In addition, the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0052] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0053] The laser level is used to project a laser line and can be applied to automobile calibration scenarios. It is mounted on the crossbeam of the automobile calibration device to provide a reference line in application scenarios such as automobile calibration. The laser level is internally provided with a pendulum, a laser emission component and a drive component. The pendulum is equipped with a laser emission component, and the drive component drives the pendulum. The pendulum can swing or rotate under the drive of the drive component to adjust the projected laser line of the laser emission component. However, when the laser level in the related technical content is not in use or during transportation, the internal pendulum is easily affected by vibration or external force and collides with other components inside the box, causing damage to the pendulum or other components.

[0054] Please also read Figure 1 and Figure 2 In order to solve the above technical problems, in a first aspect, an embodiment of the present application provides a clamping component applied to a laser level.

[0055] In some embodiments, the laser level 100 includes a box body 10, a pendulum body 20 and a clamping assembly. The clamping assembly includes a clamping mechanism 30 and a slider 40. The pendulum body 20 is installed in the box body 10, the clamping mechanism 30 is installed in the box body 10, the clamping mechanism 30 can clamp the pendulum body 20, the slider 40 is installed on the box body 10 and connected to the clamping mechanism 30 in the box body 10, the slider 40 can slide relative to the box body 10, and the sliding stroke of the slider 40 includes a locking position and an unlocking position. The slider 40 is used to control the clamping mechanism 30 to clamp the pendulum body 20 when sliding to the locking position, and stop controlling the clamping mechanism 30 when sliding to the unlocking position, so that the clamping mechanism 30 releases the pendulum body 20.

[0056] The working principle of the laser level 100 provided in the embodiment of the present application is as follows: the laser level 100 is provided with a clamping assembly, and the clamping assembly realizes locking protection of the pendulum 20 by providing a clamping mechanism 30 and a slider 40 that cooperate with each other. The slider 40 can slide relative to the box body 10 under the action of an external force. When sliding to the locking position, the slider 40 drives the clamping mechanism 30 to move and clamp the pendulum 20, so that the pendulum 20 is fixed at a specific position inside the box body 10 to prevent the pendulum 20 from colliding during transportation or vibration; when the slider 40 slides to the unlocking position, the slider 40 stops controlling the clamping mechanism 30, and the clamping mechanism 30 then releases the pendulum 20, so that the pendulum 20 returns to a free state and can work normally. This structural setting enables the laser level 100 to reliably lock the pendulum 20 when not in use, avoiding collision damage between the pendulum 20 and other components.

[0057] It can be understood that the laser level 100 of the embodiment of the present application achieves effective protection for the pendulum 20 when not in use or in transportation through the cooperation of the slider 40 and the clamping mechanism 30, thereby reducing the risk of damage caused by collision between the pendulum 20 and other components. At the same time, it is simple and convenient to operate, thereby improving the reliability and service life of the laser level 100.

[0058] In some embodiments, the clamping mechanism 30 includes two independent clamping arms, which are respectively hingedly installed in the box body 10, and the two independent clamping arms are arranged opposite to each other. The pendulum body 20 is arranged between the two independent clamping arms, and each independent clamping arm can rotate around the hinge axis relative to the pendulum body 20. The slider 40 is respectively connected to each independent clamping arm, and the slider 40 is used to control the two independent clamping arms to clamp the pendulum body 20 when sliding to the locking position, and stop controlling the two independent clamping arms when sliding to the unlocking position, so that the two independent clamping arms release the pendulum body 20.

[0059] It can be understood that the embodiment of the present application adopts two independent clamping arms, which jointly clamp the pendulum body 20 under the control of the slider 40, so that the pendulum body 20 can be evenly and stably fixed in the box body 10 when subjected to vibration or external force.

