Description

Technical Field

[0001] This utility model relates to the field of vehicle technology, and in particular to a surface difference adjustment mechanism, a vehicle body, and a vehicle. Background Technology

[0002] In actual vehicle assembly, various factors such as manufacturing tolerances, displacement during assembly, and temperature changes in materials can lead to suboptimal surface finish between two parts, making adjustment difficult. This is especially true when the dashboard's weight causes it to sink, resulting in a mismatch between the surface finish and the front door panel, making adjustment work even more complex and expensive.

[0003] In related technologies, the surface difference between two parts is mainly adjusted through methods such as mold compensation, adding supports, or limiting. Mold compensation controls the manufacturing tolerances of the parts by adjusting the mold to achieve ideal surface difference matching during assembly. However, this method is only applicable to the design stage. Once production begins, it is difficult to adjust existing surface difference problems in real time, and the cost is high.

[0004] Adding supports refers to improving surface mismatch by adding additional support blocks during part assembly. However, due to the fixed nature of the supports, they lack the ability to adjust for minor changes that occur during assembly.

[0005] Using limiters involves controlling the relative position of two parts by setting limit devices between them to reduce surface differences. However, the design and implementation of limit devices are also complex, and their adjustment range is limited when faced with unexpected assembly changes, making it difficult to achieve high-precision surface difference adjustment.

[0034] The beneficial effects of this utility model are as follows:

[0035] This invention provides a surface difference adjustment mechanism, a vehicle body, and a vehicle. The rotation or sliding of the adjusting component drives the rotation or sliding of the adjusting structure, which moves relative to a second part. The adjusting structure has different height positions in the rotation or sliding direction of the adjusting component. During the movement of the adjusting structure relative to the second part, these different height positions support the second part, ensuring that the second part has different heights relative to the base. By rotating or sliding the adjusting component, the relative height position between the second part and the base can be switched and adjusted, enabling fine-tuning of the surface difference between the first and second parts. This ensures the accuracy of the surface difference adjustment and allows for precise control of the relative positions of the first and second parts, meeting high-precision assembly requirements. Furthermore, the surface difference adjustment mechanism, through the flexible rotation or sliding of the adjusting component, can adapt to surface difference changes under different assembly conditions. Especially during actual vehicle assembly, displacement and deformation of parts due to factors such as weight and temperature changes can be addressed by adjusting the adjusting component, instantly correcting surface differences and reducing repeated disassembly or hardware replacement, greatly improving assembly flexibility and efficiency. This embodiment uses the rotation or sliding of the adjusting component to switch different height positions of the adjusting structure and accurately match the second part, reducing the impact of the adjustment accuracy of the planar surface difference adjustment mechanism, reducing the possibility of operational errors, and making the surface difference adjustment process more efficient and controllable.

[0049] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0050] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0051] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0052] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, 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. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0053] like Figures 1 to 3 As shown, an embodiment of this utility model provides a surface difference adjustment mechanism for adjusting the surface difference between a first part 5 and a second part 6, where the first part 5 and the second part 6 are two parts arranged arbitrarily adjacent to each other. The surface difference adjustment mechanism includes a base 1 and an adjusting member 2. The base 1 can be mounted on the first part 5. The adjusting member 2 is rotatably or slidably mounted on the base 1. The adjusting member 2 is provided with an adjusting structure 21, which extends along the rotation or sliding direction of the adjusting member 2. The adjusting structure 21 has different height positions along the rotation or sliding direction of the adjusting member 2. The second part 6 abuts against the adjusting structure 21. When the adjusting member 2 drives the adjusting structure 21 to rotate or slide, the second part 6 can be located at different height positions of the adjusting structure 21.

[0054] The base 1 serves as a support structure for the adjustment component 2. The base 1 can support the adjustment component 2 away from the surface of the first part 5 or the second part 6, so that the adjustment component 2 has sufficient space for installation and operation.

[0055] The fact that the adjustment structure 21 extends along the rotation or sliding direction of the adjustment member 2 means that the adjustment structure 21 can be arranged on the rotation or sliding path of the adjustment member 2. For example, the adjustment structure 21 can be arranged in the circumference of the adjustment member 2. The rotation of the adjustment member 2 can drive the adjustment structure 21 to rotate. The adjustment member 2 and the adjustment structure 21 rotate around the same axis. The fact that the adjustment structure 21 is arranged along the rotation direction of the adjustment member 2 can reduce the radial displacement generated by the adjustment structure 21 during the rotation of the adjustment member 2.

