Clamping components, laser level, calibration equipment and calibration system
[0001] This application claims priority to Chinese Patent Application No. 2025101169852, filed on January 24, 2025, entitled "Holding Component, Laser Level, Calibration Equipment and Calibration System", the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of automotive calibration device technology, and more particularly to clamping components, laser levels, calibration equipment, and calibration systems. Background Technology
[0003] A laser level is a device commonly used to project laser lines, widely applied in scenarios requiring precise reference lines, such as automotive calibration. These devices provide users with intuitive alignment or measurement references by emitting laser lines. However, when not in use or during transportation, the internal pendulum is susceptible to vibration or external impact. Because the pendulum typically has a certain gap from other internal components, when the laser level encounters vibration or external impact, the pendulum may swing within the housing, colliding with other components and causing damage to the pendulum or other internal parts. Summary of the Invention
[0004] One objective of this application is to provide a clamping component, a laser level, a calibration device, and a calibration system to solve the technical problem that laser levels are easily damaged by abnormal swinging of the pendulum when not in use or during transportation.
[0005] In a first aspect, embodiments of this application provide a clamping assembly applied to a laser level, the laser level including a pendulum body and a housing, the pendulum body being mounted within the housing, and the pendulum body clamping assembly comprising:
[0006] A clamping mechanism, installed inside the housing, capable of clamping the swing body; and
[0007] A slider is mounted on the box and connected to the clamping mechanism inside the box. The slider is slidable relative to the box. The sliding stroke of the slider includes a locked position and an unlocked position. The slider is used to control the clamping mechanism to clamp the swing body when sliding to the locked position, and to stop controlling the clamping mechanism when sliding to the unlocked position, so that the clamping mechanism releases the swing body.
[0008] Optionally, the clamping mechanism includes:
[0009] A secondary clamping arm, hingedly mounted within the housing, is rotatable relative to the pendulum body about its own hinge axis; and
[0010] A main clamping arm is hingedly mounted inside the housing and connected to a secondary clamping arm. The main clamping arm is connected to and controlled by a slider. The main clamping arm and the secondary clamping arm are arranged opposite to each other. A swing body is disposed between the main clamping arm and the secondary clamping arm. The main clamping arm can rotate relative to the swing body around its own hinge axis under the control of the slider, and can also clamp the swing body by linking the secondary clamping arm with the slider, and can also release the swing body by linking the secondary clamping arm with the slider when the slider stops.
[0011] Optionally, the box body includes a first hinge portion and a second hinge portion, and the swing body includes a main shaft;
[0012] The auxiliary clamping arm includes a first hinged engagement portion and a first controlled portion. The first hinged engagement portion and the first hinge portion are hinged together. The first controlled portion is used to cause the auxiliary clamping arm to rotate relative to the first hinge portion about the hinge axis of the first hinged engagement portion and move closer to or away from the main shaft when it is linked.
[0013] The main clamping arm includes a second hinged engagement part, a second controlled part, and a first linkage part. The second hinged engagement part is hinged to the second hinged part. The first linkage part is connected to the second controlled part and is linked to the first controlled part. The first linkage part can follow the movement of the second controlled part and link with the first controlled part. The second controlled part is connected to the slider. When controlled by the slider, the second controlled part is used to rotate the main clamping arm relative to the second hinged part around the hinge axis of the second hinged engagement part until it abuts against the main shaft. It also links the first controlled part through the first linkage part so that the secondary clamping arm cooperates with the main clamping arm to clamp the main shaft. When the slider stops sliding, it stops abutting against the main shaft and links the first controlled part through the first linkage part so that the secondary clamping arm cooperates with the main clamping arm to release the main shaft.
[0014] Optionally, the main clamping arm and the auxiliary clamping arm are a cross structure stacked vertically, with the auxiliary clamping arm located above the main clamping arm. The connection position of the first controlled part and the first linkage part is located on the center line of the cross structure and is farther away from the main shaft than the intersection point of the cross structure.
[0015] 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.
