[0053] The laser level instrument is used for projecting a laser line, can be applied to a vehicle calibration scene, is mounted on a crossbeam of a vehicle calibration device, and provides a reference line in a vehicle calibration application scene. The laser level instrument is internally provided with a pendulum, a laser emission assembly, and a driving assembly. The pendulum is mounted with the laser emission assembly, and the driving assembly is drivingly connected with the pendulum. The pendulum can swing or rotate under the driving of the driving assembly, so as to adjust the projection of the laser emission assembly. However, in the related art, the pendulum in the laser level instrument is easily affected by vibration or external force and collides with other components in the box body during non-use or transportation, resulting in damage of the pendulum or other components.

[0054] For a better understanding of the present application, reference will be made by way of example to the accompanying drawings in which: Figure 1 and Figure 2 In order to solve the above technical problems, in a first aspect, the embodiments of the present application provide a holding assembly applied to a laser level instrument.

[0055] In some embodiments, the laser level instrument 100 comprises a box body 10, a pendulum 20, and a holding assembly.

[0056] The working principle of the laser level instrument 100 provided by the embodiments of the present application is as follows: the laser level instrument 100 is provided with a holding assembly, the holding assembly is provided with a holding mechanism 30 and a sliding block 40 which cooperate with each other, and the holding of the pendulum 20 is realized. The sliding block 40 can slide relative to the box body 10 under the action of external force, when sliding to the locking position, the sliding block 40 drives the holding mechanism 30 to move and hold the pendulum 20, so that the pendulum 20 is fixed at a specific position in the box body 10, and collision of the pendulum 20 during transportation or vibration is prevented; when the sliding block 40 slides to the unlocking position, the sliding block 40 stops controlling the holding mechanism 30, and the holding mechanism 30 releases the pendulum 20, so that the pendulum 20 returns to a free state and can work normally. The structure setting makes the laser level instrument 100 be able to reliably lock the pendulum 20 when not in use, and avoids collision and damage of the pendulum 20 and other components.

[0057] It can be understood that the laser level 100 of the embodiment of the present application realizes effective protection of the pendulum body 20 in the process of non-use or transportation through the cooperation of the sliding block 40 and the holding mechanism 30, reduces the risk of damage caused by the collision of the pendulum body 20 and other components, and simultaneously improves the reliability and service life of the laser level 100.

[0058] In some embodiments, the holding mechanism 30 comprises two independent holding arms, the two independent holding arms are respectively hingedly installed in the box body 10, the two independent holding arms are oppositely arranged, the pendulum body 20 is arranged between the two independent holding arms, each independent holding arm can rotate relative to the pendulum body 20 about the hinged axis, the sliding block 40 is connected to each independent holding arm, the sliding block 40 is used to control the two independent holding arms to hold the pendulum body 20 when sliding to the locked position, and stop controlling the two independent holding arms when sliding to the unlocked position, so that the two independent holding arms release the pendulum body 20.

[0059] It can be understood that the two independent holding arms are adopted in the embodiment of the present application, and the two independent holding arms collectively hold the pendulum body 20 under the control of the sliding block 40, so that the pendulum body 20 can be uniformly and stably fixed in the box body 10 when subjected to vibration or external force.

[0060] Please refer to Figure 3 and Figure 4 In other embodiments, the holding mechanism 30 comprises a secondary holding arm 31 and a primary holding arm 32. The secondary holding arm 31 is hingedly installed in the box body 10, and the secondary holding arm 31 can rotate relative to the pendulum body 20 about the hinged axis of the secondary holding arm 31. The primary holding arm 32 is hingedly installed in the box body 10, the primary holding arm 32 is connected to the secondary holding arm 31, the primary holding arm 32 is connected to the sliding block 40 and controlled by the sliding block 40, the primary holding arm 32 and the secondary holding arm 31 are oppositely arranged, the pendulum body 20 is arranged between the primary holding arm 32 and the secondary holding arm 31, the primary holding arm 32 can rotate relative to the pendulum body 20 about the hinged axis of the primary holding arm 32 under the control of the sliding block 40, and the primary holding arm 32 drives the secondary holding arm 31 to hold the pendulum body 20, and the primary holding arm 32 drives the secondary holding arm 31 to release the pendulum body 20 under the stop control of the sliding block 40.

