[0063] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0064] The present application provides a gap adjustment assembly 10, see Figures 1 to 5 , Figure 1 is an exploded schematic diagram of a gap adjustment assembly provided in an exemplary embodiment of the present disclosure, Figure 2 is an exploded schematic diagram of a gap adjustment assembly and a mounting bracket provided in an exemplary embodiment of the present disclosure, Figure 3 yes Figure 1 An exploded diagram of the gap adjustment assembly and the parts to be adjusted, Figure 4 The gap adjustment assembly 10 includes a fixing portion 1 and a connecting portion 2 .

[0065] The fixing portion 1 is used to be connected to the component 20 to be adjusted, and the fixing portion 1 includes a first locking portion 11 .

[0066] It should be noted that there are many ways to connect the fixing portion 1 to the component to be adjusted 20. For example, in one embodiment, the fixing portion 1 and the component to be adjusted 20 can be bonded. In another embodiment, the fixing portion 1 and the component to be adjusted 20 can be fixed by snap-fit ​​connection. The way in which the fixing portion 1 is connected to the component to be adjusted 20 can be selected as needed, and this application does not limit this. In addition, since the fixing portion 1 and the component to be adjusted 20 are arranged separately, the process difficulty of the component to be adjusted 20 can be reduced.

[0067] Reference Fig.14 , Fig.14 The schematic diagram of the assembly of the gap adjustment assembly with the component to be adjusted and the vehicle body in the exemplary embodiment of the present disclosure is provided. The connecting portion 2 is used to connect with the vehicle body 30 , the connecting portion 2 is slidably connected with the fixing portion 1 , and the connecting portion 2 includes a second locking portion 21 .

[0068] It should be noted that, in one embodiment, the connection portion 2 and the vehicle body 30 can be fixed by bolt connection. In other embodiments, the connection portion 2 and the vehicle body 30 can also be welded, riveted, or bonded by an adhesive. The method of connecting the connection portion 2 to the vehicle body 30 can be selected as needed, and this application does not limit this.

[0069] In addition, the connecting portion 2 is slidably connected to the fixing portion 1 , so that the relative position of the connecting portion 2 and the fixing portion 1 can be freely adjusted along a certain direction and within a certain range, thereby realizing flexible adjustment of the gap between the component 20 to be adjusted and the vehicle body 30 .

[0070] One of the first locking portion 11 and the second locking portion 21 is a rack, and the other of the first locking portion 11 and the second locking portion 21 is an elastic arm. The rack and the elastic arm both extend along the first direction and are arranged opposite to each other. A ratchet 3 is provided on the side of the elastic arm facing the rack. When the connecting portion 2 and the fixing portion 1 slide relative to each other, the ratchet 3 can selectively engage with part of the teeth of the rack.

[0071] It should be noted that when the relative position of the connecting part 2 and the fixed part 1 needs to be adjusted, it is usually necessary to apply external force to one of the connecting part 2 and the fixed part 1 so that the connecting part 2 and the fixed part 1 can slide relative to each other. During the sliding process, the elastic part will be squeezed, causing the elastic arm to deform in the direction away from the rack, resulting in the ratchet 3 being disengaged from the teeth of the rack, making the relative sliding of the connecting part 2 and the fixed part 1 smoother. When the relative position of the connecting part 2 and the fixed part 1 is adjusted, the external force is removed and the elastic arm is reset, so that the ratchet 3 is engaged with part of the teeth of the rack, thereby limiting the relative sliding of the connecting part 2 and the fixed part 1, ensuring the stability after adjustment, avoiding misoperation that causes the connecting part 2 and the fixed part 1 with the adjusted relative position to slide relative to each other again, and ensuring the accuracy of the adjustment.

