Description

Technical Field

[0001] This application relates to the field of data acquisition technology, and more specifically, to a data acquisition device. Background Technology

[0002] The efficient training and performance iteration of robot models heavily rely on massive, diverse, and accurate data. Data acquisition devices, as key equipment for robot data acquisition, directly impact the effectiveness of robot training. With the help of this device, robots can accurately reproduce the fine-grained operational trajectories of human hands, simultaneously capturing the static features of target objects in three-dimensional space, such as coordinate position, posture angle, and geometric contours.

[0003] Existing data acquisition devices typically use clamps to grip objects in order to collect data. However, existing data acquisition devices are unstable when using clamps to grip objects, which can easily cause the objects to fall off. Utility Model Content

[0004] The main objective of this application is to provide a data acquisition device to solve the problem that existing data acquisition devices have poor stability when gripping objects, which can easily cause objects to fall off.

[0005] According to one aspect of this application, a data acquisition device is provided, comprising: A support member, on which an operating component is provided; A clamping mechanism is disposed on the support member, the clamping mechanism comprising two clamping components having a clamping position close to each other to clamp an object and a release position far from each other to release the object; A transmission mechanism is disposed on the support member. The transmission mechanism includes two linkage assemblies, both of which are connected to the operating component and are respectively connected to the two clamping assemblies one-to-one. The operating component is configured to move the two linkage assemblies synchronously under the action of an external force so that the two clamping assemblies are in the clamping position, and to move the two linkage assemblies synchronously when the external force is removed so that the two clamping assemblies are in the release position.

[0006] Furthermore, the operating component includes: A slider is disposed on the support and is movable along a first direction or along a second direction opposite to the first direction, and both of the linkage assemblies are connected to the slider; An operating element, which is disposed on the support and connected to the sliding element; An elastic reset component is disposed on the support member and can deform under the action of the operating member; When the operating member is driven by an external force to move the sliding member along the first direction, the elastic reset member deforms and stores elastic potential energy. At the same time, the two linkage assemblies move synchronously with the sliding member so that the two clamping assemblies are in the clamping position. When the external force is removed, the elastic reset component releases the stored elastic potential energy, causing the slider to move along the second direction, thereby driving the two linkage assemblies to move synchronously so that the two clamping assemblies are in the release position.

[0007] Further, the elastic reset component includes a first elastic reset member, which is disposed on the support member and telescopically connected between the sliding member and the support member; wherein, when the operating member is subjected to an external force, the sliding member moves along the first direction to stretch the first elastic reset member and store elastic potential energy; when the external force is removed, the sliding member moves along the second direction under the contraction of the first elastic reset member; or, The elastic reset component includes a second elastic reset member, which is rotatably disposed between the support member and the operating member. A first end of the second elastic reset member abuts against the support member, and a second end of the second elastic reset member, opposite to the first end, abuts against the operating member. When the operating member is subjected to an external force that causes the sliding member to move along the first direction, the second elastic reset member undergoes torsional deformation around its own pivot point to store elastic potential energy. When the external force is removed, the second elastic reset member releases the stored elastic potential energy and rotates in the opposite direction around its own pivot point. Under the reset action of the second elastic reset member, the operating member causes the sliding member to move along the second direction.

[0008] Furthermore, the transmission mechanism also includes two transmission components, which are connected to the two connecting rod assemblies in a one-to-one correspondence, and the end of each transmission component away from the connecting rod assembly is hinged to the sliding member; When the slider moves along the first direction or the second direction, the two transmission components respectively drive the two connecting rod assemblies to rotate in opposite directions.

[0009] Furthermore, the transmission component includes a transmission rod and a rotating part connected to the transmission rod. The end of the transmission rod away from the rotating part is hinged to the sliding member. The rotating part is rotatably mounted on the support member. The connecting rod assembly is connected to the rotating part.

[0010] Furthermore, the transmission component also includes a connecting shaft, which is disposed on the support member, and the rotating part is sleeved on the connecting shaft and can rotate around the connecting shaft; An encoder is mounted on the support member, the encoder being located at the bottom of the connecting shaft and coaxially arranged with the connecting shaft, and the encoder being drively connected to the connecting rod assembly for detecting the rotation angle of the connecting rod assembly; and / or, A retaining ring is sleeved on the connecting shaft. The retaining ring is located on the side of the rotating part near the connecting rod assembly, and the retaining ring and the connecting shaft are connected by an interference fit.

[0011] Furthermore, the operating element includes an operating lever, one end of which is rotatably connected to the support to form a rotation point, and the other end of which is connected to the sliding element; When the operating lever is subjected to an external force or the external force is removed, it can rotate around the rotation point to make the sliding member move along the first direction or the second direction.

[0012] Furthermore, one of the support member and the sliding member is provided with a guide rail extending along the first direction, and the other member is provided with a first groove adapted to the guide rail.

