Description

Technical Field

[0001] The utility model relates to the technical field of vehicle equipment, in particular to a positioning structure and a vehicle. Background Art

[0002] In the related art, when at least two parts need to be assembled, a positioning structure is usually used to assist in positioning in order to ensure that the assembly position can be found quickly and accurately. However, after the two parts are assembled, their positions are immediately fixed and cannot be moved. The error between the two parts may exceed the requirements due to manufacturing errors, processing errors, assembly errors, etc. If the position of the positioning structure needs to be modified to meet the required error between the two parts, the related art involves modifying the production mold to adjust the position of the positioning structure on the component, but this process is time-consuming and costly.

[0003] When at least two components are being assembled on a production line, if the matching errors between the components exceed requirements, structural changes cannot be quickly made, and the relative positions of products cannot be easily adjusted in batches. This defect can easily lead to excessive clearance and face differences between parts, resulting in serious quality problems. When encountering this problem, the factory must stop the line for countermeasures and rectification, which affects the factory's assembly plan and project development cycle. Therefore, it needs to be solved. Utility Model Content

[0048] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0049] Reference below Figures 1-16 A positioning structure 100 according to an embodiment of the present invention is described.

[0050] Reference Figure 2-Figure 4 According to the positioning structure 100 of the embodiment of the first aspect of the present invention, it includes a first positioning member 1 and a second positioning member 2. The first positioning member 1 is used to be arranged on the first component, the second positioning member 2 is used to be arranged on the second component and the second positioning member 2 is detachably connected to the second component. The second positioning member 2 is detachably connected to the first positioning member 1 to connect the first component and the second component. The connection between the first positioning member 1 and the second positioning member 2 can assist in positioning the second component on the first component, so that the assembly position of the second component on the first component is accurate.

[0051] The second positioning member 2 has multiple different assembly states relative to the first positioning member 1, and in different assembly states, the position of the second positioning member 2 relative to the first positioning member 1 is different. Since the second positioning member 2 is detachably connected to the first positioning member 1 and the second positioning member 2 has multiple different assembly states relative to the first positioning member 1, and in different assembly states, the position of the second positioning member 2 relative to the first positioning member 1 can be changed, the flexibility of the assembly process of the first component and the second component can be increased, so that even if there is an assembly error between the first component and the second component, the assembly state of the second positioning member 2 can be adjusted to adapt to different assembly requirements or compensate for the manufacturing error between the first component and the second component.

[0052] For example, if there is a certain assembly error between the first component and the second component, the assembly error between the first component and the second component can be compensated by adjusting the position of the second positioning member 2 relative to the first positioning member 1 without changing the first component or the second component, thereby effectively reducing the assembly gap between the first component and the second component and improving the assembly accuracy. In addition, since the second positioning member 2 is detachably connected to the second component, it is more convenient to adjust or replace the second positioning member 2 when it is needed. There is no need to modify the first component or the second component itself, or modify the production mold to adjust the position of the second positioning member 2 on the second component or the position of the first positioning member 1 on the first component, which reduces the time and cost consumption caused by adjusting the production mold, thereby improving the overall assembly efficiency of the first component and the second component.

[0053] In the description of the present invention, “plurality” means two or more.

[0054] Alternatively, the first component can be made of resin materials such as PP, ABS, PC+ABS, PC, PA, or PA+GF, and the second component can be made of resin materials such as PP, ABS, PC+ABS, PC, PA, or PA+GF. To avoid abnormal noise when the first and second components are mated, avoid selecting material combinations that are prone to abnormal noise. For example, if both the first and second components are made of PC+ABS, friction between the materials is likely to produce abnormal noise. Of course, the first and second components can also be made of metal.

[0055] According to the positioning structure 100 of the embodiment of the present invention, the first positioning member 1 is detachably connected to the second positioning member 2, and the second positioning member 2 is detachably connected to the second component. After the second component is assembled with the first component, if the error between the second component and the first component exceeds the requirement, the second positioning member 2 can be removed from the second component, and the position of the second positioning member 2 relative to the first positioning member 1 can be adjusted to change the assembly state of the second positioning member 2, and then the second positioning member 2 can be installed to the second component. In this way, the position of the second component relative to the first component can be adjusted so that the error between the second component and the first component meets the requirement. There is no need to modify the production mold to change the structure. It is only necessary to remove the second positioning member 2 from the second component and adjust the position of the second positioning member 2 relative to the first positioning member 1. This makes the operation of adjusting the position of the second component relative to the first component simpler, shortens the time required for position adjustment, and reduces costs.

