[0002] In the assembly of automobile parts, some interior decoration parts need to be fixed on the body sheet metal, and bolts and other fasteners are mainly used for fixing and installation. However, due to the thin thickness of some body sheet metals, it is not suitable for drilling threaded holes. It is necessary to use the body sheet metal to install the nut seat, and fix the interior decoration parts to be fixed on the nut seat with screws to achieve the fixation of the interior decoration parts and the body sheet metal.

[0003] Existing nut seats are generally made of metal or plastic. Although metal nut seats are durable, they are heavy and expensive to make. Plastic nut seats are light, cheap, and do not need to be welded to the body sheet metal. However, the plastic nut seat is connected to the screw thread. During the tightening process, the internal thread hole of the plastic is easily damaged, causing the screw to slip. Or after the screw is tightened, as the vehicle is used for a longer time, the internal thread hole that matches the screw is easily damaged, causing the screw to loosen, which in turn causes the interior panel to not be tightened in place, which is very likely to cause abnormal noise during driving and cause complaints from passengers.

[0042] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] Please also read Figures 1 to 4 Now, the nut seat provided by the utility model is described. The nut seat comprises a plastic seat body 1 and a metal inner sleeve 2. The plastic seat body 1 is used to be fixed on the body sheet metal 4; the plastic seat body 1 is provided with a through hole 11; the metal inner sleeve 2 is fixed in the through hole 11; the metal inner sleeve 2 has an internal threaded hole, and the internal threaded hole is used for threaded connection with a screw 3. Among them, the plastic seat body 1 is used to abut against the interior decoration 5, and the interior decoration 5 is fastened to the metal inner sleeve 2 by the screw 3.

[0044] The plastic seat 1 is fixed on the body sheet metal 4, and the plastic seat 1 is in contact with the interior decoration 5 to reduce the distance between the interior decoration 5 and the body sheet metal 4. The plastic seat 1 can be embedded in the body sheet metal 4, or can be screwed on the body sheet metal 4. Since the overall structure of the plastic seat 1 is relatively small, even if the part where the body sheet metal 4 and the plastic seat 1 are connected is relatively thin, the plastic seat 1 can be fixed on the body sheet metal 4 by using screws and nuts.

[0045] The plastic base body 1 is provided with a through hole 11. Preferably, the through hole 11 penetrates along the thickness direction of the plastic base body 1, and the center line of the through hole 11 coincides with the center line of the thickness direction of the plastic base body 1, so that the plastic base body 1 is subjected to balanced force.

[0046] The metal inner sleeve 2 is fixed in the through hole 11. Preferably, the through hole 11 is a light hole, and the metal inner sleeve 2 and the through hole 11 are interference fit. During assembly, the metal inner sleeve 2 is directly embedded in the through hole 11, and the metal inner sleeve 2 cannot be removed. Since the metal inner sleeve 2 is located in the through hole 11, it is small in size, does not occupy additional space, and has little effect on the weight of the entire nut seat.

[0047] When the nut seat provided by the utility model is used in a specific application, the plastic seat body 1 is first fixed on the body sheet metal 4, and then the interior decoration part 5 is abutted against the plastic seat body 1. Finally, a screw 3 is used to pass through the interior decoration part 5 into the internal threaded hole, and the screw 3 is tightened to fix the interior decoration part 5 on the body sheet metal 4.

[0048] The metal inner sleeve 2 is preferably a steel inner sleeve, which is made of the same material as the screw 3. The inner wall of the metal inner sleeve 2 forms an internal thread. The metal inner sleeve 2 and the screw 3 are threaded together, and the connection strength is high, which avoids the internal thread from slipping. Moreover, the metal inner sleeve 2 has high strength and will not be damaged. It will not loosen after being in cooperation with the screw 3 for a long time, which ensures the fastening effect of the interior decoration 5.

[0049] Compared with the prior art, the nut seat provided by the utility model is provided with a through hole 11 on the plastic seat body 1, and a metal inner sleeve 2 is fixed in the through hole 11, so that the metal inner sleeve 2 is threadedly connected with the screw 3, thereby preventing the screw 3 from slipping during the tightening process and preventing the screw 3 from loosening after long-term use and generating abnormal noise; moreover, the metal inner sleeve 2 only needs to have an internal thread, and its structure is simple, the volume is small, and no additional space is occupied, so that the overall weight of the nut seat is light and the production cost is low, which meets the development demand of lightweight whole vehicles.