[0013] Furthermore, the linkage assembly includes: The first link, the first end of the first link rotates under the drive of the operating component; The second link is spaced apart from the first link, and the first end of the second link is hinged to the support member; The third link has a first end hinged to the second end of the first link, a second end hinged to the second end of the second link, and the clamping assembly is mounted on the third link.

[0014] Furthermore, each of the clamping components includes at least one type of clamping member, which is detachably mounted on the link assembly.

[0015] Furthermore, the clamping member is provided with an anti-slip portion, and the anti-slip portion has at least one protruding structure; and / or, The clamping element includes at least one of thermoplastic polyurethane clamping elements and soft rubber clamping elements.

[0016] Furthermore, a second sliding groove is provided on one of the clamping member and the connecting rod assembly, and a sliding protrusion adapted to the second sliding groove is provided on the other. The second groove has at least one first inclined surface, and the sliding protrusion has at least one second inclined surface that fits against the first inclined surface.

[0017] Furthermore, the support member has a mounting cavity and a protective member, with at least a portion of the operating components located in the mounting cavity, and the protective member covering the top of the mounting cavity; and / or, The data acquisition device further includes at least one camera, which is mounted on the support member for at least photographing the object; and / or, The support member has a mounting cavity, and the data acquisition device further includes a circuit control board disposed within the mounting cavity, with a heat-conducting element between the inner wall of the mounting cavity and the circuit control board; and / or, The support member is provided with at least one external interface; and / or, The data acquisition device also includes a base, and the support member is detachably mounted on the base.

[0018] Compared to the structure of existing data acquisition devices, this application, by setting a linkage assembly between the clamping component and the operating component, utilizes the rigid transmission characteristics of the linkage assembly to uniformly transmit the external force received by the operating component to the clamping component, avoiding offset or loss during force transmission. Simultaneously, since the two linkage assemblies are connected one-to-one with the two clamping components, the movement of the operating component is ensured to be converted into synchronous movement of the two clamping components. This ensures that both maintain a consistent displacement and velocity when approaching or moving away from the object, resulting in a symmetrical and balanced clamping effect. This reduces the imbalance of force on the object caused by uncoordinated movements of the clamping components, effectively ensuring the stability of the data acquisition device when clamping objects and reducing the risk of object detachment.

[0024] As mentioned in the background section, the efficient training and performance iteration of robot models heavily rely on massive, diverse, and accurate data. The data acquisition device, as a key component for robot data acquisition, directly impacts the training effectiveness. Existing data acquisition devices typically use grippers to grasp objects for data collection. However, existing devices suffer from poor stability when gripping objects, easily leading to object slippage. To address this, the inventors of this application have designed a novel data acquisition device that solves at least the problem of poor stability and object slippage in existing data acquisition devices. The data acquisition device of this application will be described in detail below with reference to the accompanying drawings.

[0025] See Figures 1 to 4 As shown, according to an embodiment of this application, a data acquisition device is provided, which includes a support member 10, a clamping mechanism 30, and a transmission mechanism 40.

[0026] Specifically, the support member 10 is provided with an operating component 20; the clamping mechanism 30 is provided on the support member 10, and the clamping mechanism 30 includes two clamping components 31, which have a clamping position where they are close to each other to clamp an object and a release position where they are far apart from each other to release the object; the transmission mechanism 40 is provided on the support member 10, and the transmission mechanism 40 includes two linkage assemblies 41, which are both connected to the operating component 20 and are respectively connected to the two clamping components 31 one-to-one; wherein, the operating component 20 is configured to drive the two linkage assemblies 41 to move synchronously under the action of external force so that the two clamping components 31 are in the clamping position, and to drive the two linkage assemblies 41 to move synchronously when the external force is removed so that the two clamping components 31 are in the release position.

[0027] When using the data acquisition device of this application to grip an object, the operator first aligns the device with the object so that the object is positioned between the two gripping components 31, and then applies an external force to the operating component 20 on the support 10. At this time, under the action of the external force, the operating component 20 transmits power to the two linkage components 41. The two linkage components 41 move synchronously under the drive of the operating component 20, thereby driving the two gripping components 31 to gradually move closer to each other to grip the object. During this process, since the two linkage components 41 are both connected to the operating component 20 and are respectively connected to the two gripping components 31 one-to-one, and the two linkage components 41 can move synchronously under the drive of the operating component 20, there will be no movement delay or amplitude difference in the two linkage components 41 during the power transmission process. This ensures that the two gripping components 31 always move closer to the object with a symmetrical trajectory and apply force simultaneously and evenly from both sides of the object, avoiding the object from shaking or shifting due to force imbalance, and effectively ensuring the stability of the data acquisition device gripping the object.

