Description

Technical Field

[0001] This application relates to the field of sensing technology, and in particular to an adjustment device and a mobile device. Background Technology

[0002] Mobile devices, such as warehouse robots, are typically equipped with detection units to detect the distance between the mobile device and surrounding obstacles, ensuring that the mobile device does not collide with surrounding obstacles and making the operation of the mobile device safer.

[0003] In related technologies, the detection unit is generally connected to the mobile device through a shock-absorbing mechanism. The shock-absorbing mechanism is equipped with elastic elements, which can reduce the probability of the detection unit experiencing angular displacement or other abnormalities due to vibration. Some mobile devices also have an angle positioning component installed in their shock-absorbing mechanism. The angle positioning component has multiple adjustment screws, and the detection angle of the detection unit can be adjusted by adjusting these screws.

[0004] However, existing angle positioning components have complex structures and require adjustment of multiple adjusting screws, making adjustment inconvenient. Utility Model Content

[0005] This application provides an adjustment device and a movable device to solve the technical problem that existing angle positioning components have complex structures, require adjustment of multiple adjustment screws, and are inconvenient to adjust.

[0006] In a first aspect, this application provides an adjustment device, which includes a fixed base, a mounting plate, a support member, multiple elastic members, and an adjustment assembly. The mounting plate is spaced apart from the fixed base, and the side of the mounting plate facing away from the fixed base is used to mount a detection unit. The support member and multiple elastic members are supported between the fixed base and the mounting plate. The adjustment assembly includes at least one adjustment member that connects the fixed base and the mounting plate. Each adjustment member corresponds to one of the multiple elastic members, and the adjustment member is configured to adjust the distance between the fixed base and the mounting plate at the location of its corresponding elastic member, thereby adjusting the compression amount of the corresponding elastic member so that the mounting plate deflects with the support member as a hinge point, thereby adjusting the posture of the mounting plate relative to the fixed base.

[0007] The adjustment device provided in this application includes a fixed base and a mounting plate. The detection unit is mounted on the mounting plate, and multiple elastic elements are provided between the mounting plate and the fixed base to dampen the vibration of the mounting plate and prevent the detection unit from malfunctioning due to vibration. At least one of the multiple elastic elements is provided with a corresponding adjustment element. The distance between the fixed base and the mounting plate can be adjusted using the adjustment element to adjust the posture of the mounting plate relative to the fixed base, thereby giving the detection unit a suitable detection angle and making the adjustment process more convenient.

[0008] As an optional implementation, the fixing base and the mounting plate are arranged at intervals in the vertical direction, with the mounting plate located above the fixing base; the fixing base has a first support surface on the side facing the mounting plate, and the mounting plate has a second support surface on the side facing the fixing base, with the two ends of the elastic member abutting against the first support surface and the second support surface, respectively.

[0009] This design allows for vibration damping of the mounting plate via elastic elements, preventing damage to the detection unit due to vibration.

[0010] As an optional implementation, the adjusting member is vertically inserted between the fixed seat and the mounting plate; when the adjusting member adjusts the distance between the fixed seat and the mounting plate at the corresponding position, it can change the tilt direction and tilt angle of the second support surface relative to the first support surface.

[0011] With this configuration, the tilt direction and tilt angle of the second support surface relative to the first support surface can be adjusted by adjusting the adjustment component, ensuring that the detection unit is at a suitable detection angle.

[0012] As an optional implementation, the two ends of the support member are connected to the fixed base and the mounting plate, respectively; the two ends of the elastic member abut against the fixed base and the mounting plate, respectively; the elastic members are spaced apart on the side of the support member; and the adjusting member is correspondingly arranged with the elastic member.

[0013] This configuration allows for shock absorption of the mounting plate via support members and at least two elastic members, preventing damage to the detection unit due to vibration.

[0014] As an optional implementation, there are at least two adjusting members, and each adjusting member is provided in a one-to-one correspondence with an elastic member.

[0015] With this configuration, the distance between the fixed seat at the elastic element and the mounting plate can be adjusted using the adjusting mechanism.

