Description

Technical Field

[0001] This utility model relates to the field of automotive parts, and in particular to the field of adjustment components, specifically an adaptive adjustment component for concealing door handles. Background Technology

[0002] The gap between the car body and the sheet metal needs to be uniform and meet assembly tolerance requirements to ensure the flatness of the car body appearance and the stability of the structure. Gaps that are too large, too small, or even uneven may indicate problems with the car body assembly, thus affecting the overall structural stability of the car body.

[0003] Most existing structures require manual adjustment, which is costly. Manual adjustment relies on the operator's skills and experience, thus introducing human error. Furthermore, differences in skill levels and experience can lead to inconsistencies in the manual adjustment of gaps, making it impossible to guarantee the connection stability of each batch of vehicles and posing a driving safety hazard. In addition, since manual adjustment requires measuring and adjusting the gaps one by one, the entire adjustment process can be time-consuming.

[0004] The prior art discloses a tolerance compensation device and a method for assembling and disassembling a concealed door handle. Patent number CN119244620A discloses a tolerance compensation device comprising: a tolerance adjustment seat, including a base plate and an elastic claw connected to the outer side of the base plate, with a first through hole formed on the base plate; a spiral sleeve disposed on the base plate, the outer wall of the spiral sleeve having a spiral groove, and a receiving cavity formed at the end of the spiral sleeve away from the base plate, with a second through hole formed at the bottom of the receiving cavity; and a bolt assembly, including a locking nut, a screw, and a stop head, the screw passing through the first and second through holes. The stop head is connected to one end of the screw rod near the base plate, and the locking nut is threaded to the other end of the screw rod. There is rotational resistance between the locking nut and the screw rod. The end of the base plate away from the spiral sleeve forms a locking part for limiting the rotation of the stop head. An elastic element is provided on the spiral sleeve and connected to the locking nut. This application also provides a method for assembling and disassembling a concealed door handle. It adopts a convenient and detachable structure to realize the simple assembly and disassembly of the door handle, which greatly improves production and maintenance efficiency. Although the fields are the same, the overall structure is different. The structure of the nut, the body and the adjusting shell are not disclosed.

[0005] A tolerance compensator and assembly assembly are disclosed in the prior art (patent number CN219035215U), relating to the field of compensator technology. The tolerance compensator includes a first compensating element and a second compensating element. The first compensating element includes a fixing member, a fastener, a snap-fit ​​member, and a locking member. The fastener has a mounting cavity and a through hole. The snap-fit ​​member is located within the mounting cavity and has a first type of thread structure internally. The locking member has a second type of thread structure externally that mates with the first type of thread structure. The fixing member passes sequentially through the through hole and the snap-fit ​​member and engages with the locking member threadedly. The second compensating element has an elastic adjustment portion that abuts against the inner wall of the mounting cavity. The locking member passes through the second compensating element. One end of the second compensating element abuts against the fastener, and the other end abuts against the snap-fit ​​member. The tolerance compensator provided in this application avoids the situation in the prior art where welding nuts to the parts leads to low assembly efficiency and easy detachment, thus improving assembly efficiency and reliability. Although the fields are the same, it is used for locking and fixing between the hidden door handle and the door sheet metal; however, the locking and adjustment structures are different, involving more parts and being more complex.

[0006] A prior art patent, CN116498165A, discloses a tolerance adjuster for automotive door handles. The adjuster includes a first adjusting block and a second adjusting block. The first adjusting block has a first connecting cavity corresponding to the second adjusting block, and a limiting protrusion is provided within the first connecting cavity. The outer side of the second adjusting block has a guide groove corresponding to the limiting protrusion, and the guide groove is spirally shaped. The second adjusting block rotates forward, causing the limiting protrusion to slide within the guide groove, thus moving the second adjusting block downwards within the first connecting cavity. The upper end of the guide groove... A locking part is provided to limit the locating protrusion from the guide groove. The second adjusting block is connected to an adjusting component that can drive it to rotate. The locating protrusion and the locking part are connected and cooperated. No additional internal or external threads are required on the first and second adjusting blocks, which simplifies the processing technology. Moreover, after the second adjusting block is connected to the first connecting cavity, the number of rotations required is also less, which helps to improve the assembly efficiency of workers. Although the fields are the same and the combination structure of the three kits is also the same, the assembly structure is different, the actual function is different, and there are significant differences in the body. Summary of the Invention

[0007] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide an adaptive adjustment component for concealing door handles, so as to solve the difficulties of the prior art.

