Description

Technical Field

[0001] This utility model relates to the field of radar technology, specifically to a lidar base, lidar, and electronic equipment. Background Technology

[0002] Currently, an increasing number of electronic devices are using lidar as a distance measurement sensor. To reduce the space occupied within these devices, miniaturization of lidar has become an inevitable trend. Lidar drivers on the market typically use a drive motor to provide power, utilizing an intermediate transmission structure to rotate a turntable and its ranging components, thus achieving the lidar's ranging function. However, lidar typically sets the output shaft of the drive motor parallel to the rotation axis of the turntable, resulting in a large lidar size and occupying a significant amount of installation space within the electronic device. Utility Model Content

[0003] In view of this, this utility model provides a base for a lidar, to solve the problem that current lidars, by arranging the output shaft of the drive motor parallel to the rotation shaft of the turntable, result in a large lidar size and occupy a significant amount of installation space for electronic equipment. Furthermore, this utility model provides a lidar device. Additionally, this utility model provides an electronic device.

[0004] In a first aspect, this utility model provides a base for a lidar, comprising:

[0005] Mounting housing;

[0006] A turntable mechanism is rotatably disposed within the mounting housing, and the turntable mechanism is used to mount a ranging component;

[0007] A motor is disposed inside the mounting housing. The output shaft of the motor is connected to the turntable mechanism for transmission, so that the output shaft can drive the turntable mechanism to rotate. The output shaft of the motor is perpendicular to the rotation axis of the turntable mechanism.

[0008] Beneficial effects: This utility model provides a base for a lidar, in which the turntable mechanism and the motor are both housed in the same mounting housing, and the output shaft of the motor is perpendicular to the rotation shaft of the turntable mechanism. This makes the overall structure of the motor horizontally positioned on one side of the turntable mechanism, which reduces the vertical space occupied by the motor in the lidar base, making the arrangement of the motor in the lidar base more compact and reasonable, thereby reducing the size of the lidar and reducing the installation space occupied by the lidar in its carrier electronic equipment.

[0009] In one alternative embodiment, the base of the lidar further includes a transmission mechanism that is tractively connected between the turntable mechanism and the output shaft of the motor.

[0010] Beneficial effects: By setting a transmission mechanism between the turntable mechanism and the output shaft of the motor, the output shaft of the motor is perpendicular to the rotation shaft of the turntable mechanism, so as to realize the transmission of rotational power from the output shaft of the motor to the turntable mechanism, thereby enabling the motor to drive the turntable mechanism to rotate.

[0011] In one optional embodiment, the transmission mechanism is configured as an annular belt structure;

[0012] The turntable mechanism includes a rotating disk, and the outer periphery of the rotating disk is provided with a first annular groove;

[0013] The motor has a drive wheel on its output shaft, and the drive wheel has a second annular groove on its outer periphery;

[0014] The annular strip structure is wound and tensioned between the first annular groove and the second annular groove.

[0015] Beneficial effects: By setting the transmission mechanism as an annular belt structure, with the drive wheel wrapped around and tensioned on the output shaft of the motor and the outer circumference of the annular belt structure, the output shaft of the motor is perpendicular to the rotation axis of the turntable mechanism, thus realizing the transmission of rotational power from the output shaft of the motor to the turntable mechanism. The structure is simple and the power transmission is efficient.

[0016] In one alternative embodiment, the annular belt structure is configured as a belt.

[0017] Beneficial effects: The annular belt structure is designed as a belt, which facilitates installation between the first annular groove of the rotating disk and the second annular groove of the drive wheel by utilizing its elastic deformation. The installation is convenient and the force transmission is stable and efficient.

[0018] In one optional embodiment, the mounting housing is provided with a guide post, which is located between the turntable mechanism and the motor, and the outer side of the annular strip structure abuts against the guide post.

