two fourth through holes 122 are arranged opposite each other on both sides of the first through hole 121 along the second direction Y. The orthographic projection of the fourth through hole 122 on the fixed bracket 3 can at least partially overlap with the second through hole 32.

[0048] The first connector 43 passes through the first through hole 121 and the third through hole 33 to connect the fixed bracket 3 and the mounting bracket 1. The spring 41 is sleeved on the first connector 43, which can guide the deformation direction of the spring 41, so that the spring 41 deforms along the Z direction without deviating towards the first X direction and the second Y direction.

[0049] The second connector 44 passes through the fourth through hole 122 and the limiting hole 421 to connect the rubber column 42 and the mounting bracket 1. The rubber column 42 is then connected to the fixing bracket through the second through hole 32. Therefore, the second connector 44 and the rubber column 42 can connect the fixing bracket 3 and the mounting bracket 1.

[0050] In an embodiment of this utility model, at the connection point of the first connector 43, the first connector 43 fixes the spring 41 to the fixed bracket 3 and the mounting bracket 1, so that the spring 41 provides cushioning between the fixed bracket 3 and the mounting bracket 1. At the connection point of the second connector 44, the second connector 44 fixes the rubber post 42 to the fixed bracket 3 and the mounting bracket 1, so that the rubber post 42 provides cushioning between the fixed bracket 3 and the mounting bracket 1.

[0051] For example, the first connector 43 and the second connector 44 can be screws. The first through hole 121, the third through hole 33, the fourth through hole 122 and the limiting hole 421 can be provided with threads to fix the first connector 43 and the second connector 44.

[0052] In an embodiment of the present invention, the first sub-part 11 includes a mounting plane 111, wherein the edge extending along the second direction Y in the mounting plane 111 forms an angle with the second direction Y at a preset angle, and the mounting plane 111 is configured to define the orientation of the laser radar 2 emitting radio waves.

[0053] like Figure 4 As shown, the fixed bracket 3 is installed in the horizontal plane formed by the first direction X and the second direction Y, and the lidar 2 is tilted at a preset angle relative to the horizontal plane.

[0054] The mounting plane 111 is tilted relative to the horizontal plane formed by the first direction X and the second direction Y, so that the lidar 2 is also tilted relative to the horizontal plane, thereby controlling the direction of the radio waves emitted by the lidar 2.

[0055] For example, the preset angle can be 10°. LiDAR 2 is also placed at a 10° tilt. Because LiDAR 2 is not horizontally placed, its field of view can cover areas in more directions, enabling detection of a wider area.

[0056] By changing the tilt angle of the mounting plane 111, the direction of the radio waves emitted by the lidar 2 can be changed to meet different detection requirements. For example, by changing the mounting plane 111 with different tilt angles, multi-angle detection by the lidar 2 can be achieved.

[0057] In this embodiment of the invention, a composite damping structure is formed by the spring 41 and the rubber column 42, which reduces the cost of the damping structure in the lidar device 100 and combines the advantages of both the spring 41 and the rubber column 42. Furthermore, by adjusting the hardness of the rubber column 42, it can be adapted to various application scenarios of the lidar device 100.

[0058] Combination Figure 4 , Figure 5A and Figure 5B A schematic description of the lidar device 100 is provided. Figure 5A A schematic diagram of the structure of a rubber column according to an embodiment of the present invention is shown. Figure 5B A cross-sectional schematic diagram of a rubber column according to an embodiment of the present invention is shown.

[0059] like Figure 5A As shown, the rubber column 42 includes a rubber column body 422 and a connecting column 423. The rubber column body 422 and the connecting column 423 are coaxial and integrally formed.

[0060] Combination Figure 4 The connecting post 423 is disposed in the second through hole 32 of the fixed bracket 3. The upper surface of the rubber post body 422 abuts against the lower surface of the second sub-part 12, and the lower surface of the rubber post body 422 abuts against the upper surface of the fixed bracket 3.

[0061] In this embodiment of the invention, the rubber column body 422 is located between the second sub-part 12 and the fixed bracket 3. The upper surface of the rubber column body 422 abuts against the lower surface of the second sub-part 12, and the lower surface of the rubber column body 422 abuts against the upper surface of the fixed bracket 3. The rubber column body 422 provides support for the second sub-part 12 and the fixed bracket 3. During the displacement of the second sub-part 12 relative to the fixed bracket 3, the rubber column body 422 can support the second sub-part 12, providing a supporting force away from the fixed bracket 3, thereby buffering the second sub-part 12.

[0062] like Figure 5A and Figure 5B As shown, a limiting hole 421 is formed on the upper surface of the rubber column body 422, and a cavity 4221 is formed inside the rubber column body 422. The limiting hole 421, the cavity 4221 and the connecting column 423 are coaxial, and the limiting hole 421 and the cavity 4221 are connected.

[0063] The limiting hole 421 is used to limit the second connector 44, so that the second connector 44 and the rubber column body 422 are stably connected. The cavity 4221 is located in the central part of the rubber column body 422. The limiting hole 421, the cavity 4221 and the connecting column 423 are coaxial, so that the rubber column 42 is symmetrical about the central axis, thereby making the rubber column 42 deform uniformly in the axial direction and improving the stability of the rubber column 42.

[0064] In an embodiment of this utility model, a plurality of grooves 4223 are provided on the sidewall 4222 of the rubber column body 422. The plurality of grooves 4223 extend along the axial direction of the rubber column body 4222 and are arranged around the cavity 4221. The plurality of grooves 4223 and the cavity 4221 are independent of each other.