[0072] In the gap adjustment assembly 10 of the embodiment of the present application, the combination of the elastic arm and the ratchet 3 enables the ratchet 3 on the elastic arm to selectively mesh with some teeth on the rack according to the sliding direction and distance when the connecting part 2 slides relative to the fixed part 1. Since the meshing between the ratchet 3 and the rack is selective, the size of the gap can be adjusted as needed, so that the ratchet 3 can slide through certain tooth grooves and only mesh with specific teeth, thereby achieving a precise fine-tuning function. When the gap is adjusted, the external force is removed. Since the ratchet 3 and the corresponding teeth of the rack are meshed, the relative sliding of the fixed part and the connecting part will be restricted. In this way, it is ensured that the gap will not change after the gap adjustment is completed, thereby ensuring the accuracy of the gap adjustment. In addition, the combination of the elastic arm and the ratchet 3 allows users to easily achieve fine-tuning without using complex tools or performing cumbersome adjustment steps, and the operation is simple.

[0073] Refer to the figure Figure 1 and Figure 5 , Figure 5 It is one of the cross-sectional schematic diagrams after the gap adjustment assembly and the component to be adjusted are assembled in the exemplary embodiment of the present disclosure. In some embodiments, the first locking part 11 is an elastic arm, the fixed part 1 also includes a main body 12 arranged opposite to the elastic arm, the elastic arm includes a connecting end connected to the main body 12 and a free end away from the connecting part 2, and the ratchet 3 is arranged at the free end, so that the distance of the ratchet 3 moving along the direction from the elastic arm to the rack is increased to a certain extent, and the increased moving distance provides more movement space for the ratchet 3, reduces the risk of stagnation during the adjustment process, and improves the smoothness of the adjustment. A side of the main body 12 close to the free end is provided with an avoidance groove 121, and the free end is suitable for moving into the avoidance groove 121, so that the avoidance groove 121 provides an additional movement space for the free end of the elastic arm. When the connecting part 2 and the fixed part 1 slide relative to each other under the action of an external force, the elastic arm is subjected to the force of the teeth of the rack, so that the elastic arm is deformed in the direction away from the rack, so that the free end of the elastic arm moves into the avoidance groove 121, thereby avoiding interference with other components and ensuring the smoothness of the adjustment process. Since the avoidance groove 121 provides additional movement space for the free end, the stress and wear that may be generated at the free end during the adjustment process are reduced. This helps to extend the service life of the gap adjustment assembly 10 and reduce maintenance costs. The design of the avoidance groove 121 cleverly utilizes the space between the main body 12 and the elastic arm, making the entire gap adjustment assembly 10 more compact.

[0074] It should be noted that, refer to Fig.13 In other embodiments, the first locking portion 11 can also be arranged on the connecting portion 2, and the second locking portion 21 can be arranged on the fixing portion 1. Specifically, the setting positions of the first locking portion 11 and the second locking portion 21 can be adjusted as needed, and this application does not limit this.

[0075] Reference Figure 5 and Figure 8 , Figure 8: is a schematic diagram of the structure of the fixing part provided in the exemplary embodiment of the present disclosure. In some embodiments, the elastic arm is tilted toward the rack direction along the direction from the connecting end to the free end. When the elastic arm is tilted toward the rack direction, it will generate a certain preload force on the rack in a natural state. This preload force helps to ensure the stable engagement between the ratchet 3 and the rack, and reduces the disengagement of the ratchet 3 and the rack caused by vibration or external impact without external force. Due to the tilted setting of the elastic arm, the ratchet 3 can be more flexibly engaged with different tooth grooves of the rack during the fine-tuning process, thereby enhancing the fine-tuning ability. In addition, the tilted setting of the elastic arm increases the distance between the free end of the elastic arm and the main body 12, providing more movement space for the ratchet 3, reducing the risk of jamming during the adjustment process, and improving the smoothness of the adjustment. The tilted elastic arm makes the stress change more smoothly during the force-bearing process, thereby reducing the possibility of stress concentration. In addition, during the adjustment process, the externally applied stress can be more evenly distributed on the elastic arm, rather than concentrated at a certain point or a certain area. This not only improves the compressive resistance and durability of the elastic arm, but also reduces life problems such as cracks and breakages caused by stress concentration.