[0056] In the rotation or sliding direction of the adjusting member 2, the adjusting structure 21 has different height positions, which means that different positions on the surface of the adjusting structure 21 can have different heights. The height of the adjusting structure 21 can refer to the height of the protrusion or the height of the recess.

[0057] When the adjusting member 2 drives the adjusting structure 21 to rotate or slide, the second part 6 can be located at different height positions of the adjusting structure 21. This is because the rotation or sliding of the adjusting member 2 can switch the support position of the second part 6 at different height positions of the adjusting structure 21, so that the second part 6 has different heights.

[0058] With this configuration, the surface difference adjustment mechanism can be located at the matching position of the first part 5 and the second part 6. The rotation or sliding of the adjusting member 2 can drive the adjusting structure 21 to rotate or slide. The adjusting structure 21 will slide relative to the second part 6. The adjusting structure 21 has different height positions in the rotation or sliding direction of the adjusting member 2. During the sliding process of the adjusting structure 21 relative to the second part 6, the different height positions of the adjusting structure 21 can support the second part 6 respectively, so that the second part 6 has different heights relative to the base 1. By switching and adjusting the relative height position between the second part 6 and the base 1 through the rotation or sliding of the adjusting member 2, the surface difference between the first part 5 and the second part 6 can be finely adjusted, thereby ensuring the accuracy of surface difference adjustment and finely controlling the relative position of the first part 5 and the second part 6 to meet the requirements of high-precision assembly. Furthermore, the surface difference adjustment mechanism, through the flexible rotation or sliding of the adjusting component 2, can adapt to surface difference changes occurring under different assembly conditions. Especially during actual vehicle assembly, displacement and deformation of parts due to weight, temperature changes, and other factors can be addressed by adjusting the adjusting component 2. This allows for immediate correction of surface differences, reducing the need for repeated disassembly or hardware replacement, significantly improving assembly flexibility and efficiency, and facilitating adjustment. In this embodiment, the rotation or sliding of the adjusting component 2 switches between different height positions of the adjusting structure 21 to accurately match the second part 6, reducing the impact of the adjustment accuracy of the surface difference adjustment mechanism and lowering the possibility of operational errors. This makes the surface difference adjustment process more efficient and controllable. It can flexibly adjust the surface difference between adjacent parts within a certain range according to the matching status of parts in actual vehicles and other equipment. It is suitable for areas with unstable and difficult-to-adjust surface differences, solving the technical problems of inconvenient surface difference adjustment and low adjustment accuracy between two parts in related technologies.

[0059] Optionally, the adjusting structure 21 of the adjusting member 2 can be designed with multiple stepped sections of different heights. Each stepped section corresponds to a specific surface difference adjustment amount. By precisely controlling the rotation angle of the adjusting member 2, the adjusting structure 21 can be adjusted to the required stepped section, thereby performing multi-level height adjustment and achieving more precise surface difference adjustment. It can also meet the precise control of different surface difference adjustment requirements. In addition, the adjusting structure 21 can be, but is not limited to, a protruding structure or a groove structure, both of which can adjust the second part 6. Similarly, the second part 6 can directly abut against the adjusting structure 21, or the second part 6 can also have a groove structure or a protruding structure, etc., to abut against the adjusting structure 21, so that the second part 6 can be positioned at different height positions of the adjusting structure 21.

[0060] The surface of the adjustment structure 21 may be provided with tiny grooves or textures to improve the fit and friction between the second part 6 and the adjustment structure 21, prevent slippage, and enhance the stability of the adjustment process. Magnetic adsorption structures may be provided around the adjustment structure 21 and on the second part 6. After the second part 6 is adjusted to the predetermined position and external force is removed, the magnetic adsorption structure between the adjustment structure 21 and the second part 6 increases their positional stability, prevents accidental movement, and ensures the stability of the adjusted state.

[0061] Optionally, the rotation or sliding of the adjusting member 2 can be driven manually by the user. Alternatively, the surface difference adjustment mechanism may also include an adjusting drive member, which is connected to the adjusting member 2 to drive the adjusting member 2 to rotate or slide. The adjusting drive member can be, but is not limited to, a motor, a cylinder, or a hydraulic cylinder, as long as it can drive the adjusting member 2 to rotate or slide. In addition, the adjusting drive member can also be connected to the control system on the vehicle or production line to allow the user to remotely control the surface difference adjustment mechanism and improve assembly efficiency. The surface difference adjustment mechanism may also include a surface difference detection member, which is used to detect the actual surface difference value between the first part 5 and the second part 6, so that the user can obtain standard data of the actual surface difference value between the first part 5 and the second part 6 in real time, reducing errors from manual evaluation by different users and over-adjustment. The surface difference detection member can be used in conjunction with the adjusting drive member and the control system to form an automatic feedback mode for surface difference adjustment, which can automate the surface difference adjustment process, reduce human error, improve the intelligence level of the assembly line, and reduce production costs. The surface difference detection member can be, but is not limited to, a position sensor or a vision inspection system.

