[0003] Taking a four-wheel alignment machine as an example, it is used to detect whether the wheel positions have shifted, ensuring the vehicle's driving performance is normal. During testing, the positioning and orientation of the testing instruments on the four-wheel alignment machine are typically adjusted in the front-to-back, left-to-right, and up-and-down directions according to the actual situation to obtain more accurate wheel position information. Similarly, other types of automotive calibration equipment also require positioning and orientation adjustment.

[0029] The purpose of automotive calibration equipment is to ensure that various electronic control systems in a vehicle operate accurately and reliably. Depending on the target area being tested and calibrated, automotive calibration equipment can be further categorized into several types, such as four-wheel alignment equipment and ADAS calibration equipment.
[0030] Taking automotive four-wheel alignment equipment as an example, it is used to obtain key parameters of the vehicle's suspension system (such as caster angle, kingpin inclination angle, camber angle, and toe-in) through testing instruments to determine whether the wheel positions have shifted, thus ensuring the vehicle's normal driving performance. Currently, as car owners place increasing emphasis on vehicle maintenance, the demand for four-wheel alignment inspections is also constantly rising. Related testing agencies are considering providing on-site four-wheel alignment services to improve user experience, which necessitates transporting the four-wheel alignment equipment to the user's location. Therefore, the current market places higher demands on the portability of automotive four-wheel alignment equipment.
[0031] When using automotive four-wheel alignment equipment for testing, it is usually necessary to adjust the equipment's posture in the front-to-back, left-to-right, and up-to-down directions according to the actual situation to obtain more accurate wheel position information. To meet the needs of posture adjustment, some automotive four-wheel alignment equipment is equipped with a posture adjustment mechanism. However, due to the large size of the configured posture adjustment mechanism, it adversely affects the portability of the equipment. To compromise on portability, some portable automotive four-wheel alignment equipment has directly eliminated the posture adjustment mechanism, requiring users to adjust it by moving the main frame or adjusting the base feet, which in turn leads to inconvenient adjustment operations. Similarly, other types of automotive calibration equipment, such as ADAS calibration equipment, also have the dual requirements of portability and ease of posture adjustment.
[0032] The inventors of this application have discovered that in some existing automotive calibration equipment, the posture adjustment mechanism uses different modules to achieve adjustments in different directions. These modules are separate and each requires its own space, resulting in low structural compactness. Therefore, the inventors of this application have considered integrating some of these modules, connecting multiple modules through a common connection structure to improve structural compactness.
[0033] According to one aspect of the embodiments of this application, a pose adjustment mechanism is provided, please refer to [the specific details]. Figures 1 to 4 ,in, Figure 1 and Figure 2 These are stereoscopic views of the pose adjustment mechanism 100 from different perspectives. Figure 2 The base 11 and part of the external structure of the mounting component 13 are hidden in the middle. Figure 3 The structure showing the connection between the first adjustment component 14 and the adapter 12 is illustrated. Figure 4 The structure of the second adjustment component 15 connected to the adapter 12 is shown. The posture adjustment mechanism 100 includes a base 11, an adapter 12, a mounting member 13, a first adjustment component 14, and a second adjustment component 15. The adapter 12 is movably connected to the base 11. The mounting member 13 is connected to the adapter 12 and is used to mount and fix the component to be adjusted. The first adjustment component 14 and the second adjustment component 15 each have a first output end and a second output end capable of outputting power. The first output end of the first adjustment component 14 is fixedly connected to at least one end of the adapter 12 in the vertical direction, and is used to drive the mounting member 13 to rotate around the vertical axis via the adapter 12. The second output end of the second adjustment component 15 is fixedly connected to at least one end of the adapter 12 in the first horizontal direction, and is used to drive the mounting member 13 to rotate around the first horizontal axis via the adapter 12.
