[0035] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0036] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0037] See also Figure 1 , the embodiment of the present application provides a movable device 200, and the movable device 200 includes a sensor assembly 100 and a device body 300. In some embodiments, the movable device 200 is a car, the device body 300 is a car body, and the sensor assembly 100 is mounted on the car body; it can be understood that in other implementations of the present application, the movable device 200 can also be a device other than a car equipped with the sensor assembly 100, such as a drone, a robot, etc., and the embodiment of the present application is not limited to this.

[0038] See also Figure 2 The sensor assembly 100 includes a vibration reduction bracket 4 and a sensor 5 connected to the vibration reduction bracket 4, and the vibration reduction bracket 4 is used to be connected to the device body 300, which is conducive to attenuating the vibration impact generated by the sensor 5 and transmitting it to the device body 300, and attenuating the vibration impact of the device body 300 and transmitting it to the sensor 5. It can be understood that the sensor 5 can be a laser radar, an image sensor, a millimeter wave radar, etc., and this application does not limit this.

[0039] For further information, see Figure 3 , the elastic center b of the vibration-damping bracket 4 roughly coincides with the projection of the total center of mass c of the sensor 5 and the vibration-damping bracket 4 on the installation plane of the vibration-damping bracket 4. Among them, the total center of mass c is the center of the total mass of the vibration-damping bracket 4 and the sensor 5, and is an imaginary point where the mass of the vibration-damping bracket 4 and the sensor 5 is concentrated. The elastic center b of the vibration-damping bracket 4 is determined by the stiffness and geometric distribution position of the shock absorber 1. Theoretically, if the elastic center b of the vibration-damping bracket 4 roughly coincides with the projection of the total center of mass c of the sensor 5 and the vibration-damping bracket 4 on the installation plane of the vibration-damping bracket 4, the vibration of the vibration-damping bracket 4 in the direction perpendicular to the movement of the installation plane can be decoupled. Among them, the vibration decoupling of the vibration-damping bracket 4 in the direction perpendicular to the movement of the installation plane means that the free vibration of the vibration-damping bracket 4 in the direction perpendicular to the installation plane of the vibration-damping bracket 4 is independent of the free vibration in other directions.

[0040] It should be noted that the mounting surface on the device body 300 for mounting the vibration-damping bracket 4 can be a horizontal plane, an inclined plane at an angle to the horizontal plane, a curved surface, etc., and can be flexibly adjusted according to actual needs, and there is no limitation on this. Among them, if the mounting surface is a horizontal plane or an inclined plane at an angle to the horizontal plane, then the mounting surface is the mounting plane of the vibration-damping bracket 4; if the mounting surface is a curved surface, the mounting plane of the vibration-damping bracket 4 can be a plane determined by one or more connection points that are roughly perpendicular to the vibration-damping bracket 4 and the device body 300; for example, there are three connection points between the vibration-damping bracket 4 and the device body 300, and the three connection points can be roughly located in the same plane, that is, the mounting plane.

[0041] The elastic center b of the vibration-damping bracket 4 and the projection of the total mass center c of the sensor 5 and the vibration-damping bracket 4 on the installation plane of the vibration-damping bracket 4 are roughly coincident, and the support center a of the vibration-damping bracket 4 and the total mass center c of the sensor 5 and the vibration-damping bracket 4 are roughly located in the same horizontal plane, thereby realizing the optimal design of the arrangement position of each vibration absorber 1 in the vibration-damping bracket 4. Among them, the installation plane can be parallel to the horizontal plane.

[0042] It should be noted that simulation methods can be used to determine whether the elastic center b of the vibration-damping bracket 4 coincides with the projection of the total center of mass c of the sensor 5 and the vibration-damping bracket 4 on the installation plane of the vibration-damping bracket 4, and whether the support center a of the vibration-damping bracket 4 and the total center of mass c of the sensor 5 and the vibration-damping bracket 4 are located in the same horizontal plane.

[0043] Research has shown that in a single degree of freedom direction, the curve diagram of the change of the transmissibility β with the frequency ratio λ under different damping ratios ξ is as follows: Figure 4 , where the transmissibility β is the ratio of the system’s displacement response amplitude to the input displacement excitation amplitude, and the frequency ratio λ is the ratio of the excitation frequency to the system’s natural frequency, given by Figure 4 It can be seen that when λ=1, β will greatly exceed 1, and resonance will occur. Therefore, when designing products, it is necessary to avoid the system's natural frequency being equal to the excitation frequency. When λ is less than 1, the vibration reduction purpose can be achieved. As λ increases, the transmission rate β becomes smaller and smaller, and the vibration reduction effect becomes better and better. Therefore, in each degree of freedom direction, the ratio λ of the excitation frequency to the natural frequency of the system can be selected to be greater than Of course, the ratio of the excitation frequency to the system natural frequency λ should not be too large. Figure 4 It can be seen that when λ>3, the vibration reduction effect increases slowly. Therefore, in each degree of freedom direction, the ratio λ of the excitation frequency to the system natural frequency can be selected to be less than or equal to 3. That is, in each degree of freedom direction, the ratio λ of the excitation frequency to the system natural frequency can be greater than And less than or equal to 3.

[0044] Specifically, the vibration-damping bracket 4 can satisfy the following requirements: in each degree of freedom direction, the ratio λ1 of the excitation frequency to the natural frequency of the system can be greater than and is less than or equal to 3. For example, in each degree of freedom, the ratio of the excitation frequency to the system natural frequency λ1 can be 1.5, 1.7, 2, 2.5, 3, etc., there is no limitation.