[0016] As an optional implementation, at least two elastic elements are located on one side of the support member along the first direction; by adjusting the compression of the elastic elements, the adjustment member can be used as a hinge point at the end of the support member to adjust the tilt angle of the mounting plate relative to the first direction.

[0017] At least two elastic elements are spaced apart along a second direction, which is perpendicular to the first direction; by adjusting the corresponding adjusting elements, different elastic elements can have different compression amounts to adjust the tilt angle of the mounting plate relative to the second direction.

[0018] With this configuration, the detection angle of the detection unit can be adjusted along both the first and second directions using the adjustment mechanism, thereby improving the accuracy of the detection.

[0019] As an optional implementation, there are two elastic elements, and the support and the two elastic elements are arranged in a triangle between the fixed base and the mounting plate.

[0020] This setup ensures the adjustability of the detection unit's angle while minimizing the number of parts.

[0021] As an alternative implementation, in its natural state, the height of the elastic member is greater than the height of the support member.

[0022] This design allows for more room for angle adjustment, facilitating subsequent adjustment of the detection unit's angle.

[0023] As an optional implementation, the cross-sectional dimensions of the support gradually decrease from both ends to the middle of the support; and / or, the support is a solid elastomeric structure.

[0024] This design allows the support components to deform through the narrow central section, improving energy dissipation and thus enhancing the shock absorption effect.

[0025] As an optional implementation, the adjustment device also includes a countersunk screw and a fixing nut; the first end of the support member is provided with an embedded nut, the mounting plate is provided with a countersunk hole, the countersunk screw passes through the countersunk hole and is connected to the embedded nut; the second end of the support member is provided with an embedded screw, the embedded screw passes through the fixing seat, and the fixing nut is connected to the embedded screw on the side of the fixing seat away from the support member.

[0026] This design improves the stability of the connection between the support and the mounting plate and the fixed base.

[0027] As an alternative implementation, the elastic element has a through hole extending along its axial direction, and the adjusting element passes through the through hole.

[0028] This design, by inserting the adjustment element through the through hole, ensures the adjustability of the structure while making it more compact.

[0029] As an optional implementation, the adjusting component is an adjusting screw, the mounting plate has a first mounting hole, the fixing base has a second mounting hole, and the second mounting hole is provided with a press-fit nut; the adjusting screw passes through the first mounting hole, the through hole, and the second mounting hole in sequence, and is connected to the press-fit nut.

[0030] This design, through the through-connection of the adjusting screw and the rivet nut, makes the structure more stable. At the same time, the elastic element can apply preload to the mounting plate and the fixing seat. The distance between the mounting plate and the fixing seat can be adjusted simply by rotating the adjusting screw.

[0031] As an optional implementation, the adjustment device also includes a locking nut, which is located on the side of the fixed seat away from the mounting plate. The locking nut is locked to the adjustment screw and abuts against the press-fit nut.

[0032] This design, using locking nuts, can further improve the connection stability of the structure and prevent loosening.

[0033] Secondly, this application provides a mobile device, including a mobile chassis, a detection unit and the aforementioned adjustment device, wherein the adjustment device is connected to the mobile chassis, and the detection unit is disposed on the adjustment device, wherein the detection unit is at least one of radar, vision sensor, photoelectric sensor and acoustic sensor.

[0034] This application provides an adjustment device, which includes a fixed base, a mounting plate, a support member, multiple elastic members, and an adjustment assembly. The mounting plate is spaced apart from the fixed base and is used to mount a detection unit. The support member and multiple elastic members are supported between the fixed base and the mounting plate. The adjustment assembly includes at least one adjustment member connected to the fixed base and the mounting plate. Each adjustment member corresponds to one of the multiple elastic members, and the adjustment member is configured to adjust the distance between the fixed base and the mounting plate at the location of its corresponding elastic member, thereby adjusting the compression of the corresponding elastic member. This causes the mounting plate to deflect about the support member as a hinge point, adjusting the posture of the mounting plate relative to the fixed base. The adjustment device provided by this application has both shock absorption and angle adjustment functions, and the angle adjustment is simple and convenient to operate.