[0034] Specifically, the base 11 is the basic connecting component of the posture adjustment mechanism 100, and it can usually be fixed in a stable installation position, such as the base of a car four-wheel alignment device, thereby fixing the usage position of the posture adjustment mechanism 100. The adapter 12 is movably connected to the base 11, and the mounting member 13 is connected to the adapter 12. Therefore, the mounting member 13 can move relative to the base 11. When the first adjustment component 14 and the second adjustment component 15 output power to the adapter 12, the adapter 12 can transmit power to the mounting member 13, thereby driving the mounting member 13 and the component to be adjusted fixed on the mounting member 13 to move relative to the base 11 to perform the required posture adjustment. Taking the first adjustment component 14 as an example, the first adjustment component 14 can output power to rotate around the vertical axis at one end of the adapter 12 in the vertical direction. The adapter 12 transmits this power to the mounting member 13, which can drive the mounting member 13 to rotate relative to the base 11, thereby realizing the posture adjustment of the component to be adjusted.
[0035] The component to be adjusted that is fixed on the mounting part 13 refers to a component whose position needs to be flexibly adjusted during use. For example, the component to be adjusted can be a distance measuring instrument or a camera component in a four-wheel alignment device. It is understood that the embodiments of this application do not have specific limitations on the application scenarios of the position adjustment mechanism 100. This mechanism can also be applied to other similar scenarios besides four-wheel alignment devices. Therefore, there are no limitations on the specific form of the component to be adjusted installed on the mounting part 13.
[0036] It is understandable that the first adjustment component 14 and the second adjustment component 15 typically also have input terminals for external force input. These input terminals may be equipped with handles, knobs, or other structures to facilitate the application of external force by the user. Figure 2 The input ends of the first adjustment component 14 and the second adjustment component 15 shown are respectively provided with knobs 161. In addition, the input ends of the first adjustment component 14 and the second adjustment component 15 can also be connected to drive components such as motors to achieve automatic adjustment. The specific design can be flexibly made according to the required adjustment method.
[0037] Taking the first adjustment component 14 as an example, optionally, the first output end can be connected to one end of the adapter 12 along the vertical direction, or it can be connected to the opposite ends of the adapter 12 along the vertical direction. Both connection methods can output power to the adapter 12 to rotate around the vertical axis. The specific connection method can be determined according to the actual structure of the first output end. For example, as Figure 3 and Figure 4As shown, when the first output terminal is connected to the adapter 12 via the first connecting shaft 162, and the first connecting shaft 162 extends from opposite ends of the adapter in the vertical direction, the first output terminal can be connected only to the upper end of the first connecting shaft 162, that is, connected to one end of the adapter 12 via the first connecting shaft 162. In the above scheme, when the first output terminal includes two sub-output terminals spaced apart in the vertical direction, each sub-output terminal can be connected to the upper and lower ends of the first connecting shaft 162 respectively, which is equivalent to the first output terminal being connected to opposite ends of the adapter 12 in the vertical direction. Similarly, the second output terminal of the second adjustment component 15 can also be selected to be connected to one end of the adapter 12 in the first horizontal direction, or connected to opposite ends of the adapter 12 in the first horizontal direction, depending on the actual structure.
[0038] In order to reduce the space occupied by the adapter 12 while meeting connectivity requirements, one implementation scheme is as follows: Figure 3 and Figure 4 As shown, the adapter 12 can be configured in a cross shape, forming a first adapter portion 121 extending vertically and a second adapter portion 122 extending horizontally. The output end of the first adjustment component 14 is fixedly connected to the first adapter portion 121, and the output end of the second adjustment component 15 is fixedly connected to the second adapter portion 122. Compared to configuring the adapter 12 in a conventional shape such as a cube, this configuration significantly saves space and reduces the weight of the adapter 12. Alternatively, the adapter 12 can also be configured in other shapes such as L-shape or T-shape, as long as it meets the connection requirements of the first adjustment component 14 and the second adjustment component 15.
[0039] The pose adjustment mechanism 100 provided in this application embodiment uses a connector 12 to carry the power output from the first adjustment component 14 and the second adjustment component 15. Depending on the direction of the power output from the different adjustment components, it can drive the mounting component 13 to rotate around different axes, achieving multi-dimensional pose adjustment. Furthermore, both the first adjustment component 14 and the second adjustment component 15 are connected to the same connector 12, achieving an integrated layout of the two adjustment components. This saves space occupied by repeatedly setting multiple connection structures, improves structural compactness, and reduces the overall size of the pose adjustment mechanism 100, thereby better meeting the portability requirements of applications such as automotive calibration equipment.