[0019] Beneficial effects: A guide post is provided between the rotating disk mechanism and the motor in the mounting housing, so that the outer side of the annular strip structure abuts against the guide post, ensuring that the annular strip structure is fully tensioned between the first annular groove of the turntable and the second annular groove of the drive wheel, thereby ensuring that the motor smoothly transmits the rotation of the turntable mechanism.

[0020] In one alternative embodiment, the guide post is integrally formed into the mounting housing; or, the guide post is embedded in the mounting housing.

[0021] Beneficial effects: The guide post is integrally molded into the mounting shell, which improves the overall integrity of the lidar base, and the guide post is embedded in the mounting shell, which reduces manufacturing costs.

[0022] In one optional embodiment, the turntable mechanism further includes a bearing, the inner ring of which is fixedly disposed on the mounting housing, and the outer ring of which is fixedly disposed on the rotating disk;

[0023] The base of the lidar also includes a toothed ring fixedly disposed on the mounting shell, and a retaining ring fixedly disposed on the rotating disk;

[0024] The toothed ring abuts against the upper end face of the bearing to restrict the axial upward movement of the bearing;

[0025] The retaining ring abuts against the lower end face of the bearing to restrict the axial downward movement of the bearing.

[0026] Beneficial effects: The turntable mechanism is rotatably connected to the mounting housing via bearings; the toothed ring and retaining ring fixedly installed on the mounting housing limit the bearings to prevent axial movement, thus ensuring the stability of the turntable mechanism's rotation.

[0027] In one optional embodiment, the base of the lidar further includes an internal PCB, which is fixedly disposed on the turntable mechanism and used for electrical connection to the ranging component.

[0028] Beneficial effects: By electrically connecting the ranging component to the internal PCB of the turntable mechanism, the ranging component on the turntable mechanism can rotate, thereby scanning the surrounding environment in 360° and realizing the ranging function of the lidar.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0061] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0062] A lidar is provided in related technologies, such as Figure 9 As shown, the output shaft of the drive motor d1 and the rotation shaft of the turntable d2 are arranged in parallel. This makes the drive motor d1 vertically positioned. Since the length of the drive motor d1 is usually greater than the thickness of the main structure of the lidar, this vertical arrangement results in a large lidar size, occupying significant installation space for electronic equipment. To address this issue, a lidar base, lidar, and electronic equipment are provided to solve the problem of current lidars that use parallel alignment between the drive motor's output shaft and the turntable's rotation shaft, leading to a large lidar size and significant space requirements for electronic equipment.

[0063] The following is combined Figures 1-8 The following describes embodiments of the present invention.

[0064] According to an embodiment of the present invention, in one aspect, a base for a lidar is provided, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes: mounting housing 1, turntable mechanism 2 and motor 3.

[0065] The turntable mechanism 2 is rotatably mounted inside the mounting housing 1, and the range measuring component is mounted on the turntable mechanism 2; the motor 3 is mounted inside the mounting housing 1, and the output shaft of the motor 3 is connected to the turntable mechanism 2 so that the output shaft can drive the turntable mechanism 2 to rotate, and the output shaft of the motor 3 is perpendicular to the rotation axis of the turntable mechanism 2.

[0066] In the above embodiment, the turntable mechanism 2 and the motor 3 are both housed in the same mounting housing 1, and the output shaft of the motor 3 is perpendicular to the rotation shaft of the turntable mechanism 2. This makes the overall structure of the motor 3 horizontally positioned on one side of the turntable mechanism 2. This reduces the vertical space occupied by the motor 3 on the base of the lidar, making the arrangement of the motor 3 on the base of the lidar more compact and reasonable, thereby reducing the size of the lidar and reducing the installation space occupied by the lidar on its carrier electronic equipment.