[0056] Reference Figure 9 、 Figure 11 and Figure 12According to some embodiments of the present invention, the second positioning member 2 includes a positioning column 21, and a positioning mounting hole 200 for cooperating with the positioning column 21 is provided on the second component. The central axis of the positioning column 21 cooperating with the positioning mounting hole 200 is the first central axis a. In different assembly states, the position of the first central axis a relative to the first positioning member 1 is different. The positioning mounting hole 200 can facilitate the passage of the positioning column 21, making the assembly between the second component and the second positioning member 2 more convenient, and can make the overall structure of the second component and the second positioning member 2 compact. Since the position of the first central axis a relative to the first positioning member 1 is different in different assembly states, the position of the second positioning member 2 relative to the first positioning member 1 can be adjusted by adjusting the position of the first central axis a relative to the first positioning member 1, and then the relative position between the second component and the first component can be adjusted.

[0057] Reference Figure 9 、 Figure 11 and Figure 12 According to some embodiments of the present invention, a through hole 11 is formed on the first positioning member 1, and a positioning column 21 that cooperates with the positioning mounting hole 200 is provided through the through hole 11. The central axis of the through hole 11 is the second central axis b. In different assembly states, the position of the first central axis a relative to the second central axis b is different. The through hole 11 can facilitate the passage of the positioning column 21, making the assembly of the second positioning member 2 and the first positioning member 1 more convenient, and can make the overall structure of the second positioning member 2 and the first positioning member 1 compact. Since the position of the first central axis a relative to the second central axis b is different in different assembly states, the position of the second positioning member 2 relative to the first positioning member 1 can be adjusted by adjusting the position of the first central axis a relative to the second central axis b.

[0058] Reference Figure 9 、 Figure 11 and Figure 12 According to some embodiments of the present invention, the plurality of different assembly states include a first assembly state and a second assembly state. In the first assembly state, the first central axis a and the second central axis b are collinear; in the second assembly state, the first central axis a is aligned with the second central axis b along a first direction (e.g., referring to Figure 1 The first direction is perpendicular to the first central axis a).

[0059] When the second positioning member 2 is in the first assembly state, the positioning column 21 of the second positioning member 2 passes through the hole 11 and is installed in the first positioning member 1, and the positioning column 21 is installed in the positioning installation hole 200 to enable the second positioning member 2 to be installed on the second component. At this time, the first center axis a and the second center axis b are collinear. The second positioning member 2 cooperates with the first positioning member 1 to assist in accurately assembling the first component on the second component.

[0060] When the second positioning member 2 is in the second assembly state, the positioning column 21 of the second positioning member 2 passes through the hole 11 and is installed in the first positioning member 1, and the positioning column 21 is installed in the positioning installation hole 200 to enable the second positioning member 2 to be installed on the second component. At this time, the first center axis a is offset relative to the second center axis b along the first direction. For example, the distance that the first center axis a is offset relative to the second center axis b along the first direction is N2. At this time, the first component can be offset relative to the second component along the first direction by -N2 to achieve adjustment of the relative position between the first component and the second component along the first direction.

[0061] Reference Figure 9 、 Figure 11 and Figure 12 According to some embodiments of the present invention, the second positioning member 2 includes a mounting block 23 and two positioning posts 21. The two positioning posts 21 are connected to the mounting block 23 along the third direction (for example, refer to Figure 9 On opposite sides of the mounting plate (direction e3 in the figure), the first central axis a extends along the third direction. The central axes of the two positioning posts 21 are spaced apart and arranged along the first direction. In the first assembled state, one positioning post 21 passes through the through hole 11 and engages with the positioning and mounting hole 200. In the second assembled state, the other positioning post 21 passes through the through hole 11 and engages with the positioning and mounting hole 200.

