Description

Technical Field

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

[0002] Training a robot model requires the collection of a large amount of data to enable the robot to perform more precise operations based on the data.

[0003] In related technologies, there are some data acquisition devices with grippers to acquire large amounts of data; however, these data acquisition devices are not convenient to use. Utility Model Content

[0004] This application provides a data acquisition device to solve the problem that existing data acquisition devices with the same function as grippers are not convenient to use.

[0005] This application provides a data acquisition device, including a mounting base, a handle, two clamping members, and a transmission mechanism. The handle is slidably connected to the mounting base. Along the arrangement direction of the two clamping members, the two clamping members are slidably connected to the mounting base, and the sliding direction is different from the sliding direction of the handle. The transmission mechanism is connected to the handle and the two clamping members. The transmission mechanism is used to drive the two clamping members to slide in a direction that moves closer to or further away from each other when the handle slides relative to the mounting base.

[0006] The data acquisition device provided in this application allows the operator to slide the handle relative to the mounting base. The handle, through a transmission mechanism, drives two clamping components to slide closer or further apart, thereby clamping or releasing an object. Since the operator only needs to slide the handle to control the clamping components to grasp or release the object, the closing speed and clamping force of the end clamping components are linearly mapped to the operator's gripping speed and force. This allows the operator to receive real-time feedback and adjust speed and gripping force, making operation more convenient.

[0007] In some embodiments, the mounting base includes a first limiting portion. Along the sliding direction of the handle, at least a portion of the handle is located on one side of the first limiting portion and is disposed opposite to the first limiting portion.

[0008] In some embodiments, the mounting base further includes a second limiting portion. Along the sliding direction of the handle, at least a portion of the handle is located between the second limiting portion and the first limiting portion, and is disposed opposite to the second limiting portion.

[0009] In some embodiments, the handle has a gripping hole, the opening direction of which is different from the sliding direction of the handle.

[0010] In some embodiments, the mounting base has a mounting hole that extends through the mounting base along the opening direction of the holding hole; the handle is located inside the mounting hole.

[0011] In some embodiments, the handle is provided with a gripping portion for the operator's fingers to grasp, and the mounting base is provided with a support portion for supporting the operator's palm.

[0012] In some embodiments, the data acquisition device further includes an elastic element. The elastic element generates a spring force that causes the handle to slide in the sliding direction, so that the handle is reset under the action of the spring force of the elastic element.

[0013] In some embodiments, the elastic element is used to generate a spring force that causes the handle to move the two clamping members away from each other via a transmission mechanism.

[0014] In some embodiments, the elastic element includes a spring. The handle has a stop post. One end of the spring is fitted onto the stop post.

[0015] In some embodiments, the transmission mechanism includes a rack and pinion mechanism and a lead screw and nut mechanism. The rack and pinion mechanism is connected to two clamping members. The rack and pinion mechanism is used to move the two clamping members away from or towards each other. The lead screw and nut mechanism is connected to the handle and also to the rack and pinion mechanism. The lead screw and nut mechanism is used to drive the rack and pinion mechanism to move when the handle moves relative to the mounting base.

[0016] In some embodiments, the gear and rack mechanism includes a drive gear and two drive racks. The drive gear is rotatably connected to the mounting base. The two drive racks are slidably connected to the mounting base and mesh with the drive gear. One drive rack is connected to a clamping member. The lead screw and nut mechanism includes a lead screw and a nut. The lead screw is rotatably connected to the mounting base and to the drive gear. The nut is sleeved on the lead screw and connected to a handle. The nut is used to slide along the extension direction of the lead screw under the action of the handle, so as to drive the lead screw to rotate relative to the mounting base.

[0017] In some embodiments, the data acquisition device further includes two housings. The housings cover at least a portion of the rack and pinion mechanism and are connected to the rack and pinion mechanism. Clamping members are disposed on the housings.

[0018] In some embodiments, the mounting base has a groove. The data acquisition device also includes two sliders. The sliders are connected to the housing and the rack. The sliders are slidably connected to the groove. Attached Figure Description

Detailed Implementation

[0025] The technical solutions of the embodiments 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.