[0050] In some embodiments, the plastic base 1 and the metal inner sleeve 2 may be connected by Figure 3 and Figure 4 The structure shown, see Figure 3 and Figure 4 The through hole 11 includes a through hole 111 and a limiting hole 112 connected in sequence. The aperture of the limiting hole 112 is larger than the aperture of the through hole 111, and a step surface 113 is formed at the junction of the limiting hole 112 and the through hole 111; the metal inner sleeve 2 is fixed in the limiting hole 112, and one end of the metal inner sleeve 2 is in contact with the step surface 113.

[0051] The step surface 113 is used to limit the axial position of the metal inner sleeve 2. When the metal inner sleeve 2 is inserted into the through hole 11, when the end surface of the metal inner sleeve 2 abuts against the step surface 113, it means that the metal inner sleeve 2 is assembled in place. In addition, the step surface 113 can also limit the axial movement of the metal inner sleeve 2 toward the interior decoration 5, avoiding the movement of the screw 3, thereby ensuring that the screw 3 presses and fixes the interior decoration 5 and the body sheet metal 4.

[0052] Preferably, the length of the metal inner sleeve 2 is equal to the length of the limiting hole 112 , that is, one end of the metal inner sleeve 2 abuts against the step surface 113 , and the other end is flush with the end surface of the plastic base body 1 .

[0053] In some embodiments, the body sheet metal 4 and the plastic base 1 may be connected by Figure 2 and Figure 3 The structure shown, see Figure 2 and Figure 3 A mounting hole 41 is provided on the body sheet metal 4, and the plastic seat body 1 is embedded in the mounting hole 41.

[0054] The plastic base 1 is connected to the body sheet metal 4 by embedding, that is, the plastic base 1 is directly fixed to the body sheet metal 4. On the one hand, the intermediate connecting parts connecting the body sheet metal 4 and the plastic base 1 can be saved, and there is no need to make too many changes to the body sheet metal 4. It is only necessary to open the mounting hole 41. On the other hand, it is only necessary to embed the plastic base 1 in the mounting hole 41, which simplifies the assembly operation of the nut seat.

[0055] In some embodiments, the plastic base 1 may be made of Figure 1 , Figure 2 and Figure 3 The structure shown, see Figure 1 , Figure 2 and Figure 3 The plastic seat body 1 includes a limit plate 13, an embedding seat 14 and a clamping structure 12. The limit plate 13 is located on one side of the body sheet metal 4; one end of the embedding seat 14 is connected to the limit plate 13, and the other end passes through the mounting hole 41; the clamping structure 12 is connected to the limit plate 13 or the embedding seat 14, and the clamping structure 12 also passes through the mounting hole 41. The limit plate 13 abuts against one side of the body sheet metal 4, and the clamping structure 12 abuts against the other side of the body sheet metal 4.

[0056] Preferably, one surface of the limiting plate 13 abuts against the side surface of the body sheet metal 4, and the other surface abuts against the interior trim 5. One end of the mounting seat 14 is connected to the surface of the limiting plate 13. The diameter of the limiting plate 13 is larger than the inner diameter of the mounting hole 41 and also larger than the diameter of the mounting seat 14.

[0057] The through hole 11 is formed on the limiting plate 13 and the embedding seat 14. The thickness of the embedding seat 14 is much greater than that of the limiting plate 13. The limiting hole 112 is provided on the embedding seat 14. Preferably, the outer peripheral surface of the embedding seat 14 abuts against the hole wall of the mounting hole 41, so that the nut seat forms a limit in the radial direction of the mounting hole 41.

[0058] The clamping structure 12 can be connected to the limiting plate 13 or to the embedding seat 14. This embodiment does not limit the specific connection relationship of the clamping structure 12. The clamping structure 12 has the freedom to move along the radial direction of the embedding seat 14, so that the clamping structure 12 can pass through the mounting hole 41 and abut against the other side of the body sheet metal 4.