[0016] Optionally, the secondary clamping arm further includes a first clamping arc segment and at least one first abutment portion, wherein the at least one first abutment portion is spaced apart on the first clamping arc segment along the circumferential direction of the first clamping arc segment;
[0017] The auxiliary clamping arm further includes a second clamping arc segment and at least one second abutment portion. The at least one second abutment portion is spaced apart on the second clamping arc segment along its circumferential direction. The first clamping arc segment and the second clamping arc segment are arranged opposite to each other. The main shaft is arranged between the first clamping arc segment and the second clamping arc segment. Each of the first clamping arc segment and the second clamping arc segment circumferentially surrounds the main shaft. The second clamping arc segment is used to abut against the main shaft through the second abutment portion when the main clamping arm and the auxiliary clamping arm clamp the main shaft. The first clamping arc segment is used to cooperate with the second clamping arc segment to abut against the main shaft through the first abutment portion when the main clamping arm and the auxiliary clamping arm clamp the main shaft.
[0018] Optionally, the slider includes:
[0019] A push button, mounted on the housing, for sliding to the locked or unlocked position under external force; and
[0020] A push button bracket is disposed inside the housing and connected to the push button. The push button bracket is also connected to the second controlled part. The push button bracket is used to follow the push button and control the second controlled part when sliding to the locking position, so that the main clamping arm and the auxiliary clamping arm clamp the main shaft. When sliding to the unlocking position, the control of the second controlled part is stopped, so that the main clamping arm and the auxiliary clamping arm release the main shaft.
[0021] Optionally, the push button bracket includes an abutting inclined surface aligned with the second controlled part. The abutting inclined surface can abut against and push the second controlled part when the push button bracket slides to the locking position, so as to control the main clamping arm and the auxiliary clamping arm to clamp the main shaft by controlling the second controlled part. When the push button bracket slides to the unlocking position, it abuts against or disengages from the second controlled part, so as to release the main clamping arm and the auxiliary clamping arm from the main shaft by stopping the control of the second controlled part.
[0022] Optionally, the housing is provided with a first slot and a second slot, the first slot and the second slot being respectively located at different positions on the sliding stroke of the push button, the push button bracket including a locking part, the locking part being able to engage with the first slot when the push button bracket slides to the locking position, and engage with the second slot when the push button bracket slides to the unlocking position.
[0023] In a second aspect, embodiments of this application also provide a laser level, comprising:
[0024] Box body;
[0025] A pendulum body, which is installed inside the box;
[0026] A laser emission assembly is mounted on the pendulum body and is used to project a laser line outward.
[0027] A driving assembly, installed within the housing, drivingly connected to the pendulum, the driving assembly driving the pendulum to adjust the projection direction of the laser emission assembly; and
[0028] The clamping assembly as described in any of the preceding claims is connected to the pendulum body and is capable of clamping the pendulum body.
[0029] Optionally, the laser level also includes a micro switch, a power supply, and a circuit board. The micro switch, the power supply, and the circuit board are all housed within the housing. The micro switch is electrically connected to the power supply and the circuit board, respectively, and the micro switch remains in a normally off state.
[0030] The slider includes a second linkage part, and the micro switch is disposed on the sliding stroke of the second linkage part. The second linkage part is used to connect with the micro switch and control the micro switch to close when the slider slides to the unlock position, so that the power supply supplies power to the circuit board, and to stop controlling the micro switch when the slider slides to the locking position, so that the micro switch returns to the normally open state.
[0031] In a third aspect, embodiments of this application also provide a calibration device, comprising:
[0032] Base;
[0033] The main frame is vertically mounted on the base;
[0034] A crossbeam, which is mounted on the main frame; and
[0035] The laser level as described in any of the above claims is detachably mounted on the beam.
[0036] In a fourth aspect, embodiments of this application also provide a calibration system, including:
[0037] The calibration equipment described above; and
[0038] A diagnostic instrument, which is communicatively connected to the calibration device.
[0039] The embodiments of this application achieve the following technical effects: The laser level of this application embodiment is equipped with a clamping assembly. The clamping assembly, through the mutual cooperation of a clamping mechanism and a slider, achieves locking protection for the pendulum. Under external force, the slider can slide relative to the housing. When it slides to the locked position, the slider drives the clamping mechanism to move and clamp the pendulum, fixing it in a specific position inside the housing and preventing collisions during transportation or vibration. When the slider slides to the unlocked position, the slider stops controlling the clamping mechanism, and the clamping mechanism releases the pendulum, allowing it to return to its free state and function normally. This structural design ensures that the laser level can reliably lock the pendulum when not in use, preventing damage from collisions between the pendulum and other components.