[0062] Because the central axes of the two positioning posts 21 are spaced apart, there is a certain distance between the central axes of the two positioning posts 21. For example, the central axes of the two positioning posts 21 differ by N2 along the first direction. By having the two positioning posts 21 respectively pass through the through hole 11 and cooperate with the positioning and mounting hole 200, the first central axis a can be offset by N2 relative to the second central axis b along the first direction. For example, when the second positioning member 2 is adjusted from the first assembly state to the second assembly state, the two positioning posts 21 can be flipped 180° along the third direction to allow the other positioning post 21 to pass through the through hole 11 and cooperate with the positioning and mounting hole 200.

[0063] By adjusting the matching relationship between the two positioning columns 21 and the positioning mounting holes 200 to adjust the position of the second positioning member 2 relative to the first positioning member 1 along the first direction, the distance of the position adjustment of the second positioning member 2 relative to the first positioning member 1 along the first direction can be more accurately controlled.

[0064] In this embodiment, the positioning post 21 is cross-shaped. Optionally, the positioning post 21 may also be cylindrical, conical, etc.

[0065] Reference Figure 8 、 Figure 10 、 Figure 13 and Figure 14According to some embodiments of the present invention, the plurality of different assembly states include a third assembly state. In the third assembly state, the first central axis a is relative to the second central axis b along the second direction (for example, referring to Figure 1 The second direction is perpendicular to the first central axis a and intersects the first direction. When the second positioning member 2 is in the third assembly state, one of the positioning posts 21 of the second positioning member 2 passes through the hole 11 and is installed in the positioning installation hole 200 to enable the second positioning member 2 to be installed on the second component. At this time, the first central axis a is offset relative to the second central axis b in the second direction. For example, the first central axis a is offset relative to the second central axis b in the second direction by a distance N1. At this time, the first component can be offset relative to the second component in the second direction by -N1, thereby adjusting the relative position between the first and second components along the second direction.

[0066] Reference Figure 8 、 Figure 10 and Figure 13 According to some embodiments of the present invention, the first positioning member 1 is provided with two first positioning surfaces 12 spaced apart along the circumference of the first positioning member 1, and the outer peripheral side of the second positioning member 2 is provided with two second positioning surfaces 22 spaced apart along the circumference of the second positioning member 2. The first positioning surfaces 12 and the second positioning surfaces 22 contact each other in a direction perpendicular to the first central axis a to limit the position of the second positioning member 2. The first positioning surfaces 12 limit the second positioning surfaces 22, thereby ensuring the stability of the second positioning member 2 after assembly with the first positioning member 1, thereby reducing or preventing the position of the second positioning member 2 relative to the first positioning member 1 from changing due to external impact or vibration.

[0067] The two second positioning surfaces 22 are at different distances from the central axis of the second positioning member 2 . The position of the second positioning member 2 relative to the first positioning member 1 along the second direction can be adjusted by adjusting the positional relationship of the two second positioning surfaces 22 .

[0068] Reference Figure 8 、 Figure 10 and Figure 13 According to some embodiments of the present invention, the two second positioning surfaces 22 are located on opposite sides of the second positioning member 2 along the second direction. Since the two first positioning surfaces 12 are located on opposite sides of the first positioning member 1 along the second direction, the position of the second positioning member 2 relative to the first positioning member 1 along the second direction can be adjusted by adjusting the matching relationship between the two second positioning surfaces 22 and the two first positioning surfaces 12.

[0069] Reference Figure 6-Figure 8The first and second positioning members 23 are connected to each other on at least one side of the first and second positioning members 23 along the third direction, and the first central axis a extends along the third direction. The mounting block 23 is accommodated in the positioning cavity 13, and the positioning cavity 13 is open on one side along the third direction to form a disassembly opening 131 for disassembling and assembling the second positioning member 2. A through hole 11 is provided on the wall of the positioning seat opposite to the disassembly opening 131, and two limiting grooves 231 are arranged at intervals along the circumference of the mounting block 23 on the outer peripheral wall. The bottom wall of the limiting groove 231 constitutes the second positioning surface 22, and two limiting ribs 14 are arranged at intervals along the circumference of the positioning cavity 13 on the inner peripheral wall. The limiting ribs 14 facing the mounting block 23 constitute the first positioning surface 12.