[0045] Usually, in each degree of freedom direction, the excitation frequency can be evaluated by experimental data. In order to make the ratio of the excitation frequency to the natural frequency of the system in each degree of freedom direction greater than λ1 and is less than or equal to 3, it can be achieved by changing the natural frequency of the system. The natural frequency of the system can correspond to the natural frequency of the sensor assembly 100. The change of the natural frequency of the system can be achieved by changing the vibration-damping bracket 4. For example, the natural frequency of the system can be changed by changing the stiffness, structure, geometric distribution, etc. of the vibration-damping bracket 4.

[0046] It should be noted that in each degree of freedom direction, the ratio λ1 of the excitation frequency to the system natural frequency can be equal, partially equal, or completely unequal, and can be flexibly adjusted according to actual conditions during design.

[0047] Optionally, when the ratio λ1 of the excitation frequency to the system natural frequency is not completely equal in each degree of freedom direction, the design can be performed based on the installation position of the vibration-damping bracket 4, etc. For example, when the vibration-damping bracket 4 is used to be installed on the device body 300 along the first linear degree of freedom direction, the vibration-damping bracket 4 can satisfy: the vibration-damping performance along the first linear degree of freedom direction is better than the vibration-damping performance in other degrees of freedom directions. Specifically, it can be reflected as follows: along the first linear degree of freedom direction, the ratio of the excitation frequency to the system natural frequency is λ11, while along the other degrees of freedom directions, the ratio of the excitation frequency to the system natural frequency is λ1n, λ11>λ1n and For example, if the vibration-damping bracket 4 is used to be installed on the device body 300 along the vertical direction, the vibration-damping bracket 4 can satisfy: the vibration-damping performance along the vertical direction is better than the vibration-damping performance in the directions of other degrees of freedom.

[0048] It should be noted that, during the design, the damping ratio ξ of the vibration-damping bracket 4 can also be reasonably selected. Figure 4 It can be seen that when When the damping ratio ξ increases, the vibration transmission rate β becomes larger, and the vibration reduction effect becomes worse; when the damping ratio ξ is small and crosses the resonance zone, a large vibration will be generated. Therefore, the design of the damping ratio ξ of the vibration reduction bracket 4 can take into account both the amplification factor at resonance and the satisfactory vibration reduction effect.

[0049] Next, see Figures 5 to 10 , the vibration-damping bracket 4 is described in detail.

[0050] See also Figure 5 and Figure 6 The vibration-damping bracket 4 includes a plurality of vibration dampers 1, a first mounting seat 2 and a second mounting seat 3. The vibration damper 1 is located between the first mounting seat 2 and the second mounting seat 3 and connects the first mounting seat 2 and the second mounting seat 3. One of the first mounting seat 2 and the second mounting seat 3 is connected to the sensor 5, and the other is connected to the device body 300, so that the vibration-damping bracket 4 can attenuate the vibration transmission between the sensor 5 and the device body 300.

[0051] The vibration-damping bracket 4 can be selected to include any number of more than three vibration absorbers 1 according to actual needs, and the distribution positions of any number of more than three vibration absorbers 1 can be flexibly designed according to actual needs to achieve different vibration reduction effects and adapt to more scenarios. For example, the vibration-damping bracket 4 can include three, four, five, six, and so on vibration absorbers 1. Since when the external excitation frequency is large, if the number of vibration absorbers 1 is large, when the device body 300 is deformed, some vibration absorbers 1 may be misplaced, causing the vibration absorber 1, the first mounting seat 2, and the second mounting seat 3 to be damaged due to excessive force. Therefore, the number of vibration absorbers 1 included in the vibration-damping bracket 4 is preferably three or four. Among them, when the vibration-damping bracket 4 includes three vibration absorbers 1, it is not easily affected by the deformation of the device body 300, and the natural frequency of the system is low, and the effect of anti-torsion vibration is good; when the vibration-damping bracket 4 includes four vibration absorbers 1, it has good stability and can overcome a large torque reaction force. Therefore, in actual manufacturing, the vibration-damping bracket 4 can be selected to include three vibration absorbers 1 or four vibration absorbers 1 according to specific circumstances. It can be understood that the number of the specific shock absorbers 1 is related to the stiffness of the shock absorber and the weight of the sensor carried by the shock absorber.

[0052] The shock absorber 1 and at least one of the first mounting seat 2 and the second mounting seat 3 may be detachably connected to facilitate the addition, removal, disassembly and replacement of the shock absorber 1. The detachable connection may be any detachable connection method such as screw connection, which is not limited thereto.

[0053] The following will take the example that the vibration-damping bracket 4 includes four vibration absorbers 1 for detailed description.

[0054] See also Figure 7 The four shock absorbers 1 of the shock absorber bracket 4 can be respectively recorded as the first shock absorber 1e, the second shock absorber 1f, the third shock absorber 1g and the fourth shock absorber 1h. The first shock absorber 1e, the second shock absorber 1f, the third shock absorber 1g and the fourth shock absorber 1h can be arranged corresponding to the four vertices of the rectangle respectively. The line connecting the first shock absorber 1e and the second shock absorber 1f can correspond to the first side l1 of the rectangle. The line connecting the third shock absorber 1g and the fourth shock absorber 1h can correspond to the second side l2 of the rectangle. The second side l2 and the first side l1 are two pairs of sides of the rectangle respectively.