[0050] To facilitate understanding of this application, a more detailed description is provided below with reference to the accompanying drawings and specific embodiments. It should be noted that when an element is described as "connected" to another element, it can be directly on the other element, or one or more intermediate elements can exist between them. The terms "upper," "lower," "left," "right," "upper end," "lower end," "top," and "bottom," etc., used in this specification, indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0051] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application.
[0052] A laser level is used to project a laser line and can be applied in automotive calibration scenarios. It is mounted on the crossbeam of an automotive calibration device, providing a reference line in applications such as automotive calibration. Internally, a laser level contains a pendulum, a laser emission assembly, and a drive assembly. The pendulum houses the laser emission assembly, and the drive assembly drives and connects to the pendulum. Driven by the drive assembly, the pendulum can swing or rotate to adjust the projected laser line. However, in the laser level described in the relevant technical content, when not in use or during transportation, the internal pendulum is susceptible to vibration or external forces, potentially colliding with other components inside the housing and causing damage to the pendulum or other parts.
[0053] Please refer to Figures 1 and 2 together. In order to solve the above-mentioned technical problems, in a first aspect, embodiments of this application provide a clamping component applied to a laser level.
[0054] In some embodiments, the laser level 100 includes a housing 10, a pendulum 20, and a clamping assembly. The clamping assembly includes a clamping mechanism 30 and a slider 40. The pendulum 20 is installed inside the housing 10, and the clamping mechanism 30 is installed inside the housing 10 and can clamp the pendulum 20. The slider 40 is installed on the housing 10 and connected to the clamping mechanism 30 inside the housing 10. The slider 40 can slide relative to the housing 10. The sliding stroke of the slider 40 includes a locked position and an unlocked position. The slider 40 is used to control the clamping mechanism 30 to clamp the pendulum 20 when sliding to the locked position, and to stop controlling the clamping mechanism 30 when sliding to the unlocked position, so that the clamping mechanism 30 releases the pendulum 20.
[0055] The working principle of the laser level 100 provided in this embodiment is as follows: The laser level 100 is equipped with a clamping component, which locks and protects the pendulum 20 by means of a clamping mechanism 30 and a slider 40 that cooperate with each other. Under external force, the slider 40 can slide relative to the housing 10. When it slides to the locked position, the slider 40 drives the clamping mechanism 30 to move and clamp the pendulum 20, fixing the pendulum 20 in a specific position inside the housing 10, preventing the pendulum 20 from colliding during transportation or vibration. When the slider 40 slides to the unlocked position, the slider 40 stops controlling the clamping mechanism 30, and the clamping mechanism 30 releases the pendulum 20, allowing the pendulum 20 to return to its free state and function normally. This structural design allows the laser level 100 to reliably lock the pendulum 20 when not in use, preventing damage from collisions between the pendulum 20 and other components.
[0056] It is understood that the laser level 100 of this application embodiment, through the cooperation of the slider 40 and the clamping mechanism 30, effectively protects the pendulum 20 during non-use or transportation, reduces the risk of damage caused by collision between the pendulum 20 and other components, and is simple and convenient to operate, thereby improving the reliability and service life of the laser level 100.
[0057] In some embodiments, the clamping mechanism 30 includes two independent clamping arms, which are respectively hinged and installed inside the housing 10. The two independent clamping arms are arranged opposite to each other. The swing body 20 is disposed between the two independent clamping arms. Each independent clamping arm can rotate relative to the swing body 20 about the hinge axis. The slider 40 is connected to each independent clamping arm. The slider 40 is used to control the two independent clamping arms to clamp the swing body 20 when sliding to the locking position, and to stop controlling the two independent clamping arms when sliding to the unlocking position, so that the two independent clamping arms release the swing body 20.
[0058] Understandably, this embodiment of the application uses two independent clamping arms, which together 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.