[0040] In some embodiments, please refer to Figure 3The adapter 12 is rotatably connected to the base 11 about a vertical axis. The first adjustment assembly 14 includes a first lead screw 141, a first nut 142, and a first connecting rod 143. The first lead screw 141 is rotatably connected to the base 11 about a first horizontal axis. The first nut 142 is threadedly connected to the first lead screw 141 to slide along a first horizontal direction under the drive of the first lead screw 141. A first connecting post 1421 extending vertically is provided on the first nut 142. The first connecting rod 143 is arranged parallel to a plane perpendicular to the vertical direction. A first connecting hole 1431 is opened at one end of the first connecting rod 143 along the vertical direction. The first connecting post 1421 is inserted into the first connecting hole 1431. The first connecting post 1421 is fixed relative to the first connecting hole 1431 along the first horizontal direction and can slide relative to the first connecting hole 1431 along a second horizontal direction perpendicular to the first horizontal direction. The other end of the first connecting rod 143 is fixedly connected to the adapter 12, and the connection position is on the vertical axis of rotation of the adapter 12 relative to the base 11. The first connecting rod 143 is used to drive the adapter 12 to rotate around the vertical axis when the first connecting column 1421 slides along the first horizontal direction, so as to realize the adjustment of the left and right orientation of the component to be adjusted.
[0041] Specifically, the rotatable connection between the adapter 12 and the base 11 can be achieved by using a shaft and bearing, for example, in one embodiment, such as Figure 3 As shown, the adapter 12 is rotatably connected to the base 11 via a first connecting shaft 162 extending vertically. Simultaneously, the first connecting rod 143 is fixedly connected to the adapter 12 via the first connecting shaft 162, ensuring that the connection point between the first connecting rod 143 and the adapter 12 is on the vertical axis of rotation of the adapter 12 relative to the base 11. This arrangement allows for simultaneous connection of the adapter 12 to the base 11 and the first connecting rod 143 to the adapter 12 via the first connecting shaft 162, eliminating the need for separate shaft structures for each connection and simplifying the structure. Of course, it is understood that the adapter 12 could also be directly rotatably connected to the base 11.
[0042] When the first lead screw 141 rotates around the first horizontal axis under the action of an external force, the first nut 142 drives the first connecting post 1421 to slide along the first horizontal direction. The first connecting post 1421 is inserted into the first connecting hole 1431 at the end of the first connecting rod 143. Furthermore, the first connecting hole 1431 allows the first connecting post 1421 to slide in the second horizontal direction. Therefore, when the first connecting post 1421 moves along the first horizontal direction, it can drive the first connecting rod 143 to swing around its connection point with the adapter 12. Since the connection point between the first connecting rod 143 and the adapter 12 is on the vertical axis of rotation of the adapter 12 relative to the base 11, the swing of the first connecting rod 143 can be converted into the rotational motion of the adapter 12 around the vertical axis. Finally, the adapter 12 drives the mounting part 13 to rotate, thereby realizing the adjustment of the left and right orientation of the component to be adjusted.
[0043] To facilitate the application of a rotational force about a first horizontal axis to the first lead screw 141, in one embodiment, such as Figure 3 As shown, a knob 161 can be fixedly connected to one end of the first lead screw 141, and the user can rotate the first lead screw 141 by rotating the knob 161.
[0044] In the above embodiments, the first adjustment component 14 employs a transmission mechanism formed by a first lead screw 141, a first nut 142, and a first connecting rod 143, thereby realizing the rotational adjustment of the mounting component 13 around a vertical axis. The rotational speed of the first lead screw 141 is significantly reduced after multiple stages of transmission through the first nut 142 and the first connecting rod 143. Even if the rotation amplitude of the first lead screw 141 is large, the final rotation amplitude of the mounting component 13 remains small, thus significantly improving the adjustment accuracy and meeting the needs for fine-tuning in some application scenarios.