[0055] The first shock absorber 1e and the second shock absorber 1f, and the third shock absorber 1g and the fourth shock absorber 1h are symmetrical about the first plane, and the first shock absorber 1e and the third shock absorber 1g, and the second shock absorber 1f and the fourth shock absorber 1h are symmetrical about the second plane. Among them, the first plane is a vertical plane passing through the total center of mass c of the sensor 5 and the shock absorber bracket 4 and perpendicular to the first side l1, and the second plane is a vertical plane passing through the geometric center of gravity d of the shock absorber bracket 4 and parallel to the first side l1. By rationally designing the layout positions of the four shock absorbers 1 and the shock absorber bracket 4, it is helpful to simplify the subsequent design difficulty of the decoupling design in each degree of freedom direction.

[0056] Optionally, the support centers of the first shock absorber 1e, the second shock absorber 1f, the third shock absorber 1g and the fourth shock absorber 1h are all located in the same horizontal plane with the total center of mass c of the sensor 5 and the shock absorbing bracket 4, thereby achieving that the support center a of the shock absorbing bracket 4 is located in the same horizontal plane with the total center of mass c of the sensor 5 and the shock absorbing bracket 4.

[0057] Optionally, along the same degree of freedom, the ratio of the stiffness of the first shock absorber 1e to the stiffness of the third shock absorber 1g is a first ratio, the ratio of the stiffness of the second shock absorber 1f to the stiffness of the fourth shock absorber 1h is a second ratio, and the first ratio is equal to the second ratio. For example, along the first linear degree of freedom, the stiffness of the first shock absorber 1e is p1, the stiffness of the third shock absorber 1g is p3, along the first linear degree of freedom, the stiffness of the second shock absorber 1f is p2, and the stiffness of the fourth shock absorber 1h is p4, then along the first linear degree of freedom, the ratio of the stiffness p1 of the first shock absorber 1e to the stiffness p3 of the third shock absorber 1g, p1 / p3, is equal to the ratio of the stiffness p2 of the second shock absorber 1f to the stiffness p4 of the fourth shock absorber 1h, p2 / p4. For another example, along the second linear degree of freedom direction, the stiffness of the first shock absorber 1e is q1, the stiffness of the third shock absorber 1g is q3, along the second linear degree of freedom direction, the stiffness of the second shock absorber 1f is q2, and the stiffness of the fourth shock absorber 1h is q4. Then, along the second linear degree of freedom direction, the ratio q1 / q3 of the stiffness q1 of the first shock absorber 1e to the stiffness q3 of the third shock absorber 1g is equal to the ratio q2 / q4 of the stiffness q2 of the second shock absorber 1f to the stiffness q4 of the fourth shock absorber 1h.

[0058] Optionally, along the same degree of freedom, the stiffness of the first shock absorber 1e is equal to the stiffness of the second shock absorber 1f, and the stiffness of the third shock absorber 1g is equal to the stiffness of the fourth shock absorber 1h, so as to achieve the vibration solution of the shock absorber bracket 4 in the six degrees of freedom. For example, along the first linear degree of freedom, the stiffness p1 of the first shock absorber 1e is equal to the stiffness p3 of the third shock absorber 1g, and the stiffness p2 of the second shock absorber 1f is equal to the stiffness p4 of the fourth shock absorber 1h. For another example, along the second linear degree of freedom, the stiffness q1 of the first shock absorber 1e is equal to the stiffness q3 of the third shock absorber 1g, and the stiffness q2 of the second shock absorber 1f is equal to the stiffness q4 of the fourth shock absorber 1h.

[0059] Among them, the stiffness of the shock absorber 1 will affect the natural frequency of the system. In each degree of freedom direction, the stiffness of the first shock absorber 1e is designed to be equal to the stiffness of the second shock absorber 1f, and the stiffness of the third shock absorber 1g is designed to be equal to the stiffness of the fourth shock absorber 1h, which is conducive to simplifying the design difficulty of the vibration-damping bracket 4 and reducing the design cost.

[0060] It should be noted that the geometrical center of gravity d of the vibration-damping bracket 4 may or may not coincide with the total center of mass c of the sensor 5 and the vibration-damping bracket 4. Specifically, if, as described above, each vibration absorber 1 is distributed in a regular shape, along the same degree of freedom direction, the ratio of the stiffness of the first vibration absorber 1e to the stiffness of the third vibration absorber 1g is a first ratio, the ratio of the stiffness of the second vibration absorber 1f to the stiffness of the fourth vibration absorber 1h is a second ratio, and the first ratio is equal to the second ratio. At this time, the geometrical center of gravity d of the vibration-damping bracket 4 coincides with the elastic center b of the vibration-damping bracket 4, and the elastic center b of the vibration-damping bracket 4 roughly coincides with the projection of the total center of mass c of the sensor 5 and the vibration-damping bracket 4 on the installation plane of the vibration-damping bracket 4. Then, it can be achieved that the geometrical center of gravity d of the vibration-damping bracket 4 roughly coincides with the projection of the total center of mass c of the sensor 5 and the vibration-damping bracket 4 on the installation plane of the vibration-damping bracket 4.

[0061] If the shock absorbers 1 are distributed in irregular shapes, the stiffness of the shock absorbers 1 can be designed to be the same. The same stiffness of the shock absorbers 1 can make the elastic center b of the shock absorber bracket 4 the center of gravity of the geometric shape of the connecting line of the shock absorbers 1, so that the geometric center of gravity d of the shock absorber bracket 4 coincides with the elastic center b of the shock absorber bracket 4, and then the geometric center of gravity d of the shock absorber bracket 4 coincides with the projection of the total center of mass c of the sensor 5 and the shock absorber bracket 4 on the installation plane of the shock absorber bracket 4, thereby simplifying the design difficulty.

