Description

Technical Field

[0001] This application relates to the field of vibration isolation technology, and in particular to detection devices and terminals. Background Technology

[0002] With the development of information technology and computer vision, detection technology has advanced rapidly, bringing great convenience to people's lives and travel. Detection devices (such as lidar) are the "eyes" of equipment sensing the environment, playing a crucial role in this process, especially in the field of integrated driver assistance systems (ADAS), where they have achieved widespread application and can further contribute to the development of ADAS technology. Detection devices contain driving components (such as motors), which generate vibration and noise during operation. Since detection devices are usually directly mounted on vehicles, the vibration and noise generated during operation are transmitted to the vehicle, resulting in higher noise levels inside the vehicle and affecting the comfort of passengers. Utility Model Content

[0003] This application provides a detection device and terminal that can reduce the transmission of vibration between the detection device and the vehicle, thereby reducing vibration noise and the impact of vibration on the measurement of the detection device, and improving the comfort of the driver and passengers.

[0004] In a first aspect, this application provides a detection device, which includes a housing, a cavity, a positioning post, a mounting bracket, and a first vibration damping assembly.

[0005] The cavity is surrounded by the outer shell, and the positioning post, the mounting bracket and the first vibration damping component are all located inside the cavity;

[0006] The positioning post is fixedly connected to the outer shell and protrudes relative to the inner wall of the cavity;

[0007] The mounting bracket is connected to the positioning column via the first vibration damping component to be fixed relative to the outer shell, and the mounting bracket is used to connect to the vibration source.

[0008] Understandably, in related technologies, to isolate vibrations and noise between the detection device and the vehicle, vibration-damping brackets are typically added between the external detection device and the vehicle body to reduce the transmission of vibrations and noise. However, this method of blocking vibrations and noise places high demands on the manufacturing and assembly of the vibration-damping brackets, easily leading to increased costs and installation difficulties. Furthermore, because this method isolates vibrations externally to the detection device, the detection device may overlap with other components on the vehicle, making it difficult to completely isolate vibrations and affecting the installation accuracy of the detection device.

[0009] In view of this, the technical solution of this application involves setting a positioning post inside the outer shell and fixing the positioning post to the outer shell, and setting the positioning post to protrude relative to the inner wall of the cavity. On the one hand, the structural form of the positioning post protruding from the inner wall of the cavity can be used to provide a certain pre-position for the installation of the first vibration damping component, which not only serves as a visual reminder, but also provides a certain support performance for the first vibration damping component, with strong assemblability and low cost. On the other hand, the protruding positioning post ensures a certain distance between the mounting bracket and the outer shell, which can avoid the problem of rigid collision caused by the mounting bracket being too close to the outer shell and thus aggravating the vibration when the vibration source vibrates.

[0010] Furthermore, since the mounting bracket is connected to the vibration source, the area where the mounting bracket is located is the area with the strongest vibration in the detection device. By placing the first vibration damping component inside the outer shell of the detection device and connecting it to the connection between the mounting bracket and the positioning column, the vibration damping effect of the first vibration damping component can be utilized to block vibration and noise at the source of vibration. This suppresses vibration transmission along the vibration transmission path from the vibration source to the mounting bracket to the outer shell, reduces vibration and noise caused by the vibration of the vibration source, and improves the overall NVH (Noise, Vibration, Harshness) performance of the detection device. This internal vibration isolation scheme not only offers better compatibility with the vehicle and requires no special installation requirements, making installation more convenient, but also provides a single isolation path. This effectively prevents vibrations and noise from the vibration source from amplifying and spreading outwards through the outer shell, thus avoiding the problem of the isolation area being expanded and the vibration isolation performance deteriorating. It reduces the vibration area that needs to be isolated in the detection device, maximizes the optimization of vibration isolation efficiency, and aims to reduce or even eliminate vibration, thereby reducing noise. This effectively improves the comfort of passengers and reduces the impact of vibration on the measurement of the detection device.

[0011] Furthermore, due to the internal vibration isolation of the detection device, even if there is a rigid connection between the detection device and its carrier (i.e., the exterior of the detection device), the vibration can be reduced at the source due to the internal vibration isolation scheme. This significantly reduces the vibration and noise transmitted from the detection device to the carrier, optimizing the riding experience for passengers. A rigid connection refers to fixing two mechanical components together using a rigid connection (such as bolts, welding, riveting, etc.) to maintain relative stability during movement or under stress.

[0012] In one possible implementation, the first vibration damping component includes a first vibration isolation sleeve and a first locking structure. The first vibration isolation sleeve passes through the mounting bracket and is sleeved on the outside of the positioning post. The first locking structure is inserted into the first vibration isolation sleeve and abuts against the first locking structure. The first locking structure is also connected to the positioning post.

[0013] It is understandable that by inserting the first locking structure into the first vibration isolation sleeve and connecting the first locking structure with the positioning post nested in the first vibration isolation sleeve, the supporting performance of the positioning post can be utilized to provide good assembly performance for the first locking structure, ensuring the assembly accuracy and fixation stability of the first locking structure, and thus achieving better reliability.

[0014] In one possible implementation, the first locking structure is detachably connected to the positioning post.

[0015] In this configuration, the first locking structure can be locked to the positioning post to achieve a fixed connection between the first damping component and the positioning post. The first locking structure can also be unlocked from the positioning post to allow the first damping component to be detached from it. By making the first locking structure detachably connected to the positioning post, the assembly process of the first damping component is simplified, facilitating its assembly and transportation. Furthermore, it allows for easy disassembly of the first damping component for repair or replacement of components should a malfunction occur, thus improving the overall assemblability of the first damping component.

[0016] In one possible implementation, the first locking structure is used to pre-press the first vibration isolation sleeve onto the outer shell before locking it with the positioning post.

[0017] Pre-compression refers to applying a certain pressure (or compression) to the first vibration isolation sleeve before its use, placing it in a pre-tightened state. Clamping direction refers to the direction of the clamping force acting on the first vibration isolation sleeve. The clamping force can be vertical, horizontal, oblique, or a combination of multiple directions. Pre-compression amount refers to the amount of compression applied to the first vibration isolation sleeve during installation or commissioning. This pre-compression ensures the first vibration isolation sleeve is under a certain stress state from the initial stage, thereby optimizing its vibration isolation performance.

[0018] Understandably, on the one hand, the first vibration isolation sleeve, without preloading, may undergo significant deformation during initial loading, even exceeding its elastic range, leading to irreversible damage. Preloading allows the first vibration isolation sleeve to reach a stable working state earlier, preventing damage due to excessive deformation in the early stages of use and improving its impact resistance. On the other hand, without preloading, the initial stiffness of the first vibration isolation sleeve may be high, resulting in a high vibration transmission rate. Preloading reduces the initial stiffness of the first vibration isolation sleeve, decreasing the transmission of initial vibrations.

[0019] In one possible implementation, the first vibration isolation sleeve is clamped between the first locking structure and the outer shell in the axial direction of the first vibration isolation sleeve;

[0020] In the radial direction of the first vibration isolation sleeve, the first vibration isolation sleeve is clamped between the positioning post and the mounting bracket.

[0021] It is understandable that by clamping the first vibration isolation sleeve in both the axial and radial directions, the first vibration isolation sleeve can be fixed in the assembly position by the cooperation of the first locking structure, the outer shell, the mounting bracket and the positioning post, ensuring the relative positional accuracy between the first vibration isolation sleeve and other surrounding components, ensuring assembly quality, and improving the connection strength and reliability between the first vibration isolation sleeve and other surrounding components.

[0022] In one possible implementation, the first vibration isolation sleeve has a preload of 10%-30% in the clamping direction between the first locking structure and the housing.

[0023] The first vibration isolation sleeve is a structural component with a certain degree of elasticity. Before being compressed, it is in a free state. After being compressed, it undergoes elastic deformation and compression, and it rebounds after the pressure is removed. The pre-compression amount of the first vibration isolation sleeve in the clamping direction between the first locking structure and the outer shell refers to the amount by which the first vibration isolation sleeve is pre-compressed in the clamping direction between the first locking structure and the outer shell (i.e., the axial direction of the first vibration isolation sleeve). Structurally, this can be expressed as a reduction in the height of the first vibration isolation sleeve after pre-compression compared to its free height before pre-compression.

[0024] Therefore, the 10%-30% preload of the first vibration isolation sleeve in the clamping direction between the first locking structure and the outer shell means that, if the free height of the first vibration isolation sleeve before preloading is H, then in the clamping direction between the first locking structure and the outer shell, the height of the first vibration isolation sleeve after preloading will be reduced by 0.1H to 0.3H (including the endpoint values ​​of 0.1H and 0.3H) relative to the free height H of the first vibration isolation sleeve. The specific value of H can be selected according to the actual application scenario and is not strictly limited. Those skilled in the art will know that due to the influence of processes, environment, etc., there may be slight deviations in the actual value range of 10%-30%.

[0025] It is understandable that by setting the preload of the first vibration isolation sleeve in the clamping direction of the first locking structure and the housing within the aforementioned range, the first vibration isolation sleeve can have an appropriate preload to better perform its vibration isolation function during operation, increase the rigidity of the first damping component, reduce vibration transmission, and improve the stability and reliability of the first damping component.

[0026] In one possible implementation, the first locking structure includes a first locking member and a first washer;

[0027] The first locking member is inserted into the positioning post and connected to the positioning post;

[0028] The first gasket is sleeved on the outside of the first locking member and abuts against the first vibration isolation sleeve, with at least a portion of the first gasket located inside the first vibration isolation sleeve.

[0029] It is understandable that by inserting the first locking member into the first vibration isolation sleeve and connecting the first locking member with the positioning post nested in the first vibration isolation sleeve, the supporting performance of the positioning post can be utilized to provide good assembly performance for the first locking member, ensuring the assembly accuracy and fixation stability of the first locking member, and thus achieving better reliability.