[0059] The limiting plate 13 and the clamping structure 12 are respectively in contact with the two side surfaces of the body sheet metal 4, that is, the limiting plate 13 and the clamping structure 12 can clamp the body sheet metal 4 so that the nut seat is limited in the axial direction of the mounting hole 41 to prevent the nut seat and the screw 3 from moving, thereby ensuring that the interior decoration part 5 is fastened to the body sheet metal 4 to prevent the interior decoration part 5 from shaking and producing abnormal noise.

[0060] See also Figure 1 , Figure 2 and Figure 3 On the basis of the above embodiment, the clamping structure 12 is a clamping block having an abutting inclined surface; one end of the clamping block is connected to the limiting plate 13, and the other end passes through the mounting hole 41, and the abutting inclined surface abuts against the body sheet metal 4.

[0061] One end of the card block is connected to the limit plate 13, so that there is a distance between the card block and the embedding seat 14. When passing through the mounting hole 41, the other end of the card block can be offset toward the embedding seat 14, thereby reducing the friction force of the card block passing through the mounting hole 41, making it easier to assemble the plastic seat body 1 with the body sheet metal 4.

[0062] In addition, the clamping block has an abutment slope, which is used to abut against the vehicle body sheet metal 4 on the one hand, and on the other hand, when passing through the mounting hole 41, the abutment slope first contacts the hole wall of the mounting hole 41. Since the abutment slope is inclined, it can be pushed by the hole wall of the mounting hole 41 to move toward the embedding seat 14, thereby further reducing the friction force when the clamping block passes through the mounting hole 41 and optimizing the assembly operation.

[0063] In some embodiments, the above-mentioned embedded seat 14 can be used as follows Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 The mounting seat 14 includes a column 141 and a plurality of limiting ribs 142. The column 141 is provided with the through hole 11; the plurality of limiting ribs 142 are evenly spaced and distributed on the outer peripheral surface of the column 141 along the circumference of the column 141, and each limiting rib 142 abuts against the hole wall of the mounting hole 41.

[0064] The limiting ribs 142 are located on the outer circumference of the column 141, so that there is a distance between the column 141 and the hole wall of the mounting hole 41. A plurality of limiting ribs 142 are evenly spaced on the column 141, and a weight-reducing groove is formed between each two adjacent limiting ribs 142. By using a plurality of limiting ribs 142 to abut against the hole wall of the mounting hole 41, on the first hand, the weight of the plastic seat body 1 can be reduced, and the plastic seat body 1 can be easily injection molded; on the second hand, the weight-reducing groove provides a space for slight deformation when the limiting ribs 142 pass through the mounting hole 41, so that the embedded seat 14 can quickly pass through the mounting hole 41 and form a radial limit with the mounting hole 41; on the third hand, the weight-reducing groove also provides space for installing the clamping structure 12, that is, the clamping structure 12 can be set between the two limiting ribs 142.

[0065] See also Figure 1 and Figure 2 On the basis of the above embodiment, the mounting hole 41 is a regular polygonal hole; a plurality of limiting ribs 142 correspond one-to-one to a plurality of corner points of the regular polygonal hole, and the outer peripheral surface of the limiting rib 142 abuts against the inner wall of the corresponding corner point.

[0066] The number of the limiting ribs 142 is the same as the number of sides of the regular polygonal hole. Each limiting rib 142 has two outer wall surfaces set at an angle. The angle between the two outer wall surfaces is equal to the angle at the corner point of the regular polygon. Each limiting rib 142 can be limited by the regular polygonal hole in two directions respectively. After multiple limiting ribs 142 are combined, they can be completely limited by the regular polygonal hole on the radial plane of the regular polygonal hole.

[0067] In this embodiment, the mounting hole 41 is a regular polygonal hole. Compared with a circular hole structure, the contact area between the outer wall surface of the limiting rib 142 and the hole wall of the mounting hole 41 can be increased, thereby optimizing the fixing stability performance of the plastic seat body 1 and the vehicle body sheet metal 4. The structure of the limiting rib 142 can also be simplified, making the plastic seat body 1 easy to injection mold.