[0026] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or system that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or system. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or system that includes that element.

[0027] In the following description, the terms "first," "second," etc., are used for descriptive convenience only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "a plurality of" means two or more.

[0028] In this application, unless otherwise expressly specified and limited, the term "connection" shall be interpreted broadly. For example, "connection" may be a fixed mechanical connection, a detachable mechanical connection, or an integral part; or, "connection" may be a direct connection or an indirect connection through an intermediate medium.

[0029] Furthermore, in the embodiments of this application, directional terms such as "up," "down," "left," "right," "horizontal," and "vertical" may be defined relative to the orientation in which the components are schematically placed in the accompanying drawings. It should be understood that these directional terms can be relative concepts, used for relative description and clarification, and can change accordingly depending on the orientation in which the components are placed in the accompanying drawings.

[0030] The terms "parallel," "perpendicular," and "identical" (e.g., identical length, identical width, etc.) mentioned in the embodiments of this application are all relative to the current technological level, and not absolute and strict mathematical definitions. There can be a predetermined angular deviation between two mutually parallel or perpendicular components. In one embodiment, the predetermined angle can be within the range of ±10°, for example, a predetermined angular deviation of ±5°.

[0031] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] This application provides a data acquisition device capable of collecting data. The collected data can be used for training large-scale models in embodied intelligence and robotic operations. Operators can use the data acquisition device to collect data without the need for robots, allowing for faster expansion of the data volume.

[0033] The data acquisition device provided in the embodiments of this application will be further described below, such as... Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a data acquisition device 100 provided in an embodiment of this application. The data acquisition device 100 may include a mounting base 10, a handle 20, two clamping members 30, and a transmission mechanism 40. The two clamping members 30 are slidably connected to the mounting base 10 along the arrangement direction of the two clamping members 30.

[0034] Therefore, as Figure 2 As shown, Figure 2 for Figure 1 The diagram shows the structure of the data acquisition device 100 in a clamping state. When the two clamping members 30 slide towards each other, they can clamp the object between them, thus achieving the clamping function. The specific shape of the two clamping members 30 can be designed according to actual conditions, as long as it can clamp the object; this application does not impose further limitations. For example, as shown... Figure 1 As shown, the clamping member 30 can be roughly tapered in shape.

[0035] The handle 20 is slidably connected to the mounting base 10, and the sliding direction of the two clamping members 30 is different from the sliding direction of the handle 20. The transmission mechanism 40 is connected to the handle 20 and the two clamping members 30. The transmission mechanism 40 can be used to drive the two clamping members 30 to slide in a direction closer to or further away from each other when the handle 20 slides relative to the mounting base 10.

[0036] It is understood that the specific angle between the sliding direction of the two clamping members 30 and the sliding direction of the handle 20 can be designed according to the actual situation. For example, the sliding direction of the two clamping members 30 and the sliding direction of the handle 20 can be perpendicular to each other. Alternatively, the angle between the sliding direction of the two clamping members 30 and the sliding direction of the handle 20 can also be less than 90°.

[0037] For example, when using the data acquisition device 100, with the operator's front as a reference, the sliding direction of the two clamping parts 30 can be left and right when the operator holds the data acquisition device 100. At this time, the sliding direction of the handle 20 can be forward and backward. In this way, when the operator operates the handle 20, their fingers can extend and retract the handle 20 in the forward and backward direction, making operation more convenient.

[0038] Based on this, the data acquisition device 100 provided in this application embodiment allows the operator to operate the handle 20 by hand, causing the handle 20 to slide relative to the mounting base 10. The handle 20 can then drive the two clamping members 30 to slide towards or away from each other via the transmission mechanism 40, thereby achieving the clamping or releasing of objects by the two clamping members 30. Since the operator only needs to operate the handle 20 to slide, the clamping members 30 can be controlled to slide to clamp or release objects. This allows for a linear mapping relationship between the closing speed and clamping force of the end clamping member 30 and the operator's gripping speed and gripping force. During use, the operator can receive better real-time feedback and adjust the speed and gripping force, making operation more convenient.