[0008] To achieve the above and other related objectives, this utility model provides an adaptive adjustment component for concealing door handles, comprising an adjustment body 1, an inner bolt 2, and an adjustment housing 3 arranged coaxially;

[0009] The adjusting body 1 has an axial opening at one end to form a mounting end 11 for mounting the adjusting housing 3, and a bolt mounting hole 12 for mounting the inner bolt 2 is provided at the other end.

[0010] The nut portion of the inner bolt 2 is located inside the adjusting body 1, and the screw portion passes through the bolt mounting hole 12. During installation, the screw portion passes through the upper sheet metal 4 for locking.

[0011] The top of the adjusting housing 3 is inserted into the adjusting body 1 and installed and locked in place. The adjusting housing 3 is installed on the end of the adjusting body 1 away from the inner bolt 2.

[0012] The outer periphery of the adjusting body 1 and the adjusting housing 3 is provided with a continuous anti-detachment structure.

[0013] Furthermore, the outer diameter of the nut of the inner bolt 2 is larger than the inner diameter of the bolt mounting hole 12, and the length of the adjusting body 1 is greater than the height of the nut portion of the inner bolt 2.

[0014] Furthermore, the outer diameters of the adjusting body 1 and the adjusting housing 3 are the same.

[0015] In this technical solution, considering that the adjusting body 1 and the adjusting housing 3 can be easily adjusted by the inner bolt 2 after installation, it is necessary to use a snap-fit ​​installation structure to ensure that the adjusting body 1 and the adjusting housing 3 can be locked together. The anti-detachment structure of the adjusting body 1 and the adjusting housing 3 can be used to lock them together with the upper and lower sheet metal after installation to prevent loosening.

[0016] After installation, when the product is locked to the customer's sheet metal, the inner bolt 2 of the adjustment circle locks with the upper sheet metal. The adjustment body 1 is subjected to the positive locking force after locking, and the adjustment housing 3 is subjected to the reverse thrust force by the reverse thrust structure. This locks the adjustment body 1 and the adjustment housing 3 with positive and negative forces, locking the product to the lower sheet metal, thereby infinitely adjusting the gap between the body and the door handle to ensure the stability of the body structure.

[0017] According to the preferred embodiment, adjusting body 1 includes:

[0018] The upper body 13 is arranged in a ring shape, with an opening at the bottom and an interior cavity for accommodating the inner bolt 2. The top extends towards the center to form a horizontal upper plane 14.

[0019] Bolt mounting hole 12, the bolt mounting hole 12 is formed on the central axis of the upper plane 14;

[0020] Anti-rotation mounting hole 15, the anti-rotation mounting hole 15 is opened on the upper plane 14 around the bolt mounting hole 12, and a mounting groove 16 is opened vertically downward;

[0021] The buckle mounting hole 17 is opened on the annular side of the upper body 13 and is connected to the mounting slot 16.

[0022] The vertical extension surface of the anti-rotation mounting hole 15 and the horizontal extension surface of the snap-fit ​​mounting hole 17 are on the same plane.

[0023] Furthermore, the anti-rotation mounting holes 15 are arranged in four sets in a ring at equal intervals;

[0024] Correspondingly, four sets of buckle mounting holes 17 are also provided below the anti-rotation mounting holes 15.

[0025] In this technical solution, since the adjusting body 1 serves to install the inner bolt 2 and the adjusting housing 3, it is necessary to equip the inner bolt 2 and the adjusting housing 3 with corresponding installation structures. The inner bolt 2 is provided with bolt mounting holes 12, and the adjusting housing 3 is provided with anti-rotation mounting holes 15 and snap-fit ​​mounting holes 17 to provide the mounting position for snapping. This not only ensures the stability of the structure after installation, but also simplifies the installation speed between multiple parts, reduces customer assembly time, and lowers customer costs.

[0026] According to a preferred embodiment, the nut portion includes a nut 21 and a lower head step 22, wherein the outer diameter of the lower head step 22 is larger than the outer diameter of the nut 21;

[0027] During installation, the lower step 22 of the head rests against the inner plane of the upper plane 14.

[0028] Furthermore, the nut portion of the inner bolt 2 adopts an internal hexagonal structure.