[0050] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0057] Mobile devices, such as warehouse robots, are typically equipped with detection units to monitor the distance between the mobile device and surrounding obstacles, ensuring that the device does not collide with these obstacles and making its operation safer. In related technologies, the detection unit is generally installed within a shock-absorbing mechanism, which connects to the mobile device. The shock-absorbing mechanism contains elastic components to reduce the probability of the detection unit experiencing angular displacement or other abnormalities due to vibration. Some mobile devices also have angle positioning components within their shock-absorbing mechanisms, which have multiple adjusting screws. Adjusting these screws allows for adjustment of the detection angle of the detection unit.

[0058] However, the existing angle positioning components have a complex structure, and adjusting the detection angle of the detection unit requires fine-tuning multiple adjusting screws, which is inconvenient.

[0059] To address the aforementioned issues, this application provides an adjustment device and a movable device. The adjustment device is mounted on the movable device, and the detection unit is mounted on the mounting plate. A support member and multiple elastic members are provided between the fixed base and the mounting plate of the adjustment device for shock absorption. Each elastic member has a corresponding adjustment member, which can adjust the distance between the fixed base and the mounting plate at the location of its corresponding elastic member, thereby adjusting the compression amount of the corresponding elastic member and adjusting the posture of the mounting plate relative to the fixed base, thus adjusting the detection angle of the detection unit. This adjustment device has a simple structure and is more convenient to adjust.

[0060] To facilitate understanding, the application scenarios of the adjustment device and mobile device provided in the embodiments of this application will be described first.

[0061] The adjustment device provided in this application is used for mobile devices. Specifically, the mobile devices can be handling robots in warehouses, autonomous vehicles, intelligent sweeping robots, etc., which require autonomous planning of mobile devices. This application does not make any specific limitations.

[0063] Reference Figures 1 to 9 As shown, this application provides an adjustment device 100 for a movable device. The adjustment device 100 includes a fixed base 110, a mounting plate 120, a support member 131, a plurality of elastic members 132, and an adjustment assembly 140. The mounting plate 120 is spaced apart from the fixed base 110 and is used to mount a detection unit 300. The plurality of elastic members 132 are supported between the fixed base 110 and the mounting plate 120. The adjustment assembly 140 includes at least one adjustment member 141, which connects the fixed base 110 and the mounting plate 120.

[0064] It should be noted that the detection unit 300 is installed on the side of the mounting plate 120 opposite to the fixed base 110. The movable device includes a movable chassis 200, the detection unit 300, and an adjustment device 100. The adjustment device 100 is connected to the movable chassis 200, and the detection unit 300 is disposed on the adjustment device 100. The fixed base 110 is used to fix the entire adjustment device 100 to the movable chassis 200. The fixed base 110 and the movable chassis 200 can be connected by bolts, snap-fit ​​connections, magnetic connections, pin connections, etc. The detection unit 300 can be at least one of a visual sensor, a photoelectric sensor, and an acoustic sensor, used to detect the position of nearby obstacles.

[0065] For example, the fixed base 110 is connected to the mobile chassis 200 by the fixed base fixing screw 113, and the detection unit 300 is connected to the mounting plate 120 by the detection unit fixing screw 310.

[0066] For example, the mobile device is a warehouse robot, the detection unit 300 is a LiDAR, and an adjustment device 100 is installed at each of the two opposite corners of the robot's chassis. Each adjustment device 100 is equipped with a LiDAR, giving the robot a large recognition area, avoiding excessive blind spots, and ensuring safety. When the warehouse robot moves between shelves, the LiDAR can identify obstacles at the edges of the aisles and in the aisles, and feed this information back to the robot's navigation system, helping the robot to adjust and plan its path in real time to avoid collisions.