[0062] like Figures 3 to 5As shown, in some embodiments, the second part 6 has a protruding structure 61 that abuts against the adjusting structure 21. The adjusting structure 21 is an annular boss, and the protruding structure 61 abuts against the top of the annular boss. That is, the annular boss, as the adjusting structure 21, provides a stable support platform and movement trajectory. Because the protruding structure 61 abuts against the top of the annular boss, the gap between the protruding structure 61 and the adjusting structure 21 is reduced, decreasing the swaying and vibration that may occur when adjusting surface differences. This ensures that the protruding structure 61 moves along the expected path relative to the adjusting structure 21, reducing unnecessary offsets and thus improving the accuracy of surface difference adjustment. The abutment between the protruding structure 61 and the top of the annular boss ensures that the protruding structure 61 can be repeatedly positioned at the same height each time it is adjusted to the same height. This significantly improves the accuracy of repeated positioning and reduces errors between parts in situations requiring frequent surface difference adjustments, such as assembly on a production line. Moreover, the annular boss structure can evenly distribute the weight and pressure of the protruding structure 61, avoiding excessive local stress, improving the load-bearing capacity and durability of the entire surface difference adjustment mechanism, and ensuring the structural stability and reliability under long-term use.

[0063] Alternatively, the adjustment structure 21 can be a wedge-shaped boss, with the protruding structure 61 abutting against the inclined surface of the wedge-shaped boss. The wedge-shaped boss can also provide a stable support platform for the protruding structure 61, allowing the protruding structure 61 to slide along the inclined surface of the wedge-shaped boss, reducing unnecessary offset. The movement of the protruding structure 61 is stable, improving the surface difference adjustment accuracy.

[0064] Optionally, the surfaces of the raised structure 61 and the adjustment structure 21 may also be provided with a wear-resistant layer. The wear-resistant layer may be, but is not limited to, a wear-resistant metal plating layer, an oxide layer or a wear-resistant spraying layer, in order to increase the wear resistance of the surfaces of the raised structure 61 and the adjustment structure 21 and reduce friction and wear during the adjustment process.

[0065] Optionally, the adjusting structure 21 and the adjusting component 2 can be integrally formed, which can increase the positional stability of the adjusting structure 21. Alternatively, the adjusting structure 21 and the adjusting component 2 can be designed as separate structures, and a height adjustment structure can be provided between the adjusting structure 21 and the adjusting component 2 to adjust the overall height of the adjusting structure 21. For example, the height adjustment structure may include adjustable shims or a lifting platform, which can adjust the overall height of the adjusting structure 21 relative to the adjusting component 2.

[0066] Optionally, the connection between the base 1 and the first part 5, as well as the joint between the protruding structure 61 and the second part 6, can be integrally formed, which facilitates improving the positional stability between the base 1 and the first part 5, between the protruding structure 61 and the second part 6, and between the adjusting structure 21 and the protruding structure 61. Alternatively, the connection between the base 1 and the first part 5, as well as the joint between the protruding structure 61 and the second part 6, can also be a detachable connection such as a bolt connection, snap-fit ​​connection, or magnetic connection, which facilitates installation on different parts and adjustment of surface differences between different parts. According to the actual vehicle assembly, the surface difference can be flexibly adjusted without affecting the assembly, performance, appearance, etc.

[0067] Optionally, the protruding structure 61 and the adjusting structure 21 can be arranged in a one-to-one correspondence, and multiple groups can be provided. The adjusting structure 21 in the multiple groups can be arranged at different radial positions of the adjusting member 2 to form different adjustment paths. Multiple groups of protruding structures 61 and adjusting structures 21 can be used selectively to perform surface difference adjustment within different height ranges. Alternatively, multiple groups of protruding structures 61 and adjusting structures 21 can be used together to adjust the surface difference of different positions to be adjusted on one part relative to another part. For example, the first part 5 may have multiple surfaces to be adjusted, and the protruding structures 61 in the multiple groups can be respectively arranged on the surfaces to be adjusted. The difference in different height positions between the multiple groups of adjusting structures 21 can be preset according to the height difference between the surface to be adjusted and the reference surface of the second part 6. By rotating or sliding the adjusting member 2, the surface difference between multiple surfaces to be adjusted on the first part 5 and the reference surface of the second part 6 can be adjusted together, so that the surface difference adjustment mechanism can adapt to more complex adjustment needs and improve the flexibility and efficiency of adjustment.