[0030] Furthermore, a first shim is provided between the first locking member and the first vibration isolation sleeve. On one hand, the first shim increases the friction between the first locking member and the first vibration isolation sleeve, thereby preventing the first locking member from loosening due to vibration or impact during use. On the other hand, the first shim acts as a buffer layer to protect the surface of the first vibration isolation sleeve from damage, preventing scratches or wear caused by the first locking member during connection with the positioning post. It can also be used to adjust the gap between the first connecting member and the positioning post, ensuring a tight and consistent connection.

[0031] In one possible implementation, the first locking member includes a first state and a second state;

[0032] When the first locking member is in the first state, there is a gap between the first gasket and the end of the positioning post away from the housing, and the first vibration isolation sleeve is pressed against the housing by the first gasket. In this state, the first vibration isolation sleeve can be in a compressed state. Alternatively, the first vibration isolation sleeve can be in a pre-compressed state. For example, when the first vibration isolation sleeve is in the compressed state, the gap between the first gasket and the second connecting end of the positioning post can be caused by the detection device loosening due to vibration. When the first vibration isolation sleeve is in the pre-compressed state, the first gasket can act as the object that applies pre-pressure to the first vibration isolation sleeve in the first locking structure, so that the first vibration isolation sleeve can maintain a certain tension, thereby improving the overall impact resistance of the first vibration isolation sleeve.

[0033] When the first locking member is in the second state, the first washer abuts against the end of the positioning post away from the outer shell, and the first vibration isolation sleeve is pressed against the outer shell by the first washer. In this state, the first vibration isolation sleeve can be in a compressed state. In the axial direction of the first vibration isolation sleeve, the first vibration isolation sleeve is clamped between the first washer and the outer shell, thereby fixing the first vibration isolation sleeve and the mounting bracket relative to the outer shell.

[0034] In one possible implementation, a conductive path is formed at the contact point between the first vibration isolation sleeve and the mounting bracket.

[0035] Understandably, since the first vibration isolation sleeve is in contact with both the mounting bracket and the outer casing, a conductive path is formed at the contact point between the first vibration isolation sleeve and the mounting bracket. This creates a current path of "mounting bracket - first vibration isolation sleeve - outer casing," allowing electrical conduction between the mounting bracket and the outer casing through the first vibration isolation sleeve, thereby grounding the mounting bracket. In other words, the first vibration isolation sleeve can function as both vibration isolation and grounding, which helps ensure the normal operation of the detection device and improves its stability.

[0036] In one possible implementation, the detection device further includes a conductive structure connected to at least one of the mounting bracket and the first vibration isolation sleeve, the conductive structure being located at the connection between the mounting bracket and the first vibration isolation sleeve.

[0037] This ensures that a current path can be formed between the first vibration isolation sleeve and the mounting bracket, so as to realize the grounding function of the first vibration isolation sleeve.

[0038] In one possible implementation, the mounting bracket is provided with a first mounting hole, and the outer surface of the first vibration isolation sleeve is recessed with a first mounting groove, and the first vibration isolation sleeve is engaged with the first mounting hole through the first mounting groove.

[0039] It is understandable that when the first vibration isolation sleeve is engaged with the mounting bracket, the first vibration isolation sleeve can be inserted into the first mounting hole of the mounting bracket, and part of the mounting bracket can be located in the first mounting groove of the first vibration isolation sleeve, so that the first vibration isolation sleeve and the mounting bracket can be embedded into each other, thereby making the relative fixed relationship between the first vibration isolation sleeve and the mounting bracket more stable and reliable, which is conducive to enhancing the connection strength between the first vibration isolation sleeve and the mounting bracket, and is convenient to disassemble and has strong assembly capability.

[0040] In one possible implementation, the mounting bracket has a first notch that extends through the outer edge of the mounting bracket and communicates with the first mounting hole, and the first notch can expose a portion of the first mounting groove.

[0041] Understandably, by providing a first notch on the mounting bracket, extending through the outer edge of the mounting bracket and communicating with the first mounting hole, two advantages are achieved. First, during the assembly of the first vibration isolation sleeve and the mounting bracket, it is convenient to insert the first vibration isolation sleeve into the first mounting hole from the position of the first notch, which improves the assembly efficiency and ease of assembly. Second, since the mounting bracket only contacts a portion of the inner surface of the first mounting groove, there will be a certain gap between the mounting bracket and the remaining portion of the inner surface of the first mounting groove, except for the contact point between the mounting bracket and the inner surface of the first mounting groove. This allows the force exerted by the mounting bracket on the first vibration isolation sleeve during assembly with the mounting bracket to be dispersed from the contact point between the mounting bracket and the inner surface of the first mounting groove (i.e., the location of the first notch) into the gap between the inner surfaces of the mounting bracket and the first mounting groove (i.e., the location of the first notch) when the compression is too large due to manufacturing or assembly tolerances. This helps to avoid stress concentration at the contact point between the mounting bracket and the inner surface of the first mounting groove, which could lead to cracking of the first vibration isolation sleeve, and increases the connection stability and reliability between the mounting bracket and the first vibration isolation sleeve.

[0042] In one possible implementation, the first mounting hole includes a first sub-hole and a second sub-hole that are connected to each other. The central axis of the first sub-hole is coaxially arranged with the central axis of the positioning post. The diameter of the second sub-hole is larger than the diameter of the first sub-hole. Both the diameter of the first sub-hole and the diameter of the second sub-hole are larger than the diameter of the connection between the second sub-hole and the first sub-hole. The first vibration isolation sleeve passes through the first mounting hole and can switch between the first sub-hole and the second sub-hole.

[0043] Understandably, since the first mounting hole has two interconnected sub-holes with different diameters, it can have a gourd-like structure. This gourd-like structure allows the first vibration isolation sleeve to have a certain adjustment space within the first mounting hole, thus dispersing the stress in the first mounting hole, avoiding the occurrence of stress concentration points, thereby improving the structural strength and service life of the first mounting hole, and facilitating the fixing and positioning of the first vibration isolation sleeve.

[0044] In one possible implementation, the first vibration isolation sleeve passes through the first sub-hole to be fixed relative to the mounting bracket, and the first vibration isolation sleeve is also sleeved on the outside of the positioning post.

[0045] Understandably, when assembling the first vibration isolation sleeve onto the mounting bracket, the first vibration isolation sleeve can first be inserted through the second sub-hole with a relatively larger diameter, and then gradually moved from the second sub-hole to the first sub-hole with a relatively smaller diameter, finally achieving relative fixation with the mounting bracket at the first sub-hole. When removing the first vibration isolation sleeve from the mounting bracket, the first vibration isolation sleeve can first be unlocked from the mounting bracket at the first sub-hole, and then gradually moved from the first sub-hole with a relatively smaller diameter to the second sub-hole with a relatively larger diameter, finally detaching from the mounting bracket at the second sub-hole. Switching between the first and second sub-holes facilitates the installation and removal of the first vibration isolation sleeve.

[0046] In one possible implementation, the positioning post is integrally formed with the outer shell.

[0047] With this setup, the detection device has fewer parts, which helps simplify the manufacturing process and improve the production and assembly efficiency of the detection device.

[0048] In one possible implementation, the detection device further includes a driveable component and a motor, both of which are located within the cavity. The motor is connected to the mounting bracket and is driveably connected to the driveable component, and is used to drive the driveable component to move.

[0049] The motor can be the vibration source described above. A transmission connection refers to a connection that connects the motor, which serves as a power source, to the driven component, which acts as an actuator, to achieve effective power transmission and motion conversion. Transmission connections can include fixed connections and kinematic pair connections (such as lower-pair connections and higher-pair connections). For example, the driven component can be a reflector, a rotating mirror, etc.

[0050] In one possible implementation, the detection device further includes a light emitter, a light receiver, and a scanner, all located within the cavity. The light emitter emits a detection beam toward a target object, the light receiver receives the echo beam generated after the detection beam is reflected by the target object, and the scanner includes the mounting bracket and the vibration source. The scanner transmits the detection beam to the outside of the detection device and returns the echo beam to the inside of the detection device.

[0051] In one possible implementation, the detection device is a lidar.

[0052] Secondly, this application also provides a terminal, which includes the detection device described above.

[0053] In one possible implementation, the terminal is a vehicle, drone, or robot.

[0054] In one possible implementation, the terminal further includes an adapter bracket and a carrier, with the detection device connected to the carrier via the adapter bracket;

[0055] The terminal further includes a second vibration damping component, which is connected between the adapter bracket and the carrier, and / or the second vibration damping component is connected between the housing and the adapter bracket.

[0056] Understandably, by adding a second vibration damping component to the outside of the detection device, which already has a first vibration damping component inside the detection device, the vibration inside the detection device can be attenuated layer by layer through the vibration isolation effect of the second vibration damping component, so as to further reduce or even eliminate the vibration, thereby reducing noise and effectively improving the comfort of the driver and passengers.

[0057] In one possible implementation, the second vibration damping component includes a second vibration isolation sleeve and a second locking structure. The second vibration isolation sleeve passes through the adapter bracket, and the second locking structure passes through the housing and the second vibration isolation sleeve, thereby fixing the housing to the adapter bracket.

[0058] It is understandable that the deformation of the second vibration isolation sleeve in the second vibration damping component can convert the relative vibration or impact energy between the detection device and the adapter bracket in the axial and radial directions into the deformation energy of the second vibration isolation sleeve, thereby playing a role in vibration isolation and buffering, so as to reduce vibration noise and reduce the problem of reduced reliability of the detection device caused by vibration.

[0059] In one possible implementation, the second vibration isolation sleeve includes a first end and a second end, the first end having a serrated structure, and / or the second end having a serrated structure.

[0060] Understandably, by setting a serrated structure at the first and / or second end of the second vibration isolation sleeve, the stiffness of the second vibration isolation sleeve can be effectively reduced, the vibration frequency can be lowered, and vibration transmission can be mitigated. In addition, the serrated structure can also reduce the contact area between the second vibration isolation sleeve and the side to be connected, thereby improving the vibration isolation rate.