[0045] In some embodiments, please refer to Figure 4The mounting component 13 and the adapter 12 are rotatably connected around a first horizontal axis. The second adjusting assembly 15 includes a second lead screw 151, a second nut 152, and a second connecting rod 153. The second lead screw 151 is rotatably connected to the mounting component 13 around a vertical axis. The second nut 152 is threadedly connected to the second lead screw 151, allowing it to slide vertically under the drive of the second lead screw 151. A second connecting post 1521 extending along the first horizontal direction is provided on the second nut 152. The second connecting rod 153 is parallel to a plane perpendicular to the first horizontal direction. One end of the second connecting rod 153 has a first connecting hole 1431 along the first horizontal direction. The second connecting post 1521 is inserted into the second connecting hole 1531. The second connecting post 1521 is fixed relative to the second connecting hole 1531 in the vertical direction and can slide relative to the second connecting hole 1531 in the second horizontal direction. The other end of the second connecting rod 153 is fixedly connected to the adapter 12, and the connection position is on the first horizontal axis of rotation of the mounting member 13 relative to the adapter 12. The second connecting rod 153 is used to drive the mounting member 13 to rotate relative to the adapter 12 around the first horizontal axis when the second connecting column 1521 slides in the vertical direction, so as to realize the pitch adjustment of the component to be adjusted.
[0046] Specifically, the rotatable connection between the mounting component 13 and the adapter 12 can be achieved by using a shaft and bearing assembly. For example, in one embodiment, such as... Figure 4 As shown, the adapter 12 is rotatably connected to the mounting component 13 via a second connecting shaft 163 extending along a first horizontal direction. Simultaneously, the second connecting rod 153 is fixedly connected to the adapter 12 via the second connecting shaft 163, ensuring that the connection point between the second connecting rod 153 and the adapter 12 is on the first horizontal axis of rotation of the mounting component 13 relative to the adapter 12. This configuration allows for simultaneous connection of the adapter 12 to the mounting component 13 and the second connecting rod 153 to the adapter 12 via the second connecting shaft 163, eliminating the need for separate shaft structures for each connection and simplifying the structure. Similarly, the rotatable connection between the second lead screw 151 and the mounting component 13 can also be achieved using a shaft and bearing assembly, which will not be elaborated upon here.
[0047] It is understood that the specific structure and movement of the second adjustment component 15 are similar to those of the first adjustment component 14 in the above embodiment, and will not be described in detail here. Unlike the first adjusting assembly 14 described above, the second lead screw 151 in the second adjusting assembly 15 is rotatably connected to the mounting member 13, rather than to the base 11. Furthermore, since the adapter 12 is rotatably connected to the base 11 about the vertical axis, the rotation of the adapter 12 about the first horizontal axis is restricted by the base 11. Therefore, when the second lead screw 151 rotates about the vertical axis, the second connecting rod 153 does not directly drive the adapter 12 to rotate about the first horizontal axis. Instead, the adapter 12 applies a reaction force to the second connecting rod 153, which transmits this reaction force to the second nut 152 and the second lead screw 151. Since the second lead screw 151 is fixed to the mounting member 13, and the mounting member 13 is rotatably connected to the adapter 12 about the first horizontal axis, this reaction force causes the second lead screw 151 and the mounting member 13 as a whole to rotate about the first horizontal axis relative to the adapter 12. Thus, through the above-mentioned motion process, the rotation of the second lead screw 151 around the vertical axis is ultimately converted into the rotation of the mounting component 13 around the first horizontal axis, and the mounting component 13 then drives the component to be adjusted to perform pitch adjustment.
[0048] In the above embodiments, the second adjustment component 15 employs a transmission mechanism formed by the combination of a second lead screw 151, a second nut 152, and a second connecting rod 153, thereby realizing the rotational adjustment of the mounting component 13 around the first horizontal axis. Similar to the first adjustment component 14, the design of the second adjustment component 15 significantly improves the adjustment accuracy. Furthermore, by rotatably connecting the mounting component 13 and the adapter 12 around the first horizontal axis, and rotatably connecting the second lead screw 151 around the vertical axis to the mounting component 13, this configuration cleverly utilizes the reaction force applied by the adapter 12 to achieve the rotation of the mounting component 13 around the first horizontal axis, even when the rotation of the adapter 12 around the first horizontal axis is restricted by the base 11. This avoids the problem of the second adjustment component 15 failing due to the restricted movement of the adapter 12, ensuring that multi-dimensional adjustment needs can still be met despite the integrated design.