[0062] It should be noted that the geometric center of gravity d of the vibration-damping bracket 4 is different from the geometric center of the vibration-damping bracket 4. If each vibration absorber 1 is distributed in a regular shape (such as an equilateral triangle, a square, etc.), the geometric center of gravity d of the vibration-damping bracket 4 coincides with the geometric center of the vibration-damping bracket 4. If each vibration absorber 1 is distributed in an irregular shape, the geometric center of gravity d of the vibration-damping bracket 4 no longer coincides with the geometric center of the vibration-damping bracket 4. Specifically, if the vibration-damping bracket 4 includes three vibration absorbers 1, the geometric center of gravity d of the vibration-damping bracket 4 may be the intersection of the three centers of the triangle formed by the connecting lines of the three vibration absorbers 1.

[0063] Optionally, the vibration dampers 1 in the vibration damping bracket 4 may be substantially the same. For example, the structures and manufacturing materials of the vibration dampers 1 in the vibration damping bracket 4 may be the same.

[0064] The vibration reduction bracket 4 of the embodiment of the present application reduces vibration of the sensor 5 without affecting the internal parameters between the optical devices in the sensor 5 due to the introduction of a vibration isolation link.

[0065] Next, see Figures 8 to 10 , the shock absorber 1 is described in detail.

[0066] The shock absorber 1 includes a shock absorber and an adjusting member, and the adjusting member is connected to the shock absorber and can adjust the stiffness of the shock absorber. The stiffness of the shock absorber 1 included in the shock absorber bracket 4 can be adjusted to adapt to more usage scenarios. The number of shock absorbers 1 included in the shock absorber bracket 4, the distribution position of the shock absorbers 1 on the shock absorber bracket 4, etc. can also be flexibly adjusted. Therefore, the shock absorber bracket 4 of the embodiment of the present application has a wider range of uses.

[0067] See also Fig. 9 and Fig.10 The vibration-damping member may include a vibration-damping pad 10, and the adjusting member may include a first adjusting member 20, wherein the first adjusting member 20 is connected to the vibration-damping pad 10 and can adjust the stiffness of the vibration-damping pad 10. The vibration-damping pad 10 is an elastic member and can achieve a vibration-damping effect; the vibration-damping pad 10 can be made of elastic materials such as rubber, which is not limited thereto.

[0068] The vibration damping pad 10 has a first end face 11 and a second end face 12 opposite to the first end face 11 along a first direction x. The vibration damping pad 10 is formed with a mounting hole 15 penetrating the first end face 11 and the second end face 12. The first adjusting member 20 includes a cover plate 21, a first mounting plate 22 and a first connecting member 23. The cover plate 21 is located on the side where the first end face 11 of the vibration damping pad 10 is located. The first mounting plate 22 is located on the side where the second end face 12 of the vibration damping pad 10 is located. At least a portion of the first connecting member 23 is located in the mounting hole 15 and connects the cover plate 21 and the first mounting plate 22. The first connecting member 23 is adjustably connected to at least one of the cover plate 21 and the first mounting plate 22 so that the distance between the cover plate 21 and the first mounting plate 22 is adjustable. The cover plate 21 and the first mounting plate 22 are respectively located on the side where the first end face 11 and the second end face 12 are located. In this way, the adjustable spacing between the cover plate 21 and the first mounting plate 22 can achieve the adjustable axial pressure degree of the vibration damping pad 10, and the adjustable stiffness of the vibration damping pad 10, so that the vibration damper 1 can be adapted to more usage scenarios. That is, in the embodiment of the present application, only the first connecting member 23 and at least one of the cover plate 21 and the first mounting plate 22 are designed to be adjustable, so that the stiffness of the vibration damping pad 10 can be adjusted, so that the vibration damper 1 can be adapted to more usage scenarios, the structure of the vibration damper 1 is simple, and the stiffness of the vibration damping pad 10 is easy to adjust. Among them, the axial direction of the vibration damping pad 10 is parallel to the first direction x.

[0069] Since the cover plate 21 and the first mounting plate 22 are respectively located on the side where the first end face 11 and the second end face 12 are located, when the first connecting member 23 is relatively adjusted with at least one of the cover plate 21 and the first mounting plate 22, the axial direction of the vibration damping pad 10 will be pressed by the cover plate 21 and the first mounting plate 22 instead of directly contacting the first connecting member 23. In this way, when the first connecting member 23 is adjusted and moved relative to at least one of the cover plate 21 and the first mounting plate 22, the first connecting member 23 will not wear the first end face 11 and the second end face 12 of the vibration damping pad 10, thereby extending the service life of the vibration damping pad 10.

[0070] It should be noted that the first connecting member 23 can be directly arranged in the mounting hole 15 of the vibration damping pad 10, and a spacer can also be arranged between the first connecting member 23 and the hole wall of the mounting hole 15 of the vibration damping pad 10 to prevent the first connecting member 23 from wearing the hole wall of the mounting hole 15 when it moves relative to at least one of the cover plate 21 and the first mounting plate 22. Specifically, the first adjusting member 20 also includes a first sleeve 24 located in the mounting hole 15 and connected to the cover plate 21 and / or a second sleeve 25 located in the mounting hole 15 and connected to the first mounting plate 22. The first connecting member 23 can be sleeved in the first sleeve 24 and the second sleeve 25, and can be adjustably connected to at least one of the first sleeve 24 and the second sleeve 25.

[0071] It can be understood that the first adjusting member 20 includes the first sleeve 24 and / or the second sleeve 25, and the first adjusting member 20 may include the first sleeve 24 of the first sleeve 24 and the second sleeve 25, in which case the first connecting member 23 is adjustably connected to the first sleeve 24. The first adjusting member 20 includes the first sleeve 24 and / or the second sleeve 25, and the first adjusting member 20 may include the second sleeve 25 of the first sleeve 24 and the second sleeve 25, in which case the first connecting member 23 is adjustably connected to the second sleeve 25. The first adjusting member 20 includes the first sleeve 24 and / or the second sleeve 25, and the first adjusting member 20 may include the first sleeve 24 and the second sleeve 25, in which case the first connecting member 23 is adjustably connected to at least one of the first sleeve 24 and the second sleeve 25.