[0067] Specifically, in the lidar, a motor 3 drives a turntable mechanism 2 to rotate, causing the ranging component mounted on the turntable mechanism 2 to rotate, thereby performing a 360° omnidirectional scan of the surrounding environment and realizing the lidar's ranging function. During this operation, the ranging component is driven by the motor 3 through the turntable mechanism 2, achieving the rotation of the ranging component. In this embodiment, the overall structure of the motor 3 is arranged horizontally on one side of the turntable mechanism 2, so that the motor 3 only occupies the vertical space of the mounting shell 1 in its width direction. This makes the vertical space occupied by the motor 3 comparable to the thickness of the turntable mechanism 2, resulting in a more compact arrangement of the motor 3 on the lidar base. The arrangement of the motor 3 does not protrude relative to one side of the turntable mechanism 2, making the internal space layout of the lidar base more reasonable.

[0068] Furthermore, this embodiment does not limit the specific implementation of the transmission connection between the output shaft of the motor 3 and the turntable mechanism 2. That is, the transmission connection between the output shaft of the motor 3 and the turntable mechanism 2 can satisfy the rotation action of the turntable mechanism 2 and the perpendicular arrangement of the output shaft of the motor 3 and the rotation axis of the turntable mechanism 2.

[0069] In one implementation, the output shaft of the motor 3 is in direct contact with the turntable mechanism 2 to form a transmission connection.

[0070] In another implementation, the output shaft of the motor 3 and the turntable mechanism 2 are connected by an intermediate structure to form a transmission connection.

[0071] In some embodiments, such as Figure 2 , Figure 3 As shown, the base of the lidar also includes a transmission mechanism, which is connected between the output shaft of the turntable mechanism 2 and the motor 3.

[0072] In the above embodiment, a transmission mechanism is provided between the output shaft of the turntable mechanism 2 and the output shaft of the motor 3, so that while the output shaft of the motor 3 is perpendicular to the rotation shaft of the turntable mechanism 2, the output shaft of the motor 3 can transmit rotational power to the turntable mechanism 2, thereby enabling the motor 3 to drive the turntable mechanism 2 to rotate.

[0073] Specifically, the transmission mechanism is used as a transmission component on the existing structure of the output shaft of the motor 3 and the turntable mechanism 2 to transmit power; or, the transmission mechanism is used as an intermediate structure to transmit power between the output shaft of the motor 3 and the turntable mechanism 2.

[0074] Furthermore, this embodiment does not limit the specific structural form of the transmission mechanism between the output shaft of the motor 3 and the turntable mechanism 2.

[0075] One implementation method involves direct contact between the output shaft of the motor 3 and the turntable mechanism 2 to form a transmission connection. Part of the output shaft of the motor 3 is configured as a worm gear structure, and the outer periphery of the turntable mechanism 2 is configured as a worm wheel structure that cooperates with the aforementioned worm. Through the cooperation of the worm wheel and worm gear, while the output shaft of the motor 3 and the rotation axis of the turntable mechanism 2 are perpendicular, the output shaft of the motor 3 is used to transmit rotational power to the turntable mechanism 2.

[0076] As another implementation method, the output shaft of the motor 3 is directly connected to the turntable mechanism 2 to form a transmission connection. A first helical gear is provided on the output shaft of the motor 3, and the outer periphery of the turntable mechanism 2 is configured as a second helical gear structure that cooperates with the first helical gear. Through the cooperation and transmission of the helical gear set, while the output shaft of the motor 3 and the rotation axis of the turntable mechanism 2 are perpendicular, the output shaft of the motor 3 is used to transmit rotational power to the turntable mechanism 2.

[0077] As another implementation method, this method involves connecting the output shaft of the motor 3 and the turntable mechanism 2 through an intermediate structure to form a transmission connection. A circumferentially closed annular force transmission structure is provided between the output shaft of the motor 3 and the outer periphery of the turntable mechanism 2. Through the force transmission action of the annular force transmission belt, the output shaft of the motor 3 is perpendicular to the rotation axis of the turntable mechanism 2, thereby realizing the transmission of rotational power from the output shaft of the motor 3 to the turntable mechanism 2.