[0067] In one possible implementation, each adjusting member 141 is correspondingly provided with one of a plurality of elastic members 132. The adjusting member 141 is configured to adjust the distance between the fixed seat 110 and the mounting plate 120 at the location of its corresponding elastic member 132, thereby adjusting the compression amount of the corresponding elastic member 132 so that the mounting plate 120 deflects with the support member 131 as the hinge point, thereby adjusting the posture of the mounting plate 120 relative to the fixed seat 110.

[0068] Understandably, since the fixed base 110 is rigidly connected directly to the mobile chassis 200 of the mobile device, when the mobile device moves and experiences bumps, it will cause the fixed base 110 to vibrate. A support member 131 and multiple elastic members 132 are provided between the fixed base 110 and the mounting plate 120. The support member 131 is elastic and has a certain degree of rigidity. The support member 131 and the elastic members 132 can deform and absorb vibration energy when the fixed base 110 vibrates, thereby reducing the vibration of the mounting plate 120, maintaining the stability of the detection unit 300, and preventing changes in the detection angle of the detection unit 300 on the mounting plate 120, or loosening or even damage. The support member 131 and the elastic members 132 also serve a supporting function between the fixed base 110 and the mounting plate 120. By adjusting the compression of the elastic members 132 through the adjusting member 141, the distance between certain positions between the fixed base 110 and the mounting plate 120 can be adjusted, thereby adjusting the posture of the mounting plate 120 relative to the fixed base 110.

[0069] As one possible implementation, the fixing base 110 and the mounting plate 120 are arranged vertically at intervals, with the mounting plate 120 located above the fixing base 110; the fixing base 110 has a first support surface 111 on the side facing the mounting plate 120, and the mounting plate 120 has a second support surface 121 on the side facing the fixing base 110; the two ends of the support member 131 and the elastic member 132 abut against the first support surface 111 and the second support surface 121, respectively.

[0070] It is understood that when the adjusting device 100 is fixed to the movable chassis 200, the mounting plate 120 is located above the fixed base 110, and the detection unit 300 is installed on the side of the mounting plate 120 opposite to the second support surface 121. The two ends of the support member 131 and the elastic member 132 can be glued to the fixed base 110 and the mounting plate 120, or connected by screws, or by other means.

[0071] As one possible implementation, the adjusting member 141 is vertically inserted between the fixed seat 110 and the mounting plate 120; when the adjusting member 141 adjusts the distance between the fixed seat 110 and the mounting plate 120 at the corresponding positions, it can change the tilt direction and tilt angle of the second support surface 121 relative to the first support surface 111.

[0072] It is understood that each of the multiple elastic elements 132 is provided with a corresponding adjusting element 141. The multiple elastic elements 132 and the multiple adjusting elements 141 correspond one-to-one. The distance between the mounting plate 120 and the fixed seat 110 can be adjusted by adjusting the adjusting element 141, thereby adjusting the posture of the mounting plate 120 relative to the fixed seat 110, and thus adjusting the angle of the detection unit 300 on the mounting plate 120.

[0073] It should be noted that the support member 131 and multiple elastic members 132 constitute the support assembly 130 to support the fixed base 110 and the mounting plate 120. The two ends of the support member 131 are connected to the fixed base 110 and the mounting plate 120 respectively; the two ends of the elastic members 132 abut against the fixed base 110 and the mounting plate 120 respectively; the elastic members 132 are spaced apart on the side of the support member 131; and the adjusting member 141 is correspondingly arranged with the elastic members 132.

[0074] It is understandable that the two ends of the support member 131 can be fixedly connected to the fixed base 110 and the mounting plate 120 respectively, and the two ends of the elastic member 132 can only abut against the fixed base 110 and the mounting plate 120 respectively, instead of being fixedly connected.

[0075] In some embodiments, the two ends of the elastic member 132 may also be fixedly connected only to the fixing base 110 and the mounting plate 120, respectively.

[0076] In some embodiments, there are at least two adjusting members 141, and the adjusting members 141 are arranged in a one-to-one correspondence with the elastic members 132. Each elastic member 132 can adjust the compression amount through the adjusting member 141 to adjust the distance between the fixing seat 110 and the mounting plate 120 at the location of the elastic member 132.