[0072] It should be noted that when the first adjustment member 20 includes a first sleeve 24 and a second sleeve 25 and the first connecting member 23 is adjustably connected to one of the first sleeve 24 and the second sleeve 25, the first connecting member 23 and the other of the first sleeve 24 and the second sleeve 25 can be fixedly connected, etc., and there is no limitation on this. If the first connecting member 23 is adjustably connected to the first sleeve 24 and the second sleeve 25, the adjustment of the first connecting member 23 relative to the first sleeve 24 and the second sleeve 25 can be performed synchronously to speed up the stiffness adjustment speed of the vibration damping pad 10; if the first connecting member 23 is adjustably connected to the first sleeve 24 and the second sleeve 25, when adjusting the stiffness of the vibration damping pad 10, the first connecting member 23 and the first sleeve 24 or the second sleeve 25 can also be selectively adjusted, and the selection can be flexibly made in combination with actual needs, which has a wider applicability.

[0073] The above-mentioned adjustable connection can be a snap connection, a threaded connection, etc., which is not limited. In the embodiment of the present application, the adjustable connection is a threaded connection to make the adjustment easy to operate.

[0074] In an exemplary solution, the first connecting member 23 includes a first screw, the cover plate 21 is provided with a first through hole connected to the inner cavity of the first sleeve 24, the head of the first screw is located at the end of the cover plate 21 away from the vibration damping pad 10, the stem of the first screw passes through the first through hole, the inner cavity of the first sleeve 24 and the inner cavity of the second sleeve 25 in sequence, and the stem of the first screw is at least threadedly connected with the second sleeve 25. In this way, the first screw and the second sleeve 25 can be tightened by rotating the first screw in one direction, and the distance between the first sleeve 24 and the second sleeve 25 can be shortened under the push of the head of the first screw, and then the distance between the cover plate 21 and the first mounting plate 22 can be shortened, so that the stiffness of the vibration damping pad 10 can be adjusted; the first screw and the second sleeve 25 can be loosened by rotating the first screw in another direction, and the pressure on the vibration damping pad 10 is reduced so that it can be stretched out, and the stiffness of the vibration damping pad 10 can also be adjusted. That is, in actual use, the vibration damping pad 10 can be adjusted to a desired stiffness by rotating the first screw to tighten or loosen it relative to the second sleeve 25 .

[0075] The above-mentioned arrangement of the head of the first screw on the side of the cover plate 21 away from the vibration damping pad 10 can avoid the head of the first screw from obstructing the connection between the first mounting plate 22 and the first mounting seat 2, compared with the arrangement of the head of the first screw on the side of the first mounting plate 22 away from the vibration damping pad 10.

[0076] The first sleeve 24 and the cover plate 21 may be detachably connected or may be an integrally formed structure. In the embodiment of the present application, the first sleeve 24 and the cover plate 21 are an integrally formed structure to simplify the assembly process of the first adjustment member 20 and improve the assembly efficiency of the shock absorber 1. The second sleeve 25 and the first mounting plate 22 may be detachably connected or may be an integrally formed structure. In the embodiment of the present application, the second sleeve 25 and the first mounting plate 22 are an integrally formed structure to simplify the assembly process of the first adjustment member 20 and improve the assembly efficiency of the shock absorber 1.

[0077] It should be noted that in order to improve the vibration reduction effect of the vibration damping pad 10, the outer wall surface of the first sleeve 24 and the inner wall surface of the mounting hole 15 of the vibration damping pad 10 can be fitted or even pressed, the outer wall surface of the second sleeve 25 and the inner wall surface of the mounting hole 15 of the vibration damping pad 10 can be fitted or even pressed, the cover plate 21 and the first end surface 11 of the vibration damping pad 10 can be fitted or even pressed, and the first mounting plate 22 and the second end surface 12 of the vibration damping pad 10 can be fitted or even pressed.

[0078] It should be noted that the vibration-damping bracket 4 can be directly connected to the first mounting seat 2 and the second mounting seat 3 through the cover plate 21 of the first adjusting member 20 and the first mounting plate 22, or can be connected to the first mounting seat 2 and the second mounting seat 3 through other structural members. Fig. 9 and Fig.10 The vibration-damping bracket 4 further includes a mounting member 30, which is connected to the vibration-damping pad 10. The mounting member 30 includes a second mounting plate 31, which is located on the side where the first end surface 11 of the vibration-damping pad 10 is located, and when viewed along the first direction x, the second mounting plate 31 is located on the periphery of the cover plate 21. The first mounting plate 22 is connected to the first mounting seat 2, and the second mounting plate 31 is connected to the second mounting seat 3. The first mounting seat 2 can be connected to the device body 300, and the second mounting seat 3 can be connected to the sensor 5.

[0079] Among them, the first mounting plate 22 and the second mounting plate 31 can be rigid parts to improve the connection reliability between the shock absorber 1 and the first mounting seat 2 and the second mounting seat 3. In the embodiment of the present application, the first mounting plate 22 and the second mounting plate 31 connecting the first mounting seat 2 and the second mounting seat 3 are both arranged in the shock absorber 1, so that the shock absorber 1 can be constructed as a modular structure, and the disassembly and assembly are more flexible and convenient. The second mounting plate 31 is located on the side where the first end face 11 of the vibration damping pad 10 is located, that is, the second mounting plate 31 is located on the end side of the vibration damping pad 10. Compared with locating the second mounting plate 31 in the middle of the vibration damping pad 10, it can avoid the vibration damping pad 10 from obstructing the connection between the second mounting plate 31 and the second mounting seat 3.