[0039] Furthermore, as mentioned above, since the sliding direction of the two clamping parts 30 is different from the sliding direction of the handle 20, the operator can hold the handle 20 at a more comfortable angle when operating the handle 20 with their fingers (for example, the operator's fingers moving back and forth can make the clamping parts 30 move away from or closer to each other in the left and right directions).

[0040] To facilitate the sliding of handle 20, such as Figure 1 As shown, in some embodiments, the mounting base 10 may have a sliding groove 111. A portion of the handle 20 may be located within the sliding groove 111. In this way, the handle 20 can slide along the direction of the sliding groove 111, ensuring a smooth sliding effect.

[0041] Of course, in other embodiments, the handle 20 can also be formed as a groove structure. Correspondingly, the mounting base 10 can be formed with a protruding structure. In this case, the sliding effect of the handle 20 can also be ensured by the groove structure of the handle 20 and the protruding structure on the mounting base 10.

[0042] In some embodiments, such as Figure 1 As shown, the mounting base 10 may include a first limiting portion 101. Along the sliding direction of the handle 20, at least a portion of the handle 20 is located on one side of the first limiting portion 101 and is disposed opposite to the first limiting portion 101.

[0043] Therefore, when the handle 20 slides relative to the mounting base 10, when the handle 20 slides to the first limiting part 101, the first limiting part 101 can abut against the handle 20, thereby limiting the continued sliding of the handle 20 and playing a limiting role, so as to prevent the handle 20 from sliding too much, thereby preventing the two clamping parts 30 from moving too much and affecting normal operation.

[0044] Similarly, in some embodiments, such as Figure 1As shown, the mounting base 10 may also include a second limiting portion 102. Along the sliding direction of the handle 20, at least a portion of the handle 20 is located between the second limiting portion 102 and the first limiting portion 101, and is disposed opposite to the second limiting portion 102.

[0045] Therefore, when the handle 20 slides relative to the mounting base 10, when the handle 20 slides to the second limiting part 102, the second limiting part 102 can abut against the handle 20, thereby limiting the sliding of the handle 20 in the direction away from the first limiting part 101, playing a limiting role, and preventing the handle 20 from sliding too much in the direction away from the first limiting part 101, thereby preventing the two clamping members 30 from moving too much in the other direction.

[0046] Of course, the mounting base 10 may also not include the first limiting part 101 and the second limiting part 102. In this case, in order to achieve the limiting effect, in some embodiments, the mounting base 10 may have a third limiting part and a fourth limiting part. The third limiting part and the fourth limiting part may be located on opposite sides of the clamping member 30 along the arrangement direction of the clamping member 30, and are disposed opposite to the clamping member 30.

[0047] In this way, the third and fourth limiting parts can limit the clamping member 30. Since the clamping member 30 can move in conjunction with the handle 20 through the transmission mechanism 40, the sliding of the handle 20 relative to the mounting base 10 can also be kept within a certain range, thus playing a limiting role.

[0048] In some embodiments, the handle 20 has a gripping hole 201, the opening direction of which is different from the sliding direction of the handle 20. Therefore, when using the handle, the operator's fingers can be inserted into the gripping hole 201 to operate the handle 20, facilitating operation.

[0049] Meanwhile, since the opening direction of the grip hole 201 is different from the sliding direction of the handle 20, the operator can easily operate the handle 20 by bending and straightening their fingers after inserting them into the grip hole 201. For example, the grip hole 201 of the handle 20 faces left and right. This makes it more convenient for the operator to slide the handle 20 back and forth using their fingers through the grip hole 201, allowing for better utilization of finger bending and straightening to operate the handle 20.

[0050] It is understandable that the specific shape of the handle 20 can be designed according to the actual situation. For example, such as Figure 1 As shown, the handle 20 can be annular, with the aforementioned gripping hole 201 formed on the inner side of the handle 20. Of course, in other embodiments, the handle 20 can also be a block structure. In this case, a blind hole or a through hole can be provided on the handle 20 to form the aforementioned gripping hole 201.