[0028] Once the object is stably clamped, the operator can collect data from it. After the data collection task is completed, the operator removes the external force on the operating component 20. At this time, the operating component 20 can drive the two linkage assemblies 41 to move synchronously, thereby driving the two clamping components 31 to switch from the clamping position to the release position, thus completing a complete clamping and data collection operation.

[0029] In other words, compared to the structure of existing data acquisition devices, this application, by setting a connecting rod assembly 41 between the clamping assembly 31 and the operating component 20, can utilize the rigid transmission characteristics of the connecting rod assembly 41 to uniformly transmit the external force received by the operating component 20 to the clamping assembly 31, avoiding deviation or loss during force transmission. Simultaneously, since the two connecting rod assemblies 41 are respectively connected one-to-one with the two clamping assemblies 31, it ensures that the movement of the operating component 20 is converted into synchronous movement of the two clamping assemblies 31. This ensures that both maintain a consistent displacement and velocity when approaching or moving away from the object, thereby creating a symmetrical and balanced clamping effect when gripping the object. This reduces the imbalance of force on the object caused by uncoordinated movements of the clamping assemblies 31, effectively ensuring the stability of the data acquisition device when gripping the object and reducing the risk of the object falling off.

[0030] Further, see Figures 1 to 5 and Figure 10As shown, the operating component 20 in this embodiment includes a slider 21, an elastic reset component 22, and an operating component 23. The slider 21 is disposed on the support 10 and can move along a first direction or a second direction opposite to the first direction, and both linkage assemblies 41 are connected to the slider 21. The operating component 23 is disposed on the support 10 and connected to the slider 21. The elastic reset component 22 is disposed on the support 10 and can deform under the action of the operating component 23. When the operating component 23 is subjected to an external force that causes the slider 21 to move along the first direction, the elastic reset component 22 deforms and stores elastic potential energy. Simultaneously, the two linkage assemblies 41 move synchronously with the slider 21 to place the two clamping assemblies 31 in a clamping position. When the external force is removed, the elastic reset component 22 releases the stored elastic potential energy, causing the slider 21 to move along the second direction, thereby causing the two linkage assemblies 41 to move synchronously to place the two clamping assemblies 31 in a released position. It should be noted that the "first direction" in this application refers to... Figure 7 The direction indicated by the middle arrow X; "second direction" refers to Figure 7 The direction indicated by the middle arrow Y.

[0031] In actual use of this data acquisition device, the operator applies external force to the operating component 23, causing it to move the sliding component 21 along a first direction. This, in turn, causes the two linkage assemblies 41 connected to the sliding component 21 to move synchronously, thereby bringing the two clamping assemblies 31 closer together and into a clamping position. During the movement of the sliding component 21 along the first direction, the elastic reset component 22 undergoes elastic deformation to store elastic potential energy. After the data acquisition is completed, the operator only needs to stop applying external force to the operating component 23. At this time, the elastic reset component 22 will immediately release the stored elastic potential energy to drive the sliding component 21 to reset along a second direction. The reset action of the sliding component 21 is also synchronously transmitted to the two linkage assemblies 41, thereby causing the two clamping assemblies 31 to move away from each other and switch from the clamping position to the release position. In this embodiment, the clamping action of the two clamping assemblies 31 can be completed by applying external force to the operating component 23. The structure is simple, and the operation is convenient and quick. Meanwhile, during the process of switching the two clamping components 31 from the clamping position to the release position, no additional manual intervention from the operator is required. This avoids the problem of uneven force during manual reset, which may cause the clamping component 31 to loosen on one side first and the object to tilt and fall off. It also allows the object to be smoothly released from the clamp without external interference, reducing the impact of improper release action on the object or the collected data, and effectively improving the stability of the data acquisition device.

[0032] In other words, in this embodiment, the operating component 23 serves as the connecting carrier between the external force and the sliding component 21, allowing the operator to drive the sliding component 21 to slide through a convenient operating method, thus improving the ease of operation of the data acquisition device. Simultaneously, the directional movement of the sliding component 21 and the automatic reset function of the elastic reset component 22 create a closed-loop control for the entire clamping and releasing process. During clamping, the clamping force is precisely controlled by external force, and during release, the elastic force achieves a smooth reset, improving both the controllability and stability of the clamping action and enhancing the reliability of the device during long-term repeated use.

[0033] Further, see Figure 5 As shown, in one embodiment of this application, the elastic reset component 22 includes a first elastic reset member 221, which is disposed on the support member 10 and is telescopically connected between the sliding member 21 and the support member 10. When the operating member 23 is subjected to an external force, the sliding member 21 moves along a first direction to stretch the first elastic reset member 221 and store elastic potential energy. When the external force is removed, the sliding member 21 moves along a second direction under the contraction of the first elastic reset member 221.