[0077] Reference Figures 6 to 9 , combined Figure 1 and Figure 2 As one possible implementation, at least two elastic elements 132 are located on one side of the support 131 along the first direction; by adjusting the compression of the elastic elements 132 by adjusting the adjusting element 141, the adjusting element 141 can adjust the tilt angle of the mounting plate 120 relative to the first direction with the end of the support 131 as the hinge point.

[0078] Simultaneously, at least two elastic elements 132 are spaced apart along a second direction, which is perpendicular to the first direction. By adjusting the corresponding adjusting element 141, different elastic elements 132 can have different compression amounts to adjust the tilt angle of the mounting plate 120 relative to the second direction. It should be noted that the second direction being perpendicular to the first direction does not mean that the angle between the first and second directions is exactly 90 degrees; it can be close to 90 degrees, such as 85-95 degrees, and can be adjusted according to the actual situation.

[0079] It is understandable that the main scanning direction of the detection unit 300 is the first direction. Adjusting the tilt angle of the mounting plate 120 relative to the first direction can adjust the pitch angle of the detection unit 300, and adjusting the tilt angle of the mounting plate 120 relative to the second direction can adjust the flip angle of the detection unit 300. By adjusting the pitch angle and flip angle of the detection unit 300, the detection unit 300 can have a suitable scanning angle. Its scanning surface will not be too high and affect the safety function, nor will it be too low and scan the ground, falsely triggering obstacle avoidance and affecting the normal operation of the mobile device.

[0080] In some embodiments, there are two elastic elements 132, and the support 131 and the two elastic elements 132 are arranged in a triangle between the fixing base 110 and the mounting plate 120.

[0081] It is understood that in this embodiment, the direction of the line connecting the two elastic members 132 is the second direction, and the direction of the perpendicular line between the support member 131 and the line connecting the two elastic members 132 is the first direction.

[0082] For example, by simultaneously reducing the compression of the two elastic members 132, the distance between the mounting plate 120 and the fixed seat 110 at the two elastic members 132 can be increased. Since the distance between the mounting plate 120 and the fixed seat 110 at the support member 131 remains unchanged, the mounting plate 120 can rotate with the top of the support member 131 as the hinge point, causing the scanning angle of the detection unit 300 to tilt upward relative to the horizontal direction. Figure 6 Simultaneously increasing the compression of the two elastic elements 132, so that the distance between the mounting plate 120 and the fixed seat 110 at the two elastic elements 132 is equal to the distance between the mounting plate 120 and the fixed seat 110 at the support element 131, can make the scanning angle of the detection unit 300 consistent with the horizontal direction, such as... Figure 7 ; By further increasing the compression of the two elastic elements 132, making the distance between the mounting plate 120 and the fixed seat 110 at the two elastic elements 132 smaller than the distance between the mounting plate 120 and the fixed seat 110 at the support 131, the scanning angle of the detection unit 300 can be made downward relative to the horizontal direction, such as Figure 8 .

[0083] For example, by adjusting only one of the two adjusting members 141, a difference can be created in the distance between the mounting plate 120 and the fixed seat 110 at the two elastic members 132, thereby causing the scanning surface of the detection unit 300 to have a certain rotation angle relative to the horizontal direction, such as... Figure 9 .

[0084] Understandably, during the actual adjustment process, two adjusting elements 141 can be adjusted simultaneously, and the two elastic elements 132 can have different compression amounts, so that the detection unit 300 has a pitch angle and a tilt angle.

[0085] It should be noted that in its natural state, that is, when the elastic element 132 is not compressed, the height of the elastic element 132 is greater than the height of the support element 131. This setting allows for more space for angle adjustment, which is convenient for subsequent angle adjustment of the detection unit 300.

[0086] It should be noted that the cross-sectional dimensions of the support member 131 gradually decrease from both ends to the middle of the support member 131. This waist-shaped design makes it easier for the support member 131 to generate angle changes in various directions, providing degrees of freedom for changes in roll angle and pitch angle.