[0076] It should be noted that the cross section of the elastic arm along its length direction may be circular, elliptical or other streamlined cross-sectional shapes, so that the stress concentration phenomenon generated at the cross-sectional mutation point can be reduced. Of course, in other embodiments, the cross section of the elastic arm along its length direction may also be square or triangular, etc., and this application does not limit this.

[0077] There are many ways to achieve the sliding connection between the connecting part 2 and the fixing part 1. For example, Figure 1 , Figure 6 and Figure 7 , Figure 6 is a schematic structural diagram of a connecting portion provided in an exemplary embodiment of the present disclosure, Figure 7 yes Figure 6A schematic diagram of the structure of the connecting part at another angle shown. In some embodiments, one of the fixing part 1 and the connecting part 2 is provided with a slide groove 41, and the slide groove 41 is extended along the first direction. The other of the fixing part 1 and the connecting part 2 is provided with a slide 42 that slides with the slide groove 41. In this way, the cooperation between the slide groove 41 and the slide 42 allows the connecting part 2 and the fixing part 1 to slide relative to each other within a certain range. This design allows the relative position between the connecting part 2 and the fixing part 1 to be adjusted as needed, thereby improving the flexibility of the connection. The slide groove 41 provides a clear guide path for the slide 42, ensuring the stability and accuracy of the slide 42 during the sliding process, and avoiding deviation or shaking. Sliding cooperation usually has less friction resistance, thereby reducing the wear between the connecting part 2 and the fixing part 1 and extending the service life. The cooperation between the slide groove 41 and the slide 42 makes the installation and debugging process more convenient, without complicated positioning and fixing steps, and improves work efficiency. When it is necessary to replace or adjust parts, this design also facilitates the disassembly and reassembly of the connecting part 2 and the fixing part 1, and improves the reusability of the connecting part 2 and the fixing part 1. The design of the slide groove 41 and the slide platform 42 makes the overall structure of the gap adjustment assembly 10 more compact and reasonable.

[0078] There are many ways to achieve sliding connection between the connecting part 2 and the fixed part 1. In another embodiment, the connecting part 2 and the fixed part 1 can also be slidably connected by a guide rail and a slider. The guide rail is fixed on the fixed part 1, and the slider is installed on the connecting part 2. The relative movement of the connecting part 2 and the fixed part 1 is achieved by rolling or sliding the slider on the guide rail. In another embodiment, the connecting part 2 and the fixed part 1 can also be slidably connected by a slide rail and a slide groove 41. In other embodiments, the connecting part 2 and the fixed part 1 can also be slidably connected by a sliding rod provided in one of the connecting part 2 and the fixed part 1 and another through hole provided in the connecting part 2 and the fixed part 1. Specifically, the method for achieving sliding connection between the connecting part 2 and the fixed part 1 can be selected as needed, and this application does not limit this.

[0079] Reference Figure 5 In some embodiments, the slide 42 is connected to one of the rack and the elastic arm, and the inner side of the side wall of the slide groove 41 is connected to the other of the rack and the elastic arm. In this way, the overall structure of the gap adjustment assembly 10 is more compact, which is conducive to saving space.

[0080] It should be noted that there are many ways to connect the slide 42 to one of the rack and the elastic arm. For example, in one embodiment, one of the rack and the elastic arm can be integrally formed with the slide 42. In another embodiment, one of the rack and the elastic arm can be welded and fixed to the slide 42. In other embodiments, one of the rack and the elastic arm can be threadedly connected to the slide 42 through the screw 40 or fixed by adhesive. Specifically, the way the slide 42 is connected to one of the rack and the elastic arm can be selected as needed, and the present application does not limit this.

[0081] Similarly, there are many ways to connect the inner side of the side wall of the chute 41 with the other of the rack and the elastic arm. For example, in one embodiment, the other of the rack and the elastic arm can be integrally formed with the inner side of the side wall of the chute 41. In another embodiment, the other of the rack and the elastic arm can be welded and fixed to the inner side of the side wall of the chute 41. In other embodiments, the other of the rack and the elastic arm can be threadedly connected to the inner side of the side wall of the chute 41 through the screw connector 40 or fixed by adhesive. Specifically, the way in which the inner side of the side wall of the chute 41 is connected with the other of the rack and the elastic arm can be selected as needed, and this application is not limited thereto.