[0034] Specifically, when the operating component 23 is driven by an external force, the sliding component 21 moves synchronously with the operating component 23 along the first direction. At this time, the first elastic reset component 221 connected to the sliding component 21 is gradually stretched, converting the work done by the external force into elastic potential energy and storing it during the stretching process. When the external force acting on the operating component 23 is removed, the elastic potential energy stored in the first elastic reset component 221 is released. The first elastic reset component 221 generates a reverse driving force through its own contraction, driving the sliding component 21 to move along the second direction opposite to the first direction, ultimately causing the sliding component 21 and the operating component 23 to return to their initial positions. This design, through the combination of mechanical structure and elastic deformation, achieves automatic reset of the sliding component 21 after movement, completing the reset action without an additional power source, simplifying the complexity of the overall structure. At the same time, the force transmission during the elastic reset process is smooth, effectively buffering the impact during the movement of the sliding component 21, reducing frictional loss between components, and extending the service life of the structure. In addition, the retractable connection method adapts to the linear movement of the sliding component 21 along a fixed direction, ensuring a stable reset path, avoiding movement deviation, and ensuring the accuracy and reliability of the overall structure operation.

[0035] Optionally, the first elastic reset member 221 in this embodiment includes a spring, a leaf spring, or an elastic rope, etc. Any other variation of the concept of this application is within the protection scope of this application.

[0036] Further, see Figure 10As shown, in another embodiment of this application, the elastic reset component 22 includes a second elastic reset member 222, which is rotatably disposed between the support member 10 and the operating member 23. The first end of the second elastic reset member 222 abuts against the support member 10, and the second end of the second elastic reset member 222 opposite to the first end abuts against the operating member 23. When the operating member 23 is subjected to an external force and drives the sliding member 21 to move in the first direction, the second elastic reset member 222 undergoes torsional deformation around its own rotation fulcrum to store elastic potential energy. When the external force is removed, the second elastic reset member 222 releases the stored elastic potential energy and rotates in the opposite direction around its own rotation fulcrum. Under the reset action of the second elastic reset member 222, the operating member 23 drives the sliding member 21 to move in the second direction.

[0037] Specifically, when the operating member 23 is subjected to an external force and causes the sliding member 21 to move along the first direction, the second end of the second elastic reset member 222, which abuts against the operating member 23, moves synchronously with the operating member 23, causing the second elastic reset member 222 to undergo torsional deformation around its own rotation fulcrum. During this process, the work done by the external force is converted into the elastic potential energy of the second elastic reset member 222 and stored. When the external force acting on the operating member 23 is removed, the elastic potential energy stored in the second elastic reset member 222 is released, and the second elastic reset member 222 rotates in the opposite direction around the rotation fulcrum to return to its initial state. Its second end pushes the operating member 23 to reset through the abutment action, thereby causing the sliding member 21 to move along the second direction opposite to the first direction, and finally causing the operating member 23 and the sliding member 21 to return to their initial positions. This design, by utilizing the combination of a rotatable structure and torsional deformation, achieves the linkage reset of the operating member 23 and the sliding member 21, completing the reset action without the need for additional drive components, greatly simplifying the overall structural layout of the device. Meanwhile, the uniform release of force during torsional deformation effectively reduces the impact speed of the operating component 23 and the sliding component 21 during reset, reduces collision damage between components, and extends the overall service life of the device. Furthermore, the connection method of abutting at both ends and the setting of the rotatable fulcrum ensure that the second elastic reset component 222 maintains a stable force transmission path during the force application and reset process, preventing the operating component 23 or the sliding component 21 from jamming due to force deviation, thus ensuring the smoothness and accuracy of the device's operation.

[0038] Optionally, the second elastic reset member 222 in this embodiment includes a torsion spring, an elastic sheet, a coil spring, etc. Any other variation of the concept of this application is within the protection scope of this application.

[0039] Further, see Figure 5 and Figure 8As shown, the transmission mechanism 40 in this embodiment further includes two transmission components 42, which are connected one-to-one with two connecting rod assemblies 41. The end of each transmission component 42 away from the connecting rod assembly 41 is hinged to the sliding member 21. When the sliding member 21 moves along a first direction or a second direction, the two transmission components 42 respectively drive the two connecting rod assemblies 41 (i.e., the two transmission components 42 respectively drive their respective corresponding connecting rod assemblies 41) to rotate in opposite directions. It can be understood that when the sliding member 21 moves along the first direction, one of the two connecting rod assemblies 41 rotates along the first rotation direction (…). Figure 8 The first link assembly 41 rotates in the direction indicated by the middle arrow O, while the second link assembly 41 rotates in a second direction opposite to the first rotation direction. Figure 8 Rotate in the direction indicated by the middle arrow P; when the slider 21 moves in the second direction, the two linkage assemblies 41 rotate in the opposite direction to the previous one (that is, the one originally along the first rotation direction is changed to the second rotation direction, and the one originally along the second rotation direction is changed to the first rotation direction).