[0080] The vibration damping pad 10 also has an outer peripheral surface 13 connected between the first end surface 11 and the second end surface 12, and a portion of the outer peripheral surface 13 is recessed inwardly, so that the vibration damping pad 10 forms a recessed portion 14. The mounting member 30 also includes a bending member 32. The bending member 32 is bent relative to the second mounting plate 31, and one end of the bending member 32 is connected to the second mounting plate 31, and the other end is embedded in the recessed portion 14. Among them, the recessed portion 14 is located between the first end surface 11 and the second end surface 12, and the bending plate is embedded in the recessed portion 14, so that the vibration can be attenuated when it is transmitted to the recessed portion 14 located between the first end surface 11 and the second end surface 12 on the vibration damping pad 10, thereby achieving vibration reduction.

[0081] When the shock absorber 1 is in use, the first mounting plate 22 of the first adjusting member 20 and the second mounting plate 31 of the mounting member 30 are connected to the first mounting seat 2 and the second mounting seat 3, respectively. Since the first adjusting member 20 and the mounting member 30 are at least partially embedded in the vibration damping pad 10, the vibration damping pad 10 can attenuate the impact or vibration from any structural member in multiple degrees of freedom directions (such as the radial and axial directions of the vibration damping pad 10) to achieve vibration reduction. Moreover, the first adjusting member 20 and the mounting member 30 are at least partially embedded in the vibration damping pad 10, which can increase the contact area between the first adjusting member 20, the mounting member 30 and the vibration damping pad 10, improve the vibration damping effect of the vibration damping pad 10, and simplify the connection process between the first adjusting member 20, the mounting member 30 and the vibration damping pad 10 without adding auxiliary structural connections.

[0082] The bending form of the bending member 32 relative to the second mounting plate 31 can be varied, as long as the bending member 32 can be embedded in the recessed portion 14 after being bent.

[0083] In the embodiment of the present application, the bending member 32 includes a first bending plate 321 and a second bending plate 322. The first bending plate 321 is bent relative to the second mounting plate 31, and one end is connected to the second mounting plate 31, and the other end extends along the first direction x toward the direction close to the recessed portion 14. The second bending plate 322 is bent relative to the first bending plate 321, and one end is connected to an end of the first bending plate 321 away from the second mounting plate 31, and the other end is embedded in the recessed portion 14. At this time, the bending member 32 includes the first bending plate 321 extending along the first direction x, which can make the bending of the bending member 32 relatively regular and not easy to cause obstruction to the vibration damping pad 10.

[0084] The recessed portion 14 is recessed along the second direction y, and the other end of the second bent plate 322 is embedded in the recessed portion 14 along the second direction y, and the second direction y is perpendicular to the first direction x. That is, the bending member 32 includes a bending plate bent in two perpendicular directions, which can minimize the obstruction of the bending member 32 to the vibration damping pad 10.

[0085] The first bending plate 321 may be in a strip structure extending along the first direction x, or in a ring structure extending along the first direction x, that is, the first bending plate 321 is arranged around the first direction x, so that the structural strength of the first adjusting member 20 is better. Further, when viewed along the first direction x, the first bending plate 321 is spaced apart from the outer peripheral surface 13, so as to further reduce the obstruction of the first bending plate 321 to the vibration damping pad 10.

[0086] Among them, the recessed portion 14 can be a strip-shaped hole extending along the second direction y. In this case, the second bending plate 322 is a strip-shaped structure extending along the second direction y, and the second direction y is a certain direction perpendicular to the first direction x. The recessed portion 14 can also be an annular structure extending along the second direction y. In this case, the second bending plate 322 can be an annular structure extending along the second direction y. In this case, the second direction y is a circumferential direction perpendicular to the first direction x. Of course, the second bending plate 322 can also be a strip-shaped structure extending along the second direction y. In the embodiment of the present application, that is, the recessed portion 14 is an annular structure extending along the second direction y, and the second bending plate 322 is an annular structure extending along the second direction y, that is, the recessed portion 14 is arranged around the first direction x, and the second bending plate 322 is arranged around the first direction x, so that there is sufficient contact area between the second bending plate 322 and the vibration damping pad 10, and the vibration damping effect and connection effect are better.

[0087] It should be noted that the second mounting plate 31 and the first bending plate 321, and the first bending plate 321 and the second bending plate 322 are connected in a smooth transition to avoid stress concentration, which may cause the mounting member 30 to break, etc. The second mounting plate 31 and the bending member 32 may be detachably connected or may be an integrally formed structure. In the embodiment of the present application, the second mounting plate 31 and the bending member 32 are an integrally formed structure to simplify the assembly process of the mounting member 30 and improve the assembly efficiency of the shock absorber 1.

[0088] It should be noted that in order to improve the vibration reduction effect of the vibration reduction pad 10, the two end surfaces of the second bending plate 322 distributed along the first direction x can fit into or even press against the inner wall surface of the recessed portion 14, and the second bending plate 322 is away from the first bending plate 321 to avoid fitting into or even pressing against the inner wall surface of the recessed portion 14.

[0089] See also Figures 8 to 10 The vibration-damping member may further include a vibration-damping sleeve 40, which is arranged around the first direction x, and is located at the periphery of the vibration-damping pad 10 when viewed along the first direction x, and the two ends of the vibration-damping sleeve 40 are respectively connected to the first adjustment member 20 and the mounting member 30. The vibration-damping sleeve 40 is an elastic member that can achieve a vibration-damping effect; the vibration-damping sleeve 40 may be made of elastic materials such as rubber, which is not limited thereto.