[0059] Please refer to Figures 3 and 4 together. In some embodiments, the clamping mechanism 30 includes a secondary clamping arm 31 and a primary clamping arm 32. The secondary clamping arm 31 is hingedly mounted inside the housing 10 and can rotate relative to the swing body 20 about its own hinge axis. The primary clamping arm 32 is hingedly mounted inside the housing 10 and is connected to the secondary clamping arm 31. The primary clamping arm 32 is connected to and controlled by the slider 40. The primary clamping arm 32 and the secondary clamping arm 31 are arranged opposite to each other. The swing body 20 is arranged between the primary clamping arm 32 and the secondary clamping arm 31. The primary clamping arm 32 can rotate relative to the swing body 20 about its own hinge axis under the control of the slider 40, and can also clamp the swing body 20 by linking the secondary clamping arm 31, and release the swing body 20 by linking the secondary clamping arm 31 when the slider 40 stops.
[0060] Understandably, the design of the main clamping arm 32 and the auxiliary clamping arm 31 allows the pendulum 20 to be quickly and effectively fixed when subjected to vibration or external force, ensuring the stability of the pendulum 20. The auxiliary clamping arm 31 and the main clamping arm 32 are respectively hinged within the housing 10, with the main clamping arm 32 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 20. This application achieves rapid fixing and releasing of the pendulum 20 through the linkage of the main clamping arm 32 and the auxiliary clamping arm 31, improving operational convenience and reducing the risk of damage caused by vibration or external force.
[0061] Please refer to Figures 3 to 5 together. In some embodiments, the housing 10 includes a first hinge portion 11 and a second hinge portion 12, and the swing body 20 includes a main shaft 21. The auxiliary clamping arm 31 includes a first hinge engagement portion 311 and a first controlled portion 312. The first hinge engagement portion 311 and the first hinge portion 11 are hinged together. The first controlled portion 312 is used to cause the auxiliary clamping arm 31 to rotate relative to the first hinge portion 11 about the hinge axis of the first hinge engagement portion 311 and move closer to or away from the main shaft 21 when it is linked.
[0062] The main clamping arm 32 includes a second hinged engagement part 321, a second controlled part 322, and a first linkage part 323. The second hinged engagement part 321 is hinged to the second hinged part 12. The first linkage part 323 is connected to the second controlled part 322 and is also connected to the first controlled part 312. The first linkage part 323 can follow the movement of the second controlled part 322 and link with the first controlled part 312. The second controlled part 322 is connected to the slider 40 and is used to move the slider. When block 40 is controlled, the main clamping arm 32 rotates relative to the second hinge part 12 around the hinge axis of the second hinge engagement part 321 until it abuts against the main shaft 21. The first control 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. When the slider 40 is controlled to slide and stop, it stops abutting against the main shaft 21. The auxiliary clamping arm 31 cooperates with the main clamping arm 32 to release the main shaft 21 through the first linkage part 323 and the first control part 312.
[0063] The main shaft 21 referred to in this application embodiment 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, so that it swings or rotates.
[0064] Understandably, the second controlled part 322 of the main clamping arm 32, under the control of the slider 40, drives the entire main clamping arm 32 to rotate around the second hinged engagement part 321. Simultaneously, the first controlled part 312 of the auxiliary clamping arm 31 is driven to move through the first linkage part 323, causing the auxiliary clamping arm 31 to rotate around the first hinged engagement part 311. The two clamping arms move in coordination until they clamp the main shaft 21. The embodiment of this application ensures the accuracy and synchronization of the clamping action through the above-mentioned settings, and reliably achieves the clamping of the main shaft 21.
[0065] In some embodiments, the main clamping arm 32 and the secondary clamping arm 31 are stacked vertically in a cross structure, with the secondary clamping arm 31 located above the main clamping arm 32. The connection point between the first controlled part 312 and the first linkage part 323 is located on the center line of the cross structure and is farther from the main shaft 21 than the intersection point. The second controlled part is located on the center line of the cross structure and is farther 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.
[0066] For example, 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 near 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, and the first linkage part 323 is provided with a socket. The plug is inserted into the socket, and a large gap is provided between the socket and the plug, so that the plug has a certain rotation stroke in the socket, which can prevent the main clamping arm 32 and the auxiliary clamping arm 31 from locking each other and being unable to rotate. The first socket can rotate relative to the second hinge part 12 around the hinge axis of the second hinge mating part 321 with the second controlled part 322, and push the plug to rotate relative to the first hinge part 11 around the hinge axis of the first hinge mating part 311 through the inner wall, so that the main clamping arm 32 and the auxiliary clamping arm 31 come closer to each other and clamp the main shaft 21.