[0060] Please also read Figure 3 and Figure 4 In other embodiments, the clamping mechanism 30 includes a secondary clamping arm 31 and a main clamping arm 32. The secondary clamping arm 31 is hingedly installed in the box body 10, and the secondary clamping arm 31 can rotate relative to the pendulum body 20 around its own hinge axis. The main clamping arm 32 is hingedly installed in the box body 10, the main clamping arm 32 is connected to the secondary clamping arm 31, the main clamping arm 32 is connected to the slider 40 and is controlled by the slider 40, the main clamping arm 32 and the secondary clamping arm 31 are arranged opposite to each other, and the pendulum body 20 is arranged between the main clamping arm 32 and the secondary clamping arm 31, the main clamping arm 32 can rotate relative to the pendulum body 20 around its own hinge axis under the control of the slider 40, and link the secondary clamping arm 31 to clamp the pendulum body 20, and link the secondary clamping arm 31 to release the pendulum body 20 under the control of the slider 40.

[0061] It can be understood that the design of the main clamping arm 32 and the auxiliary clamping arm 31 enables the pendulum body 20 to be quickly and effectively fixed when subjected to vibration or external force, thereby ensuring the stability of the pendulum body 20. The auxiliary clamping arm 31 and the main clamping arm 32 are respectively hinged in the box body 10, and the main clamping arm 32 is connected to the auxiliary clamping arm 31. The slider 40 controls the rotation of the main clamping arm 32, thereby linking the auxiliary clamping arm 31 to clamp or release the pendulum body 20. The present invention realizes the rapid fixation and release of the pendulum body 20 through the linkage of the main clamping arm 32 and the auxiliary clamping arm 31, improves the convenience of operation, and reduces the risk of damage caused by vibration or external force.

[0062] Please also read Figures 3 to 5In some embodiments, the box body 10 includes a first hinged portion 11 and a second hinged portion 12, and the swing body 20 includes a main shaft 21. The secondary clasping arm 31 includes a first hinged matching portion 311 and a first controlled portion 312, the first hinged matching portion 311 is hinged to the first hinged portion 11, and the first controlled portion 312 is used to make the secondary clasping arm 31 rotate relative to the first hinged portion 11 around the hinge axis of the first hinged matching portion 311 and approach or move away from the main shaft 21 when being linked.

[0063] The main holding arm 32 includes a second hinged matching portion 321, a second controlled portion 322 and a first linkage portion 323. The second hinged matching portion 321 is hinged to the second hinged portion 12, the first linkage portion 323 is connected to the second controlled portion 322, the first linkage portion 323 is connected to the first controlled portion 312, the first linkage portion 323 can follow the movement of the second controlled portion 322 and link the first controlled portion 312, the second controlled portion 322 is connected to the slider 40, and the second controlled portion 322 is used to be slidable. When the block 40 is controlled, the main clamping arm 32 rotates around the hinge axis of the second hinged matching part 321 relative to the second hinged part 12 until it hits the main shaft 21, and the first controlled part 312 is linked through the first linkage part 323, so that the auxiliary clamping arm 31 cooperates with the main clamping arm 32 to clamp the main shaft 21; and when the slider 40 stops sliding, it stops hitting the main shaft 21, and the first controlled part 312 is linked through the first linkage part 323, so that the auxiliary clamping arm 31 cooperates with the main clamping arm 32 to release the main shaft 21.

[0064] The main axis 21 referred to in the embodiment of the present application is specifically the central axis of the pendulum 20 in the laser level 100. The driving component on the laser level 100 can adjust the pendulum 20 by driving the central axis to make it swing or rotate.

[0065] It can be understood that the second controlled portion 322 of the main clasping arm 32 drives the entire main clasping arm 32 to rotate around the second hinged matching portion 321 under the control of the slider 40, and at the same time drives the first controlled portion 312 of the auxiliary clasping arm 31 to move through the first linkage portion 323, so that the auxiliary clasping arm 31 rotates around the first hinged matching portion 311, and the two clasping arms move in coordination until they clasp the main shaft 21. The embodiment of the present application ensures the accuracy and synchronization of the clasping action through the above-mentioned arrangement, and reliably realizes the clasping of the main shaft 21.