[0068] like Figures 2 to 3As shown, in some embodiments, the height of the annular boss gradually increases or decreases in the rotation or sliding direction of the adjusting member 2, or the height of the inclined surface of the wedge-shaped boss gradually increases or decreases in the sliding direction of the adjusting member 2. This gradual change in height allows the adjusting member 2 to automatically adjust the vertical position of the protruding structure 61 in contact with the adjusting structure 21 according to the rotation or sliding position during rotation or sliding. This enables minute, continuous changes, thereby achieving continuous and precise adjustment of the surface difference between the first part 5 and the second part 6, covering a large adjustment range. The compact adjusting structure 21 effectively saves space while maintaining a smooth and controllable adjustment process, improving the accuracy and flexibility of surface difference adjustment. During rotation or sliding, the smooth transition of the contact surface between the adjusting member 2 and the adjusting structure 21 reduces vibration and impact, helping to maintain stable contact between the adjusting structure 21 and the protruding structure 61, avoiding surface difference adjustment errors caused by unstable movement. When the height of the protrusion of the adjustment structure 21 gradually increases or decreases in the rotation or sliding direction, the adjustment component 2 can automatically find a suitable protrusion height position according to the actual required surface difference adjustment amount, realize adaptive adjustment, without the need for additional tools or human intervention, simplify the adjustment process and improve efficiency.

[0069] Optionally, the slope of the height change of the annular boss can be selected according to the surface difference adjustment requirements between the first part 5 and the second part 6. For example, if the surface difference change between the first part 5 and the second part 6 is small, the annular boss can be designed with a gentler slope to achieve finer adjustment; conversely, if a large adjustment of the surface difference between the first part 5 and the second part 6 is required, the annular boss can be designed with a steeper slope to cover a larger adjustment range.

[0070] Optionally, the height difference between the lowest and highest positions of the annular or wedge-shaped boss can be equal to or less than 2 mm. Taking the height difference of the annular boss as an example, the height difference between the lowest and highest positions of the annular boss can be selected as 1 mm, 1.5 mm or 2 mm.

[0071] When the height difference between the lowest and highest positions of the annular boss is selected to be 1 mm, the small height difference means that each rotation angle change will bring about a small change in surface difference. This is suitable for applications requiring extremely high precision adjustment, such as precision electronic equipment and optical instruments. Furthermore, the small height difference means a smaller adjustment step size, which helps to improve the accuracy of repeatability and ensure the consistency of surface difference adjustment.

[0072] When the height difference between the lowest and highest positions of the annular boss is selected to be 1.5 mm, it balances accuracy and efficiency. Compared to 1 mm, a height difference of 1.5 mm provides a larger adjustment range without significant loss of accuracy, making it suitable for applications requiring a balance between accuracy and adjustment speed. Furthermore, it allows for greater surface difference variation in a single rotation, providing a wider adjustment range and reducing the need for multiple operations.

[0073] When the height difference between the lowest and highest positions of the annular boss is selected as 2 mm, this 2 mm height difference allows for a significant change in surface difference during a single rotation of the adjusting component 2, making it suitable for applications requiring a large adjustment range. Due to the larger adjustment range, users can adjust to the target surface difference state more quickly, improving operational convenience and efficiency. A 2 mm height difference ensures a certain level of accuracy while meeting the surface difference adjustment needs of most assembly applications. A height difference greater than 2 mm is more suitable for applications requiring significant surface difference adjustment with relatively lower precision requirements, such as large-scale mechanical assembly or preliminary calibration. The 2 mm height difference selection represents a relative balance, ensuring adjustment range and operational efficiency while meeting the precision requirements of most assembly applications, making it suitable for common surface difference adjustment situations in actual vehicle assembly.

[0074] like Figures 6 to 7 As shown, in some embodiments, the surface difference adjustment mechanism further includes a stop component 4, which is disposed between the base 1 and the adjusting member 2. The adjusting member 1 can be selectively locked to the base 1 through the stop component 4. When the adjusting member 2 rotates or moves to switch the protruding structure 61 of the second part 6 to a suitable height position, in addition to being fixed by the friction between the protruding structure 61 of the second part 6 and the adjusting structure 21, the stop component 4 can also be used to further lock the base 1 and the adjusting member 2, thereby further fixing the position of the adjusting member 2, thus ensuring the stability of the surface difference adjustment, reducing the surface difference changes caused by unexpected situations such as vibration, and maintaining the stable state of the surface difference after adjustment.