[0029] In this technical solution, when the nut part adopts a stepped structure, it can form a multi-level contact surface through the matching of structures with different diameters, which can more evenly distribute the axial load generated by the preload of the inner bolt 2 and reduce local stress concentration.

[0030] In addition, the round inner bolt 2 with an internal hexagonal structure is suitable for adjustment in narrow or confined spaces. It can be gradually tightened or loosened by a smaller turning angle, reducing the space required for tool swing. Moreover, it can evenly distribute stress after tightening. Combined with the self-locking characteristics of the thread structure, it can effectively resist loosening caused by vibration or dynamic loads, making it suitable for mechanical parts that require long-term stable adjustment.

[0031] According to the preferred embodiment, adjusting the housing 3 includes:

[0032] The lower body 31 is arranged in a ring;

[0033] The limiting connecting ring 32 is integrally extended from one end of the adjusting housing 3 near the adjusting body 1 to form a limiting connecting ring 32 with a reduced outer diameter. During installation, the limiting connecting ring 32 is inserted into the adjusting body 1.

[0034] Anti-rotation connecting rod 33, which extends vertically along the outer side wall of the limiting connecting ring 32 and the top of the lower body 31 toward the adjusting body 1. After installation, the anti-rotation connecting rod 33 is fitted into the anti-rotation mounting hole 15.

[0035] Anti-rotation buckle 34 is integrally set on the outer side of the anti-rotation connecting rod 33. After installation, the anti-rotation buckle 34 is matched and locked in the buckle mounting hole 17.

[0036] Furthermore, the anti-rotation connecting rod 33 and the anti-rotation buckle 34 are also provided with four sets of anti-rotation mounting holes 15 and buckle mounting holes 17 respectively.

[0037] In this technical solution, a stepped lower body 31 and a limiting connecting ring 32 are provided on the adjusting housing 3 to match the adjusting body 1. Since the outer diameter of the lower body 31 is larger than that of the limiting connecting ring 32, it can ensure that the adjusting body 1 is provided with sufficient support area after installation. Secondly, the limiting connecting ring 32 is fitted inside the adjusting body 1, which can achieve the effect of quick positioning during installation, reduce the installation process, and reduce the assembly time, providing a guarantee for the installation of the anti-rotation connecting rod 33 and the anti-rotation buckle 34.

[0038] The anti-rotation structure used here is achieved by integrating an anti-rotation buckle 34 on the anti-rotation connecting rod 33. After entering upward along the mounting groove 16, the anti-rotation buckle 34 is locked in the buckle mounting hole 17 to achieve a locking effect, which provides a stable installation effect and ensures the stable operation of the vehicle in the future.

[0039] According to the preferred embodiment, a chamfer 35 is provided on the inner top side of the anti-rotation connecting rod 33.

[0040] In this technical solution, the chamfer 35 formed on the anti-rotation connecting rod 33 can serve as a guide structure to help the anti-rotation connecting rod 33 quickly align with the entrance of the mounting slot 16, avoiding jamming or damage to parts due to misalignment, and also reducing the risk of scratching the inner wall of the mounting slot or the operator's hands during assembly.

[0041] According to the preferred embodiment, the top outer side of the anti-rotation buckle 34 is provided with a second chamfer 36.

[0042] Furthermore, the bottom of the anti-rotation buckle 34 is horizontally set.

[0043] In this technical solution, since the anti-rotation buckle 34 is installed on the vertical side of the adjusting body 1 and the buckle mounting hole 17 is set in a horizontal structure, the second chamfer 36 at the top of the anti-rotation buckle 34 forms a sloping guide structure, which can quickly align with the horizontal buckle mounting hole 17. The horizontal surface at the bottom can make it fit with the bottom surface of the buckle mounting hole 17 after installation, so as to obtain a stable and tight connection installation structure.

[0044] According to the preferred embodiment, the length of the anti-rotation connecting rod 33 is greater than the height of the adjusting body 1.

[0045] Furthermore, after installation, the first chamfer 35 of the anti-rotation connecting rod 33 is located on the top outer side of the adjusting body 1.