[0082] Multiple: refers to two or more.

[0083] Connection: should be interpreted broadly. For example, the connection between A and B can be a direct connection between A and B, or an indirect connection between A and B through an intermediary.

[0085] Relative arrangement: This refers to orientation relative to each other, but it does not necessarily mean that the orientations of the two components must be completely opposite. For example, if the first component and the second component are arranged relative to each other, it means that the first component is roughly facing the first component. However, in some cases, the orientation of the components may have a certain tilt angle.

[0086] The terms "first," "second," "third," and other various designations are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

Unless otherwise specified or in accordance with logical conflicts, the terminology and / or descriptions between different embodiments of this application are consistent and can be mutually referenced. Technical features in different embodiments can be combined to form new embodiments based on their inherent logical relationships.

[0089] The specific embodiments of this application will now be clearly described in conjunction with the accompanying drawings.

[0090] Embodiments of this application provide a detection device and a terminal.

[0091] To facilitate understanding, the application scenarios of the detection device provided in this application embodiment will be briefly described first. The working principle of the detection device is to detect the corresponding detection area by emitting light signals and receiving the returned light signals. The detection device can be applied in fields such as integrated assisted driving, intelligent transportation, intelligent manufacturing, environmental monitoring, surveying and mapping, and unmanned aerial vehicles.

[0092] Specifically, the detection device can be installed on a vehicle and assist the vehicle in achieving one or more of the following functions: target detection, distance measurement, speed measurement, high-precision positioning, obstacle recognition, and imaging recognition. The detection device can be, but is not limited to, vehicle-mounted detection devices such as LiDAR (light detection and ranging), roadside detection devices such as intersection radar, or other detection devices. The vehicle can be, but is not limited to, vehicles, drones, robots, railcars, bicycles, traffic lights, speed measuring devices, or base stations.

[0093] In one possible implementation, the detection device can be a lidar. Lidar has the advantages of high resolution, good detection performance, and strong concealment, playing an important role in the process of equipment sensing the environment. It has been widely used, especially in the field of integrated driver assistance systems, and can help further develop integrated driver assistance technology.

[0094] Taking the application of lidar in vehicles as an onboard radar as an example, lidar can achieve at least one of the following functions or a combination of several of them:

[0095] 1. Scan the environment around the vehicle in real time or periodically to generate high-precision 3D point cloud data to determine the vehicle's position and / or to perform path planning and decision-making.

[0096] Second: To enable the identification and avoidance of physical objects such as roads, lane lines, obstacles, pedestrians and other vehicles during vehicle operation.

[0097] Three: Assist vehicles in maintaining their lane.

[0098] 4. Assist vehicle emergency braking.

[0099] 5. Assisting with parking when the car is parked.

[0100] The working principle of LiDAR (LiDAR) can be summarized as follows: LiDAR emits a detection beam in a specific direction. If a target object exists within the detection area of ​​the LiDAR, the target object can reflect the received detection beam back to the LiDAR (the reflected beam can be called the echo beam). The LiDAR then determines the correlation information of the target object based on the echo beam. In other words, LiDAR can sense the vehicle's surrounding environment and obtain the correlation information of target objects in the surrounding environment. This correlation information of target objects can be used to control the vehicle or assist the driver in driving.

[0101] For example, the vehicle's latitude and longitude can be used to determine its location. Alternatively, the vehicle's speed and orientation can be used to determine its direction of travel and destination. Or, the distance between the vehicle and surrounding objects can be used to determine the number and density of obstacles around the vehicle. Furthermore, the functions of advanced driving assistance systems (ADAS) can be combined to achieve assisted driving or autonomous driving.

[0102] It should be noted that the application scenarios listed above are merely illustrative of one possible application scenario for LiDAR. The LiDAR provided in the embodiments of this application can also be applied to a variety of other possible scenarios, and is not limited to the scenarios exemplified above. For example, LiDAR can be installed on a drone as an airborne radar. Alternatively, LiDAR can be installed on a roadside unit (RSU) and used as a roadside LiDAR to achieve vehicle-to-infrastructure (V2I) communication. Or, LiDAR can also be installed on an automated guided vehicle (AGV).

[0103] The following description will use a vehicle-mounted detection device as an example to illustrate the structure of the detection device, but it should be understood that this is not the only explanation.

[0104] Understandably, as described in the background section, detection devices are typically mounted directly on vehicles. Since the detection device contains internal drive components, these components generate vibration and noise during operation. Based on the connection between the detection device and the vehicle, the vibration and noise generated by the detection device are transmitted to the passenger compartment through components such as the mounting bracket connecting the vehicle body and the detection device, the vehicle body beams supporting the detection device, and decorative covers that enclose the detection device and connect to the vehicle body panels. Excessive vibration can lead to significant vibration and noise inside the vehicle, affecting the comfort of passengers. Furthermore, since vehicles frequently experience bumps during operation, the detection device also vibrates with these bumps. This vibration can cause internal components of the detection device to move or be damaged, reducing its reliability.

[0105] In view of this, embodiments of this application provide a detection device and terminal that can reduce the transmission of vibration between the detection device and the carrier, thereby reducing vibration noise and the impact of vibration on the measurement of the detection device.

Figure 2 and Figure 3For ease of illustration, only a portion of the outer casing 10 of the detection device 100 is shown in the image.

[0107] The detection device 100 may include a housing 10, a cavity W, a mounting bracket 20, a positioning post 30, and a first vibration damping component 40. The cavity W may be surrounded by the housing 10. The positioning post 30, the mounting bracket 20, and the first vibration damping component 40 may all be located within the cavity W. The positioning post 30 may be fixedly connected to the housing 10 and protrude relative to the inner wall of the cavity W. The mounting bracket 20 may be located above the positioning post 30. The mounting bracket 20 may be used to connect to a vibration source 50 to provide a mounting position for the vibration source 50 and support the vibration source 50. The mounting bracket 20 may be connected to the positioning post 30 via the first vibration damping component 40 to be fixed relative to the housing 10, thus achieving a fixed connection between the mounting bracket 20 and the housing 10.

[0108] in, Figures 1-3 The purpose is merely to schematically illustrate the connection relationship between the outer casing 10, the cavity W, the mounting bracket 20, the positioning post 30, and the first vibration damping component 40, and is not to specifically limit the connection position, specific structure, or quantity of each component. Furthermore, the structure illustrated in the embodiments of this application does not constitute a specific limitation on the detection device 100. In other embodiments of this application, the detection device 100 may include components such as... Figures 1-3 This may involve more or fewer components, or combining certain components, or splitting certain components, or different component arrangements. Figures 1-3 The components shown can be implemented in hardware, software, or a combination of both.

[0109] Understandably, in related technologies, to isolate vibrations and noise between the detection device and the vehicle, vibration-damping brackets are typically added between the external detection device and the vehicle body to reduce the transmission of vibrations and noise. However, this method of blocking vibrations and noise places high demands on the manufacturing and assembly of the vibration-damping brackets, easily leading to increased costs and installation difficulties. Furthermore, because this method isolates vibrations externally to the detection device, the detection device may overlap with other components on the vehicle, making it difficult to completely isolate vibrations and affecting the installation accuracy of the detection device.

[0110] Based on this, in the embodiments of this application, a positioning post 30 is provided inside the outer shell 10 and fixedly connected to the outer shell 10, and the positioning post 30 protrudes relative to the inner wall of the cavity W. On the one hand, the structure of the positioning post 30 protruding from the inner wall of the cavity W can be used to provide a certain pre-position for the installation of the first vibration damping component 40, which not only serves as a visual reminder but also provides a certain support for the first vibration damping component 40, with strong assemblability and low cost. On the other hand, the protruding positioning post 30 ensures a certain distance between the mounting bracket 20 and the outer shell 10, which can prevent the problem of rigid collision caused by the mounting bracket 20 being too close to the outer shell 10, thus avoiding the aggravation of vibration, when the vibration source 50 vibrates.

[0111] Furthermore, since the mounting bracket 20 is connected to the vibration source 50, the area where the mounting bracket 20 is located is a region of strong vibration within the detection device 100. By placing the first vibration component inside the housing 10 of the detection device 100 and connecting it to the connection between the mounting bracket 20 and the positioning post 30, the vibration damping effect of the first vibration damping component 40 can be utilized to block vibration and noise at the source of vibration. This suppresses vibration transmission along the vibration transmission path from the vibration source 50 to the mounting bracket 20 to the housing 10, reducing vibration and noise caused by the vibration of the vibration source 50 and improving the overall NVH (Noise, Vibration, Harshness) performance of the detection device 100. This internal vibration isolation scheme not only has better compatibility with the whole vehicle and no special requirements for vehicle installation, making installation more convenient, but also has a single blocking path, which can effectively prevent the vibration and noise emitted by the vibration source 50 from being amplified and diffused outward through the outer shell 10, thus avoiding the problem of the vibration isolation area being expanded and the vibration isolation performance being reduced. It reduces the vibration area that needs to be blocked in the detection device 100, optimizes the vibration isolation efficiency to the maximum extent, so as to reduce or even eliminate vibration, thereby reducing noise, effectively improving the comfort of passengers, and reducing the impact of vibration on the measurement of the detection device 100.

[0112] Furthermore, because vibration isolation is implemented inside the detection device 100, even if there is a rigid connection at the junction of the detection device 100 and its carrier 230 (i.e., the exterior of the detection device 100), the vibration can be reduced at the source due to the implementation of the internal vibration isolation scheme. This significantly reduces the vibration and noise transmitted from the detection device 100 to the carrier 230, optimizing the riding experience for passengers. A rigid connection refers to fixing two mechanical components together using a rigid connection (such as bolts, welding, riveting, etc.) to maintain relative stability during movement or under stress.