[0082] Reference Figure 5 In some embodiments, the elastic arm, the rack and the ratchet 3 together constitute a locking unit, and two locking units are provided, and the two locking units are arranged oppositely. In this way, by providing two oppositely arranged locking units, a double locking effect can be achieved. When one locking unit may fail for some reason during the locking process, the other locking unit can still maintain the locking state, thereby improving the stability and reliability of the entire gap adjustment assembly 10. The two oppositely arranged locking units can ensure that the force is more uniform during the locking process. This helps to reduce the stress concentration and deformation caused by uneven force, and further improves the locking effect and the stability of the gap adjustment assembly 10. The cooperation between the ratchet 3 and the rack can achieve high-precision gap adjustment. By providing two locking units, the adjustment accuracy can be further improved. In addition, after the gap adjustment is completed, the relative movement of the connecting part 2 and the fixing part 1 can be stably limited, so that the connecting part 2 and the fixing part 1 can be maintained at a predetermined position. When a large load is applied to the fixing part 1 or the connecting part 2, the two locking units can share these loads together to avoid damage to a single locking unit due to excessive force.

[0083] Reference Figure 6 and Figure 7In some embodiments, the connecting portion 2 is provided with a slide groove 41, and the slide groove 41 includes a first groove section 411 and a second groove section 412 which are sequentially connected and arranged along the direction from the groove bottom to the groove mouth. The cross-sectional area of ​​the first groove section 411 along the direction from the groove bottom to the groove mouth is greater than the cross-sectional area of ​​the second groove section 412. The first groove section 411 has a first abutting surface 4111 arranged toward the groove bottom. The fixing portion 1 is provided with a slide 42, and the slide 42 is at least partially slidably installed in the first groove section 411. The slide 42 has a second abutting surface 421 arranged away from the groove bottom, and the second abutting surface 421 is suitable for abutting with the first abutting surface 4111. In this way, the larger cross-sectional area of ​​the first groove section 411 provides a stable sliding space for the slide 42, which helps the slide 42 to slide smoothly at least partially in the slide groove 41. The setting of the first abutting surface 4111 and the second abutting surface 421 prevents the slide 42 from moving in the direction away from the bottom of the groove, causing the slide 42 to detach from the slide groove 41, thereby ensuring the stable fit between the slide 42 and the slide groove 41 and improving the stability of the sliding connection between the fixing part 1 and the connecting part 2.

[0084] It should be noted that, in some embodiments, the slide 42 may be partially slidably installed in the first slot section 411. In other embodiments, the slide 42 may be fully slidably installed in the first slot section 411. Specifically, this application does not limit this. Fig.12 , Fig.12 This is the second structural schematic diagram of the assembly of the gap adjustment assembly and the component to be adjusted in the exemplary embodiment of the present disclosure. In this embodiment, the fixing part 1 is provided with a slide groove 41, and the connecting part 2 is provided with a slide platform 42.

[0085] Refer again Figure 1 , Figure 6 and Figure 7In one embodiment, the vehicle body 30 includes a mounting frame 301, and the connecting portion 2 also includes a base 22 and two connecting plates 23. The base 22 is used to connect with the mounting frame 301, and the two connecting plates 23 are arranged oppositely and at intervals. One end of the two connecting plates 23 is bent in a direction close to each other, so that each connecting plate 23 includes a connecting section 231 and a bending section 232 connected in sequence, and the free ends of the two connecting sections 231 are connected to the base 22, and the two bending sections 232 are arranged at intervals and opposite to the base 22, wherein the two bending sections 232 are arranged to form a second slot section 412, and the two connecting sections 231 and the base 22 are arranged to form a first slot section 411 together. In this way, the formation of the first slot section 411 and the second slot section 412 does not require additional components, but is directly formed by the bending of the connecting plate 23 and the base 22, which optimizes the spatial layout and reduces the difficulty and cost of processing. In addition, it makes it easier to clean and maintain the slide 41. The design of directly forming the first slot section 411 and the second slot section 412 by the bending of the connecting plate 23 and the base 22 reduces the connection points and potential failure points, and the structure of the entire connecting part 2 is more durable, reducing the failure caused by loose or damaged parts.