[0070] The positioning cavity 13 facilitates the accommodation of the mounting block 23 therein and makes the overall structure of the mounting block 23 and the positioning seat compact. The disassembly opening 131 facilitates the installation of the mounting block 23 into the positioning cavity 13. A through hole 11 is provided on the wall of the positioning seat opposite the disassembly opening 131. Since the positioning post 21 is located on at least one side of the mounting block 23 along the third direction, the positioning post 21 can be easily inserted through the hole 11 into the positioning mounting hole 200 when the mounting block 23 is installed in the accommodation cavity.

[0071] Two limiting grooves 231 are provided on the outer peripheral wall of the mounting block 23 and are arranged at intervals along the circumference of the mounting block 23. Two limiting ribs 14 are provided on the inner peripheral wall of the positioning cavity 13 and are arranged at intervals along the circumference of the positioning cavity 13. The bottom wall of the limiting groove 231 constitutes the second positioning surface 22, and the surface of the limiting rib 14 facing the mounting block 23 constitutes the first positioning surface 12. The limiting groove 231 can facilitate the insertion of the limiting rib 14 therein, and can make the overall structure of the mounting block 23 and the positioning seat compact. Through the cooperation between the limiting groove 231 and the limiting rib 14, the mounting block 23 can be limited, and the stability of the mounting block 23 after assembly in the positioning seat can be improved.

[0072] Reference Figure 2 、 Figure 13 and Figure 14 According to some embodiments of the present invention, the groove depths of the two limiting grooves 231 are different, so that the distances between the two second positioning surfaces 22 and the central axis of the second positioning member 2 are different. For example, by adjusting the matching positions of the two limiting grooves 231 and the two limiting ribs 14, the position of the second positioning member 2 relative to the first positioning member 1 along the second direction can be adjusted.

[0073] For example, the distances between the bottom walls of the two limiting grooves 231 and the first center axis are L1 and L2 respectively, and the difference between L1 and L2 is N1, so that the mounting block 23 can be flipped 180° along the second direction. In this way, the positional relationship of the two limiting grooves 231 can be adjusted, so that the second positioning member 2 can be offset by N2 relative to the first positioning member 1 along the second direction, and through the cooperation of the two limiting grooves 231 and the limiting rib 14, the position adjustment distance of the second positioning member 2 relative to the first positioning member 1 along the second direction can be more accurately controlled.

[0074] Reference Figure 2 、 Figure 4 and Figure 8 According to some embodiments of the present invention, two limiting ribs 14 are located at opposite ends of the first positioning member 1 along the second direction. The inner circumferential wall of the positioning cavity 13 is further provided with two limiting grooves 15. The two limiting grooves 15 are located at opposite ends of the first positioning member 1 along the first direction. The mounting block 23 is provided with limiting protrusions 232 on opposite sides of the limiting grooves 15, respectively. The two limiting ribs 14 are located at opposite ends of the first positioning member 1 along the second direction. The limiting ribs 14 on opposite ends of the first positioning member 1 along the second direction cooperate with the limiting grooves 231 of the mounting block 23 to limit the mounting block 23 in the second direction. The two limiting grooves 15 on opposite ends of the first positioning member 1 along the first direction cooperate with the limiting protrusions 232 on opposite sides of the mounting member to limit the mounting block 23 in the first direction. This further enhances the stability of the mounting block 23 after assembly on the mounting seat and reduces or prevents movement of the mounting block 23 in the first direction on the mounting seat due to external impact or vibration.

[0075] Reference Figure 1 、 Figure 15 and Figure 16 According to some embodiments of the present invention, the multiple different assembly states also include a fourth assembly state. In the fourth assembly state, the first center axis a is offset relative to the second center axis b in both the first direction and the second direction. When the second positioning member 2 is in the first assembly state, one of the positioning posts 21 of the second positioning member 2 passes through the hole 11 and is provided in the first positioning member 1, and the positioning post 21 is installed in the positioning installation hole 200 so that the second positioning member 2 is installed on the second component. At this time, the first center axis a and the second center axis b are collinear. When the second positioning member 2 is in the fourth assembly state, the first center axis a is offset relative to the second center axis b in both the first direction and the second direction. In this way, the first component can be offset relative to the second component in both the first direction and the second direction.