[0066] In some embodiments, the main clasping arm 32 and the auxiliary clasping arm 31 are cross structures stacked up and down, the auxiliary clasping arm 31 is located above the main clasping arm 32, and the connection position of the first controlled part 312 and the first linkage part 323 is located on the center line of the cross structure and is farther away from the main shaft 21 than the intersection. The second controlled part is located on the center line of the cross structure and is farther away from the main shaft than the first linkage part. The second controlled part includes an abutting arc surface, which is used to abut the slider when the slider slides to the locking position.

[0067] Exemplarily, the connection position of the first controlled part 312 and the first linkage part 323 is located between the first hinge part 11 and the second hinge part 12, and is approximately located on or close to the connection line between the first hinge part 11 and the second hinge part 12. Specifically, the first controlled part 312 is provided with a plug column, and the first linkage part 323 is provided with a socket. The plug column is inserted into the socket, and a large gap is configured between the socket and the plug column, so that the plug column has a certain rotation stroke in the socket, which can prevent the main clamping arm 32 and the auxiliary clamping arm 31 from being locked with each other and unable to rotate. The first socket can follow the second controlled part 322 to rotate relative to the second hinge part 12 around the hinge axis of the second hinge matching part 321, and push the plug column to rotate relative to the first hinge part 11 around the hinge axis of the first hinge matching part 311 through the inner wall, so that the main clamping arm 32 and the auxiliary clamping arm 31 are close to each other and clamp the main shaft 21.

[0068] As another example, one of the first hinged portion 11 and the first hinged matching portion 311 is a hinged hole, and the other is a hinged shaft, and the two are hinged by the mutual connection of the hole and the shaft. Correspondingly, one of the second hinged portion 12 and the second hinged matching portion 321 is a hinged hole, and the other is a hinged shaft, and the two are hinged by the mutual connection of the hole and the shaft. In some embodiments, the first hinged matching portion 311 is located at one end of the secondary clamping arm 31, and the second hinged matching portion 321 is located at one end of the main clamping arm 32, thereby reducing the volume of the secondary clamping arm 31 and the main clamping arm 32, which is conducive to reducing the space occupied by the clamping mechanism 30 in the box body 10.

[0069] In some embodiments, the auxiliary clamping arm 31 further includes a first clamping arc segment 313 and at least one first abutting portion 314 , and the at least one first abutting portion 314 is arranged on the first clamping arc segment 313 at intervals along the circumference direction of the first clamping arc segment 313 .

[0070] The auxiliary clamping arm 31 also includes a second clamping arc segment 324 and at least one second abutting portion 325. The at least one second abutting portion 325 is arranged on the second clamping arc segment 324 at intervals along the circumference direction of the second clamping arc segment 324. The first clamping arc segment 313 and the second clamping arc segment 324 are arranged relatively to each other. The main shaft 21 is arranged between the first clamping arc segment 313 and the second clamping arc segment 324. Each of the first clamping arc segment 313 and the second clamping arc segment 324 circumferentially surrounds the main shaft 21. The second clamping arc segment 324 is used to abut the main shaft 21 through the second abutting portion 325 when the main clamping arm 32 and the auxiliary clamping arm 31 clamp the main shaft 21. The first clamping arc segment 313 is used to cooperate with the second clamping arc segment 324 when the main clamping arm 32 and the auxiliary clamping arm 31 clamp the main shaft 21, and abut the main shaft 21 through the first abutting portion 314.

[0071] It can be understood that the embodiment of the present application can clamp the main shaft 21 from multiple directions through the circumferential arrangement of the first clamping arc segment 313 and the second clamping arc segment 324, thereby ensuring the stability of the pendulum 20.

[0072] It is easier to understand that the embodiment of the present application improves the clamping effect by providing the structure of the clamping arc segment and the abutting portion on the clamping arm. The first clamping arc segment 313 and the second clamping arc segment 324 are provided with multiple abutting portions along the circumference of the main shaft 21. When the clamping arm is closed, these abutting portions can abut the main shaft 21 at multiple points at the same time, increasing the contact area and dispersing the force, which not only ensures a stable clamping effect, but also avoids damage to the main shaft 21 caused by excessive local force. In addition, multiple abutting portions can abut the circumferential surface of the main shaft 21 from different directions, effectively clamping the main shaft 21, and avoiding the main shaft 21 from still having a small shake under the influence of vibration due to the gap between the main shaft 21 and any of the first clamping arc segment 313 and the second clamping arc segment 324.