[0061] It can be understood that the design of the primary holding arm 32 and the secondary holding arm 31 enables the pendulum body 20 to be quickly and effectively fixed when subjected to vibration or external force, and guarantees the stability of the pendulum body 20. The secondary holding arm 31 and the primary holding arm 32 are respectively hingedly installed in the box body 10, and the primary holding arm 32 is connected to the secondary holding arm 31. The sliding block 40 controls the rotation of the primary holding arm 32, thereby driving the secondary holding arm 31 to hold or release the pendulum body 20. The present application realizes the quick fixing and releasing of the pendulum body 20 through the linkage of the primary holding arm 32 and the secondary holding arm 31, improves the operation convenience, and reduces the damage risk caused by vibration or external force.

[0062] Please refer to Figures 3 to 5In some embodiments, the box body 10 comprises a first hinge part 11 and a second hinge part 12, and the pendulum body 20 comprises a main shaft 21. The auxiliary clamping arm 31 comprises a first hinge matching part 311 and a first controlled part 312, the first hinge matching part 311 is hinged with the first hinge part 11, and the first controlled part 312 is used to rotate the auxiliary clamping arm 31 relative to the first hinge part 11 around the hinge axis of the first hinge matching part 311 and approach or move away from the main shaft 21 when linked.

[0063] The main clamping arm 32 comprises a second hinge matching part 321, a second controlled part 322, and a first linkage part 323, the second hinge matching part 321 is hinged with the second hinge part 12, the first linkage part 323 is connected with the second controlled part 322, the first linkage part 323 is connected with the first controlled part 312, the first linkage part 323 can follow the movement of the second controlled part 322 and link the first controlled part 312, the second controlled part 322 is connected with the sliding block 40, and the second controlled part 322 is used to rotate the main clamping arm 32 relative to the second hinge part 12 around the hinge axis of the second hinge matching part 321 until abutting against the main shaft 21 when controlled by the sliding block 40, and link the first controlled part 312 through the first linkage part 323 to make the auxiliary clamping arm 31 cooperate with the main clamping arm 32 to clamp the main shaft 21, and stop abutting against the main shaft 21 when the sliding block 40 stops sliding and controlling, and link the first controlled part 312 through the first linkage part 323 to make the auxiliary clamping arm 31 cooperate with the main clamping arm 32 to release the main shaft 21.

[0064] In the embodiments of the present application, the main shaft 21 specifically refers to the central shaft of the pendulum body 20 in the laser level 100, and the driving assembly on the laser level 100 can adjust the pendulum body 20 by driving the central shaft to make it swing or rotate.

[0065] It can be understood that the second controlled part 322 of the main clamping arm 32 drives the whole main clamping arm 32 to rotate around the second hinge matching part 321 under the control of the sliding block 40, and at the same time drives the first controlled part 312 of the auxiliary clamping arm 31 to move through the first linkage part 323, so that the auxiliary clamping arm 31 rotates around the first hinge matching part 311, and the two clamping arms move cooperatively until clamping the main shaft 21. The above-mentioned arrangement ensures the accuracy and synchronization of the clamping action, and reliably realizes the clamping of the main shaft 21.

[0066] In some embodiments, the main clamping arm 32 and the auxiliary clamping arm 31 are in a cross structure of stacking up and down, the auxiliary clamping arm 31 is located above the main clamping arm 32, 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, and the second controlled part comprises an abutting arc surface used to abut against the sliding block when the sliding block 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 substantially located on or close to the connection line of the first hinge part 11 and the second hinge part 12. Specifically, the first controlled part 312 is provided with a plug post, the first linkage part 323 is provided with a plug hole, the plug post is inserted into the plug hole, and a large gap is arranged between the plug hole and the plug post, so that the plug post has a certain rotation stroke in the plug hole, and the main clamping arm 32 and the auxiliary clamping arm 31 cannot be locked and cannot rotate. The first plug hole can rotate relative to the second hinge part 12 around the hinge axis of the second hinge fitting part 321, and the inner wall pushes the plug post to rotate relative to the first hinge part 11 around the hinge axis of the first hinge fitting part 311, so that the main clamping arm 32 and the auxiliary clamping arm 31 are close to each other and clamped to the main shaft 21.