[0087] Reference Figure 2 The connection method between the support member 131, the elastic member 132, the mounting plate 120, and the fixing seat 110 is described below.

[0088] As one possible implementation, the adjusting device 100 includes a countersunk screw 150 and a fixing nut 160; the first end of the support member 131 is provided with an embedded nut 1311, the mounting plate 120 is provided with a countersunk hole 123, the countersunk screw 150 passes through the countersunk hole 123 and is connected to the embedded nut 1311; the second end of the support member 131 is provided with an embedded screw 1312, the embedded screw 1312 passes through the fixing seat 110, and the fixing nut 160 is connected to the embedded screw 1312 on the side of the fixing seat 110 away from the support member 131.

[0089] The support 131 can be a solid rubber pad with a certain height. The embedded nut 1311 and the embedded screw 1312 are embedded in the first and second ends of the rubber pad, respectively. The rubber pad has an anti-rotation design. For example, the embedded position of the embedded nut 1311 and the embedded screw 1312 is a hexagonal groove, which can prevent the embedded nut 1311 and the embedded screw 1312 from slipping.

[0090] As one possible implementation, the elastic element 132 has a through hole 1321 extending along its axial direction, and the adjusting element 141 passes through the through hole 1321; the adjusting element 141 can be an adjusting screw 142, the mounting plate 120 has a first mounting hole 122, the fixing base 110 has a second mounting hole 112, and the second mounting hole 112 is provided with a press-fit nut 1121; the adjusting screw 142 passes through the first mounting hole 122, the through hole 1321, and the second mounting hole 112 in sequence, and is connected to the press-fit nut 1121.

[0091] The elastic element 132 can be a hollow cylindrical rubber pad with a certain height. The adjusting screw 142 passes through the hollow cylindrical rubber pad and connects the mounting plate 120 and the fixing seat 110. Due to the limiting effect of the adjusting screw 142 and the rivet nut 1121, the mounting plate 120 cannot move away from the fixing seat 110 at the position of the hollow cylindrical rubber pad. At the same time, since the two ends of the hollow cylindrical rubber pad abut against the first support surface 111 and the second support surface 121, the distance between the mounting plate 120 and the fixing seat 110 can be relatively fixed.

[0092] Understandably, when the adjusting screw 142 is turned to cause up and down movement, the hollow cylindrical rubber pad is more prone to deformation than the solid rubber pad. Adjusting the two screws allows for easy adjustment of the pitch and roll angles of the detection unit 300. The hollow cylindrical rubber pad expands and deforms when compressed, generating elastic force to support the mounting plate 120. Figures 7 to 9 .

[0093] As one possible implementation, the adjusting device 100 also includes a locking nut 170, which is located on the side of the fixed base 110 away from the mounting plate 120. The locking nut 170 is locked to the adjusting screw 142 and abuts against the press-fit nut 1121.

[0094] Understandably, once the angle adjustment is complete, the locking nut 170 can be tightened to make the locking nut 170 abut against the rivet nut 1121, thus achieving anti-loosening and angle stability after adjustment, and preventing angle creep after long-term operation.

[0095] This application provides an adjustment device 100, which includes a fixed base 110, a mounting plate 120, a plurality of elastic elements 132, and an adjustment assembly 140. The mounting plate 120 is spaced apart from the fixed base 110 and is used to mount a detection unit 300. The plurality of elastic elements 132 are supported between the fixed base 110 and the mounting plate 120. The adjustment assembly 140 includes at least one adjustment element 141, which connects the fixed base 110 and the mounting plate 120. Each adjustment element 141 is correspondingly arranged with one of the plurality of elastic elements 132. The adjustment element 141 is configured to adjust the distance between the fixed base 110 and the mounting plate 120 at the location of its corresponding elastic element 132, thereby adjusting the compression amount of the corresponding elastic element 132 and adjusting the posture of the mounting plate 120 relative to the fixed base 110. The adjustment device 100 provided by this application has both shock absorption and angle adjustment functions, and the angle adjustment is simple and convenient to operate.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