[0046] In this technical solution, when the adjusting body 1 is connected to the product, interference is avoided when the product contacts the adjusting body 1 during the continuous tightening of the inner bolt 2. The anti-rotation connecting rod 33 is installed and protrudes from the adjusting body 1. In addition, under the action of the locking pressure, the anti-rotation connecting rod 33 forms an abutment structure with the upper sheet metal, preventing the upper sheet metal 4 and the adjusting body 1 from moving due to the rotation of the inner bolt 2, thus achieving a good positioning and locking effect.

[0047] According to the preferred embodiment, the outer diameter of the limiting connecting ring 32 is not greater than the inner diameter of the adjusting body 1.

[0048] Furthermore, the outer diameter of the limiting connecting ring 32 is slightly smaller than the inner diameter of the adjusting body 1, forming a gap between the outer wall of the limiting connecting ring 32 and the inner wall of the adjusting body 1 to accommodate the anti-rotation connecting rod 33.

[0049] In this technical solution, when the outer diameter of the limiting connecting ring 32 is slightly smaller than the inner diameter of the adjusting body 1, it is convenient to quickly align and avoids excessive differences in diameter structure, which would cause long alignment time. This can achieve the pre-positioning of the adjusting housing 3 and shorten the manual alignment time.

[0050] The limiting connecting ring 32 and the adjusting body 1 are fitted together to provide sufficient space for the insertion and installation of the anti-rotation connecting rod 33, and the tight structure will not cause difficulties in installation and alignment.

[0051] According to the preferred embodiment, the anti-loosening structure includes:

[0052] Upper guide groove 5 is formed on the outer periphery of the adjusting body 1, with one end closed at the top and the bottom and outer side both open.

[0053] The lower guide groove 6 is formed on the outer periphery of the adjusting housing 3;

[0054] After installation, the upper guide groove 5 and the lower guide groove 6 are connected and have a spiral structure.

[0055] In this technical solution, multiple upper guide grooves 5 and lower guide grooves 6 are arranged in a ring at equal intervals along the outer periphery of the adjusting body 1 and the adjusting housing 3.

[0056] Furthermore, a fixing hole 8 is provided on the matching lower sheet metal 7. A guide rail 9 is integrally provided on the inner wall of the fixing hole 8, corresponding to the upper guide groove 5 and the lower guide groove 6. During installation, the lower sheet metal 7 slides and locks with the adjusting body 1 and the adjusting housing 3 along with the guide rail 9 to obtain locking force. The spiral rail and the thread of the fixing hole form multi-point contact, generating a mechanical self-locking effect, which provides structural stability for the thrust generated after the inner bolt 2 is tightened.

[0057] According to the preferred embodiment, the screw portion of the inner bolt 2 is threaded onto the upper sheet metal 4, and the adjusting body 1 and the adjusting housing 3 are screwed into the mounting hole 10 of the lower sheet metal 7.

[0058] Furthermore, the gap between the upper sheet metal 4 and the lower sheet metal 7 is adjusted by rotating the inner bolt 2.

[0059] In this technical solution, the body 1, inner bolt 2, adjusting housing 3, upper sheet metal 4 and lower sheet metal 7 are assembled and then infinitely adjusted. After the adjustment is completed, the gap between the upper sheet metal 4 and the lower sheet metal 7 is effectively reduced, which means that the gap between the body and the door handle is adjusted to ensure the stability of the body structure. This can reduce development costs and reduce manual processes.

[0060] This utility model utilizes the structure assembled between the adjusting body 1, the inner bolt 2, and the adjusting housing 3, which is then installed into the corresponding upper sheet metal 4 and lower sheet metal 7 to form a bidirectional force. The pushing force and locking force are used for bidirectional locking and adjustment. After locking, the entire structure is adjusted and locked, thereby achieving stepless adjustment of the gap between the vehicle body and the door handle while ensuring the stability of the vehicle body structure. Furthermore, the simple overall design of the adjusting body 1, the inner bolt 2, and the adjusting housing 3 helps reduce development costs and manual processes. In addition, the structure of the upper sheet metal 4 and the lower sheet metal 7 effectively reduces customer assembly time and costs.

[0079] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0080] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of protection of this utility model may have fewer components, have other components not shown in the drawings, different components, components arranged differently, or components with different connections, etc. Furthermore, two or more components shown in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0082] This utility model proposes an adaptive adjustment component for concealing door handles, used in the process of adjusting the gap between the vehicle body and sheet metal. This utility model does not limit the type of door handle, but the structure of this adaptive adjustment component for concealing door handles is particularly suitable for the needs of concealing door handles in trams.