[0040] Specifically, in this embodiment, two transmission components 42 are connected to two connecting rod assemblies 41 in a one-to-one correspondence, and the end of each transmission component 42 away from the connecting rod assembly 41 is hinged to the sliding member 21. In this way, when the sliding member 21 moves in the first direction or the second direction, the linear motion of the sliding member 21 can be converted into the rotational motion of the connecting rod assembly 41 through the two transmission components 42, and the two transmission components 42 can be constrained to drive the two connecting rod assemblies 41 to rotate in opposite directions respectively. In other words, when the slider 21 moves along the first direction to clamp the two clamping components 31, the two transmission components 42 can drive the two linkage components 41 to rotate along the first rotation direction and the second rotation direction respectively, ensuring that the two clamping components 31 smoothly approach the object from both sides, avoiding clamping offset caused by deviation of the rotation direction or inconsistent angle of the linkage components 41; when the slider 21 resets along the second direction to release the two clamping components 31, the two transmission components 42 can again drive the two linkage components 41 to rotate along the second rotation direction and the first rotation direction respectively, so that the two clamping components 31 can simultaneously detach from the object, preventing the object from falling due to the slow rotation of the linkage component 41 on one side.

[0041] Further, see Figures 8 to 9 , Figures 11 to 12 As shown, the transmission component 42 in this embodiment includes a transmission rod 421 and a rotating part 422 connected to the transmission rod 421. The end of the transmission rod 421 away from the rotating part 422 is hinged to the sliding member 21. The rotating part 422 is rotatably mounted on the support member 10. The connecting rod assembly 41 is connected to the rotating part 422.

[0042] Specifically, in this embodiment, the transmission rod 421 is connected to the sliding member 21 by a hinge, which can flexibly follow the sliding member 21 to move in the first or second direction, and can also convert the linear displacement of the sliding member 21 into its own swinging motion. At the same time, since the hinge point can rotate freely, rigid friction between the sliding member 21 and the transmission rod 421 is avoided when the sliding member 21 moves, reducing component wear and ensuring that power transmission is smooth. The rotating part 422 is rotatably mounted on the support member 10, so that the support member 10 can provide a stable rotation fulcrum for the rotating part 422, allowing the rotating part 422 to always rotate around a fixed axis, avoiding misalignment of the linkage assembly 41 due to deviation of the rotation trajectory. In other words, when the transmission rod 421 swings with the sliding member 21, it will drive the rotating part 422 to rotate stably around the mounting point on the support member 10. Then, through the connection between the rotating part 422 and the connecting rod assembly 41, the rotational motion is accurately transmitted to the connecting rod assembly 41. This effectively ensures that when the two transmission components 42 drive the corresponding connecting rod assemblies 41 to rotate in opposite directions, the rotation angle and speed of the two connecting rod assemblies 41 remain consistent. There will be no situation where one side rotates too fast or the angle deviates. This further enhances the force balance when the clamping assembly 31 clamps and the smoothness of the action when releasing.

[0043] Further, see Figures 8 to 9 As shown, the transmission component 42 in this embodiment also includes a connecting shaft 423, which is disposed on the support member 10. The rotating part 422 is sleeved on the connecting shaft 423 and can rotate around the connecting shaft 423. An encoder 50 is disposed on the support member 10. The encoder 50 is located at the bottom of the connecting shaft 423 and is coaxially disposed with the connecting shaft 423. The encoder 50 is connected to the connecting rod assembly 41 for transmission to detect the rotation angle of the connecting rod assembly 41.

[0044] Specifically, in this embodiment, the connecting shaft 423 provides a fixed rotation reference for the rotating part 422, and the encoder 50 monitors the rotation angle of the rotating part 422 in real time, further enhancing the accuracy of the movement of the linkage assembly 41 and the controllability of the clamping control. Since the encoder 50 is located at the bottom of the connecting shaft 423 and is coaxial with the connecting shaft 423, and is also connected to the rotating part 422 in a transmission manner, the encoder 50 can capture the changes in the rotation angle of the rotating part 422 in real time and synchronously, achieving high-precision and delay-free detection of the rotation angle of the rotating part 422.

[0045] It is worth mentioning that, since the linkage assembly 41 in this embodiment is connected to the rotating part 422, the linkage assembly 41 can rotate synchronously when the rotating part 422 rotates. When the encoder 50 detects the rotation angle of the rotating part 422, the rotation angle of the linkage assembly 41 can be obtained. This allows the operator or subsequent control system to reverse-calculate the displacement of the linkage assembly 41 and the opening and closing degree of the clamping assembly 31 based on the detection data. For example, when the encoder 50 detects that the rotation angle of the linkage assembly 41 reaches a preset value, it can determine that the clamping assembly 31 has been tightened to the appropriate force, avoiding insufficient clamping force or over-clamping caused by the operator judging by feel alone. If an abnormal rotation angle of the linkage assembly 41 is detected (such as sudden jamming or sudden change in angle), it can also provide timely warning of possible jamming or damage to the linkage assembly 41, facilitating quick troubleshooting and reducing the impact of device failure on data acquisition.