[0086] Reference Figure 4 , Figure 6 and Figure 7In one embodiment, the component 20 to be adjusted is provided with a guide boss 201, which is extended along the first direction, and the fixing part 1 is used to be connected to the guide boss 201, and the guide boss 201 is slidably installed in the second groove section 412. In this way, the connection design of the guide boss 201 and the fixing part 1 realizes the connection between the component 20 to be adjusted and the gap adjustment assembly 10, which is convenient for adjusting the gap between the component 20 to be adjusted and the vehicle body 30. In addition, the sliding installation of the guide boss 201 in the second groove section 412 enables the component 20 to be adjusted to slide along the first direction during the position adjustment process, which limits the degree of freedom of the component 20 to be adjusted in other directions and avoids the occurrence of displacement or misalignment during the position adjustment process. The guide boss 201 extends along the first direction and is slidably installed in the groove section, which ensures the smooth sliding of the component 20 to be adjusted during the position adjustment process and reduces the resistance and friction during the position adjustment. The slide 42 is slidably mounted in the first groove section 411. In this way, the sliding installation of the slide 42 in the first groove section 411 ensures its stability during the sliding process and reduces the vibration and noise during sliding. The guide boss 201 and the slide 42 are slidably mounted in the second groove section 412 and the first groove section 411 respectively. This design limits the freedom of the component to be adjusted 20 and the fixing part 1 in multiple directions, making the component to be adjusted 20 and the fixing part 1 more stable during the movement, reducing the possibility of shaking and deviation. The cooperation between the guide boss 201 and the second groove section 412, and the cooperation between the slide 42 and the first groove section 411, enhance the connection strength between the component to be adjusted 20, the fixing part 1 and the connecting part 2, and improve the stability of the overall structure of the gap adjustment assembly 10.

[0087] Reference Figure 5 , Figure 8 and Fig.10 , Fig.10 : is a cross-sectional schematic diagram of the connection part and the fixing part after assembly provided in the exemplary embodiment of the present disclosure. In some embodiments, a positioning structure is also provided between the slide 42 and the guide boss 201, and the positioning structure includes a positioning protrusion 51 and a positioning hole 52 adapted to the positioning protrusion 51. One of the positioning protrusion 51 and the positioning hole 52 is provided on the slide 42, and the other is provided on the guide boss 201. In this way, the matching design of the positioning protrusion 51 and the positioning hole 52 ensures the accurate alignment of the slide 42 and the guide boss 201 in relative position, avoiding errors caused by position deviation. The operator can quickly find the correct position of the slide 42 and the guide boss 201 through the positioning structure, which simplifies the adjustment process and improves the installation efficiency.

[0088] It should be noted that there are many types of positioning structures. For example, in one embodiment, the slide 42 and the guide platform can also be provided with positioning holes, and the positioning structure can also include a positioning pin. By adjusting the position, the positioning hole of the slide 42 and the positioning hole of the guide platform are relatively positioned, and then the positioning pin is inserted into the two positioning holes to achieve accurate installation of the slide 42 and the guide platform. In other embodiments, the positioning structure can also include a magnetic attraction portion and a magnetic attraction matching portion that magnetically matches the magnetic attraction portion. One of the magnetic attraction portion and the magnetic attraction matching portion is provided on the slide 42, and the other can be provided on the guide boss 201. Specifically, the specific selection of the type of positioning structure can be made as needed, and this application does not limit this.