[0083] In general, the adaptive adjustment component for concealed door handles proposed in this utility model mainly includes an adjustment body 1, an inner bolt 2, and an adjustment housing 3, all arranged coaxially. See also... Figure 1 It shows the arrangement of the adjusting body 1, the inner bolt 2, and the adjusting housing 3.

[0084] To achieve stepless adjustment of the gap between the vehicle body and door handles, this invention addresses the issue that existing technologies mostly rely on manual adjustment. This manual adjustment involves expensive components and depends heavily on operator skill and experience, leading to human error and inconsistencies due to varying skill levels and experience. This compromises the connection stability of each batch of vehicles, posing a safety hazard. Furthermore, manual adjustment requires individual measurement and adjustment, making the process time-consuming. Therefore, this embodiment addresses this problem by assembling the adjusting body 1, the inner bolt 2, and the adjusting housing 3. This assembly is installed into the corresponding upper sheet metal 4 and lower sheet metal 7, creating a bidirectional force. Both thrust and locking forces are used for bidirectional locking and adjustment. Once locked, the entire structure is adjusted and locked, ensuring vehicle body structural stability. The simple overall design of the adjusting body 1, inner bolt 2, and adjusting housing 3 reduces development costs and manual processes. Additionally, the structure of the upper sheet metal 4 and lower sheet metal 7 effectively reduces customer assembly time and costs.

[0085] like Figure 1 and Figure 2 As shown, this embodiment provides a structure of an adjusting body 1, an inner bolt 2, and an adjusting housing 3 arranged coaxially. Considering that the inner bolt 2 can be infinitely adjusted after the adjusting body 1 and the adjusting housing 3 are installed, on the one hand, one axial end of the adjusting body 1 is opened to form an installation end 11 for installing the adjusting housing 3, and the other end is provided with a bolt mounting hole 12 for installing the inner bolt 2. During assembly, the nut part of the inner bolt 2 is located inside the adjusting body 1, and the screw part passes through the bolt mounting hole 12. The top of the adjusting housing 3 is inserted into the adjusting body 1 for installation and locking. The adjusting housing 3 is installed on the end of the adjusting body 1 away from the inner bolt 2. The outer diameters of the adjusting body 1 and the adjusting housing 3 are the same. The locking structure ensures that the adjusting body 1 and the adjusting housing 3 can be locked together.

[0086] On the other hand, the outer periphery of the adjusting body 1 and the adjusting housing 3 is provided with a continuous anti-detachment structure. The anti-detachment structure of the adjusting body 1 and the adjusting housing 3 allows for a tight lock between the adjusting body 1 and the upper and lower sheet metal after installation, preventing loosening. During installation, the screw part passes through the upper sheet metal 4 for locking. After installation, when locking with the customer's sheet metal, the inner bolt 2 of the adjusting circle locks with the upper sheet metal. The adjusting body 1 is subjected to a positive locking force after locking, and the adjusting housing 3 is subjected to a reverse thrust by the reverse thrust structure, so that the positive and negative forces of the adjusting body 1 and the adjusting housing 3 lock together, locking the product with the lower sheet metal, thereby infinitely adjusting the gap between the body and the door handle to ensure the stability of the body structure.

[0087] As described above, the adjusting body 1 provided in this embodiment has bolt mounting holes 12, anti-rotation mounting holes 15, and snap-fit ​​mounting holes 17 on its upper body 13 to accommodate the inner bolt 2 and the adjusting housing 3. This serves to install the inner bolt 2 and the adjusting housing 3. To ensure quick alignment during installation, the upper body 13 is annularly shaped with an opening at the bottom, forming an internal cavity to accommodate the inner bolt 2. The top extends towards the center to form a horizontal upper plane 14. The inner bolt 2 is mounted with bolt mounting holes 12, which are located on the central axis of the upper plane 14. The adjusting housing 3 is equipped with anti-rotation mounting holes 15 and snap-fit ​​mounting holes 17 for... The system provides mounting positions for the anti-rotation mounting holes 15, which are formed around the bolt mounting holes 12 on the upper plane 14 and have vertically downward mounting slots 16. The snap-fit ​​mounting holes 17 are formed on the annular side of the upper body 13 and are connected to the mounting slots 16. The vertical extension surface of the anti-rotation mounting holes 15 and the horizontal extension surface of the snap-fit ​​mounting holes 17 are on the same plane. Four sets of anti-rotation mounting holes 15 are arranged in a ring at equal intervals. Correspondingly, four sets of snap-fit ​​mounting holes 17 are also arranged below the anti-rotation mounting holes 15. This design ensures structural stability after installation, simplifies the installation speed between multiple components, reduces customer assembly time, and lowers customer costs.