[0076] For example, the process of adjusting the second positioning member 2 from the first assembly state to the fourth assembly state can be: rotating the second positioning member 2 180° along the first direction, and making one of the positioning columns 21 disengage from the through hole 11 and the positioning mounting hole 200, and flipping the second positioning member 2 180° along the third direction, and then inserting the other positioning column 21 into the through hole 11 and cooperating with the mounting positioning hole, so that the first center axis a can be offset relative to the second center axis b in both the first direction and the second direction, thereby achieving the first component offset relative to the second component in both the first direction and the second direction.

[0077] Reference Figure 4 、 Figure 5 and Figure 9 According to some embodiments of the present invention, the first positioning member 1 is formed as a positioning seat, a positioning cavity 13 is provided in the first positioning member 1, and the second positioning member 2 includes a mounting block 23 and a positioning column 21. The positioning column 21 is connected to at least one side of the mounting block 23 along the third direction, and the first center axis a extends along the third direction. The mounting block 23 is accommodated in the positioning cavity 13, and the positioning cavity 13 is open on one side along the third direction to form a disassembly opening 131 for disassembling and assembling the second positioning member 2. A through hole 11 is provided on the wall of the positioning seat opposite to the disassembly opening 131. The positioning seat can fix and support the mounting block 23. By accommodating the mounting block 23 in the accommodating cavity and the positioning column 21 through the hole 11 and cooperating with the positioning mounting hole 200, the positioning of the second component on the first component can be assisted. By adjusting the position of the first center axis relative to the second center axis, the position of the second positioning member 2 relative to the first positioning member 1 can be adjusted to adjust the position of the second component relative to the first component.

[0078] Reference Figure 2 、 Figure 3 and Figure 9 According to some embodiments of the present invention, a limiting spring buckle 16 is provided on the positioning seat, and the end face of the mounting block 23 close to the disassembly and assembly port 131 in the third direction is the mounting end face 233. The limiting spring buckle 16 abuts against the mounting end face 233 in the third direction. The limiting spring buckle 16 abuts against the mounting end face 233 of the mounting block 23 in the third direction, so that the connection between the positioning seat and the mounting block 23 can be simple and have strong stability.

[0079] For example, the limiting spring buckle 16 can be an elastic member. When the mounting protrusion is removed from the positioning seat, the free end of the limiting spring buckle 16 is elastically deformed along the first direction toward the direction away from the positioning seat to release the connection between the limiting spring buckle 16 and the mounting end face 233 to facilitate the removal of the second positioning member 2 from the first positioning member 1. After the mounting protrusion is accommodated in the positioning cavity 13, the limiting spring buckle 16 is restored to the position abutting the mounting end face 233 in the third direction due to its own elastic restoring force.

[0080] In this embodiment, the mounting end surface 233 of the second positioning member 2 is in a cross shape. Optionally, the mounting end surface 233 of the second positioning member 2 may also be in various forms such as a straight line shape or a triangle shape.

[0081] Optionally, the assembly force range of the second positioning member 2 on the first positioning member 1 is 40N to 120N, and the disassembly force range is 70N to 120N. This can better balance the difficulty of assembling or disassembling the second positioning member 2 on the first positioning member 1 and the connection strength. The operator can use moderate force to complete the assembly or disassembly between the second positioning member 2 and the first positioning member 1, without damaging the second positioning member 2 or the first positioning member 1 due to excessive force, nor will the connection strength be too low due to too little force. This ensures a strong connection strength between the second positioning member 2 and the first positioning member 1, and also avoids difficulty in assembly and disassembly due to excessive connection strength between the second connector and the first connector.

[0082] Among them, the magnitude of the assembly force and the disassembly force is related to the material type of the first positioning member 1, the height of the limiting spring buckle 16, and the effective clamping length of the limiting spring buckle 16. The higher the bending modulus of the material used for the limiting spring buckle 16, the greater the assembly force and the disassembly force. The height of the limiting spring buckle 16 is inversely proportional to the assembly force and the disassembly force. The higher the height of the limiting spring buckle 16, the smaller the assembly force and the disassembly force. The effective clamping length of the limiting spring buckle 16 is the length of the overlapping area between the limiting spring buckle 16 and the mounting end face 233. The number of limiting spring buckles 16 can be one or more, and the assembly force and the disassembly force increase exponentially with the number of limiting spring buckles 16.