[0075] In some embodiments, the stop assembly 4 includes a stop pin 41, a plurality of stop mating parts 42, and an elastic member 43. The stop pin 41 is slidably disposed on the base 1, and the stop mating parts 42 are disposed on the adjusting member 2, with the plurality of stop mating parts 42 spaced apart along the rotation or sliding direction of the adjusting member 2. The elastic member 43 is disposed between the stop pin 41 and the base 1, and the elastic member 43 can apply a force to the stop pin 41 toward the stop mating parts 42, allowing the stop pin 41 to selectively engage with any of the stop mating parts 42. The connection between the stop pin 41 and the stop mating parts 42 provides a precise positioning point. When the stop pin 41 is accurately connected to one of the stop mating parts 42, the position of the adjusting member 2 can be fixed, thereby ensuring the stability of the surface difference adjustment, reducing surface difference changes caused by unexpected situations such as vibration, and maintaining a stable state of the surface difference after adjustment. Since the stop fitting parts 42 are spaced apart along the rotation or sliding direction of the adjusting member 2, each stop fitting part 42 represents a preset surface difference adjustment position, allowing the user to precisely adjust the surface difference according to the set increment or decrement, thus improving the overall adjustment accuracy. The elastic member 43 not only pushes the stop pin 41 to maintain a tight connection with the stop fitting part 42, but also provides sufficient movement space for the stop pin 41 when the adjusting member 2 rotates or slides to separate the stop pin 41 from the stop fitting part 42. This reduces the user's manual pushing and pulling operation of the stop pin 41; only rotating or sliding the adjusting member 2 is needed to connect or separate the stop pin 41 from the stop fitting part 42, making the operation simple. In this embodiment, by using the stop assembly 4, the precise engagement of the stop pin 41 and the stop fitting part 42 can reduce the surface difference adjustment error caused by the user's manual positioning or visual judgment error, and reduce the impact of human factors on the surface difference adjustment accuracy.

[0076] Optionally, multiple stop-fitting parts 42 can be equally spaced along the rotation or sliding direction of the adjusting member 2, with each stop-fitting part 42 corresponding to a different surface difference adjustment level. Alternatively, the multiple stop-fitting parts 42 can also be unequally spaced along the rotation or sliding direction of the adjusting member 2 to provide surface difference variations of different lengths according to actual needs. For example, taking the rotation mode of the adjusting member 2 as an example, the spacing of the stop-fitting parts 42 is smaller during the first 180° of rotation of the adjusting member 2, providing more precise adjustment. During the last 180° of rotation of the adjusting member 2, the spacing of the stop-fitting parts 42 is larger, facilitating rapid and wide-range adjustment, improving the flexibility of surface difference adjustment, allowing for both fine-tuning when needed and rapid wide-range adjustment, suitable for various adjustment scenarios. In this embodiment, 12 stop-fitting parts 42 can be provided, and the multiple stop-fitting parts 42 can be equally spaced.

[0077] Optionally, both the stop pin 41 and the stop mating part 42 can be made of magnetic materials. For example, the front end or the entire stop pin 41 can be set as a magnetic pin segment, and the stop mating part 42 can also be a magnetic block. That is, the stop pin 41 and the stop mating part 42 can be connected or reinforced by magnetic attraction. The connection and separation operations of the two are more convenient. When the stop pin 41 and the stop mating part 42 are connected, the magnetic force can lock the stop pin 41 to prevent it from accidentally moving out under vibration or external force, which increases the locking strength of the stop assembly 4 and improves the anti-interference ability during the adjustment process.

[0078] Optionally, the elastic element 43 can be an adjustable elastic element 43, allowing the user to adjust the preload of the elastic element 43 according to actual needs, thereby changing the locking strength between the stop pin 41 and the stop mating part 42. This allows for adjustment of the locking strength according to different surface differences, ensuring effective locking under various operating conditions. For example, the elastic element 43 can be a spring with a bolt at its bottom, which can be threaded to the base 1. The preload of the spring can be adjusted by rotating the bolt.

[0079] Optionally, the stop pin 41 is designed as a cone or wedge, and the stop mating part 42 is designed as a matching inverted cone or inverted wedge. This allows it to self-align during insertion and reduces wear during removal, thereby increasing the service life of the stop assembly 4 and reducing the frequency of maintenance and replacement. At the same time, the self-aligning function improves the ease of operation.