[0089] Reference Figure 5 , Figure 8 and Fig.10 In some embodiments, two positioning structures are provided, and the connecting line of the two positioning structures is arranged at an angle with the extension line of the first direction. By providing two positioning structures, multi-point positioning of the slide 42 and the guide boss 201 is achieved. Compared with single-point positioning, multi-point positioning can more effectively limit the freedom of movement between the slide 42 and the guide boss 201, and improve the accuracy and stability of positioning. The connecting line of the two positioning structures is arranged at an angle with the extension line of the first direction. This layout method helps to disperse the force and reduce the deformation or displacement caused by excessive force in a single direction, thereby further enhancing the stability of the connection between the slide 42 and the guide boss 201. The two positioning structures arranged at an angle help to disperse the force of the slide 42 and the guide boss 201 during the movement process, reduce the wear and damage caused by excessive local force, and thus extend the service life of the slide 42 and the guide boss 201.

[0090] Reference Figure 7 and Fig. 9In some embodiments, a limiting structure is further provided between the fixing portion 1 and the connecting portion 2. The limiting structure is in the slide groove 41 and includes a limiting groove 61 extending in the first direction and a limiting protrusion 62 matched with the limiting groove 61. The limiting protrusion 62 is slidably installed in the limiting groove 61. One of the limiting groove 61 and the limiting protrusion 62 is provided in the fixing portion 1, and the other is provided in the connecting portion 2. In this way, the cooperation between the limiting groove 61 and the limiting protrusion 62 plays a guiding role, so that the connecting portion 2 can move smoothly along the direction of the limiting groove 61 during the adjustment process, thereby avoiding deviation in the adjustment direction. During the adjustment process, the operator only needs to push the connecting portion 2 in the direction of the limiting groove 61 to achieve precise adjustment, without the need for complex alignment operations, thereby simplifying the adjustment steps. In addition, the cooperation of the limiting groove 61 and the limiting protrusion 62 limits the relative movement range of the fixing part 1 and the connecting part 2 along the first direction, and avoids the relative movement range of the fixing part 1 and the connecting part 2 along the first direction being too large, causing the slide 42 to slide out of the slide groove 41. The cooperation of the limiting groove 61 and the limiting protrusion 62 accurately limits the relative movement range of the fixing part 1 and the connecting part 2 along the first direction. This enables the operator to control the travel more accurately during the gap adjustment process, and improves the adjustment accuracy.

[0091] It should be noted that the matching mode of the limiting groove 61 and the limiting protrusion 62 can be adjusted and optimized according to specific working conditions and design requirements. For example, by changing the shape, size or position of the limiting groove 61, different relative movement ranges and adjustment accuracy requirements can be met.

[0092] In some embodiments, the limiting protrusion 62 is provided on the fixing portion 1, and the surface of the limiting protrusion 62 is at least partially provided as an arc surface, and the arc surface is used for slidingly contacting with the connecting portion 2, so that the design of the arc surface enables the limiting protrusion 62 to form a smooth transition in the process of sliding into the limiting groove 61. This design reduces the friction and collision between the limiting protrusion 62 and the edge of the limiting groove 61, thereby reducing the sliding resistance. Due to the reduction of the sliding resistance, the efficiency of the limiting protrusion 62 sliding into the limiting groove 61 will also be improved accordingly, which helps to improve the assembly efficiency of the gap adjustment component 10. The wear of the limiting protrusion 62 and the limiting groove 61 during the relative sliding process will also be reduced accordingly. This not only prolongs the service life of the limiting protrusion 62 and the limiting groove 61, but also improves the overall performance of the gap adjustment component 10. The design of the arc surface has a certain guiding effect. When the limiting protrusion 62 slides on the connecting portion 2 and approaches the limiting groove 61, the arc surface can guide the limiting protrusion 62 to enter the limiting groove 61 more accurately, thereby improving the alignment accuracy. Due to the guiding effect of the arc surface, the limiting protrusion 62 is less likely to deviate or get stuck during the process of sliding into the limiting groove 61. This ensures the stability and reliability of the fixing portion 1 and the connecting portion 2 during the relative movement.

[0093] Reference Figure 1 , Figure 3 and Fig.11 , Fig.11 This is one of the structural schematic diagrams of the gap adjustment assembly and the component to be adjusted provided in the exemplary embodiment of the present disclosure. In some embodiments, the mounting frame 301 is detachably connected to the base 22, so that the installer can remove the gap adjustment assembly 10 from the vehicle body as needed to facilitate maintenance of the gap adjustment assembly 10.