[0051] Of course, the handle 20 can also be designed in other ways to facilitate operator gripping. For example, in some embodiments, a gripping protrusion can be formed on the handle 20, allowing the operator to operate the handle 20 by gripping the protrusion. Alternatively, when using the data acquisition device 100, the operator can grip the handle 20 from one side along the sliding direction of the handle 20. In this case, the handle 20 can also be a columnar structure.

[0052] In some embodiments, the mounting base 10 has a mounting hole 103 that extends through the mounting base 10 along the opening direction of the gripping hole 201. The handle 20 is located inside the mounting hole 103. Thus, the handle 20 can be installed within the mounting hole 103. Simultaneously, the operator can use the mounting hole 103 and the gripping hole 201 to simultaneously grip both the mounting base 10 and the handle 20, making operation more convenient.

[0053] For example, such as Figure 1 and Figure 2 As shown, during operation, since the handle 20 is installed in the mounting hole 103, when the operator's fingers are inserted into the gripping hole 201 to operate, other parts of the operator's hand can use the mounting hole 103 to hold the mounting base 10, which can stably hold the mounting base 10 and maintain the stability of the operation.

[0054] In some embodiments, such as Figure 2 As shown, the handle 20 is provided with a gripping portion 203 for the operator's fingers to grasp. Therefore, when performing operations, the operator can grip the handle 20 through the gripping portion 203 to operate the handle 20. For example, as... Figure 2 As shown, the handle 20 is a roughly square ring structure, and one side of the handle 20 is the aforementioned gripping part 203.

[0055] In some embodiments, such as Figure 2 As shown, the mounting base 10 is provided with a support portion 104 for supporting the operator's palm. When the operator is operating, the support portion 104 provides support and a reaction force, allowing the fingers to smoothly operate the handle 20 and enabling the handle 20 to slide relative to the mounting base. For example, as... Figure 2 As shown, the mounting base 10 has a generally U-shaped structure, wherein the middle position of the U-shaped structure can be the aforementioned support portion 104.

[0056] It is understandable that the specific shape and composition of the mounting base 10 can be designed according to actual conditions. In some embodiments, such as Figure 1 As shown, the mounting base 10 may include a first mounting member 11. The first mounting member 11 may at least partially surround the periphery of the handle 20, and the handle 20 is slidably connected to the inner side of the first mounting member 11. Thus, the first mounting member 11 can form the aforementioned mounting hole 103, facilitating the operator to reach into the handle 20 for operation.

[0057] In some embodiments, such as Figure 1 and Figure 2 As shown, the mounting base 10 may further include a second mounting member 12. The second mounting member 12 is connected to the first mounting member 11, and the first mounting member 11 and the second mounting member 12 are arranged together around the periphery of the handle 20. The clamping member 30 can be slidably connected to the second mounting member 12 (directly or indirectly). In this case, the second mounting member 12 may include the aforementioned first limiting part 101, which can serve to limit the handle 20.

[0058] The specific form of the second mounting member 12 can also be designed according to the situation; it is only illustrated here as an example. For instance, the second mounting member 12 can be a plate-like structure. Thus, the second mounting member 12 can be easily installed with components such as the clamping member 30, making installation more convenient.

[0059] Of course, in some other embodiments, the mounting base 10 may not include the second mounting member 12. In this case, the first mounting member 11 may be annular, arranged around the periphery of the handle 20. In this case, the first mounting member 11 may directly form a complete mounting hole 103. In this case, the clamping member 30 may be slidably connected to the first mounting member 11.

[0060] In some embodiments, such as Figure 1 and Figure 2 As shown, the mounting base 10 may further include a third mounting member 13. The third mounting member 13 is located on the side of the second mounting member 12 away from the clamping member 30 and is connected to the second mounting member 12. In this case, as... Figure 1 As shown, the third mounting component 13 may include the aforementioned second limiting part 102.

[0061] Of course, in some other embodiments, the mounting base 10 may not include the third mounting member 13. In this case, the second mounting member 12 may be formed with a corresponding blocking structure to limit the handle 20 in another direction. It is known that, along the sliding direction of the handle 20, at least a portion of the handle 20 may be located between the blocking structure and the first limiting part 101, and is disposed opposite to the blocking structure.