[0080] Optionally, the stop assembly 4 may also include a stop position detection element, which is used to detect the stop locking position of the stop pin 41. The stop position detection element may be, but is not limited to, an infrared sensor or a radar sensor. The stop position detection element may be set inside the stop mating part 42 and is triggered when the stop pin 41 is connected to the stop mating part 42. The stop position detection element may also be connected to the control system on the vehicle or production line to provide real-time feedback on the stop locking position of the stop pin 41, so that the user can obtain the surface difference position corresponding to the stop locking position of the stop pin 41. It can even be automatically adjusted to the preset surface difference position for locking through the closed-loop control system, thereby improving the accuracy and efficiency of operation.

[0081] like Figures 6 to 7As shown, in some embodiments, the base 1 includes a base body 11 and a pressure plate 12. The base body 11 is provided with a receiving groove 111. The pressure plate 12 is detachably disposed at the opening of the receiving groove 111. One end of the stop pin 41 is disposed in the receiving groove 111 and the stop pin 41 is slidably connected to the pressure plate 12. The elastic member 43 is disposed between the stop pin 41 and the receiving groove 111. With this configuration, by providing the receiving groove 111 in the base body 11, the stop pin 41 is limited to the receiving groove 111, ensuring that it can only move in a predetermined direction. This avoids disordered movement or offset of the stop pin 41 during operation, improves the accuracy and reliability of the matching between the stop pin 41 and the stop fitting part 42 on the adjusting member 2, and thus ensures the accuracy of the surface difference adjustment. The elastic element 43 is disposed between the stop pin 41 and the receiving groove 111, and can apply a preload force to the stop pin 41, ensuring that the stop pin 41 is always in contact with the stop mating part 42 when no external force is applied. This helps the stop pin 41 to quickly and accurately engage with the stop mating part 42, reducing operation waiting time and improving the efficiency of surface difference adjustment operation. The pressure plate 12 is detachably disposed at the opening of the receiving groove 111 and is slidably connected to the stop pin 41, allowing the user to easily remove the pressure plate 12 when needed, facilitating the inspection, maintenance, or replacement of the stop pin 41. The detachability of the pressure plate 12 also allows for convenient adjustment when the stop pin 41 is worn or the elastic element 43 needs to be replaced, without affecting the use of the entire surface difference adjustment mechanism, improving the maintainability and service life of the equipment. Moreover, the user can replace the stop pin 41 with different lengths or the elastic element 43 with different elastic strengths according to the needs of use, to adapt to different surface difference adjustment ranges and force requirements.

[0082] Optionally, the connection between the pressure plate 12 and the seat body 11 can be, but is not limited to, a magnetic connection, a snap-fit ​​connection, or a quick-release screw, making it easier to replace or adjust the pressure plate 12, saving assembly and maintenance time, and improving work efficiency. The elastic element 43 can be, but is not limited to, a spring, elastic rubber, pneumatic or hydraulic elastic element, etc., to provide the required preload and rebound force. The stop pin 41 can be made of a high-hardness, wear-resistant material, such as alloy steel or ceramic material, to ensure the stability and accuracy of the stop pin 41 in long-term use, improve the durability and reliability of the surface difference adjustment mechanism, and reduce the surface difference adjustment error caused by the wear of the stop pin 41.

[0083] like Figures 6 to 7As shown, in some embodiments, the stop pin 41 is provided with an anti-detachment part 411, which is located in the receiving groove 111 and can abut against the pressure plate 12. The elastic member 43 is sleeved on the stop pin 41 and clamped between the anti-detachment part 411 and the bottom wall of the receiving groove 111. The anti-detachment part 411 can reduce the possibility of the stop pin 41 falling off the base 1 during adjustment. Even if the user applies a large force or the equipment encounters unexpected vibration, the stop pin 41 can remain on the base 1, avoiding adjustment failure or assembly error caused by the stop pin 41 falling off. The elastic member 43, clamped between the anti-detachment part 411 and the bottom wall of the receiving groove 111, can stably support the stop pin 41. When the stop pin 41 is not connected to the stop mating part 42, the preload force of the elastic element 43 can also ensure that the stop pin 41 remains in contact with the bottom of the adjusting part 2. This helps the stop pin 41 to quickly identify the stop mating part 42 when the adjusting part 2 rotates or slides, and the stop pin 41 can be positioned quickly and accurately, improving the speed and accuracy of surface difference adjustment. The cooperative use of the anti-detachment part 411 and the elastic element 43 reduces the wear and deformation of the stop pin 41, extends the service life of the stop pin 41, and reduces the maintenance frequency and replacement cost of the stop pin 41 during long-term operation of surface difference adjustment.