[0073] Specifically, the first clamping arc segment 313 and the second clamping arc segment 324 are arc-shaped structures, respectively arranged on the corresponding clamping arms, which are arranged opposite to each other and together surround the main shaft 21 of the pendulum body 20. The first abutting portion 314 and the second abutting portion 325 are protruding structures respectively arranged on the corresponding clamping arc segments, and are spaced apart along the inner circumferential surface of the corresponding clamping arc segments, and are used to contact the main shaft 21 at multiple points, provide a more stable fixing effect, and avoid local damage to the main shaft 21 by dispersing the force points.

[0074] In some embodiments, the slider 40 includes a push button 41 and a push button bracket 42. The push button 41 is mounted on the box body 10, and the push button 41 is used to slide to a locking position or an unlocking position under the action of an external thrust.

[0075] The push button bracket 42 is arranged inside the box body 10, the push button bracket 42 is connected to the push button 41, and the push button bracket 42 is connected to the second controlled part 322. The push button bracket 42 is used to follow the push button 41, and control the second controlled part 322 when sliding to the locking position so that the main clamping arm 32 and the auxiliary clamping arm 31 clamp the main shaft 21, and stop controlling the second controlled part 322 when sliding to the unlocking position so that the main clamping arm 32 and the auxiliary clamping arm 31 release the main shaft 21.

[0076] It can be understood that the embodiment of the present application realizes convenient control of the pendulum body 20 through the cooperation of the push button 41 and the push button bracket 42. The push button 41 is installed on the box body 10 for easy operation, and the push button 41 can be slid to the locked position or unlocked position through external thrust. The push button bracket 42 is connected to the push button 41 and extends to the inside of the box body 10, and is connected to the second controlled part 322 of the main clamping arm 32. When the push button 41 slides, it drives the push button bracket 42 to move, thereby controlling the rotation of the main clamping arm 32 and linking the secondary clamping arm 31, and finally realizing the clamping or loosening of the main shaft 21. The embodiment of the present application realizes the effective connection of the internal and external structures, is easy to operate and has reliable force transmission, and improves the performance of the entire mechanism.

[0077] In some embodiments, the second controlled portion 322 is the portion of the main clamping arm 32 that is directly controlled by the slider 40 and is configured to match the abutment slope 421 of the push button bracket 42. Exemplarily, the second controlled portion 322 is a protruding structure and is configured with an abutment arc surface.

[0078] Please review Figure 5 In some embodiments, the push button bracket 42 includes an abutment slope 421, which is aligned with the second controlled part 322. The abutment slope 421 can abut and push the second controlled part 322 when the push button bracket 42 slides to the locking position, so as to control the main clamping arm 32 and the linked auxiliary clamping arm 31 to clamp the main shaft 21 by controlling the second controlled part 322, and abut or disengage from the second controlled part 322 when the push button bracket 42 slides to the unlocking position, so as to stop controlling the second controlled part 322, so that the main clamping arm 32 and the auxiliary clamping arm 31 release the main shaft 21.

[0079] It can be understood that the embodiment of the present application can push the second controlled part 322 to rotate by setting an abutting inclined surface 421 on the push button bracket 42 to cooperate with the second controlled part 322. When the push button bracket 42 slides to the locking position, the abutting inclined surface 421 will gradually push the second controlled part 322, so that the main clamping arm 32 rotates smoothly and drives the auxiliary clamping arm 31 until the main shaft 21 is completely clamped; when the push button bracket 42 slides to the unlocking position, the abutting inclined surface 421 gradually disengages from the second controlled part 322, so that the clamping mechanism 30 is released smoothly. The embodiment of the present application pushes the second controlled matching part 322 by the abutting inclined surface 421, which not only ensures the smoothness of the locking and unlocking process, but also reduces the impact wear between the mechanisms and prolongs the service life of the components.