[0113] The relative positions of the components in the detection device 100 have been briefly described above. The following section will describe in detail the structure of each component in the detection device 100 and the connection relationship between them, with reference to the accompanying drawings.

[0114] Please refer to the following: Figures 1-3 The outer casing 10 can be the external component of the detection device 100, and also the mounting base for the remaining structures in the detection device 100. The outer casing 10 can enclose the cavity W forming the detection device 100. The outer casing 10 can be a one-piece structure, or it can be a separate structure.

[0115] When the housing 10 is a one-piece structure, the housing 10 can be an independent structural component, and the cavity W is an independent cavity W. In this configuration, the housing 10 has fewer parts, which simplifies the manufacturing process of the housing 10 and improves the production and assembly efficiency of the detection device 100. For example, the housing 10 can be formed into a one-piece structure by means such as integral molding.

[0116] When the outer shell 10 has a split structure, it can be formed by splicing multiple sub-shells, such as by welding, bonding, or snap-fitting. The cavity W is also formed by the joint enclosure of multiple sub-shells; that is, the cavity W can be formed by splicing multiple sub-cavities W surrounded by multiple sub-shells. In this configuration, the outer shell 10 can be disassembled into multiple shells, which can then be assembled layer by layer. This avoids the problems of excessive length, reduced strength, and reduced maintenance convenience that can occur when the outer shell 10 is made from the same structural component, and facilitates positioning and assembly. For example, the outer shell 10 may include a top shell and a bottom shell. The top shell and bottom shell can be connected and jointly enclose the cavity W of the detection device 100. The bottom shell refers to the bottom housing of the detection device 100, which serves to support and protect the internal components.

[0117] like Figure 1 As shown, the outer casing 10 may include a casing body 11 and a viewing window 12. The casing body 11 may enclose a cavity W forming the detection device 100. The casing body 11 has an opening communicating between the cavity W of the detection device 100 and the outside of the detection device 100. The viewing window 12 may be connected to the casing body 11 and close the opening. The detection beam emitted by the detection device 100 can be projected onto the environment to be detected outside the detection device 100 through the viewing window 12. The echo beam from the environment to be detected outside the detection device 100 can also enter the interior of the detection device 100 through the viewing window 12. The shape of the viewing window 12 may match the shape of the opening of the casing body 11.

[0118] Please refer to the following: Figure 2 and Figure 3The positioning post 30 can be fixedly connected to the inner surface of the housing 10 and protrude relative to the inner surface of the housing 10. The extending direction of the positioning post 30 can be perpendicular to the inner surface of the housing 10 to which it is connected. That is, the included angle between the positioning post 30 and the inner surface of the housing 10 to which it is connected can be 90° (the allowable tolerance range for the included angle is, for example, 86°, 87°, 88°, 89°, 91°, 92°, 93°, 94°, 95°, etc.). Alternatively, the extending direction of the positioning post 30 can also be inclined to the inner surface of the housing 10 to which it is connected. The positioning post 30 can pass through the mounting bracket 20.

[0119] The inner surface of the outer shell 10 is the inner wall of the cavity W described above. There can be one or more positioning posts 30. When there are multiple positioning posts 30, their structures can be similar, identical, or different. The multiple positioning posts 30 can be spaced apart on the inner surface of the outer shell 10. Each positioning post 30 is fixedly connected to the outer shell 10. The multiple positioning posts 30 can have the same protrusion height relative to the inner surface of the outer shell 10. Alternatively, the multiple positioning posts 30 can have different protrusion heights relative to the inner surface of the outer shell 10. For example, there can be four positioning posts 30. The four positioning posts 30 can be spaced apart on the inner surface of the outer shell 10 and have the same protrusion height relative to the inner surface of the outer shell 10. This allows the positioning posts 30 to have better stress consistency, facilitating subsequent assembly of the positioning posts 30 with the first shock-absorbing assembly.

[0120] Specifically, the positioning post 30 may include a first connecting end 31 and a second connecting end 32. The first connecting end 31 of the positioning post 30 may be fixedly connected to the inner surface of the housing 10. The positioning post 30 passes through the mounting bracket 20. The second connecting end 32 of the positioning post 30 may extend away from the inner surface of the housing 10 and protrude relative to the surface of the mounting bracket 20 opposite to the housing 10. The positioning post 30 may be provided with a positioning hole 33. The opening of the positioning hole 33 may be located on the end face of the second connecting end 32. The positioning hole 33 may be recessed from the end face of the second connecting end 32 towards the first connecting end 31. For example, the positioning hole 33 may be a threaded hole.

[0121] The positioning post 30 can be connected to the housing 10 to form an integral structure. With this configuration, the detection device 100 has fewer parts, which simplifies the manufacturing process and improves the production and assembly efficiency of the detection device 100. Exemplarily, the positioning post 30 and the housing 10 can be separately disposed and connected together by assembly methods such as welding or bonding to form an integral structure. Alternatively, the positioning post 30 and the housing 10 can be connected by a method such as integral molding to form an integral structure.

[0122] The positioning post 30 can be made of a material with a certain degree of hardness, such as metal or ceramic. The material of the positioning post 30 can be the same as that of the outer shell 10. Alternatively, the material of the positioning post 30 can be different from that of the outer shell 10.

[0123] It should be noted that the material, number, location, shape, and protrusion height of the positioning post 30 relative to the inner surface of the outer shell 10 of the positioning post 30 can be selected according to the actual application scenario of the detection device 100, and there are no strict restrictions on them.

[0124] Please refer to the following: Figure 3 , Figure 4 and Figure 5 , Figure 4 yes Figure 2 A schematic diagram of a portion of the mounting bracket 20 of the detection device 100 shown. Figure 5 yes Figure 2 A simplified schematic diagram of another part of the mounting bracket 20 of the detection device 100 shown.

[0125] The mounting bracket 20 can serve as the mounting base for the vibration source 50. The mounting bracket 20 can connect between the housing 10 and the vibration source 50, and is used to mount the vibration source 50 onto the housing 10, thereby achieving relative fixation between the vibration source 50 and the housing 10. Specifically, the mounting bracket 20 can be sleeved on the outside of the positioning post 30, allowing the positioning post 30 to pass through. The through-hole position of the positioning post 30 on the mounting bracket 20 can be located at the outer edge of the mounting bracket 20. For example, the mounting bracket 20 can be sleeved on the outside of multiple positioning posts 30, and located within the area enclosed by the multiple positioning posts 30.

[0126] The mounting bracket 20 may be provided with a first mounting hole 21. The first mounting hole 21 can penetrate the mounting bracket 20 along its thickness direction. That is, the first mounting hole 21 can be a through hole provided in the thickness direction of the mounting bracket 20. The first mounting hole 21 allows the positioning post 30 to pass through. The position of the first mounting hole 21 can correspond to the position of the positioning post 30, and the shape of the first mounting hole 21 can be adapted to the shape of the positioning post 30, so as to quickly align and assemble the first mounting hole 21 and the positioning post 30, improving the assembly performance between the mounting bracket 20 and the positioning post 30. Further, the central axis of the first mounting hole 21 can coincide with the central axis of the positioning post 30. That is, the central axis of the first mounting hole 21 can be coaxial with the central axis of the positioning post 30. For example, the first mounting hole 21 can be provided on the outer edge of the mounting bracket 20. The first mounting hole 21 can be a circular hole.

[0127] The number of first mounting holes 21 can be the same as the number of positioning posts 30, and there can be one or more of them. When there are multiple first mounting holes 21, the structures of the multiple first mounting holes 21 can be similar, identical, or different. The multiple first mounting holes 21 can be spaced apart along the circumferential direction of the mounting bracket 20 on its outer edge, wherein the circumferential direction of the mounting bracket 20 is the direction around its central axis. For example, the number of first mounting holes 21 can be four. The four first mounting holes 21 can be spaced apart at the four corners of the mounting bracket 20 along its circumferential direction. Each first mounting hole 21 can allow one positioning post 30 to pass through.

[0128] One possible implementation, such as Figure 4 As shown, the outer edge of the first mounting hole 21 can be spaced apart from the outer edge of the mounting bracket 20. The mounting bracket 20 may have a first notch 22. The first notch 22 can penetrate through the outer edge of the mounting bracket 20 and communicate with the first mounting hole 21. That is, the first notch 22 can be formed at the outer edge of the mounting bracket 20 and extend from the outer edge of the mounting bracket 20 to the outer edge of the first mounting hole 21 to communicate with the first mounting hole 21.

[0129] The number of first notches 22 can be the same as the number of first mounting holes 21, or there can be one or more. When there are multiple first notches 22, the structures of the multiple first notches 22 can be similar, identical, or different. The multiple first notches 22 can be arranged at intervals on the outer edge of the mounting bracket 20. Each first notch 22 penetrates the outer edge of the mounting bracket 20 and communicates with a first mounting hole 21. For example, the number of first notches 22 can be four. The four first notches 22 can be spaced apart at the four corners of the mounting bracket 20 and communicate with the four first mounting holes 21 located at the four corners of the mounting bracket 20, respectively.

[0130] Another possible implementation, such as Figure 5 As shown, unlike the previous embodiment, the mounting bracket 20 does not have a first notch 22. The first mounting hole 21 may include a first sub-hole 23 and a second sub-hole 24. The first sub-hole 23 and the second sub-hole 24 can be connected. The communication direction between the first sub-hole 23 and the second sub-hole 24 can be parallel to the mounting bracket 20. The central axis of the first sub-hole 23 can coincide with the central axis of the positioning post 30, that is, the central axis of the first sub-hole 23 can be coaxially arranged with the central axis of the positioning post 30. The diameter of the second sub-hole 24 can be larger than the diameter of the first sub-hole 23. The diameters of both the first sub-hole 23 and the second sub-hole 24 can be larger than the diameter at the connection point between the second sub-hole 24 and the first sub-hole 23. For example, the first mounting hole 21 can be a gourd-shaped hole.