[0068] Exemplarily, one of the first hinge part 11 and the first hinge fitting part 311 is a hinge hole, and the other is a hinge shaft, and the hinge is realized by the mutual connection of the hole and the shaft. Correspondingly, one of the second hinge part 12 and the second hinge fitting part 321 is a hinge hole, and the other is a hinge shaft, and the hinge is realized by the mutual connection of the hole and the shaft. In some embodiments, the first hinge fitting part 311 is located at one end of the auxiliary clamping arm 31, and the second hinge fitting part 321 is located at one end of the main clamping arm 32, thereby reducing the volume of the auxiliary clamping arm 31 and the main clamping arm 32, and facilitating the reduction of the occupied space of the clamping mechanism 30 in the box body 10.

[0069] In some embodiments, the auxiliary clamping arm 31 further comprises a first clamping arc segment 313 and at least one first top abutting part 314, and the at least one first top abutting part 314 is arranged on the first clamping arc segment 313 in the length direction of the first clamping arc segment 313.

[0070] The auxiliary clamping arm 31 further comprises a second clamping arc segment 324 and at least one second top abutting part 325, and the at least one second top abutting part 325 is arranged on the second clamping arc segment 324 in the length direction of the second clamping arc segment 324. The first clamping arc segment 313 and the second clamping arc segment 324 are oppositely arranged, and 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 top abutting part 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 to abut the main shaft 21 through the first top abutting part 314 when the main clamping arm 32 and the auxiliary clamping arm 31 clamp the main shaft 21.

[0071] It can be understood that the first clamping arc segment 313 and the second clamping arc segment 324 are arranged circumferentially, so that the main shaft 21 can be clamped from multiple directions, thereby ensuring the stability of the swing body 20.

[0072] More easily understood, the clamping effect is improved by arranging 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 arranged circumferentially along the main shaft 21 and have multiple abutting portions. When the clamping arm is closed, the abutting portions can abut against the main shaft 21 at multiple points at the same time, thereby increasing the contact area and dispersing the force. This not only ensures a stable clamping effect, but also avoids damage to the main shaft 21 caused by excessive local force. In addition, the multiple abutting portions can abut against 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 shaking slightly under the influence of vibration due to the gap between the main shaft 21 and any one 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 arranged in an arc shape on the corresponding clamping arms, and are oppositely arranged to surround the main shaft 21 of the swing body 20. The first abutting portion 314 and the second abutting portion 325 are protruding structures arranged on the corresponding clamping arc segments, and are distributed along the inner circumferential surface of the corresponding clamping arc segments. The first abutting portion 314 and the second abutting portion 325 are used for multi-point contact with the main shaft 21, 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 sliding block 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 locked position or an unlocked position under the action of external force.

[0075] The push button bracket 42 is arranged inside the box body 10, and the push button bracket 42 is connected with the push button 41. The push button bracket 42 is connected with the second controlled part 322, and the push button bracket 42 is used to follow the push button 41 to control the second controlled part 322 when sliding to the locked 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 unlocked 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 application realizes convenient control of the swing body 20 through cooperation of the push button 41 and the push button bracket 42. The push button 41 is installed on the box body 10 for convenient operation, and can be slid to the locking position or the unlocking position through external pushing force. The push button bracket 42 is connected with the push button 41 and extends to the inside of the box body 10, and is connected with the second controlled part 322 of the main clamping arm 32. When the push button 41 slides, the push button bracket 42 is driven to move, so as to control the main clamping arm 32 to rotate and drive the auxiliary clamping arm 31, and finally realize clamping or releasing of the main shaft 21. The embodiment of the application realizes effective connection of the inner and outer structures, is convenient to operate, reliable in force transmission, and improves the use performance of the whole mechanism.

[0077] In some embodiments, the second controlled part 322 is a part of the main clamping arm 32 directly controlled by the slider 40, and is configured to be matched with the abutting inclined surface 421 of the push button bracket 42. For example, the second controlled part 322 is a protruding structure, and is configured with an abutting arc surface.