[0067] As another example, one of the first hinge portion 11 and the first hinge mating portion 311 is a hinge hole, and the other is a hinge shaft. The two are hinged through the mutual connection of the hole and the shaft. Correspondingly, one of the second hinge portion 12 and the second hinge mating portion 321 is a hinge hole, and the other is a hinge shaft. The two are hinged through the mutual connection of the hole and the shaft. In some embodiments, the first hinge mating portion 311 is located at one end of the secondary clamping arm 31, and the second hinge mating portion 321 is located at one end of the main clamping arm 32, thereby reducing the volume of both the secondary clamping arm 31 and the main clamping arm 32, which helps to reduce the space occupied by the clamping mechanism 30 in the housing 10.
[0068] In some embodiments, the secondary clamping arm 31 further includes a first clamping arc segment 313 and at least one first abutment portion 314, wherein at least one first abutment portion 314 is spaced apart on the first clamping arc segment 313 along the circumferential direction of the first clamping arc segment 313.
[0069] The auxiliary clamping arm 31 also includes a second clamping arc segment 324 and at least one second abutment portion 325. The at least one second abutment portion 325 is spaced apart on the second clamping arc segment 324 along the circumferential direction. The first clamping arc segment 313 and the second clamping arc segment 324 are arranged opposite 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 is circumferentially surrounding the main shaft 21. The second clamping arc segment 324 is used to abut against the main shaft 21 through the second abutment 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 to abut against the main shaft 21 through the first abutment portion 314 when the main clamping arm 32 and the auxiliary clamping arm 31 clamp the main shaft 21.
[0070] Understandably, the embodiments of this application, through the circumferential arrangement of the first clamping arc segment 313 and the second clamping arc segment 324, can clamp the main shaft 21 from multiple directions, thus ensuring the stability of the pendulum 20.
[0071] To be more easily understood, this embodiment of the application improves the clamping effect by providing a clamping arc segment and abutment portions on the clamping arm. Multiple abutment portions are provided circumferentially along the main shaft 21 in the first clamping arc segment 313 and the second clamping arc segment 324. When the clamping arm is closed, these abutment portions can simultaneously abut against the main shaft 21 at multiple points, increasing the contact area and dispersing the force. This ensures a stable clamping effect while preventing excessive local force from damaging the main shaft 21. Furthermore, the multiple abutment portions can abut against the circumferential surface of the main shaft 21 from different directions, effectively clamping the main shaft 21 and preventing the main shaft 21 from experiencing slight swaying under vibration due to gaps between the main shaft 21 and either the first clamping arc segment 313 or the second clamping arc segment 324.
[0072] Specifically, the first clamping arc segment 313 and the second clamping arc segment 324 are arc-shaped structures, respectively disposed on the corresponding clamping arms. They are arranged opposite each other and together surround the main axis 21 of the swing body 20. The first abutment portion 314 and the second abutment portion 325 are protrusions respectively disposed on the corresponding clamping arc segments and are distributed at intervals along the inner circumferential surface of the corresponding clamping arc segments. They are used for multi-point contact with the main axis 21 to provide a more stable fixing effect and avoid local damage to the main axis 21 by dispersing the force points.
[0073] 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 housing 10 and is used to slide to a locked position or an unlocked position under the action of an external force.
[0074] The push button bracket 42 is disposed inside the housing 10. The push button bracket 42 is connected to the push button 41 and 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. When sliding to the unlocking position, the control of the second controlled part 322 is stopped so that the main clamping arm 32 and the auxiliary clamping arm 31 release the main shaft 21.
[0075] Understandably, this embodiment of the application achieves convenient control of the swing body 20 through the cooperation of the push button 41 and the push button bracket 42. The push button 41 is mounted on the housing 10 for easy operation, and can be slid to the locked or unlocked position by external pushing force. The push button bracket 42 is connected to the push button 41 and extends into the housing 10, connecting 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 it with the auxiliary clamping arm 31, ultimately achieving the clamping or releasing of the main shaft 21. This embodiment of the application achieves effective connection of the internal and external structures, is convenient to operate and has reliable force transmission, improving the overall performance of the mechanism.
[0076] In some embodiments, the second controlled portion 322 is a portion of the main clamping arm 32 that is directly controlled by the slider 40 and is configured to fit into the abutting slope 421 of the push button bracket 42. Exemplarily, the second controlled portion 322 is a protruding structure and is configured with an abutting arc surface.