[0049] In some embodiments, please refer to Figure 5 and Figure 6Along the second horizontal direction, the connection point between the first lead screw 141 and the first nut 142 is located between the two ends of the first connecting rod 143, and the connection point between the second lead screw 151 and the second nut 152 is located between the two ends of the second connecting rod 153. The axis of rotation of the adapter 12 relative to the base 11 is located on the side of the mounting part 13 relative to the axis of rotation of the adapter 12 along the second horizontal direction away from the base 11. For example, when the adapter 12 is rotatably connected to the base 11 via the first connecting shaft 162, and the adapter 12 is rotatably connected to the mounting part 13 via the second connecting shaft 163, the first connecting shaft 162 is located on the side of the second connecting shaft 163 along the second horizontal direction away from the base 11.
[0050] In the above embodiments, by arranging the first lead screw 141 and the first nut 142 between the two ends of the first connecting rod 143, the first lead screw 141 and the first nut 142 can utilize the space occupied by the first connecting rod 143 in the second horizontal direction. Similarly, the second lead screw 151 and the second nut 152 can utilize the space occupied by the second connecting rod 153 in the second horizontal direction, thereby saving the overall size of the first adjusting assembly 14 and the second adjusting assembly 15 in the second horizontal direction and improving the compactness of the structure. Furthermore, by setting the axis of rotation of the adapter 12 relative to the base 11 on the side opposite to the axis of rotation of the mounting member 13 relative to the adapter 12, the position of the first connecting rod 143 connecting the adapter 12 is far away from the first connecting hole 1431 in the second horizontal direction. This allows the length of the first connecting rod 143 to be increased within a limited space. With this arrangement, when the first connecting column 1421 slides the same distance, the angle of swing of the first connecting rod 143 is smaller, which in turn makes the angle of rotation of the mounting member 13 around the vertical axis smaller, resulting in higher precision in rotation adjustment. Correspondingly, the position of the second connecting rod 153 connecting the adapter 12 is also away from the second connecting hole 1531 in the second horizontal direction. Therefore, similarly to the above, this arrangement can also make the mounting part 13 rotate around the first horizontal axis with higher precision.
[0051] In some embodiments, please refer to Figure 3 and Figure 4 The mounting member 13 extends toward the base 11 on both sides along the first horizontal direction to form sidewalls 131, and a receiving cavity 132 is formed between the two sidewalls 131. At least a portion of the adapter 12 is disposed in the receiving cavity 132, and at least one end of the adapter 12 along the first horizontal direction is rotatably connected to the sidewall 131.
[0052] The sidewalls 131 can be plate-like structures formed by the mounting member 13 extending towards the base 11 on both sides in the first horizontal direction. The accommodating cavity 132 formed between the two sidewalls 131 can accommodate the adapter 12. Depending on the design, the adapter 12 can be completely housed within the accommodating cavity 132. For example, when the adapter 12 is rotatably connected to the sidewalls 131 via the second connecting shaft 163, such as... Figure 4 As shown, the second connecting shaft 163 can be connected simply by passing it through the side wall 131. Of course, the adapter 12 can also extend partially out of the receiving cavity 132. For example, in a scheme where the adapter 12 is directly connected to the mounting member 13, the adapter 12 can be connected by passing it through the side wall 131.
[0053] In the above embodiment, the accommodating cavity 132 formed by the side wall 131 accommodates at least a portion of the structure of the adapter 12, and the side wall 131 can be connected to the adapter 12. This design places the adapter 12 between the base 11 and the mounting member 13, which not only realizes the connection between the adapter 12 and the mounting member 13, but also facilitates the connection between the adapter 12 and the base 11, resulting in a compact structural layout.
[0054] In some embodiments, please refer to Figure 3 and Figure 4 Both ends of the adapter 12 in the vertical direction are rotatably connected to the base 11, and both ends of the adapter 12 in the first horizontal direction are rotatably connected to the mounting part 13. For example, as Figure 3 As shown, when the adapter 12 is rotatably connected to the base 11 via the first connecting shaft 162, the first connecting shaft 162 can pass through the adapter 12, so that both ends of the first connecting shaft 162 in the vertical direction are rotatably connected to the base 11 via bearings. Similarly, when the adapter 12 is rotatably connected to the mounting member 13 via the second connecting shaft 163, the second connecting shaft 163 can pass through the adapter 12, so that both ends of the second connecting shaft 163 in the first horizontal direction are rotatably connected to the mounting member 13 via bearings.