[0080] Please also read Figure 6 and Figure 7In some embodiments, the box body 10 is provided with a first card slot 13 and a second card slot 14, and the first card slot 13 and the second card slot 14 are respectively arranged at different positions on the sliding stroke of the button bracket 42, and the button bracket 42 includes a card connecting portion 422, and the card connecting portion 422 can be carded with the first card slot 13 when the button bracket 42 slides to the locking position, and carded with the second card slot 14 when the button bracket 42 slides to the unlocking position.

[0081] It can be understood that the embodiment of the present application forms a reliable position lock by providing the first card slot 13 and the second card slot 14 on the box body 10 and providing the corresponding card connection portion 422 on the push button bracket 42. When the push button bracket 42 slides to the locked position or the unlocked position, the card connection portion 422 will respectively engage with the corresponding card slot, produce a clear sense of being in place, and prevent the push button 41 from accidentally moving. This dual-position card connection design not only provides clear operational feedback and enhances the user experience, but also effectively prevents the push button 41 and the push button bracket 42 from accidentally moving during use, thereby improving the reliability and safety of the entire clamping mechanism 30.

[0082] Please review Figure 1 and Figure 2 In the second aspect, the embodiment of the present application further provides a laser level 100, including a box body 10, a pendulum body 20, a laser emission component, a driving component and the above-mentioned clamping component. The pendulum body 10 is installed in the box body. The laser emission component is installed on the pendulum body 10, and the laser emission component is used to project a laser line outward. The driving component is installed in the box body 10, and the driving component drives the pendulum body 20, and the driving component is used to drive the pendulum body 20 to adjust the projection direction of the laser emission component. The clamping component is connected to the pendulum body, and the clamping component can clamp the pendulum body.

[0083] It can be understood that the laser level 100 of the embodiment of the present application is provided with a clamping assembly, which realizes locking protection of the pendulum 20 by providing a clamping mechanism 30 and a slider 40 that cooperate with each other. The slider 20 can slide relative to the box body 10 under the action of an external force. When sliding to the locking position, the slider 40 drives the clamping mechanism 30 to move and clamp the pendulum 20, so that the pendulum 20 is fixed at a specific position inside the box body 10 to prevent the pendulum 20 from colliding during transportation or vibration; when the slider 40 slides to the unlocking position, the slider 40 stops controlling the clamping mechanism 30, and the clamping mechanism 30 then releases the pendulum 20, so that the pendulum 20 returns to a free state and can work normally. This structural setting enables the laser level 100 to reliably lock the pendulum 20 when not in use, avoiding collision damage between the pendulum 20 and other components.

[0084] The laser emission component includes at least one laser emitter installed on the pendulum body 20, and the driving component can drive the pendulum body 20 to swing or rotate, thereby changing the emission direction of the laser emitter.

[0085] See also Figure 6 and Figure 8 In some embodiments, the laser level 100 further includes a micro switch 50, a power supply and a circuit board. The micro switch 50, the power supply and the circuit board are all arranged in the box body 10. The micro switch 50 is electrically connected to the power supply and the circuit board respectively, and the micro switch 50 remains in a normally off state.

[0086] The slider 40 includes a second linkage portion 423, and the micro switch 50 is arranged on the sliding stroke of the second linkage portion 423. The second linkage portion 423 is used to connect with the micro switch 50 and control the micro switch 50 to close when the slider 40 slides to the unlocking position, so that the power supply supplies power to the circuit board, and when the slider 40 slides to the locking position, stop controlling the micro switch 50 so that the micro switch 50 returns to the normally off state.