[0077] Please refer to Figure 5. In some embodiments, the push button bracket 42 includes an abutting inclined surface 421, which is aligned with the second controlled part 322. When the push button bracket 42 slides to the locked position, the abutting inclined surface 421 abuts against and pushes the second controlled part 322, so as to control the main clamping arm 32 and the linked secondary 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 unlocked position, it abuts against or disengages from the second controlled part 322, so as to release the main clamping arm 32 and the secondary clamping arm 31 from the main shaft 21 by stopping the control of the second controlled part 322.
[0078] Understandably, this embodiment of the application, by providing an abutting inclined surface 421 on the push button bracket 42 to cooperate with the second controlled part 322, can push the second controlled part 322 to rotate through the abutting inclined surface 421. When the push button bracket 42 slides to the locked position, the abutting inclined surface 421 will gradually push the second controlled part 322, causing the main clamping arm 32 to rotate smoothly and drive the auxiliary clamping arm 31 until it fully clamps the main shaft 21; when the push button bracket 42 slides to the unlocked position, the abutting inclined surface 421 gradually disengages from the second controlled part 322, causing the clamping mechanism 30 to be released smoothly. This embodiment of the application, by using the abutting inclined surface 421 to push the second controlled part 322, not only ensures the smoothness of the locking and unlocking process, but also reduces the impact wear between mechanisms and extends the service life of components.
[0079] Please refer to Figures 6 and 7 together. In some embodiments, the box body 10 is provided with a first slot 13 and a second slot 14. The first slot 13 and the second slot 14 are respectively disposed at different positions on the sliding stroke of the push button bracket 42. The push button bracket 42 includes a locking part 422, which can engage with the first slot 13 when the push button bracket 42 slides to the locked position, and engage with the second slot 14 when the push button bracket 42 slides to the unlocked position.
[0080] Understandably, this embodiment of the application forms a reliable position locking by providing a first slot 13 and a second slot 14 on the housing 10 and a corresponding engaging portion 422 on the push button bracket 42. When the push button bracket 42 slides to the locked or unlocked position, the engaging portion 422 engages with the corresponding slot, producing a clear sense of positioning and preventing the push button 41 from moving accidentally. This dual-position engaging 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 shifting accidentally during use, improving the reliability and safety of the entire clamping mechanism 30.
[0081] Please refer to Figures 1 and 2. In a second aspect, embodiments of this application also provide a laser level 100, including a housing 10, a pendulum 20, a laser emission assembly, a drive assembly, and the aforementioned clamping assembly. The pendulum 10 is mounted inside the housing. The laser emission assembly is mounted on the pendulum 10 and is used to project a laser line outward. The drive assembly is mounted inside the housing 10 and drives the pendulum 20 to adjust the projection direction of the laser emission assembly. The clamping assembly is connected to the pendulum and is capable of clamping the pendulum.
[0082] Understandably, the laser level 100 of this application embodiment is equipped with a clamping assembly. This clamping assembly, through the mutually cooperating clamping mechanism 30 and slider 40, achieves locking protection for the pendulum 20. The slider 20 can slide relative to the housing 10 under external force. When it slides to the locked position, the slider 40 drives the clamping mechanism 30 to move and clamp the pendulum 20, fixing the pendulum 20 in a specific position inside the housing 10, preventing collisions during transportation or vibration. When the slider 40 slides to the unlocked position, the slider 40 stops controlling the clamping mechanism 30, and the clamping mechanism 30 releases the pendulum 20, allowing it to return to its free state and function normally. This structural design ensures that the laser level 100 can reliably lock the pendulum 20 when not in use, preventing damage from collisions between the pendulum 20 and other components.
[0083] The laser emission assembly includes at least one laser emitter mounted on the pendulum 20, and the drive assembly can drive the pendulum 20 to swing or rotate, thereby changing the emission direction of the laser emitter.
[0084] Please refer to Figures 6 and 8. In some embodiments, the laser level 100 also 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 disposed inside the housing 10. The micro switch 50 is electrically connected to the power supply and the circuit board, respectively, and the micro switch 50 is kept in a normally off state.