[0088] Immediately afterwards, such as Figure 2 and Figure 5 As shown, in this embodiment, the outer diameter of the nut of the inner bolt 2 is larger than the inner diameter of the bolt mounting hole 12. The nut part includes a nut 21 and a lower step 22. The outer diameter of the lower step 22 is larger than the outer diameter of the nut 21. When the structure of the nut part is stepped, it can form a multi-level contact surface by matching structures of different diameters. During installation, the lower step 22 abuts against the inner plane of the upper plane 14, which can distribute the axial load generated by the preload of the inner bolt 2 more evenly and reduce local stress concentration.

[0089] Preferably, since the length of the adjusting body 1 is greater than the height of the nut portion of the inner bolt 2, when it is necessary to adjust the gap between the hidden door handle and the door sheet metal, the adjusting tool needs to be inserted into the adjusting body 1 to operate. Correspondingly, the nut portion of the inner bolt 2 adopts an internal hexagonal structure. The inner bolt 2 with an internal hexagonal structure is suitable for adjustment in narrow or confined spaces. It can be gradually tightened or loosened by a smaller turning angle, reducing the space required for tool swing. Moreover, after tightening, it can evenly distribute stress. Combined with the self-locking characteristics of the thread structure, it can effectively resist loosening caused by vibration or dynamic load, making it suitable for mechanical parts that require long-term stable adjustment.

[0090] It is necessary to explain the overall structure of the adjustment housing 3. The adjustment housing 3 not only needs to match the adjustment body 1, but also needs to match the lower sheet metal 7. For this purpose, a stepped lower body 31 and a limiting connecting ring 32 are set on the adjustment housing 3 to match the adjustment body 1. The lower body 31 is arranged in a ring. The end of the adjustment housing 3 close to the adjustment body 1 extends integrally to form a limiting connecting ring 32 with a reduced outer diameter. During installation, the limiting connecting ring 32 is inserted into the adjustment body 1. Since the outer diameter of the lower body 31 is larger than that of the limiting connecting ring 32, it can ensure the supporting function of the adjustment body 1 after installation and provide sufficient supporting area. Secondly, the limiting connecting ring 32 is fitted into the adjustment body 1, which can achieve the effect of quick positioning during installation, reduce the installation process, and reduce the assembly time, providing a guarantee for the installation of the anti-rotation connecting rod 33 and the anti-rotation buckle 34.

[0091] Furthermore, the outer diameter of the limiting connecting ring 32 is slightly smaller than the inner diameter of the adjusting body 1, forming a gap between the outer wall of the limiting connecting ring 32 and the inner wall of the adjusting body 1 to accommodate the anti-rotation connecting rod 33. When the outer diameter of the limiting connecting ring 32 is slightly smaller than the inner diameter of the adjusting body 1, it facilitates quick alignment and avoids excessive diameter differences that could lead to lengthy alignment times. This allows for the pre-positioning of the adjusting housing 3 and reduces manual alignment time. The gap fit between the limiting connecting ring 32 and the adjusting body 1 provides sufficient space for the insertion and installation of the anti-rotation connecting rod 33, preventing difficulties in installation and alignment due to a tight structure.

[0092] Next, the anti-rotation connecting rod 33 and anti-rotation buckle 34 are installed on the adjusting body 1 inside the adjusting housing 3. The anti-rotation connecting rod 33 and anti-rotation buckle 34 are also provided in four sets corresponding to the anti-rotation mounting hole 15 and buckle mounting hole 17. Specifically, the anti-rotation connecting rod 33 extends vertically along the outer wall of the limiting connecting ring 32 and the top of the lower body 31 toward the adjusting body 1. The anti-rotation buckle 34 is integrally set on the outer surface of the anti-rotation connecting rod 33. After the above structure is installed, the anti-rotation connecting rod 33 is inserted into the anti-rotation mounting hole 15, and the anti-rotation buckle 34 is snapped into the buckle mounting hole 17. After the anti-rotation connecting rod 33 enters upward along the mounting groove 16, the anti-rotation buckle 34 is snapped into the buckle mounting hole 17 to achieve the locking effect, which has the effect of stable installation and provides a guarantee for the stable operation of the vehicle in the future.