[0094] It should be noted that there are several ways to achieve the detachable connection between the mounting frame 301 and the base 22, see Figure 1 , Figure 3 and Figure 6 In one embodiment, the base 22 and the mounting frame 301 are connected by a snap-fit ​​structure, and the snap-fit ​​structure includes a matching snap-fit ​​protrusion 71 and a snap-fit ​​groove 72, one of the snap-fit ​​protrusion 71 and the snap-fit ​​groove 72 is provided on the base 22, and the other is provided on the mounting frame 301, and the mounting frame 301 can be detachably connected to the base 22 by the matching installation of the snap-fit ​​protrusion 71 and the snap-fit ​​groove 72. In other embodiments, the base 22 and the mounting frame 301 can also be threadedly connected by a threaded structure. Specifically, the method for realizing the detachable connection between the mounting frame 301 and the base 22 can be selected as needed, and the present application does not limit this.

[0095] Reference Figure 1 In some embodiments, the card slot 72 is extended along the first direction, so that the card protrusion 71 installed in the card slot 72 can move a certain distance along the first direction to absorb the assembly error of the mounting frame 301. In this way, the installation operation between the base 22 and the mounting frame 301 is simple and the installation efficiency is improved.

[0096] Specifically, the installation process of the gap adjustment assembly 10 is described below:

[0097] The positioning hole 52 on the main body 12 is positioned to the component to be adjusted 20 through the positioning protrusion 51 on the component to be adjusted 20, and the main body 12 is bonded to the component to be adjusted 20 by using glue; the slide 42 is inserted into the slide groove 41, and the limiting protrusion 62 slides into the limiting groove 61 at the same time, which plays a limiting role in preventing the connecting part 2 from escaping from the fixing part 1; the locking protrusion 71 of the connecting part 2 is inserted into the locking groove 72 on the mounting frame 301 of the vehicle body 30, so that the positioning and installation of the component to be adjusted 20 is achieved.

[0098] According to a second aspect of the present disclosure, a vehicle is provided, Fig.14The vehicle comprises a vehicle body 30, a component to be adjusted 20 and the above-mentioned gap adjustment assembly 10. The gap adjustment assembly 10 connects the vehicle body 30 and the component to be adjusted 20. Since the vehicle has all the beneficial effects of the above-mentioned gap adjustment assembly 10, the present disclosure will not repeat them here.

[0099] It should be noted that the gap adjustment assembly 10 can be produced in a standardized module and can be used for different components 20 to be adjusted, thereby improving the versatility of the gap adjustment assembly 10.

[0100] Reference Figure 1 , Figure 3 and Fig.14 , Fig.14 It is a schematic diagram of assembling a gap adjustment assembly with a component to be adjusted and a vehicle body in an exemplary embodiment of the present disclosure. In some embodiments, the component 20 to be adjusted is provided with a first mounting hole 202, the fixing portion 1 is provided with a second mounting hole 13, and the connecting portion 2 is provided with a long hole 24, and the long hole 24 is extended along the first direction. The vehicle also includes a threaded component 40, including a screw 401 and a nut 402, the screw 401 is passed through the first mounting hole 202, the second mounting hole 13 and the long hole 24 and is threadedly connected to the nut 402. Since the connecting portion 2 is provided with the long hole 24 extending along the first direction, when the gap adjustment between the component 20 to be adjusted and the vehicle body 30 is completed, the screw 401 is passed through the first mounting hole 202, the second mounting hole 13 and the long hole 24, and is threadedly connected to the nut 402, so as to form a stable connection structure, thereby ensuring that the position between the component 20 to be adjusted and the vehicle body 30 is fixed after the gap adjustment is completed, avoiding the change of the adjusted gap between the component 20 to be adjusted and the vehicle body 30 due to misoperation, and improving the accuracy of adjustment. The threaded connection between the nut 402 and the screw rod 401 has good self-locking properties, which can effectively prevent the connection between the component 20 to be adjusted and the vehicle body 30 from loosening due to vehicle vibration, thereby improving safety. The design of the screw connector 40 makes the installation process of the component 20 to be adjusted relatively simple, and only requires the screw rod 401 to be inserted into each installation hole and fastened with the nut 402. When the component 20 to be adjusted needs to be disassembled or replaced, it can be easily removed by loosening the nut 402, which is convenient for maintenance and replacement.