[0084] Optionally, the anti-detachment part 411 can be provided on the circumferential side of the stop pin 41. The anti-detachment part 411 can be, but is not limited to, a flange or a protrusion structure. Alternatively, the anti-detachment part 411 can be a stepped structure on the side wall of the stop pin 41 to ensure the stability of the stop pin 41 within its maximum stroke range and prevent it from falling off. The anti-detachment part 411 can be integrally formed with the stop pin 41, or the anti-detachment part 411 can be threaded or snap-fitted to the stop pin 41 to adjust the position of the anti-detachment part 411 on the stop pin 41, thereby adjusting the extendable length of the stop pin 41 to meet the requirements of different surface difference adjustment ranges.

[0085] like Figures 6 to 7 As shown, in some embodiments, the end of the stop pin 41 is provided with a first guide surface 412, and / or the stop mating part 42 is provided with a stop groove, and the opening of the stop groove is provided with a second guide surface 421. The provision of the guide surface helps to guide the stop pin 41 to be accurately aligned and inserted into the stop groove. Even when there is a slight offset when the user rotates or slides the adjustment part 2, the first guide surface 412 and the second guide surface 421 can also play the role of automatic alignment adjustment between the stop pin 41 and the stop groove, so that the stop pin 41 can be smoothly inserted into the stop groove, reducing the frictional resistance between the stop pin 41 and the stop groove during the insertion process, reducing the wear of the stop pin 41 and the stop groove, improving assembly efficiency and ease of operation, and reducing the difficulty of operation.

[0086] Optionally, the shapes of the first guide surface 412 and the second guide surface 421 may be, but are not limited to, V-shaped, U-shaped or hemispherical, to accommodate different insertion angles and operating conditions.

[0087] like Figures 5 to 7 As shown, in some embodiments, a rivet 14 is provided on the base 1, and the adjusting member 2 is rotatably connected to the rivet 14. That is, the base 1 can be rotatably connected to the adjusting member 2 through the rivet 14. The rivet 14 can serve as the rotation center of the adjusting member 2, and the adjusting structure 21 can also be set with the rivet 14 as the center, so that the adjusting member 2 is riveted to the base 1 and can rotate relative to it. The riveting provides stronger physical fixation and impact resistance, ensuring that the surface difference adjustment mechanism remains stable during long-term use and is not easily displaced due to vibration or operational impact. An elastic washer 3 is provided between one end of the adjusting member 2 and the rivet 14, and / or, between the adjusting member 2 and the base 1, and / or, between the base 1 and the other end of the rivet 14. That is, the elastic washer 3 can be selectively set at three positions: between one end of the adjusting member 2 and the rivet 14, between the adjusting member 2 and the base 1, and between the base 1 and the other end of the rivet 14. The use of elastic shims 3 can absorb vibrations and impacts generated during operation, especially the collision between the stop pin 41 and the stop mating part 42 during adjustment, reducing damage to the adjusting component 2 and the base 1 itself, and extending the service life of the mechanism. Furthermore, elastic shims 3 can fine-tune the gap between the adjusting component 2 and the base 1, ensuring precise positioning of the adjusting component 2 during operation, and also reducing direct contact between metal parts, lowering wear and friction. Even under high load or frequent operation environments, it can maintain the smooth and stable rotation of the adjusting component 2, reducing maintenance requirements.

[0088] Optionally, the elastic shim 3 can be disposed between the end of the fastener and the surface of the adjusting member 2, and between the surface of the adjusting member 2 and the surface of the base 1, to facilitate stable rotation of the adjusting member 2. The material of the elastic shim 3 can be, but is not limited to, rubber, silicone, or shape memory alloy. The elastic shim 3 can also be designed as a double-layer structure. For example, the elastic shim 3 may include a stacked elastic layer and a rigid layer. The elastic layer is used to absorb vibration and impact, and the rigid layer is used to fine-tune the position of the adjusting member 2, providing better positioning accuracy and operational stability.