[0062] The specific form of the third mounting component 13 can also be designed according to actual needs; it is only illustrated here as an example. For instance, the third mounting component 13 can be a U-shaped structure, and both ends of the third mounting component 13 can be connected to the second mounting component 12.

[0063] The third mounting member 13 can form a limiting space with the second mounting member 12. A portion of the handle 20 is located within the limiting space. In this way, the second mounting member 12 and the third mounting member 13 can limit the handle 20, thereby preventing the handle 20 from detaching.

[0064] Furthermore, the second mounting member 12 can be detachably connected to the third mounting member 13. Thus, during disassembly, the second mounting member 12 and the third mounting member 13 can be removed, allowing the handle 20 to be detached.

[0065] It is understood that the connection method between the second mounting member 12 and the third mounting member 13 can be selected according to the actual situation. In some embodiments, the second mounting member 12 and the third mounting member 13 can be interlocked by a limiting structure. For example, a mounting protrusion can be formed on the second mounting member 12, and a mounting groove can be formed on the third mounting member 13. Thus, a detachable connection between the second mounting member 12 and the third mounting member 13 can be achieved by the interlocking between the mounting protrusion and the mounting groove.

[0066] In some embodiments, such as Figure 1 and Figure 2 As shown, the data acquisition device 100 may further include an elastic element 50. The elastic element 50 is used to generate a spring force that causes the handle 20 to slide in the sliding direction, so that the handle 20 is reset under the action of the spring force of the elastic element 50. Thus, by setting the elastic element 50, the handle 20 can be automatically reset, which is more convenient for the operator during use, and there is no need for manual reset operation.

[0067] Of course, in some other embodiments, the data acquisition device 100 may not include the elastic element 50. In this case, the operator can manually reset the handle 20.

[0068] In some embodiments, the elastic element 50 is used to generate a force that causes the handle 20 to drive the two clamping members 30 in a direction away from each other via the transmission mechanism 40. In this case, when the operator applies external force, the two clamping members 30 can be moved closer together to clamp the item. When the operator removes the external force, the elastic element 50 can cause the two clamping members 30 to separate. In this case, the elastic element 50 is more in line with daily usage habits.

[0069] Of course, in other embodiments, the elastic element 50 can also be used to cause the handle 20 to move the two clamping members 30 toward each other via the transmission mechanism 40. In this case, when the operator applies external force, the two clamping members 30 can be moved away from each other to facilitate subsequent clamping of the item. When the operator removes the external force, the elastic element 50 can cause the two clamping members 30 to move closer together, so that the clamping members 30 can clamp the item.

[0070] In some embodiments, the elastic element 50 may include a spring. Thus, by utilizing the compression and unfolding of the spring, automatic reset of the handle 20 can be achieved. Wherein, as Figure 1 As shown, the handle 20 may have a limiting post 202. One end of the spring is sleeved on the limiting post 202. Thus, by setting the limiting post 202, the spring can be easily installed and limited, allowing the spring to be better installed on the handle 20.

[0071] Of course, the elastic element 50 can also be of other types, and the specific type can be selected according to the actual situation. For example, the elastic element 50 can also include a metal spring or a rubber elastic element. Thus, the handle 20 can be automatically reset by the elastic deformation of the metal spring or the rubber elastic element.

[0072] In some embodiments, such as Figure 1 As shown, the transmission mechanism 40 includes a gear and rack mechanism 41 and a lead screw and nut mechanism 42. The gear and rack mechanism 41 is connected to two clamping members 30. The gear and rack mechanism 41 is used to drive the two clamping members 30 to move away from or towards each other. The lead screw and nut mechanism 42 is connected to the handle 20 and also to the gear and rack mechanism 41. The lead screw and nut mechanism 42 is used to drive the gear and rack mechanism 41 to move when the handle 20 moves relative to the mounting base 10.