[0078] In some embodiments, such as Figure 2 , Figure 3 As shown, the transmission mechanism is configured as an annular belt structure 4; the turntable mechanism 2 includes a rotating disk 201, and the outer periphery of the rotating disk 201 is provided with a first annular groove 2011; the output shaft of the motor 3 is provided with a drive wheel 301, and the outer periphery of the drive wheel 301 is provided with a second annular groove 3011; the annular belt structure 4 is wound around and tensioned between the first annular groove 2011 and the second annular groove 3011.

[0079] In the above embodiment, the transmission mechanism is set as an annular belt structure 4, which is wound around and tensioned between the drive wheel 301 on the output shaft of the motor 3 and the outer periphery of the annular belt structure 4. While the output shaft of the motor 3 is set perpendicular to the rotation axis of the turntable mechanism 2, the output axis of the motor 3 is used to transmit rotational power to the turntable mechanism 2. The structure is simple and the power transmission is efficient.

[0080] Specifically, the turntable mechanism 2 is provided with a rotating disk 201 as the main force transmission structure, and a drive wheel 301 is provided on the output shaft of the motor 3 as the main force transmission structure. The annular belt structure 4 is respectively wound around the first annular groove 2011 of the rotating disk 201 and the second annular groove 3011 of the drive wheel 301 and is fully tensioned, thereby transmitting the rotational force output by the output shaft of the motor 3 to the rotating disk 201, so that the rotating disk 201 rotates.

[0081] Furthermore, in this embodiment, the turntable mechanism 2 is arranged vertically, the first annular groove 2011 on the outer periphery of the rotating disk 201 is located in the horizontal direction, while the motor 3 is arranged horizontally, and the second annular groove 3011 on the outer periphery of the drive wheel 301 is located in the vertical direction; therefore, the side of the annular strip structure 4 that is tensioned on the rotating disk 201 forms a 90° twist relative to the side that is tensioned on the drive wheel 301, so that the motor 3 and the turntable mechanism 2 form a vertical cross transmission.

[0082] Furthermore, this embodiment does not limit the specific structural form of the annular strip structure 4.

[0083] In one implementation, the annular strip structure 4 is designed as a chain.

[0084] In another implementation, the annular belt structure 4 is configured as a belt.

[0085] In some embodiments, such as Figure 2 , Figure 3 As shown, in a preferred embodiment, the annular belt structure 4 is configured as a belt.

[0086] In the above embodiment, the annular belt structure 4 is set as a belt, which makes it easy to install between the first annular groove 2011 of the rotating disk 201 and the second annular groove 3011 of the drive wheel 301 by utilizing its elastic deformation. The installation is convenient and the force transmission is stable and efficient.

[0087] In some embodiments, such as Figure 4 As shown, the mounting housing 1 is provided with a guide post 5, which is located between the turntable mechanism 2 and the motor 3. The outer side of the annular strip structure 4 abuts against the guide post 5.

[0088] In the above embodiment, a guide post 5 is provided between the turntable mechanism 2 and the motor 3 in the mounting housing 1, so that the outer side of the annular strip structure 4 abuts against the guide post 5, ensuring that the annular strip structure 4 is fully tensioned between the first annular groove 2011 of the rotating disk 201 and the second annular groove 3011 of the drive wheel 301, thereby ensuring that the motor 3 smoothly transmits the rotation of the turntable mechanism 2.

[0089] Specifically, the guide post 5 is connected to the base plate of the mounting shell 1, located between the turntable mechanism 2 and the motor 3 and close to the front end of the motor 3. The outer side of the annular strip structure 4 abuts against the guide post 5 to avoid interference between the annular strip structure 4 and the outer shell at the front end of the motor 3.

[0090] Furthermore, the surface roughness of the guide post 5 material is lower than Ra0.1μm to ensure smooth sliding of the annular strip structure 4.

[0091] In some embodiments, such as Figure 4As shown, the guide post 5 is integrally formed into the mounting shell 1; or, the guide post 5 is embedded in the mounting shell 1.

[0092] In the above embodiments, the guide post 5 is integrally formed into the mounting shell 1 to improve the overall integrity of the lidar base, and the guide post 5 is embedded in the mounting shell 1 to reduce manufacturing costs.