[0131] Please refer to the following: Figure 2 , Figure 3 and Figure 6 , Figure 6 It is along Figure 2 The diagram shown is a partial structural diagram of the detection device 100 shown, with section line AA cutting through it.

[0132] In the embodiments of this application, the first vibration damping component 40 can be inserted through the mounting bracket 20. The first vibration damping component 40 can also be connected to the positioning post 30 to fix the mounting bracket 20 to the housing 10. The number of first vibration damping components 40 can be one or more. When there are multiple first vibration damping components 40, the structures of the multiple first vibration damping components 40 can be similar, identical, or different. The multiple first vibration damping components 40 can be distributed at intervals along the circumferential direction of the mounting bracket 20 on the outer edge of the mounting bracket 20. Each first vibration damping component 40 can be correspondingly disposed with a positioning post 30 and a first mounting hole 21 of the mounting bracket 20. For example, the number of first vibration damping components 40 can be four. The four first vibration damping components 40 can be distributed at intervals along the circumferential direction of the mounting bracket 20 at the four corners of the mounting bracket 20.

[0133] The first vibration damping component 40 may include a first vibration isolation sleeve 41 and a first locking structure 42. The first vibration isolation sleeve 41 may pass through the mounting bracket 20 and be sleeved on the outside of the positioning post 30. The first locking structure 42 may be inserted into the first vibration isolation sleeve 41 and abut against the first vibration isolation sleeve 41. The first locking structure 42 may also be connected to the positioning post 30.

[0134] The connection between the first locking structure 42 and the positioning post 30 can be detachable. That is, the first locking structure 42 can be detachably connected to the positioning post 30. With this configuration, the first locking structure 42 can be locked to the positioning post 30 to achieve a fixed connection between the first damping component and the positioning post 30. The first locking structure 42 can also be unlocked from the positioning post 30 to allow the first damping component to be detached from the positioning post 30. By making the first locking structure 42 detachably connected to the positioning post 30, the assembly process of the first damping component 40 can be simplified, facilitating its assembly and transportation. Furthermore, it allows for easy disassembly and repair or replacement of components when the first damping component 40 malfunctions, improving the overall assemblability of the first damping component 40. For example, the detachable connection between the first locking structure 42 and the positioning post 30 can be, but is not limited to, threaded connection, keyed connection, pin connection, riveting, snap-fit ​​connection, etc.

[0135] Alternatively, the connection between the first locking structure 42 and the positioning post 30 can also be a fixed connection. That is, the first locking structure 42 and the positioning post 30 are fixedly connected. For example, the fixed connection between the first locking structure 42 and the positioning post 30 can be welding, bonding, etc.

[0136] It is understandable that by inserting the first locking structure 42 into the first vibration isolation sleeve 41 and connecting the first locking structure 42 with the positioning post 30 nested in the first vibration isolation sleeve 41, the supporting performance of the positioning post 30 can be utilized to provide good assembly performance for the first locking structure 42, ensuring the assembly accuracy and fixation stability of the first locking structure 42, and thus achieving better reliability.

[0137] In the embodiments of this application, the first locking structure 42 can be used to pre-press the first vibration isolation sleeve 41 onto the outer shell 10 before locking it with the positioning post 30. That is, the first vibration isolation sleeve 41 has a pre-press amount in the clamping direction of the first locking structure 42 and the outer shell 10 (i.e., the axial direction of the first vibration isolation sleeve 41).

[0138] Pre-compression refers to applying a certain pressure (or compression) to the first vibration isolation sleeve 41 before use, so that the first vibration isolation sleeve 41 is in a pre-tightened state. Clamping direction refers to the direction in which the clamping force acts on the first vibration isolation sleeve 41. The direction of the clamping force can be vertical, horizontal, oblique, or a combination of multiple directions. Pre-compression amount refers to the amount of compression applied to the first vibration isolation sleeve 41 before installation or commissioning. This pre-compression ensures that the first vibration isolation sleeve 41 is under a certain stress state in its initial state, thereby optimizing its vibration isolation performance.

[0139] Understandably, on the one hand, the first vibration isolation sleeve 41, without preloading, may undergo significant deformation during initial loading, even exceeding its elastic range, leading to irreversible damage. Preloading allows the first vibration isolation sleeve 41 to enter a stable working state earlier, preventing damage due to excessive deformation in the early stages of use and improving its impact resistance. On the other hand, without preloading, the first vibration isolation sleeve 41 may have high initial stiffness, resulting in a high vibration transmission rate. Preloading reduces the initial stiffness of the first vibration isolation sleeve 41, decreasing the transmission of initial vibrations.

[0140] Furthermore, when the first vibration isolation sleeve 41 is not preloaded, its contact with the first locking structure 42 may be uneven. Preloading allows the first vibration isolation sleeve 41 to make better contact with the first locking structure 42 and the outer shell 10, increasing the actual contact area, reducing local stress concentration, and preventing vibration transmission due to poor contact, thereby improving the vibration isolation effect and the overall stability of the detection device 100. It also makes the stress distribution inside the first vibration isolation sleeve 41 more uniform, reducing local stress peaks and thus lowering the risk of fatigue damage.

[0141] In one possible implementation, the first vibration isolation sleeve 41 has a preload of 10%-30% (including the endpoint values ​​of 10% and 30%) in the clamping direction of the first locking structure 42 and the housing 10.

[0142] The first vibration isolation sleeve 41 is a structural component with a certain degree of elasticity. Before being compressed, it is in a free state. After being compressed, it undergoes elastic deformation and compression, and it rebounds after the pressure is removed. The pre-compression amount of the first vibration isolation sleeve 41 in the clamping direction of the first locking structure 42 and the outer shell 10 refers to the amount by which the first vibration isolation sleeve 41 is pre-compressed in the clamping direction of the first locking structure 42 and the outer shell 10 (i.e., the axial direction of the first vibration isolation sleeve 41). Structurally, this can be expressed as the height of the first vibration isolation sleeve 41 after pre-compression being reduced to a certain extent relative to its free height before being pre-compressed.

[0143] Therefore, the 10%-30% preload of the first vibration isolation sleeve 41 in the clamping direction between the first locking structure 42 and the outer shell 10 means that if the free height of the first vibration isolation sleeve 41 before preloading is H, then in the clamping direction between the first locking structure 42 and the outer shell 10, the height of the first vibration isolation sleeve 41 after preloading will be reduced by 0.1H to 0.3H (including the endpoint values ​​of 0.1H and 0.3H) relative to the free height H of the first vibration isolation sleeve 41. The specific value of H can be selected according to the actual application scenario, and the embodiments of this application do not impose strict limitations on this.

[0144] It is understood that by setting the preload of the first vibration isolation sleeve 41 in the clamping direction of the first locking structure 42 and the outer shell 10 within the aforementioned range, the first vibration isolation sleeve 41 can have an appropriate preload to better perform its vibration isolation function during operation, increase the rigidity of the first damping component, reduce vibration transmission, and improve the stability and reliability of the first damping component.

[0145] Of course, in some other embodiments, the first vibration isolation sleeve 41 may not have a preload in the clamping direction of the first locking structure 42 and the outer shell 10, and this is not strictly limited.

[0146] The relative positions of the components in the first vibration damping assembly 40 have been briefly described above. The following section will describe in detail the structure of each component in the first vibration damping assembly 40 and the connection relationship between them, with reference to the accompanying drawings.

[0147] Please refer to the following: Figure 6 , Figure 7 , Figure 8 and Figure 9 , Figure 7 yes Figure 2 The diagram shows a partial structural representation of the detection device 100. Figure 8 yes Figure 2 The diagram shows a structural schematic of the first vibration isolation sleeve 41 of the detection device 100 at one angle. Figure 9 It is along Figure 8 The diagram shows a cross-sectional view of the first vibration isolation sleeve 41 obtained by cutting along the cutting line BB.

[0148] The first vibration isolation sleeve 41 can be installed in the first mounting hole 21 of the mounting bracket 20 and surround the positioning post 30. The central axis of the first vibration isolation sleeve 41 can be aligned with the central axis of the first mounting hole 21 and the central axis of the positioning post 30. That is, the central axis of the first vibration isolation sleeve 41, the central axis of the first mounting hole 21, and the central axis of the positioning post 30 are all coaxial.

[0149] The first vibration isolation sleeve 41 can be in the form of a hollow sleeve. The first vibration isolation sleeve 41 can be flexible and have a certain elastic deformation capacity, allowing it to elastically deform under stress and return to its original shape after the external force is removed. The first vibration isolation sleeve 41 can be made of any elastic material capable of isolating vibration and impact. For example, the material of the first vibration isolation sleeve 41 can include rubber materials, such as ethylene propylene diene monomer (EPDM), natural rubber (NR), styrene-butadiene rubber (SBR), butadiene rubber (BR), isoprene rubber (IR), nitrile rubber (NBR), chloroprene rubber (CR), isobutylene rubber (IIR), silicone, etc.

[0150] In the axial direction, the first vibration isolation sleeve 41 can be clamped between the first locking structure 42 and the outer shell 10, wherein the axial direction of the first vibration isolation sleeve 41 refers to the direction of the central axis of the first vibration isolation sleeve 41. In the radial direction, the first vibration isolation sleeve 41 can be clamped between the first positioning post 30 and the mounting bracket 20, wherein the radial direction of the first vibration isolation sleeve 41 refers to the direction perpendicular to the central axis of the first vibration isolation sleeve 41.

[0151] It is understandable that by clamping the first vibration isolation sleeve 41 in both the axial and radial directions, the first vibration isolation sleeve 41 can be fixed in the assembly position by the cooperation of the first locking structure 42, the outer shell 10, the mounting bracket 20 and the positioning post 30, ensuring the relative positional accuracy between the first vibration isolation sleeve 41 and other surrounding components, ensuring assembly quality, and improving the connection strength and reliability between the first vibration isolation sleeve 41 and other surrounding components.