[0046] Further, see Figures 8 to 9 As shown, the transmission component 42 in this embodiment also includes a connecting shaft 423. The connecting shaft 423 is disposed on the support member 10. The rotating part 422 is sleeved on the connecting shaft 423 and can rotate around the connecting shaft 423. A retaining ring 43 is sleeved on the connecting shaft 423. The retaining ring 43 is located on the side of the rotating part 422 near the connecting rod assembly 41, and the retaining ring 43 and the connecting shaft 423 are connected by an interference fit.

[0047] Specifically, when the rotating part 422 drives the connecting rod assembly 41, it generates axial force due to power transmission. Without effective limiting, this can easily cause the rotating part 422 to move axially along the connecting shaft 423. Therefore, in this embodiment, a retaining ring 43 is provided on the connecting shaft 423 and installed on the side of the rotating part 422 closest to the connecting rod assembly 41. This limits the rotation of the rotating part 422, preventing axial displacement during rotation around the connecting shaft 423. Simultaneously, in this embodiment, the retaining ring 43 and the connecting shaft 423 are connected by an interference fit. This ensures a tight fit between the retaining ring 43 and the connecting shaft 423, firmly fixing it in a preset position without additional fasteners. This prevents axial movement or circumferential displacement due to device vibration or operational impacts, providing a rigid and reliable axial limiting barrier for the rotating part 422.

[0048] Further, see Figure 7 As shown, the operating member 23 in this embodiment includes an operating lever 231. One end of the operating lever 231 is rotatably connected to the support member 10 to form a rotation point, and the other end of the operating lever 231 is connected to the sliding member 21. When the operating lever 231 is subjected to an external force or the external force is removed, it can rotate around the rotation point to make the sliding member 21 move in a first direction or a second direction.

[0049] Specifically, when an object needs to be clamped, the operator only needs to apply external force to the operating lever 231, which will rotate around the pivot point, thereby causing the sliding member 21 to move along the first direction, and thus causing the two clamping components 31 to be in the clamping position. During this process, the operator can flexibly adjust the displacement of the sliding member 21 by controlling the magnitude of the external force applied to the operating lever 231, thereby precisely controlling the approach speed and final clamping force of the two clamping components 31. When the object needs to be released, the operator only needs to remove the external force applied to the operating lever 231. The first elastic reset member 221 connected between the sliding member 21 and the support member 10 or the second elastic reset member 222 connected between the operating lever 231 and the support member 10 will immediately release the stored elastic potential energy, generating a stable reverse pulling force through the reset action, driving the sliding member 21 to reset along the second direction, and thus causing the two clamping components 31 to be in the release position.

[0050] In this embodiment, by rotatably connecting one end of the operating lever 231 to the support member 10, the operating lever 231 can not only rotate strictly around the fixed point when subjected to external force or when the external force is removed, ensuring that the movement trajectory of the operating lever 231 is deterministic and regular, effectively avoiding transmission deviation caused by chaotic movement trajectory, but also reducing the friction force at the contact point between the operating lever 231 and the support member 10, and reducing the degree of wear between components.

[0051] Further, see Figure 6 and Figure 11 As shown, in this embodiment, one of the support member 10 and the sliding member 21 is provided with a guide rail 13 extending along a first direction, and the other is provided with a first groove 211 adapted to the guide rail 13. That is to say, the support member 10 may be provided with the guide rail 13, and the sliding member 21 may be provided with the first groove 211; alternatively, the support member 10 may be provided with the first groove 211, and the sliding member 21 may be provided with the guide rail 13. This embodiment Figure 6 The diagram shows the case where the support member 10 is provided with a guide rail 13 and the slider 21 is provided with a first groove 211.

[0052] Specifically, this embodiment, by extending the guide rail 13 along the first direction, can strictly limit the movement trajectory of the slider 21, ensuring that the slider 21 always moves along a preset straight path during force application or reset, avoiding motion interference or power transmission deviation between the linkage assemblies 41 due to slider 21 offset, thereby ensuring that the two linkage assemblies 41 can maintain synchronous movement under the drive of the slider 21. At the same time, the matching cooperation between the first slide groove 211 and the guide rail 13 makes the movement of the slider 21 smoother and more stable, reducing the lag in the action of the clamping assembly 31 caused by jamming.