[0055] Optionally, such as Figure 3 and Figure 4 As shown, the adapter 12 can be configured as a cross-shaped structure, wherein both ends of the first adapter 121 are rotatably connected to the mounting member 13, and both ends of the second adapter 122 are rotatably connected to the mounting member 13. With this configuration, end supports are formed between the adapter 12 and the base 11, and between the adapter 12 and the mounting member 13, resulting in a stable support structure. Furthermore, the center of gravity of the adapter 12 is located at the center of the cross shape, ensuring stability during rotation and thus improving the smoothness of rotation.
[0056] The above embodiment provides stable support for the adapter 12 by rotatably connecting both ends of the adapter 12 in the vertical direction to the base 11 and rotatably connecting both ends of the adapter 12 in the first horizontal direction to the mounting member 13, thus ensuring balance and stability during rotation.
[0057] In some embodiments, please refer to Figure 2 and Figure 3 The base 11 has first connecting seats 111 at both ends of the first nut 142 along the first horizontal direction, and the first lead screw 141 is rotatably connected to the two first connecting seats 111 respectively. The first nut 142 has a first sliding groove 1422 extending along the first horizontal direction. The posture adjustment mechanism 100 also includes a first guide rod 171, which passes through the first sliding groove 1422 along the first horizontal direction, and both ends of the first guide rod 171 are fixedly connected to the two first connecting seats 111 respectively.
[0058] The above embodiment provides stable support for the rotation of the first lead screw 141 by setting two first connecting seats 111. The sliding trajectory of the first nut 142 is constrained by the cooperation between the first guide rod 171 and the first slide groove 1422, ensuring smooth sliding of the first nut 142. At the same time, the structure of the first connecting seat 111 can also be used to connect and fix the first guide rod 171, eliminating the need for additional guide structures such as linear guide rails that occupy a large amount of space, thus simplifying the guide structure.
[0059] Similarly, in some embodiments, please refer to Figure 2 and Figure 4 The mounting component 13 has second connecting seats 133 at both ends of the second nut 152 along the vertical direction, and the second lead screw 151 is rotatably connected to the two second connecting seats 133 respectively. The second nut 152 has a second sliding groove 1522 extending in the vertical direction. The posture adjustment mechanism 100 also includes a second guide rod 172, which passes through the second sliding groove 1522 in the vertical direction, and its two ends are fixedly connected to the two second connecting seats 133 respectively.
[0060] It is understood that the guide structure provided for the second adjustment component 15 is similar to the guide structure provided for the first adjustment component 14 in the above embodiment, and can achieve similar technical effects, so it will not be described in detail again.
[0061] In some embodiments, please refer to Figure 2The posture adjustment mechanism 100 also includes a first elastic element 181. One end of the first elastic element 181 is connected to the base 11 of the first lead screw 141, and the other end is connected to the first nut 142. The first elastic element 181 is used to apply elastic force to the first nut 142 so that the threads between the first nut 142 and the first lead screw 141 are tightly engaged. For example, when the first lead screw 141 is connected to the base 11 through two first connecting seats 111, the first elastic element 181 can be connected between one of the first connecting seats 111 and the first nut 142.
[0062] The above embodiment, by providing a first elastic element 181, can apply elastic force in the sliding direction of the first nut 142 (i.e., the first horizontal direction), thereby maintaining stable contact between the internal thread of the first nut 142 and the external thread of the first lead screw 141, eliminating the axial gap between the first nut 142 and the first lead screw 141, and thus ensuring the stability of the transmission and the adjustment accuracy.
[0063] Similarly, in some embodiments, please refer to Figure 2 The posture adjustment mechanism 100 also includes a second elastic element 182. One end of the second elastic element 182 is connected to the position of the connecting mounting part 13 of the second lead screw 151, and the other end is connected to the second nut 152. The second elastic element 182 is used to apply a spring force to the second nut 152 so that the second nut 152 abuts against the second lead screw 151. For example, when the second lead screw 151 is connected to the base 11 through two second connecting seats 133, the second elastic element 182 can be connected between one of the first connecting seats 111 and the second nut 152.
[0064] The above embodiment achieves a similar effect to the first elastic element 181 by setting the second elastic element 182, that is, ensuring the stability and adjustment accuracy of the contact transmission between the second nut 152 and the second lead screw 151.