[0152] The first vibration isolation sleeve 41 may include a first contact end 411 and a second contact end 412. The first contact end 411 may contact the first locking structure 42. The second contact end 412 may contact the outer casing 10. The first vibration isolation sleeve 41 may be provided with a first through hole 413. The first through hole 413 may penetrate the first vibration isolation sleeve 41 along its height direction. That is, the first through hole 413 may extend from the first contact end 411 to the second contact end 412, and penetrate the end faces of the first contact end 411 and the second contact end 412. The first through hole 413 can accommodate the positioning post 30 and part of the first damping assembly. The inner surface of the first through hole 413 may be interference-fitted with the outer surface of the positioning post 30 to enhance the connection stability and reliability between the first vibration isolation sleeve 41 and the positioning post 30.

[0153] The first through hole 413 may include a first hole 4131 and a second hole 4132. The first hole 4131 and the second hole 4132 are sequentially arranged and connected along the height direction of the first vibration isolation sleeve 41. The first hole 4131 and the second hole 4132 are coaxially arranged. The opening of the first hole 4131 away from the second hole 4132 is located on the end face of the first contact end 411. The opening of the second hole 4132 away from the first hole 4131 is located on the end face of the second contact end 412. The diameter of the first hole 4131 may be smaller than the diameter of the second hole 4132. The depth of the first hole 4131 may be smaller than the depth of the second hole 4132. The first hole 4131 and the second hole 4132 can cooperate to accommodate a portion of the first vibration damping component 40. The second hole 4132 can accommodate the positioning post 30.

[0154] Please refer to the following: Figure 7 , Figure 8 and Figure 9The outer surface of the first vibration isolation sleeve 41 may be recessed with a first mounting groove 414. The opening of the first mounting groove 414 may be located on the outer surface of the first vibration isolation sleeve 41. The first mounting groove 414 may be recessed from the outer surface of the first vibration isolation sleeve 41 to the interior of the first vibration isolation sleeve 41. The first mounting groove 414 may extend along the circumferential direction of the first vibration isolation sleeve 41, wherein the circumferential direction of the first vibration isolation sleeve 41 may be the direction surrounding the central axis of the first vibration isolation sleeve 41. Further, the connection between the inner wall of the first mounting groove 414 and the outer surface of the first vibration isolation sleeve 41 may be a curved transition, wherein the curved transition refers to the design of using an arc or other arc-shaped structure to achieve a smooth transition at the intersection of the inner wall of the first mounting groove 414 and the outer surface of the first vibration isolation sleeve 41. This design can not only prevent the mounting bracket 20 from scratching the first vibration isolation sleeve 41 during the assembly process of the mounting bracket 20 and the first vibration isolation sleeve 41. It can also provide a certain guiding effect for the mounting bracket 20 to be inserted into the first mounting groove 414 during the assembly process of the mounting bracket 20 and the first vibration isolation sleeve 41.

[0155] For example, the first mounting groove 414 may be provided in the intermediate region between the first contact end 411 and the second contact end 412. The first mounting groove 414 may be an annular groove surrounding the outer surface of the first vibration isolation sleeve 41. Alternatively, the first mounting groove 414 may also be an arcuate groove extending in the circumferential direction of the first vibration isolation sleeve 41.

[0156] It should be noted that the shape of the first mounting groove 414, the extension length of the first mounting groove 414, the recess depth of the first mounting groove 414 relative to the outer surface of the first vibration isolation sleeve 41, the setting position of the first mounting groove 414, and other characteristic parameters of the first mounting groove 414 can be selected according to the actual application scenario of the first vibration isolation sleeve 41, and there are no strict restrictions on them.

[0157] In the embodiments of this application, the first vibration isolation sleeve 41 can be engaged with the first mounting hole 21 of the mounting bracket 20 via the first mounting groove 414. It is understood that when the first vibration isolation sleeve 41 is engaged with the mounting bracket 20, the first vibration isolation sleeve 41 can pass through the first mounting hole 21 of the mounting bracket 20, and part of the mounting bracket 20 can be located in the first mounting groove 414 of the first vibration isolation sleeve 41. This allows the first vibration isolation sleeve 41 and the mounting bracket 20 to be mutually embedded, thereby making the relative fixing relationship between the first vibration isolation sleeve 41 and the mounting bracket 20 more stable and reliable. This enhances the connection strength between the first vibration isolation sleeve 41 and the mounting bracket 20, and facilitates disassembly and assembly.

[0158] In one possible implementation, please refer to [the relevant documentation]. Figure 4 and Figure 7The mounting bracket 20 may also be provided with the first notch 22 mentioned above. The first notch 22 can expose a portion of the first mounting groove 414 of the first vibration isolation sleeve 41.

[0159] It is understandable that by providing a first notch 22 on the mounting bracket 20, and having the first notch 22 penetrate the outer edge of the mounting bracket 20 and communicate with the first mounting hole 21, on the one hand, it is convenient to insert the first vibration isolation sleeve 41 into the first mounting hole 21 from the position of the first notch 22 when assembling the first vibration isolation sleeve 41 with the mounting bracket 20, which is beneficial to improving the assembly efficiency and ease of assembly. On the other hand, since the mounting bracket 20 only contacts a portion of the inner surface of the first mounting groove 414, there will be a certain gap between the mounting bracket 20 and the remaining portion of the inner surface of the first mounting groove 414, except for the contact point between the mounting bracket 20 and the inner surface of the first mounting groove 414. This allows the force exerted by the mounting bracket 20 on the first vibration isolation sleeve 41 during assembly with the mounting bracket 20 to be dispersed from the contact point between the mounting bracket 20 and the inner surface of the first mounting groove 414 to the gap between the inner surfaces of the mounting bracket 20 and the first mounting groove 414 (i.e., the location of the first notch 22). This helps to avoid stress concentration at the contact point between the mounting bracket 20 and the inner surface of the first mounting groove 414, which could lead to cracking of the first vibration isolation sleeve 41, thus increasing the connection stability and reliability between the mounting bracket 20 and the first vibration isolation sleeve 41.

[0160] For another possible implementation, please refer to [reference needed]. Figure 5 and Figure 10 , Figure 10 yes Figure 2 The diagram shows another structural representation of a portion of the detection device 100. Unlike the previous embodiment, the mounting bracket 20 does not have a first notch 22. The first mounting hole 21 may include the first sub-hole 23 and the second sub-hole 24 described above.

[0161] In this embodiment, the first vibration isolation sleeve 41 can be inserted into the first mounting hole 21 and can be switched between the first sub-hole 23 and the second sub-hole 24. It is understood that since the first mounting hole 21 has two interconnected sub-holes with different diameters, the first mounting hole 21 can have a gourd-like hole structure. This gourd-like hole structure allows the first vibration isolation sleeve 41 to have a certain adjustment space within the first mounting hole 21, dispersing the stress in the first mounting hole 21, avoiding the occurrence of stress concentration points, thereby improving the structural strength and service life of the first mounting hole 21, and facilitating the fixing and positioning of the first vibration isolation sleeve 41.

[0162] In this embodiment, the first vibration isolation sleeve 41 can be inserted through the first sub-hole 23 to be fixed relative to the mounting bracket 20. The first vibration isolation sleeve 41 is also sleeved on the outside of the positioning post 30.

[0163] Understandably, when the first vibration isolation sleeve 41 needs to be assembled onto the mounting bracket 20, the first vibration isolation sleeve 41 can first be inserted into the second sub-hole 24 with a relatively larger diameter, and then gradually moved from the second sub-hole 24 to the first sub-hole 23 with a relatively smaller diameter, finally achieving relative fixation with the mounting bracket 20 at the first sub-hole 23. When the first vibration isolation sleeve 41 needs to be removed from the mounting bracket 20, the first vibration isolation sleeve 41 can first be unlocked from the mounting bracket 20 at the first sub-hole 23, and then gradually moved from the first sub-hole 23 to the second sub-hole 24 with a relatively larger diameter, finally detaching from the mounting bracket 20 at the position of the second sub-hole 24. By switching the first vibration isolation sleeve 41 between the first sub-hole 23 and the second sub-hole 24, the installation and removal of the first vibration isolation sleeve 41 can be facilitated.

[0164] Please refer to it again. Figure 6 ,exist Figure 6 In the diagram, the dashed arrows indicate conductive paths. However, it should be understood that the dashed arrows are only for the convenience of illustrating that there is a conductive path between the first vibration isolation sleeve 41 and the mounting bracket 20, but do not represent the actual path and actual length of the conductive path.

[0165] In the embodiments of this application, the first vibration isolation sleeve 41 can form a current path between the mounting bracket 20 and the outer shell 10. A conductive path is formed at the contact point between the first vibration isolation sleeve 41 and the mounting bracket 20. It can be understood that since the first vibration isolation sleeve 41 is in contact with both the mounting bracket 20 and the outer shell 10, the conductive path formed at the contact point between the first vibration isolation sleeve 41 and the mounting bracket 20 can form a current path of "mounting bracket 20 - first vibration isolation sleeve 41 - outer shell 10", enabling the mounting bracket 20 and the outer shell 10 to achieve electrical conduction through the first vibration isolation sleeve 41, thereby enabling the mounting bracket 20 to be grounded. That is, the first vibration isolation sleeve 41 can have both vibration isolation and grounding functions, which is beneficial to ensuring the normal operation of the detection device 100 and improving the stability of the detection device 100.

[0166] In one possible implementation, the first vibration isolation sleeve 41 may be made entirely of a conductive material. Alternatively, the portion of the first vibration isolation sleeve 41 located between the mounting bracket 20 and the outer casing 10 may be made of a conductive material. For example, the conductive material may be conductive rubber.