[0085] The slider 40 includes a second linkage part 423, and a micro switch 50 is disposed on the sliding stroke of the second linkage part 423. The second linkage part 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 unlock position so that the power supply can supply power to the circuit board, and to stop controlling the micro switch 50 when the slider 40 slides to the locking position so that the micro switch 50 returns to the normally open state.
[0086] Understandably, this embodiment integrates the micro switch 50, power supply, and circuit board within the housing 10, and links them with the second linkage part 423 of the slider 40, thus achieving linkage between the locking mechanism and power control. The micro switch 50 is normally open; it is only triggered by the second linkage part 423 to close when the slider 40 slides to the unlocked position, thereby supplying power to the circuit board. When the slider 40 returns to the locked position, the micro switch 50 automatically opens. This embodiment organically combines mechanical locking with power control, preventing accidental power supply in the locked state and automatically turning on the power when unlocked, improving the safety and ease of use of the device.
[0087] 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 disengaged, the micro switch 50 is in an open state; when the switch spring 51 and the switch contact 52 are in contact, the micro switch 50 is in a closed state. The switch spring 51 is disposed on the sliding stroke of the second linkage part 423. Exemplarily, the second linkage part 423 is disposed on the push button bracket 42. Specifically, the second linkage part 423 is a push block, which is used to abut the switch spring 51 when the slider 40 slides to the unlock position, so that the switch spring 51 abuts the switch contact 52, and to stop abutting the switch spring 51 when the slider 40 slides to the lock position, so that the switch spring 51 returns to its original shape and disengages from the switch contact 52.
[0088] Understandably, this embodiment employs a combination design of switch spring 51 and switch contact 52, along with a push block on slider 40, to form a reliable circuit switching mechanism. When slider 40 slides to the unlocked position, the push block abuts against switch spring 51, making it contact switch contact 52 to form a closed loop; when slider 40 returns to the locked position, switch spring 51 recovers its deformation under its own elasticity and disengages from switch contact 52, ensuring the circuit is disconnected. This embodiment uses an electrical connection triggering method of switch spring 51 and 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 effectively reduces the instantaneous impact of the electrical switch and extends the service life of the micro switch 50.
[0089] Referring to Figures 1 and 9, in a third aspect, the calibration device 1000 provided in this application embodiment includes a base 200, a main frame 300, a crossbeam 400, and the laser level 100 described in the above embodiment. The main frame 300 is vertically fixed to the base 200, and the crossbeam 400 is horizontally installed on top of the main frame 300, forming a stable frame structure. The laser level 100 is detachably installed on the crossbeam 400 via a quick-release interface or a magnetic adsorption assembly, facilitating adjustment of its installation position or replacement with different models of laser levels according to actual calibration requirements.
[0090] During vehicle calibration, the laser level 100 projects a high-precision laser line through its laser emission component, serving as a reference for vehicle calibration. When the calibration device 1000 is in operation, the user slides the slider 40 to the unlocked position. At this time, the clamping mechanism 30 releases the pendulum 20, and the drive component drives the pendulum 20 to swing freely to dynamically adjust the projection angle of the laser line. Simultaneously, the second linkage part 423 of the slider 40 triggers the micro switch 50 to close, energizing the circuit board and activating the laser emission and automatic calibration functions. When calibration is complete or the equipment needs to be transported, the user pushes the slider 40 to the locked position. The clamping mechanism 30 simultaneously clamps the main shaft 21 of the pendulum 20 to prevent vibration from causing the pendulum 20 to collide with the inside of the housing 10; at the same time, the micro switch 50 is deactivated, cutting off the power supply to save energy and ensure safety.
[0091] In a fourth aspect, this application also provides a calibration system, which includes the calibration device 1000 and a diagnostic instrument as described in the above embodiments, and the diagnostic instrument is communicatively connected to the calibration device 1000.
[0092] The diagnostic tool can be a flat-panel diagnostic tool for easy portability and transport. Optionally, a vision camera is mounted on the crossbeam of the calibration device 1000. The vision camera is communicatively connected to the diagnostic tool, which can be used to receive vehicle image data captured by the vision camera.
[0093] Optionally, the calibration system may also include calibration elements such as targets and reflectors, which can be mounted on the crossbeam.
[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and not to limit them; under the concept of this application, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of different aspects of this application as described above, which are not provided in detail for the sake of brevity; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