[0053] Further, see Figures 1 to 4As shown, the linkage assembly 41 in this embodiment includes a first linkage 411, a second linkage 412, and a third linkage 413. The first end of the first linkage 411 rotates under the drive of the operating component 20; the second linkage 412 is spaced apart from the first linkage 411, and the first end of the second linkage 412 is hinged to the support member 10; the first end of the third linkage 413 is hinged to the second end of the first linkage 411, the second end of the third linkage 413 is hinged to the second end of the second linkage 412, and the clamping assembly 31 is installed on the third linkage 413.

[0054] Specifically, the first end of the first link 411 rotates under the drive of the operating component 20, providing power input to the entire link assembly 41. When the first link 411 rotates under the drive of the operating component 20, it pulls the first end of the third link 413 to move with the first link 411. At the same time, the second end of the second link 412, which is hinged to the support member 10, provides limiting support to the third link 413, causing the third link 413 to move along a preset trajectory under the combined action of the two. Meanwhile, in this embodiment, the first link 411, the second link 412, and the third link 413 form a multi-link structure, which can effectively disperse the stress during the power transmission process. When the power received by the first link 411 is transmitted to the clamping assembly 31 through the third link 413, the second link 412 can share part of the force, reducing the stress load on the first link 411 or the third link 413, reducing the risk of link deformation or breakage, and improving the durability of the link assembly 41 for long-term use. In addition, the hinged connection between each link makes the movement more flexible and prevents jamming or stuckness, ensuring that the clamping assembly 31 can smoothly switch between clamping and releasing states under the control of the operating component 20.

[0055] Further, see Figures 1 to 4 , Figures 13 to 17 As shown, each clamping assembly 31 in this embodiment includes at least one type of clamping member 311, which is detachably mounted on the connecting rod assembly 41. This embodiment... Figure 12 The first type of clamping member 311 is shown; Figure 13 The second type of clamping member 311 is shown; Figure 15 The case of the third type of clamping member 311 is shown; Figure 16 The case of the fourth type of clamping member 311 is shown.

[0056] Specifically, different models of clamping parts 311 can be adapted to objects of different specifications and shapes to be clamped, effectively improving the adaptability of the clamping assembly 31 and meeting diverse clamping needs. At the same time, since the clamping parts 311 are detachably mounted on the linkage assembly 41, when the clamping parts 311 wear out or become damaged due to long-term use, or when it is necessary to replace them with different models according to the object to be clamped, the operator does not need to disassemble the entire linkage assembly 41, but only needs to disassemble and replace the corresponding clamping parts 311. This not only simplifies the operation process and shortens the maintenance or replacement time, but also reduces interference with other components and reduces the risk of component damage caused by complex disassembly.

[0057] Further, see Figures 12 to 16 As shown, the clamping member 311 in this embodiment is provided with an anti-slip part 312, and the anti-slip part 312 is provided with at least one protruding structure 3121. Optionally, the protruding structure 3121 in this embodiment can be one, two, three or more, and this application does not make a specific limitation.

[0058] Specifically, the anti-slip part 312 enhances the frictional performance between the clamping member 311 and the contact surface of the object to be clamped, preventing the object from sliding or shifting during clamping due to the smooth contact surface, thus effectively improving clamping stability. Simultaneously, at least one protruding structure 3121 on the anti-slip part 312 further optimizes the anti-slip effect. The protruding structure 3121 can form a tighter engagement with the surface of the object to be clamped, effectively increasing the static friction between them by increasing local contact pressure and the roughness of the contact point. Even when there are slight fluctuations in clamping force or the object to be clamped is subjected to minor external force interference, it can effectively prevent sliding.

[0059] For example, the anti-slip part 312 in this embodiment includes anti-slip soft rubber. The anti-slip soft rubber can be connected to the clamping member 311 by means of bonding, fitting, screwing, snapping, etc. Any other variation under the concept of this application is within the protection scope of this application.

[0060] Furthermore, the clamping component 311 in this embodiment includes at least one of thermoplastic polyurethane (TPU) clamping component and soft rubber clamping component. Specifically, both thermoplastic polyurethane (TPU) and elastic soft rubber materials possess good flexibility and elasticity, thereby adapting to objects of different shapes or sizes and improving clamping adaptability. At the same time, the soft texture of thermoplastic polyurethane and soft rubber materials can effectively buffer the clamping force, preventing scratches, indentations, and other damage to the surface of the clamped object, while also reducing discomfort when the clamping structure comes into contact with the human body, thus improving the overall user experience.

[0061] Further, see Figure 14As shown, in this embodiment, one of the clamping member 311 and the connecting rod assembly 41 is provided with a second sliding groove 313, and the other of the two is provided with a sliding protrusion 414 adapted to the second sliding groove 313; wherein, the second sliding groove 313 has at least one first inclined surface 3131, and the sliding protrusion 414 has at least one second inclined surface 4141 that fits against the first inclined surface 3131.