[0083] Reference Figure 1 、 Figure 3 and Figure 5 According to some embodiments of the present invention, the first positioning member 1 and the second positioning member 2 are connected by a snap-fit ​​structure, which can make the connection between the first positioning member 1 and the second positioning member 2 simple and have strong stability, and make the installation or disassembly between the first positioning member 1 and the second positioning member 2 more convenient.

[0084] Alternatively, the first positioning member 1 and the second positioning member 2 are connected by fasteners, which can make the connection between the first positioning member 1 and the second positioning member 2 simple and have strong stability, and make the installation or disassembly between the first positioning member 1 and the second positioning member 2 more convenient.

[0085] Reference Figure 3 and Figure 4 The vehicle according to the second embodiment of the present invention includes the positioning structure 100 according to the first embodiment of the present invention.

[0086] According to the vehicle of the embodiment of the present invention, the above-mentioned positioning structure 100 is provided, and the first positioning member 1 is detachably connected to the second positioning member 2, and the second positioning member 2 is detachably connected to the second component. After the second component is assembled with the first component, if the error between the second component and the first component exceeds the requirement, the second positioning member 2 can be removed from the second component, and the position of the second positioning member 2 relative to the first positioning member 1 can be adjusted to change the assembly state of the second positioning member 2, and then the second positioning member 2 can be installed to the second component. In this way, the position of the second component relative to the first component can be adjusted so that the error between the second component and the first component meets the requirement. There is no need to modify the production mold to change the structure. It is only necessary to remove the second positioning member 2 from the second component and adjust the position of the second positioning member 2 relative to the first positioning member 1. This makes the operation of adjusting the position of the second component relative to the first component simpler, shortens the time required for position adjustment, and reduces costs.

[0087] Reference Figure 3 and Figure 4 According to some embodiments of the present invention, the first component is an interior trim panel of a vehicle body, and the second component is a sheet metal part of the vehicle body. A first positioning member 1 is connected to the interior trim panel of the vehicle body, and a second positioning member 2 is detachably connected to the sheet metal part of the vehicle body. The second positioning member 2 has multiple different assembly states relative to the first positioning member 1. The position of the interior trim panel relative to the sheet metal part can be adjusted by adjusting the position of the second positioning member 2 relative to the first positioning member 1. Thus, even if there is an assembly error between the interior trim panel and the sheet metal part, the relative position between the interior trim panel and the sheet metal part can be adjusted by adjusting the assembly state of the second positioning member 2. This shortens the time required for relative position adjustment between the interior trim panel and the sheet metal part, and reduces costs.

[0088] The positioning structure 100 meets the requirements for abusive force. For example, when the interior trim panel is mounted to the sheet metal, if the positioning post 21 is not aligned with the mounting hole, the positioning post 21 is unlikely to dislodge from the first component within an installation force range of 90N to 190N, ensuring the overall reliability of the positioning structure 100. For another example, after the interior trim panel is mounted to the sheet metal, the positioning structure 100 is unlikely to suffer permanent damage under a force of no more than 600N. Even under varying environmental conditions, such as low temperatures of -40°C, ambient temperatures of 23°C, and high temperatures of 95°C, the requirements for no dislodgment and no damage under stress are met.

[0089] Optionally, the height of the positioning column 21 needs to be determined based on the deformation of the positioning column 21 under the rated torque condition. By measuring the overall weight of the interior trim panel, the rated force value of the positioning column 21 is calculated, and then the deformation of the positioning column 21 under the rated torque condition is calculated. Under the rated force value F (F = weight of the interior trim panel), the length of the arm of the positioning column 21 is W, and the rated torque generated is F*W. Through simulation, it is calculated that the deformation of the positioning column 21 under the torque of F*W is ΔT, and ΔT must meet the following requirements: ΔT≤0.2mm. This ensures that under the rated torque condition, the deformation of the positioning column 21 is within an acceptable range, thereby ensuring the accuracy and reliability of the positioning structure 100.