[0078] Please refer to Figure 5 In some embodiments, the push button bracket 42 includes the abutting inclined surface 421, which is positioned with the second controlled part 322. When the push button bracket 42 slides to the locking position, the abutting inclined surface 421 can abut and push the second controlled part 322, so as to control the main clamping arm 32 and the auxiliary clamping arm 31 to clamp the main shaft 21 by controlling the second controlled part 322. When the push button bracket 42 slides to the unlocking position, the abutting inclined surface 421 abuts or separates from the second controlled part 322, so as to make the main clamping arm 32 and the auxiliary clamping arm 31 release the main shaft 21 by stopping controlling the second controlled part 322.

[0079] It can be understood that, in the embodiment of the application, the abutting inclined surface 421 on the push button bracket 42 cooperates with the second controlled part 322, and the abutting inclined surface 421 can push the second controlled part 322 to rotate. When the push button bracket 42 slides to the locking position, the abutting inclined surface 421 gradually pushes the second controlled part 322, so that the main clamping arm 32 stably rotates 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 separates from the second controlled part 322, so that the clamping mechanism 30 is stably released. In the embodiment of the application, the abutting inclined surface 421 pushes the second controlled part 322, which not only ensures the smoothness of the locking and unlocking process, but also reduces the impact and wear between mechanisms, prolongs the service life of the components.

[0080] Please refer to Figure 6 and Figure 7In some embodiments, the box body 10 is provided with a first clamping groove 13 and a second clamping groove 14, which are respectively arranged at different positions on the sliding stroke of the push button support 42. The push button support 42 comprises a clamping portion 422, which can be clamped with the first clamping groove 13 when the push button support 42 slides to the locked position, and can be clamped with the second clamping groove 14 when the push button support 42 slides to the unlocked position.

[0081] It can be understood that, by arranging the first clamping groove 13 and the second clamping groove 14 on the box body 10, and arranging the corresponding clamping portion 422 on the push button support 42, a reliable position locking is formed. When the push button support 42 slides to the locked position or the unlocked position, the clamping portion 422 will be clamped with the corresponding clamping groove, respectively, to generate a clear in-place feeling and prevent the push button 41 from moving accidentally. This double-position clamping design not only provides clear operation feedback and enhances the user experience, but also effectively prevents the push button 41 and the push button support 42 from moving accidentally during use, thereby improving the reliability and safety of the entire holding mechanism 30.

[0082] Please refer to Figure 1 and Figure 2 In a second aspect, the embodiments of the present application also provide a laser level 100, which comprises a box body 10, a pendulum body 20, a laser emitting assembly, a driving assembly, and the holding assembly described above. The pendulum body 10 is installed in the box body. The laser emitting assembly is installed on the pendulum body 10, and is used to project a laser line outward. The driving assembly is installed in the box body 10, and is drivingly connected with the pendulum body 20. The driving assembly is used to drive the pendulum body 20 to adjust the projection direction of the laser emitting assembly. The holding assembly is connected with the pendulum body, and can hold the pendulum body.

[0083] It can be understood that the laser level 100 of the embodiments of the present application is provided with the holding assembly, which realizes the locking protection of the pendulum body 20 by arranging the holding mechanism 30 and the sliding block 40 which cooperate with each other. The sliding block 20 can slide relative to the box body 10 under the action of an external force. When sliding to the locked position, the sliding block 40 drives the holding mechanism 30 to move and hold the pendulum body 20, so that the pendulum body 20 is fixed at a specific position inside the box body 10, and collision of the pendulum body 20 during transportation or vibration is prevented. When the sliding block 40 slides to the unlocked position, the sliding block 40 stops controlling the holding mechanism 30, and the holding mechanism 30 releases the pendulum body 20, so that the pendulum body 20 returns to a free state and can work normally. The structure arrangement enables the laser level 100 to reliably lock the pendulum body 20 when not in use, thereby avoiding collision and damage of the pendulum body 20 with other components.

[0084] The laser emitting assembly comprises at least one laser emitter installed on the pendulum body 20. The driving assembly can drive the pendulum body 20 to swing or rotate, so as to change the emission direction of the laser emitter.

[0085] Referring to Figure 6 and Figure 8 In some embodiments, the laser level 100 further comprises a micro switch 50, a power supply and a circuit board, which are all arranged in the box body 10, the micro switch 50 is electrically connected with the power supply and the circuit board respectively, and the micro switch 50 keeps a normal open state.