[0090] That is, the setting of the vibration-damping sleeve 40 can, on the one hand, enhance the vibration-damping effect of the vibration absorber 1 , and on the other hand, prevent impurities such as dust and stones from passing through between the first adjusting member 20 and the mounting member 30 and contacting the vibration-damping pad 10 , thereby ensuring the vibration-damping performance of the vibration-damping pad 10 .

[0091] The two ends of the vibration-damping sleeve 40 are respectively connected to the first adjusting member 20 and the mounting member 30, and the two ends of the vibration-damping sleeve 40 are respectively connected to the first mounting plate 22 and the second mounting plate 31. For example, the vibration-damping sleeve 40 is connected to the first mounting plate 22 and the second mounting plate 31 by bonding or the like.

[0092] In another optional embodiment of the present application, the adjusting member further includes a second adjusting member 50 corresponding to the vibration damping sleeve 40, and the vibration damping sleeve 40 is connected to the first adjusting member 20 and the mounting member 30 via the second adjusting member 50, so that the stiffness of the vibration damping sleeve 40 is adjustable.

[0093] Specifically, the second adjusting member 50 includes a first pressing plate 51 and a second connecting member 52. One end of the vibration damping sleeve 40 is clamped between the first pressing plate 51 and the first mounting plate 22. The second connecting member 52 connects the first pressing plate 51 and the first mounting plate 22. The second connecting member 52 is adjustably connected to at least one of the first pressing plate 51 and the first mounting plate 22 so that the distance between the first pressing plate 51 and the first mounting plate 22 is adjustable.

[0094] It should be noted that, in order to improve the clamping reliability of the vibration-damping sleeve 40 between the first pressing plate 51 and the first mounting plate 22, a first bulged portion 41 is provided at the position where the vibration-damping sleeve 40 is clamped between the first pressing plate 51 and the first mounting plate 22, and the first bulged portion 41 is raised relative to the vibration-damping sleeve 40. The provision of the first bulged portion 41 can make the position where the vibration-damping sleeve 40 is clamped between the first pressing plate 51 and the first mounting plate 22 larger than the position where the vibration-damping sleeve 40 extends out from between the first pressing plate 51 and the first mounting plate 22, so as to prevent the vibration-damping sleeve 40 from being pulled out from between the first pressing plate 51 and the first mounting plate 22.

[0095] The second adjusting member 50 also includes a second pressing plate 53 and a third connecting member 54. The other end of the vibration damping sleeve 40 is clamped between the second pressing plate 53 and the second mounting plate 31. The third connecting member 54 connects the second pressing plate 53 and the second mounting plate 31. The third connecting member 54 is adjustably connected to at least one of the second pressing plate 53 and the second mounting plate 31 so that the distance between the second pressing plate 53 and the second mounting plate 31 is adjustable.

[0096] It should be noted that, in order to improve the connection reliability of the vibration-damping sleeve 40 between the second pressing plate 53 and the second mounting plate 31, the portion where the vibration-damping sleeve 40 is clamped between the second pressing plate 53 and the second mounting plate 31 is provided with a second bulged portion 42, and the second bulged portion 42 is raised relative to the vibration-damping sleeve 40. The provision of the second bulged portion 42 can make the portion where the vibration-damping sleeve 40 is clamped between the second pressing plate 53 and the second mounting plate 31 larger than the portion where the vibration-damping sleeve 40 extends out from between the second pressing plate 53 and the second mounting plate 31, so as to prevent the vibration-damping sleeve 40 from being pulled out from between the second pressing plate 53 and the second mounting plate 31.

[0097] The second connecting member 52 is adjustablely connected to at least one of the first pressing plate 51 and the first mounting plate 22, and the third connecting member 54 is adjustablely connected to at least one of the second pressing plate 53 and the second mounting plate 31. The adjustable connection can be a snap connection, a threaded connection, etc., which is not limited to this.

[0098] The second connecting member 52 includes a second screw, the first pressing plate 51 is provided with a second through hole, the first mounting plate 22 is provided with a first threaded hole, the head of the second screw is located at the end of the first pressing plate 51 away from the first mounting plate 22, the stem of the second screw passes through the second through hole and the first threaded hole in sequence, and the stem of the second screw is at least threadedly connected with the first threaded hole. In this way, the second screw can be tightened with the first mounting plate 22 by rotating the second screw in one direction, and the distance between the first pressing plate 51 and the first mounting plate 22 can be shortened under the push of the head of the second screw, thereby achieving the adjustable stiffness of the portion of the vibration damping sleeve 40 located between the first pressing plate 51 and the first mounting plate 22; the second screw can be loosened with the first mounting plate 22 by rotating the second screw in another direction, the pressure on the vibration damping sleeve 40 is reduced so that it can be stretched out, and the adjustable stiffness of the portion of the vibration damping sleeve 40 located between the first pressing plate 51 and the first mounting plate 22 can also be achieved. That is, in actual use, by rotating the second screw to tighten or loosen it relative to the first mounting plate 22, the portion of the vibration-damping sleeve 40 between the first pressure plate 51 and the first mounting plate 22 can be adjusted to the required rigidity.

[0099] The above-mentioned first pressure plate 51 is located on the side of the first mounting plate 22 away from the cover plate 21, and the head of the second screw is set on the side of the first pressure plate 51 away from the first mounting plate 22. Compared with setting the head of the second screw on the side of the first mounting plate 22 away from the first pressure plate 51, it is more convenient to tighten or loosen the second screw.