[0167] Therefore, it can be ensured that a current path can be formed between the first vibration isolation sleeve 41 and the mounting bracket 20, as well as between the first vibration isolation sleeve 41 and the outer shell 10, thereby forming a current path of "mounting bracket 20-first vibration isolation sleeve 41-outer shell 10" and realizing the grounding function of the first vibration isolation sleeve 41.

[0168] In another possible implementation, the detection device 100 may further include a conductive structure (not shown). The conductive structure may be connected to at least one of the mounting bracket 20 and the first vibration isolation sleeve 41, and is located at the junction of the mounting bracket 20 and the first vibration isolation sleeve 41. Exemplarily, the conductive structure may be a conductive film. The conductive film may be attached to the outer surface of the first vibration isolation sleeve 41.

[0169] Therefore, it can be ensured that a current path can be formed between the first vibration isolation sleeve 41 and the mounting bracket 20, so as to realize the grounding function of the first vibration isolation sleeve 41.

[0170] Please refer to the following: Figure 8 and Figure 9 The first vibration isolation sleeve 41 may also be provided with a first groove 415. The opening of the first groove 415 may be located on the end face of the first contact end 411. The first groove 415 may be recessed from the end face of the first contact end 411 toward the second contact end 412. The first groove 415 may communicate with the first through hole 413 and be coaxially arranged. The first groove 415 may be arranged around the periphery of the first hole 4131 and communicate with both the first hole 4131 and the second hole 4132. The depth of the first groove 415 may be the same as the depth of the first hole 4131.

[0171] Furthermore, the outer diameter of the first vibration isolation sleeve 41 can gradually decrease from the first contact end 411 to the second contact end 412 and then remain constant. The first mounting groove 414 mentioned above can be located in the portion of the first vibration isolation sleeve 41 where the outer diameter remains constant.

[0172] Please refer to the following: Figure 6 and Figure 11 , Figure 11 yes Figure 2 A schematic diagram of the first locking structure 42 of the detection device 100 shown.

[0173] The first locking structure 42 may include a first locking member 421 and a first washer 422. The first locking member 421 may be inserted into and connected to the positioning post 30. A portion of the first locking member 421 may be located within the positioning hole 33 of the positioning post 30. That is, the first locking member 421, the positioning post 30, and the first vibration isolation sleeve 41 are sequentially sleeved from the inside out. The outer surface of the first locking member 421 located in the positioning hole 33 may be interference-fitted with the inner surface of the positioning hole 33 to enhance the connection stability and reliability between the first locking member 421 and the positioning post 30. For example, the first locking member 421 may be a screw.

[0174] The connection between the first locking member 421 and the positioning post 30 can be detachable. That is, the first locking member 421 can be detachably connected to the positioning post 30. For example, the detachable connection between the first locking member 421 and the positioning post 30 can be, but is not limited to, threaded connection, keyed connection, pin connection, riveting, snap-fit ​​connection, etc. Alternatively, the connection between the first locking member 421 and the positioning post 30 can also be fixed. That is, the first locking member 421 and the positioning post 30 are fixedly connected. For example, the fixed connection between the first locking structure 42 and the positioning post 30 can be welding, bonding, etc.

[0175] The first washer 422 can be sleeved on the outside of the first locking member 421 and abut against the first vibration isolation sleeve 41, with at least a portion of the first washer 422 located inside the first vibration isolation sleeve 41. Exemplarily, the first washer 422 can be entirely located within the first groove 415 of the first vibration isolation sleeve 41. The surface of the first washer 422 facing away from the bottom wall of the first groove 415 can be flush with the end face of the first contact end 411 of the first vibration isolation sleeve 41.

[0176] It is understandable that by inserting the first locking member 421 into the first vibration isolation sleeve 41 and connecting the first locking member 421 with the positioning post 30 nested in the first vibration isolation sleeve 41, the supporting performance of the positioning post 30 can be utilized to provide good assembly performance for the first locking member 421, ensuring the assembly accuracy and fixation stability of the first locking member 421, and thus achieving better reliability.

[0177] Furthermore, a first shim 422 is provided between the first locking member 421 and the first vibration isolation sleeve 41. On one hand, the first shim 422 can increase the friction between the first locking member 421 and the first vibration isolation sleeve 41, thereby preventing the first locking member 421 from loosening due to vibration or impact during use. On the other hand, the first shim 422 can act as a buffer layer to protect the surface of the first vibration isolation sleeve 41 from damage, preventing the first locking member 421 from causing scratches or wear on the surface of the first vibration isolation sleeve 41 during the connection with the positioning post 30. It can also be used to adjust the gap between the first connector and the positioning post 30, ensuring the tightness and consistency of the connection.

[0178] Please refer to the following: Figure 6 and Figure 12 , Figure 12 It is along Figure 2 The diagram shown shows another state of the structure of the detection device 100, cut by the section line AA.

[0179] In embodiments of this application, the first locking member 421 may include a first state and a second state.

[0180] like Figure 12 As shown, when the first locking member 421 is in the first state, there is a gap between the first pad 422 and the second connecting end 32 of the positioning post 30, and the first vibration isolation sleeve 41 is pressed onto the outer shell 10 by the first pad 422. The height of the first vibration isolation sleeve 41 can be a first height H1. In this state, the first vibration isolation sleeve 41 can be in a compressed state. Alternatively, the first vibration isolation sleeve 41 can be in a pre-compression state. For example, when the first vibration isolation sleeve 41 is in the compressed state, the gap between the first pad 422 and the second connecting end 32 of the positioning post 30 can be caused by the detection device 100 loosening due to vibration. When the first vibration isolation sleeve 41 is in the pre-compression state, the first pad 422 can act as the object that applies pre-pressure to the first vibration isolation sleeve 41 in the first locking structure 42, so that the first vibration isolation sleeve 41 can maintain a certain tension, thereby improving the overall impact resistance of the first vibration isolation sleeve 41.

[0181] like Figure 6 As shown, when the first locking member 421 is in the second state, the first washer 422 abuts against the end of the positioning post 30 away from the outer shell 10, and the first vibration isolation sleeve 41 is pressed onto the outer shell 10 by the first washer 422. The height of the second vibration isolation sleeve 2410 can be a second height H2. The second height H2 can be less than the first height H1. In this state, the first vibration isolation sleeve 41 can be in a compressed state. In the axial direction of the first vibration isolation sleeve 41, the first vibration isolation sleeve 41 is clamped between the first washer 422 and the outer shell 10, thereby fixing the first vibration isolation sleeve 41 and the mounting bracket 20 relative to the outer shell 10.

[0182] In embodiments of this application, the detection device 100 may further include a driveable component (not shown) and a motor (not shown). Both the motor and the driveable component may be located within the cavity W. The motor is connected to the mounting bracket 20 and is driveably connected to the driveable component. The motor is used to drive the driveable component to move. The motor may be the vibration source 50 described above. A drive connection refers to a connection form that connects the motor, which serves as a power source, to the driveable component, which serves as an actuator, to achieve effective power transmission and motion conversion. Drive connections may include fixed connections and kinematic pair connections (such as lower pair connections and higher pair connections). For example, the driveable component may be a reflector, a rotating mirror, etc.

[0183] It should be noted that the connection method between the motor and the mounting bracket 20 can be selected according to the actual application scenario, such as fixed connection, detachable connection, or rotatable connection. The vibration source 50 is not limited to the motor; any component capable of generating vibration and noise is within the scope of protection claimed in the embodiments of this application. Furthermore, the internal vibration isolation scheme provided in the embodiments of this application is not only applicable to the detection device 100, but also applicable to any structure with an internal vibration source 50 that needs to reduce vibration and noise; no strict limitations are imposed.

[0184] In embodiments of this application, the detection device 100 may further include a light emitter (not shown), a light receiver (not shown), and a scanner (not shown). The light emitter, light receiver, and scanner may all be located within the cavity W. The light emitter can be used to emit a detection beam towards the target object. The light receiver can be used to receive the echo beam generated after the detection beam is reflected by the target object. The scanner can be used to transmit the detection beam to the outside of the detection device 100 and return the echo beam to the inside of the detection device 100. The scanner can increase the detection range of the detection device 100. Further, the detection device 100 may also include a processor. The processor may be electrically connected to both the light receiver and the light emitter. The light receiver can receive the echo beam and convert it into an electrical signal. The processor can perform data processing on the electrical signal to obtain associated information about the target object, such as position, distance, and speed information.

[0185] The scanner may include the mounting bracket 20 and vibration source 50 described above. For example, the scanner may include the mounting bracket 20, a motor, and a driven component. The target object refers to the object being detected by the detection device 100, which may be, but is not limited to, vehicles, pedestrians, buildings, vegetation, and the ground.

[0186] In one possible implementation, the scanner can be used to reflect the probe beam emitted by the light emitter to a detection area outside the detection device 100. Specifically, the scanner can change its scanning angle by rotating around its scanning axis, so that the scanner reflects the probe beam from the light emitter to different positions in the detection area at different scanning angles, thereby achieving scanning of the detection area. Furthermore, the scanner can also be used to reflect the echo beam from the detection area to the light receiver.

[0187] Embodiments of this application also provide a terminal. The terminal may include the detection device 100 described above. The terminal may be a vehicle, drone, robot, or other intelligent terminal or means of transportation. It should be understood that "vehicle" here is a vehicle in a broad sense, and may include means of transportation (such as commercial vehicles, passenger cars, motorcycles, flying cars, trains, etc.), industrial vehicles (such as forklifts, trailers, tractors, etc.), engineering vehicles (such as excavators, bulldozers, cranes, etc.), agricultural equipment (such as lawnmowers, harvesters, etc.), etc. Similarly, a robot may be an automated guided vehicle, a walking conversational robot, a service robot, etc.

[0188] Please see Figure 13 , Figure 13 This is a schematic diagram of a terminal 200 provided in an embodiment of this application. Figure 13 The installation location of the detection device 100 is only an example.