[0065] The cavity 4221 inside the rubber column body 422 and the multiple grooves 4223 on the outside form a double-layer cavity structure. Through the cooperation of the inner and outer layers, the vibration energy generated by the mounting bracket 1 can be absorbed step by step. Among them, high-frequency small-amplitude vibrations can be mitigated by the multiple grooves 4223 on the outside, while low-frequency large-amplitude impacts can be absorbed by the compression deformation of the cavity 4221 inside, thereby reducing the vibration of the lidar 2.

[0066] The cavity 4221 is isolated from the multiple grooves 4223 by an annular structure, making the multiple grooves 4223 independent and not connected to the cavity 4221. The cavity 4221 can provide space to accommodate the deformation of the grooves 4223, and the grooves 4223 can also provide space to accommodate the deformation of the cavity 4221. The annular structure can also provide support for the rubber column body 422, thereby improving the stability of the rubber column body 422.

[0067] like Figure 5B As shown, the radial dimension D1 of the limiting hole 421 is smaller than the radial dimension D2 of the cavity 4221. The limiting hole 421 is used to fix the second connector 44, therefore the radial dimension D1 of the limiting hole 421 must match the radial dimension of the second connector 44. In addition, the smaller radial dimension D1 can ensure that the rubber column body 422 has a larger upper surface area, thereby improving the stability of the rubber column body 422.

[0068] The cavity 4221 is used for shock absorption, so the larger radial dimension D2 makes the rubber column body 422 more prone to deformation, thus giving the rubber column body 422 a better shock absorption effect.

[0069] When multiple grooves 4223 are formed on the sidewall 4222, multiple strip-shaped connecting segments are formed in the sidewall 4222, that is, there are strip-shaped connecting segments between the multiple grooves 4223.

[0070] Under conditions of low vibration, the connecting section can flexibly absorb vibration through small deformation. Under conditions of high vibration, the connecting section can expand and deform towards the groove 4223, providing deformation space for effective vibration absorption. In addition, multiple grooves 4223 are evenly distributed around the cavity 4221, allowing the rubber column body 422 to be uniformly stressed in all directions. The vibration absorption effect of the rubber column 42 can achieve uniformity in all directions, preventing the rubber column body 422 from tilting under external forces.

[0071] In an embodiment of this utility model, the radial dimension of the rubber column body 422 gradually decreases from both ends to the middle. The rubber column body 422 has a drum-shaped structure, with larger radial dimensions at both ends and narrower radial dimensions in the middle. For example, the radial dimension D4 of the rubber column body 422 is greater than the radial dimension D3 of the rubber column body 422.

[0072] During the stress process of the rubber column body 422, elastic deformation preferentially occurs in the central region of the rubber column body 422. Compared with a cylindrical structure of equal diameter, the rubber column body 422 can obtain a larger compressive deformation margin, and the two ends of the rubber column body 422 can deform towards the concave part of the central region. In addition, the rubber column body 422 of this structure can adapt to small swaying in multiple directions, improving the cushioning and impact resistance performance.

[0073] In the embodiments of this utility model, the hardness range of the rubber column 42 is Shore hardness 30 to Shore hardness 60.

[0074] The hardness of the rubber post 42 is adjustable. For example, the second connector 44 is detachable, allowing replacement with rubber posts 42 of different hardness. The hardness of the rubber post 42 can be adjusted for different applications. For example, for smooth road conditions, the hardness of the rubber post 42 can be set to Shore hardness 30°. For complex road conditions, the hardness of the rubber post 42 can be set to Shore hardness 60°.

[0075] Figure 6 A schematic diagram of the structure of an electronic device according to an embodiment of the present invention is shown.

[0076] like Figure 6 As shown, the electronic device 200 includes a device body 5 and a lidar device 100.

[0077] The outer casing of the device body 5 has a through hole 51, and the lidar 2 of the lidar device 100 is installed on the outside of the casing through the through hole 51.

[0078] In the embodiments of this utility model, the working process and structure of the lidar device 100 can be as described above. For the sake of brevity, similar parts will not be repeated.

[0079] In this embodiment of the invention, the outer shell of the device body 5 is further provided with a plurality of heat dissipation holes 52, which are arranged around the through hole 51. The heat dissipation holes 52 are used to dissipate heat for the lidar 2, thereby reducing the operating temperature of the lidar 2.

[0080] In embodiments of this invention, the electronic device 200 can be a robot, such as a service robot, delivery robot, cleaning robot, or patrol robot. The lidar device 100 enables the robot to perform environmental detection.

[0081] Figure 7 A cross-sectional schematic diagram of an electronic device according to an embodiment of the present invention is shown.

[0082] like Figure 7 As shown, the lidar 2 of the lidar device 100 is mounted on the outside of the device body 5 through a through hole 51, so that the lidar 2 can detect the external environment of the electronic device 200. The mounting bracket 1, the fixing bracket 3, and the connecting component 4 of the lidar device 100 are located on the inside of the device body 5 to provide a stable working environment for the mounting bracket 1, the fixing bracket 3, and the connecting component 4.

[0083] Figure 8 A schematic diagram illustrating the working principle of a lidar according to an embodiment of the present invention is shown.

[0084] like Figure 8As shown, the lidar 2 is mounted on the mounting plane 111 of the mounting bracket 1, and the lidar 2 forms an angle θ with the horizontal plane. For example, the angle θ can be 10°.

[0085] In this configuration, the field of view of lidar 2 can be compatible with the front blind zone 6 and the top region 7 to cover a wider detection area and supplement the radar's blind zone.