[0062] Specifically, the adaptive design of the second slide groove 313 and the sliding protrusion 414 allows the installation of the clamping member 311 and the connecting rod assembly 41 without complex fasteners. Initial positioning can be achieved simply by pushing one of the sliding protrusions 414 along the extension direction of the other's second slide groove 313, simplifying the replacement process of the clamping member 311. This is especially beneficial in batch data acquisition scenarios where frequent switching of the clamping member 311 is required, shortening replacement time and improving operational efficiency. Simultaneously, this embodiment provides at least one first inclined surface 3131 on the second slide groove 313 and at least one second inclined surface 4141 on the sliding protrusion 414. This ensures a tight surface contact between the sliding protrusion 414 and the second slide groove 313, increasing the friction between them.

[0063] Further, see Figures 1 to 5 As shown, the support member 10 in this embodiment has a mounting cavity 11 and a protective member 12. At least a portion of the operating component 20 is located in the mounting cavity 11, and the protective member 12 covers the top of the mounting cavity 11. It can be understood that the sliding member 21 and the first elastic reset member 221 in this embodiment are located inside the mounting cavity 11.

[0064] Specifically, the mounting cavity 11 provides space for at least part of the operating components 20, while the protective element 12 covers the top of the mounting cavity 11, further enhancing the protective effect. On the one hand, the protective element 12 can form a physical barrier to prevent foreign objects or liquids falling from above from seeping into the mounting cavity 11, extending the service life of the operating components 20; on the other hand, the protective element 12 can isolate the components inside the mounting cavity 11 from the operator, preventing the operator from accidentally touching the moving components inside the mounting cavity 11 during operation, thus improving the safety of the device.

[0065] Further, see Figures 1 to 2 As shown, the data acquisition device in this embodiment further includes at least one camera 100, which is mounted on the support member 10 for at least capturing images of objects. Optionally, the camera 100 in this embodiment can be one, two, three, or more.

[0066] Specifically, the camera 100 is fixed to the support 10 and can synchronously align with the object to be clamped or collected as the overall posture of the device adjusts. Its shooting function can directly acquire the object's appearance image, size information, or positional features. For example, before the clamping operation, the operator can check the real-time image of the camera 100 to confirm whether the object is located at the symmetrical center of the two clamping components 31, avoiding misalignment of the clamping components 31 due to visual deviation. During the data acquisition process, the camera 100 can work with other acquisition devices (such as sensors) to synchronously record the surface details of the object, forming a multi-dimensional data system of image data and physical parameters, meeting more complex acquisition needs such as the detection of object appearance defects and morphological analysis.

[0067] Further, see Figure 3 and Figure 7 As shown, the support member 10 in this embodiment has a mounting cavity 11, and the data acquisition device further includes a circuit control board 60, which is disposed within the mounting cavity 11, and a heat-conducting element 70 is provided between the inner wall of the mounting cavity 11 and the circuit control board 60. Optionally, the heat-conducting element 70 in this embodiment includes an aluminum plate, a copper plate, etc.

[0068] Specifically, the mounting cavity 11 isolates the circuit control board 60 from the external environment, effectively preventing dust, moisture, impurities, etc., from adhering to the surface of the circuit control board 60. This avoids faults such as short circuits and component corrosion caused by foreign matter adhesion, and also prevents physical damage to the circuit control board 60 from external collisions and scratches. At the same time, since the circuit control board 60 generates heat due to component power consumption during operation, if the heat accumulates and cannot be dissipated in time, it can easily lead to excessive component temperature, performance degradation, or even serious faults such as system crashes and burnout. Therefore, in this embodiment, by setting a heat-conducting component 70 between the inner wall of the mounting cavity 11 and the circuit control board 60, the heat generated by the circuit control board 60 can be quickly conducted to the support component 10, thereby dissipating the heat to the external environment through the support component 10. This achieves rapid cooling of the circuit control board 60, ensuring that it is always within a suitable operating temperature range, and guaranteeing the stability and timeliness of data processing and signal transmission.

[0069] For example, in this embodiment, the circuit control board 60 and the heat-conducting component 70 can be bonded together with thermally conductive adhesive.

[0070] Further, see Figures 1 to 4 As shown, the support member 10 in this embodiment is provided with at least one external interface 80. The external interface 80 can improve the data interaction capability and functional expandability of the data acquisition device.

[0071] Optionally, in this embodiment, the external interface 80 can be configured as one, two, three, or more. Figures 1 to 4The diagram shows the case where there are three external interfaces 80, namely a microphone interface, an SD card interface, and a power interface.

[0072] Further, see Figure 4 As shown, the data acquisition device in this embodiment also includes a base 90, and the support member 10 is detachably mounted on the base 90. Specifically, the base 90 provides stable support for the support member 10, and when it is necessary to hold the support member 10 to flexibly grip an object, the support member 10 can simply be removed from the base 90.

[0073] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0074] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this application.

[0075] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