[0073] Therefore, the sliding motion of the handle 20 can be converted into rotational motion through the lead screw and nut mechanism 42. At the same time, since the lead screw and nut mechanism 42 is connected to the gear and rack mechanism 41, the rotation of the lead screw and nut mechanism 42 can be converted into sliding motion through the gear and rack mechanism 41, thereby driving the clamping member 30 to slide through the gear and rack mechanism 41, realizing the motion transmission between the handle 20 and the clamping member 30.

[0074] Of course, the transmission mechanism 40 can also take other forms, as long as it can convert the sliding of the handle 20 into the sliding of the clamping member 30. In some other embodiments, the transmission mechanism 40 may also include a linkage mechanism. The change in sliding direction is achieved by the rotation of the linkage. The specific composition of the linkage mechanism can be designed according to the actual situation. For example, the linkage mechanism may include a parallelogram linkage.

[0075] Furthermore, the transmission is achieved through the lead screw and nut mechanism 42, utilizing the threaded connection between the lead screw and nut mechanisms 42. The inclined surface of the thread allows the operator to perform the operation with less effort compared to other transmission methods, making operation easier (for example, using a linkage mechanism requires a larger applied force to ensure proper transmission after the force is distributed). At the same time, the lead screw and nut mechanism 42 has a relatively simple structure, occupies less space during installation, and has a more compact design.

[0076] In some embodiments, such as Figure 3 As shown, Figure 3 for Figure 1 The exploded view of the data acquisition device 100 shown indicates that the gear and rack mechanism 41 may include a transmission gear 411 and two transmission racks 412. The transmission gear 411 is rotatably connected to the mounting base 10. The two transmission racks 412 are slidably connected to the mounting base 10 and mesh with the transmission gear 411. One transmission rack 412 is connected to a clamping member 30.

[0077] Therefore, when the transmission gear 411 rotates, it can drive the two transmission racks 412 to slide relative to the mounting base 10, thereby realizing the movement of the two clamping parts 30 away from or towards each other. At this time, the gear and rack mechanism 41 has a relatively simple composition, occupies little space, and is easy to assemble.

[0078] The lead screw and nut mechanism 42 may include a lead screw 421 and a nut 422. The lead screw 421 is rotatably connected to the mounting base 10 and connected to the transmission gear 411. The nut 422 is sleeved on the lead screw 421 and connected to the handle 20. The nut 422 is used to slide along the extension direction of the lead screw 421 under the action of the handle 20, so as to drive the lead screw 421 to rotate relative to the mounting base 10.

[0079] Therefore, when the handle 20 slides relative to the mounting base 10, the nut 422 moves along with the handle 20 because the handle 20 is connected to the nut 422. At this time, the nut 422 moves relative to the lead screw 421. Because of the threaded connection between the nut 422 and the lead screw 421, the movement of the nut 422 relative to the lead screw 421 causes the lead screw 421 to rotate under the action of the threaded connection, thus converting the sliding of the handle 20 into the rotation of the lead screw 421. Simultaneously, because the lead screw 421 is connected to the transmission gear 411, the rotation of the lead screw 421 enables the transmission gear 411 to drive the transmission rack 412 to slide, thereby allowing the transmission rack 412 to drive the clamping member 30 to slide relative to the mounting base 10.

[0080] Of course, in other embodiments, the gear and rack mechanism 41 and the lead screw and nut mechanism 42 may also have other compositions. For example, the gear and rack mechanism 41 may also include two driven gears. The two driven gears mesh with the transmission gear 411 respectively, and each meshes with a transmission rack 412. In this way, the transmission gear 411 can drive the two driven gears to rotate, thereby using the two driven gears meshing with the two transmission racks 412 respectively to drive the transmission racks 412 to slide, ultimately realizing the movement of the two clamping members 30. At this time, by setting two driven gears, the position of the two transmission racks 412 can be conveniently arranged.

[0081] Furthermore, the specific type of lead screw 421 can be selected according to actual needs, and no further limitations are made here. For example, lead screw 421 can be a trapezoidal lead screw.

[0082] In some embodiments, such as Figure 3 As shown, the data acquisition device 100 also includes two housings 60. The housings 60 cover at least a portion of the gear and rack mechanism 41 and are connected to it. A clamping member 30 is disposed on the housing 60.