[0101] The vehicle may be a fuel vehicle, a plug-in hybrid vehicle, a new energy vehicle, etc., and the present disclosure does not make any specific limitation on this.

[0102] In addition, there are many types of the component 20 to be adjusted. For example, in one embodiment, the component 20 to be adjusted may include a fender. The fender is made of plastic. In other embodiments, the component 20 to be adjusted may also include a rear fender or a front bumper. Specifically, the type of the component 20 to be adjusted may be selected as needed, and this application does not limit this.

[0103] The present disclosure exemplarily describes that a vehicle adjusts the gap between a component to be adjusted 20 and a vehicle body 30 by using a gap adjustment assembly 10. The following takes the component to be adjusted 20 as a fender as an example to describe the working process of the gap adjustment assembly 10:

[0104] The slide 42 provided on the fixing part 1 and the guide boss 201 provided on the part to be adjusted 20 are positioned by two positioning structures, so that the second mounting hole 13 corresponds to the first mounting hole 202, and the positioned slide 42 and the guide boss 201 are connected and fixed to form a whole. The slide 42 is slid into the first groove section 411, and the corresponding guide boss 201 is slid into the second groove section 412, so that the fixing part 1 and the connecting part 2 can only slide relative to each other along the first direction. During the relative sliding process of the fixing part 1 and the connecting part 2, the limiting protrusion 62 will slide into the limiting groove 61 to prevent the fixing part 1 and the connecting part 2 from sliding too far in the first direction, causing the slide 42 to be separated from the first groove section 411. The base 22 and the mounting frame 301 are fixed by the buckle structure, so that the base 22 and the mounting frame 301 are fixed in the first direction. Due to the arrangement of the elastic arm, the ratchet 3 and the rack, when the fender is pulled away from the vehicle body 30 to pull the fixing part 1, the elastic arm will be deformed away from the rack, and the ratchet 3 can slide relative to the rack, so that the fixing part 1 can slide smoothly relative to the connecting part 2 until the fixing part 1 cannot slide relative to the connecting part 2. At this time, the fender moves away from the vehicle body 30 by a first distance, so as to avoid interference between the front bonnet assembly and the fender when it is lowered. Place the gap standard block against the surface of the fender near the gap adjustment component 10, then lower the hood assembly to the required position, and push the fender toward the vehicle body 30, the elastic arm will deform in the direction away from the rack, the ratchet 3 can slide relative to the rack, so that the fixed part 1 slides smoothly relative to the connecting part 2 until the gap standard block contacts the hood assembly. Due to the elastic pressure of the elastic arm of the fixed part 1 and the selective engagement of the ratchet 3 with the teeth of the rack of the connecting part 2, the elastic arm will return to its original position in the absence of external force, so that the ratchet 3 is engaged with the teeth corresponding to the rack, and the relative position of the fender and the hood assembly will not change after the gap adjustment is completed. Ensure that the gap between the fender and the hood assembly meets the standard. Then open the front hood assembly, insert the screw 401 through the first mounting hole 202, the second mounting hole 13 and the long hole 24 and threadedly connect it with the nut 402 to fix the position of the fender, the connecting part 2 and the fixing part 1, remove the gap ensuring block, and complete the assembly of the fender.

[0105] It should be noted that the first distance is H, where 4.5 mm ≤ H ≤ 5 mm. Thus, since the theoretical distance between the fender and the surrounding matching parts is only 3.5 mm to 4 mm, by limiting the first distance to between 4.5 mm and 5 mm, the fender can be prevented from interfering with other matching parts, while at the same time preventing the fender from deforming due to a large movement distance and causing appearance defects. Of course, for other components 20 to be adjusted, the first distance can be set as needed, and this application does not limit this.