[0093] like Figure 9 and Figure 10As shown, the length of the anti-rotation connecting rod 33 is greater than the height of the adjusting body 1. After installation, the first chamfer 35 of the anti-rotation connecting rod 33 is located on the top outer side of the adjusting body 1. When the adjusting body 1 is connected to the product, during the continuous tightening of the inner bolt 2, interference is avoided after the product contacts the adjusting body 1. The anti-rotation connecting rod 33 protrudes from the adjusting body 1 after installation. In addition, under the action of the locking pressure, the anti-rotation connecting rod 33 forms an abutment structure with the upper sheet metal, preventing the upper sheet metal 4 and the adjusting body 1 from moving due to the rotation of the inner bolt 2, thus achieving a good positioning and locking effect.

[0094] Based on this, preferably, both the anti-rotation connecting rod 33 and the anti-rotation buckle 34 are provided with chamfered structures. The top inner side of the anti-rotation connecting rod 33 is provided with a first chamfer 35. The inclined surface formed by the first chamfer 35 on the anti-rotation connecting rod 33 can serve as a guide structure to help the anti-rotation connecting rod 33 quickly align with the entrance of the mounting slot 16, avoiding jamming or damage to parts due to misalignment, and also reducing the risk of scratching the inner wall of the mounting slot or the operator's hands during assembly. The top outer side of the anti-rotation buckle 34 is provided with a second chamfer 36. Since the anti-rotation buckle 34 is installed on the vertical side of the adjusting body 1 and the buckle mounting hole 17 is horizontal, the second chamfer 36 at the top of the anti-rotation buckle 34 forms an inclined guide structure, which can quickly align with the horizontal buckle mounting hole 17. The bottom of the anti-rotation buckle 34 is horizontal. The horizontal surface of the bottom allows it to fit snugly against the bottom surface of the buckle mounting hole 17 after installation, obtaining a stable and tight connection installation structure.

[0095] like Figure 1-10 As shown, the outer periphery of the adjusting body 1 and the adjusting housing 3 is provided with a continuous anti-detachment structure. The upper guide groove 5 is opened on the outer periphery of the adjusting body 1, with one end closed and the bottom and outer side open. The lower guide groove 6 is opened on the outer periphery of the adjusting housing 3. Multiple upper guide grooves 5 and lower guide grooves 6 are arranged in a ring at equal intervals along the outer periphery of the adjusting body 1 and the adjusting housing 3. The upper guide grooves 5 and lower guide grooves 6 are continuously arranged and have a spiral structure.

[0096] After installation, insert the inner bolt 2 into the adjusting body 1, then assemble the adjusting body 1 and the adjusting housing 3, and then install the adjusted part into the lower sheet metal 7. Adjust the gap between the upper sheet metal 4 and the lower sheet metal 7 by rotating the inner bolt 2. Assemble the adjusting body 1 and the adjusting housing 3. The threaded part of the inner bolt 2 is installed on the upper sheet metal 4. After assembly, perform stepless adjustment. After adjustment, the gap between the upper sheet metal 4 and the lower sheet metal 7 is effectively reduced.

[0097] The lower sheet metal 7 is provided with a fixing hole 8. The inner wall of the fixing hole 8 is provided with a guide rail 9 corresponding to the upper guide groove 5 and the lower guide groove 6. During installation, the lower sheet metal 7 slides and locks with the adjusting body 1 and the adjusting housing 3 along with the guide rail 9 to obtain locking force. The spiral rail and the thread of the fixing hole form multi-point contact, generating a mechanical self-locking effect, which provides structural stability for the thrust generated after the inner bolt 2 is tightened.

[0098] When the adjustment component is finally adjusted and locked to the upper sheet metal 4, the adjustment housing 3 is pushed by the anti-detachment structure and the adjustment body 1 is subjected to the positive locking force after locking, so that the positive and negative forces of the adjustment body 1 and the adjustment housing 3 are locked together, locking the fixing hole 8. After locking, the entire structure is adjusted and locked, thereby infinitely adjusting the gap between the body and the door handle to ensure the stability of the body structure.

[0099] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