[0087] It can be understood that the embodiment of the present application realizes the linkage between the locking mechanism and the power control by integrating the micro switch 50, the power supply and the circuit board in the box body 10 and linking with the second linkage part 423 of the slider 40. The micro switch 50 is normally disconnected, and only when the slider 40 slides to the unlocked position, the second linkage part 423 will trigger the micro switch 50 to close, so that the power supply supplies power to the circuit board; when the slider 40 returns to the locked position, the micro switch 50 is automatically disconnected. The embodiment of the present application organically combines mechanical locking with power control, which can not only prevent accidental power-on in the locked state, but also automatically turn on the power when unlocked for use, thereby improving the safety and convenience of the device.

[0088] In some embodiments, the micro switch 50 includes a switch spring 51 and a switch contact 52. When the switch spring 51 and the switch contact 52 are separated from each other, the micro switch 50 is in an open state. When the switch spring 51 and the switch contact 52 are in contact with each other, the micro switch 50 is in a closed state. The switch spring 51 is arranged on the sliding stroke of the second linkage part 423. Exemplarily, the second linkage part 423 is arranged on the push button bracket 42. Specifically, the second linkage part 423 is a push block, which is used to push against the switch spring 51 when the slider 40 slides to the unlocking position, so that the switch spring 51 abuts against the switch contact 52, and when the slider 40 slides to the locking position, the push block stops pushing against the switch spring 51, so that the switch spring 51 recovers its deformation and is separated from the switch contact 52.

[0089] It can be understood that the embodiment of the present application adopts a combination design of the switch spring 51 and the switch contact 52, which cooperates with the push block on the slider 40 to form a reliable circuit switch mechanism. When the slider 40 slides to the unlocking position, the push block will push against the switch spring 51 to make it contact with the switch contact 52, forming a closed circuit; when the slider 40 returns to the locking position, the switch spring 51 restores its deformation under its own elasticity and disengages from the switch contact 52, ensuring that the circuit is disconnected. The embodiment of the present application adopts an electrical connection triggering method of the switch spring 51 and the switch contact 52, which not only provides stable and reliable circuit control, but also has good durability. At the same time, the progressive pressing method of the push block also effectively reduces the instantaneous impact of the electrical switch and extends the service life of the micro switch 50.

[0090] See also Figure 1 and Fig. 9 In the third aspect, the calibration device 1000 provided in the embodiment of the present application includes a base 200, a main frame 300, a crossbeam 400 and the laser level 100 of the above embodiment. The main frame 300 is vertically fixed on the base 200, and the crossbeam 400 is horizontally installed on the top of the main frame 300 to form a stable frame structure. The laser level 100 is detachably installed on the crossbeam 400 through a quick release interface or a magnetic adsorption component, which is convenient for adjusting its installation position or replacing different models of laser levels according to actual calibration requirements.

[0091] During the vehicle calibration process, the laser level 100 projects a high-precision laser line through its laser emission component as a reference for vehicle calibration. When the calibration device 1000 is in working condition, the user slides the slider 40 to the unlocked position, at which time the clamping mechanism 30 releases the pendulum 20, and the driving component drives the pendulum 20 to swing freely to dynamically adjust the projection angle of the laser line. At the same time, the second linkage part 423 of the slider 40 triggers the micro switch 50 to close, and the circuit board is powered on to start the laser emission and automatic calibration functions. When the calibration is completed or the equipment needs to be transported, the user pushes the slider 40 to the locked position, and the clamping mechanism 30 synchronously clamps the main shaft 21 of the pendulum 20 to prevent vibration from causing the pendulum 20 to collide with the inside of the box body 10; at the same time, the micro switch 50 is disconnected, cutting off the power supply to save energy and ensure safety.

[0092] In a fourth aspect, an embodiment of the present application further provides a calibration system, which includes the calibration device 1000 in the above embodiment and a diagnostic instrument, and the diagnostic instrument is communicatively connected to the calibration device 1000.

[0093] The diagnostic instrument can be a flat-panel diagnostic instrument for easy portability and transportation. Optionally, a visual camera is provided on the crossbeam of the calibration device 1000, and the visual camera is communicatively connected with the diagnostic instrument, and the diagnostic instrument can be used to receive vehicle image data captured by the visual camera.