[0065] Considering the weight of the component to be adjusted, the effect of gravity must be overcome when adjusting the pitch angle around the first horizontal axis. In one embodiment, please refer to... Figure 7 A third elastic element 183 can be provided between the lower end of the base 11 and the lower end of the mounting member 13. The third elastic element 183 is used to apply a spring force from the base 11 to the mounting member 13. The torque generated by this spring force on the axis of rotation of the mounting member 13 relative to the adapter 12 can counteract the torque generated by gravity on the same axis, thereby reducing the resistance caused by the gravity of the component to be adjusted when adjusting the pitch angle and improving the convenience of adjustment. At the same time, this arrangement can also prevent the mounting member 13 from sagging under the action of gravity and keep the position of the mounting member 13 stable after rotation adjustment around the first horizontal direction.
[0066] When adopting the above design scheme, the base 11 and the mounting part 13 can be respectively provided with a connecting hole and a connecting post at the position where the third elastic element 183 is connected. The connecting hole is inserted into the connecting post, and the third elastic element 183 is sleeved on the outside of the connecting post. Thus, the direction of the elastic force applied to the third elastic element 183 is limited by the connecting post. At the same time, a certain gap is formed between the connecting hole and the connecting post to allow the mounting part 13 to rotate relative to the base 11 along the vertical axis, so as to avoid restricting the adjustment of the mounting part 13 in the left and right orientation.
[0067] In some embodiments, please refer to Figure 8 , Figure 8 A pose adjustment mechanism 100, different from the embodiments described above, is shown. In this pose adjustment mechanism 100, the first adjustment component 14 includes a first worm 144 and a first worm wheel 145. The first worm 144 is rotatably connected to the base 11 about a first horizontal axis. The first worm wheel 145 meshes with the first worm 144. The axle of the first worm wheel 145 is parallel to the vertical direction, and the first worm wheel 145 is fixedly connected to the adapter 12.
[0068] Similarly, in some embodiments, please refer to Figure 8 The second adjusting assembly 15 includes a second worm 154 and a second worm wheel 155. The second worm 154 is rotatably connected to the mounting member 13 about a vertical axis, and the second worm wheel 155 meshes with the second worm 154. The axle of the second worm wheel 155 is parallel to the first horizontal direction, and the second worm wheel 155 is fixedly connected to the adapter 12.
[0069] In the above embodiments, the first adjustment component 14 and the second adjustment component 15 adopt the form of a worm gear combination, which can also achieve the purpose of adjusting the position of the mounting component 13. It is understood that in specific designs, the specific forms of the first adjustment component 14 and the second adjustment component 15 can usually be flexibly selected. They can adopt the form of a lead screw, nut and connecting rod, or they can adopt the form of a worm gear, which provides high design flexibility.
[0070] In some embodiments, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 9The mounting component 13 includes a first sub-mounting component 134 and a second sub-mounting component 135. The first sub-mounting component 134 is connected to the adapter 12. The second sub-mounting component 135 is rotatably connected to the first sub-mounting component 134 about a second horizontal axis, and is used to mount and fix the component to be adjusted. The posture adjustment mechanism 100 also includes a third adjustment assembly 19, which includes a third lead screw 191 and a third nut 192. The third lead screw 191 is rotatably connected to the first sub-mounting component 134 about a first horizontal axis. The third nut 192 is threadedly connected to the third lead screw 191 to slide along the first horizontal direction under the drive of the third lead screw 191. A third connecting hole 1351 is provided on the second sub-mounting component 135 along the second horizontal direction, and on a plane perpendicular to the second horizontal direction, the third connecting hole 1351 is spaced apart from the axis of rotation of the second sub-mounting component 135 relative to the first sub-mounting component 134. A third connecting post 1921 extending along the second horizontal direction is provided on the third nut 192. The third connecting post 1921 is inserted into the third connecting hole 1351 so that when sliding along the first horizontal direction, it drives the second sub-mounting member 135 to rotate relative to the first sub-mounting member 134. Figure 9 The diagram shows the state during assembly and alignment of the first sub-mount 134 and the second sub-mount 135.