[0068] by Figure 2 For example, the mounting hole 41 in this embodiment is a square hole, and four groups of limiting ribs 142 are provided. The four groups of limiting ribs 142 are respectively arranged at the four corner points of the square hole.

[0069] In some embodiments, the plastic base 1 may also be made of Figure 1 and Figure 2 The structure shown, see Figure 1 and Figure 2 A reinforcing plate 143 is provided between two adjacent limiting ribs 142 , an avoidance hole is provided on the reinforcing plate 143 , and the clamping structure 12 is located at the avoidance hole.

[0070] There is a gap between the plate surface of the reinforcing plate 143 and the outer peripheral surface of the column 141 . When the plastic seat body 1 passes through the mounting hole 41 , the reinforcing plate 143 can be slightly offset toward the column 141 to ensure that the limiting rib 142 passes through the mounting hole 41 smoothly.

[0071] The reinforcing plate 143 is connected between two limiting ribs 142 to increase the strength of the plastic seat 1. It should be noted that the reinforcing plate 143 can be connected between every two adjacent limiting ribs 142, that is, the number of the reinforcing plates 143 is the same as the number of the limiting ribs 142, or the reinforcing plates 143 can be connected only between several groups of two adjacent limiting ribs 142.

[0072] In addition, the number of the snap-in structures 12 is also determined according to the shape of the mounting hole 41 . An avoidance hole can be set on each reinforcing plate 143 , and a snap-in structure 12 can be placed at each avoidance hole. Alternatively, a snap-in structure 12 can be placed at the avoidance holes of several or one reinforcing plate 143 .

[0073] by Figure 2 For example, the mounting hole 41 is a square hole, four groups of limiting ribs 142 are provided, two groups of reinforcing plates 143 are provided, and the two groups of reinforcing plates 143 are symmetrically distributed, and each group of reinforcing plates 143 has a clamping structure 12 at the avoidance hole.

[0074] In some embodiments, the plastic base 1 and the body sheet metal 4 may be connected by Figure 1 and Figure 3 The structure shown, see Figure 1 and Figure 3 A shock-absorbing gasket 15 is also provided between the limiting plate 13 and the body sheet metal 4.

[0075] The shape of the shock-absorbing gasket 15 matches the shape of the limiting plate 13. The shock-absorbing gasket 15 is arranged between the limiting plate 13 and the body sheet metal 4 to prevent the limiting plate 13 from hard contact with the body sheet metal 4 and to alleviate the vibration of the body sheet metal 4 to the nut seat. In addition, the shock-absorbing gasket 15 also has a waterproof effect.

[0076] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, including a body sheet metal 4, the above-mentioned nut seat, an interior decoration 5 and a screw; the interior decoration 5 abuts against the nut seat; the screw 3 passes through the interior decoration 5 and is fastened in the internal threaded hole.

[0077] The nut seat is fixed on the body sheet metal 4, and the nut seat abuts against the interior decoration 5 to reduce the distance between the interior decoration 5 and the body sheet metal 4. The nut seat can be embedded in the body sheet metal 4, or can be screwed on the body sheet metal 4. Since the overall structure of the nut seat is small, even if the part where the body sheet metal 4 and the nut seat are connected is thin, the nut seat can be fixed on the body sheet metal 4 by using screws and nuts.

[0078] When the nut seat provided by the utility model is used in a specific application, the nut seat is first fixed on the body sheet metal 4, and then the interior decoration part 5 is abutted against the nut seat, and finally a screw 3 is used to pass through the interior decoration part 5 into the internal threaded hole of the metal inner sleeve 2, and the screw 3 is tightened to fix the interior decoration part 5 on the body sheet metal 4.

[0079] The vehicle provided by the utility model adopts the above-mentioned nut seat, so that the interior decoration part 5 can be fastened to the metal inner sleeve 2 of the nut seat by means of the screw 3. The metal inner sleeve 2 is threadedly connected with the screw 3, and the connection strength is high, thereby preventing the screw 3 from slipping during the tightening process and preventing the screw 3 from loosening after long-term use, thereby improving the fixing stability of the interior decoration part 5, avoiding abnormal noise during driving, and improving riding comfort.

[0080] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