[0093] Specifically, when the guide post 5 is integrally formed into the mounting shell 1, the mounting shell 1 and the guide post 5 are integrally injection molded using a self-lubricating material such as polyoxymethylene, so that the outer surface of the guide post 5 forms a smooth surface with a surface roughness lower than Ra0.1μm; when the guide post 5 is embedded in the mounting shell 1, a metal shaft is inlaid or riveted at the corresponding position on the mounting shell 1 as the guide post 5, and the metal shaft is made of a metal material with a low coefficient of friction such as aluminum or copper, so that the outer surface of the guide post 5 forms a smooth surface with a surface roughness lower than Ra0.1μm.

[0094] In some embodiments, such as Figure 2 As shown, the turntable mechanism 2 also includes a bearing 202, the inner ring of which is fixedly mounted on the mounting shell 1, and the outer ring of which is fixedly mounted on the rotating disk 201; the base of the lidar also includes a toothed ring 6 fixedly mounted on the mounting shell 1, and a retaining ring 7 fixedly mounted on the rotating disk 201; the toothed ring 6 abuts against the upper end face of the bearing 202 to restrict the axial upward movement of the bearing 202; the retaining ring 7 abuts against the lower end face of the bearing 202 to restrict the axial downward movement of the bearing 202.

[0095] In the above embodiment, the turntable mechanism 2 is rotatably connected to the mounting shell 1 by the bearing 202; the toothed ring 6 and the retaining ring 7 fixedly set on the mounting shell 1 limit the bearing 202 to prevent the bearing 202 from moving along the axis, so as to ensure the stability of the rotation of the turntable mechanism 2.

[0096] Specifically, the rotating disk 201 of the turntable mechanism 2 is rotatably connected to the mounting shell 1 via the bearing 202, thereby rotatably connecting the entire turntable mechanism 2 to the mounting shell 1; while limiting the bearing 202 and the entire turntable mechanism 2, the toothed ring 6, through its evenly distributed teeth or coding pattern on its circumference, cooperates with the corresponding sensor on the ranging component to accurately measure the angle of rotation, thereby accurately knowing the angular position of the laser emitting and receiving modules at different times, providing accurate angle information for subsequent cloud data processing and target positioning.

[0097] Furthermore, bearing 202 is configured as a ball bearing.

[0098] In some embodiments, such as Figure 1 , Figure 2 As shown, the base of the lidar also includes an internal PCB8, which is fixedly mounted on the turntable mechanism 2 and is used to electrically connect the ranging component.

[0099] In the above embodiment, the ranging component is electrically connected to the internal PCB8 fixedly installed on the turntable mechanism 2, so that the ranging component installed on the turntable mechanism 2 can rotate, thereby scanning the surrounding environment in all directions of 360° and realizing the ranging function of the lidar.

[0100] Specifically, the internal PCB8, i.e., the internal circuit board, is configured with corresponding ports and connectors between itself and the ranging component, thereby forming a stable electrical connection.

[0101] In some embodiments, such as Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the mounting housing 1 is divided into an upper cavity 101 and a lower cavity 102 by a middle partition plate, and a through hole 103 is provided on the middle partition plate; the turntable mechanism 2 and the motor 3 are located in the upper cavity 101, and the external PCB 9 is located in the lower cavity 102, and the lower cavity 102 is provided with a terminal interface 901 and an external power interface 902; the drive connector 302 of the motor 3 passes through the through hole 103 and is electrically connected to the terminal interface 901 on the external PCB 9, and the external power interface 902 is used to electrically connect to an external power source.

[0102] Specifically, the external PCB9 is the same as the internal circuit board; after the external power supply is electrically connected to the external power interface 902, the power is transmitted to the motor 3 through the electrical connection of the terminal interface 901 and the drive connector 302, so that the output shaft of the motor 3 drives the turntable mechanism 2 to rotate.