[0100] It should be noted that the second connecting member 52 may include one second screw or multiple second screws. When the second connecting member 52 includes multiple second screws, the multiple second screws are evenly distributed in the circumferential direction of the vibration-damping sleeve 40. In this way, the rigidity of the portion of the vibration-damping sleeve 40 located between the first pressing plate 51 and the first mounting plate 22 can be adjusted by the multiple second screws, so that the rigidity of the portion of the vibration-damping sleeve 40 located between the first pressing plate 51 and the first mounting plate 22 is roughly evenly distributed in the circumferential direction thereof.

[0101] The third connecting member 54 includes a third screw, the second mounting plate 31 is provided with a third through hole, the second pressing plate 53 is provided with a second threaded hole, the head of the third screw is located at the end of the second mounting plate 31 away from the second pressing plate 53, the stem of the third screw passes through the third through hole and the second threaded hole in sequence, and the stem of the third screw is at least threadedly connected with the second threaded hole. In this way, the third screw can be tightened with the second pressing plate 53 by rotating the third screw in one direction, and the distance between the second mounting plate 31 and the second pressing plate 53 can be shortened under the push of the head of the third screw, thereby achieving the adjustable stiffness of the portion of the vibration damping sleeve 40 located between the second pressing plate 53 and the second mounting plate 31; the third screw can be loosened with the second pressing plate 53 by rotating the third screw in another direction, the pressure on the vibration damping sleeve 40 is reduced so that it can be stretched out, and the adjustable stiffness of the portion of the vibration damping sleeve 40 located between the second pressing plate 53 and the second mounting plate 31 can also be achieved. That is, in actual use, by rotating the third screw to tighten or loosen it relative to the second pressing plate 53, the portion of the vibration-damping sleeve 40 between the second pressing plate 53 and the second mounting plate 31 can be adjusted to the required rigidity.

[0102] The above-mentioned second pressure plate 53 is located on the side of the second mounting plate 31 close to the first mounting plate 22, and the head of the third screw is set on the side of the second mounting plate 31 away from the second pressure plate 53. Compared with setting the head of the third screw on the side of the second pressure plate 53 away from the second mounting plate 31, it is more convenient to tighten or loosen the third screw.

[0103] It should be noted that the third connecting member 54 may include one third screw or multiple third screws. When the third connecting member 54 includes multiple third screws, the multiple third screws are evenly distributed in the circumferential direction of the vibration-damping sleeve 40. In this way, the rigidity of the portion of the vibration-damping sleeve 40 located between the second pressing plate 53 and the second mounting plate 31 can be adjusted by the multiple third screws, so that the rigidity of the portion of the vibration-damping sleeve 40 located between the second pressing plate 53 and the second mounting plate 31 is roughly evenly distributed in the circumferential direction thereof.

The dustproof pad 60 can be arranged around the first direction x, which is not limited thereto.

[0105] The first mounting plate 22 is provided with a first positioning protrusion (not shown in the figure), a first positioning hole 201 (see Figure 6), the first mounting seat 2 is provided with the other of a first positioning protrusion and a first positioning hole 201, and the first positioning protrusion is located in the first positioning hole 201. The provision of the first positioning protrusion and the first positioning hole 201 can position the installation position of the shock absorber 1 on the first mounting seat 2, which is beneficial to improving the assembly efficiency of the shock absorber 1 and the first mounting seat 2, and the assembly consistency of multiple shock absorbers 1 and the first mounting seat 2. It should be noted that the first mounting plate 22 can also be provided with both a positioning protrusion and a positioning hole, such as the first mounting plate 22 is provided with a first positioning protrusion and a third positioning hole, and the first mounting seat 2 is provided with a first positioning hole 201 corresponding to the first positioning protrusion and a third positioning protrusion corresponding to the third positioning hole, and the embodiment of the present application is not limited to this.

[0107] See also Figures 11 to 13 , Fig.11 FIG. 4 shows a schematic diagram of a transmissibility curve of the sensor 5 in the direction of the first degree of freedom of movement when the sensor 5 has a vibration-damping bracket 4 and when the sensor 5 does not have a vibration-damping bracket 4. Fig.12 FIG. 4 shows a schematic diagram of a transmissibility curve of the sensor 5 in the direction of the second degree of freedom of movement when the sensor 5 has a vibration-damping bracket 4 and when the sensor 5 does not have a vibration-damping bracket 4. Fig.13 The schematic diagram of the transmissibility curve of the sensor 5 in the third degree of freedom of movement when there is a vibration-damping bracket 4 and when there is no vibration-damping bracket 4 is shown, wherein the first degree of freedom of movement direction, the second degree of freedom of movement direction and the third degree of freedom of movement direction are perpendicular to each other. Figures 11 to 13 It can be seen that the acceleration of the sensor 5 provided with the vibration reduction bracket 4 in the first, second and third degrees of freedom of movement direction is significantly reduced, which can play a more significant vibration reduction effect, and is conducive to improving the point cloud stability and service life of the sensor 5. Among them, the first degree of freedom of movement direction can be parallel to the first direction.

[0108] Moreover, it has been verified through experiments that, compared with the sensor 5 without the vibration-damping bracket 4, the maximum stress in the first degree of freedom of movement of the sensor 5 provided with the vibration-damping bracket 4 in the embodiment of the present application can be reduced from 12.34 MPa to 9.8 MPa, and the maximum stress in the second degree of freedom of movement can be reduced from 12.33 MPa to 9.866 MPa, etc. The stress on the internal structural parts of the sensor 5 is reduced, and the safety factor is higher.