[0086] The sliding block 40 comprises a second linkage part 423, the micro switch 50 is arranged on the sliding stroke of the second linkage part 423, and the second linkage part 423 is used to connect and control the micro switch 50 to close when the sliding block 40 slides to the unlocking position, so as to make the power supply supply power to the circuit board, and stop controlling the micro switch 50 when the sliding block 40 slides to the locking position, so as to make the micro switch 50 return to the normal open state.

[0087] It can be understood that, by integrating the micro switch 50, the power supply and the circuit board in the box body 10 and linking the second linkage part 423 of the sliding block 40, the linkage of the locking mechanism and the power supply control is realized. The micro switch 50 is normally open, and only when the sliding block 40 slides to the unlocking position, the second linkage part 423 triggers the micro switch 50 to close, so as to make the power supply supply power to the circuit board; when the sliding block 40 returns to the locking position, the micro switch 50 is automatically opened. The mechanical locking and the power supply control are organically combined in the embodiments of the present application, which can not only prevent accidental power-on in the locked state, but also automatically turn on the power supply when unlocking and using, thereby improving the safety and use convenience of the equipment.

[0088] In some embodiments, the micro switch 50 comprises 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 abut each other, the micro switch 50 is in a closed state, and 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 support 42. Specifically, the second linkage part 423 is a push block, which is used to abut the switch spring 51 when the sliding block 40 slides to the unlocking position, so as to make the switch spring 51 abut the switch contact 52, and stop abutting the switch spring 51 when the sliding block 40 slides to the locking position, so as to make the switch spring 51 return to deformation and separate from the switch contact 52.

[0089] It can be understood that the combination of the switch spring 51 and the switch contact 52 is designed to cooperate with the push block on the sliding block 40 to form a reliable circuit switching mechanism. When the sliding block 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 loop; when the sliding block 40 returns to the locking position, the switch spring 51 restores the deformation under the action of its own elasticity and separates from the switch contact 52, ensuring that the circuit is disconnected. The application adopts the electrical connection triggering mode 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 gradual pressing mode of the push block also effectively reduces the instantaneous impact of the electrical switch, prolonging the service life of the micro switch 50.

[0090] Please refer to Figure 1 and Figure 9 In a third aspect, the calibration device 1000 provided by the embodiment of the application includes a base 200, a main frame 300, a cross beam 400, and the laser level 100 of the above-mentioned embodiment. The main frame 300 is vertically fixed on the base 200, and the cross beam 400 is horizontally installed on the top of the main frame 300, forming a stable frame structure. The laser level 100 is detachably installed on the cross beam 400 through a quick release interface or a magnetic adsorption assembly, which is convenient for adjusting the installation position or replacing different models of laser levels according to actual calibration needs.

[0091] In the process of calibrating the automobile, the laser level 100 projects a high-precision laser line through its laser emitting assembly as a reference for vehicle calibration. When the calibration device 1000 is in a working state, the user slides the sliding block 40 to the unlocking position, at which time the holding mechanism 30 releases the swing body 20, and the driving assembly drives the swing body 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 sliding block 40 triggers the micro switch 50 to close, and the circuit board is powered on to start the laser emission and automatic calibration function. When the calibration is completed or the device needs to be transported, the user pushes the sliding block 40 to the locking position, and the holding mechanism 30 synchronously clamps the main shaft 21 of the swing body 20 to prevent the swing body 20 from colliding with the inside of the box body 10 due to vibration; at the same time, the micro switch 50 is disconnected to cut off the power supply to save energy and ensure safety.

[0092] In a fourth aspect, the embodiment of the application also provides a calibration system, which includes the calibration device 1000 in the above-mentioned embodiment and a diagnostic instrument, and the diagnostic instrument is in communication connection with the calibration device 1000.

[0093] The diagnostic instrument can be a tablet diagnostic instrument for easy carrying and transportation. Optionally, a visual camera is arranged on the cross beam of the calibration device 1000, and the visual camera is in communication connection with the diagnostic instrument, and the diagnostic instrument can be used to receive vehicle image data photographed by the visual camera.

[0094] Optionally, the calibration system can also include calibration elements such as targets, mirrors, etc., which can be mounted on the cross beam.