[0083] Therefore, the gear and rack mechanism 41 can drive the cover 60 to translate, thereby driving the clamping members 30 on the cover 60 to translate as well, realizing the relative approach or distance of the two clamping members 30. Simultaneously, since the cover 60 covers at least a portion of the gear and rack mechanism 41, it can protect at least a part of the gear and rack mechanism 41 and prevent any part of the gear and rack mechanism 41 from being exposed, ensuring a good appearance. The specific shape of the cover 60 is designed according to actual conditions, and this application does not further limit it.

[0084] Of course, in some other embodiments, the transmission rack 412 can also be directly connected to the clamping member 30. When the transmission rack 412 slides relative to the mounting base 10, it can directly drive the clamping member 30 to slide relative to the mounting base 10.

[0085] In some embodiments, such as Figure 3 As shown, the mounting base 10 has a groove 141. The data acquisition device 100 also includes two sliding members 70. The sliding members 70 are connected to the housing 60 and the transmission rack 412. The sliding members 70 are slidably connected to the groove 141.

[0086] Therefore, the sliding member 70 can be slidably connected to the mounting base 10 via the sliding groove 141. Since the sliding member 70 is connected to the transmission rack 412 and the cover 60, the transmission rack 412 can be slidably connected to the mounting base 10 via the sliding member 70, thereby ensuring that the transmission rack 412 can always mesh with the transmission gear 411.

[0087] For example, the mounting base 10 includes two fourth mounting members 14. The fourth mounting members 14 are connected to the second mounting members 12. The fourth mounting members 14 may have grooves 141 formed therein. Thus, a sliding connection between the slider 70 and the mounting base 10 can be achieved through the fourth mounting members 14. Of course, the second mounting member 12 may also have grooves 141 formed directly, and the slider 70 may also be directly slidably connected to the second mounting member 12.

[0088] Furthermore, by way of example, the fourth mounting member 14 can be detachably connected to the second mounting member 12. In this way, if the fourth mounting member 14 is damaged, the fourth mounting member 14 can be removed from the second mounting member 12 and a new fourth mounting member 14 can be replaced, avoiding the situation where the fourth mounting member 14 is unusable due to damage.

[0089] In other embodiments, the transmission rack 412 can also be directly slidably connected to the mounting base 10. In this way, the transmission gear 411 can slide directly relative to the mounting base 10, and the composition of the data acquisition device 100 can be relatively simple.

[0090] In some embodiments, such as Figure 3 As shown, the data acquisition device 100 may further include a connector 80. The connector 80 can be connected to the lead screw 421 and to the transmission gear 411. The transmission gear 411 can be connected to the lead screw 421 via the connector 80. Thus, connecting the transmission gear 411 and the lead screw 421 via the connector 80 can provide a certain degree of error compensation, reduce installation accuracy, and facilitate assembly.

[0091] Of course, in some other embodiments, the lead screw 421 and the transmission gear 411 can also be directly connected. In this case, the structure of the data acquisition device 100 is simpler and has fewer parts.

[0092] Furthermore, in order to achieve detachable connections between components, in some embodiments, such as Figure 3 As shown, the data acquisition device 100 may further include a first fastener 91 and a second fastener 92. The first fastener 91 and the second fastener 92 may be threaded together. The first fastener 91 and the second fastener 92 may be used to achieve a detachable connection between components.

[0093] For example, the first fastener 91 can be a screw, and the second fastener 92 can be a nut. The first fastener 91 and the second fastener 92 can connect the first mounting member 11 and the second mounting member 12. Alternatively, the first fastener 91 and the second fastener 92 can also be used to connect the fourth mounting member 14 and the second mounting member 12.

[0094] Of course, the components in the data acquisition device 100 can also be connected in other ways; the above is only an example and is not intended to limit the connection further. For example, the first mounting component 11 and the second mounting component 12 in the data acquisition device 100 can also be directly connected by a snap-fit ​​structure.

Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this application, and these modifications or substitutions should all be covered within the scope of protection of this application.