[0089] like Figures 4 to 6As shown, in some embodiments, the base 1 has an opening 13, and the adjusting member 2 is partially disposed within the opening 13. The adjusting member 2 can extend from one side of the base 1 to the other side. Since the adjusting member 2 can extend from both sides of the base 1, the user can choose to adjust from either side of the base 1 according to the actual working environment, greatly improving the flexibility and convenience of surface difference adjustment in narrow or confined spaces. When the operator cannot directly contact or observe one side of the adjusting member 2, operation can be performed from the other side, reducing safety risks during operation. Furthermore, the opening 13 on the base 1 also provides sufficient space for the adjusting member 2 in the radial direction, allowing the user to optimize the size and shape of the adjusting member 2 according to actual application needs to improve the efficiency and effectiveness of surface difference adjustment.

[0090] Optionally, the shape of the opening 13 can be set according to the through portion of the adjusting member 2, and the size of the opening 13 can be larger than the size of the through portion of the adjusting member 2 to reduce positional interference between the two.

[0091] like Figures 5 to 7 As shown, in some embodiments, the adjusting member 2 is a disc structure, and / or, an anti-slip portion 22 is provided on the circumferential sidewall of the adjusting member 2. The disc structure of the adjusting member 2 provides uniform rotational resistance and a stable rotation center, enabling accurate and uniform changes in the surface difference adjustment amount with each rotation, thereby improving the accuracy of surface difference adjustment. Furthermore, the symmetry and stability of the disc structure are superior to other asymmetrical shapes of the adjusting member 2, resulting in stronger self-balancing ability during rotation, reducing operational errors caused by uneven rotation, and improving operational stability and the consistency of surface difference adjustment. The disc structure of the adjusting member 2 provides a larger contact area for the user, allowing for easier control of the rotational force during adjustment and preventing over- or under-adjustment due to improper force. The anti-slip portion 22, such as grooves, protrusions, or textures, on the circumferential sidewall of the adjusting member 2 increases the friction between the user and the adjusting member 2, ensuring stable control of the adjusting member 2 even with wet hands or while wearing gloves, thus improving operational safety and comfort. The disc-shaped adjusting component 2 and anti-slip part 22 are designed to evenly distribute the stress generated during rotation, reduce wear at the contact point between the adjusting component 2 and the base 1, thereby extending the service life of the surface difference adjustment mechanism and reducing maintenance costs.

[0092] Optionally, the anti-slip part 22 can be integrally formed with the adjusting part 2. The material of the anti-slip part 22 can be, but is not limited to, high-friction rubber, silicone or coating, to increase the friction with the user contact surface, while ensuring the durability and low wear characteristics of the material, and extending the service life of the surface difference adjustment mechanism.

[0093] A second aspect of this utility model provides a vehicle body including two adjacent panels. The vehicle body also includes the surface difference adjustment mechanism described in any of the above embodiments. One of the two panels is a first part 5, and the other panel is a second part 6. A base 1 and an adjusting member 2 are disposed on one panel, and the other panel abuts against the adjusting structure 21 of the adjusting member 2. When the adjusting member 2 drives the adjusting structure 21 to rotate or slide, the other panel can be located at different height positions of the adjusting structure 21, thereby adjusting the surface difference between the two adjacent panels on the vehicle body. The two adjacent panels can be any two adjacent panels on the vehicle body, for example, between a door sheet metal and a frame sheet metal, or between different parts of the frame sheet metal.

[0094] Since the surface difference adjustment mechanism described above is included, the vehicle body of this utility model embodiment has all the advantages and beneficial effects of the above embodiments, which will not be repeated here.

[0095] A third aspect of this utility model provides a vehicle including two adjacent panels. The vehicle also includes a surface difference adjustment mechanism as described in any of the above embodiments. One of the two panels is a first part 5, and the other is a second part 6. A base 1 and an adjusting member 2 are disposed on one panel, and the other panel abuts against the adjusting structure 21 of the adjusting member 2. When the adjusting member 2 drives the adjusting structure 21 to rotate or slide, the other panel can be located at different height positions of the adjusting structure 21, enabling adjustment of the surface difference between any two adjacent panels on the vehicle. The two adjacent panels can be any two adjacent panels on the vehicle, for example, between adjacent interior panels, or between an interior panel and a door.

[0096] For example, one of the two panels is the dashboard and the other is the front door panel. The base 1 and the adjusting member 2 are set on the dashboard, and the protruding structure 61 is set on the front door panel. The protruding structure 61 abuts against the adjusting structure 21 of the adjusting member 2. When the adjusting member 2 drives the adjusting structure 21 to rotate or slide, the protruding structure 61 can be located at different height positions of the adjusting structure 21, so as to adjust the surface difference between the dashboard and the front door panel.

[0097] Since the surface difference adjustment mechanism described above is included, the vehicle of this utility model embodiment has all the advantages and beneficial effects of the above embodiments, which will not be repeated here.