[0189] In the embodiments of this application, the detection device 100 can be disposed at various locations on the terminal 200. The number of detection devices 100 can be one or more. When there are multiple detection devices 100, they can be spaced apart on the terminal 200. For example, the detection devices 100 can be disposed in any one or more of the four directions (front, back, left, and right) of the terminal 200 to perceive the surrounding environment of the terminal 200 and obtain the associated information of target objects in the surrounding environment.

[0190] In one possible application scenario, let's take a LiDAR detector (100) and a vehicle as an example. The LiDAR can be positioned in any one or more of the four directions (front, rear, left, and right) of the vehicle to perceive the surrounding environment and obtain correlation information about target objects. This correlation information can be used to control the vehicle or assist the driver. The LiDAR can also be located on the top of the cockpit, the front of the vehicle, the side of the vehicle, or the rear of the vehicle. For example... Figure 13 This example uses a lidar unit located at the front of the vehicle and on the top of the cockpit.

[0191] Please refer to the following: Figure 13 and Figure 14 , Figure 14 It is along Figure 13 The diagram shows a simplified cross-sectional view of a portion of the structure of a terminal 200 obtained by cutting along section line CC. Among them, Figure 14 The purpose is merely to illustratively describe the connection relationships of the various components in terminal 200, and is not to specifically limit the connection positions, specific structures, or quantities of the various components. Furthermore, the structures illustrated in the embodiments of this application do not constitute a specific limitation on terminal 200. In other embodiments of this application, terminal 200 may include... Figure 14This may involve more or fewer components, or combining certain components, or splitting certain components, or different component arrangements. Figure 14 The components shown can be implemented in hardware, software, or a combination of both.

[0192] In embodiments of this application, the terminal 200 may further include an adapter bracket 210, a decorative cover 220, and a carrier 230. The decorative cover 220 may be connected to the carrier 230 and together with the carrier 230 form a receiving cavity Q. At least a portion of the adapter bracket 210 may be located within the receiving cavity Q. The adapter bracket 210 may be connected to the carrier 230 and to the decorative cover 220. The detection device 100 may be located within the receiving cavity Q. The detection device 100 may be connected to the adapter bracket 210. The detection device 100 may also be connected to the carrier 230 via the adapter bracket 210. That is, the decorative cover 220 may be mounted on the carrier 230. The adapter bracket 210 may be mounted on both the carrier 230 and the decorative cover 220. The detection device 100 may be mounted on the adapter bracket 210, and at least a portion of both the adapter bracket 210 and the detection device 100 may be located within the receiving cavity Q.

[0193] For example, taking the detection device 100 as a lidar, the terminal 200 as a vehicle, and the vehicle body 230 as an example, the lidar can be positioned at the front roof crossbeam of the vehicle body.

[0194] In embodiments of this application, the terminal 200 may further include a second vibration damping component 240. The second vibration damping component 240 may be connected to any one or a combination of the following locations: between the adapter bracket 210 and the carrier 230, between the housing 10 of the detection device 100 and the adapter bracket 210, between the adapter bracket 210 and the decorative cover 220, and between the housing 10 of the detection device 100 and the decorative cover 220 (if applicable).

[0195] The number of second vibration damping components 240 can be multiple. The structures of the multiple second vibration damping components 240 can be similar, identical, or different. The multiple second vibration damping components 240 can be spaced apart and distributed at any one or a combination of several locations: between the adapter bracket 210 and the carrier 230, between the housing 10 of the detection device 100 and the adapter bracket 210, between the adapter bracket 210 and the decorative cover 220, and between the housing 10 of the detection device 100 and the decorative cover 220 (if applicable). For example, the number of third vibration damping components can also be multiple. The multiple third vibration damping components can be located between the adapter bracket 210 and the carrier 230, between the housing 10 of the detection device 100 and the adapter bracket 210, and between the adapter bracket 210 and the decorative cover 220.

[0196] It is understandable that, based on the existing first vibration damping component 40 inside the detection device 100, by adding a second vibration damping component 240 outside the detection device 100, the vibration inside the detection device 100 can be attenuated layer by layer through the vibration isolation effect of the second vibration damping component 240, so as to further reduce or even eliminate the vibration, thereby reducing noise and effectively improving the comfort of the driver and passengers.

[0197] It should be noted that the structure of the second vibration damping component 240 can be set with reference to the structure of the first vibration damping component 40 described above, or it can be set with any structure that can reduce vibration and isolate noise. The embodiments of this application do not impose strict limitations on the structure of the second vibration damping component 240, as long as it can achieve the function of reducing vibration and noise.

[0198] The following description will exemplify the possible structure of the second vibration damping component 240 through two possible implementations, but it should be understood that it is not limited thereto.

[0199] In one possible implementation, please refer to [the relevant documentation]. Figure 15 and Figure 16 , Figure 15 yes Figure 14 The diagram shows an assembly structure of the second vibration damping component 240 of the terminal 200. Figure 16 It is along Figure 15 The diagram shows a cross-section obtained by cutting along the cutting line DD.

[0200] In this embodiment, the second vibration damping component 240 is connected between the detection device 100 and the adapter bracket 210 as an example for explanation, but it should be understood that this is not the only limitation.

[0201] The second vibration damping component 240 may include a second vibration isolation sleeve 2410 and a second locking structure 2420. The second vibration isolation sleeve 2410 may be inserted through the adapter bracket 210. The second locking structure 2420 may be inserted through the housing 10 of the detection device 100 and the second vibration isolation sleeve 2410, and fix the housing 10 of the detection device 100 to the adapter bracket 210, thereby achieving relative fixation between the detection device 100 and the adapter bracket 210.

[0202] The second locking structure 2420 may include a second locking member 2430, a second washer 2440, a bushing 2450, and a fastener 2460. The second washer 2440, bushing 2450, and fastener 2460 may all be fitted onto the second locking member 2430. The second vibration-damping sleeve 2410 may be fitted onto the outside of the bushing 2450 and pass through the adapter bracket 210. The second locking member 2430 may pass through the housing 10, second washer 2440, bushing 2450, second vibration-damping sleeve 2410, adapter bracket 210, and fastener 2460 of the detection device 100. The second washer 2440 may be located between the housing 10 and one end of the bushing 2450 of the detection device 100. The fastener 2460 may be located on the side of the adapter bracket 210 away from the housing 10 of the detection device 100 and also at the other end of the bushing 2450. Fastener 2460 can be locked with second locking member 2430. For example, second locking member 2430 can be a screw. Fastener 2460 can be a nut.

[0203] It is understandable that the deformation of the second vibration isolation sleeve 2410 in the second vibration damping component 240 can convert the relative vibration or impact energy between the detection device 100 and the adapter bracket 210 in the axial and radial directions into the deformation energy of the second vibration isolation sleeve 2410, thereby playing the role of vibration isolation and buffering, so as to reduce vibration noise and reduce the problem of reduced reliability of the detection device 100 caused by vibration.

[0204] Please see Figure 17 , Figure 17 yes Figure 15 The diagram shows the structure of the second vibration isolation sleeve 2410 of the second vibration damping assembly 240. In this embodiment, the second vibration isolation sleeve 2410 may include a first end 2411 and a second end 2412. The first end 2411 may be provided with a serrated structure 2413, and / or, the second end 2412 may be provided with a serrated structure 2413. Exemplarily, both the first end 2411 and the second end 2412 of the second vibration isolation sleeve 2410 may be provided with a serrated structure 2413.

[0205] It is understandable that by providing a serrated structure 2413 at the first end 2411 and / or the second end 2412 of the second vibration isolation sleeve 2410, the stiffness of the second vibration isolation sleeve 2410 can be effectively reduced, the vibration frequency can be lowered, and vibration transmission can be mitigated. In addition, the serrated structure 2413 can also reduce the contact area between the second vibration isolation sleeve 2410 and the side to be connected, thereby improving the vibration isolation rate.

[0206] For another possible implementation, please refer to [reference needed]. Figure 18 and Figure 19 , Figure 18 yes Figure 14A schematic diagram of another assembly structure of the second vibration damping component 240 of the terminal 200 shown. Figure 19 It is along Figure 18 The diagram shows a cross-section obtained by cutting along the section line EE.

[0207] In this embodiment, the second vibration damping component 240 is connected between the adapter bracket 210 and the decorative cover 220 as an example for explanation, but it should be understood that it is not limited thereto.

[0208] In this embodiment, the contents that are the same as in the previous embodiment will not be repeated. The difference is that the second vibration damping component 240 may include a second vibration isolation sleeve 2410 and a second locking structure 2420. The second vibration isolation sleeve 2410 can be inserted through the adapter bracket 210. The second locking structure 2420 can be inserted through the decorative cover 220 and the second vibration isolation sleeve 2410, and fix the decorative cover 220 to the adapter bracket 210, thereby achieving relative fixation between the decorative cover 220 and the adapter bracket 210.

[0209] The second locking structure 2420 may include a second locking member 2430, a second washer 2440, and a bushing 2450. The second washer 2440 and the bushing 2450 may both be fitted onto the second locking member 2430. The second vibration-damping sleeve 2410 may be fitted onto the outside of the bushing 2450 and pass through the adapter bracket 210. The second locking member 2430 may pass through the decorative cover 220, the second washer 2440, the bushing 2450, the second vibration-damping sleeve 2410, and the adapter bracket 210.

For example, the second locking member 2430 may be a screw. The decorative cover 220 may have a threaded hole.

[0210] It is understandable that the deformation of the second vibration isolation sleeve 2410 in the second vibration damping component 240 can convert the relative vibration or impact energy between the decorative cover 220 and the adapter bracket 210 in the axial and radial directions into the deformation energy of the second vibration isolation sleeve 2410, thereby playing the role of vibration isolation and buffering, so as to reduce vibration noise and reduce the problem of reduced reliability of the detection device 100 caused by vibration.

[0211] In this embodiment, the structure of the second vibration isolation sleeve 2410 can be referred to the description of the previous embodiment, and will not be repeated here.