[0071] Specifically, when the third lead screw 191 rotates, the third nut 192 slides along the first horizontal direction and applies a force along the first horizontal direction to the second sub-mount 135 through the third connecting post 1921. Since the second sub-mount 135 is rotatably connected to the first sub-mount 134 around the second horizontal axis, the movement trajectory of the second sub-mount 135 is restricted. Therefore, under the force applied by the third connecting post 1921, the second sub-mount 135 rotates relative to the first sub-mount 134. Through the above movement process, the rotation of the third lead screw 191 can be converted into the rotation of the second sub-mount 135 around the second horizontal axis, thereby driving the adjusted component on the second sub-mount 135 to perform position adjustment.
[0072] To facilitate the application of a rotational force to the third lead screw 191, in one embodiment, such as... Figure 2 As shown, a knob 161 can be fixedly connected to one end of the third lead screw 191. Similarly, the knob 161 connected to one end of the first lead screw 141 and the second lead screw 151 can be rotated by the user to drive the third lead screw 191 to rotate.
[0073] In the above embodiments, the first adjustment component 14 employs a transmission mechanism formed by a first lead screw 141, a first nut 142, and a first connecting rod 143, thereby realizing the rotational adjustment of the mounting component 13 around a vertical axis. The rotation angle of the first lead screw 141 is significantly reduced after multiple stages of transmission via the first nut 142 and the first connecting rod 143. Even if the rotation amplitude of the first lead screw 141 is large, the final rotation amplitude of the mounting component 13 remains small, thus significantly improving the adjustment accuracy and meeting the needs for fine-tuning in some application scenarios.
[0074] It is understood that when the mounting component 13 includes a first sub-mounting component 134 and a second sub-mounting component 135, the second lead screw 151, adapter 12, and other structures connected to the mounting component 13 in the above embodiments are specifically connected to the first sub-mounting component 134. When the first sub-mounting component 134 rotates around the vertical axis under the drive of the first adjustment component 14, or rotates around the first horizontal axis under the drive of the second adjustment component 15, the first sub-mounting component 134 can drive the second sub-mounting component 135 to move synchronously. Only when the third adjustment component 19 outputs power will the second sub-mounting component 135 rotate relative to the first sub-mounting component 134 around the second horizontal axis. This configuration enables the second sub-mounting component 135 to drive the component to be adjusted to rotate and adjust in multiple dimensions around the vertical axis, the first horizontal axis, and the second horizontal axis, meeting the requirements for flexibility in posture adjustment.
[0075] In the above embodiment, based on the first adjustment component 14 and the second adjustment component 15, the mounting component 13 is split into a first sub-mounting component 134 and a second sub-mounting component 135 that can rotate relative to each other, and a third adjustment component 19 is further provided. Without affecting the adjustment function of the first adjustment component 14 and the second adjustment component 15, an adjustment method that allows rotation around a second horizontal axis is further realized, increasing the degree of freedom of adjustment. Furthermore, the rotation angle of the third lead screw 191 is significantly reduced after multiple stages of transmission through the first nut 142 and the second sub-mounting component 135. Even if the first lead screw 141 rotates a large amplitude, the final rotation amplitude of the second sub-mounting component 135 is still small, thus significantly improving the adjustment accuracy and meeting the needs of fine-tuning in some application scenarios.
[0076] Please see Figure 10This application also provides an automotive calibration device 1000, including a base 200 and the posture adjustment mechanism 100 described in the above embodiment, with a base 11 connected to the base 200. Specifically, the automotive calibration device 1000 can be a four-wheel alignment device, an ADAS calibration device, a body straightening device, etc. It is understood that the automotive calibration device 1000 typically also includes necessary detection devices such as a distance measuring instrument and a camera assembly. These detection devices can be fixedly mounted on the mounting component 13, thereby enabling the required posture adjustment under the action of the posture adjustment mechanism to ensure the accuracy of the detection and positioning.
[0077] The automotive calibration device 1000 provided in this application embodiment, by setting up a posture adjustment mechanism 100, makes posture adjustment operation convenient and highly flexible. At the same time, since the first adjustment component 14 and the second adjustment component 15 of the posture adjustment mechanism 100 adopt an integrated design, the overall size is reduced and the compactness is improved. Therefore, the automotive calibration device 1000 has good portability.
[0078] 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. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein; 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.
